Cost + Quality + Convenience = Value

My wife Beth and I had a rather spirited discussion about how we in the U.S. might be able to pay for the healthcare of our citizens. Being ever practical, and also owning the job of writing the checks that pay for the “health insurance” our company offers its associates (including us), Beth in effect is arguing for a national consensus on something we might describe as a baseline ‘value’ for healthcare. Others would label her concept a ‘floor’, but you get the idea.

What Beth intuitively understands is the tension between cost, quality, and convenience. You pick a baseline or a floor level of value and offer that to everyone. With training as a nurse and 15 years in healthcare administration, her idea of what constitutes the sum of cost, quality, and convenience naturally overweights the integers for cost and quality: outcomes should be essentially equal across the board at the baseline or floor level, and the costs of achieving that should be in some way equitably shouldered by something we could describe as “society”. Very practical. A strategy that lends itself to being observable and measurable.

What’s the rub? Well, only two of the three elements that make up value are covered. To obtain an agreed upon level of medical outcomes (mortality, morbidity, longevity, etc.) the cost is covered. Ah, but HOW you obtain those outcomes is still a variable. It is the FLOOR of value that is guaranteed. Our family is experienced a bit of this recently with Beth’s Mom. After a hospitalization she was living in a setting that ws providing excellent care at a reasonable cost, but it was a setting that did not provide any extras; it was old, not very pretty, and she could  have had a roommate. Her (and her daughters’) experience, what we might call “convenience” or  in our formula, was found to be lacking. The girls opted to move her to a nicer setting, one that will eventually involve a higher cost because of the enhancements to the experience, with no change in the already best possible outcome, or quality.

Therein lies the problem with any discussion about literally anything that we might discuss as a “right”. Is everyone entitled to anything other than the minimal amount of convenience/experience necessary to obtain the best outcome at an affordable cost?

If we examine food, we find something quite similar. No one among us would say that X Million people should go without food. Indeed, we don’t even really talk about true hunger in the U.S. anymore, we talk about “food insecurity”, the concern that we may become hungry. By the same token, though, no one asserts that everyone is entitled to the same quality of food. Not even a little bit. No, quite the contrary, all that is discussed is cost and convenience (access).

Now, of course, we in the CrossFit world (and to a degree in the medical world) argue that quality is an ineluctable part of nutrition, that one must extend the equation outside of food alone so that an explicit choice is made that prioritizes quality calories over other purchases (cell phone, cable, fancy car, etc.). While this is accurate and proper I believe that we can reasonably quarantine nutrition and keep it separate from other needs, at least for the purpose of our discussion. The universal concept of the interplay between cost, quality, and convenience holds true in nutrition/food on a global, grand policy making level:

You can pick any two, but only two, when you are declaring what is the minimally acceptable level.

My formulaic approach to the coverage of needs has a little wrinkle that should be mentioned: quality cannot be increased ad infinitum. In all examples we might evaluate there is a practical limit to the ability to improve quality or outcomes. The law of diminishing returns arrives in the form of the asymptote as quality rises. On the other hand, cost and convenience are unbound and can rise almost infinitely. It is the alcohol in a drink that confers the health benefit; the same outcome occurs no matter what you drink. One person’s jug wine from Costco is another person’s Chateau Lafite served in the Gulfstream V. You get the picture.

What will become of our conversations about issues such as healthcare? Will we arrive at a similar juncture to the one we have now in food, clothing, and shelter? Where quality (outcomes) and cost issues are addressed and everyone is left to make their own call on convenience/experience? Beth can’t see how it can be any other way. Me? I’m much less optimistic. That old “want vs. need” thing just keeps popping up. Confusion arises when a truly generous people confuse what people want with what they need. Need is measurable and therefore finite, whereas want is neither. We can, and should, all work to pick up the check for the needs of each. “Want”, on the other hand, is the proverbial “free lunch”, and we as a society will need to agree on that before we can even begin to discuss begin to talk about the mechanics of paying the bill.

TANSTAAFL. Heinlein was right.

 

Contentment, Complacency, and My Fitness Tracker

Where does being content end and being complacent begin? As an older athlete this question is just dogging me. The parallel question might be where is the line between being content and capitulating? These are both, of course, extensions of some of my recent thoughts on balancing the effects of relatively high intensity workouts with the countervailing effects on recovery, plus or minus injury.

There might be a more scientific answer to these, at least in so far as fitness is concerned, and it would come from of all places the fitness tracker world. As it turns out my latest tracker(s) have the ability to measure the beat-to-beat variation in heart rate (HRV). This measurement is a proxy for autonomic nervous system activity. A lower HRV means autonomic stress. If correlated with the previous day’s workout that would argue for either a lower intensity session or rest.

Is HRV ready for prime time? Well, world class endurance athletes and many professional athletes in other sports certainly think so. How about for us, the regular folks hoping to improve our fitness and along with that our health? Dunno. I’m impressed and frankly a little depressed to find that my HRV responded so classically to what was for me an intense WOD yesterday. For this to work one must have the discipline to dial it back if your HRV is low on a particular day (be content with your work), but also the discipline to ramp it up when your HRV is high (fight complacency and go to work).

In a busy life it is likely the second part that will prove the more difficult.

Optimizing Effort/Outcome=Minimal Effective Dose

Some time ago I wrote about the Minimum Effective Dose (MED), the concept in which we seek to optimize our results with the smallest amount of whatever it is that we are using to achieve that outcome. The quest to find the MED is one that crosses quite easily between my day job (medical) and my own quest for health (CrossFit). A quick mention of Eva T in Outside magazine and the program she uses with her clients sounds a lot like MED. The Everyday Math column in the WSJ provided an enhanced vocabulary for the journey.

Sometimes the MED really is a “something” you take. Here one thinks of medicine or food, for example. More often is the case that we are looking at a dose of time or effort. Or perhaps both. In this case we are seeking to optimize the effort as it relates to the outcome, to make the value of outcome divided by effort as large as possible. The rate limiting factor here is the Law of Diminishing Returns, of course: at some point additional effort produces such a small incremental increase in the outcome that it becomes not worth making. This applies to everything from WODs/week (or day) to decorating a birthday cake. At a certain point you just have to feel you’ve succeeded.

How, then, to know when you have reached this optimal level? Eugenia Cheng, the mathematician who wrote the WSJ piece, offers the concept of the “minimal acceptable standard”. Once she has reached this outcome the additional effects garnered from more effort have moved beyond the point where Diminishing Returns kicks in and she simply accepts the outcome. We would call these “minimal standards” goals, but the concept is essentially the same. We want an outcome; setting a target or a goal is step one in optimization.

Cheng then goes on to refine optimization with a discussion about boundaries. One is your goal, of course. In real life others also exist, things like a 24 hour day and a 7 day week and the need to make a living. The dose you choose, both qualitatively (what it is) and quantitatively (how much you get) is unavoidably affected by boundary conditions over which you have less control.In the end no outcome worth getting happens without effort. Health, friendship, or the unraveling of a gnarly math problem–you’re going to put effort in to get your results out.

Maximizing your outcome-to-effort ratio is just another way to say you are seeking your Minimum Effective Dose, in CrossFit and elsewhere.

Sunday musings: Opiate Overdoses and American Health

To the victors go the spoils. History is written by the victors. Truer words, eh?

I find myself turning off all manner of information outlets of late because they are all just so many repeats. The other side of that victor coin is that the vanquished simply repeat the lines of the victor when s/he was losing. Look no further than the kerfuffle about the Accountable Care Act. If you remove time stamps and the naming of characters what one hears or reads is essentially unchanged today from what was said or written some 7 years ago.

Try it.

My sense of ennui is so strong that it is fairly paralyzing. Is there no one out there who is willing or able to propose something that is truly new? Can we not even even come up with new or original complaints and criticisms? Must we be doomed to this endless cycle of sameness about seemingly everything?

It’s almost as if the vanquished do not so much fail to learn from history but that they work very hard to faithfully replay history in exquisite detail, dooming us all.

We are looking at a true health crisis in the U.S. In 2016 some 40,000 Americans died from opiate overdoses. This is more than the number of deaths by firearms by a factor of 4, and is similar to the number of deaths in automobile accidents. This morning I read a startling statistic: 7 million working age men are out of the employment market, and 1/2 of them take painkillers on a daily basis. Crazy, huh?

On CrossFit.com we agree that there is a general crisis of health in the American populace stemming from over-consumption of calories (most of which are high glycemic index carbs) and under-consumption of physical activity. Another equally startling story in this week’s news is the growing acceptance of excess body weight fat as some kind of new normal, a normal that should somehow be institutionalized.Total capitulation, that.  In this discussion one must add the over-consumption of alcohol, because countless studies have shown that this legal substance is responsible for all kinds of negative health effects, both direct and indirect. (As an aside, it does give one pause when one considers the possibility of legalizing another neuro-depressant, marijuana). As if this isn’t enough, we now must add to this toxic recipe the ingestion by any route of opiates.

The U.S. is regularly taken to task for its failure to sit at the top of the world’s life expectancy leader board despite spending the largest amount per capita on healthcare in the world. This criticism becomes more and more unreasonable as we dive further into what it is that actually drives statistics such as life expectancy. Deaths from overdoses are illustrative of the folly of conflating health and healthcare: there is nothing in the healthcare system of treatment that drives this statistic, and the death of these primarily young people has a disproportionate effect on the life expectancy statistic in which it is years lived that we are counting (and losing).

What, then, is to be done, especially in the setting here of health-conscious individuals? It behooves each of us to take a bit of personal responsibility in the discussion and pledge that we will utilize accurate nomenclature, and in turn demand that everyone else in the conversation do likewise. Health and healthcare are not synonyms. Likewise, healthcare and health insurance (itself somewhat of a misnomer) are not the same; one does not lose healthcare when one does not have health insurance, and for certain the ownership of a health insurance policy does not guarantee one access to healthcare. Indeed, because the outcome was inconvenient to the majority of entrenched healthcare interests, the landmark study of Oregon Medicaid recipients that showed no improvement in health outcomes in those with Medicaid compared with those without has been mostly ignored and purposely forgotten. We need to engage in this conversation, but do so with strict fidelity to meaningful terms.

From there we should lead in whatever way we can. This effort is not at all about the treatment of disease, at least not as far as we here are concerned, but rather one of Public Health. There are quite specific areas to be addressed if we wish to effect change. Each area must be subjected to a root cause analysis. Over-consumption of low-quality carbs is near and dear to CrossFit, Inc., and the battle against “Big Soda’s” influence has been engaged. Other influences such as agricultural subsidies should have a similar bright light shined in their direction. How is it that the dramatic reduction of drinking and driving has failed to render deaths from drunken driving a statistical anomaly? Perhaps someone can convince one of those know-better do-gooder billionaires globe-trotting in search of a trendy problem to throw money at to look a bit closer to home when they apply their famous intellect to new thinking about old problems.

As to the tragedy that is opiate overdose deaths, can we please have someone with no skin in the game be given no-risk access to any and all applicable data and just turn them loose? Some guy did a deep dive into the issue of scrubbing the internet of all vestiges of child pornography using a combination of massive computing power and an outsider’s view. Give someone like that the ability to examine the entire opiate ecosystem to uncover some of the hows and whys so that we can make some decisions of the whats of our response with more than just our typical SOP of some self-designated, conflict-of-interest-infected expert who declares that his/her solution should work because of what they are sure must be going on. This seems to be a new thing, after all, and rather young, too. Prior opiate societal infestations surely share some aspects with our present crisis, but I don’t recall the opium dens in the days of the Crusades so routinely offing their customers.

Anything that can be measured can be analyzed. Anything that can be analyzed can be altered utilizing the results of that analysis. What is needed is the double-edged sword of courage to uncover an unpleasant truth, and strength to set aside all manner of short-term personal gain in favor of a long-term solution for societal benefit.

We ought not let 40,000 lives representing hundreds of thousands of years not lived to be lost in vain.

Emotional Well-Being: Mental Health Deserves Equal Footing

Some time ago I wrote about creating a way to measure health. Real health. Health that encompasses every aspect of what it means to be alive and well. As a CrossFitter I definitely included Coach Glassman’s Disease -> Health -> Wellness continuum, and I also acknowledged the critical importance of his concept of “Fitness over Time”. As a classically trained physician/scientist there is clearly a place for more traditional metrics like blood pressure, serum lipids and the like, although they may, indeed, be an variable that is ultimately tied to fitness.

Where my thoughts on defining and measuring health seem to depart from most current trends is in the recognition that mental health–emotional wellbeing—is as much a part of being healthy as any other thing we might examine.

Think about it for just a moment. Most of what we would classify as mental illness has as many outward signs that we can see as diabetes and hypertension. Which is to say, none. Yet we—all of us, not just CrossFitters—see nothing but the good in treating diseases like diabetes openly and aggressively. There is no stigma attached to seeking care for your hypertension or your elevated LDL. To the contrary, if someone who loves you discovers you quit measuring your glucose before you bolus your insulin, they are for sure gonna get in your grill.

For whatever reason, mental illnesses, including addiction, are looked at quite differently. No one is asking the person with chronic depression whether she is taking her life-saving medication, for example. We might notice an insulin pump on a friend or family member, but then it’s quickly forgotten. Everyone seems to be very uncomfortable around the young man who has very obvious hand tremors from the life-saving medication he takes for his Bipolar disease. We all seem to be so much more understanding when we have to wait for a response from someone suffering from Parkinson’s Disease than from the young women who has the same symptoms as a side-effect from the medicine that quiets the dangerous thoughts in her head from Schizophrenia.

It’s not even necessary to look only at these kinds of severe mental illnesses when we are examining the importance of mental or emotional wellbeing as an integral part of being healthy. What good does it do to have a 5:00 mile, a 500 lb. deadlift, and a 1:59 “Fran” if it was self-loathing that drove you in the gym to get there? You may be quite accomplished, the envy of your peers, at the peak of whatever life mountain you wished to climb, and yet you cannot feel joy. How is it possible to be healthy without joy? I look at Usain Bolt and what I see is quite possibly the healthiest man alive. My friend Tim, the writer, tells me that Justin Gatlin has nearly everything that Bolt has—youth, fitness, wealth—but the combination of failure to knock off Bolt, and the public disapproval reigned on him as boos from the Rio stands has left him emotionally broken. It’s subtle, but if you look at his face in the blocks of the 100M Final it’s there.

Our complex and conflicted attitudes and feelings about mental illness are especially evident when the topic of suicide comes up. Just typing the word makes me uncomfortable. Even how we describe suicide is fraught with hidden meaning that reflects our discomfort: someone has “committed suicide”. Right? Someone committed an act that we simply cannot fathom, one that leaves the survivors completely without any understanding whatsoever. How could someone DO that? It’s as if every suicide is the same as the suicide of the crooked prison warden in The Shawshank Redemption when he looks out the window and sees his fate arrive in the front seat of a State Trooper’s car.

In reality most of the time it’s simply not like that at all. Nothing about it is simple at all.

The outer walls at the periphery of my world have been breeched by suicide twice in the last couple of months. One of them actually does feel a bit like that prison warden. Frankly, I am too conflicted, too aware of the external circumstances and not enough aware of the internal life of the deceased to offer much right now. The other one, however, just stopped me in my tracks when I heard. The loss was profound.It has also introduced to me a new vocabulary that I truly believe provides a starting line from which we can change how we think about not only suicide, but all of mental illness. A friendly acquaintance lost his wife when she was killed by suicide.

We don’t need to know all of the details of the story. Suffice it to say that in the face of a child’s illness she suffered quietly. Too quietly to be noticed. Perhaps she didn’t realize how badly she was suffering, or maybe she was like so many of us and couldn’t bring herself to see her illness for the life-threatening entity that it was. No one will ever know. What is clear, though, is that this was not anything about commitment. Kidney failure may be cause of death in a diabetic, but it is diabetes that kills him. There is no difference here. The cause of death was suicide. Her disease, her depression is what killed this young woman.

Each of us has a very few moments in our lifetimes that forever change us. On the second Tuesday of July in 2006, unbeknownst to me, one of those moments was transpiring in a lonely, dark corner. Joyfully, the moment was a beginning, not an ending. Regardless, once learning of the moment I was changed forever. Now I knew. You cannot see any marks from mental illness, no swollen appendage or insulin pump. But it is there all the same, and it must be acknowledged and accorded the same degree of care as any other disease that may take our loved ones from us. Mental illnesses are real, and they can be deadly. There ought not be any conflict or discomfort in treating them.

We may stop losing so many of our loved ones when start to see emotional wellbeing as part of being healthy.

 

Population Health v10.0

There is a certain arrogance in the academy, that vaunted group of professors who opine righteously from afar about pretty much anything they study. Add to that the well-known arrogance of youth with its inherent disregard for any and all history which transpired before the youthful reached the age of cognition and you have either a toxic combination of ignorance and impetuosity, or simply a laughably vacuous collection of paper thin pontification. Such is the case with a series of statements quoted yesterday morning from a lecture given by a young academic physician on the state of population or public health in America. He posits that there is a new movement toward moving healthcare from inpatient to outpatient. There is an equally new and heretofore unseen effort to make people healthy rather than treat them when they are not. This young doctor is calling his observations Population Health v1.0.

I’m calling it Bullshit.

The lecture in question was being live-Tweeted, but that is probably the only thing about the subject matter that can reasonably be v1.anything. Instantly available dissemination of medical information to a general audience is a truly new phenomenon. With it comes the danger of the wider audience simply accepting the information since it comes from an “expert”. However, along with the relatively naive broader audience we thankfully have a small subset that is either a) informed enough on the topic to offer a “con” opinion, or b) simply old enough to remember that there is a deep and meaningful history that predates what the young expert is proposing as new. Count me as able to check c) both of the above.

Population Health is simply a better term for what historically has been known as Public Health. While Public Health typically connotes some sort of governmental involvement, Population Health is a more inclusive, more powerful concept because it includes not only government programs but also private initiatives of all kinds. Public Health typically equates to top-down implementation of global governmental policy, whereas Population Health covers everything from large for-profit publicly traded companies to the tiniest solo-practice pediatrician. In fairness to the speaker (and in a kind of peace offering for what is to come) I do think his choice of a label is spot on. The rest of his thesis and its development? Not so much.

There is literally nothing new in the entire exposition. How can you call anything v1.0, the first iteration of something that is truly new, if everything that is used as an example is simply today’s version of yesterday’s news. Let’s start with his primary assertion, that there is a new move afoot in which healthcare is only now being provided in the outpatient, rather than the inpatient, setting. This can’t be a doctor who is taking care of any patients in the real world. It is long been the exception rather than the rule that a majority of surgeries take place in an outpatient setting. Heck, 99.9% of eye surgeries have occurred in this setting since the 1980′s. So, too, for invasive testing like colonoscopy, bronchoscopy and cardiac catheterizations of all kinds. It would be much more accurate to state that we are in the end game phase of this transition, v10.0 if you will. For crying out loud, this is such a mature part of the evolution of healthcare in America that any essence of patient-centered care that would require an admission to a hospital is dismissed outright, one more nail in the coffin of that now meaningless label.

How about the assertion that we are only now engaging in a concerted effort to improve the health of our population as opposed to simply treating various maladies? This one kills me. Really? All of a sudden the entire healthcare/government/industry axis is only now finally seeking to improve the general health of our people by preventing illness? Now, in 2016, we have population health v1.0?! That’s laughable. If our young scholar is anything like yours truly, the last stop he made before making his way to the lectern was the loo. HeLOOOoh. Indoor plumbing anyone? You can make a sincere argument that v1.0 of population health efforts occurred a hundred hears ago with the introduction of the kitchen sink and the toilet.

If we confine our discussion to matters more purely medical any reasonable view must acknowledge the tremendous life-saving effect of mass vaccinations for childhood illnesses. Smallpox, polio, and measles each killed hundreds of thousands every year before the advent of widespread vaccination programs. Even efforts which we would now condemn like the sequestration of TB patients in sanitariums must be considered a type of population health program. Despite our modern day fetish with privacy issues, the near elimination of syphilis  in the Western world through mandatory case reporting and contact notification cannot be forgotten or ignored.

When we talk of Population Health in this day and age we are typically talking about mitigating the effects of modern society. Indeed, in cases such as nutrition, we are actually talking about undoing the adverse effects of prior Population Health efforts. The U.S. government either simply got it wrong, or was led awry by a cynical effort by food producers who surreptitiously funded self-serving research. No matter. We are now in possession of a sedentary, overweight population susceptible to once less common diseases that now run rampant. There is little argument that the healthcare community should engage in the effort to keep people healthy as well as treat them when they are not. The notion that this is something truly new is a fanciful notion bred of what must be purposeful historical ignorance.

So, Population Health v1.0? Hardly. A process that arguably began with the invention of the flush toilet cannot be labeled new, no matter how good this makes a speaker, a system sound, or a concept sound. Those who fail to study history may be doomed to repeat it, though in this case there really is no need to do so. Acknowledge the past, make a sincere effort to place your idea in its appropriate slot in that history, and then make a case for your proposal. Have a little humility. There’s nothing wrong with being v10.0. Especially if it works.

 

 

 

 

 

A Quick Thought on Measuring Health

Thoughts I’m thinking while following a vacuous, arrogant, self-congratulatory, and epically ignorant of history exposition on public health over on my Twitter feed…

It seems as if the entire world is in search for the magic metric that will allow us to measure, and then manipulate, health. Frankly, I’m stuck in my own search for a metric that combines Fitness (as defined by Greg Glassman), traditional western medical measurements (serum lipids, BP, waist/hip, etc.), and emotional well-being. Wouldn’t it be something if all you needed to do was accurately measure your pulse? What if your pulse, one of the easiest things to measure there is–all you need is a second hand and the ability to count–could predict everything about your health with the exception of bad karma stuff like depression or cancer? More than that, what if you then could be told what your pulse pattern needed to be and how to effect that?

In Scandinavia a long-term study was done on men looking at specific variations in pulse. Resting, peak, speed to peak, speed to recovery and the like were all recorded, and cardiac events/deaths were then analyzed against the data. The result of this research was a proprietary algorithm, the PAI (owned by a company called Mio Global) that posits a direct association between specific pulse patterns and longevity. Indeed, they boldly state that a PAI of 100 equals up to 10 additional years of life, presumably free of decrepitude (reflecting my CrossFit-affected view of life). Imagine for a moment how earth-shaking this would be. Having an actionable metric for health, especially one that is as easily accessible as your pulse, would allow us to critically evaluate a majority of health interventions available.

Nothing is that simple of course, but it is quite easy to envision a pyramid of health, not unlike our CrossFit pyramid of fitness, with a base that consists of your PAI. Layer on whatever you please, but the smart money is that something that looks an awful lot like CrossFit’s 100 words of fitness will be in there somewhere.

I’m off to take my pulse and then do a WOD.

 

Measuring Health Part 4: Fitness ‘F’

Health should be defined along the lines of individual human potential. An actionable definition would go something like “the ability to live at the limits of your fullest potential without any encumbrance now or in a foreseeable future”. Fitness as defined by Greg Glassman and CrossFit–work capacity across broad time and modal domains–should therefore be seen as “applied health”. As such, since fitness at any given time is an accurate measurement of one’s functional ability, our variable ‘F’ should have the heaviest weighting in our Health Index.

Let us begin our discussion of Fitness by reviewing and dispelling several myths and misconceptions about the interrelation between health and fitness. First, is it really necessary to review all of the date which now stares us in the face as far as the importance of exercise in health? By the same token, it should be clear to any sentient being that not only is what we eat important (although we must concede that this may differ across populations) but how much?  Simple carbohydrates, manufactured substances meant to cheaply replace real food, harmful (trans-) fats–it doesn’t matter what KIND of nutrition plan you follow, these are all BAD. As I write this I am recovering from surgery and I am not able to exercise. Does anyone believe that I will NOT gain useless weight if I maintain my pre-operative food intake? This part isn’t rocket science, folks. Coach Glassman says it as well as anyone: “Eat [protein] and vegetables, nuts and seeds, some fruit, little starch, and no sugar. Keep intake to levels that will support exercise but not body fat.”

Next up is the canard that fitness is simply being able to do something for a very long time. This view, promulgated and propagated by the likes of Outside Magazine and others, is not only insufficient but has been shown to be false as well. In the last couple of years there have been a number of very important studies showing a degradation of heart function in so-called “Ultra” athletes in any area. Decreased cardiac output and an increase in cardiac arrhythmias such as atrial fibrillation have been shown to be caused by excess endurance training. Endurance as the sole defining characteristic of fitness is as incomplete as would be strength. One need only look at the life expectancy of the strongest humans on record to see that strength in and of itself is not sufficient to produce health.

The question of what constitutes fitness is one that has been answered, at least insofar as health is concerned. It is not enough to be able to run or bike or swim long distances if you cannot also lift heavy things, including your own body. In the same vein one is not truly fit if one can deadlift or squat 3X his or her own bodyweight but cannot run a mile in under 15:00. One must have some measure of BOTH. As such the inescapable conclusion is that Greg Glassman is correct when he says that fitness equals work capacity across broad time and modal domains. You must be able to lift heavy things over a short distance when necessary, but also possess the ability to carry lighter things a longer way for a longer time as well. While I am not naive enough to expect that this will be accepted without spirited debate, when it comes to any measurements of health now available, all arguments to the contrary are not supportable. Glassman has won this battle.

As an aside, this should once and for all put to rest the myth of the “healthy obese”. What good is it to be happy, ‘W’ off the charts, with a stratospheric ‘M’ because all of your bloodwork is perfect, to go with your BP of 120/70, if your joints will cave under pressure decades sooner than they need to? You simply cannot escape the reality that health requires physical fitness.

If fitness can be described as “applied health”, it stands to reason that it will have the greatest contribution to our eventual Health Index. As such it is especially important that our chosen tests meet the criteria outlined in Part 1, that the measurement be as broadly accessible in all ways as possible. In the purest sense we would be able to measure an individual’s “work capacity”, the totality of his or her expression of fitness as measured by many tests covering different loads, distances traveled, and time. In CrossFit we talk of this as the “area under the curve” of a graph that records Power (lbs-ft. per second) on the X axis and Time (in minutes) on the Y. In a perfect world this would be part of every individuals ongoing pursuit of health, but alas, even in the CrossFit world where a very committed everyone records everything, this has proven to be problematic. In designing a series of tests to be applied to the broadest possible swath of humanity this ideal must yield to a more pragmatic approach.

What, then, should we measure, and how? Let us first propose a couple of general characteristics of the tasks in our test and then see what fits the bill. We should test an individual’s ability to move from one place to another under their own power–running is a fundamental human trait and should be part of our evaluation. Likewise, the ability to pick something up off the ground is a pretty basic, everyday movement and would qualify as our test of strength. Lastly, in the U.S. we have a storied heritage from the 1960′s, The Presidential Council Fitness Challenge (PCFC), in which candidates are tested on their ability to perform calisthenic exercises for both speed and endurance. It would be fitting to include something that evokes this historical element.

Once again I anticipate a vigorous debate about the particular elements we include. I’ll go first. We can reward both speed and endurance by starting with a timed run in which the result is distance traveled. The most common example of this comes from athletic programs and the military: a 12:00 timed run for distance. We live in the U.S.; the unit is yards. Pick up something heavy? Sure sounds like a deadlift to me. Any deadlift you wish, standard or sumo, will do. My bias is that a lifting belt is just fine, but except in very special circumstances (e.g. one-armed subject) I would say that straps to help you grip the bar are not a good idea, especially for the very inexperienced subject.

After giving considerable thought to the exercises and format in the original PCFC I think we should simplify the test while at the same time bringing it into the modern fitness world. In the PCFC one sought a maximum number of reps in 2:00 of pull-ups, 2:00 of sit-ups, and 2:00 of push-ups. What exactly are we testing with sit-ups that reflects true fitness? I would favor swapping out sit-ups for air squats. With a nod to CrossFit and Greg Glassman’s outsized contributions to this discussion, let’s use the format made famous by the CrossFit WOD “Cindy” with a small adjustment. To test our subject’s ability to perform bodyweight movements and move quickly, repeats of the triplet of 5 pull-ups, 10 push-ups, and 15 air squats in 6:00, counting as our result the total number of repitions achieved.

There you have it. A definition of “Health” and “Healthy”. The introduction of the three variables that go into the measurement of “Health”: traditional medical values ‘M’, emotional well-being ‘W’, and Fitness ‘F’. Next I will address how we will value each of these measures, and then ultimately how they will be combined to give us a meaningful, actionable health measurement ‘H’.

 

Measuring Health Part 3: Emotional Well-Being “W”

2016 is an Olympic year. We will hear stories, as we do in every Olympic cycle, of the extraordinary physical accomplishments of Olympians in sports which require otherworldly amounts of what we in the CrossFit world would consider “Fitness”. Strength, speed, and agility. Uncanny feats of coordination and accuracy, some performed over distances and times that are so far beyond the reach of the average human as to defy credulity. Many of these athletes, certainly the ones we will meet through the intercession of NBC, will match our expectations of the happiness that must certainly accompany such outsized achievements. Mary Lou Retton, anyone? Indeed, what we will see on our screens will fairly scream “Healthy”.

But there will be others, too. And for all of their physical fitness, expressed so dramatically for our viewing pleasure and patriotic zeal, the lack of emotional health will make it obvious to anyone that they are not healthy. Bruce Jenner, anyone?

Remember our proposed definition of “Healthy”: Able to perform in all ways at the farthest limits of one’s potential capabilities. Health is therefore the state in which no infirmity is, or can in the future, impede this ability to fulfill a potential. It takes but a moment to think of how mental illnesses such as depression, bi-polar disease, and schizophrenia can be hidden from view when examining only physical metrics. There are examples all around us. The woman who partners with a 1400 pound horse in the rigorous, physical tasks required to compete in the three-part test that is eventing, so poised and accomplished in the arena, who retreats to solitude outside the barn because she is incapable of overcoming her anxiety around people. The outdoorsman who in his manic phase performs feats of strength and endurance others can only marvel at, and then plunges into the depths of depression from which he cannot see the noon-day sun. Much more prosaic and much more common is the individual who continually increases his or her fitness by any and all measurements due to a deeply held sense of low self-worth, perhaps even self-loathing, pursuing an unreachable ideal and always falling short.

A truly universal measurement of health must include some element of emotional well-being. Let’s call it “W”. You could certainly call it the “Happiness Factor”, and some undoubtedly will. I imagine criticism directed toward this to take the form of “Happy Face” mockery. No matter. Well-Being is a better term for this part of our equation because it encompasses more than whether or not you are happy, whatever happy may mean to you, when you are measured. Are you content with your circumstances at the moment? Do you have the ability to persevere under duress?  What is the state of your relationships? A recent study of Harvard men carried out over decades found that both happiness and longevity were tied quite closely to the quantity and quality of your relationships with family and friends. Where are you in your pursuit of your goals, your dreams, and how do you feel about that? How much stress do you perceive in your life and how are you managing that? All of these make up what one might think of when we consider Well-Being.

How, then, should we go about measuring ‘W’? Remember, all of our tests should meet the dual imperatives of being accessible to pretty much everyone, and as inexpensive as possible. We could certainly use something like the classic anesthesia “smily face” pain scale, relabeling the figures, but this feels too simplistic and too momentary to be truly applicable. Our measurement should require a bit more thought than that. I have to admit here to countless hours of internet crawling trying to find a validated test of emotional well-being that has a track record in a heterogenous group that mirrors our population; most have been utilized in very specialized populations (e.g. soldiers) with a very specific research interest. Those that might apply must typically be purchased.

John Pinto is a well-regarded consultant in the world of my day job, ophthalmology. He has long had a list of clients that spans the gamut of pretty much every measurement you could think of in a group of doctors. Men and women. Young and old. Fantastically successful doctors and those that could only be described as spectacular (if unexpected) failures. As part of his quest to better understand his clients in order to better serve them, John used a questionnaire that measured emotional well-being. He found that external measurements of success such as volume of surgeries, income, and professional acclaim did not always coincide with his clients sense of success, their emotional valuation of their professional lives. These were certainly variables that mattered, but his happiest clients were not always his wealthiest, and his least happy not always those who had less. The assessment he used is the best one that I’ve been able to find, notwithstanding the fact that it is not free.

I am not wedded to the Psychcorp assessment and would happily review any alternatives. Especially if they are free! As is the case with ‘M’, our traditional health metrics like blood pressure and serum lipids, I expect a vigorous debate as to the relative weight of ‘W’ in our final Health Index. My bias is that ‘W’ is a current factor with a greater impact on health, and it should have a correspondingly greater weight in our formula. Let me start the “bidding” with double; however the final formula shakes out ‘W’ should have twice the value of ‘M’.

Mental health is an inextricable part of health. It must be included in any serious definition and measurement of health. Our variable is “Well-Being” or ‘W’.

 

Measuring Health Part 2:The Traditional Metric ‘M’

Any measurement of health must provide some sort of predictive value with regard to the likelihood that one will remain healthy. While the entire idea of screening tests is fraught with controversy–both false positives and false negatives bring with them real risks–there are still a number of health measurements in the realm of traditional medical care that have a proven value when trying to predict downstream adverse health events. The trick, of course, is to decide which ones matter, filter that group to come up with tests that are as close to universally available as possible, and then decide how much weight each particular test in the group of survivors should receive in the single cumulative metric that is then created. This measurement, call it “M”, will be one of the variables in our calculated health measurement.

Let’s start with the simplest of all medical inquiries, a medical history. More specifically, let’s include a brief family history in our calculation of M. While it is becoming increasingly easy to obtain a very accurate genetic profile that identifies very specific health risks, these genetic tests are both controversial and expensive. Until the very real societal issues of knowing your exact genome and the risks it includes have been worked out by both ethicists and elected government, we should take a simpler and more narrow approach and ask two very simple questions: Has anyone in your family died from heart disease? Has anyone in your family died from cancer? Equally simple follow-up questions (How young were they? What kind of cancer) would allow us to add risk (reduce M) or ignore the historical note since the disease is not hereditary.

From here we move to an equally spartan individual medical history. Again, just two questions in this part: Do you smoke? Do you drink alcohol? The negative effect of smoking on an individual’s health, both in the present and future tense, must be accounted for in any measurement of health. It weighs so heavily on what we know about future risks that we will see it as a negative integer in M. Too many studies to count exist pointing out the deleterious effect of excess alcohol consumption to count. One compelling study, The Eight Americas Study in PloS One, found alcoholism to be the single most powerful lifestyle variant after smoking when predicting the life expectancy of groups studied. A recently published study of Harvard men found that alcoholism was the greatest second greatest influence on the happiness of the men studied, just behind the presence of loving friendships. Unlike smoking, however, there is a volume component to alcohol consumption. Indeed, a modest intake actually INCREASES longevity, while no intake DECREASES longevity. So M will see a small bump from moderated alcohol intake, an equally small decrease for teetotalers, and a dramatic negative effect from heavy alcohol intake.

So far we’ve managed to obtain some variables underlying M through the use of simple inquiry, costing only the time it takes a subject to fill out a questionnaire. At least two other variables are as accessible and inexpensive: blood pressure (BP) and a measurement of body habits. Once upon a time you had to visit a doctor or hospital to get your blood pressure checked. Now? Heck, for $20 you can buy a reasonable accurate BP monitor and take your BP at home! Minute Clinics in pharmacies, health clinics in the workplace, and coin-operated machines in the local Mall now make it easy to get a BP without visiting a doctor. While there is ongoing controversy in the medical world about what constitutes Hypertension it is safe to say that health risks are higher with a systolic pressure >140 and a diastolic >90. Above or below these levels is our toggle for M, positive or more healthy for lower and the opposite for higher BP.

Using body habitus is controversial, mostly because the measurement that is routinely utilized is so inadequate. The Body Mass Index, or BMI, is wildly inaccurate when it is applied to the fit. 4-time winner of the CrossFit Games Rich Froning, arguably the fittest man on the planet, would be deemed obese at 5′ 10″ and roughly 195 pounds with a % body weight fat of around 4%. Ridiculous, huh? The temptation, of course, is to use % BW fat as the preferred method of measuring body composition risk, but measurements that are accurate enough to be useful tend to be very expensive and difficult to access. On the other hand, all you need to determine the waist/hip ratio is an 89 cent paper tape measure and a calculator. A waist/hip ratio of >1.0 is associated with an increased risk to health from myriad metabolic illnesses including diabetes and heart disease, especially in men. Greater health in M for measurements under 1.0, and progressively less as that number increases.

It is impossible to utilize all that modern medicine has to offer when it comes to measuring health without spending a little bit of money. Several simple blood tests can be obtained with or without the input of a physician. The presence or control of diabetes can be ascertained with a HbA1c and a fasting glucose level. In the presence of a normal HbA1c an elevated fasting glucose may indicate a problem with insulin sensitivity, so it is important to include both. While it is far from settled whether or not it is cholesterol itself which is responsible for heart disease there is simply too much evidence that serum lipids can help predict cardiac events to leave them out of any health measurement. Our basic health index should therefore include the basic measurement of total cholesterol, HDL, LDL, and triglycerides, and M should reflect the negative effect of elevated Total Cholesterol, LDL and triglycerides and the positive effect of a high HDL.

How should we put all of these together to come up with our traditional health variable, M? This one is fairly simple; there are a number of “risk factor” measurements online that are good models. I envision a rather simple form on which one would add up weighted values for the measurements above, arriving at a straight forward mathematical sum. The final formula is being developed with the assistance of cardiologists at my medical school alma mater, the University of Vermont.
