Although muscle mass, muscle strength, or functional performance typically serve as the primary endpoints, regulatory agencies have recently emphasized integrating Patient-Reported Outcome Measures (PROMs) as primary or secondary outcomes in interventional studies. This shift acknowledges the importance of PROMs and Patient-Reported Experience Measures (PREMs) in assessing intervention effectiveness and aligns with patient-centered healthcare models. The aims of this systematic review are 1) to identify all sarcopenia-designed interventional studies that used PROMs/PREMs as the primary or secondary outcome, 2) to identify the different PROMs/PREMs used within those studies, and 3) to summarize the effects of sarcopenia-designed interventions on PROMs/PREMs of sarcopenic participants. For that, a systematic search of databases (Medline, EMBASE, Review- Cochrane Central of Register of Controlled Trials, and PsychINFO (Via Ovid)) was conducted in September 2023. The review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement, and the protocol was registered on Open Science Framework (https://osf.io/zxgwm/). The systematic review identified 17 RCTs as sarcopenia-designed interventional studies reporting PROMs. PROMs covered the assessment of various aspects, including quality of life, depressive symptoms, loneliness/social isolation, daytime sleepiness, insomnia impact, and sleep quality/disturbance. Only one sarcopenia-specific PROM, namely the SarQoL, was reported. The effect of sarcopenia-designed interventions on PROMs showed considerable heterogeneity, underscoring the need for standardization in sarcopenia research by developing a Core Outcome Set (COS). COS in sarcopenia studies would ensure consistent and comparable findings, ultimately enhancing the reliability and effectiveness of interventions.</p>","PeriodicalId":51629,"journal":{"name":"Journal of Frailty & Aging","volume":"13 3","pages":"224-232"},"PeriodicalIF":3.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141857073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
