Behaviour
Older adults and informal caregivers expect healthcare professionals to deprescribe medicines that are no longer appropriate (4). This requires behaviour change from healthcare professionals. Deprescribing is a complex and heterogenous process and the ‘target behaviour’, which is the thing we are asking healthcare professionals to do, varies depending on several factors. For example, asking healthcare professionals to ‘reactively’ deprescribe medicines that have already caused harm is a different behaviour to asking them to ‘proactively’ deprescribe medicines that may cause harm in the future. The first step in changing behaviour is to define the target behaviour .
