OBJECTIVEThis review aimed to examine the impact of patient suicide on health care professionals (HCPs), assess available support resources, and evaluate postvention (i.e., activities designed to support HCPs after a patient suicide) efforts.METHODSAn integrative systematic review was conducted to evaluate the prevalence of patient suicide and its emotional and professional impacts on HCPs. Searches were conducted in MEDLINE, Embase, CINAHL Plus, and the Cochrane Library in October 2021 and August 2022. Index terms and keywords were related to suicide, patients, and clinicians. Each article was assessed for quality with the Mixed Methods Appraisal Tool.RESULTSSixty-six relevant articles were identified. Across studies, the mean±SD percentage of HCPs who experienced a patient suicide was 51%±<1%. Fifty-eight (88%) articles reported on the emotional impact of patient suicide, and 50 (76%) reported on the professional impact of patient suicide. Thirty-three articles described a change in practice habits, which occurred for 51%-100% of professionals in these samples. Perceptions of support ranged widely, with 11%-87% of HCPs feeling that they received sufficient support. HCPs wanted formal support, including referral to counseling (12%-82%), more suicide prevention or postvention training (4%-70%), debriefing or supervision (41%-75%), formal case review (18%-20%), time off (12%), and legal assistance (4%).CONCLUSIONSHCPs can be affected by patient suicide, regardless of practice setting. More information is needed to better understand the implementation of postvention services after patient suicide and to create practical and universally deliverable support services to meet HCPs' needs.
