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.
