Various models of pharmaceutical services have been provided by pharmacists to old aged home residents, however, these models have never been summarised and compared. The aim of this scoping exercise is to identify different kinds of pharmaceutical services currently available to the old aged home residents, by means of systemic literature review, qualitative in-depth interviews with service providers in order to understand their models and qualitative semi-structured interviews with non-pharmaceutical service users in an attempt to investigate reasons why some homes do not subscribe to these services. The results showed that none of the pharmaceutical services currently available can uproot the causes of medication errors, and there is a need to elaborate the roles of pharmacists in a primary care setting.link_to_subscribed_fulltex
