AbstractThis study evaluates quality performance of hospitals participating in Medicare Shared Savings and Pioneer Accountable Care Organization (ACO) programs relative to nonparticipating hospitals. Overall, 198 ACO participating and 1210 propensity score matched, nonparticipating hospitals were examined in a difference-in-difference analysis, using data from 17 states in the years 2010-2013. The authors studied preventable hospitalizations for conditions sensitive to high-quality ambulatory care-chronic obstructive pulmonary disease (COPD) and asthma, chronic heart failure (CHF), complications of diabetes-and 30-day all-cause readmissions potentially influenced by hospital care. A decrease was found in preventable hospitalizations for COPD and asthma and for diabetes complications for ACO participating hospitals, but no significant differences for preventable CHF hospitalizations and 30-day readmissions. Mixed results may be attributable to insufficient incentives for ACO participating hospitals to decrease 30-day readmissions, whereas disease-focused initiatives may have a beneficial effect on preventable hospitalizations for COPD and asthma and complications of diabetes.
