Abstract
BACKGROUND: Care of critically ill patients is complex, requiring effective collaboration co-ordination and communication across care teams and professions. Medicines are a fundamental component of the acute interventions intensive care unit (ICU) patients receive, requiring frequent review and optimisation according to patient needs. ICU patients recovering to transfer to a hospital ward are at risk of medication transition errors, contributing to poorer patient and health-system outcomes. We aimed to develop of a theory-informed intervention package to improve medication safety for ICU patients transferring to a hospital ward. METHODS: We conducted a qualitative study comprising two UK face-to-face focus group meetings in April and May 2022. There were ten participants in each meeting (7-8 healthcare professionals and 2-3 patient and public representatives). Each meeting had four foci: (i) What needs to change (intervention targets)? (ii) What are the core intervention components? (iii) What will the intervention components change and how (mechanisms of action), and what key outcomes will the changes impact on? (iv) What are the barriers and facilitators to intervention delivery? A background to the problem and previous intervention development work was provided. Meetings were digitally recorded and transcribed verbatim. Iterative analyses, informed by the Behaviour Change Wheel framework, were conducted to provide a behavioural diagnosis, identify key behaviour change techniques and outline the mechanisms of action through which the intervention might impact on key outcome. RESULTS: We identified what needs to change to improve medication safety for UK ICU patients on this care transition. A theory-informed intervention package was developed, based on seven core intervention components (e.g., medication review (targeted), task organisation and prioritisation). For each intervention component the mechanism of action, targeted change, and key outcomes were identified (e.g., medication review (targeted); action planning; decreases problematic polypharmacy; decreased preventable adverse drug events). Barriers and facilitators to intervention component delivery were described. CONCLUSIONS: We developed a theory-informed core intervention package to address the limitations in medication safety for ICU patients transferring to a hospital ward. Understanding what needs to change, and the accompanying facilitators provides a basis for intervention feasibility testing and refinement prior to future evaluation of effectiveness.
