How my PCP alerted me to the potential for abuse in telehealth

by Tom Liu

I recently called my primary care physician (PCP) for the first time in years to get my immunization records, and encountered a strange message saying he was not currently seeing patients. My mom had apparently encountered the same message weeks ago. “Maybe he retired,” she suggested.

I did a quick google search of my PCP’s name to find an alternate contact number, and instead found a shocking article from the local newspaper. Apparently my PCP has been indicted for falsifying tax returns and participating in an online pharmacy organization that provided prescription drugs without an in-person physician examination.

Remote Prescribing: Lucrative, Pervasive, and Very Illegal

I did a quick search online and confirmed that the practice of offering prescription drugs through a “cyber doctor” prescription, relying only on a questionnaire is indeed very illegal.

It is also very pervasive. The National Association of Boards of Pharmacy (NABP) reviewed 10,700 websites selling prescription drugs and found that 97% of them were “Not Recommended”. Of these, 88% do not require a valid prescription and 60% issue prescriptions per online consultation or questionnaire only.

What struck me was how this appeared to be a case where the market came together to produce a “triple win” for profit-seeking internet pharmacies, shady physicians (such as my own), and a subset of patients willing to pay a premium to access drugs (most commonly weight loss drugs, erectile dysfunction drugs, and commonly-abused antidepressants and painkillers).

According to one analysis, one such website offering prescriptions from its own doctors listed prices for fluoxetine (brand name Prozac) and alprazolam (brand name Xanax) that were roughly 400% to 1800% higher than prices from a more traditional Internet pharmacy not offering prescriptions. The fact that such “remote prescription” websites remain in business despite the huge price differential suggests that they are attracting patients willing to pay that premium to avoid seeing their regular doctor. And as for where that money is going—well, my doctor was alleged to have received roughly $2.5 million over six years.

Similar Incentives Could Exist for Telehealth Writ Large

Given the clear business case driving abuse in this model of “remote prescribing”, I wondered about the risks of overuse and abuse in the rapidly burgeoning field of telehealth more broadly. After all, one of the promises of telehealth is its ability to make the delivery of services more convenient for both patients and providers. A physician could vastly expand the number of patients he/she sees without leaving the office—which has been identified as a potent way to alleviate the physician shortage problem.

But that would only hold true if the proliferation of telehealth does not generate additional, potentially unnecessary demand. And substantial evidence points to the presence of physician-induced demand under a fee-for-service system. Currently, Medicare pays for a limited set of telehealth services under the same fee-for-service payment model used for in-person visits. Within Medicaid, while select states are experimenting with bundled or capitated payments that include telehealth, others are retaining their fee-for-service model.

In a testimony before the House Energy and Commerce Committee last month, Dr. Ateev Mehrotra, an expert on telehealth, noted, “To reduce health care costs, telehealth options must replace in-person visits.” I’m not convinced this is the case—especially when there is a clear financial incentive to provide more care.

“The very advantage of telehealth, its ability to make care convenient, is also potentially its Achilles’ heel. Telehealth may be ‘too convenient.’” — Ateev Mehrotra

In some cases, fee-for-service payments for telehealth may result in outright fraud, as my physician may have done. In others, it may simply encourage providers to err on the side of providing more care given uncertainties in a practice environment. In fact, a study led by Dr. Mehrotra found that PCPs were more likely to prescribe antibiotics during e-visits than in-person visits.

As various constituencies continue to debate the best approach for paying for telehealth, it is imperative for us to better understand how the incentives and convenience of telehealth interact to affect overall utilization. Blindly carrying our existing fee-for-service system into the new world of telehealth options may produce some unintended consequences.

Is “progress” in medical education backfiring?

by Karan Chhabra

A good bit of fuss surrounds the evolution of medical education. The way we’re taught sometimes seems as susceptible to trends than the clothes we wear—one decade trumpets the “integrated,” systems-based curriculum, the next decade moves to the “flipped classroom,” and the cycle continues. Of course, these changes are based on educational theory, and their outcomes are often studied rigorously. But every now and then, when I rotate with a doctor trained the old-fashioned way, I wonder what has really been gained—and whether something has been lost—since the days they were taught.

I’ve seen how older physicians recollect tidbits from their preclinical years (decades ago) that my classmates and I can’t seem to remember past a few months. I wonder how much of this is the result of the way they were taught. Of course, there are many confounders here: our own intelligence versus those physicians’, our generation’s perpetual state of distraction, and perhaps the volume of material we’re expected to retain. The “old way” of teaching by discipline (anatomy, pathology, pharmacology, etc.) seems far less intuitive than the way we’re currently taught, by organ system (cardiovascular, gastrointestinal, etc.). To mentally switch from psoriasis to anti-arrhythmics in the same day seems like work.

But that may in fact be the secret to its success. I’m referring to research on “massed practice,” rapidly learning subjects en bloc, as opposed to “interleaved practice,” switching between learning tasks rapidly and revisiting the same topics day after day. A recent article (thanks Skeptical Scalpel) shows a relevant example:

 

Consider this study of thirty-eight surgical residents. They took a series of four short lessons in microsurgery: how to reattach tiny vessels… Half the docs completed all four lessons in a single day, which is the normal in-service schedule. The others completed the same four lessons but with a week’s interval between them.

 

…The difference in performance between the two groups was impressive. The residents who had taken all four sessions in a single day not only scored lower on all measures, but 16 percent of them damaged the rats’ vessels beyond repair and were unable to complete their surgeries.

 

Why is spaced practice more effective than massed practice? … Rapid fire practice leans on short-term memory. Durable learning, however, requires time for mental rehearsal and the other processes of consolidation. Hence, spaced practice works better. The increased effort required to retrieve the learning after a little forgetting has the effect of retriggering consolidation, further strengthening memory.

 

This effect isn’t limited to technical skills. The article also references cognitive tasks, like geometry problems. I wonder if it’d extend to preclinical medical education as well. I can personally relate to how a disease seen in one organ system, say in November, may literally never be seen again under an “integrated” curriculum.  It’s far easier to learn the pathogenesis of strokes and their treatment in the same week—but easier is not always better. Perhaps a trickier, thornier learning process is also sticker in the long run.

Saving money in healthcare, PCMH edition

by Allan Joseph

I wanted to quickly follow up on Tom’s excellent post from yesterday on patient-centered medical homes (PCMHs), which nicely outlined some conflicting results from recent research on the model. (Edited to complete the sentence.)

It really shouldn’t surprise us that PCMHs only saved money in the 10% of patients with the highest risk. Why? Take a look at this chart from the NIHCM, which is one of my favorites in all of health policy:

Distribution of Healthcare Spending

Notice that the top 10% of spenders (not the same as the top 10% of risk scores, but pretty close) account for just about two-thirds of healthcare spending. The vast majority of patients account for very little spending — there’s no savings to be had there. Healthcare spending is highly concentrated at the top.

Now let’s look at spending from another angle. According to the Robert Wood Johnson Foundationtwo-thirds of healthcare spending is on patients with multiple chronic conditions. That means at minimum, roughly one-third of healthcare spending in America is spent on those patients in the top 10% with multiple chronic conditions. (To get even deeper, at least 16% of spending is on patients in the top 10% with three or more chronic conditions.) Of course, that’s only a lower bound — I’d be surprised if the number wasn’t much higher.

So what does this have to do with PCMHs? Well, the core idea behind a PCMH is greatly increased care coordination. That’s precisely the type of intervention that will help sick patients who have multiple chronic diseases — or the very group that accounts for a huge portion of our healthcare spending. No wonder the investment in PCMHs paid off for the sickest patients. They’re the ones where all the money to be saved is.

Given that the vast majority of patients who might use PCMH services account for little health spending, we should expect spending money to build a broad PCMH structure to save money on net. Nor should we be surprised that there’s money to be saved by better coordinating the care of the sickest patients. That’s the whole idea of the “hotspotting” movement. That’s also why Tom was spot-on to focus on the idea of “risk-adjusted population health,” such as focusing care managers on the sickest patients or designing separate clinics that focus exclusively on high-risk patients.

Sometimes it’s worth stepping back and taking stock of our intuitions about what might reduce healthcare costs. If an intervention isn’t aimed at the sickest patients, it’s probably not going to save a lot of money. Don’t be surprised when it doesn’t.

PCMHs Don’t Work—Or Do They? Insights from Two Recent Studies (Of the Same Program)

by Tom Liu

A month ago, a JAMA study rocked the health wonk world by showing provocative evidence that Patient-Centered Medical Homes do not work. Evaluating 32 practices in the PA Chronic Care Initiative over a three-year period (2008-2011), the authors found that achieving NCQA PCMH recognition did not statistically reduce utilization or costs, and only improved one of 11 quality measures (nephropathy screening for diabetes). Aaron Carroll summarized the study and accompanying editorial over at The Incidental Economist. Mainstream media and health wonk blogs alike declared the death of the “touted medical homes model”.

That’s why I was surprised to read this headline last week:

Study: Medical homes cut costs for chronically ill members

The punch line: these two studies evaluated the same PA pilot project over the same time period (albeit with different practices and patient populations).

 

Medical Homes Work—But Only for High-Risk Patients

A close read of the studies reveals that their conclusions are not incongruous. Indeed, the more recent AJMC study found no significant decrease in utilization or costs across all patients, just as the JAMA study did. However, when the authors limited their analysis to the top 10% highest risk patients (defined by DxCG risk scores), they found significant decreases in inpatient utilization in all three program years, and significant decreases in costs in the first two.

We can’t discern if the JAMA study would’ve found the same significant effects if they did a sub-analysis of the highest risk patients. (Interestingly, they state in the Methods section, “we repeated our utilization and cost models among only patients with diabetes,” but the results of that analysis are nowhere to be found.)

These results underscore an insight that’s becoming increasingly clear: cost savings from care management are concentrated in the highest risk individuals.

But we can go one step further.

 

Cost Savings Came ONLY From High-Risk Patients

Among the 654 high-risk patients, the PCMH produced adjusted savings of $107 PMPM in the first year. That roughly comes out to an estimated $69,978 in overall savings. Almost all of this (and then some) came from an estimated 40 avoided hospitalizations (654 patients x 61 adjusted avoided hospitalizations / 1000 patients).

Among 6940 patients overall, the PCMH produced (statistically insignificant) adjusted savings of $10 PMPM in the first year—an estimated $69,400 in overall savings. Across this entire patient group there were an estimated 41-42 avoided hospitalizations.

In other words, this study didn’t just find that savings are concentrated among high-risk patients. Essentially all of the cost savings and avoided hospitalizations came from the top 10% high-risk patient cohort.

This doesn’t mean that other PCMH models couldn’t squeeze savings out of lower risk patients. It just means that this and many existing models haven’t found out how to.

 

How to Achieve “Risk-Targeted Population Health”?

That finding raises a broader question that these studies can’t answer: What prevented the hospitalizations among the high-risk patients, and more importantly, were those key interventions limited to only the high-risk patients?

For example, were the crucial interventions ones that were only used for high-risk patients, such as a dedicated care manager, targeted outreach messages, and special appointments for high-risk patients?

Or were they interventions that were indiscriminately used on all patients, such as standard patient education or practice-level infrastructure that all patients enjoyed (even if only high-risk patients “benefited” in terms of reduced hospitalizations)?

This question is important because all interventions (and the infrastructure to support them) have a cost. Developing patient registries, expanding EHR capabilities, maintaining after-hours access, and investing in new training all represent substantial financial investments. Less than $70,000 in savings among high-risk patients—while extremely meaningful and significant—would be wiped out by the $20,000 “practice support” and average $92,000 bonuses paid out to each PCP by the medical home program.

If all of the benefits and savings are coming from the high-risk patients, we need to devise ways to concentrate our costs as well. Implementing such “risk-targeted population health” may be the only way to make the financials work.

Some practices are trying to do this by using dedicated care managers for high-risk patients within their existing patient panels. Others are trying to create separate clinics entirely dedicated to high-risk patients—which would allow them to limit fixed costs to high-risk patients as well. In fact, the NHS in England announced this January they are piloting this latter approach, creating “complex care practices” of 400-500 high-risk patients drawn from surrounding practices.

Whichever approach proves most effective, one thing is clear from these two studies: we need to rethink our current PCMH model.

Walking uphill both ways

by Allan Joseph and Emily Flower

Sometimes, good data visualization just has a way of grabbing your attention. That’s what the Providence Plan, a data-focused organization here in Rhode Island, was able to do last week with this stark map (click to see a larger version):

Current Busing Policy Maps

Some background: These maps represent the distances high school students have to walk before qualifying for access to free transportation services through the Providence Public School District (PPSD). Or in layman’s terms, if you live in a green area on your high school’s map, you get a free bus pass. If you live in the red area, you’re on your own. A monthly pass costs $62 a month, and that’s the cheapest option.

Middle school students in PPSD receive transportation services if they live more than 1.5 miles from their school. When students transition to high school (when they can pick their school based on their interests), they get a free bus pass only if they live more than 3 miles away — measured as the crow flies, not in walking distance.

It may be cliché, but more than a handful of students do actually walk uphill, both ways, during their often hour-long commute to and from school each day. The city is built primarily on two hills; it’s difficult to get anywhere here without traversing a highway, waterway, or climbing up or down a hill — often all three in the same walk.

For many students, this daily trek is enough of a reason to not attend school. Between middle school and high school, the transportation requirement doubles. So does the chronic absenteeism rate. The chronic absenteeism rate jumps too. (Edited for miscalculation.) PPSD middle schools see a 26% chronic absenteeism rate, defined by a student missing 18 instructional days (roughly the entire month of November). PPSD high schools reported a 36% chronic absenteeism rate in the 2012-2013 school year. Obviously that’s not exclusively due to the transportation issue, but it doesn’t seem like a stretch to say that buses are a major factor — especially since absence rates are sky-high in the winter, even compared to neighboring districts.

But this isn’t just about chronic absenteeism, nor is it limited to education policy. Schools are some of the most important forces for health in the life of poor children — and with 83% of students in PPSD qualifying for subsidized lunch (family income below 185% of the federal poverty level), the majority of students in PPSD are poor or near-poor. In the short term, many students depend on subsidized lunch for food security. Their most familiar and important healthcare provider? The school nurse. Their easiest access to health resources? The school nurse, again. When they don’t go to school, they’re cut off from all of those resources. That’s not to mention that if they do decide to walk to school from nearly 3 miles away as the crow flies, they could be placing their health at risk, as frostbite, heatstroke, and violence are all real risks at various times of the year.

Long-term, there’s a relationship between educational attainment and health outcomes. Though the literature isn’t clear on how much of that is causal, we think it’s a fair bet that students who do better in school (by attending more often) will have a better chance at attaining better health. (Here’s some tentative evidence.)

But there’s some movement towards changing the policy. Recently-introduced House Bill 7012 aims to change the policy in order to bring PPSD’s policy in line with the other school districts in the state: a 2-mile walk zone. That’s far from ideal, but it’s certainly an important step: about 2,100 students would gain access to busing, and it stands to reason that those are the students who would most benefit from expanded busing, as they live the farthest away. Here’s what the new maps would look like (again, click to enlarge):

New Policy Maps

As you can see, that one mile covers quite a bit of the city. But H.B. 7012 isn’t an easy sell, not by a long shot. For one, the policy would cost the city $1.35 million at a time of strict belt-tightening in the Ocean State. But look at it another way: Gov. Lincoln Chafee’s latest budget proposed a large cut to Medicaid — to $819 million in state spending, or $1.9 billion when federal matching funds are added. The policy would cost just 0.1% of the Rhode Island Medicaid program’s annual budget. And therein lies the key to understanding the problem.

Targeted, “low-hanging fruit” interventions on the social-service side can help promote health outcomes at relatively low cost. We can, and should, pursue those interventions — and it shouldn’t take a well-made map to draw our attention to them.

We’re not arguing that Rhode Island’s Medicaid program should pay for the busing solution, of course. That would be an admittedly silly ad hoc way to make policy. What we’re trying to say is that healthcare and medical care are not synonyms. What we talk about in “health policy” is often more properly termed “medical care” — how to finance health insurance, the difficulties of narrow networks, how to manage our medical-care costs as a country, etc. But health is affected by more than medical care — and it’s definitely affected by social services, school transportation included. Yet we’ve separated the ways we pay for social services and medical-care services in ways that don’t always make sense. Moreover, bad health limits the ability of poor Rhode Islanders — and Americans — to take advantage of social services designed to give them a leg up, while limited social services can make pursuing health a Herculean task.

Talk about climbing uphill both ways.
