Abstract: Objective To systematically evaluate a cross-sectional study on the influencing factors of clinical nurses' second victims using the second victim experience and support scale as a tool,and provide reference for the development of relevant intervention measures for clinical nurses' second victims. Methods The databases of CNKI,Wanfang,VIP,CBM,Pubmed,WOS,Embase,and Cochrane Library were searched by computer,and the study on the influencing factors of the experience and support of the second victim of clinical nurses was collected. The retrieval time was from the establishment of the database to October 2023. Meta-analysis was conducted using Revman 5.3 software. Results A total of 19 studies were included,including 13 999 clinical nurses. Personal related factors included the degree of desire to resign（r=0.159,95%CI：0.100-0.264）,perceived internal organizational pressure（r=0.149,95%CI：0.090-0.197）,with the working years（r=0.110,95%CI：0.030-0.178）,clinical department（r=0.110, 95%CI：0.040-0.178）,professional title（r=0.139,95%CI：0.020-0.245）,the number of adverse events（r=0.110,95%CI：0.050-0.168） and monthly night shift（r=0.149,95%CI：0.050-0.245） in background/environmental factors,which were weakly positively correlated with the experience and support of the second victim of clinical nurses（all P<0.05）. Resourcefulness level（r=-0.446, 95%CI：-0.585--0.282） and resilience（r=-0.438,95%CI：-0.551--0.310） were moderately negatively correlated with the experience and support of the second victim of clinical nurses（both P<0.05）. Sense of organizational support（r=-0.565,95%CI：-0.824--0.119） among background/environmental factors was highly negatively correlated with the experience and support of the second victim of clinical nurses（P<0.05）. Conclusion The level of resourcefulness,psychological resilience,sense of organizational support,working years,professional title,clinical department,number of night shifts per month,degree of desire to resign,number of adverse events,and perceived internal organizational pressure were the main influencing factors for the experience and support of the second victim of clinical nurses. Hospital nursing administrators should establish appropriate care programs and support systems,and conduct peer and leader training related to support.
