Geography -- The Missing Vital Sign In Your Physician's Office

Posted: 03/11/10 10:42 AM ET

What do Hippocrates and Ethan Berke have in common, besides 2,400 years difference in their ages?Well, for starters they are both physicians -- Hippocrates of course lived in about 400 BC and Ethan Berke lives in the present. They both understand the direct connection between the "places" in your life and their respective impact on your personal health. They both concluded that your health depends on the air you breathe, the water you drink, and the environment in which you live. In fact, Berke believes that place (geographically) matters in your own personal health and so do many of his collogues in family medicine.

Berke suggests that place is another useful "vital sign" to any primary care physician -- someone who is concerned about the whole patient. This belief that our "places" are actually another "vital sign" is not so hard to grasp when he suggests in his correspondence piece in the Journal of the American Board of Family Medicine that "recommendations made in the clinical setting pertaining to healthy lifestyles -- more activity, better diets, avoidance of potential toxins or pollutants -- cannot occur in a vacuum. If our patients are in a home or a work environment that does not give them the opportunity to heed our recommendation, their chance of success will be diminished". Strong words but good advice!

Here is where I am on the same page with Hippocrates and Dr. Berke: where a person lives (and has lived) must be considered as part of the context in which clinical decision-making occurs. I would add that increasing the transparency and utility of the information upon which physicians make recommendations and patients are encouraged to comply, could change the way we all go about "partnering" with our personal physicians. So the next time you say "there is no place like home," think about its environmental context. The relationship we all have with our home, regardless of its amenities, is unique and potentially harmful to our health because of where that home is located geographically (and perhaps what products were used in its manufacture).

You don't have to look very far to find the evidence on this subject -- just keep reading! While we typically get introduced to our first "home" shortly after at birth without a choice, our personal and local environment either allows us to get a good start on life, or diminishes it from the start in many different ways. So our chances of success in achieving life-long health and wellness are very connected to the places we spend those early years. Of course, adults can control many aspects of their "local" environments. We can chose not to smoke or cook over open indoor flames and use indoor sanitation, etc. But children never get that choice.

A child has to trust someone else (like our parents and our governments) to protect our air, water, soil, and in some cases, our exposures to things that can harm us. This is a very big adult responsibility! You probably have your own story about geomedicine -- unusual health symptoms that can't be explained, cancers that run in certain families, neighborhoods, or communities, or the onset of chronic conditions that don't appear to have a genetic or lifestyle link. Suddenly people start to pay attention to what's around them searching for anything that might make discover a cause or offer relief or a cure.

Much like the mountain stream has a headwater, so does our personal health. Many will say that genetics is our health headwaters; but as the stream meanders across many different geographical landscapes, so does our health, accumulating unseen exposures and facing uncertain and not very apparent risks. The application of geomedicine, then, is about translating what we know about illness and disease and what we understand about the role that our various environments play in making us sick (or well), into practical information that allows each of us -- physician or consumer -- to make better choices about where we live and how we engage with our environments. There is much more to share about geomedicine. In my next blog I will discuss some of the interesting comments from readers about their own real life experiences with geomedicine.

If you're new to this discussion perhaps watching my TedMed 2009 talk and reading Alana Kornfield's blog on that event will help. Until then I always appreciate your second opinion.

As a healthcare IT analyst I have suggested in the past exactly what you are describing, ... that the location of home and work, or school, all constitute health factors. The GIS data for those locations should be a part of the electronic record for patients. In that way we can create reports that address the epidemiology of those location, ... environmental hazards (think Love Canal and Ground Zero), seasonal and regional variations in communicable diseases like H1N1, and so forth.

The incredible truth is that a prospect pizza shop owner gets more specific demographic GIS data than any hospitals of which I am aware. Organizations exist which could address this need right now, if we follow your sage advice.

The medical profession has been structured to create a template for disease using the DRG (Diagnosis Related Group) method. Medical professionals quantify patients' symptoms then classify them as probable causes associated with a set of diseases. Based on these set of symptoms, doctors will proceed with tests most likely to produce a "positive outcome (diagnosis)." Discrete illnesses associated with even the most generic geographies (our homes and workplaces) are rarely considered or discussed by most doctors. Some examples of such common bio-hazards are food additives, toxic cleaning chemicals including paints aerosolizing within homes and workplaces, butyric acid from decomposing ceiling panels, florescent lighting, formaldehyde used to treat furniture, clothing, carpet and phthalates used in PVC pipe, baby toys and a host of everyday objects. Prolonged exposure to any of these chemicals can have deleterious effects on our health. While the complexity of making any accurate diagnosis should incorporate ALL pertinent contributing factors -genetic, lifestyle, dietary etc- those geographically-related continued to be ignored. Given the dearth of astute doctors and patients who, through no fault of their own, fail to relate all aspects of their medical history, symptoms possibly related to a specific geography, will remain sidelined. There is a reason for the term "practicing" medicine: despite the knowledge amassed through research, medical science is still in its tween years. Our hope is eventually "practice makes perfect."

Most doc.s are more interested in whether or not your insurance card is valid than they are about any sort of holistic view of their patients situation condition. How would they fit holism into a five minute visit anyway?

I would place the blame for the five minute visit squarely on the insurance company and the AMA of the 1960's, not on the docs. After their expenses, primary care doctors don't make much more than their nurses. Backing up from that, I'd place the blame for the rise of the insurance companies squarely on the AMA, who promoted the term "socialized medicine" back in the '60's, thus ensuring that we wouldn't have universal healthcare and allowing the insurance companies to begin their climb. Only 30% of physicians today are a part of the AMA, yet the AMA continues to speak with a loud voice.

Thank You for your post and the information. I posted my comment as a patient and based it on my own experiences which are not conducive to glorifying the majority of doctors I have been seen by. There are some who have been very good and are of course they are very appreciated, but the banker/docs need to be gone yesterday! I have absolutely no problem with Doctors making a good wage, but like lawyers so many are so committed to these extremely high incomes that what ever expertise they may possess becomes, unobtainable to those who might be their patients, and therefore moot. Believing Doctors should make a good wage doesn't mean whatever they may want and doesn't mean that they should make more than schoolteachers who have the power to affect the future of peoples lives just as significantly.

And I do find the sixty-second medical service repugnant. You go and discuss very personal, sometimes life-threatening, often poorly understood topics in less time than McDonalds will cook you lunch. It is just disrespectful for whatever reason.

Call me skeptical, but I don't see how this would be useful in a clinical setting. This article does not provide a single example of how this information would be used in a clinical setting. Maybe, you are talking about some sort massive Artificial Intelligence that looks for patterns in a massive data set which is something that has not been invented, but is something that we should invest in. Perhaps? Otherwise, I think you would just pick up random blips in data that we be associated with addresses that would lead to probably more expenses through unnecessary tests and interventions. Please give an example of a disease that this would help screen for and demonstrate that this would somehow lower health care costs.

In the town I grew up in there was a train yard. Most of the trains were electric, and a few diesel. The yard was eventually declared a Superfund site due to heavy ground contamination with PCB's which were used in the transformers and motor cooling systems. The PCB's migrated in the soil, and contaminated nearby residents. Many are still being monitored for retained PCB's from the days when they were children, and are approaching 40 years or older. PCB's are know carcinogens.

If this data were made available in patient records, proximity of a residence or business to such potential hazardous materials could be discerned by physicians simply by comparing work and home data against a database of known risk sites.

By identifying the exposure, physicians can monitor for the effects, treat them earlier and reduce mortality and morbidity.

Mejor bad news-if not being able to choose your birth parents isn't the nadir of the pits, you have to add that we don't get to choose our own 1st home either. What kind of $hit is that? That proves that not all life is a gift. WTF good is that life? Be kind to your babby, wrap its head in flimsy, cheap, dry cleaners bags.
That sort of a 'life' is a booby prize for helpless, useless, boobies. That's the reason that non-theism is rapidly growing much more popular. Take this life(?) & shove it. Put up a sign that, "Life is a Gift." in front of your sanctuary (on all 4 sides) & your congregation will sink to 0, probably much lower, after you put up the sign(s).
No, bar keeper, no communion wine (whine), bring me an egg gnostic every time my glass is empty.
An egg gnostic is made with 190 proof, pure grain alcohol & Bacardi 151 proof, purple, rum. Portions are 19 parts PGA, 1 part 151. It's called the taste that wastes.
