A longitudinal study of hospital workers’ mental health from fall 2020 to the end of the COVID-19 pandemic in 2023

Abstract

Abstract Most longitudinal studies of healthcare workers’ mental health during COVID-19 end in 2021. We examined trends in hospital workers eight times, ending in 2023. A cohort of healthcare workers at one organization was surveyed at 3-month intervals until Spring 2022 and re-surveyed in Spring 2023 using validated measures of common mental health problems. Of 538 workers in the original cohort, 289 (54%) completed the eighth survey. Repeated-measures ANOVA revealed significant changes in psychological distress (F = 7.4, P < .001), posttraumatic symptoms (F = 14.1, P < .001), and three dimensions of burnout: emotional exhaustion (F = 5.7, P < .001), depersonalization (F = 2.7, P = .01), and personal accomplishment (F = 2.8, P = .008). Over time, psychological distress and depersonalization increased, posttraumatic symptoms and personal accomplishment decreased, and emotional exhaustion fluctuated significantly without net change. Most measures did not improve significantly in the year prior to the declaration of the pandemic’s end. The lack of improvement in psychological distress, emotional exhaustion, depersonalization, and personal accomplishment during the period in which COVID-19 case rates declined and public health measures were relaxed is a concerning indication of the chronicity of the impact of the pandemic on healthcare workers.
