背景：在重症监护病房（ICU）使用之前，了解用于测量患者安全性的仪器的临床特性是很重要的。方法：安全气候调查（SCSu）是由卫生保健改善研究所认可的一种工具，安全文化量表（SCSc）和安全气候平均值（SCM）是SCSu的七个项目的子集，在加拿大四所大学附属icu中进行。所有工作人员，包括护士、专职医疗保健专业人员、非临床工作人员、重症监护人员和管理人员被邀请参加横断面调查。结果：有效率为74%（313/426）。SCSu和SCSc的内部一致性分别为0.86和0.80，而SCM的表现较差，为0.51。由于内部一致性差，因此没有对SCM进行进一步分析。SCSu和SCSc的重测信度为0.92。在最高5分中，SCSu和SCSc的平均（SD）得分分别为3.4（0.6）和3.4（0.7）。3个内科-外科ICU和1个心血管ICU之间没有差异。根据SCSu和SCSc的测量，管理人员比其他员工感受到更积极的安全氛围。这些结果需要谨慎解释，因为管理参与者的数量很少。结论：在这三种仪器中，SCSu和SCSc似乎测量了一种结构，并且足够可靠。未来的研究应检查其他icu中患者安全仪器的特性，包括对变化的响应，以确保它们是患者安全举措的有效结果测量。
Background: It is important to understand the clinical properties of instruments used to measure patient safety before they are used in the setting of an intensive care unit ICU).Methods: The Safety Climate Survey (SCSu), an instrument endorsed by the Institute for Healthcare Improvement, the Safety Culture Scale (SCSc), and the Safety Climate Mean (SCM), a subset of seven items from the SCSu, were administered in four Canadian university affiliated ICUs. All staff including nurses, allied healthcare professionals, non-clinical staff, intensivists, and managers were invited to participate in the cross sectional survey.Results: The response rate was 74% (313/426). The internal consistency of the SCSu and SCSc was 0.86 and 0.80, respectively, while the SCM performed poorly at 0.51. Because of poor internal consistency, no further analysis of the SCM was therefore performed. Test-retest reliability of the SCSu and SCSc was 0.92. Out of a maximum score of 5, the mean (SD) scores of the SCSu and SCSc were 3.4 (0.6) and 3.4 (0.7), respectively. No differences were noted between the three medical-surgical and one cardiovascular ICU. Managers perceived a significantly more positive safety climate than other staff, as measured by the SCSu and SCSc. These results need to be interpreted cautiously because of the small number of management participants.Conclusions: Of the three instruments, the SCSu and SCSc appear to be measuring one construct and are sufficiently reliable. Future research should examine the properties of patient safety instruments in other ICUs, including responsiveness to change, to ensure that they are valid outcome measures for patient safety initiatives.
