Do readmissions count as an outcomes measure? The Centers for Medicare and Medicaid Services lists them among its Outcomes Measures here. QualityNet.org elaborates further:
The Centers for Medicare & Medicaid Services (CMS) 30-day readmission measures assess a broad set of healthcare activities that affect patients’ well-being. Patients who receive high-quality care during their hospitalizations and their transition to the outpatient setting will likely have improved outcomes, such as survival, functional ability, and quality of life.
The public reporting of 30-day risk-standardized readmission measures is consistent with the priorities of the Department of Health and Human Services’ National Quality Strategy, which aims to: a) improve health care quality; b) improve the health of the U.S. population; and c) reduce the costs of health care.
