The sustained psychological impact of coronavirus disease 2019 pandemic on hospital workers 2 years after the outbreak: a repeated cross-sectional study in Kobe.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

COVID-19 delirium and encephalopathy: Pathophysiology assumed in the first 3 years of the ongoing pandemic.

Background: The coronavirus disease (COVID-19) continues to spread worldwide. It has a high rate of delirium, even in young patients without comorbidities. Infected patients required isolation because of the high infectivity and virulence of COVID-19. The high prevalence of delirium in COVID-19 primarily results from encephalopathy and neuroinflammation caused by acute respiratory distress syndrome (ARDS)-associated cytokine storm. Acute respiratory distress syndrome has been linked to delirium and psychotic symptoms in the subacute phase (4 to 12 weeks), termed post-acute COVID-19 syndrome (PACS), and to brain fog, cognitive dysfunction, and fatigue, termed "long COVID," which persists beyond 12 weeks. However, no review article that mentions "COVID-19 delirium" have never been reported. Basic Procedures: This narrative review summarizes data on delirium associated with acute severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and related neurological symptoms of persistent post-infection illness (PACS or long COVID) after persistence of cognitive dysfunction. Thus, we describe the pathophysiological hypothesis of COVID-19 delirium and its continuation as long COVID. This review also describes the treatment of delirium complicated by COVID-19 pneumonia. Main Findings: SARS-CoV-2 infection is associated with encephalopathy and delirium. An association between COVID-19 infection and Alzheimer's disease has been suggested, and studies are being conducted from multiple facets including genetics, cytology, and postmortem study. Principal Conclusions: This review suggests that COVID-19 has important short and long-term neuropsychiatric effects. Several hypotheses have been proposed that highlight potential neurobiological mechanisms as causal factors, including neuronal-inflammatory pathways by cytokine storm and cellular senescence, and chronic inflammation.

Characteristics of suicidal emergency room patients before and during the COVID-19 pandemic in Japan.

AIM: Owing to the stress caused by the behavioral restrictions and lifestyle changes during the COVID-19 pandemic, suicide rates have increased in Japan, especially among young people. This study aimed to identify the differences in the characteristics of patients hospitalized for suicide attempts in the emergency room, requiring inpatient care before and during the pandemic over 2 years. METHODS: This study was a retrospective analysis. Data were collected from the electronic medical records. A descriptive survey was conducted to examine changes in the pattern of suicide attempts during the COVID-19 outbreak. Two-sample independent t-tests, Chi-square tests, and Fisher's exact test were used for data analysis. RESULTS: Two hundred one patients were included. No significant differences were found in the number of patients hospitalized for suicide attempts, average age, or sex ratio before and during the pandemic periods. Acute drug intoxication and overmedication in patients increased significantly during the pandemic. The self-inflicted means of injury with high fatality rates were similar during the two periods. The rate of physical complications significantly increased during the pandemic, while the proportion of unemployed individuals significantly decreased. CONCLUSIONS: Despite studies predicting an increase in suicides based on past statistics of young people and of women, no significant changes were observed in this survey of the Hanshin-Awaji region, including Kobe. This may have been owing to the effect of suicide prevention measures and mental health measures implemented by the Japanese government after an increase in suicides and after past natural disasters.

Motivation and hesitation of healthcare workers to work during the H1N1 influenza and COVID-19 pandemics: An exploratory single-centered repeated cross-sectional study.

Aim: Pandemics of life-threatening viruses have detrimental impacts on the motivation of healthcare workers to work. However, no study has examined this impact during different pandemics with the same setting and design. This study aimed to reveal similarities and differences in factors associated with willingness and hesitation to work between two recent pandemics, H1N1 influenza and COVID-19, in the same hospital, using the same questionnaire. Methods: Healthcare workers in one hospital in Japan completed a questionnaire on basic characteristics and stress-related questions during the H1N1 influenza (n = 1061) and the COVID-19 (n = 1111) pandemics. Logistic regressions were performed to ascertain the effect of personal characteristics and stress-related questions on the likelihood that employees showed strong or weak motivation or hesitation to work. Results: The feeling of being protected by the hospital was the only factor that significantly decreased hesitation and increased motivation to work, and females felt significantly more hesitation to work than males did in both pandemics. Conclusions: Hospital managers and government officers should focus on increasing organizational support and caring for female workers to maintain healthcare workers' motivation to work during future pandemics.

Remorse-related suicide attempts among young mothers after COVID-19 infection.

Background: In Japan, there is a tendency to view COVID-19 infection as one's own responsibility, which may result in more feelings of guilt than in other countries. During the COVID-19 pandemic, the curfew imposed by COVID-19 restricted social behavior and increased anxiety and loneliness, which may have increased the risk of suicide among young women, especially mothers who were highly stressed regarding COVID-19 infection in their children. Case Presentation: This is a case report of two Japanese mothers who developed feelings of guilt following infection with COVID-19, leading to suicide attempts. They feared stigma or denial due to the infection, which they were unable to explain to others, leading to a heightened sense of self-blame and suicide attempts. In addition, Japanese women have a heavy burden of housework, despite their dual roles at home and at work; the pandemic's behavioral restrictions led to increased time at home and stress. These women were also more affected by the economic crisis in the early stages of the pandemic than men. Relatedly, neuropsychiatric symptoms that persisted after recovering from COVID-19, such as depression, anxiety, fatigue, and pain, namely postacute COVID-19 syndrome or long COVID, may have precipitated the suicidal ideation in these cases. Moreover, the complication of bipolar disorder by COVID-19 could have led to suicide attempts caused by infection-related neuropsychiatric symptoms and the exacerbation of the bipolar disorder by restrictions imposed during the pandemic. Conclusion: Suicide prevention measures need to be taken more seriously among mothers during or after the COVID-19 pandemic.

Psychological impact of the COVID-19 pandemic on hospital workers in Kobe: A cross-sectional survey.

Aim: Many health-care workers exposed to coronavirus disease 2019 (COVID-19) are psychologically distressed. This study aimed to investigate the psychological impact of the COVID-19 pandemic on hospital workers under the emergency declaration in Japan. Methods: This cross-sectional, survey-based study collected sociodemographic data and responses to 19 stress-related questions and the Impact of Event Scale-Revised (IES-R), which measures post-traumatic stress disorder (PTSD) symptoms, from all 3217 staff members at Kobe City Medical Center General Hospital from April 16, 2020 to June 8, 2020. Exploratory factor analysis was applied to the 19 stress-related questions. Multiple regression models were used to evaluate the association of personal characteristics with each score of the four factors and the IES-R. Results: We received 951 valid responses; 640 of these were by females, and 311 were by respondents aged in their 20s. Nurses accounted for the largest percentage of the job category. Women, those aged in their 30s-50s, nurses, and frontline workers had a high risk of experiencing stress. The prevalence of stress (IES-R ≥ 25) was 16.7%. The psychological impact was significantly greater for those aged in their 30s-50s and those who were not medical doctors. Conclusions: This is the first study to examine the stress of hospital workers, as measured by the IES-R, under the emergency declaration in Japan. It showed that women, those aged in their 30s-50s, nurses, and frontline workers have a high risk of experiencing stress. Health and medical institutions should pay particular attention to the physical and psychological health of these staff members.
