A study on development and verification of a visual indicator for patient safety culture

我们使用AHRQ（医疗保健研究和质量机构）开发的医院患者安全文化调查（HSOPSC）和延迟时间（根据报告和事件发生日期之间的差异计算）进行患者安全文化调查。然而，HSOPSC调查和滞后时间调查的结果存在差异。使用HSOPSC的结果可能取决于反应率，并且用总体平均积极反应率乘以反应率计算的值与滞后时间有很好的相关性。因此，延迟时间可能指示患者安全文化。然后，需要进一步的研究。

We performed patient safety culture surveys using Hospital Survey on Patient Safety Culture (HSOPSC) developed by AHRQ (Agency for Healthcare Research and Quality) and Lag time which is calculated from the difference between reporting and occurrence date of incident. However, the results between HSOPSC survey and Lag time survey differ each other. The result using HSOPSC might depend on response rate and the value which is calculated by using the overall average positive response rate multiplied by response rate was well correlated with Lag time. Therefore, Lag time might be possible to indicate patient safety culture. Then, further studies will be needed.
