Is One DIet Program Better Than Another for Weight Loss?

As a doctor, the Population Health Blog was often asked by overnourished patients to help find a "best" diet.  Its advice to simply eat less and skip desert, however, was insufficient to overcome the commercial programs' allure of word-of-mouth, dubious advertising and fanciful on-line marketing . As a result, many desperate PHB patients fell into closed loops of pseudoscience, anecdotal testimonials and expertly crafted statements "not evaluated by the FDA."

As a population-health skeptic, the outcomes-focused PHB was never convinced that one commercial diet plan was "better" than any other.  Not only are excess calories very efficiently turned into corpulence by a very efficient human metabolism, it didn't make sense that that persons could eat their way to weight loss with more [insert one of the following: protein, fat, fiber, pre-packaged meals or vitamins].  Last but not least, if all these commercial weight loss outfits spent a tenth of their marketing budget on real science, the PHB may have had the evidence it needed to make a recommendation.

Well, a meta-analysis of "Named" (you'd recognize the brands) diet program outcomes has been published in JAMA and the results are decidedly unimpressive.  The good news is that all of the household-name programs result in modest weight loss compared to no diet.  The bad news is that the loss of two to six pounds for each program was no better or worse compared to the others.

The PHB's take?  It's up to the consumer to weigh their personal preferences for one type of diet plan vs. another.  In addition, out-of-pocket costs may also play a role in helping sustain the dieter's motivation in getting their money' worth. 

Beyond those two considerations, however, it's just a matter of eating less calories, not more of the latest nutritional fad.

Of Risk Stratification, Health System Variation and "Stupid" Decision-Making

A fly in the ointment
Years ago, a middle-aged Population Health Blog patient came in for a routine follow-up appointment.  Since his last visit, he had developed iron deficiency anemia. Since slow blood loss can be a sign of an early and curable cancer in the gastrointestinal tract, the PHB recommended a series of unpleasant tests. After a rather routine explanation of the time, expense and inconvenience of those tests, the patient surprised the PHB with a one-word answer: "No."

He went on to live for decades.

Which brings the PHB to this JAMA article on individually-tailored screening for another type of cancer. While even screening for prostate cancer is controversial, it's possible to stratify a man's risk of the condition with some questions, examination data and test results.  That risk can be portrayed in lay terms (there is a "42-in-100 chance" that cancer is present, but doing a biopsy has a "4-in-100 chance of causing an infection..."). 

The points of the well-written article is that 1) risk-stratification can be used to identify persons at high vs. low risk, 2) the decisions to screen, perform additional testing and embark on treatment can be, based on that risk, "tailored" to maximize a good outcome and 3) patients can use their level of risk to ultimately decide how they want testing and treatment to achieve the outcome they want.

Bravo, says the PHB.  While we're on the cusp of understanding whether a more sophisticated approach to screening ultimately leads to better outcomes than the standard all-or-none guideline (USPSTF "recommends against prostate-specific antigen (PSA)-based screening for prostate cancer"), there is enough face-validity to believe that patients will ultimately benefit.

But there is a fly in the ointment and a monkey in this wrench.

The fly? Variation will not go away. While health system bureaucrats everywhere would prefer that 0% of men undergo prostate screening, that 100% women over 50 get mammograms, and that 0% of us have a body mass index in excess of 25, individuals - after looking as the risk-benefit here, here and here, may choose otherwise.  We don't know what the "right" screening rates are.  In fact, we may not be asking the right questions.

The monkey?  Some "bad" decisions will occur. Once persons truly understand the benefits, risks and alternatives (including not dying prematurely of a preventable illness and side-effect risks that are less than driving in a car), they are allowed to make "stupid" decisions.  Physicians and bureaucrats may not like it when anemic patients, like the one described above, refuse no-brainer recommendations, but in a free country that's the price we pay. Our challenge is to make sure that our patients have all the information they need (which is apparently not the case here) to make a truly informed decision.

Is the United States the Only Country Into "Patient Engagement?" (plus a definition)

Patient engagement is there too!
The answer is no.  Check out this paper in Health Affairs that defines patient engagement as ordinary people who manage their own health by shifting the clinical paradigm from determining “what is the matter?” to discovering “what matters to me?” 

The authors point out that patient engagement is a phenomenon in Great Britain, the United Arab Emirates, India and the United States:

England's "Big White Wall" is an online community accessible via handhelds or computers where persons with psychological distress can find support in managing their care.  Participation is anonymous and is covered (£100 for 6 months) by some of the local National Health Service organizations or by employers directly. There are questionnaires, guided support programs, moderated discussion groups and individual 'live" therapy (£75 per session). Supporters point to data that suggests there are fewer physician visits that result in a net savings.

The United Arab Emirates' pattern of tribal consanguinity has led to a high incidence of inherited genetic disease. In response, the UAE recruited and paid student "ambassadors" to lecture about genetic screening among the country's university student population. That plus mandated screening plus coverage of the cost has led to an increased tribal acceptance of screening for thalassemia and sickle cell disease.

In India, a checklist was promoted and given to new mothers to help them spot danger signs in their babies within a week of birth. The checklist was loaded on the mom's cell phones, which was sent prompts about looking for problems, such as breathing difficulty or poor feeding. If there was an "yes" answer to any question on the list, the health system was alerted.

In the U.S., Boston's Deaconess Hospital identified a hundred patient and family "advisors" who sit on ten committees and give input into various quality improvement projects in the institution.  This has facilitated the ability of patients and families to view their test results on line, get prescription refills or trigger an inpatient concern.

Underwriting vs. Care Management

Rock on, care management
In the course of learning about care management, the Population Health Blog has benefitted from sitting at the feet of high-functioning finance experts, actuaries and underwriters. Reconciling health care revenue/expense, trend, monetized risk and pricing of insurance with the savings, quality and patient experience that comes from optimized care has been a fascinating - if sometimes frustrating - intellectual exercise.

However, this report on the rise of machines and the continuing displacement of knowledge workers reminded the PHB of the divide between the science and the art in this corner of health care. 

According to David Autor, it's only a matter of time until machines begin to displace the high-end brainiacs who oversee the health insurance industry's premium, reserves, claims payments and surpluses.  Human judgment will never go away, but logarithmic jumps in processing power combined with the big data that comes from industry consolidation means the "answer" on how much to charge for coverage of a person with diabetes will be less flexible and more preordained.

The PHB, however, is of good cheer. 

While underwriting risk will be all about the numbers, managing conditions within those numbers will remain a very individual enterprise. Human needs, preferences, tolerances and culture will continue to shape highly variable decision-making within the care system for years to come. The need for highly skilled knowledge workers who can help patients co-manage their care will grow, not diminish. 

Factory farms may be churning out ingredients on an massive scale, but someone has to plate the finished meal. 

The music industry may be selling Beyonce at $0.99 a pop, but nothing will replace seeing her live in concert.

Payers and buyers may commoditize cataract care, but someone has to make sure patients take their eye drops.

Underwriting on one side.  Care management on the other.  The PHB likes where it's at.

The Growing Parallels Between Health Care and Power Utilities

In some of its past musings, the Population Health Blog drew parallels between the airline industry and health care. While it knows nothing about aviation, who cares? It figures all those pundit MBAs and lawyers know nothing about medicine either: such is the standard of today's commentariat.

It knows nothing about power utilities either, but the gullible PHB sees parallels there too.  According to this Dummies chapter, utilities sell a heavily regulated commodity that requires a lot of debt-financed infrastructure. Since their customers have no where else to go, poor/low cost service can translate into it being considered a safe investment. Yet, do-it-yourself renewable energy is a growing threat. As companies go, they are not known for growth; rather they preserve capital and return profits to their investors in the form of dividends. And regulators are forcing these companies to reward customers for using less of what they're selling.

And what's the growing resemblance to health care? 

In their attack on variation, many services are being commoditized into a race to the bottom by payers and government.  Regulation is increasing. Poor/low cost service for "captive" patients can also mean greater profits.  The importance of access to capital, servicing debt and achieving savings are eclipsing top line revenue. Instead of dividends, they're "returning" surplus to the community in the form of more services. Do-it-yourself health care in the form of medical tourism, concierge physicians is a growing threat. And the system is starting to see incentives that help its customers to use less of what it's selling.

Is the PHB being naïve? You be the judge.

CMS Succumbs to Disease Management Style Spin?

If, thanks to the medical home or disease management, you've witnessed the improvements in patients' care, you've also probably been frustrated by those silly skeptics' insistence on validation. But for traditional research designs, statistical significance, valid comparators and publication in obscure scientific journals, the face validity of nurse-led care management for high risk patients could have ushered in a new era in primary care.

Darn those academic-actuary-statistician-weenies! And double darn CMS for falling for them and not funding the medical home and disease management!

Which is why Population Health Blog readers may enjoy this bit of peer-review schadenfreude. It appears a recent CMS pronouncement that its own "Partnership for Patients Program" prevented early elective deliveries and reduced readmissions is highly suspect, thanks to "a weak design, a lack of valid metrics, and a lack of external peer review for its evaluation." 

Yikes.

It appears the amateurs at CMS used a pre-post design, selected start and stop evaluation points to gin up the outcomes, relied on imperfect administrative data and never bothered with having its outcomes validated by independent review. As a result, we really don't know if the billion of dollars that went into PPP did any good at all.

The PHB appreciates the point. Scientific discipline and peer review go a long way making sure that consumers are getting their money's worth. Now that CMS has gone from an agnostic payer to the centerpiece of health reform, there's a huge risk that its bureaucrats will succumb to shortcuts and spin.

Taxpayers deserve better.  And so do patients.

Just What Is "Patient Engagement" in Health Care?

According to this paper by Barello et al in the Journal of Participatory Medicine, the muddled answer depends on when it was used as well as your professional background.

Using a densely written "lexicographic qualitative analysis" to dive into over 250 scientific papers, the authors found that the term has evolved and may still be in its infancy. When it first began to regularly appear about 15 years ago, the term "patient engagement" was used in behavioral and nursing contexts to describe a dimension of established one-on-one provider-patient care.  Since then, it's been used in a biomedical sense to portray a new relationship between a system and a patient.

The authors point out that how "engagement" is achieved depends on a spectrum of patient perspectives that range from unaware to really motivated.  The Population Health Blog suggests that one way to think about it may be the transtheoretical "readiness to change" model.

The one thing that has been missing in the scientific papers is the patients' perspective.  Ironically, no one has asked and cataloged their answers in any systemic manner.

Last but not least, it's unclear if real purpose of achieving patient "engagement" is greater autonomy, relationship-building, making health care more responsive, reducing costs, or improving public health.  As a result, it's a catchphrase has become all things to all people.

While this lacks the all-important input of folks like this and may also be an exercise in tautology, the Population Health Blog managed to extract something of a definition for the term: a span of cognitive processes that seeks participation, compliance, learning  and self-management in health care, including disease, prevention and health.

Doubling Down on Accountable Care Organizations and Health Information Networks

Want to achieve effective health care, reduced costs, increased quality, population health, widespread prevention and seamless health information access? 

It's easy, says  this article in Population Health Management: mix one part PHO with one part HRB to create a HAPPI.

The Population Health Blog was confused too, but that's what's proposed by three smart academics from Johns Hopkins, Arizona State University and UC Berkeley.

As the PHB understands it, Population Health Organizations (PHOs) would be responsible for all medical, public health, community and social services in a defined geographic area and coordinate them with local education, housing and labor. Much of it would be paid for by a pooled risk-adjusted global or capitated payment (budget) from all insurers.

Each organization would be paired with a Health Record Bank (HRB), which would act as a huge data warehouse that not only stores all medical information, but any other publically available information on every individual enrolled in the PHO. The HRBs would be owned and operated by "trusted custodial organizations." Data access would be ultimately controlled by each patient.

The authors believe that patient payments would be a source of additional revenue for their PHOs. Examples include buying "apps" that are tailored to their individual health needs, or selling their personal health information, especially if it means helping physicians buy an electronic health record or access cutting edge research.

Combine a PHO and HRB and you have a Health and Prevention Promotion Initiative (HAPPI). Its size and scale would warrant contributions from community and provider organizations "without the need for additional reimbursement or outside funding." It would efficiently "align incentives" for insurers, hospitals and ACOs - with money left over for prevention, care coordination, decision support and a learning health system.

Breathtaking, isn't it?  If any PHB readers thought accountable care organizations (ACOs) and health information networks (HINs) weren't big enough, along comes Tyrannosaurus rex-sized PHOs, HRBs and HAPPIs. 

The PHB worries that while we'd want to see how pint-sized ACOs (not a slam dunk) and HINs (likewise not a slam dunk) perform before we apply the massive steroid doses, the opposite could happen: their messy failure could be just the justification for doubling down and going even bigger

As pointed out in a recent Wall Street Journal Notable and Quotable:

Economist Michael Munger writing in the Freeman, Aug. 11:

When I am discussing the state with my [academic] colleagues, it's not long before I realize that, for them, almost without exception, the State is a unicorn. I come from the Public Choice tradition, which tends to emphasize consequentialist arguments more than natural rights, and so the distinction is particularly important for me. My friends generally dislike politicians, find democracy messy and distasteful, and object to the brutality and coercive excesses of foreign wars, the war on drugs, and the spying of the NSA.
 
But their solution is, without exception, to expand the power of "the State." That seems literally insane to me—a non sequitur of such monstrous proportions that I had trouble taking it seriously.
 
Then I realized that they want a kind of unicorn, a State that has the properties, motivations, knowledge, and abilities that they can imagine for it. When I finally realized that we were talking past each other, I felt kind of dumb. Because essentially this very realization—that people who favor expansion of government imagine a State different from the one possible in the physical world—has been a core part of the argument made by classical liberals for at least three hundred years.

17 Reasons Why Care Management Is Probably Not Going To Be in a Clinic Near You Anytime Soon

Here's a good review of all the reasons why care management has not become a routine part of patient care. 

As policymakers, reformists, consultants and architects plan for a population and outcomes-based future, they'd be wise to think about the review's 17-point reality check.

1) Start-up costs are considerable;

2) Costly to maintain;

3) Multi-year time horizon for any return on investment;

4) Any success undercuts future traditional fee-for-service revenue;

5) Can't be broken down into discreet 'reimbursible" units for fee-for-service payments;

6) It's paid for with still-novel-experimental capitated payments and/or shared savings;

7) The link between increased quality today and downstream savings tomorrow is still tenuous;

8) Complicates primary care by introducing more uncertainty;

9) Non-physician manager training is time-consuming and costly;

10) It's a resource that is best reserved for high risk patients, not all patients;

11) Doesn't fit into long-standing clinical workflows in established clinics;

12) Primary care already has enough challenges and implementing care management is not a priority;

13) Most EHRs are not configured to document or support non-physician care;

14) Decision-makers need additional information on expected net savings;

15) It relies on a lot of outside-the-doc-comfort zone behavioral, vs. "medical" health interventions;

16) It requires considerable data support;

17) It's often balkanized by multiple payers.

But be of good cheer. Jimmy Cliff reminds us that half the battle is knowing what you're up against.
