Abstract
The Integrated Care for Older People (ICOPE) program is a healthcare pathway that uses a screening test for intrinsic capacity (IC) as its entry point. However, real-life data informing on how IC domains cluster and change over time, as well as their clinical utility, are lacking. Using primary healthcare screening data from more than 20,000 French adults 60 years of age or older, this study identified four clusters of IC impairment: ‘Low impairment’ (most prevalent), ‘Cognition+Locomotion+Hearing+Vision’, ‘All IC impaired’ and ‘Psychology+Vitality+Vision’. Compared to individuals with ‘Low impairment’, those in the other clusters had higher likelihood of having frailty and limitations in both activities of daily living (ADL) and instrumental activities of daily living (IADL), with the strongest associations being observed for ‘All IC impaired’. This study found that ICOPE screening might be a useful tool for patient risk stratification in clinical practice, with a higher number of IC domains impaired at screening indicating a higher probability of functional decline.

Data availability
The data reported in this paper (text, tables, figures and the supplementary material) will be shared in de-identified form owing to privacy protections. Requests for de-identified data and a data dictionary will be evaluated by the ICOPE-Care data-sharing committee, which can be contacted at the following address: tavassoli.n@chu-toulouse.fr. Data will be made available for investigators upon request for a pre-identified scientific purpose developed in a research proposal with sound methodology, subject to the approval of the appropriate ICOPE-Care committee; a data use agreement must also be signed. Given the nature of the ICOPE-Care program (ongoing, real-life data from healthcare services), the authors are unable to make the dataset publicly accessible at this time. In addition, according to the ICOPE-Care policy, all analyses using ICOPE-Care data (including the present study) must be evaluated and approved by the committee after submission of a comprehensive analysis proposal. Therefore, for researchers interested in accessing the data used for the current study, the same evaluation procedure must be followed.
Code availability
The codes supporting the findings of this study are available upon reasonable request from the corresponding author. All analyses were performed using programming languages in the Stata software package.
