Exploring relationships between patient safety culture and patients' assessments of hospital care.

OBJECTIVES: 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 (Hospital SOPS)--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. METHODS: 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. RESULTS: Higher overall Hospital SOPS composite average scores were associated with higher overall CAHPS Hospital Survey composite average scores (r = 0.41, P G 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). CONCLUSIONS: 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.

Exploring relationships between hospital patient safety culture and adverse events.

OBJECTIVES: There has been very limited research linking staff perceptions of hospital patient safety culture with rates of adverse clinical events. This exploratory study examined relationships between the Agency for Healthcare Research and Quality's (AHRQ) Hospital Survey of Patient Safety Culture and rates of in-hospital complications and adverse events as measured by the AHRQ Patient Safety Indicators (PSIs). The general hypothesis was that hospitals with a more positive patient safety culture would have lower PSI rates. METHODS: We performed multiple regressions to examine the relationships between 15 patient safety culture variables and a composite measure of adverse clinical events based on 8 risk-adjusted PSIs from 179 hospitals, controlling for hospital bed size and ownership. All patient safety culture data were collected in 2005 and 2006 (except 1 late 2004 hospital), and all PSI data were collected in 2005. RESULTS: Nearly all of the relationships tested were in the expected direction (negative), and 7 (47%) of the 15 relationships were statistically significant. All significant relationships were of moderate size, with standardized regression coefficients ranging from -0.15 to -0.41, indicating that hospitals with a more positive patient safety culture scores had lower rates of in-hospital complications or adverse events as measured by PSIs. CONCLUSIONS: Our findings support the idea that a more positive patient safety culture is associated with fewer adverse events in hospitals. Further research is needed to determine the generalizability of these results to larger sets of hospitals and to examine the causal relationship between patient safety culture and clinical patient outcomes.

Anticipation of monetary gain but not loss in healthy older adults.

Although global declines in structure have been documented in the aging human brain, little is known about the functional integrity of the striatum and prefrontal cortex in older adults during incentive processing. We used event-related functional magnetic resonance imaging to determine whether younger and older adults differed in both self-reported and neural responsiveness to anticipated monetary gains and losses. The present study provides evidence for intact striatal and insular activation during gain anticipation with age, but shows a relative reduction in activation during loss anticipation. These findings suggest that there is an asymmetry in the processing of gains and losses in older adults that may have implications for decision-making.
