MedicalResearch.com: What are the main findings of the study?
Dr. Petersen: VA physicians randomized to the individual incentive group were more likely than controls to improve their treatment of hypertension. The adjusted changes over the study period in Veterans meeting the combined BP/appropriate response measure were 8.8 percentage points for the individual-level, 3.7 for the practice-level, 5.5 for the combined, and 0.47 for the control groups. Therefore, a physician in the individual group caring for 1000 patients with
hypertension would have about 84 additional patients achieving blood pressure control or appropriate response after 1 year. The effect of the incentive was not sustained after the washout period. Although performance did not decline to pre-intervention levels, the decline was significant. None of the incentives resulted in increased incidence of hypotension compared with controls. While the use of guideline-recommended medications increased significantly over the course of the study in the intervention groups, there was no significant change compared to the control group. The mean individual incentive earnings over the study represented approximately 1.6% of a physician’s salary, assuming a mean salary of $168,000.
