RESUMEN
BACKGROUND: Cognitive Aids (checklists) are a common tool to improve patient safety. But the factors for their successful implementation and continuous use are not yet fully understood. Recent publications suggest safety culture to play a key role in this context. However, the effects on the outcome of implementation measures remain unclear. Hospitals and clinics that are involved in cognitive aid development and research might have significantly different safety cultures than their counterparts, resulting in skewed assessments of proper implementation. Therefore, the objective of this study was to assess the correlation between cognitive aid implementation and safety attitudes of staff members in early adopting and later adopting clinics. METHODS: An online survey of the Safety Attitudes Questionnaire (SAQ) was carried out in German anaesthesiology departments during the initial implementation of a new checklist for emergencies during anesthesia ("eGENA" app). Subsequently an analysis between subgroups ("eGENA" app usage and occupation), with Kruskal-Wallis- and Mann-Whitney-U-Tests was carried out for the general SAQ, as well as it six subscales. RESULTS: Departments that introduced "eGENA" app (Median 3,74, IQR 0,90) reported a significantly higher median SAQ (U (NeGENA = 6, Nnon eGENA = 14) = 70,0, z = 2,31, p = 0,02, r = 0,516) than their counterparts (Median 2,82, IQR 0,77) with significant differences in the dimensions teamwork climate, work satisfaction, perception of management and working conditions. CONCLUSION: Early adopters of cognitive aids are likely to show a significantly higher perception of safety culture in the SAQ. Consequently, successful implementation steps from these settings might not be sufficient in different clinics. Therefore, further investigation of the effects of safety culture on cognitive aid implementation should be conducted.
