ABSTRACT
Being a nurse was demonstrated to be a risk factor for post-traumatic stress symptoms (PTS) and insomnia among frontline staff during COVID-19 pandemic. The unidirectional relationship between insomnia and PTS highly suggested that insomnia could mediate the increasing risk of PTS among frontline nurses. However, no study had tried to clarify this mediation effect of insomnia during COVID-19 pandemic. This study aimed to investigate prevalence of insomnia and PTS among frontline doctors and nurses and to clarify the relationship between career (doctor/nurses), insomnia and PTS. A total of 211 frontline doctors and nurses completed the investigation. Insomnia was measured using a self-drafted questionnaire and PTS was assessed using primary care post-traumatic stress disorder screen (PC-PTSD). Three logistics regression models and one mediation model were performed to explore relationships between career, insomnia and PTS. The prevalence of PTS (PC-PTSD≥2) and insomnia (with 1 item in self-drafted insomnia questionnaire≥2) was 24.17% and 36.97%, respectively. Being a nurse was a shared risk factor of insomnia (OR = 4.16, 95%CI 1.30 ~ 5.77, P = 0.023) and PTS (OR = 7.51, 95%CI 1.89 ~ 40.50, P = 0.008). Compared to doctors, nurses had significantly higher prevalence of insomnia (46.32% vs. 20%, χ2 = 13.27, P < 0.001) and PTS (30.14% vs. 13.33%, χ2 = 6.57, P = 0.011). Insomnia was a significant partial mediator (B = 0.101, P = 0.026), which explained 32.53% proportions of relationship between being a nurse and PTS. PTS and insomnia were common symptoms, which should be considered in psychological aids among frontline medical staff. Insomnia might be a possible target of PTS intervention.
