HCAHPS Survey Results: Impact of Severity of Illness on Hospitals' Performance on HCAHPS Survey Results.

Background: The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey is used by the Centers of Medicare and Medicaid (CMS) to assess inpatient satisfaction. HCAHPS survey results are publicly reported, and performance began to affect CMS reimbursement to hospitals as of FY2013. However, the impact of severity of illness on patients' self-reported inpatient satisfaction as measured by HCAHPS survey scores remains unknown.
