Assessing the psychological impact of COVID-19 on intensive care workers: A single-centre cross-sectional UK-based study.

Abstract

COVID-19 has presented a unique set of psychological stressors for healthcare professionals. There is currently a dearth of literature establishing the impact amongst intensive care workers, who may be at the greatest risk. This study aimed to establish the prevalence of anxiety, depression and post-traumatic stress disorder amongst a cohort of intensive care workers within the United Kingdom. A questionnaire was designed to incorporate validated screening tools for depression (Patient Health Questionnaire, PHQ-9) anxiety (Generalised Anxiety Disorder Scale, GAD-7), and post-traumatic stress disorder (Impact of Event Scale-Revised, IES-R). All intensive care workers at the Countess of Chester Hospital (UK) were eligible. Data was collected between 17th June and 8th July 2020. The majority of the 131 respondents were nurses (52.7% [69/131]) or doctors (32.8% [43/141]). Almost one-third (29.8% [39/131]) reported a significant or extreme impact of COVID-19 on their mental health. In total, 16%(21/131) had symptoms of moderate depression, 11.5%(15/131) moderately severe depression and 6.1%(8/131) severe depression. Females had significantly higher mean PHQ-9 scores than males (8.8 and 5.7 respectively, p = 0.009). Furthermore, 18.3% (24/131) had moderate anxiety with 14.5% (19/131) having severe anxiety. Mean GAD-7 scores were higher amongst females than males (8.7 and 6.3 respectively, p = 0.028). Additionally, 28.2% (37/131) reported symptoms consistent with a diagnosis of PTSD (IES-R ≥ 33). Despite these findings, only 3.1% (4/131) of staff accessed trust mental health support. The impact of COVID-19 on intensive care workers is significant and warrants specific focus and attention in order to preserve this key sector of the workforce.
