Predictive Capacity of the Integrated Care for Older People Screening Tool for Intrinsic Capacity Impairments: Results From the INSPIRE-T Cohort

Abstract

Background The Integrated Care for Older People (ICOPE) approach was developed by the World Health Organization (WHO) aiming to shift the traditional focus of care based on diseases to a function- and person-centered approach, focused on maintaining and monitoring intrinsic capacity (IC). This study aimed to investigate the ability of the ICOPE screening tool to identify older people with clinically meaningful impairments in IC domains. Methods This cross-sectional analysis included 603 older adults, participants (mean age 74.7 [SD 8.8] years, women 59.0%) of the INSPIRE Translational (INSPIRE-T) cohort. Responses at screening were compared to results of the subsequent in-depth assessment (i.e., Mini Mental State Examination, Mini Nutritional Assessment, Short Physical Performance Battery, Patient Health Questionnaire-9, and clinical investigation of vision problems) to determine its predictive capacity for impairments at the IC domains (i.e., cognition, psychological, sensory (vision), vitality, and locomotion). Results The ICOPE screening items provided very high sensitivity for identifying abnormality in vision (97.2%), and varied from 42.0% to 69.6% for the other domains. High specificity (>70%) was observed for all the IC domains, except for vision (2.7%). Conclusions The ICOPE screening tool can be a useful instrument enabling the identification of older people with impairments in IC domains, but studies with different populations are needed. It should be considered as a low-cost and simple screening tool in clinical care.
