COVID-19 and post-traumatic stress disorder among nurses: a descriptive cross-sectional study in a COVID hospital.

Background In March 2020, the World Health Organisation (WHO) declared the novel coronavirus (COVID-19) outbreak a global pandemic. Healthcare professionals directly involved in diagnosing, treating and caring for patients with COVID-19 are at risk of developing post-traumatic stress disorder (PTSD). Objective This study investigated the prevalence of PTSD among nurses working in a COVID hospital and evaluated associated factors. Methods A descriptive cross-sectional study was conducted at Crema Hospital and the Impact of Event Scale - Revised (IES-R) was administered. Data collection took place from July to September 2020, during which 275 questionnaires were distributed. Results Of the total sample, 39.88% received a provisional PTSD diagnosis deserving of further analysis. Nurses stated that they were predominantly overwhelmed by intrusive thoughts (M = 1.55). Working in the emergency department during the COVID-19 pandemic (OR=2.40; p=0.02), irregular work shifts (OR=5.41; p=0.01) and coming from a mental health ward (OR=3.80; p=0.02) increased the risk of receiving a provisional PTSD diagnosis. Our findings showed significantly higher IES-R scores among women than among men (p = 0.01). The activities that caused the most distress were related to technical skills required for managing ventilation and intubation devices. Conclusions The results of the study highlighted the presence of considerable psychological distress in the sample. There is an urgent need to monitor the short- and long-term consequences of the COVID-19 pandemic and implement early intervention measures.
