This interrupted time-series study evaluated the impact of multiprofessional scenario-based training on the safety culture and teamwork climate of 3 surgical wards during a time of reduced financial resources. The authors ran 22 team training sessions for teams of 4 to 5 medical and nursing staff over a 4-month period on 3 surgical wards, using 2 scenarios based on a previously successful obstetric training program. Safety culture was measured before and after training using a validated psychometric questionnaire. After training there was a statistically significant improvement in safety culture (P = .036) on the wards. Teamwork climate improved, but the evidence was not as strong (P = .052). Perceptions of hospital management and adequacy of staffing levels showed significant deterioration. Simple, low-resource interventions can have a significant positive impact on safety culture and possibly teamwork climate on surgical wards. This could be of great value in maintaining patient safety at times of financial constraint.
