This research aimed to develop a safety system model to prevent infection in operating theatre nursing department at Rajavithi Hospital using a mixed-method design. The study composed of 3 phases: Phase 1: study of the current situation; Phases 2: model development; Phases 3: evaluation of the outcomes of the model. Data were collected using a literature review and evidenced-based practice, a focus group, a record, observations, and questionnaires. Qualitative data were analyzed using content analysis, while quantitative data were analyzed using frequency, percentage, mean, standard deviation and paired t-tests. The results found that the safety system model to prevent infection in the operating theatre nursing department composed of 3 phases. Phase 1: Pre-operation, which consisted of 5 components, including a pre-operative care at the ward, a patient visit before the operation, preparation of the operating room, preparation of personnel for the operation, and preparation of patients when they come to the operating rooms. Phase 2: Intra-operation, which consisted of 1 component which was nursing care during the operation. Phase 3: Post-operation, which consisted of 2 components, namely, the post-operative period in the operation room and post-operative period in the ward. After implementing the model, 99.20% of personnel were able to follow the model. There were no incidents of surgical site infection and no incidents of injury to personnel. Patients who received nursing care using the model reported a moderate level of satisfaction (Mean=35.79) at the first time of implementation, and a high level of satisfaction (Mean=37.93) at the second time of implementation. Personnel reported a moderate level of satisfaction for using the model, both at the first and second time of implementation. However, satisfaction of the second imple­mentation was significantly higher than the first implementation at p=.01. In conclusion, the model was tested to be effective to reduce surgical site infections and injury to personnel.
