Paging Dr Nano…

I’m kind of obsessed with the nanoscale world because it’s the scale at which basic living systems start. The macromolecules of cells — the building blocks of organisms — are really doing meaningful processes down at the nanoscale.

Nanotechnology — the technology of things designed and engineered down to the molecular and atomic level — is beginning to show signs for remarkable devices not far from going on the market. And one of the first, robust markets for nanotech is going to be medical nanotechnology, especially for cancer. I’ve been watching this for a few years years now.

I recently stumbled across a nanotechnology newsletter I hadn’t seen before: Nanowerk. It’s a European site focused on technology developments in European countries. Every country with healthy science and technology resources is steaming ahead with nanotech R&D in anticipation of huge future development. The newsletter circulates 10 to 20 briefs per day.

An article from May 4 really got my attention. It’s titled: “Informatics moves into nanomedicine,” and reports on research recently published in Pediatric Research. There are what I think are some interesting assertions about the near future of the field.

…some nanoparticles and nanodevices have already been approved or are about to be approved by the United States Food and Drug Administration, including, for example, superparamagnetic nanoparticles to detect metastases in some types of cancer or new devices that combine microfluids or nanosensors to detect tumours.

These applications of nanomaterials open up new prospects for personalized medicine, the authors add, indicating that classical clinical studies need to be redesigned to adapt to the advances taking place in genomics, proteomics and pharmacogenetics. “The introduction of nanoparticles that can target different molecules or groups of atoms with high precision can significantly advance the personalization of clinical procedures”, the article says.

But the statement that blew my mind is:

The possibility of biomolecular devices acting not only in vitro but also in vivo within diseased human organisms is also opening up new prospects, where biomolecular automata could even intervene to intelligently deliver drugs to the diseased regions of the human body just where they are needed.

In this respect, the authors note that research on a “Doctor in a Cell” is already in progress. This is a genetically modified cell that can operate in a human body. It contains a biological computer that can process and analyse external biological signals, emit a diagnosis and deliver the desired molecular therapeutic signal to treat the patient.

The doc-in-a-cell is “already in progress“?! Not exactly the Fantastic Voyage, but close enough to get me excited!

Walgreens blinks

Well, that didn’t take long!

On Tuesday I blogged about Walgreens announcement they were going to start selling a OTC genetics testing kit. I say were… Today they announced that they’re putting that idea on hold. As I predicted, the move started a firestorm and in just two days it was hot enough to get the big retailer to back off.

The FDA and a bunch of doctors and genetics experts piled on and put the brakes on the project.

“These kits have not been proven safe, effective or accurate and patients could be making medical decisions based on data from a test that hasn’t been validated by the FDA,” said agency spokeswoman Erica Jefferson, in an earlier statement Wednesday.

I’m having deja vu. That’s pretty much the same thing that happened when 23andMe and other gene testing companies went public back in ’07. Of course, some of the concerns expressed are not trivial.

The proliferation of consumer-marketed genetic tests has troubled many public health officials and doctors who worry that the products are built on flimsy data.

“The problem with all of these products is they’re based on incomplete, invalidated data and we don’t know what the impact on consumers will be,” said Dr. Muin Khoury, director of the National Office of Public Health Genomics at the Centers for Disease Control and Prevention.

The biology of how DNA variations actually lead to certain diseases is still poorly understood, although a number of public and private institutions have been racing to find answers.

That’s true. One of the themes of this blog is the unexpected complexity of genetic expression that has been uncovered during the past decade. Genetics scientists have been rocked back on there heels to the point of having to rethink some of the earlier assumptions in the field.

It seems that both the public and scientists have held some simplistic assumptions about how genes work. Scientists are making new discoveries nearly every day. So experts say with almost every breath these days: “Genes are not destiny!” Yep, the biology of what happens to us over time is much more complicated than that. So one of the most intriguing questions is: Why aren’t our genes destiny? If our state of being is an interleaving of genetic (internal) influences and environment (external) factors, how do they come together in the organism? That’s a deep issue that will take much more time to plumb. It’s one of those areas where scientists say: “It’s not fully understood.” (That’s science-speak for, “Duh!”)

My thought is that this is an opportunity to bring the public up to date and let them know the puzzle has 1,000 pieces, not 500 as first thought. We have been getting a trickle information about genetics for a couple of decades through media, but that volume is about to increase to a torrent. So where is the effort to help the public have a solid source of up-to-the-minute information? The federal government‘s agencies all have web sites with bits and pieces of the necessary information, but all-in-all the information on genetics is fragmented in a thousand places of variable currency and veracity.

So here’s my wild appeal: As a mainstay of our so-called health care reform effort, let’s extend the charge to our health and scientific agencies (NIH, CDC, NSF, DOE, NLM, etc.) to include making available to the public coordinated, up-to-date, evidence-based information on human biology, health maintenance, medical and scientific frontiers, and a realistic perspective about the circuitous route by which scientific progress is made . Make this available through state-of-the-art communication technology, i.e., the internet and its future derivations. Every citizen, doctor, blogger, teacher, or mom should be able to access reliable information on anything they hear about health in a few swipes of their smartphone. This is a big job and will take money. Surely in the billions budgeted for health care reform in coming decades this would be worthwhile. And this could be an international effort both in information gathering and in paying for it. Health research is global and the findings apply to all of us. The US isn’t going to go to Mars by itself, so why don’t we throw in with all the nations facing the same health issues?

Learning is a process. Walgreens accommodation to the regulators may eventually turn out to be part of something positive.

do patients need doctor navigators to use the internet?

In the March 25 New England Journal of Medicine Drs. Pamela Hartzband and Jerome Groopman of published an opinion piece titled “Untangling the Web — Patients, Doctors, and the Internet” in which they expressed a lot of concerns about how the internet is putting patients in touch with a lot of questionable information about disease and about how it is changing the doctor-patient relationship in an adverse way.

Since, overall, my views are about 180 degrees in the opposite direction, I’d like to quote some of their remarks and comment on them. (I recommend reading the full article so the context isn’t neglected.)

Information traditionally flowed from doctor to patient; the physician described the genesis and course of a disease and the options available for treating it. Often, pamphlets were provided to reinforce the doctor’s explanation and advice. The patient might then receive additional input from family and friends, usually in the form of anecdotes about people who faced similar clinical situations.

I can only say from my experience that the first sentence about information flowing from doctor to patient is pretty ideal. When I started working at the community level for a large national cancer organization in the ’70s there were doctors who not only didn’t explain the disease well but there were some who chose, on the basis of their judgement about the emotional frailty of the patient, not to tell some patients they had cancer. They’d tell a spouse or adult child perhaps. Fortunately, things have improved and, hopefully, the “don’t tell” practice has been replaced by informed consent. Still, I think for many situations the amount of information going to patients is limited by the short time allocated to face-to-face interaction with doctors. I am a Kaiser Permanente client. They have implemented email to doctors, online lab results, and an online information resource. The docs don’t give full explanations unless you press them on it.

Other patients whose diseases have no ready cure are drawn to chat rooms and Web sites that may make unsubstantiated claims — assertions that macrobiotic diets cure aggressive lymphoma, that AIDS can be treated with hyperbaric oxygen, that milk thistle remedies chronic hepatitis, and myriad other fallacious claims. Falsehoods are easily and rapidly propagated on the Internet: once you land on a site that asserts a false rumor as truth, hyperlinks direct you to further sites that reinforce the falsehood. Material is perceived as factual merely because it is on a computer screen. We sometimes find ourselves in the uncomfortable position of trying to dissuade desperate and vulnerable patients from believing false testimonials. Doctors may be perceived as closed-minded, dismissive, or ignorant of “novel therapies” when they challenge such Internet rumors.

Firstly, there is absolutely nothing new about charlatans and doctors who have been peddling snake oil and gimmick cures for generations. Again, when I went to work in cancer control my organization had a major effort to combat “quackery.” Many, many cancer patients were getting all kinds of bad advice and misinformation from naturalistic health magazines and other sources. (For a thorough tour of the quackery hall of infamy, see Dr. Steven Barnett’s site Quackwatch.) People by the thousands were going to clinics in Mexico for cancer treatments no responsible doctor would perform. This was rampant decades before the internet. There was an epic, nationwide legislative battle over Laetrile, the marketing name for amygdalin from apricot pits. Despite the best efforts of medical and public health organizations, especially in California, Laetrile production was legalized in 27 states . The arguments about “freedom of choice” from the ’70s seem to have echoed down the decades and have turned up again in the rhetoric against health reform, especially in the condemnation of  comparative effectiveness determination.

Secondly, even highly authoritative institutions have to change their tune once in a while. When I joined cancer public health in the ’70s the medical community almost universally rejected the idea that food and nutrition had anything to do with the prevention of cancer. People who talked about a relation between nutrition and cancer were sneered at and called the “fruits and nuts” crowd. Thirty-five years later as I approached retirement I had to chuckle inwardly many times about the current enthusiasm for the view that diet and nutrition are key to the prevention of much cancer. These days ya gotta eat your greens and grains!

Thirdly, doctors themselves are not always reliable sources of informaiton. That’s why we have second and sometimes third opinions. Drs. Hartzband and Groopman cite anecdotes about people who believe unsubstantiated information from the internet and suffer anxiety or waste doctors’ time. But I think most of us who have been around a few decades have our own fist full of stories from our own experiences or those of friends and acquaintances where doctors have failed to diagnose something or misdiagnosed situations, where lab tests have been wrong or complex treatments have been bolixed up in a hospital. I think the public knows all too well from well-publicized reports about medical errors by the Insyitutes of Medicine that the medical system itself is far from fault free. With regard to health it’s a risky world, even in the bosom of the medical establishment.

The article concludes:

As physicians, we are struggling to figure out how best to use this technology in the interests of our patients and ourselves. Although the Internet is reshaping the content of the conversation between doctor and patient, we believe the core relationship should not change. A relative recently asked us, “What can you possibly learn from your doctor that is not available on the Internet?” We suspect we’ll hear such radical sentiments increasingly in the future. Knowledge is said to be power, and some of the past imbalance of power between patient and doctor may be equalized. But information and knowledge do not equal wisdom, and it is too easy for nonexperts to take at face value statements made confidently by voices of authority. Physicians are in the best position to weigh information and advise patients, drawing on their understanding of available evidence as well as their training and experience. If anything, the wealth of information on the Internet will make such expertise and experience more essential. The doctor, in our view, will never be optional.

Uh, count me among the radicals. Let me say that the doctors are not totally negative about the internet, but their overall conclusion is that every patient should vet all their information through their physician. It sounds like they’re saying — like other professionsals who’ve had their domain disrupted by the internet — we’d all be better off if the internet went away and we could return to the status quo ante.

I’m just here to assert that that’s just not going to happen. The genie has been out of the jug for years and it’s not going back in. The Pew Internet and American Life Project has been documenting for years now the growing reliance of the public on the internet in health matters. Doctors just don’t seem to get it that there are needs that they’re just not satisfying. The use of digital media for health information and support is only going to increase, and rapidly.

My position is not that doctors are somehow unnecessary. However, I do believe that ordinary citizens are capable of knowing much more and doing much more about their own personal health and digital systems are an evolving platform for that. And after the so-called “health reform” slugfest we’ve been through I’m even more convinced that we all need to be more autonomous. We can’t continue to depend on a cabal of politicians, doctors, hospitals, insurance and pharmaceutical companies for our health. It’s just too important.

My suggestion to physicians is, instead of promoting a somewhat idealized notion of the doctor-patient relationship unsullied by the internet, why not work with citizens, professionals, and organizations to make the internet a better platform for the public and for doctors and patients to work together around their health issues? There are many support measures that can be undertaken. If docotors are worried about accurate information then why not build a comprehensive, evidence-based, easily accessible, user-friendly information resource? Medpedia, a project started by a consortium of medical and public health schools, is an interesting and constructive exercise along this line. Only thing is, the site is not public-friendly and so far the effort appears not to have attracted much involvement from anyone but professionals.

The concern about people not being able to critically evaluate health information is certainly legitimate. In fact, evaluating ALL internet information is an issue. But where is the support system for helping people learn how to do that? Why don’t doctors and organizations get busy spelling out some guidelines for evaluation and get them disseminated through many channels? That would be constructive and doable.

There already is a kind of parallel world of information and tools starting to envelope the health sector. (Tip: If you think the internet is something, check out the apps in the iPhone App Store supposedly intended for medical professionals but perfectly downloadable by anybody.) It’s like the way the blog-o-sphere enveloped journalism. After a lot of pining for their old, defunct newspapers, more far-thinking journalists have learned how to work with digital media and to reclaim their futures. Something similar is happening in medicine and, hopefully, perceptive medical professionals will learn how to work with it rather than try to will it away.

The family genes

I’ve written several posts about how there’s been a lot of criticism this year of the meager results of gene sequencing in finding therapies for diseases. The genetic keys to diseases have proven elusive to the point there has been discouragement in the field. But there’s perhaps a more positive note in today’s NY Times about two studies being published in journals on Friday. For the last decade the operating assumption of genetics and disease is that common diseases like cancer come from common mutations in genes. But a lot of tests on the connection between genetic mutations commonly seen and common diseases was not strong. Instead the conclusion has been emerging that diseases are really linked to rare mutations. So all those news headlines you’ve seen over the last 10 years of so that declare “gene for depression found” were wrong. It’s not that simple.

For three diseases — Charcot-Marie-Tooth disease, Miller syndrome and ciliary dyskinesia — it turns out that the genetic inheritance comes from more obscure genetic changes by way of Mendelian family inheritance. The studies sequenced the whole genomes of not only the children with expressions of the disease but the parents as well. So they got what you might call the whole-family genome. Identifying diseases that manifest differently depending on the mix of genes coming from mom and dad means that the genomes of the whole troop might be needed.

Fortunately the cost of doing a whole genome is dropping, fast. Complete Genomics of Mountain View, Calif., did the genomes in one of the studies at $25,000 each. That’s a whole lot better than the $3 billion for the first genome ten years ago. They’re promising the $10,000 genome to be followed by the $5,000 genome. Remember, the holy grail is $1,000.

I said in my previous post about the 21st century medical model that our personal health record will need to contain our whole genome. This suggests that linking the genomes of the rest of the family will make the assessments of lifetime disease risk a lot better.

Health paradigm for the 21st C, part 2

Okay, Part 1 of this post was precipitated by the Society of Participatory Medicine’s request for ideas about what members would like to see them do. I talked about my take on the whys and wherefores of participatory medicine. This post is a list of eight activities I’d like to see supported by the Society for Participatory Medicine:

1. Develop an actionable plan for the goal of enabling each individual to become his or her own primary care authority for 90%-95% of health incidents.

Primary care docs want to go specialist because it pays more, so why not elevate the individual to the primary care provider and boost the physician to the role of spcecialist involved as needed? A few months ago during the health care debate on The Health Care Blog I saw a remark (by a physician, as I recall) that about 80% of health events are handled by the individual: cuts and minor trauma, headaches, colds and flu, aches and pains, nutrition, supplements, upset GI, menstral issuses, and on and on. The “drugstore” often the supply center for first-line of public treatment. What if that percentage could be elevated to with the right tools and support to 90% or 95%?

2. Develop a plan for building well-developed, well-funded information support systems specifically to support lifelong personalized health learning and decision making.

The internet is little more than a platform for informaiton storage and cheap distribution with content kluged together from unrelated sources.  However, people have already adopted the internet as a primary source for health information (Pew Internet Surveys). But so far there is no well-funded health resource base specifically designed to achieve anything like the goal above. The internet is a hodgepodge of sites and information of variable quality. WebMD and other commercial sites provide general content as part of their marketing platfrorm. Wikipedia is one crowd-sourced way to compile informaiton, but its quality has been challenged and the whole enterprise criticized. Medepedia, with content from academics from reputable institutions, arose pretty much to be an authoritative alternative to the noise of internet health information, but it’s primarily a reference work and does not seem to have figured out the public involvement part. There are thousands of nonprofit and government sites with bits and pieces of information, but there is no sign of a national commitment to an architecture designed to empower the public with knowledge in a person-specific or engaging way. The only site I am aware of that seems withing striking distance of the comprehensiveness of necessary is the National Library of Medicine.  Their Mediline and PubMed resources might be a precursor to a more innovative way of supporting personal medicine.

The information from a well-designed and well-networked system should contain a mechanism that helps everyone understand what medical information is “evidence-based” and what the certainty level  of current evidence is. The substantiation of information should be on a dynamic, constantly-updated basis. The system should also help people learn that scientific process works toward greater certainty over time and grey areas with less than 100% proof are a necessary part of understanding medicine.

3. The integrated health knowledge network suggested in iten 2 should take a systems approach to human biology and medicine.

In the 20th century the human organism was disassembled for study by segmentation and reductionism. Specialized areas of medicine, nonprofit organizations, and governmental expert agencies took off in their own directions too. The result is a very fragmented picture of health that still dominates today. Knowledge supporting personal health engagement should put the puzzle of health together. The knowledge base of health and life education should follow guidelines that support clarification of how various sub-systems of the human organism play a part in the function or malfunction of the whole.

4. The approach to participatory medicine should be founded on the principle that learning about health is a lifelong matter.

Information should be communicated and made available on an as-needed or just-in-time basis throughout life but within a cohesive systems framework. As I pointed out in an earlier post, parents are beginning to accumulate and electronically record information about children at birth. With the cost of full genome sequencing plummeting it is likely that the process will eventually become routine at birth. It does not seem out of the question that health knowledge can start at birth with a full family genome and health history as a basis for baseline health assessment and risk estimation.

From the outset, children are curious about their bodies and many teachable moments are possible if appropriate information is provided in a personalized, situation-specific way. A whole range of age-appropriate information should utilize current and future technology to find innovative ways of interfacing health information with many learning opportunities throughout life. Games, avatars, social networks, and virtual environments could be employed to engage various groups. People cannnot and need not become experts in all aspects of medicine, but over time they can become experts about themselves and the health matters that are issues for them as indicated by genomic data, family history, race and cultural variables. Needless to say, a health support information system will need to have as its mission staying abreast of and innovating with emerging technology.

5. Facilitate the evolution of an open sytem of quantifying sensors and devices that measure many aspects of bodily function, health status, fintess, and consumption that can be seamlessly integrated with the knowledge network, EHRs and informed by personalized health models.

The problem with life is that we are born without a “dashboard” for our bodies and with no operating manual. When health problems arise the symptoms such as pain, swelling, and other sensations are often too late to prevent acute illness. And our bodies provide few perceptible clues about the percursors of chronic conditions.

Health 2.0 activity has shown that there are many entrepreneurs eager to supply devices and services related to a personal approach to health. But technology standards committees need to be established or coordinated so that devices and data supporting participation can avoid what has happened in the electronic medical record industry. Interoperability and integration are essential, and the particpatory movement will be inhibited if these characteristics are not incorporated from the outset. Open data standards, open applications, and open media standards are necessary to put together the systems of communication, data recording and transmision, security, and social networking that are sub-systems of the greater vision.

The price of admission for entrepreneurs for participatory medicine should be open standards all around. Consumers should be advised not to support products that cannot be integrated with other components of the greater system (motto: “Homie don’t play ‘dat”). An encouraging development in this regard is the Open Mobile Health Exchange . Nevertheless, ongoing advocacy in needed to keep standards open.

6. Drive a counter-culture movement that encourages the US population to reset its expectations of the market economy from tollerance of the current state of health irresponsibility to one of health-benefit.

The market system in the US is health-indifferent; it is not accountable for focusing on consumer products that are designed to exploit basic cravings regardless on long-term personal or societal health burdens. In fact health corruption and health correction are complementary streams of income. Billions of dollars are spent on the design and marketing of products that contiribute to illness only to be answered by products and services marketed to compensate and bring us back toward health. It’s an amazing wealth engine where the right and left hands wash each other.

The weird thing about health “responsibility” in US society is that, with regard to food and drink, only consumers, not producers of goods, are considered responsible. If we over-consume a product designed and marketed to maximize our consumption, the producer is not held accountable. That’s the way it used to be with tabacco, but we changed the preception of responsibility about tobacco between the 1970s and the end of the last century.

A similar cultural change is needed about food and drink. We have a start;  producers of suggary cereals and high fructose corn syrup drinks have been criticized for marketing them to children. Similar accountability — or at least  social scorn — is necessary for other consumables. Producers have gotten away with saying, “Hey, we don’t force you to drik all that corn syrup. It’s your fault, not ours.” Perhaps as the extreme cost in dollars to US society from obesity and its consequences generates even more pain we’ll be less willing to swallow the denial of culpabiity that the marketplace hides behind.

7. Advocate for the funding developemntof human biological system models that can be personalized so that a constant stream of information may be analyzed and used as a source of near-real-time feedback about our health status and behavior.

We need sophsticated human systems biology and computer health models based to the best scientific information. They should be designed so that health data from our genomes, family history, lifetime health history, and from daily activity can be combined to form a personalized profile or algorithm. Our own model — embodied perhaps as an avatar — could be constantly available to interpret data and give us feedback or status reports. Such personalized models could also set the appropriately personal context for health information and learning.

8. Work to support augmented reality development for an environment that will enable us to get information on-the-fly about what our options are for the things we eat and drink.

Institutional support is needed to creating an augmented reality environment of information for restaurants and markets via databases that support easy access to informaiton about what we’re consuming. Bar codes, wi-fi, Bluetooth,  RFID tags  and new future technology should allow smartphones to immediately obtain information about the nutritional content of meals in restaurants and packaged products in markets. I already use an app called “FoodScanner” that uses the iPhone camera to scan package barcodes, look them up on a remote database, and provide me with the nutrition information food products are required to have on the package. The information can be saved for future use, but the whole process is pretty klutzy. A system that automatically grabs infomation and checks it against a personal profile of stuff to avoid is not hard to imagine.

When I was  in school at ~13-years-old we had “hygiene” class in which we had to learn the parts of the body (“pipes and plumbing,” as it was known) and their functions. Then in high school we boys got movies and slide shows with “the coach” to graphically show how disgusting VD and pregnancy are. That was supposed to deter us from sex until marriage. It was also  all I got from public education about health. I suppose it was somehow supposed to enable me to maintain my health for life.

The steps I outlined above is, I hope, a more robust approach and consistent with technology and lifestyles of the near future. The iGeneration evidently no longer sees a reason to fill their heads with generalized infomation with less that obvious personal applicability. They already know they have the option of getting appropriate information at the time it’s needed. Perhaps they’re already aware that the infomation they’ll be exposed to during their lives will be changing constantly. Making this situation lend itself to a healthier population is going to require many elements working together.

The things I’ve suggested also are simply ideas for a long-term process. If there’s one thing I’ve learned from a career in public health it is that change tends to be a lengthy, nonlinear process requiring tolerance for uncertainty and unexpected developments. Change is a career, not a project.

Health paradigm shift needed for the 21st C, part 1

The Society for Participatory Medicine recently asked its members (I’m one; it’s open to the public) what they wanted from the society. The request prodded me to think about what might be undertaken to advance “participatory medicine” or “health 2.0” which are similar if not identical concepts. Others might be better at identifying distinctions.

The purpose of the Society for Participatory Medicine is: “To accelerate change in the culture of healthcare to a more participatory model, through leadership, advocacy, information and tools.” I think it’s fair to say “participation” means a more even role between doctors and patients in making decisions in medical situations. If you go back to my parent’s generation (mid-twentieth century) typically doctors held the information, authority, and decision making power in virtually all medical situations. People didn’t expect to need to know much because, if you got sick, you went to the doctor and he — typically, he — told you what was wrong, what he’d do about it, wrote the prescriptions, and sent you to the hospital if necessary. If you lived in that era you know that generation gratefully accepted the doctor’s direction and didn’t ask many questions. The TV show Marcus Welby, MD, dramatized the medicine of the time.

But, as I described in an earlier post, a portion of the population was not satisfied with the situation and began to question established practices. This was especially true of women not too happy with male-dominated gynecology. In the 1970s, as I recall, emphasis on “informed consent” began to grow. When I went to work in cancer public health in the early ’70s it was shocking to learn that some doctors did not tell some of their patients they had cancer because the physicians judged the patient couldn’t take the shock. The patient participation movement has really accelerated since the internet broke the dam on medical information. The public has gotten much freer access to information from sources other than their personal physicians, which, in may cases, wasn’t much.

That’s the past, the 20th century model. Where can we go from here? Organizations are pushing the envelope, but I’d like to entertain a few ideas for the 21st century that would shift health and medicine in a more radical way.

In earlier times much of health care was the domain of women: an extension of their maternal, nurturing role in the family. The late 19th and the 20th centuries saw the rise of “scientific” medicine. (For an excellent history get hold of sociologist Paul Starr’s, The Social Transformation of American Medicine: The rise of a sovereign profession and the making of a vast industry. The title alone says a lot.)  The complexity and volume of medical knowledge as well as the financial advantage of professional exclusivity eventually resulted in the consolidation of medicine into the system of medical education, licensing, legal authority for therapeutic practices, and self-policing that dominates today. And the swelling of a huge medical industry focused almost exclusively of physicians as the kingpins and market managers reinforced the doctor-centered system. The responsibility for learning and applying medical knowledge placed doctors in a paternalistic position while patients remained in a passive, unschooled position.

I would not challenge the notion that medicine has made great progress under the current system, nor that the trend to super-specialization of medical knowledge will continue. But I have to ask: Should relative passivity and health ignorance of the public and inability to make health judgments remain our aspiration going forward? Are we not capable of knowing much more, of participating more fully in  effective health behavior? That includes accepting the power and responsibility for our own wellbeing. In the past when information was more difficult to distribute relatively low health literacy might have been more understandable and acceptable, but surely we can do better in the future.

My position is that we have already more powerful knowledge tools than even a couple of decades ago and those tools are growing in capability as we speak. There are seeds of a potential to put individuals in a much improved position if we are willing to build systemic support and institutions that augment our abilities as much as the institutional infrastructure that supports the medical profession. It is possible if we have the will to put much greater innovation into it. I believe we can up our game as “patients” — the noun we have accepted — and relate to physicians and scientific/medical institutions in a more capable way.

This is not just some power grab. It seems to me taking charge of our health is not only possible, it is essential. The pathetic political struggle currently going on around “health reform” in the US shows how powerless we’ve allowed ourselves to become. While various interests use politicians as sock-puppets to stage a drama about the future of medicine, we citizens have become primarily ineffective, frustrated spectators. But I hope many folks have learned that we cannot continue to let our most precious possessions — our health and that of our family — remain in the hands of others. And we’ve learned our financial wellbeing is intimately tied to our health status. Serious disease has too often become a financial catastrophe aw well.

Well, I’ve spent a lot of words on the history and context behind what I think we ought to consider for a health promoting environment for the future. In the next post I’ll get down to grinding out the main points.

My self-tracking: the prequel

I mentioned a few weeks ago that I’m doing my thing with adopting a permanent exercise and diet regimen. (Who isn’t?) This program has evolved. Starting back in July 2009 I wanted to get on a self-improvement track. At the same time I was getting interested in what I think is a very significant trend: health 2.0, participatory medicine, e-medicine or whatever else people are calling it.

I started by setting up accounts in both Google Health and HealthVault. Neither is very suitable for what I wanted to do: keep track of my exercise and diet. Both are designed to enable people to set up computer accessible versions of the records their doctor or health provider has. Fortunately I’ve been in good health most of my life, and I don’t have any complicated records of disease episodes or conditions to put in there — even if I wanted to. I say “if I wanted to” because it became apparent that getting records into these PHR (personal health record) systems either requires hooking-up with a limited number of providers, using go-betweens, or just getting your paper records and manually transferring everything in. It didn’t seem worth it in my case.

However, I discovered that HealthVault offers the option of linking your medical records account up to the MSN Health & Fitness site. Health & Fitness is specifically for recording exercise and food consumption. The data and graphs are then accessible in HealthVault.

Good idea, I thought, so I started recording what I was doing in the fitness form. The Health & Fitness recording system calls for you to make a daily exercise and diet plan. Then you keep track of what you actually eat and do for exercise that day and enter it at day’s end. The program then compares your goals with what you really did. That was a problem for me because I never know what I’m going to eat, and I wasn’t embarking on such a controlled diet routine that I was going to control it by, say, preparing and packing my lunch to the office. So, for me, the food consumption planning was useless.

Also, the interface for diet planning and recording is poor. You can search for a food or drink and select from alphabetical drop-down menus. But no matter how many times you have the same thing there’s no way to get a shortcut to your commonly consumed items. Finally, the exercise planning and recording is set up around running or gym workouts. All I wanted to focus on was walking. Believe me, I’m way beyond the six-pack-abs stage.

After about three or four days I realized this wasn’t going to be something I wanted to do for weeks much less years. There was way too much “paperwork” involved through an interface that wasn’t very helpful. Indeed, I ran smack into what I think is a very common obstacle for getting people engaged with health routines: doing the manual labor of keeping track of your progress. There are notorious hurdles in the way of people keeping up sustained health routines, and this is a big one.

I realized pretty quickly that I needed a better way of gathering my data. Coincidentally my cell phone contract was up for renewal, and I latched on to what I hoped (or rationalized) would be a big step forward in convenience of recordkeeping: the iPhone. That was the next phase on my self-tracking saga, and I’ll go into using a smartphone in more detail in the next installment.
