Digital Interventions for Frailty and Pelvic Floor Dysfunction in Older Adults: A Systematic Review Protocol

Evidence on digital interventions for frailty and pelvic floor dysfunction (PFD) is methodologically fragmented because studies usually enroll one condition rather than older adults with both diagnoses. This article presents a systematic review protocol and evidence-mapping framework for two prespecified, condition-specific evidence streams. PubMed/MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, CINAHL, CNKI, and Wanfang were searched from inception to January 31, 2026. Randomized trials were separated from nonrandomized evidence, and frailty and PFD outcomes were not combined in a single effect estimate. Source verification did not identify a study that required concurrent diagnoses of frailty and PFD, and did not establish a connected study-level network for quantitative synthesis. Published condition-specific reviews suggest that digital interventions may improve selected outcomes in PFD or frailty populations, but certainty varies, and those findings cannot be extrapolated to a dual-condition population. Accordingly, representative results are presented as a condition-specific evidence map and synthesis-decision framework; no pooled dual-condition effect, network estimate, or treatment ranking is reported. The protocol emphasizes traceable study identification, population alignment, outcome compatibility, and a prespecified gate for pairwise or network meta-analysis.
