How the CAHPS Clinician and Group Patient Experience Survey Data Have Been Used in Research: A Systematic Review

Abstract

Purpose: Patient experience is a key aspect of care quality. The Consumer Assessment of Healthcare Providers and Systems Clinician and Group (CG-CAHPS®) survey measures experiences with ambulatory care providers to inform public reporting, pay-for-performance initiatives, interventions, patient choice of physicians/practices, and quality improvement. Since the survey’s 2007 release, no systematic review of its use in research has been published. Methods: We reviewed English-language, peer-reviewed articles published since 2008 using CG-CAHPS survey data in the U.S. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and used the Checklist for Analytical Cross-Sectional Studies. Results: We examined 126 articles and included 52. Twenty-seven articles focused on general primary care, and the others focused on ambulatory specialty care. Of the 52 studies, 37 were cross-sectional, and the majority conducted patient-level regression analysis, controlling for patient characteristics. The most-used CAHPS measures were overall provider rating and the provider communication composite. CG-CAHPS data were primarily utilized to evaluate interventions (24 studies) and examine cross-sectional associations (21 studies) of site-level (eg, organizational climate), provider-level (physician empathy), and patient-level (medication adherence) factors with patient experience. Four studies reported disparities in patient experience. Conclusions: The widespread use of CG-CAHPS data implies the survey’s value in measuring and improving care quality. Unlike facility or plan surveys, the CG-CAHPS survey was designed to allow attribution to medical groups and clinicians, which, as evidence shows, is its main strength. Policymakers, researchers, clinicians, and health care leaders can leverage CG-CAHPS data in quality improvement efforts and interventions supporting patient-centered care.
