The use of behaviour change theory for infection prevention and control practices in healthcare settings: A scoping review.

Background: Infection prevention and control (IPC) practices performed by healthcare workers are key to the prevention and management of infections. Compliance with IPC practices is often low, they are therefore commonly the focus of improvement interventions. Designing interventions that are based on behaviour change theories may help to improve compliance to practice. The aim of this review is to synthesise the evidence on the application of behaviour change theories to interventions to improve IPC practice in healthcare settings.

Methods: A scoping review was conducted following the Joanna Briggs Institute methodological framework. The theories of focus were the Theoretical Domains Framework (TDF), Capability, Opportunity, Motivation, Behaviour (COM-B) and Behaviour Change Wheel (BCW). Studies which applied these theories to any IPC practice were included.

Results: Eleven studies were identified which met the inclusion criteria. The IPC behaviours investigated were hand hygiene (7), antimicrobial stewardship (3), and MRSA screening (1). Nine studies explored barriers and facilitators to existing IPC practice; three used their findings to design a behaviour change intervention or tool. Domains of 'beliefs about consequences', 'environmental context/resources', and 'social/professional role and identity' were identified as key across all three IPC behaviours.

Discussion: This review has demonstrated the use of behavioural theories to understand determinants of behaviour related to IPC practice. Currently, there are few published examples of interventions to improve IPC practice that have been underpinned by behavioural theory. Practitioners in IPC should consider the use of these methods to enhance the efficacy of strategies to change healthcare worker behaviour.
