'Just keep taking them, keep hoping they'll work': A qualitative study of adhering to medications for multimorbidity.

We identified factors relevant to medication adherence for older adults with multimorbidity that go beyond single-disease influences and account for the amplified experience of chronic disease that multimorbidity can produce for some people. While evidence of single-disease influences remains fundamental to tailoring behavioural interventions to individuals, the impact of multimorbidity on medication adherence should be accounted for in research and practice.
