I think everyone in this space has been way off base as to what the problem is with FDA and Congress wanting to investigate the DTC Genomics companies.
The whole mindset is wrong.
What I hear from this debate is "It's my data, mine, mine, mine. Gimmee, Gimmee, you can't keep me from my data Big Brother!"
From Mr Goetz's Blog
"The controversy seems to have stirred the FDA to assert its authority – and that of physicians – over any and all medical metrics."
"To me, getting access to this information is a civil rights issue. It’s our data."
This is a straw man argument that has been set up to make regulating these companies seem unseemly and an invasion of privacy.
IT IS A DEAD WRONG ARGUMENT and I will not stand for it being perpetuated anymore.
This is not about getting access to your data.
Fine, you want a whole genome, go get it!
The FDA is not asking should people be able to go out and buy this. It is asking several other questions.
1. Is Interpretation of biometric data considered medicine?
The answer here is certainly confusing. I think it rests solely with intent.
Do you intend to tell someone something about a disease they now have based on this biometric data that you analyzed?
If the answer is yes, that is viewed legally and medically as a diagnosis.
Which ultimately I think is medicine and falls under medical regulations.
2. Is DTCG analyzing biometric data and intending to give an interpretation of that data which indicates a disease a person has?
It depends on what you define disease as.
Most legal experts defer to the International Classification of Diseases
3. Should we regulate a system which has not given indication of their quality control if they are indeed intending to provide medical diagnosis?
4. Are these methods of obtaining human samples to derive biometric data for the intent of analyzing and providing information about disease considered medical devices?
This is precisely the argument and precisely what Congress and the FDA are trying to define.
So stop acting like a bunch of little kids running around because someone took your kool aid away!
If I hear another, "It's my data" whine again I will scream.
This is not about restricting access to biometric data.
Which by the way, some states do already.
Is an EKG biometric data? What about a cholesterol?
Probably, no one is stopping you from going out and buying a machine to obtain this data yourself.
But any doctor will tell you, it is the interpretation that can vary widely. As demonstrated by the multiple interpretations that Venter et.al complained about
What they are intending to do is to prevent a third party from having NO ONE to answer to when providing interpretation of that very SAME biometric data.
The Sherpa Says: Regulation here will most definitely not stifle innovation as bad as a consumer death or class action lawsuit or lack of trust from consumers because of the aforementioned.

Tell Me, How do you feel now? Sherpa's RX


One thing is for sure. In a recent poll of members of the AMA, granted a pretty skewed poll as tons of AMA members cut up their cards this year........random sample of 6000 physicians from the American Medical Association (AMA) Physician Masterfile, which includes current data on all U.S. physicians.
Excluded were, residents and doctors in US territories. From this data in the New England Journal of Medicine, Keyhani et al found some interesting things. The biggest of these is that a majority of physicians are for a governmental option WITH private options.
Not a surprise, this is what ALREADY EXISTS.
From the study......
"Survey respondents were asked to indicate which of three options for expanding health insurance coverage they would most strongly support:
1. public and private options, providing people younger than 65 years of age the choice of enrolling in a new public health insurance plan (like Medicare) or in private plans
2. private options only, providing people with tax credits or subsidies, if they have low income, to buy private insurance coverage, without creating a new public plan.
3. a public option only, eliminating private insurance and covering everyone through a single public plan like Medicare.
We also assessed the level of physician support for a proposal that would enable adults between the ages of 55 and 64 years to buy into the current Medicare program — a strategy that the Senate Finance Committee has proposed."
But what pisses me off about the article is how it is written....take a listen....
"Physicians in every census region showed majority support for a public option, with percentages in favor ranging from 58.9% in the South to 69.7% in the Northeast. Practice owners were less likely than nonowners to support a public option (59.7% vs. 67.1%, P<0.001),>majority still supported it."
No caveats for the fact that DOCTORS ONLY SUPPORT A PUBLIC OPTION IFF there exists a private industry as well.
What these jokers don't say is precisely that point. Which is why, the press will publish "A majority of doctors support a Public Plan" which may sound like they support single payer.....
They don't. In fact, 3 times as many support a private only plan than a public only plan!!!!
They do acknowledge limitations
"Some limitations of our study deserve comment. First, our response rate was 43.2%, which is modest, though typical of the most recent national physician surveys and surveys in general.
There were no significant differences between survey respondents and nonrespondents in important characteristics, such as specialty, practice location, and practice type.
Second, physicians’ opinions about strategies for expanding health insurance coverage may have evolved during the period of data collection, given the intensive press coverage of the issues."
But in the end, they never, ever mention the fact that a near THIRD of physicians support a private ONLY system and that this number is 3 times the physicians who support a government ONLY plan like Canada or the UK. Thus placing those progressives who demand such, clearly outside of the mainstream of most physicians.....
The only true way to save costs is to start using science and personalized medicine. You will not save costs by covering more people. In fact, I argue that there is no science which truly extols the benefit of enhanced coverage. What should be enhanced is catastrophic coverage.
What bankrupts people? Catastrophe, not a URI.
If you want to nationalize/universalize coverage, stick with catastrophic care. That would make sure everyone was covered when HUGE bills hit.
I am certain this plan would be extremely useful. Enroll everyone in this system and pay out when catastrophe strikes. It works for life insurance. Leave the small time players alone and focus on hospitalization costs, etc.
Continue funding HPSA and increase the loan repayment to 300k over 3 years rather than 85 over 3 years. Watch the doctors come then.......
Give tax subsidies for people who pay for URIs etc or traditional health insurance, which now should cost less as the government/taxpayer absorbs the catastrophic costs.........
That should keep everyone covered and help out with the uninsured. We all know that the major cost to hopsitals is the "self pay" patient with disseminated echinococcus or HIV or esophageal cancer or heart attack.
As for the government and medicare, if you just had a huge boost in revenue by new people coming on board for catastrophic care (To be read as, not pay out for most, and pay out later for some) you could help that insolvency thingy........
The Sherpa Says: Personalized Medicine is a key, rational thinking is the LOCK! I know, my wife just had an ER visit, the hospital charged 6168.00 USD, the insurance paid 800 USD. If she didn't have an insurer protecting her from gouging, she would have had to pay 6168.00 USD. I see it both ways....

Something off my chest........Health care will never be fixed by Lawyers

I rant and rave about genomics and about hyping of genetic tests but today I have a bigger issue. That issue is plain and simple.
Healthcare is FCUk3D up.
I run a successful personalized medicine practice, just recently we started taking health insurance. The demands from handling billing and copays from insurers AND medicaid has not been that cumbersome. Why? We only see 10 patients per doctor per day.
When you start seeing more than that it creates all sorts of problems.
Like manpower requirements that start to exceed 100-200k per doctor.......
If you have less doctors for more patients, the equation is simple.
Rationing of physician care.
That is what will happen when you cut 400 million dollars of Medicare money. Oh wait, I mean 500 BILLION dollars......
Do I think that the Lawyer serving in congress will ever solve those problems?
No.
Do I think that the very few doctors in congress will fix this problem?
No.
But trust me, there are way more lawyers than doctors in Congress, so I am extremely doubtful.
No Offense GenomicsLawyer.......
Why?
They are not the people who are experiencing the problems.
Maybe the doctors were, but they aren't now.
The solution will come from doctors/nurses/patients who are involved in the system already...... currently.......
To think otherwise is foolish.
And to drown out the protesters, intimidate them and hide from town halls is also foolish.
Both parties in this argument are dead wrong.
They are having the wrong argument.
The average primary care doctor gets paid about the same as they did 10 years ago. Does that make sense?
Costs go up. Rent Goes up. Medical Supplies cost more. And insurance pays less and less, Including Medicare, who pays routinely 1/2 to 1/3 of what private insurers pay.
As a doctor, Don't like what you get paid? Switch Insurers.
But you won't be able to do that under a universal plan.
As a patient? Don't like what your insurance paid for? Switch insurers. Pretty simple, unless of course you have preexisting conditions.......
The system is a mess, not because of what we pay doctors or hospitals or whoever.
The system is a mess because there are a whole lot of sick people out there......More sick people than healthcare practitioners equals shortage of attention.
Shortage of attention leads to worse care and more labs and more procedures. Shortage of attention leads to increased malpractice costs, risks and fears...... Want to fix the system?
Encourage more doctors to go into primary care, make their liability risks less, create technology so that they can "fire" their overhead this will create increased revenues for doctors without raising pay.
But please, don't ration care because we are too busy and too risk averse to do it on our own.
Enable the professionals to do it by giving them time to think about their patients...... This system will never get fixed by lawyers.......never.
Medicine is a thinking man/woman's game, not a sweatshop.....why ask us to run sweatshops? The American people deserve better than that......
The Sherpa Says: What good is personalized medicine if the doctor can't take the time to personalize it for the patients??? You tell me.

I'm All for Change, But this?

I hope you can get a deep understanding of how absolutely and completely worse off we will be with this complicated system. You can say, "well can't the US government track submarines underwater while also tracking missles overhead and STILL collect taxes?" They can, but this is even more complex. Listen, it would be nice to have a cheaper Not For Profit system out there to pay for care.
Remember, having access to health insurance, is NOT having access to healthcare.......
It's having access to health insurance. I don't know if anyone reads Investors Business Daily, I do and on Wednesday I read something which almost made me $h!t my pants. The House bill went public all 1018 pages of it.....
On Page 16 there is something very, very scary on it.........
From IBD (Not to be confused with Crohn's Disease)
By INVESTOR'S BUSINESS DAILY | Posted Wednesday, July 15, 2009 4:20 PM PT
Congress: It didn't take long to run into an "uh-oh" moment when reading the House's "Health care for all Americans" bill. Right there on Page 16 is a provision making individual private medical insurance illegal.
IBD Exclusive Series: Government-Run Healthcare: A Prescription For Failure
When we first saw the paragraph Tuesday, just after the 1,018-page document was released, we thought we surely must be misreading it. So we sought help from the House Ways and Means Committee.
It turns out we were right: The provision would indeed outlaw individual private coverage. Under the Orwellian header of "Protecting The Choice To Keep Current Coverage," the "Limitation On New Enrollment" section of the bill clearly states:
"Except as provided in this paragraph, the individual health insurance issuer offering such coverage does not enroll any individual in such coverage if the first effective date of coverage is on or after the first day" of the year the legislation becomes law.
So we can all keep our coverage, just as promised — with, of course, exceptions: Those who currently have private individual coverage won't be able to change it. Nor will those who leave a company to work for themselves be free to buy individual plans from private carriers.
From the beginning, opponents of the public option plan have warned that if the government gets into the business of offering subsidized health insurance coverage, the private insurance market will wither. Drawn by a public option that will be 30% to 40% cheaper than their current premiums because taxpayers will be funding it, employers will gladly scrap their private plans and go with Washington's coverage.
The nonpartisan Lewin Group estimated in April that 120 million or more Americans could lose their group coverage at work and end up in such a program. That would leave private carriers with 50 million or fewer customers. This could cause the market to, as Lewin Vice President John Sheils put it, "fizzle out altogether."
What wasn't known until now is that the bill itself will kill the market for private individual coverage by not letting any new policies be written after the public option becomes law.
The legislation is also likely to finish off health savings accounts, a goal that Democrats have had for years. They want to crush that alternative because nothing gives individuals more control over their medical care, and the government less, than HSAs.
With HSAs out of the way, a key obstacle to the left's expansion of the welfare state will be removed.
The public option won't be an option for many, but rather a mandate for buying government care. A free people should be outraged at this advance of soft tyranny.
Washington does not have the constitutional or moral authority to outlaw private markets in which parties voluntarily participate. It shouldn't be killing business opportunities, or limiting choices, or legislating major changes in Americans' lives.
It took just 16 pages of reading to find this naked attempt by the political powers to increase their reach. It's scary to think how many more breaches of liberty we'll come across in the final 1,002.
AS Jon Belushi said in Animal House
"Holy $h!t"
This is crazy. If this becomes law, it in essence will prevent you as an individual from changing plans, unless of course you go on the government plan. No more individual policies.......EVER
This may not be a big deal for someone in bad health, but for a health 40 year old who wants access to specialists without issues or waiting periods, this could soon become illegal......
The Sherpa Says: If you think that these changes will enable Personalized Medicine, think again.........Besides, the real costs in this system are drugs and hopsitals. Why bother with the providers?

Why SB482 is bust. I am amazed by smart people.

If any of you were on the receiving end of my email blast, bear with me. I have a few points to make this morning. A coupla weeks ago, June 24th to be precise.......23andSergey reposted a tweet which really got my attention......
The original tweet was "@23andMe BTW, you saved me $25 for a CF test - used my and spouse's 23 results instead. Thx!"
The user is a really super smart CEO of a company.
After Daniel MacArthur and I protested, 23andSergey pulled down the post........Normally not a big deal, but then came a tweet for me which really had me even further convinced of some issues with DTC
"@hh Really, how so? Our fertility doc says "either of you been tested as a carrier of CF?", yes, both know status via our @23andme."
Do they really know?
No. Truth be told, the delta508 mutation is not exactly the gold standard for carrier screening.....and what the hell? Carrier screening? Isn't that medicine?
Which brings me right down to it........State Bill 482 in essence says that these DTC genomics companies aren't really doing testing. They are only applying a mathematical algorithm to determine risk...........
Could you please tell me what algorithm is used to say you are or you are not a delta508 carrier in the CFTR gene?
Here's another question.
What algorithm are you using to tell people whether or not they have Ashkenazi Jewish Founder Mutations in BRCA genes?
The answer is, they are speaking out of both sides of their mouth. These companies are intellectually dishonest and are looking to pull a fast one here.......and their lack of care for customer or patient safety and health is amazing.
When they pulled that CF retweet, did they post a tweet which says "23andSergey services are not to be used for medicine, and carrier screening is part of medicine"
The short answer.
No.
The long answer, why turn away a customer base who is inferring that it can be used?
I was quoted at the bottom of a San Jose Mercury News article the other day I am an Internist BTW.......
But my point is this, in the world of scandal in politics and lack of transparency, shouldn't we be asking why a company who wants to do this research revolution but won't have an IRB, a company who wants to "Be regulated" buyt by their own rules, a company who has deep ties to a company whose bailiwick is data mining and archiving, a company who performs medical type tests and infers that they can be used as such (despite the fine print)......shouldn't they be held to some sort of standard here?
Are we in the field of genetics so desperate for attention that we let these companies slide in their own laws and their own rules? Do all ships really rise with the tide? We need to ask ourselves here, is this sort of quick shiftiness and legal manipulation ok for the field of genetics?
What sort of trust does it inspire to know that the laws regulating companies were written by the companies. Less than 10% of all congressmen and senators were ever doctors (for my curious detractors).
Why does the medical field come under fire? Lack of trust. Do we really want another chink in our armour?
Does the entire field of genetics and its amazing discoveries want in its midst a company who is willing to manipulate data, lawmakers and ethics to survive?
What does that say about the field? How desperate are we?
What does accepting them say about us?????

The power of Twitter and why blogging matters.

I am certain there must be a million stories like this out there. Devoted Twitterer attends conference that others cannot, recaps the talks via twitter as physician/new papa/blogger/entrepreneur virtually attends the conference via twitter and can give color commentary......
Or this one: Conference presenters hamstring regular news, while blogger gets strategic advantage by not registering as a journalist. Thus scooping the press...... Well, I have now seen and appreciated both in real time.
This weekend while I was recovering and taking care of our newborn I was able to attend a conference the AAAS hosted a conference entitled "Personalized Medicine, Planning for the Future" it was a scientific freedom, responsibility and the law program......... The microblogger was Dan Vorhaus Esquire and the venue was Twitter.....I know I would have loved to watch the streaming webcast, but alas I had dirty diaper and feeding duty, so I could not get to my laptop.......which led me to the next best thing......my iPhone.
What an amazing invention that IS actually worthy of Time's invention of the Year.......
The next story is a slap down of Daniel MacArthur (Pound for pound the best genomic blogger out there) Welcome back from 2 weeks away Daniel, take your beating! Credit Science Insider

Cold Spring Harbor Wants Scientist Bloggers to Follow Media Rules
At a recent meeting at the Cold Spring Harbor Laboratory (CSHL) in New York state, Daniel MacArthur from the Wellcome Trust Sanger Institute in Cambridge, United Kingdom, brought into focus how fuzzy the line between journalist and scientist is becoming. In addition to reporting on genetic variation in a gene that is active in fast muscle fibers at The Biology of Genomes meeting, MacArthur wrote several on the spot blog posts covering advances discussed by the participants. Francis Collins also mentioned results on his new Web site.
A specialized Web-based news service, Genomeweb, complained. Apparently there is some rule regarding when journalists can release information. Usually they are allowed to do so AFTER the meeting.......but Daniel did it before the journalists could, thus scooping them.......As a blogger who has been sued in the past due to blogging, let me tell you.....this could be scary business..... More importantly, it raises the question about Twitter.....Is twitter a microblog? Or is it a super fast SMS txt?
You see where I am headed with this.
In order for personalized medicine to progress, we all need to be in constant contact to let the flow of new ideas move........Could we actually be legally held to restrict its flow? Personally I think blogging and twittering is not exactly journalism, but it could be......even FoxNews has a twitter feed.
So who is and who isn't a journalist.....this could get almost as tricky as internet startup companies pretending to play doctor by running tests on your DNA and reporting results as if they were actually predictive of something.........
The Sherpa Says: Have to run, patients all morning. But as you drink your coffee and look at your DTC test results and analyze your CYP1A2....think about how much more that ability to microblog at a conference will affect your life than some 1 million SNPs will.........

The argument maybe defused. Quacksalvers?
- This bill would require an entity that provides post-CLIA bioinformatics services, as defined, to contract with a licensed clinical laboratory to process biological specimen collection kits, except as specified.
- The bill would require an entity that provides post-CLIA bioinformatics services to employ a specified expert for approval of the algorithms used in the interpretation of the biological data of a customer.
- The bill would further impose on an entity that provides post-CLIA bioinformatics services specified privacy, recordkeeping, disclosure, and audit requirements, and would impose specified duties on the State Department of Public Health in that regard.
- The bill would also subject those entities to specified provisions of existing law prohibiting unearned rebates, refunds, and discounts, a violation of which constitutes a crime.
- Because the bill would expand the scope of a crime, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
- This bill would provide that no reimbursement is required by this act
for a specified reason.
We will see if this bill passes. But if it does, it may mean the end of Auctioning Off Genome Scans......
Which puts this technology right in line with the rest of healthcare, where it is ILLEGAL/Ethical Violation to discount, rebate, guarantee or refund.
The Sherpa Says: In my mind, this argument seems to be: "You are healthcare or you are Novelty. You cannot chose both" If this law passes it would be in line with the government of California as well as New York......

Navi's New Job

In case you missed my recent posts about Navigenics and 23andME, let me recap.
1. They lost their CEO. Who was in essence an executive in residence for one of the venture firms funding Navi. I.E. Kleiner was running Navigenics to begin with.....
2. I predicted that by the summer these companies.....Navi and 23andME would show whether they were going clinical or way of the novelty test....Surprisingly 23andME continues to thumb its nose at academics, by launching research without having its own Institutional Review Board.
3. With 23andME now doing BRCA testing, while Sacramento SLEEPS, or is underfunded.....it is clear their intention is to go clinical and clinical research without taking any ethical or professional responsibility....
4. It is now clear Navigenics will go clinical, looking to recruit it's own lab staff........Where?
Sacramento.......
Who needs Ladders.com when you have Craig's List
Navigenics is a start-up company with headquarters located in Foster City, CA. with funding from three of the top Venture Capital Firms in Silicon Valley. We provide personalized health profiles for customers based on their genetic makeup. For more information see www.navigenics.com.
POSITION OVERVIEW
As a member of the science team, the Clinical Laboratory Scientist will help establish the clinical testing arm of the Navigenics Laboratory which is located in West Sacramento, CA. This position requires knowledge of clinical testing and the ability to be trained in molecular biology techniques, laboratory processes, specialized medical diagnostic laboratory tests, blood test procedures, and medical terminology in order to perform specialized medical laboratory diagnostic tests.
Wait a second........
Navigenics has a clinical lab? Really? I thought they were not doing the testing???? That was their half baked excuse right? Affy, does our testing, so we are exempt from CDPH.....
Well, maybe AFFY's lab is this lab? It IS in Sacramento...but then, why would Navigenics do the hiring????
Is this to appease New York? who has yet to let DTC enter the Empire State!
The Sherpa Says: If the genetics community allows this to happen, I will be surprised......Nawhhh, they are trying to write grants rather than stop the barbarian hoards.....Navi is going clinical, 100% certain of that now. Will they at least take the responsibility which the billionaire predisposed to Parkinson's won't?

Over 200 studies! What is BS? What is Real?
- In genetic studies, one potential cause of spurious associations is differences between cases and controls in ethnicity, a situation termed population stratification.
- Was measurement of the genetic variants unbiased and accurate?
- Methods for determining DNA sequence variation are not perfect and may have some measurement error.
- Do the genotype proportions observe Hardy-Weinberg equilibrium?
- Have the investigators adjusted their inferences for multiple comparisons?
I have several others to add to this list, but HUGENet covers most of them. What is HUGENet? It is the Human Genome Epidemiology Network and it is a "global collaboration of individuals & organizations committed to the assessment of the impact of human genome variation on population health & how genetic information can be used to improve health & prevent disease."
In essence this voluntary set of collaborators evaluates epidemiologically, NOT CLINICALLY, but epidemiologically whether a GWAS or other Genome study is valid. PLOS reviews thet workings of HUGENet in a nice article.
This is an important network to have.
In addition, EGAPP (Evaluation of Genomic Applications in Practice and Prevention) evaluates the validity and applicability of these results if they are attempted to be turned into clinical practice. This too is a consortium of physicians and scientists evaluating such tools. Genetics in Medicine has a nice article about the methods of EGAPP too.
It is important to note that these are not "in house" services. Why do I say that? Well it is a little cloudy if a company such as Navigenics or deCode is telling you that their tests are clinically valid......Why? Well, they are selling the tests. Doesn't that make you stop and think?
How does Navigenics review studies for clinical applicability? They have posted on it. In essence they require at least 250 cases and controls and have a limited requirement for independent replications.....unlike HUGENet.
Thus the quandary with "in house" statistical analysis for scientific validity OR clinical utility.
The Sherpa Says: If you want to know the skinny on any of these studies, you need look no further than EGAPP or HUGENet....rather than trying to make sense of it through your 23andME account or tursting deCode or Navigenics to provide "unbiased" evaluations.....
