Abstract
BACKGROUND: In 2009, the Centers for Medicare & Medicaid Services (CMS) began publicly reporting 30-day hospital readmission rates for patients discharged with acute myocardial infarction (MI), heart failure (HF), or pneumonia. OBJECTIVES: This study assessed trends of 30-day readmission rates and post-discharge care since the implementation of CMS public reporting. METHODS: We analyzed Medicare claims data from 2006 to 2012 for patients discharged after a hospitalization for MI, HF, or pneumonia. For each diagnosis, we estimated trends in 30-day all-cause readmissions and post-discharge care (emergency department visits and observation stays) by using hospitalization-level regression models. We modeled adjusted trends before and after the implementation of public reporting. To assess for a change in trend, we tested the difference between the slope before implementation and the slope after implementation. RESULTS: We analyzed 37,829 hospitalizations for MI, 100,189 for HF, and 79,076 for pneumonia from >4,100 hospitals. When considering only recent trends (i.e., since 2009), we found improvements in adjusted readmission rates for MI (-2.3%), HF (-1.8%), and pneumonia (-2.0%), but when comparing the trend before public reporting with the trend after reporting, there was no difference for MI (p = 0.72), HF (p = 0.19), or pneumonia (p = 0.21). There were no changes in trends for 30-day post-discharge care for MI or pneumonia; however, the trend decreased for HF emergency department visits from 2.3% to -0.8% (p = 0.007) and for observation stays from 15.1% to 4.1% (p = 0.04). CONCLUSIONS: The release of the CMS public reporting of hospital readmission rates was not associated with any measurable change in 30-day readmission trends for MI, HF, or pneumonia, but it was associated with less hospital-based acute care for HF.
