Abstract: Objective: To construct a support strategy for the second victim of nurses when restoring the process of patient safety incidents. Methods: Guided by the theory of social support, the semi-structured interview method and questionnaire survey method were used to clarify the feelings and needs of nurses when restoring the event after the patient safety incident, and the special group discussion method was used to form a pool of support strategies for the second victim during the restoration process. The Delphi method was used to conduct two rounds of correspondence with 16 experts to provide opinions and suggestions from different levels and perspectives. Results: The study formed a support strategy for the second victim of nurses during the restoration process after a patient safety event (referred to as "EAERI support strategy for restoration events"), including 5 support items, 11 support contents and 32 support methods. The recovery rates of the effective questionnaires for the two rounds of expert correspondence were 90.0% and 88.9% respectively, and the expert authority levels were 0.88 and 0.94 respectively. The Kendall harmony coefficients of experts were 0.13 and 0.26 respectively (P<0.01). Conclusion: The formation process of EAERI support strategy is scientific and normative, which can be used as a tool for nursing managers to support the second victim when restoring the incident.
