Peripheral intravenous catheter clinical care standard adherence in emergency departments: A qualitative study underpinned by the behaviour change wheel.

Aim: To explore the barriers and facilitators influencing emergency department clinicians' adherence to the Australian Peripheral Intravenous Catheter (PIVC) Clinical Care Standard, using the Behaviour Change Wheel (BCW).

Background: Suboptimal PIVC practices are frequently linked to a range of patient-important adverse outcomes. The first Australian Peripheral Intravenous Catheter Clinical Care Standard was introduced in 2021, aiming to standardize practice.
