Two-year follow-up of post-traumatic stress disorder symptoms in healthcare workers after the COVID-19 pandemic in China

Objectives: This study aimed to conduct a 2-year follow-up of mental disorders in healthcare workers (HCWs) in a region of China outside the epidemic’s core zone who happened to be directly or possibly exposed to persons with COVID-19. Material and Methods: A cognitive analysis scale was utilized in the evaluation the mental or emotional state of HCWs at Xuzhou Medical University’s affiliated hospital in the city of Xuzhou, China (a non-core epidemic area) 2 years after the first assessment during the COVID-19 pandemic. A total of 165 HCWs were selected as the study subjects. In accordance to the exposure risk of COVID-19 patients, the subjects were separated into 2 categories: a group with a high risk HCW (HHCW) (HCWs working in COVID-19-positive wards; N = 91) and a group with a minimal risk HCW (LHCW) (HCWs who worked in wards without COVID-19 patients at the same hospital; N = 75). The clinical as well as demographic information of every HCWs were collected. Results: The demographic data revealed significant differences in terms of occupation, remuneration, and selfless concerns amidst both categories (p < 0.05). There lacked a statistically notable difference in the occurrence of PTSD between the 2 groups. Data was analyzed for factors associated with PTSD, and the results showed that psychological resilience, job risk, and stress in the workplace were risk factors for PTSD. Additionally, the results of the logistic regression analysis showed that psychological resilience was a significant shared risk factor for PTSD in HCWs after the COVID-19 pandemic. Conclusions: The 2-year follow-up showed no statistical difference in the incidence of PTSD between the HHCW group and the LHCW group. Workplace stress, occupational hazards, and psychological resilience were the major contributing risk factors for PTSD in HCWs.
