ABSTRACT
BACKGROUND: The mental health effects of healthcare work during the COVID-19 pandemic have been substantial, but it is not known how long they will persist. This study aimed to determine if hospital workers' burnout and psychological distress increased monotonically over 1 year, during which waves of case numbers and hospitalizations waxed and waned, or followed some other pattern. METHODS: A prospective longitudinal survey was conducted at four time-points over 1 year in a cohort of 538 hospital workers and learners, which included validated measures of burnout (emotional exhaustion scale of Maslach Burnout Inventory) and psychological distress (K6). Repeated measures ANOVA tested changes over time and differences between subjects by occupational role, age and ethnic group. The direction and magnitude of changes over time were investigated by plotting rates of high scores (using cut-offs) at each time-point compared to case rates of COVID-19 in the city in which the study took place. RESULTS: There were significant effects of occupational role (F = 11.2, p < .001) and age (F = 12.8, p < .001) on emotional exhaustion. The rate of high burnout was highest in nurses, followed by other healthcare professionals, other clinical staff, and lowest in non-clinical staff. Peak rates of high burnout occurred at the second or third measurement point for each occupational group, with lower rates at the fourth measurement point. Similarly to the results for emotional exhaustion, rates of high psychological distress peaked at the spring 2021 measurement point for most occupational groups and were higher in nurses than in other healthcare professionals. CONCLUSIONS: Neither emotional exhaustion nor psychological distress was rising monotonically. Burnout and psychological distress were consistently related to occupational role and were highest in nurses. Although emotional exhaustion improved as the case rate of COVID-19 decreased, rates of high emotional exhaustion in nurses and other healthcare professionals remained higher than was typically measured in hospital-based healthcare workers prior to the pandemic. Ongoing monitoring of healthcare workers' mental health is warranted. Organizational and individual interventions to support healthcare workers continue to be important.
ABSTRACT
OBJECTIVE: The COVID-19 pandemic is expected to have a sustained psychological impact on healthcare workers. We assessed individual characteristics related to changes in emotional exhaustion and psychological distress over time. METHODS: A survey of diverse hospital staff measured emotional exhaustion (Maslach Burnout Inventory) and psychological distress (K6) in Fall 2020 (T1) and Winter 2021 (T2). Relationships between occupational, personal, and psychological variables were assessed using repeated measures ANOVA. RESULTS: Of 539 T1 participants, 484 (89.9%) completed T2. Emotional exhaustion differed by occupational role (F = 7.3, p < .001; greatest in nurses), with increases over time in those with children (F = 8.5, p = .004) or elders (F = 4.0, p = .047). Psychological distress was inversely related to pandemic self-efficacy (F = 110.0, p < .001), with increases over time in those with children (F = 7.0, p = .008). Severe emotional exhaustion occurred in 41.1% (95%CI 36.6-45.4) at T1 and 49.8% (95%CI 45.4-54.2) at T2 (McNemar test p < .001). Psychological distress occurred in 9.7% (95%CI 7.1-12.2) at T1 and 11.6% (95%CI 8.8-14.4) at T2 (McNemar test p = .33). CONCLUSIONS: Healthcare workers' psychological burden is high and rising as the pandemic persists. Ongoing support is warranted, especially for nurses and those with children and elders at home. Modifiable protective factors, restorative sleep and self-efficacy, merit special attention.
