Different Types of Health Insurance in California
Posted on November 05, 2008 in Generic prescription drug list
Different Types of Health Insurance in California By: WittyArticles Different Types of Health Insurance in California Whether you buy group or individual health in California, the options you have regarding the different types of health insurance are generally the same. In some groups you can even choose from available plans. These different types are traditional health insurance, health maintenance organizations (HMOs), and preferred provider organizations (PPOs). California goes beyond the Federal requirements for offering health insurance to its residents. Examples of this include Industry Advantage plans (IAHP), short-term health policies, Insurance for high risk Individuals and special plans for children and teens. Additional Health Insurance in California The traditional health care delivery system is based on a fee-for-service type of arrangement. In a fee-for-service system, you pay or each itemized medical service you receive. In the days of the frontier, "Doc" often received a chicken as payment. Today, physicians are paid with money, lots and lots of it. Fee-for-service health insurance recognizes this practice and is designed to reduce or even eliminate your duty to pay directly for your medical care. Traditional health insurance comes in three parts: California has four basic options for choosing a health care plan: 1. Health through an employer or association 2. Health Insurance through Income eligibility such as Medicaid 3. Health care for high risk individuals such as those that have had cancer or a heart attack 4. Private Insurance Hospitalization Hospitalization covers defined expenses incurred while in the hospital. Generally, the insurance will pay for all of the covered services rendered by the hospital staff. However, if the insurance benefit is an indemnity payment, the payment will be for a fixed sum regardless of the actual expenses incurred. This fixed sum will usually be far below the daily charge actually made by the hospital. Medical/surgical This part of a traditional health plan covers the expensive costs of medical care other than the bill from the hospital. Services such as doctor visits, treatment charges, etc., are covered here. Medical/surgical usually has a deductible and requires co-payments by the insured (payments you make for charges not covered by the insurance), typically 20 percent of the doctor's fee. Catastrophic or major medical There are usually lifetime maximum payments that hospitalization and medical/surgical plans will pay, after which the well runs dry. Unfortunately, these maximums may not be sufficient to pay for all of the care required if a major illness or injury should strike, since such afflictions can eat up hundreds of thousands or even millions of dollars worth of health services. Thus, catastrophic coverage adds to your umbrella of protection in an amount sufficient to protect you from the horrendous expenses of such serious and prolonged illnesses. These policies also fill in some of the gaps not covered by hospitalization or medical/surgical. Health Maintenance Organizations or Private Insurance in California The health maintenance organization (HMO) is a relatively new player in the health insurance game, although it has been around in a limited fashion since the 1930s. The idea behind an HMO is to pay one premium and receive all of your health care at no or a nominal additional cost. The point is to save money compared to traditional health plans that cost more to purchase and require more out-of-pocket payments from the insured. What you, the insured, give in exchange for reduced cost is a substantial loss of your freedom to choose who will take care of your health needs. Preferred Provider Organizations Preferred provider organizations (PPOs) seek to give both the benefits of traditional health plans and the money savings of HMOs. They do this by paying higher benefits as a reward for your using the doctors or hospitals they preselect for that purpose. Disability Insurance Disability insurance does not pay for health care; rather it pays for lost wages caused by a disabling injury or illness. How Health Insurance Is Priced Ask anyone how health insurance is priced and you will get a simple answer: expensively! Beyond that, there are underwriting criteria used by health insurance providers, whether they are for-profit or, like Blue Shield/Blue Cross, nonprofit. Underwriting Criteria Age. The older you are, the more likely you are to get sick; therefore, the higher your health insurance premiums will be. Number of people covered. Many people buy family coverage rather than individual policies. This means that there will be adults as well as minor children protected by the same plan. Some companies will charge based on the size of the family. Others charge a basic family rate without regard to the number of members. Gender. Unlike life insurance, where women get the better end of the bargain than men, in health insurance women often pay higher premiums. This is based on health insurance industry statistics which indicate that the female of the species tends to need medical care more often than the male. Health history. Insurance operates on statistical probabilities. If you have had a poor health history, statistically you are more likely to have a more expensive health care future. This, in turn, means that you will pay higher premiums-if you can get health insurance at all. Occupation. The more likely you are to suffer injury or illness because of the work you do, the more likely the health insurance industry will be to charge excessively for benefits. This may be well and good for professional deep-sea divers. But the industry has begun to stretch the concept into areas that have nothing to do with the inherent danger of the work. Lifestyle. In your application for health insurance you will be asked questions about your personal habits. Your answers will have a lot to do with the cost of your premiums. If you smoke, you will probably pay more for health insurance. If you drink to excess, you will probably pay more for health insurance. If you are known to be under a great deal of stress, you may pay more for health insurance. California does reward the health care Insurance consumer with lower premiums if they have practiced good health policies. One of the most important things you can do as a health care consumer is to engage in preventive care. Not only will you be able to spot serious diseases at an early stage, thereby increasing your chances of effective treatment and cure, but you should be able to save money as well, since it is usually far less expensive to treat a disease when it's a molehill rather than a mountain.

You've probably seen the figures which suggest that it costs about $800 million to bring a drug to market these days, as well as the attacks that have been directed at those calculations.

Type 2 Diabetic
Posted on October 06, 2008 in Diabetes erectile dysfunction
Author: koolspaces.com Now, I am not a doctor and I don't play one on T.V. but after living with diabetes for seven years I've learned some things that I haven't seen while researching diabetes. Most of the things you learn are the basics, e.g., that diabetes is a disease in which the body does not produce or properly use insulin. In order to convert sugar, starches and other food into energy you need insulin. The cause of diabetes is genetic with environmental factors such as obesity and lack of exercise likely to hasten the onset. My hope is if you are having difficulty with some aspect of diabetes this article may provide some insight to you. As always, check with your doctor prior to incorporating any changes to your daily regimen as each person is unique and may or may not have success with my experiences. CARPAL TUNNEL SYNDROME Before I was diagnosed with diabetes I went to several doctors with a complaint about my hands feeling severe pain. I especially felt it during a swing of a golf club. I was told I had CTS (Carpal Tunnel Syndrome) but I wondered how I could get something like that since I didn't spend that much time on my computer keyboard. I was also skeptical of the diagnosis because the nurse practitioner treating me left the room before reaching a verdict then returns and tells me I have CTS. I guess she discussed my symptoms with the presiding doctor. Later that week, I read an article saying that if your doctor diagnoses you with CTS ask him to give you a simple blood test to rule out more serious diseases like cancer and diabetes. I showed the article to my doctor who agreed and lo and behold when the test came back it showed I had diabetes. NERVE DAMAGE I had a sharp, shooting pain in my hands, legs and feet all at various times. My doctor suggested exercise. I didn't like jogging because I seem to aggravate my right knee when I do run. I have easy access to a pool but don't really enjoy it enough but I liked the idea of riding a bicycle around my neighborhood. The fresh air, meeting neighbors and taking it light on my knee seemed appealing to me. The trick is to find some form of exercise you can tolerate and keep up with. If you don't like jogging chances are you won't maintain the exercise required. You need ninety minutes of exercise a week. I usually like to exercise during the late afternoon but because of a hot spell I decided to exercise during the morning to escape the hot weather. To my surprise my glucose readings were somewhat high before dinner. So I went back to exercising at 4 p.m. and my glucose reading fell back considerably. I reasoned that my biggest meal of the day was dinner and exercising a few hours before dinner helped regulate my glucose. Also, I noticed my readings weren't affected much when I exercised 15 minutes, or even twenty minutes. It seemed to me that I wasn't benefitting from that amount of time spent exercising. But when I extended it to 25 and especially 30 minutes, I noticed the difference. My appetite wasn't as ravenous and I felt better overall. But best of all, the nerve damage to my legs and hands were gone. No more numbness in those areas as well. The only complaint I had was the amount of time it took me to get there, 3 - 6 months. Aren't we all impatient? I was so encouraged by the results that exercising has become a way of life for me. Now I bicycle 3 to 4 miles per day, 5 days a week. In fact, on the days that I do miss my workout I feel guilty. INFECTIONS I recently had a continuous spell of high glucose readings of which I had no rational explanation as to why. My exercise regimen was usual and my eating habits and weight were the same. I began taking Glyburide once a day. Even that didn't work. Concerned, I made a doctor's appointment and thanks to my doctor asking questions (innocuous I thought at the time) it turned out that I had an infection on my arm. As soon as I took the antibiotics, my glucose levels returned to where they previously were. I cut the pills in half (from 5 milligrams to 2.5) because when I was first prescribed the Glyburide I was not told about the side effects of the medication. I remember walking in the park and feeling terrible. I thought I was going to die. I made it home and took a glucose reading and was alarmed that it was 35. (Normal is between 70 and 125.) I called my doctor and relayed what was going on and they advised me to get some sugar in my body. I did and felt better within minutes. Today, I keep tomato juice in my refrigerator in case I need it. Don't make the mistake I made and try to raise your blood sugar with food. Food will take 15 minutes to digest and may raise it over the level you want thereby negating your goal. After taking the Glyburide during my fight with that infection, I had an Hba1c test and I was surprised that my lipid profile improved considerably. Also, I am glaucoma-suspect and my eye pressure level was reduced 26%! Is there a correlation between Glyburide and my improvements in these areas -- I don't know but I anxiously await my next quarterly blood lipid test. There is a positive side to diabetes. Now I'm forced to exercise, watch what I eat and keep tabs on my weight. None of which I did before. The result from all this is a healthier lifestyle, less complications from diabetes and a longer lifespan. Diabetes can be manageable. Consider it a wakeup call to a healthier lifestyle. I can't stress enough that before you make any changes to your daily regimen to talk it over with your doctor. Write all of your questions down before you go in and if you're too shy to ask, hand him your piece of paper. koolspaces.com The Best myspaces on myspace.com The Best Funny Videos!

Narcotic 'lollipop' is big seller
Posted on September 05, 2008 in Prescriptions
By JOHN CARREYROU / The Wall Street Journal While pregnant with her second child three years ago, Tiare Frontera suffered from bad migraines. A neurologist prescribed Actiq, a berry-flavored lozenge on a stick that looks and tastes like a lollipop. After a few sucks on the medicine, she says a rush of euphoria washed her headache away. Soon, Mrs. Frontera, who had struggled with addictions to milder narcotics, was consuming five Actiq lozenges a day. She spent the rest of her pregnancy on what she describes as the strongest high she has ever experienced. When she gave birth, her baby son was cranky and wouldn’t sleep. Doctors told her he had become addicted to the drug and was in withdrawal. Mrs. Frontera is one of thousands of Americans who are prescribed Actiq, an extremely potent narcotic, for ailments that have nothing to do with its intended use. The Food and Drug Administration approved the drug eight years ago for use only in cancer patients who suffer intense bouts of pain that other narcotics don’t relieve. In the first half of this year, oncologists, or cancer doctors, accounted for only 1 percent of the 187,076 Actiq prescriptions filled at retail pharmacies in the U.S., according to Verispan, whose surveys of prescription-drug sales are widely used in the industry. Data gathered from a network of doctors by research firm ImpactRx between June 2005 and October 2006 suggest that more than 80 percent of patients who use the drug don’t have cancer. Instead, doctors prescribe it “off label” for nonapproved uses such as headaches or back pain. Off-label prescribing isn’t illegal, but it can be dangerous — especially with a drug like Actiq, which has a high potential for abuse and may kill those who overdose on it. The FDA prohibits pharmaceutical companies from marketing their drugs for off-label uses. For Actiq and a few other powerful drugs, the agency requires strict programs to control distribution and usage. Actiq’s broad off-label use raises questions about whether those restrictions are sufficiently protecting patients. “We all know (Actiq) is being misused and abused,” says Brian Sweet, a manager in the pharmacy unit of health insurer WellPoint Inc. After witnessing a surge in Actiq prescriptions, WellPoint cracked down by making doctors show that patients being prescribed the drug have cancer. Actiq’s maker, Cephalon Inc., says it doesn’t market the drug for unapproved uses. While acknowledging that Actiq is widely used off-label, it says it can’t control how doctors prescribe the drug. Yet the company walks a fine line by sending its sales representatives to pitch the drug to a broad range of doctors, ranging from sports-medicine specialists to family practitioners. It gives these doctors coupons for free samples. Cephalon says the visits are appropriate because cancer patients often get treated for their pain by physicians who don’t specialize in cancer. Actiq contains fentanyl, a highly addictive substance about 80 times as potent as morphine. Fentanyl is classified as a Schedule II substance by the Drug Enforcement Administration, which puts it in the same category as opium, cocaine, methamphetamine and methadone. Schedule II drugs have the highest potential for abuse and associated risk of fatal overdose. Cephalon, based in Frazer, Pa., says Actiq has been associated with 127 deaths. Two of them involved children who confused the drug for candy. Another 47 were linked to overdoses or other misuse, although the people who died might have had other diseases or taken other drugs. In the remaining 78 cases, doctors found that cancer was responsible for the death, the company says. Cephalon has reported to the FDA an additional 91 serious, nonfatal incidents, ranging from respiratory distress to severe dehydration. The U.S. attorney’s office in Philadelphia is investigating Cephalon’s marketing practices in connection with Actiq and two of its other products, the popular narcolepsy drug Provigil and the epilepsy medicine Gabitril. No charges have been filed. Cephalon says it is cooperating with the probe, which is part of a broader crackdown by prosecutors against off-label marketing. In August, the Justice Department fined Schering-Plough Corp. $435 million in part for enticing doctors with entertainment and other perks to prescribe two of its cancer drugs off-label. Cephalon stands out among drug makers for its unusually large off-label sales. Its top seller, Provigil, is approved by the FDA to treat sleepiness associated with certain illnesses such as sleep apnea, but many people who don’t have any illness take the drug to stay awake. Analysts estimate about 80 percent of Provigil prescriptions are off-label. Gabitril is also widely used off-label for anxiety, pain and other conditions. Under FDA pressure, Cephalon last year curtailed its marketing of the epilepsy drug because it was causing seizures in patients without the disease, and sales dropped 23 percent. Founded in 1987 by a former DuPont Co. scientist named Frank Baldino Jr., Cephalon expects revenue to exceed $1.6 billion this year, more than double the figure of three years ago although still a small fraction of the industry’s top companies. Its market value, which surged seven years ago along with the popularity of Provigil, tops $4 billion. Dr. Baldino earned $2.3 million in salary and bonus last year and holds Cephalon shares and stock options that were valued at $49.6 million as of the end of last year. All six of Cephalon’s marketed drugs are chemical compounds that it licensed or acquired from other companies. Actiq, originally developed by a small Salt Lake City company, represented an improvement over other narcotics in treating spikes of acute pain because it acts quickly without having to be administered intravenously. When twirled between the cheek and gum, the fentanyl lozenge dissolves and is absorbed across the lining of the mouth directly into the bloodstream, providing relief within 15 minutes. Actiq had sales of $15 million in 2000, when Cephalon acquired it. By last year, sales had grown to $412 million, making it Cephalon’s No. 2 drug. In the first nine months of this year, sales jumped to $471 million. Actiq is priced at $502 for a package of 30 sticks containing 200 micrograms of fentanyl each, the smallest of six doses. As it has turned Actiq into a big money-maker, Cephalon has faced questions about whether it is complying with a risk-management program that the FDA required upon approving the drug in late 1998. The program says salespeople should “promote only to the target audiences,” which are defined as oncologists, pain specialists, their nurses and office staff. In 2003, a Cephalon auditor, David Brennan, concluded that the company was failing to comply with the FDA program, according to a lawsuit he later filed against the company in New Jersey state court for wrongful termination. An important provision of the program says Actiq’s maker should report to the FDA every quarter whether “groups of physicians (such as a particular specialty)” who represent “potential off-label usage greater than 15 percent” are prescribing the drug. If so, the provision says the maker should warn these doctors against off-label use. Mr. Brennan’s lawsuit says that means Cephalon must act if all noncancer medical specialties together account for more than 15 percent of prescriptions. Cephalon interprets the provision differently. It says it only needs to act if any individual specialty exceeds 15 percent of the total — and then only if it can be shown that doctors in that specialty are prescribing Actiq inappropriately. Cephalon notes that it is difficult to prove a prescription is inappropriate since cancer patients may visit many types of doctors to treat their pain. It believes the 15 percent clause has yet to be triggered. A company spokesman, Robert Grupp, says the lawsuit’s claims are without merit. The FDA declined to comment. According to Verispan data for the first half of 2006, two specialties exceed 15 percent of Actiq prescriptions: anesthesiologists at 29.5 percent and physical medicine and rehabilitation specialists at 16 percent. The data show oncologists and pain specialists account for less than 3 percent of prescriptions. Cephalon doesn’t dispute the data. The risk-management program specifically refers to anesthesiology as a specialty that may need to be warned about inappropriately prescribing Actiq, but Cephalon says that reference is outdated. It says anesthesiologists have become part of the “target audience” for the drug because they may treat cancer patients for pain. Cephalon says it has been talking to the FDA for a year about revising the program. After Mr. Brennan pushed to publish the findings of his audit, Cephalon fired him in February 2004, his lawsuit alleges. Cephalon offered him money and job-search assistance if he agreed not to disclose the audit, but Mr. Brennan refused, the suit says. Mr. Grupp declined to discuss Mr. Brennan’s dismissal but noted that he is “a former disgruntled employee.” Mr. Brennan has been interviewed twice by investigators working for the U.S. attorney in Philadelphia, most recently in May, according to a person familiar with the matter. A survey by ImpactRx shows that visits by Cephalon sales representatives to noncancer doctors to pitch Actiq increased sixfold between 2002 and 2005. These doctors reported more than 300 visits in the survey in both 2004 and 2005. Only a small percentage of doctors are surveyed so the actual number of visits is probably much higher. Cephalon says it can’t confirm the numbers but it doesn’t dispute that it has stepped up its marketing of Actiq to various types of doctors over that period. Stephen Leighton, a general practitioner in Winston-Salem, N.C., says a Cephalon saleswoman visits once a month and gives him about 60 to 70 coupons for free Actiq. Patients can trade each coupon for six Actiq sticks. Dr. Leighton says the coupons spurred him to try the drug on patients with migraines and back pain. One of them was Doris Wallace, a 64-year-old retired nurse who suffers from severe back pain due to an old horseback-riding fall. Ms. Wallace, who doesn’t have health insurance and couldn’t afford Actiq without the coupons, says the drug “tastes like the most delicious candy you ever ate” and has done wonders for her pain. At the height of her use, she was consuming 24 Actiq sticks a month. The positive experience of patients like Ms. Wallace has led Dr. Leighton to prescribe Actiq more widely for different types of pain. Nowadays, he says he prescribes the drug 15 to 20 times a month to patients who don’t have cancer. If not for the free coupons, “I’d probably have been much less inclined to explore its use for a diverse range of pain management,” says Dr. Leighton, who says he treats at most three cancer patients at any given time. Dr. Leighton says he thinks the FDA-approved usage of Actiq is too narrow. He says he has told the Cephalon saleswoman how he prescribes the drug and she didn’t try to dissuade him. Mr. Grupp of Cephalon says Dr. Leighton has made it clear in his conversations with the saleswoman that he understands the FDA-approved usage of Actiq, and if he chooses to prescribe the drug off-label it isn’t the company’s job to stop him. Mr. Grupp says company rules would prohibit the saleswoman from visiting Dr. Leighton only if he never prescribed the drug for cancer pain. “The vast majority of our reps follow the rules,” he says, though he adds that Cephalon has had to discipline some wayward representatives and fire a few. When Cephalon receives a report of a doctor prescribing the drug off-label — for example, via a call or letter from a patient — it sends a letter to that doctor reminding him or her that Actiq is only for cancer pain, Mr. Grupp says. The company has sent more than 3,300 such letters, he says. Earlier this year, Dr. Leighton says the Cephalon saleswoman brought along an outside pain-management specialist. Over lunch, Dr. Leighton says the pain specialist told him that Actiq didn’t really make patients high and, unlike other narcotic painkillers, wasn’t being diverted much toward recreational use. Cephalon declined to comment on the conversation. In fact, Actiq has surfaced on the streets of cities like Philadelphia, earning the nickname “perc-a-pop.” Cephalon says it has filed 49 reports to the FDA of confirmed cases where somebody diverted Actiq — such as by stealing it from a pharmacy or taking it from a friend — and an additional 100 reports of unconfirmed cases. Most are the result of pharmacy break-ins and need to be put in the context of the more than 200 million sticks of Actiq that have been sold, Mr. Grupp says. Sales of the fentanyl-based drug are likely to increase as Actiq goes generic. In late September, Barr Pharmaceuticals Inc. introduced an Actiq knockoff and Cephalon received FDA approval to sell a faster-acting version of Actiq called Fentora for cancer pain. Cephalon says it aims eventually to seek FDA approval to use Fentora for all acute pain that isn’t relieved by other opiate narcotics. Mrs. Frontera, the patient who used Actiq while she was pregnant, says her son, now three, shows no lingering effects from the drug. Mrs. Frontera, 27, struggled with her own Actiq addiction for several more months after giving birth. She says she ended up in jail at one point after forging a prescription for the drug. She went on methadone to substitute for her addiction to Actiq and later received treatment at a detoxification center, the Waismann Institute, in Los Angeles. Now she lives in San Luis Obispo, Calif. “It makes me angry that it was prescribed to me,” she says of Actiq. “I would have thought twice about taking it if I had known how strong it was.” Philip Delio, the neurologist who prescribed Actiq to Mrs. Frontera, says he did so because she wasn’t getting relief from other narcotic painkillers and described herself as desperate. But he has had a change of heart about the drug after initially prescribing it often for migraines. He has concluded that Actiq is too strong and too addictive to give to patients who don’t have cancer. Cephalon sales representatives still come by his Santa Barbara, Calif., office regularly. But Dr. Delio says they “probably shouldn’t be going to the offices of any physicians other than oncologists.” Sphere: Related Content Cheap Generic Viagra

The Bird Flu Threat: Public Health Vs. Pharmaceutical Profits
Posted on August 23, 2008 in Generic medical release
FOR IMMEDIATE RELEASE NOVEMBER 2, 2005 8:00 AM CONTACT: Institute for Public Accuracy Sam Husseini, (202) 347-0020, (202) 421-6858; or David Zupan, (541) 484-9167 The Bird Flu Threat: Public Health Vs. Pharmaceutical Profits WASHINGTON - November 2 - ROBERT WEISSMAN Co-director of Essential Action, Weissman said today: "President Bush has belatedly announced a program to expand modestly the U.S. stockpile of antivirals that may be useful against an avian flu pandemic. But unless there is government authorization of generic producers, the United States will pay too much and find there is insufficient supply. Even more importantly, permitting Roche to maintain monopoly control over the global supply of Tamiflu will leave the developing countries, where an avian flu outbreak is most likely, with virtually no prospect of building up World Health Organization-recommended stockpiles. Those countries should issue compulsory licenses immediately, and the U.S. should give its blessing." Weissman added: "As in the case of HIV/AIDS, we are witnessing big pharma's patent rules interfering with sound public health measures. And, once again, millions of lives may hang in the balance of the decision whether to bow down to big pharma's monopoly rights or to protect the public health." More Information Dr. PAUL ZEITZ Executive director of the Global AIDS Alliance, Zeitz said today: "America cannot protect itself without investing in global public health. ... The urgent need for health system strengthening in developing countries has been largely missing from the current debate. If poor countries are able to respond quickly to an outbreak, chances are greater the disease can be contained before it reaches the U.S. ... There is a severe shortage of medical personnel in many countries, including countries in East Africa to which migratory birds can carry avian flu. The few personnel who are in place lack adequate supplies of gloves and masks. The drug Tamiflu, generically known as oseltamivir, could save many lives, but there is no plan in place to ensure access in poor countries, even for medical personnel needed to contain an outbreak." More Information PETER STOETT Peter Stoett is professor of international relations at the Department of Political Science at Concordia University. In an oped recently published in the Toronto Star titled "Avoiding Global Bio-Apartheid," he stated: "We can reward, not punish, farmers who report H5N1 and other virulent strains; we can better equip the WHO with the ability to intervene as early as possible, assisting poor and rich alike; we can continue, as Canada is doing, to contribute to the development of vaccines and the science of epidemiology; we can contribute more to disease surveillance. ... Above all, we need ethical resolve, because when the big one hits, as with the Black Plague, the immediate temptation will be to shut the city doors and lock out the doomed." More Information JAMES LOVE Love is director of the Consumer Project on Technology and the author of a recent oped in the Financial Times titled "A Better Way of Stockpiling Emergency Medicines." Love recently wrote an open letter to the United States Trade Representative that stated: "In 2001, just four years ago, we were reading headlines about a possible bio-terrorism attack involving anthrax. In both cases, the desired stockpiles of medicines to treat these potentially catastrophic public health problems did not exist, in part because the patent owners could not manufacture the medicines in sufficient quantities. "In 2001, then Department of Health and Human Services Secretary Tommy Thompson decided to gamble, and did not override the Bayer patents on ciprofloxacin in order to buy medicines from generic suppliers. As a consequence, the U.S. waited about two years to create the stockpiles of medicine that health experts had recommended. Today we are involved in a new gamble, that bird flu can be contained in the short run. Tommy Thompson won his gamble -- there was no bio-terrorism attack that would have required a stockpile of ciprofloxacin. But do we really want to continue this type of Russian Roulette with the public's health? ... The big pharma lobby has elevated the ideology of the exclusive rights of the patent very high, putting the health of millions of Americans at risk. This is a mistake, and should be corrected." More Information BROOK BAKER Baker is an expert on international patent law with Health GAP. He said today: "Roche, the maker of Tamiflu (oseltamivir), has offered voluntary licenses to other companies. ... [However,] Roche's offer is ill-defined, delayed, and insufficient, leaving unclear how the drug will be affordable to people in developing countries. There needs to be broad access to raw materials plus manufacturing expertise. In addition, the U.S. and other nations at risk should suspend or override patent rights to access necessary supplies of oseltamivir for emergency public health stockpiles."

Drugs from Canada
Posted on August 01, 2008 in Generic prescription drugs
In the Vice Presidential debate last night, John Edwards detailed the Kerry-Edwards health care plan, stressing, among other points, their intention to allow importation from Canada: They've blocked allowing prescription drugs into this country from Canada. We're going to allow it. Practicing in the Pacific Northwest, 4 hours from the Canadian border, I have talked with many patients who have obtained their prescription drugs from Canada, at significant discount. I also have a few patients who have purchased drugs cheaply in Mexico. The appeal is obvious, and the logic can be hard to refute. Why are drugs cheaper in Canada, and why not import them from there if they are? The reasons for less expensive Canadian drugs are severalfold. Prescription drugs still on patent are price-controlled in Canada at the wholesale level by the Patented Medicine Prices Review Board (PMPRB), which sets the price of all new patented medications. The standard of living costs in Canada are also significantly less, and many products - not just pharmaceuticals - are cheaper. Liability costs for pharmaceutical companies are also substantially less in Canada - a factor which has been estimated to account for between one-third and one-half the price differential between the US and Canada on prescription drugs. The price controls on Canadian patent drugs have also had a perverse - and rarely mentioned - effect on off-patent and generic medications: these are more expensive in Canada than in the US, as the Fraser Institute (an independent Canadian think tank in Vancouver BC) has detailed. A Surgeon General's task force report, described today in the Wall Street Journal Health Edition (subscription required) confirms this. Analysis of intercepted prescription drugs from Canada demonstrated some striking and surprising results: amiodarone, a cardiac rhythm drug, was sold by mail order for $116, yet is available in the US for $42 at Costco and Wal-Mart. Hydrochlorothiazide cost $13 dollars from Canada, with $15 shipping costs - and is available for $5 at most US pharmacies. Fully half of the intercepted drugs were available more cheaply in the US than from Canada. Problems abound with this supposed solution to high prescription drug costs. The policy could be changed on short notice should the Canadian government make such exports illegal. Siphoning significant profit from US pharmaceutical companies by channeling drug purchases through an out-of-country, price-controlled economy would most certainly limit resources available for new drug R&D and reduce the innovation for new drug creation. And then there is the problem of quality control and potential fraud. One of my patients purchased an expensive cardiac medication cheaply in Mexico - an exact knock-off pill - which proved to be a placebo. Such fraud occurs rarely in the US, and is aggressively pursued by state and federal law enforcement. Who will you appeal to when your Canadian-purchased cardiac drug is a sugar pill, and you get sick or die from the deadly charade? Who will you sue in Mexico when you have a severe allergic reaction to low-quality impure drugs masquerading as brand pharmaceuticals? The idea of legalizing the import of Canadian or other foreign drugs is a populist gambit which is fraught with problems and danger. It is a prescription for our health care best avoided.

US Patent 6645402 - Carbon Electron Emitting Device
Posted on July 28, 2008 in Generic biologicals
On occasion I will have a discussion with someone outside of the field about patents. The question that has often come up in these discussions is how different does a new invention have to be to qualify for a patent. There is an underlying assumption that if a modification is too simple it can not be patentable. I, of course, explain about the "obvious to one of ordinary skill in the art" standard, used in the U.S. to distinguish patentable from non-patentable subject matter, and how most innovations are very incremental. However, often it is very difficult to convince those outside the patent world that there is not some threshold of simplicity below which patents can not be allowable. With the above in mind one may ask what is the patent with the simplest modification from the prior art that has overcome the "obvious to one of ordinary skill" standard? I would submit US Patent 6645402 as a possible candidate for this honor. http://www.freepatentsonline.com/6645402.html Claim 1 reads 1. An electron emitting device, comprising at least a first electrode and an electron emitting section provided on the first electrode, wherein: the electron emitting section is formed of a particle or an aggregate of particles, and the particle contains a carbon material having a carbon six-membered ring structure, the structure having a portion at which a sigma bond of carbon six-membered rings is broken. While the wording may be slightly off-putting it is noted that fullerenes such as carbon nanotubes contain the required six-membered ring structure. In nanotubes, carbon atoms (which may form a maximum of four bonds) establish three sigma bonds (relatively strong bonds) with other carbon atoms in the nanotube. Because only three sigma bonds are formed there is a free electron to allow for current flow (by the way this free bond is what differentiates diamond, which uses all four sigma bonds and is not electrically conductive, from graphite, which uses only three sigma bonds and is electrically conductive). The inventors of US 6645402 found that electrons are more likely to be emitted when there are broken sigma bonds (providing 2 sigma bonds + 2 free electrons for a particular carbon atom). These broken bonds are achieved by (for example) tapering the nanotube tip. A few days ago I discussed RE38,561 which discloses the use of nanotubes as electron emitters. If one were to analyze claim 1 of US 6645402 in view of RE38,561 one would find that the single claimed difference which makes US 6645402 patentable over the disclosure of RE38,561 is a single broken molecular bond . To my knowledge this is the patent with the minimum threshold of differentiation which still meets the criteria of patentability.
LH2, Love It or Hate It?
Posted on July 27, 2008 in Ed pump
My recent commentary on the Space Access Update #112 drew a lot of commentary, including a comment from Henry Vanderbuilt himself. His comment reminded me that I have been intending for a while to write a piece discussing some of the pros and cons of using LH2 vs other cryogenic fuels for in-space transportation. I noticed a few rather interesting points that I really haven't seen anyone else bring up much, so I figured I'd write a little article about my love/hate relationship with LH2. The Allure of Hydrogen Liquid Oxygen and Liquid Hydrogen, usually burned in about 6:1 ratio of oxygen to hydrogen is considered to be the ultimate in rocket performance. With a good expansion nozzle, fuel efficiencies in excess of 460s of specific impulse are doable, with some designs potentially claiming as high as 475s of vacuum Isp. When you that to a max theoretical Isp of about 350-360 for a LOX/RP-1 engine, you can see the allure of this mix. NASA in particular has been very fond of this mixture. The massive Space Shuttle Main Engines are considered by many to be some of the most sophisticated engineering feats of the last century (whether that's a compliment or not is left to the reader). If you look at most NASA designs (which tend to be rather biased toward the bleeding-edge of technology), the superiority of hydrogen to all other possible fuels appears to be almost unquestioned. Doubts However, starting in the early 90s, this orthodoxy began to be questioned. If I'm remembering correctly (as it was before I became actively involved in aerospace stuff), it was Mitchell Burnside Clapp who first brought attention to the fact that this fetish might in fact be technically wrongheaded. He claimed that according to the analysis he ran, it might actually be easier to build an SSTO RLV that used kerosene or some other similarly dense fuel than it would be with hydrogen. Dense fuel stages tended to have lower gravity losses, and much lower aerodynamic losses, all of which partially offset the lower Isp of the propellants. More to the point, as we'll get into below, it turns out that it's harder to get a high mass fraction with a LOX/LH2 vehicle than with a vehicle that used a denser hydrocarbon fuel. [Ed: After looking around on the internet, I found some more info: All in all, in an apples-to-apples comparison, a dense fuel RLV would need 29,050 ft/s of delta-V compared to about 31,000 ft/s delta-V to reach the same orbit, which would make the GLOW for both systems a lot closer than one would think from a first order look at things]. Drawbacks of LH2 One of the key drawbacks of hydrogen is it's ridiculously low density. Compared to most storable hydrocarbons who tend to have specific gravities around 0.7-0.8, hydrogen's specific gravity is a measly 0.07! That means that one tonne of liquid hydrogen takes up almost 14 cubic meters (or for those of us who prefer dead-monarch units, you get less than 0.5lb of the stuff per gallon). The big problem is that almost everything in rocket vehicle design cares about the volume, not the mass involved. Tanks mass scales almost linearly with volume. Pumps pump volume, not mass. Feedlines have to be sized for the volumetric flow rate of the fluid. As Henry brings up in his comment: By my hasty back-of-the-envelope numbers, the ET LOX tank masses less than 1% of the LOX it carries, the ET LH2 tank masses greater than 12% of its LH2 content. Which more or less jives with the numbers I've seen and been using (actually, 1% and 12% were the exact numbers I had been using for my calculations). Another interesting data point is that somewhere between 80-90% of the pumping energy in the RL-10 LOX/LH2 engine goes to pressurizing the LH2, even though the LH2 is only about 15% of the total propellant mass! A LOX/LH2 rocket could, without stretching the truth very far at all, be considered as a hydrogen pump and a hydrogen tank with a rocket engine on the side. Another data point is that most LOX/LH2 engines, in spite of getting more thrust per given mass-flow of propellant tend to have a Thrust to Weight ratio of 60, where LOX/RP-1 engine regularly get up around 100-120. There's another annoying problem with LH2--the stuff is so darn cold. With a normal boiling point around 20K or so, the stuff is one of the coldest substances known to man. Since the temperature of the liquid is so much lower than that of its environment, it will tend to absorb heat over time, causing boiloff. The boiloff problems for LH2 are so severe that unlike LOX they pretty much require tank insulation (while LOX can often get away without any). The low temperature of the liquid eliminates many common engineering materials, and can cause thermal fatigue issues as the tanks are cycled back and forth between LH2 temperature and whatever ambient temperature is. Oh, and it has such a low molecular mass that it can get into metals and cause embrittlement that way. Oh, and it makes sealing tougher. Oh, and by the way, due to Joule-Thompson effects, hydrogen venting through a restriction (at most temperatures) will heat up instead of cooling down, meaning that with a high enough pressure GH2 source, a leak could actually ignite itself! Oh, and it burns with a nearly invisible flame that is several thousand K... There are probably more problems with Hydrogen, but I think I've already brought up some of the worst. So What are the Alternatives? Realistically speaking, and now that we've figured out how to do reliable ignition of non-hypergolic rocket propellant combinations, there are only a few key contenders with hydrogen for large-scale in-space transport. Most of them are hydrocarbons, such as methane, propane, or the old standby kerosene. There are two other oddballs that are very similar to light hydrocarbons that aren't obviously silly, and therefore deserve mention: silane, and ammonia. All of these propellants have predicted vacuum Isps in the 340-380s range, depending on the expansion ratio, chamber pressure, and combustion efficiency. All of them have bulk propellant densities much better than LOX/LH2. Ranging from a bulk density of about 1.03 for LOK/RP-1, down to 0.83 or so for LOX/Methane, as compared to 0.33 or so for LOX/LH2. That means you can get somewhere near 2.5-3x as much propellant into the same volume when compared to LH2. This is important for two things: drylaunch, and tank mass. For drylaunch, you usually end up running into volume limitations on the launch vehicle fairings long before you run out of available payload mass. For example, the Atlas V, 4.5m PLF has about 180 cubic meters of space in its cylindrical section. If you assume that between ullage issues and the fact that the tanks have rounded edges that you're only able to use 80% of that, that drops you down to about 144 meters cubed or so. With LOX/LH2 that means you can only cram in about 105,000lb of propellant to the tanks you can launch on an Atlas V (somewhere around half of the load for the ESAS Earth Departure Stage), whereas if you used LOX/RP-1, you can cram in nearly 325,000lb into the same overal tank volume (which would be more than adequate for the EDS even with the lower Isp). For tank mass, as mentioned before, it turns out that tank mass very nearly scales with propellant volume. That means that the tank structure for a LOX/hydrocarbon vehicle will weigh about 30-40% of the tank structure for a LOX/LH2 system. Another important thing is boiloff. Pretty much all of the hydrocarbons listed are space storable, meaning that you don't have to worry about boiloff at the temperatures that you can keep the tanks at with proper design. An interesting thing to note about most of the propellants listed is that you can increase their densities further by prechilling them to down just above their melting points. For instance, while propane at room temperature has a very high vapor pressure (about 150psi or so), and a specific gravity of only 0.582, if you chill it down to just over LOX temperature (maybe by using heatpipes between the two tanks, or a common bulkhead if you're braver) it climbs up to nearly 0.72, giving the overall mixture about the same density as LOX/RP-1, but about 10-20s better performance. [Ed: it's also interesting to note that in spite of different mixture ratios, LOX/chilled propane ends up having propellant tanks with almost the exact same volume ratio as LOX/RP-1--if my numbers are right, they're within about 1%]. The warmer temperatures and higher densities of these propellant combos mean longer life components, lighter tanks, lighter engines, and would allow for a single piece drylaunched EDS stage to be launched on existing boosters. Not to mention cheaper to design, easier to handle, etc. Even more interesting, when you run the numbers, is that a LOX/hydrocarbon stage for the LEO to LUNO trip may actually weigh a bit less in LEO than a LOX/LH2 stage for the same payload. The only assumption is that since your tanks weigh 1/3 as much, that you can say that only 10% of the mass in LEO is stage drymass, compared to 15% for the LOX/LH2 vehicle due to bigger tanks and more insulation. Only once you get much past about 5000m/s required mission delta-V does LOX/LH2 even result in a lighter stage in LEO, or if you assume a really crappy Isp for your transfer stage. [Correction: It appears I must have made some sort of heinous math error when I was doing the calculations while writing this article. Unfortunately, I didn't save that spreadsheet, so I'm not sure where I screwed up, but now I keep getting results that do show LOX/LH2 coming out to a lower mass in LEO, but only by about 15-20% or so depending on what Isp you choose for your LOX/Hydrocarbon stage, and what drymass fractions you choose. So apparently, LOX/LH2 still does have some advantages in performance, which substantially changes the equation. Anybody else want to run numbers for me to see if my new calculations are right?] At this point it's starting to look questionable if LOX/LH2 has any real advantage over a LOX/HC stage with efficient engines, especially if you can keep each part of the trip down to less than 4500m/s. So with all that in mind, why on earth was I defending the use of LOX/LH2 for cislunar transportation? LH2: What's there to Love? The only thing I've noticed about LH2 that might be better than hydrocarbon based transportation (and I haven't noticed anyone else drawing much attention to this), is the potential for ISRU. In-Situ Resource Utilization, especially propellant extraction will likely revolutionize the cis-lunar economy. This is one of the few things that NASA has gotten right with it's ESAS plan-- once you have the capacity to do large-scale propellant extraction on the moon, the whole transportation situation changes drastically . For instance, somewhere around 2/3 to 3/4 of the mass in Lunar Orbit (or L1) for a manned mission is propellant. Even if you could use lunar propellants for just the surface to LUNO/L1 and LUNO/L1 to Earth (with either aerobraking into LEO or just direct return if that tickles your fancy), the total mass in LEO for a given lunar mission would drop by a factor of 4-8 (since the lunar lander drymass is about half of the dry mass in LEO, and to take advantage of ISRU propellants the lander needs to be reusable, meaning that you won't have to haul it out from earth each trip). There's one big problem. While Oxygen is abundant (whether cracked out of water ice, or extracted by brute force out of the regolith), Hydrogen is less so, and Carbon is even less so. Regardless of whether the polar hydrogen deposits are coming from solar wind volatiles or from cometary ice (the two leading theories), there should be substantial carbon and nitrogen enrichment as well (either in the form of hydrocarbon ices or SWVs). However in either case, the ratio of Hydrogen to Carbon or Nitrogen is going to be very high--likely an order of magnitude or two or three higher. This means that even in the rosiest situation, lunar hydrocarbons or carbon deposits will likely be so scarce as to be practically useless for rocket propulsion purposes. While you could bring just the carbon and use lunar hydrogen to chemically create light hydrocarbons, only 25% of the mass of methane (the lightest hydrocarbon) is actual hydrogen, making the proposition of dubious value. Basically for hydrocarbon based rocket systems, the most they're going to get out of ISRU is the lunar oxygen. And that is the second problem. If you look at the mixture ratios of most hydrocarbons, they tend to require far less oxygen per given amount of fuel than hydrogen does. For LOX/LH2, the ratio is usually 6:1, whereas for LOX/Methane it is only 3.4:1, 3.1:1 for LOX/propane, and only 2.7:1 for LOX/RP-1. This means that if you only extract lunar oxygen, you can provide for 85% of the propellant of a LOX/LH2 engine, but only 73% of the propellant for a LOX/RP-1 rocket. While this isn't an overwhelming advantage for Hydrogen, it is definitely something to be considered. Ramifications? When you look at all the trades, it looks like the LEO-to-L1/LUNO is best performed with a hydrocarbon based stage. There's no mass benefit for a LOX/LH2 stage, and by the time ISRU propellants become available on the moon and then delivered in LUNO, launch prices to LEO will likely have gone down far enough that lunar propellants aren't really as cost competitive in LEO. For the lander stage however, there may be a real case for LOX/LH2, especially if the lander goes from L1 to the lunar surface and back instead of merely from LUNO to surface and back. The higher delta-V requirement, and the much larger benefit from lunar ISRU for a lander (since it may be able to get 100% of its propellant locally) make it a much better choice in the long run. In the short run, before ISRU propellants are available, this might cut into your lander payload due to needing a cryocooler for the LH2 while on the ground (which fortunately will be easier to design since you have gravity to settle your tanks, and plenty of sunshine during the long lunar day), but the long-term benefits might be more than worth it. Ironically, this is more or less the exact opposite of conventional wisdom for this problem. [Ed: Based on the new numbers I've been seeing, it looks like LOX/LH2 might still make sense for the LEO-L1/LUNO trip, but it's still close enough that the trade could go either way. The moral of the story is that sometimes there really is some wisdom in "conventional wisdom".] Thoughts, comments, flames?

Scotland has a perfectly goood EPR system you know!
Posted on July 12, 2008 in Prescriptions
The English NHS has for a number of years been attempting to implement an Electronic Patient Record (EPR) and an Electronic Health Record (EHR). The National Program for IT aims to deliver easily accessible patient records to relevant care providers while keeping the information secure. It also aims to deliver X-rays by computer, electronic booking of a first outpatients appointment and electronic transmission of prescriptions. (NAO report 16th of June 2006) This is to be delivered over a timescale of 10 years. The NAO claims that areas of this program are on track. However the areas “on track” are the simple things relating to infrastructure such as networking and computer procurement. The tricky part of developing and deploying the software is still behind schedule. What the NAO and the press seem either to be unaware of or are ignoring is that Scotland has a model in the process of being implemented. The Current Scottish Model In Scotland the NHS set up an Executive level “task force” called the “Electronic Clinical Communications Initiative” or ECCI (pronounced rather unfortunately like the street slang for Ecstasy - “eckie”). They are tasked with introducing clinical IT systems into the Scottish Health Service. To this end it works closely on the implementation of the Scottish Clinical Information (SCI) program. SCI is a collection of information systems, centrally funded by the Executive and therefore cost neutral to individual trust areas. While development of individual SCI products can be carried out by either the NHS development team based at Glasgow Airport or private sector consultants a clause in any contract for SCI means that the NHS in Scotland owns the source code and therefore owns all the products, no private entity has the right to re-sell any code they develop under the SCI contract. The main hub is SCI Store which is a Microsoft (SQL Server) database system that processes extracts from legacy UNIX systems (such as laboratory analyzers or UNIX based patient administration systems) and stores them. Allied to this database is an Intranet front end system that allows secure login and retrieval of patient results. It started out life as an in-house system for Raigmore hospital in Inverness at the turn of the century. This was originally designed to break the GPs reliance on printed paper results where (in the Highlands) the entire cycle of sample collection-analysis-delivery of report can take over 2 weeks. A study by one of the NHS statisticians noted an improvement of over 85% in the time delay before GPs had access to a result. Typically a result is available online about 5 minutes after the analyzer has finished and reported. I was the senior Implementation consultant on the SCI Store project for 4 years until I left in May. Store exposes a number of “web services”. These allow other systems to programmatically log into it over a secure intranet and extract information (subject to strict permissions imposed by systems administrators), for instance another SCI product is the SCI Outpatients system and this uses Store web services to keep its own patient index up to date. Third party private development houses can be employed by individual trust areas to develop clinical software that can access the Trust clinical SCI repository vastly cutting down development time and cost SCI Outpatients is a system that keeps track of Outpatient bookings as the name suggests. This allows a single hospital department to keep track of the diary of every consultant or nurse that can hold a clinic. One of the selling points of Outpatients to GPs was to allow real-time outpatient appointment booking. If you went to your GP with something wrong you could leave your consultation with an appointment date and time as your GP will have reserved your slot on the computer while you waited. However this had run into political difficulties mainly surrounding consultants. Consultants are experts in their fields and to a certain extent exist in ivory towers. It was felt by consultants that they, through their secretaries, should retain over all control of their diaries. To let a mere GP book slots may ruin a tee-off time they had planned. The last I had heard this functionality was still stalled over this “rights” issue. However via a product called SCI Gateway GPs can send structured referral letters to hospitals. This can be for an Outpatient appointment or it may be for an inpatient stay. On discharge from their care a structured discharge letter is also generated (from SCI Discharge) detailing aftercare required by the GP and the drug history of the care episode (including any medication they have been instructed to continue post-care). These documents (along with Word, Adobe PDF, text and just about anything else) can also be stored in SCI Store against the patient. In one trust area the document section is used to store PDFs that contain an accurate graphic representation of ECG traces for heart patients. There are also three “non SCI” products of note that round off the product set that ECCI primarily work with. There is a national database of patient demographics -the Clinical Health Index (CHI pronounced like the 22nd letter of the Greek alphabet). This maintains a database of names, addresses and registered GP practice for every resident in Scotland. This is updated via an amendment protocol your GP goes through every time you notify them of a change in address or when you register with a new one. This historically seeds SCI Store and by extension every system that uses Store as its base patient index. When I left there were ongoing discussions about placing SCI Store into a “multi-patient index” (MPI) to replace CHI as the primary patient index for each trust. 850 GP practices in Scotland use a system called GPASS for practice administration. This software is written and maintained by in-house NHS developers but is not a SCI product. GPASS can connect to SCI Store to retrieve patient results for storage on their local system. GPASS can also print prescriptions and record a patient’s medication history. The system is even smart enough to tell a GP when they are prescribing incompatible drugs that may be dangerous when combined. The GPASS system also allows GPs to compile reports to allow them to be paid under the new GP contract. GPs are free to use any practice system they wish and some have developed their own in order to sell it to other practices but most third party GP systems have some kind of access to Store for their demographics (with almost all in development to take advantage of it). Finally there is the Emergency Care Summary (ECS). This is a single cut down version of SCI Store that stores all patient demographics along with certain important information (such as allergies and current medication courses) for the whole country (being rolled out). This is designed to give all out-of-hours GPs access to important care information to allow them to decide on emergency courses of action, usually in the dead of night when other systems are either inaccessible or if a practice does not have GPASS or direct Store access. Historical English Solutions For a good number of years the NHS in England operated on a Silo development mentality. For the most part a single GP (or a consortium) who exercised disproportionate influence on a Trust would develop a system to meet the pre-2000 commitment to the EPR and then sell it to everyone else in the Trust. Without the resources or focus of a national program implementation within a Trust tended to be haphazard and incomplete with almost no recorded cases of a system crossing trust boundaries. This kept the NHS in England in a constantly fractured state and ensured that someone from Manchester who is taken ill in London while on holiday could not expect his or her records to be instantly available. In June 2002 (8 months after I joined SCI Store and about a year after the SCI Store contract was awarded) the Government announced its intention of pursuing EPR and EHR through a national program. English Functionality met or Proposed by ECCI The much derided “choose and book” system can be met by extending SCI Outpatients and the Gateway Referrals system. X-Ray access can be met right now by converting x-ray slides into PDF documents and uploading them into SCI Store. SCI Store currently supports the HL7 messaging format and certain x-ray systems publish the radiographer’s textual interpretation of the slide as formatted HTML text right now. Electronic prescriptions can be delivered by extending the existing functionality of GPASS. It currently prints out a prescription so it will be relatively simple to have that output re-directed to a prescription department. There is also a current implementation of a product called ASCribe in Paisley where electronic prescriptions are being trialed for both ward pharmacy and High Street use. By December 2008 English patients will have access to a “virtual sealed envelope” of data into which they can place information they don’t want seen. SCI Store implemented this in February 2006 with version 2.2 of the software in compliance with the Data Protection Act. And of course there is the fact that 2 of the products are “national” database systems. Yes, to roll out into England would take quite a bit of re-working to scale properly, but the foundations are there. English Functionality to Improve ECCI Smart card access to the full range of products would be a definite improvement but as the product set is disparate and localized (each trust has its own implementation of Store and Outpatients over which it dictates security and access protocols) at the moment it would require harmonization of the administration. Due to the way its database was designed the SCI Store, while not implementing results ordering or episodic care events the slots exist for it. Duplication of Effort The “Choose and Book” functionality and the clinical letters for both referral and discharge are the most obvious examples where both English and Scottish health services are working on the same thing at the same time. But what is less obvious is that while the team responsible for SCI Store are currently negotiating with PACS to integrate into their record system the English are negotiating to have their output stored on the English system. Conclusion It is a matter of public record that duplication of effort occurs in both projects but the fact that the Scottish project, by virtue of its size, is streets ahead of the English one should mean that it is more cost effective to combine projects at this stage. Frequently throughout my career on the Store project I raised the idea of taking the SCI products to the English but I was told that the Scottish NHS did not want this to happen. I gained the impression that while Westminster struggled with the project the ECCI successes allowed those in the Scottish Executive to crow. They are using these two projects in a game of career one-upmanship. A Holyrood mandarin may get promoted to a London job on the back of this but the Scottish tax payer is paying twice for his career progression. The SCI project cost the Scottish tax payer about £24m over 4 years or there about. The English model is going to cost every tax payer in the UK £6bn. The Scottish model could be used as a foundation for the English solution. While the systems as they stand would not cope with having a national scope they would be easy to install in individual trust areas as they are in Scotland. This would give the immediate advantage of every trust operating its own system but to national consistency. Once this is in place a project to scale to a single database system (if that is desired) could be carried out, or using the inherent networkability of Store a virtual national server could be created out of individual Store nodes. The rest of the product set could be deployed in a similar fashion. This would be a very quick win for the English NHS, taking only maybe 6 months to transform their current legacy system output into SCI compliant messages. Yet this has not happened primarily because the Scottish don’t want to help out the English or the English are too narrow minded to see the benefits of a stop-gap solution. Even in the media this option appears to have passed people by. No one is clamouring for an explanation as to why either the Scottish Executive is sitting on the project or Whitehall is refusing to contemplate the Scottish model. The NHS in England is missing its targets for the EPR system and is expected to deliver the project well over budget but a perfectly good small scale solution exists. And its closest implementation is Melrose General Hospital. Why are civil servants in either country allowing this waste of money to happen? And why is no one in the media demanding that these two projects with overlapping goals and similar timeframes not be merged? Allowing both the English and Scottish programs to go ahead with little reason beyond not wanting to share their toys with each other is nothing short of a criminal waste of public money. Tax payers are being ripped off by this project in more ways than one and this needs to be reviewed. Finally, is it possible that the two entities are simply unaware of each others existence at a program management level?
