Psychological impact of the COVID-19 pandemic on healthcare workers at acute hospital settings in the South-East of Ireland: an observational cohort multicentre study

Abstract

Objective: Our study aims to understand the psychological impact of the COVID-19 pandemic among healthcare workers (HCWs) at acute hospital settings in the South-East of Ireland, as a crucial step in guiding policies and interventions to maintain their psychological well-being.

Design: Observational cohort study.

Participants and setting: 472 HCWs participated from two distinct acute hospital settings, A and B, in the South-East of Ireland.

Primary and secondary outcome measures: Measures of psychological distress-depression, anxiety, acute and post-traumatic stress disorder (PTSD)-as dictated by the Depression, Anxiety and Stress Scale (DASS-21) and Impact of Event Scale-Revised (IES-R). An independent sample t-test and a Mann-Whitney U test was used to determine significance of difference in continuous variables between groups. Categorical variables were assessed for significance with a χ² test for independence.

Results: The DASS-21 provided independent measures of depression (mean 4.57, IQR 2-7), anxiety (mean 3.87, IQR 1-6) and stress (mean 7.41, IQR 4-10). Positive scores were reflected in 201 workers (42.6%) for depression and 213 (45.1%) for both anxiety and stress. The IES-R measured subjective distress on three subscales: intrusion (mean 1.085, IQR 0.375-1.72), avoidance (mean 1.008, IQR 0.375-1.5) and hyperarousal (mean 1.084, IQR 0.5-1.667). Overall, 195 cases (41.3%) were concerning for PTSD. Site B scored significantly higher across all parameters of depression (5.24 vs 4.08, p<0.01), anxiety (4.66 vs 3.3, p<0.01), stress (8.91 vs 6.33, p<0.01) and PTSD (0.058 vs 0.043, p<0.01). Worse outcomes were also noted in HCWs with underlying medical ailments.

Conclusion: Psychological distress is prevalent among HCWs during the COVID-19 pandemic; screening for adverse mental and emotional outcomes and developing timely tailored preventative measures with effective feedback are vital to protect their psychological well-being, both in the immediate and long-term.
