Quantifying Magnitude of Group-Level Differences in Patient Experiences with Health Care.

OBJECTIVE: Review approaches assessing magnitude of differences in patient experience scores between different providers. DATA SOURCES: 1990-2016 literature. STUDY
DESIGN: Systematic literature review. DATA EXTRACTION
METHODS: Of 812 articles mentioning "CAHPS," "patient experience," "patient satisfaction," "important(ce)," "difference," or "significance," we identified 79 possible articles, yielding 35 for data abstraction. We included 22 articles measuring magnitude of differences in patient experiences. PRINCIPAL
FINDINGS: We identified three main ways of estimating magnitude of differences in patient experience scores: (1) by distribution/range of patient experience variable, (2) against external anchor, and (3) comparing a difference in patient experience on one covariate to differences in patient experience on other covariates.
CONCLUSIONS: We suggest routine estimation of magnitude in patient experience research. More work is needed documenting magnitude of differences between providers to make patient experience data more interpretable and usable. © Health Research and Educational Trust.
