Objective

To investigate the prevalence of posttraumatic stress symptoms (PTSS) of health care workers (HCWs) who were potentially or directly exposed to patients with coronavirus disease 2019 (COVID-19) in a non-core epidemic area of China.

Methods

Psychological conditions were evaluated by the multiple psychological evaluation scales in HCWs at the Affiliated Hospital of Xuzhou Medical University in Xuzhou City (a non-core epidemic area in China) during COVID-19 epidemic. According to the risk of exposure to COVID-19 patients, HCWs were divided into two groups: HCWs with high-risk (HHCW) group (who worked in wards for COVID-19 patients) and HCWs with low-risk (LHCW) group (who worked in wards for non-COVID-19 patients in the same hospital). The clinical data of psychological evaluation scales from HCWs were collected.

Results

A total of 171 HCWs were recruited in this study, with 94 (55.0%) HCWs in the HHCW group, and 77 (45.0%) HCWs in the LHCW group. Significant differences were observed in gender, work stress, job risk, and levels of fear and anxiety, and the depression between the two groups (P < 0.05). The incidence of PTSS was 28.7% in HHCW group, while the incidence of PTSS was 13.0% in LHCW group. The PTSS between the two groups was statistically significant (P < 0.05). Further logistic regression analysis displayed that the exposure to COVID-19, work stress and coping strategies were major risk factors associated with PTSS.

Conclusions

This study demonstrated that HCWs in HHCW group had a higher chance of developing PTSS when compared with those in LHCW group. The HCWs who were exposed to COVID-19 patients had more stress and chronic stress-related disorders. Stress management should be provided to the first line HCWs who combat with COVID-19.
