Practice-level financial incentives don’t affect BP control

In an examination of the effect of financial incentives on hypertension care at 12 outpatient clinics, financial incentives for individual physicians, but not practice-level or combined incentives, resulted in greater blood pressure control or appropriate response to uncontrolled blood pressure.

None of the incentives resulted in greater use of guideline-recommended medications compared with controls, researchers wrote in the Sept. 11 issue of the Journal of the American Medical Association.

Value-based purchasing systems, such as the one established for Medicare providers by the Affordable Care Act, “are intended to align incentives to promote high-quality healthcare,” the researchers wrote. However, evaluations “of the effectiveness of pay-for-performance programs directed at hospitals have shown contradictory results.”

Methodology

Laura A. Petersen, MD, MPH, of the Veterans Affairs Medical Center and Baylor College of Medicine in Houston, and colleagues conducted a randomized controlled trial to test the effect of explicit financial incentives to individual physicians and practice teams for the delivery of guideline-recommended care for hypertension in the primary care setting.

The trial at 12 Veterans Affairs outpatient clinics with five performance periods enrolled 83 primary care physicians and 42 nonphysician personnel (RNs, nurse practitioners, RN case managers, licensed practical nurses, physician assistants and pharmacists). The interventions were physician-level (individual) incentives, practice-level incentives, both or none.

Intervention participants received up to five payments every four months; all participants could access feedback reports. The primary measured outcomes were the number of patients (among a random sample) achieving guideline-recommended blood pressure thresholds or receiving an appropriate response to uncontrolled blood pressure, the number of patients prescribed guideline-recommended medications and the number who developed hypotension.

Results

Among physicians who participated in all five performance periods, the average total payment over the course of the study was $4,270 in the combined physician and practice-level group, $2,672 in the individual physician-level group and $1,648 in the practice-level group.

Change in blood pressure control or appropriate response to uncontrolled blood pressure compared with the control group was greater only in the individual incentives group. The difference in change in proportion of patients achieving blood pressure control or receiving an appropriate response between the individual incentive and no-incentive group was 8.36%.

Although the use of guideline-recommended medication increased over the course of the study in the intervention groups, there was no change compared with controls.

Far more intervention than control-group participants viewed their feedback reports on the website (67% vs. 25%), suggesting that participants were aware of the relationship between performance and rewards.

“Although concerns about overtreatment have been cited in criticisms of pay-for-performance programs, we did not find a higher incidence of hypotension in the panels of physicians randomized to the incentive groups,” the authors wrote.

Even small reductions in blood pressure translate into significant reductions in morbidity and mortality, and in system-wide costs, the authors noted.

“This trial addresses the needs of policymakers and payers for information about a clinically relevant payment intervention in routine practice,” the authors wrote. “Payment-system interventions are attractive because of their potential scale and reach.

“However, payment-system interventions are only one piece of the solution to improve management of chronic diseases such as hypertension. More resource-intensive, tailored, patient-level self-management strategies may be needed to truly affect patient outcomes.”
