The purpose of this study was to examine relationships among 2 Agency for Healthcare Research and Quality measures of hospital patient safety
and quality, which reflect different perspectives on hospital performance: the Hospital Survey on Patient Safety Culture
)—a hospital employee patient safety culture
survey—and the Consumer Assessment of Healthcare Providers and Systems Hospital Survey (CAHPS
Hospital Survey)—a survey of the experiences of adult inpatients with hospital care and services. Our hypothesis was that these 2 measures would be positively related.
We performed multiple regressions to examine the relationships between the Hospital SOPS
measures and CAHPS
Hospital Survey measures, controlling for hospital bed size and ownership. Analyses were conducted at the hospital level with each survey’s measures using data from 73 hospitals that administered both surveys during similar periods.
Higher overall Hospital SOPS
composite average scores were associated with higher overall CAHPS
Hospital Survey composite average scores (r
= 0.41, P
< 0.01). Twelve of 15 Hospital SOPS
measures were positively related to the CAHPS
Hospital Survey composite average score after controlling for bed size and ownership, with significant standardized regression coefficients ranging from 0.25 to 0.38. None of the Hospital SOPS
measures were significantly correlated with either of the two single-item CAHPS
Hospital Survey measures (hospital rating and willingness to recommend).
This study found that hospitals where staff have more positive perceptions of patient safety culture
tend to have more positive assessments of care from patients. This finding helps validate both surveys and suggests that improvements in patient safety culture
may lead to improved patient experience
with care. Further research is needed to determine the generalizability of these results to larger sets of hospitals, to hospital units, and to other settings of care.
