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

Background: 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. Methods: 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. Results: 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. Conclusion: 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.
