Mental health of nurses involved with COVID-19 patients in Japan, intention to resign, and influencing factors

The purpose of this study was to investigate the association between mental health (posttraumatic stress disorder, depression, anxiety disorder, and burnout) and intention to resign, and influencing factors regarding nurses involved with COVID-19 patients in A Prefecture as subjects. The design is a cross-sectional questionnaire-based study. Methods are conducted between August 4 and October 26, 2020. Basic attributes (gender, age, years of experience, etc.) were examined. Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7, Impact of Event Scale-Revised, Maslach Burnout Inventory, “intent to resign,” were used to collect data from nurses working at hospitals treating patients with COVID-19 in Japan. As a result, between 20% and 30% of nurses involved with patients with COVID-19 are in a state of high mental distress. Regarding the associations between psychiatric symptoms and intention to resign, “I want to quit being a nurse” was affected by “cynicism” and “professional efficacy”; “I want to change hospitals/wards” was affected by “cynicism”; and “subthreshold depression,” “anxiety disorder,” and “burnout” affected “I want to continue working as a nurse.” The increase in the number of patients with COVID-19 was a factor affecting mental health and intention to resign. When the number of patients increased, anxiety disorders and intention to resign also increased. Damage from harmful rumors increased the severity of every psychiatric symptom. To prepare for a pandemic such as COVID-19, it is necessary in normal times to construct psychological support systems and community systems to prevent damage from harmful rumors.
