BackgroundPatient safety incidents are unavoidable and nurses, as parties involved, become second victims due to the incident itself and the way it is handled. In China, reconstructing the course of events is a crucial step in the aftermath of the incident; however, its impact on the emotional well-being of the second victim remains unclear.PurposeThe purpose of this study is to gain insight into the psychological experiences and current conditions of nurses who act as second victims during the process of reconstructing the sequence of events. Additionally, the study aims to provide justifications for supporting these individuals.MethodsAn exploratory mixed research method was adopted to understand the emotional experience of the second victim when reconstructing the passage of the incident through qualitative research. Fourteen nurses with experience as second victims were selected for semi-structured interviews using purposive sampling according to the maximum difference sampling strategy. Through quantitative research, we explored the negative psychology and support needs of the second victims when they reverted to the incident, and a self-developed questionnaire (the Cronbach’s alpha coefficient was 0.895) was used to survey 3,394 nurses with experiences as second victims in 11 tertiary hospitals in Shanxi Province.ResultsIn the qualitative part of the study, the emotional experience of the second victim’s reconstruction of the course of events after a patient safety incident could be categorized into 3 themes: negative views as initial psychological impact, avoidance as part of psychological impact, and expectations and growth in overcoming negative psychological impact. The quantitative part of the study revealed that the emotions of guilt and self-blame accounted for the highest percentage after a patient safety incident. The second victim presented a high score of 39.58 ± 5.45 for support requirements.ConclusionThis study provides a better understanding of the true emotional experiences and the need for support of the second victim in the process of reconstructing the course of events. Following a patient safety incident, nursing administrators and healthcare institutions should consider the adverse psychological effects on the second victim, prioritize their support needs during the incident’s reconstruction, create a positive safety culture, and reduce the risk of secondary victimization for these individuals.
