The findings from the current study indicated that staff working in an ICU can experience significant stress and this was negatively associated with health and wellbeing: 32% of the sample were categorised as being at risk of psychiatric morbidity and 18% as being at risk of depression. These findings are comparable with empirical evidence that between 20 and 30% of ICU professionals are at risk of psychiatric morbidity [1, 2] and 10–25% express depressive symptoms [2, 32].
