Development steps of multimodal exercise interventions for older adults with multimorbidity: A systematic review.

ABSTRACT

Background and Aims: Multicomponent exercise interventions are recommended for older adults and for those with chronic diseases. While multiple programs have been tested, no one has yet explored how these programs were developed. This review set out to determine what development steps multicomponent exercise intervention studies that include older adults with multimorbidity have taken. Methods: Systematic review and narrative synthesis. Results: One hundred and thirty-eight studies meeting review criteria (Population adults ≥60 years with multimorbidity; Intervention exercise interventions with ≥2 components; Comparator any considered; Outcome: any considered) were retrieved. Most studies (70%) do not report intervention development actions as suggested by available guidance. Notable deviations from recommendations include limited performance of systematic review of previously published evidence, lack of engagement with theory, and few examples of design then refine. Conclusions: Exercise interventions for older adults with multimorbidity do not appear to follow best practice in terms of their developing. Disregard of development recommendations risks contributing to research redundancy and/or avoidable waste, as important steps that make sure the intervention is warranted, suitable for the population in question, and tested using optimal methods and outcome measures are overlooked.
