    The sham surgeries aren't done by fraudulent physicians. There have been studies done for knee pain, where patients are randomly selected for traditional arthroscopy versus a sham surgery, where arthroscopy style skin incisions are created, and then sewn shut. When the patient awakens, they don't know if they had actual surgery or not. This is the study's design, and all patients in the study agree to the randomization process. This is quite different that a surgeon "pretending" to do surgery to bill patient. That, of course, would be fraudulent, unethical, and illegal.

  3. One doctor's perspective on Should Organic Chemistry Be a Premed Requirement? · · Score: 1

    I'm a family physician, graduated med school in 2001, been in practice since 2004. First, I loved O-Chem, so I'm probably odd. General chem was okay, but it was a much bigger weed-out class. It felt like more rote memorization.

    O-chem was interesting and fun, because the reactions made intuitive sense. Once you understood why the electrons flowed the way they did, you didn't have to memorize the Clemenson reaction or the Grignard reaction, you just "got" why they worked.

    If you don't understand O-chem, you really will never get biochemistry. Although med students complain about first-year biochem, it's essential. When I decide to prescribe Crestor to someone for their hyperlipidemia, I really ought to know how Crestor works. Specifically, what does Hmg-CoA reductase do, where does it work in the cholesterol synthesis cycle, and why would it be good to take Crestor. Instead, you have doctors or PA/NPs who simply prescribe Crestor because the last drug rep was cute, rather than understanding the underlying pathophysiology.

    To the posters who've noted that demand is outstripping supplies of doctors: I agree that we need to lower the barriers to producing more doctors. But, dumbing down pre-med isn't the answer. Moderating the cost of medical education could go a long way. There's a tremendous shortage of Family Physicians and general Internists. But if you're a 4th year med student looking at $250K of student loan debt, you've got to consider your ability to repay it. From an purely economic standpoint, why would I do a 3 year primary care residency and make $170K/year, when I could do a 4 year anesthesia residency and make $400K/year.

    Since I am a Family Doc, there must be more reasons than just economics (or perhaps I couldn't get into an anesthesia residency ;-). I dunno. I always planned on Family Medicine.

    Back to the original question. Next time you get a drug sample, unfold the little packet of paper that folds out to the size of a large map. That's the product insert. Look at the very top. There's a picture of the chemical structure, and the actual name of the molecule.

    Nice cheapshot there, AC. My yacht is a 1999 Dodge Intrepid with 105,000 miles.

    I've worked in the VA system in med school and residency. To be fair, there's a lot to like. You can go to any VA in the country and your doc can pull up your entire chart. That's a huge deal.

    However, one can't compare the VA to Medicare in an apples-to-apples comparison. The VA CAN bargain with drug companies. They get tremendous price concessions from the companies. Medicare is prohibited by law to do such things. As long as you're prescribing the drugs on the VA preferred list, costs are contained pretty well, and the patients have relatively cheap copays.

    If you want to do anything outside the approved list, heaven help you and your patient. I've spent hours trying to get Prevacid approved for a patient who had failed Aciphex therapy (preferred). They never approved it. The VA is not set up well for emergency care. Sure, they have an ER. But it's usually a major fight to get my patient having a heart attack transferred to the VA ER.

    I don't dispute that the VA is more efficient that commercial insurance companies. After all, the VA, hopefully, doesn't have bottom line and shareholder interests as its primary goal.

    If you're an optimist, you can view the VA as a good example of how government might do things right.

    I'm in favor of a national health care system, at least in principle. However, I don't think the political environment in the US will ever allow it.

    We could save billions on pharmaceuticals alone if Medicare was allowed to bargain with the drug companies.

    Certainly, these are excellent points. You're quite correct that there are ethical dilemmas when business and medicine cross. I would love to be paid a reasonable salary (you can debate what is reasonable) and not worry about the business side of things. However, I've got staff to pay, supplies to buy, rent and utilities, etc., etc., etc. Only after these expenses are paid do I take anything home.

    You can make the same argument about health insurance. There's an ethical conflict of interest at work when you take people's money (insurance premiums) and contract to pay for their health care costs. Since you already have their money in hand, you, the insurer, have every incentive to deny or delay payment whenever possible. The longer you do this, the more money and interest you make. If you deny coverage for that MRI, that's another $1500 that stays with your company, instead of going to the radiologist or the hospital.

    Of course, I have the incentive to perform more procedures on a patient. The more I perform, the more fees I generate (or so the theory goes). Or, you can pay doctors a flat fee per month per patient (capitation). Now, the doctor has every incentive to not do anything extra for the patient, because they won't get paid any more. No matter which side you choose, there are always potential conflicts of interest. The goal is to develop a system or framework where these conflicts are minimized.

    For what it's worth, most doctors are very uncomfortable thinking of themselves as businessmen/women. We are not comfortable talking about fees with patients, and you feel like you're lowering yourself to the used car salesman level. But, you've gotta stay in the black, or the clinic closes.

  9. My thoughts as a practicing Family Physician on Can Technology Fix the Health Care System? · · Score: 1

    I'm a Family Physician in rural Utah. There are several points in the article and posts worth commenting on:

    First, technology will help, but certainly not fix the system. Yes, there are inefficiencies. My clinic, with 3 MDs, has about 20,000 total charts. Of those, probably 5-10,000 are active patients. The cost and time involved to maintain, file, refile, and add to these charts is enormous. Having said that, we are stilling making a somewhat greater income than the average family doc. We switched to an electronic medical record system in November 2006. It has saved us time spent in chasing charts and making copies. But, we had to upgrade out entire office network AND buy the EMR system. That's about $120K to start, and about 15-20%/year in maintenance fees. So, we're more efficient in many ways, but it's certainly not making us more money. I'm now more efficient and I make less money. I would never, ever go back to paper charts, but most docs won't pony up the $40K/doc for a system that costs them more money. If it comes down to money or efficiency, efficiency be damned is the mindset. And before everyone starts complaining about overpaid doctors, please realize that nearly all businesses would make the same decision.

    Second, the US spends far too much money on the ends of life. Okay, most of us are willing to allow our taxes to go towards saving pre-term babies. However, is it really worth spending another $200-500K on pacemaker and cardiac bypass surgery for an 85 year old man with end-stage emphysema, congestive heart failure, renal failure, and alzheimer's dementia? No, it's not. We need to tell Americans, "Sorry. There's not money available to pay for that." We could immunize thousands of kids for the cost of that pacemaker and surgery. But Americans currently demand "the best healthcare system in the world". In their minds, it's worth "any cost" to spend another week of quality time with Grandma before she inevitably dies.

    Third, health insurance and copays obscure the real cost of healthcare. If the patient knows that he's going to pay $20 for his office copay, he doesn't really care if the doctor submits a $60 or a $120 charge to insurance. There's no incentive to search for a lower price. If you're on a high deductible plan, that person with usually try to bargain with the physician. At the least, they'll question why I might bill a level 3 office visit charge vs. a level 4 office visit charge.

    Similarly, patients don't have any incentive to use a cheaper, but similarly effective medication. As long as my copay is $25, why should I care whether I'm on Effexor XR ($140/month) or generic Celexa ($10/month).

    Fourth, the process of submitting claims to insurance is encrusted with bureaucracy at every level. Each company has you submit the claim to a different address, with different information and codes. Their claims software is designed to reject certain claims immediately. Now I can file an appeal and often get them paid, but that may cost $20-50 in staff time. If it's a $40 claim, it's not worth it-and they know it.

    I'd like to think that a government mandated, standardized submission process would be more efficient. But even under heavy sedation, I would never believe that the government that brought us Medicare, Medicaid, and the VA could possibly get it right.

    Okay, take your best shots ;-)

As you pointed out, if (some drug company) invents a real cure for AIDs, they will make a bazillion dollars and their stockholders will be able to hire Trump and Gates as their shoe-shine boys.

    As a researcher, I imagine that you have personal, social, and ethical reasons to motivate you to find a new treatment for major diseases. Good for you. (that's not sarcasm-I really mean that).

    However, the marketing and PR departments and the army of drug reps out there present a different perspective. There's not a day that goes by that a drug rep doesn't try to convince me that I should be prescribing Diovan/Cozaar/Benicar/Micardis, etc., for blood pressure instead of Lisinopril. Diovan and friends are a class of drugs called ARBs that have are very effective for lowering blood pressure and thereby lowering the risk of stroke and renal damage. However, Lisinopril, belonging to an older class of drugs called ACE inhibitors, is just as effective, and it's dirt cheap. The irony is that Lisinopril was once marketed like crazy as THE go-to drug for hypertension. But once it's off patent and generics are available, you never hear about it again. The implication is that if I want to be an up-to-date physician, I'd be prescribing the latest and greatest. Never mind that it doesn't work any better.

    The most recent, blatant, insulting example was Zocor. For years, Zocor was pushed as god's gift to lowering cholesterol. And yes, it has some great studies showing decreases in heart attacks. However, Zocor became available as a generic this year. I had two visits from the SAME Merck rep about 3 months apart. At the first visit, the message was, "Zocor. The drug of choice. Blah, blah, blah. Nothing new here."

    At the second visit by the exact same rep, she tells me, "Well, you might use Zocor for your patients who need mild cholesterol lowering. But for patients needing robust lowering, you really should avoid Zocor and prescribe VYTORIN (trumpets sound in the background). Coincidentally, Vytorin is simply Zocor plus Zetia combined into one pill. Wow!! That's some great innovation there! At least the stockholders would see it that way.

    This happens again and again with me-too drugs. Claritin and Clarinex? Floxin and Levaquin? Prilosec and Nexium? Celexa and Lexapro? Albuterol and Xoponex? The second is simply one isomer of the first, which is a racemic mixture. These drugs are already invented and patented. Why should separating a racemic mixture justify a new patent? It's absurd. It may be technically challenging, but not patent-worthy.

    As for the HPV vaccine: it's a great shot series, but Merck isn't selling it cheap. I understand that they've got to cover R&D costs, but if they were as altruistic as they'd have us believe, they'd be giving it out as cheaply as possible.

    Perhaps if the NIH were probably funded and could support large, ongoing studies, we'd see some real breakthoughs in new drugs. As long as pharmaceutical companies foot the bill, they will always take the easier route of slightly modifying an existing drug, re-patenting (is that a word?) the "new" drug, and selling it just barely below the current market leader. They may stumble onto new, innovative compounds that are actually a breakthrough, but as the article points out, this is the exception, not the rule.

  12. Nice idea, but missing the bigger errors on Surgical Tools to Include RFID · · Score: 1

    I notice that TFA is actually about sponges. As many previous posts have mentioned, these are much harder to detect when they've been left in surgery. Here's my perspective:

    I'm a physician and the most common major surgeries I perform are C-Sections (I've done two in the last 36 hours, BTW). As already noted, the nurses do sponge, needle, and blade counts before the surgery, and they count more than once, and two nurses participate. Each surgery packet has a standard number of certain instruments, and these counts are also verified.

    During the surgery, the surgeons obviously use up a fair number of sponges. As the sponges get bloody, the scrub nurse takes them from the surgeon and hands him/her a new one. The bloody sponges are placed in groups (usually of five) on a sticky mat on the floor (like flypaper), and the circulating nurse keeps a running total. As the surgery nears conclusion (for example, I've finished sewing up the uterus, but not closed the abdomen), the nurses start a sponge, needle, and blade count. If it's not correct, they count again, and again. Unless the surgery is at a critical stage, the surgeon(s) will stop and look everywhere in the surgical area, in the folds of the drapes, etc., until the missing item is found. In the case of sponges, they're usually hidden in a drape fold, or two bloody sponges are stuck together and counted as one. If a blade or needle can't be found, the portable X-Ray machine is brought in and the patient is X-rayed to make sure nothing is in the surgical field.

    Only the most callous, stupid, and arrogant surgeon would knowingly say, "Oh, I'm sure you miscounted all six times. Lets close up anyway."

    These mistakes are bad and avoidable, but they're certainly not the most common. It makes a big headline and lawyers start to salivate like Pavlov's dog when they hear them. But, wrong patient/wrong surgery/wrong side/sponge-left-inside events are much less common than other errors. For example, if we (the medical profession) could eliminate medication errors (wrong dose, wrong drug, wrong time, wrong patient, allergies), we would drastically reduce the number of errors and patient injuries and deaths.

    This is an interesting technology, but it's going to cost an inordinate amount of money. I think it would be better spent trying to reduce or eliminate the most common errors first.

    Just my 2 cents. Of course, I could be wrong (with apologies to Dennis Miller).

    First, I think it's great that the researchers have demonstrated a potential way to identify pre-clinical type I diabetes. If these patients could be easily identified and the pathologic process halted or reversed, this would be one of the greatest feats ever accomplished in medicine.

    However, this approach has several problems. Another poster has already mentioned that health insurance companies could start denying coverage to kids(and adults) who don't have diabetes, but might get it. If you're a health plan administrator, diabetes is a very, very expensive disease and you want to avoid these patients.

    (Whether health insurance companies should even be in the business to make a profit is a topic for another debate. Short answer: It's absolutely wrong.)

    More importantly, who do you screen with MRI? Do you screen every child at age 5 (or another pre-defined age)? Do you only screen them once?

I have a 20 year old patient who was just diagnosed with type I after the birth of her first child. I also had a medical school classmate who was diagnosed while in his residency.

    Once you've decided who you'll screen and at what age and interval, how do you pay for it? This cannot be ignored. An abdominal MRI can cost $1-3,000, and you often need to sedate patients because it's quite claustrophobic. If you were to screen every child only once, the cost would skyrocket into billions of dollars almost immediately.

You could think of it as a mutated Nintendo controller. After performing a certain number of scopes, you can intuitively guide the scope down the tunnel without thinking about the controls, just like a Nintendo's control pad.
