Healthcare workers who are exposed to coronavirus disease 2019 are psychologically distressed. This study aimed to evaluate the mental health outcomes of hospital workers 2 years after the outbreak of coronavirus disease 2019 and to identify changes in the stress of hospital workers and predicted risk factors. This survey was conducted 2 years after the initial evaluation performed under the first emergency declaration of the coronavirus disease 2019 pandemic among hospital workers at the same hospital in an ordinance-designated city in Japan from June to July 2022. Sociodemographic data, 19 stress-related question responses, the Impact of Event Scale-Revised, and the Maslach burnout inventory-general survey were collected. Multiple regression models were used to identify factors associated with each of the mental health outcomes 2 years after the coronavirus disease 2019 outbreak. We received 719 valid responses. Between 2020 and 2022, hospital workers' anxiety about infection decreased, whereas their exhaustion and workload increased. Multiple regression analysis revealed that 2 years after the coronavirus disease 2019 outbreak, nurses and young people were at a higher risk of experiencing stress and burnout due to emotional exhaustion, respectively. This is the first study to examine the long-term stress of hospital workers measured in Japan. Exhaustion and workload were worsened 2 years into the pandemic. Therefore, health and medical institutions should continuously monitor the physical and psychological health of staff members.
