The feasibility and validity of a preference-weighted composite endpoint to establish value in geriatric care

Background As part of the Dutch National Care for the Elderly Programme, The Older Persons and Informal Caregivers Survey Minimum Data Set (TOPICS-MDS) was developed to gather uniform information on outcome measures. Furthermore, to combine the outcome measures into one single index and to promote comparability between studies, a preference-weighted Composite End Point (called: TOPICS-CEP) was developed [1]. The aim of this study was to validate TOPICS-CEP in a large heterogeneous sample of older persons aged ≥65 years.
