Context
Understanding the context within which a behaviour change intervention is implemented helps explain why an intervention did or did not change behaviour (5). Contextual factors include the setting e.g. the size of a hospital and characteristics of its wards, and organisational arrangements of how staff work and interact with the intervention. Other contextual factors that may influence a deprescribing intervention include the characteristics of staff delivering or receiving the intervention such as their level of experience, views on deprescribing and other initiatives also occurring at the site e.g. other deprescribing research. An intervention may change behaviour in one setting but not another owing to contextual differences. Understanding these contextual factors is key to facilitating the intervention being adopted into the wider healthcare system after completing a definitive trial (5). This permits the implementation strategy for an intervention to be adapted according to local contextual factors.
