Will Improvements in Patient Experience With Care Impact Clinical and Quality of Care Outcomes? A Systematic Review

Background: Patient experiences with health care have been widely used as benchmark indicators of quality for providers, health care practices, and health plans. Objective: The objective of this study was to summarize the literature regarding the associations between Consumer Assessment of Healthcare Providers and Systems (CAHPS) patient experiences and clinical and quality outcomes. Research Design: A systematic review of the literature was completed using PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature on December 14, 2019. Separate searches were conducted to query terms identifying CAHPS surveys with clinical and quality outcomes of care. Two reviewers completed all components of the search process. Study Selection: Studies investigating associations between CAHPS composite ratings and health care sensitive clinical outcomes or quality measures of care were included in this review. Studies were excluded if they did not investigate patient experiences using CAHPS composite ratings or if CAHPS composites were not treated as the independent variable. Results: Nineteen studies met inclusion criteria, 10 investigating associations of CAHPS composite ratings with clinical outcomes and 9 investigating these associations with quality measures. Patient-provider communication was the most studied CAHPS composite rating and was significantly associated with self-reported physical and mental health, frequency of emergency room visits and inpatient hospital stays, hospitalization length, and CAHPS personal physician global ratings. Conclusions: Ratings of patient experience with care may influence clinical and quality outcomes of care. However, key inconsistencies between studies affirm that more research is needed to solidify this conclusion and investigate how patient experiences differentially relate to outcomes for various patient groups.
