Aims and objectives To explore published literature that describes what is known about the role of informal caregivers as they manage medications for older adults and/or people living with dementia residing in the community. Background The number of informal caregivers of older adults, including people living with dementia, is growing worldwide. Good medication management by informal caregivers contributes to improved health outcomes and reduced institutionalisations for the care recipient; however, little is known about this domain of care. Design Narrative review. Methods A literature search was conducted to identify relevant research articles written in English between January 2000-April 2013, sourced from online database searches using multiple keywords, reviewing reference lists and citations of key articles and Internet searches. Articles were included if they described informal caregiver medication management for older adults and/or people living with dementia. Results Ten articles were found that described this role from the perspective of the informal caregiver. The evidence suggests that this role is complex and is often made more difficult because of increasing medication regimen complexities, aspects of the relationship between the caregiver and the care recipient, healthcare system practices and a lack of information and/or training available to the informal caregiver, especially when caring for people living with dementia. Conclusion Responsibility for managing medications for older adults and/or people living with dementia in the community often falls to informal caregivers. More information resources are required for this role, which requires specific medication management skills and knowledge and is further complicated by the cognitive decline of the care recipient.
