Background An outbreak of novel coronavirus disease 2019 (COVID-19) is a newly discovered contagious disease, which first broke out in China.Based on the psychological state, maintenance hemodialysis (MHD) patients might bear psychological problemsunder the COVID-19epidemic situation.To evaluate the psychological health of MHDpatients and explore the corresponding intervention strategies.Methods Acluster sampling approach was employed to obtain a sample of 206 MHD patients from two hospitals in Yunnan province: a COVID-19-designated hospital and a non-COVID-19-designated hospital. Post-traumatic stress disorder (PTSD) checklistwas used to assess the psychological status,while Kidney Diseaseand Quality of Life --Short Form(KDQOL-SF)was applied to assess the quality of life(QOL). The factorsinfluencing thepsychological status in MHD patients were employed by binary logistic regression.Results Among MHD participants (age 53.4 ± 15.3 years), 61 cases showed mild to moderate positive PTSD, and 72 casespresented severe positive PTSD.The level of education, capital income, hospital, depressive tendency, and QOL were the influence factors for the occurrence of PTSD. Moreover, the PTSD was negatively correlated with QOL and positively correlated with COVID-19-designated hospital and the depressive tendency.Conclusion During the COVID-19 epidemic, MHD patients, especially in COVID-19-designated hospitals, with low QOL and depressive tendency had a high incidence of positive PTSD, which requires prompt psychological counseling and effective measures from medical staff to ensure timely treatment of patients.
