Background: The number and proportion of older people in the UK are increasing, as are multimorbidity (potentially reducing quality of life) and polypharmacy (increasing the risk of adverse drug events). Together, these complex factors are challenging for older people, informal carers, and health and care practitioners. Objectives: MEMORABLE (MEdication Management in Older people: Realist Approaches Based on Literature and Evaluation) aimed to understand how medication management works and propose improvements. Design: A realist approach informed three work packages, combining a realist review of secondary data with a realist evaluation of primary interview data, in a theory-driven, causal analysis. Setting: The setting was in the community. Participants: Older people, informal carers, and health and care practitioners. Interventions: Studies relating to medication management and to reviewing and reconciling medications; and realist-informed interviews. Main outcome measures: Not applicable. Data sources: MEDLINE, CINAHL (Cumulative Index of Nursing and Allied Health Literature) and EMBASE were searched (all searched from January 2009 to July 2017; searched on 1 August 2017). Supplementary articles were identified by the Research Team. Data were also obtained through interviews. Review methods: Searches of electronic databases were supplemented by citation-tracking for explanatory contributions, as well as accessing topic-relevant grey literature. Following RAMESES (Realist And Meta-narrative Evidence Syntheses: Evolving Standards) guidelines, articles were screened and iteratively analysed with interview data, to generate theory-informed (normalisation process theory) explanations. Results: Developing a framework to explain medication management as a complex intervention across five stages: identifying problem (Stage 1), starting, changing or stopping medications (Stage 3) and continuing to take medications (Stage 4), where older people, sometimes with informal carers, make individual decisions and follow routines that fit medication management into their day-to-day lives, engendering a sense of control. In getting diagnosis and/or medications (Stage 2) and reviewing/reconciling medications (Stage 5), older people and practitioners share decision-making in time-limited contacts: involving four steps – sense-making, relationships, action and reflection/monitoring (normalisation process theory); and conceptualising burden – through a detailed analysis of Stage 5, generating a theoretical framework and identifying five burden types amendable to mitigation: ambiguity, concealment, unfamiliarity, fragmentation and exclusion. Proposing interventions: risk identification – a simple way of identifying older people and informal carers who are not coping, at risk and who need appropriate help and support; and individualised information – a short, personalised record and reference point, co-produced and shared by older people, informal carers and practitioners that addresses the experience of living with multimorbidities and polypharmacy. Limitations: Few studies directly address the complexity of medication management as a process and how it works. Limitations included, having identified the overall complexity, the need to focus the analysis on reviewing/reconciling medications (Stage 5), the exclusion of non-English-language literature, the focus on non-institutionalised populations and the broad definition of older people. Conclusions: MEMORABLE explored the complexity of medication management. It highlighted the way interpersonal stages in the medication management process, notably reviewing/reconciling medications, contribute to the mitigation of burdens that are often hidden. Future work: Co-produced studies to scope and trial the two proposed interventions; studies to extend the detailed understanding of medication management, linked to burden mitigation; and a study to clarify the medication management outcomes wanted by older people, informal carers and practitioners.
