Medication management in older people: the MEMORABLE realist synthesis

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
