[Sleep quality and mental health after bloodborne occupational exposure among medical staff in a new crown square cabin: chain mediation of social support and psychological resilience].

Objective: To investigate the relationship between sleep quality, social support, psychological resilience and mental health status of medical staff following bloodborne occupational exposure in a square pod hospital, and the mediating role of social support and psychological resilience.

Methods: A whole group sample of medical staff who had blood-borne occupational exposure in Lanzhou City Square Cabin Hospital from November to December 2022 were surveyed using self-administered general information questionnaire, Pittsburgh Sleep Quality Index(PSQI), self-reporting inventory(SCL-90) scale, social support rating scale(SSRS) and psychological resilience scale(CD-RISC), and SPSS 27.0 software and Process V 4.1 plug-in were used to analyze the quality of medical staff's sleep, psychological well-being, relationships between social support and psychological resilience were analyzed.

Results: (1) A total of 332 medical personnel who had experienced blood-borne occupational exposure were investigated in this study. Most of them were male(n=254, 76.51%), mostly aged 26-45 years(n=262, 78.92%), and the majority of them were aged 11-19 years(n=138, 41.57%). The detection rate of needle stab injury was 73.49%(n=244), and the detection rate of sharp instrument injury was 82.53%(n=274). The detection rate of sleep disorder was 60.84%(n=202) and the positive rate of SCL-90 was 50.30%(n=167). (2) The total score of sleep quality was negatively correlated with the total score of social support(r=-0.257, P<0.01), the total score of mental resilience was negatively correlated with r=-0.276, P<0.01, and the total score of symptom checklist was positively correlated with r=0.580, P<0.01. The total score of SSCS was negatively correlated with the total score of social support(r=-0.286, P<0.01) and the total score of mental resilience(r=-0.403, P<0.01). The total score of social support was positively correlated with the total score of mental resilience(r=0.406, P<0.01). (3) Sleep quality had a direct negative effect on mental health, with an effect value of 11.83%(95%CI 0.462-1.386). Psychological resilience mediated the relationship between sleep quality and mental health, with an effect value of 5.43%(95%CI 0.093-0.837). Social support and psychological resilience mediated the relationship between sleep quality and mental health. mediating role, with an effect value of 2.66%(95%CI 0.080-0.353).

Conclusion: Overall poor sleep quality and mental health among medical staff following bloodborne occupational exposure in square pod hospitals, in which social support and psychological resilience play chain-mediated roles.
