Recommendations of outcome measurement instruments used for the evaluation of community-based complex interventions targeted at sustaining the independence in older people with frailty
There is growing evidence from randomised controlled trials that older people participating in complex interventions may have improved outcomes. However, synthesis of trial evidence in meta-analysis can be hampered by variability in outcome measurement instruments (OMIs) across trials. This project includes identifying and narrowing down which OMIs are the most appropriate to use within specific domains. Several methods will be utilised to facilitate this process including using existing research to identify the OMIs currently used to evaluate complex interventions in older people with frailty using a systematic methodological overview. The systematic methodology overview will be utilised to create a recommended set of OMIs evaluating complex interventions targeted at sustaining the independence in older people with frailty. A step-by-step quality assessment will be conducted using a guideline to narrow down the OMIs selected to evaluate complex interventions in older people. This quality assessment will be used to explore varying measurement properties and feasibility aspects. A nominal group discussion will be utilised to aid in generating recommendations of OMIs in randomised controlled trials of older people with frailty.
