The rate and impact of substance misuse in psychiatric intensive care units (PICUs) in the UK

Abstract

Purpose This paper aims to understand the current scale of substance misuse in psychiatric intensive care units (PICUs), identify how substance misuse affects members of staff, patients and the running of wards and explore with staff what resources would be most useful to more effectively manage substance misuse and dual diagnosis on PICUs. Design/methodology/approach The paper used a mixed-methods approach, using a quantitative survey to determine the extent of substance use in PICUs and a co-design workshop to understand the impact of substance misuse on PICU wards, staff and patients. Findings The estimated rate of substance misuse in PICUs over a 12-month period is 67%, with cannabis the most frequently used substance. Despite the range of problems experienced on PICUs because of substance misuse, the availability of training and resources for staff was mixed. Research limitations/implications The findings may not be fully generalisable as research participants were members of a national quality improvement programme, and therefore, may not be representative of all PICUs. Data was collected from clinicians only; if patients were included, they might have provided another perspective on substance misuse on PICUs. Practical implications This paper emphasises the importance of substance misuse training for PICU staff to adequately respond to patients who misuse substances, improve the ward environment, staff well-being and patient outcomes. Originality/value This paper provides an updated estimation of rates of substance misuse in PICUs over a 12-month period and make suggestions for a training programme that can better support staff to address substance misuse on PICUs.
