A modified Delphi and cross-sectional survey to facilitate selection of optimal outcomes and measures for a systematic review on geriatrician-led care models

OBJECTIVE: The objective of this study was to identify relevant outcomes and measures to inform a systematic review (SR) on the comparative effectiveness of geriatrician-led care models. STUDY DESIGN AND SETTING: In the modified Delphi to select outcomes for inclusion in the SR, knowledge users (KUs) from Ontario, Alberta, and Saskatchewan rated outcome importance using a Likert scale. A survey was then completed by geriatricians to determine optimal measures for selected outcomes. Findings were analyzed using frequencies, means, and standard deviations (SDs). RESULTS: Thirty-three KUs (patients, caregivers, policymakers and geriatricians) rated 27 outcomes in round 1 of the modified Delphi. Top-rated outcomes included function (mean 6.85 ± SD 0.36), cognition (6.47 ± SD 0.72), and quality of life (6.38 ± SD 0.91). Twenty-three KUs participated in round 2 and rated 24 outcomes. Top-rated outcomes in round 2 were function (6.87 ± SD 0.34), quality of life (6.45 ± SD 1.10), and cognition (6.43 ± SD 0.73). The survey was completed by 22 geriatricians and the highest ranked measures were Activities of Daily Living (function), Mini-Mental State Examination (cognition), and the Medical Outcomes Study SF-36 (quality of life). CONCLUSION: We identified the most relevant outcomes and measures for patients, caregivers, policymakers, and geriatricians, allowing us to tailor the SR to KU needs.
