Medicaid Stage 1 Meaningful Use EHR Incentive Payments Are Associated With Higher Quality but Not Improvements in Quality.

This was a retrospective cohort study of ambulatory care quality by physicians who received payment for Medicaid Stage 1 Meaningful Use (MU) in 2012 using New York State Medicaid Claims (2010-2013). Eight quality measures were used to compare performance of physicians who received payments to Adopt, Implement, or Use (AIU) an electronic health record in 2011 but not for MU in 2012 (AIU-only group) and physicians who cared for Medicaid patients but received no payments (no-incentive group), using propensity score-weighted difference-in-difference logistic regression analyses, clustering by physician. In all, 13 697 physicians and 913 476 patients were studied. In 2010, the MU group scored higher than both groups (vs AIU-only in 3 of 8 measures, 0.8-1.3 adjusted percentage points; vs no-incentive, 2 of 8 measures, 0.9-2.0 adjusted percentage points). The difference-in-difference analysis found no additional improvements in quality over time relative to either control group. Longer follow-up is needed to determine the effects of Stage 2 MU.
