RESUMO
We conducted a cross-sectional study of patient safety culture aimed at examining the factors that influence patient safety culture in university hospitals under a universal health insurance system. The Hospital Survey on Patient Safety Culture developed by the Agency for Healthcare Research and Quality was used. The survey was distributed to 1066 hospital employees, and 864 responded. The confirmatory factor analysis showed a good fit of the results to the 12-composites model. The highest positive response rates were for "(1) Teamwork within units" (81%) and "(2) Supervisor/manager expectations and actions promoting patient safety" (80%), and the lowest was for "(10) Staffing" (36%). Hayashi's quantification theory type 2 revealed that working hours per week had the greatest negative impact on patient safety culture. Under a universal health insurance system, workload and human resources might have a significant impact on the patient safety culture.

AIMS: The purpose of this study was to determine the reliability and validity of the Japanese version of the Richards-Campbell Sleep Questionnaire as a measure of sleep among intensive care unit patients in a Japanese hospital. DESIGN: Cross-sectional survey. METHODS: The Richards-Campbell Sleep Questionnaire was initially translated into Japanese using the back-translation method. Validity was evaluated by determining the association between sleep efficiency, measured using simplified polysomnography, and the total score on the Japanese version of the Richards-Campbell Sleep Questionnaire. Adult non-intubated intensive care unit patients who completed the five-item visual analogue scale underwent polysomnography for one night. Reliability was tested using Cronbach's alpha coefficient. RESULTS: Thirty-three patients were included in the analysis. After excluding four patients with subsyndromal delirium, the Pearson correlation coefficient was 0.602 (p = 0.001). Cronbach's alpha coefficient was 0.911. CONCLUSION: The Japanese version of the Richards-Campbell Sleep Questionnaire could be used as an alternative to polysomnography when assessing sleep quality in lucid intensive care unit patients.
