Simulation-based training with a focus on non-technical skills can have a positive influence on safety relevant attitudes of participants. If an organization succeeds in training sufficient staff, it may experience a positive change in the safety climate. As the effects of a single training are of a transient nature, annual training sessions may lead to an incremental improvement of safety relevant attitudes of employees over time. In spring 2012 the Department of Anesthesia at the University Hospital of Erlangen established an annual simulation-based training for staff members (e.g. consultants, trainee anesthetists and nurse anesthetists).The study aimed to test whether an annual simulation-based training would result in an incremental longitudinal improvement in attitudes towards teamwork, safety and stress recognition.A survey comprising three domains (teamwork climate, safety climate and stress recognition) of the safety attitudes questionnaire (SAQ) and items addressing briefing and speaking up was distributed to all participants in an annual in-house simulation training. Participants filled out the questionnaire in the morning of each training day. The attitudes were measured before the first training series in 2012, 6 months after the first training and then every year (2013-2016). Participants generated a personalized identification code which allowed individuals to be anonymously tracked over time. Results of the 5‑point Likert scale were transformed to a 100-point scale. Results were calculated at the group level and at the individual level. Univariable linear regression was used to calculate mean changes per year.Over a period of 5 years (2012-2016) a total of 255 individuals completed the questionnaire. Each year, 14-20% of all nurse anesthetists and 81-90% of all anesthetists participated in the simulation-based training. As a result of annual staff turnover 16-24% of participants were new staff members. A personalized code allowed the before and after comparison of 99 staff members who had participated twice or more. Physicians had a higher mean score for teamwork climate before the first training (+8.7 p 0.001). Mean teamwork climate and safety climate scores before the first training increased over a period of 5 years (3.11 for teamwork climate, p 0.001 and 2.73 for safety climate, p 0.001). Repeat participation led to a bigger mean change of individual attitudes in nurse anesthetists: teamwork climate 5.2 (nurses) vs. 1.4 (physicians) and safety climate 5.3 (nurses) vs. 2.8 (physicians) without reaching significance. Participants acknowledged the importance of briefings but confirmed their existence in less than half of the cases. The frequency of briefings increased over the 5‑year period. There were no changes in attitude towards speaking up.Over a 5-year period, small positive changes in attitudes towards teamwork and safety occurred. Low participation of nurse anesthetists as well as personnel turnover may have weakened the impact of simulation-based training on the safety climate. |
