Dataset: Consumer Assessment of Healthcare Providers and Systems (CAHPS) - Adult Hospital Survey (Adult HCAHPS)

Basic Information
Dataset Full Name Consumer Assessment of Healthcare Providers and Systems (CAHPS) - Adult Hospital Survey
Dataset Acronym Adult HCAHPS

The Adult HCAHPS survey asks people aged 18 and over to report their recent experience of inpatient care. The purpose of the HCAHPS is to provide patient feedback that can be used for institutional quality projects and rating the quality of inpatient facilities. It includes 10 measures of patient experience including 6 composite measures, two individual items and two global ratings.

Information from HCAHPS is also aggregated for star ratings in Medicare's Hospital Compare database.

The Centers for Medicare & Medicaid Services (CMS) is responsible for implementing the study and it is used in both quality reporting and value-based purchasing decisions.

Data Collection Frequency


Strengths and Limitations
  • Comparable data collected across most US hospitals
  • Multiple modes available for survey completion increases response rates
  • Patient-centered outcome measures
  • Strong incentive for hospital participation due to value-based purchasing 
  • Vendors must be CMS approved to conduct the survey, increasing quality
  • Surveys are aggregated by hospital, patient-level data is not available
  • Some survey questions have changed over time (ie pain items)
  • Approximately a 30% survey response rate
  • No clinical correlation of patient reports
  • Designed for acute-care hospitals only, majority of specialty hospitals are excluded
