Background: For most people, the last 12 months of life are spent living in the community, with the support of family and friends for a number of caregiving functions. Previous research has found that managing medicines is challenging for caregivers. Currently there is little information describing which caregivers may struggle with tasks associated with managing a loved one's medicines. Aim: The aim of this study was to identify factors that flag caregivers who are likely to experience problems when managing someone else's medications.
