ACOs Do Not Improve Spending or Quality

Thank to Dr. McCanne, I am re-posting the following article from the Annals of Internal Medicine that was published Tuesday. I have written before about MSSPs, so I thought it would be a respite from talking about single payer.

Here is the article in its entirety:

Performance in the Medicare Shared Savings Program After Accounting for Nonrandom Exit: An Instrumental Variable Analysis
By Adam A. Markovitz, BS; John M. Hollingsworth, MD, MS; John Z. Ayanian, MD, MPP; Edward C. Norton, PhD; Phyllis L. Yan, MS; Andrew M. Ryan, PhD

Abstract

Background:
Accountable care organizations (ACOs) in the Medicare Shared Savings Program (MSSP) are associated with modest savings. However, prior research may overstate this effect if high-cost clinicians exit ACOs.

Objective:
To evaluate the effect of the MSSP on spending and quality while accounting for clinicians’ nonrandom exit.

Design:
Similar to prior MSSP analyses, this study compared MSSP ACO participants versus control beneficiaries using adjusted longitudinal models that accounted for secular trends, market factors, and beneficiary characteristics. To further account for selection effects, the share of nearby clinicians in the MSSP was used as an instrumental variable. Hip fracture served as a falsification outcome. The authors also tested for compositional changes among MSSP participants.

Setting:
Fee-for-service Medicare, 2008 through 2014.

Patients:
A 20% sample (97 204 192 beneficiary-quarters).

Measurements:
Total spending, 4 quality indicators, and hospitalization for hip fracture.

Results:
In adjusted longitudinal models, the MSSP was associated with spending reductions (change, −$118 [95% CI, −$151 to −$85] per beneficiary-quarter) and improvements in all 4 quality indicators. In instrumental variable models, the MSSP was not associated with spending (change, $5 [CI, −$51 to $62] per beneficiary-quarter) or quality. In falsification tests, the MSSP was associated with hip fracture in the adjusted model (−0.24 hospitalizations for hip fracture [CI, −0.32 to −0.16 hospitalizations] per 1000 beneficiary-quarters) but not in the instrumental variable model (0.05 hospitalizations [CI, −0.10 to 0.20 hospitalizations] per 1000 beneficiary-quarters). Compositional changes were driven by high-cost clinicians exiting ACOs: High-cost clinicians (99th percentile) had a 30.4% chance of exiting the MSSP, compared with a 13.8% chance among median-cost clinicians (50th percentile).

Limitation:
The study used an observational design and administrative data.

Conclusion:
After adjustment for clinicians’ nonrandom exit, the MSSP was not associated with improvements in spending or quality. Selection effects — including exit of high-cost clinicians — may drive estimates of savings in the MSSP.

Spending Reductions in the Medicare Shared Savings Program: Selection or Savings?
By J. Michael McWilliams, MD, PhD, Alan M. Zaslavsky, PhD, Bruce E. Landon, MD, MBA, and Michael E. Chernew, PhD.

Prior studies suggest that accountable care organizations (ACOs) in the MSSP have achieved modest, growing savings. In a recent study in Annals of Internal Medicine, Markovitz et al. conclude that savings from the MSSP are illusory, an artifact of risk selection behaviors by ACOs such as “pruning” primary care physicians (PCPs) with high-cost patients. Their conclusions appear to contradict previous findings that characteristics of ACO patients changed minimally over time relative to local control groups.

Conclusion

Monitoring ACOs will be essential, particularly as incentives for selection are strengthened as regional spending rates become increasingly important in determining benchmarks. Although there has likely been some gaming, the evidence to date — including the study by Markovitz et al. — provides no clear evidence of a costly problem and suggests that ACOs have achieved very small, but real, savings. Causal inference is hard but necessary to inform policy. When conclusions differ, opportunities arise to understand methodological differences and to clarify their implications for policy.

And finally, Don McCanne’s comment:

This important study in the highly reputable Annals of Internal Medicine concludes that accountable care organizations (ACOs) participating in the Medicare Shared Savings Program (MSSP) did not show any improvement in spending or quality when adjustments were made for selection effects, especially the non-random exit of high-cost clinicians (“I’m worth the extra money, and if you’re gonna cut my fees, I’m outta here.”)

The conclusions were immediately challenged by others in the policy community who have previously published studies indicating that “ACOs have achieved very small, but real, savings,” albeit admitting that “there has likely been some gaming.” And the savings were, indeed, very small. Others have suggested that the very small savings did not take into consideration the significant increase in provider administrative costs for technological equipment and personnel to run the ACOs, and certainly did not consider other unintended consequences such as the tragic increase in physician burnout.

Another problem with the infatuation for ACOs is that politicians and the policy community are insisting that we continue with this experiment in spite of the disappointing results to date. That simply postpones the adoption of truly effective policies, such as those in a single payer Medicare for All program, that would actually improve quality while greatly reducing administrative waste. The tragedy is that this also perpetuates uninsurance, underinsurance, and personal financial hardship from medical bills.

People are suffering and dying while the policy community continues to diddle with ACOs and other injudicious policy inventions. Enough! It’s long past time to reduce suffering and save lives! Single Payer Medicare for All!

(Yes, I’m angry, but even more I’m terribly anguished over the health care injustices that we continue to tolerate through our collective inaction.)

See, we can’t get away from Medicare for All after all.

 

Those Damn Models Again – Health Care As An Experiment in Bait & Switch

Another shout out to Dr. McCanne, who posted today about a study sponsored by the AMA and conducted by RAND that basically said that alternative payment models (APM) are affecting physicians, their practices and hospitals.

Here is the RAND Summary with key findings:

RAND

Effects of Health Care Payment Models on Physician Practice in the United States
By Mark W. Friedberg, et al
This report, sponsored by the American Medical Association (AMA), describes how alternative payment models (APMs) affect physicians, physicians’ practices, and hospital systems in the United States and also provides updated data to the original 2014 study. Payment models discussed are core payment (fee for service, capitation, episode-based and bundled), supplementary payment (shared savings, pay for performance, retainer-based), and combined payment (medical homes and accountable care organizations). The effects of changes since 2014 in the Affordable Care Act (ACA) and of new alternative payment models (APMs), such as the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) Quality Payment Program (QPP), are also examined.
Key Findings
Payment models are changing at an accelerating pace
Physician practices, health systems, and consultants find it difficult to keep up with the proliferation of new models, with some calling for a “time out” to allow them to better adapt to current APMs.
Payment models are increasing in complexity
Alternative payment models have become increasingly complex since 2014. Practices that have invested in understanding complex APMs have found opportunities to earn financial awards for their preexisting quality — without materially changing patient care.
Risk aversion is more prominent among physician practices
Risk aversion among physician practices was more prominent. Risk-averse practices sought to avoid downside risk or to off-load downside risk to partners (e.g., hospitals and device manufacturers) when possible.

Here is the comment by Don McCanne:

There is much more here than a casual glance might imply. The search for value-based payment in health care, as opposed to paying for volume, has led to various payment models such as shared savings, accountable care organizations, bundled payments, pay for performance (P4P), medical homes, and other alternative payment models. How well is that working?
To date, most studies have been quite disappointing. Claims of cost savings are belied when considering the additional provider costs of information technology and human manpower devoted to these models, not to mention the high emotional cost of burnout. This RAND study shows that these models are increasing in complexity, making it difficult for the health delivery system to keep up. Even worse, they are inducing risk aversion. The health care providers are trying to avoid those who most need health care – the opposite of what our health care system should be delivering.
Much of the experimentation in delivery models has been centered around reward or punishment. But, as Alfie Kohn writes, “intrinsic motivation (wanting to do something for its own sake)… is the best predictor of high-quality achievement,” whereas “extrinsic motivation (for example, doing something in order to snag a goody)” can actually undermine intrinsic motivation. It has been observed by others that the personal satisfaction of achievement of patient health care goals is tremendously rewarding, whereas the token rewards based on meager quality measurements are often insulting because of the implication that somehow token payments are a greater motivator than fulfilling Hippocratic traditions. Even more insulting are the token penalties for falling on the wrong side of the bell curve simply as a result of making efforts to care for patients with greater medical or sociological difficulties.
Quoting Alfie Kohn again, “carrots or sticks… can never create a lasting commitment to an action or a value, and often they have exactly the opposite effect … contrary to hypothesis.” The RAND report suggests slowing down and working with these models some more while increasing investment in data management and analysis with the goal of increasing success with alternative payment models. No. These models are making things worse. It’s time to abandon them and get back with taking care of our patients. The payment model we need is an improved version of Medicare that takes care of everyone. Throw out the sticks and carrots.

 

But however we see it, from the point of view of carrots and sticks as not able to change behavior, or by introducing ever newer models of alternative payments, the end result is the same.

Health care suffers because of the wasteful, bureaucratic, and arbitrary imposition of models that only serve to make life for physicians and hospitals harder, and makes health care more expensive and complex.

As Dr. McCanne says above, throw out the carrots and the sticks. Get rid of the models that don’t work and go to a single payer system that is streamlined and less bureaucratic and arbitrary.

Mid-Week Catch-Up

Borrowing a page from another blogger, here are some items that I have seen this week that I did not immediately post to the blog. The first three are courtesy of Medical Travel.com.

From AHA.org, comes an article about the Zika epidemic I wrote about a while ago. About 14% of babies age one or older who were born in U.S. territories to pregnant women infected with Zika virus since 2016 have at least one health problem possibly caused by exposure to the virus, the Centers for Disease Control and Prevention reported today. About 6% had Zika-associated birth defects, 9% nervous system problems and 1% both.

From Health Affairs.org, comes a report about the fundamental flaw of health care and the recurring-payment-for-outcomes solution.

Bloomberg.org reported that US hospitals are shutting at a 30-a-year pace with no end in sight.

Lastly, Health Affairs blog posted an article about an issue I covered some years ago, the Medicare Shared Savings Program (MSSP).

Have a good rest of the week after remembering the fallen of 9/11. FYI, I was in Houston at the time, just having started a new job with Aon there, and heard about the first plane crashing into the north tower while driving to work and listening to the radio. As we were all new, and had little to do, I took a brief siesta and when I went into the hallway, was told to go upstairs to the break room. There was a TV on, and as I entered the room, the south tower went down. This NYC born kid was not sure what was going to happen next, surrounded as I was by all these Texans. I remembered the people and companies I knew there in both towers, especially my cousin who was there for the 1993 attack.
