+AGIL Barcelona: Integrated Care for Community-Dwelling Frail Older Adults

The goal of this clinical trial is to evaluate the effectiveness of the +AGIL Barcelona program in helping older adults improve their physical abilities and delay disability. It will also explore how to adapt and expand the program to different neighborhoods in Barcelona. The main questions it aims to answer are:

Does the +AGIL program improve physical abilities, as measured by a simple physical performance test (SPPB)? How well can the program be adapted and implemented in different community health centers? Researchers will conduct the study in three community health centers in Barcelona, following a stepped approach to gradually introduce the program at each site.

Participants will:

Participate in up to 10 weekly group exercise sessions led by a physiotherapist. Focus on strength, balance, flexibility, and endurance. Exercises will be tailored to individual needs and supported with easy-to-understand materials.

Receive advice on healthy habits like eating a Mediterranean diet, improving sleep, and managing swallowing or memory issues.

Get support to connect with local activities and resources to reduce loneliness and stay active, such as community centers or fitness programs.

Have their medications reviewed by healthcare professionals to ensure they are appropriate and safe.

The program will be personalized based on each participant's needs. This study will provide valuable information on implementing practical programs that help older adults stay healthy and independent.

Population aging requires the implementation of sustained integrated strategies and programs to improve intrinsic capacity and delay disability in older adults. The +AGIL Barcelona program exemplifies a pragmatic, multicomponent intervention that effectively improves physical function by integrating health and community resources. This study aims to co-design, adapt, and scale up +AGIL to diverse socioeconomic areas in Barcelona, assessing its effectiveness and evaluating the process of progressive implementation.

Methods: Multicenter, pragmatic, Stepped-Wedge Cluster Randomized Trial, performed in three Primary Care Centers in Barcelona (PCCs), involving older adults screened as frail by the Gérontopôle Frailty Screening Tool (total sample size=396, 198 per arm). After a co-design phase to adapt the protocol to each local context, the intervention will be introduced sequentially at each site, according to a randomly determined schedule, until all PCCs are exposed. The intervention, previously piloted in a different PCC, is based on a Comprehensive Geriatric Assessment followed by a 10-week tailored boost multicomponent intervention aligned with the Integrated Care for Older People (ICOPE) framework of the World Health Organization - WHO - (physical exercise being the core element). After three months, continuity of activation is pursued through the integration of community resources (public or private gyms, civic centers etc). The primary outcome will be. The investigators designed a mixed-methods evaluation, measuring physical performance improvement using the Short Physical Performance Battery (SPPB) as the primary quantitative outcome, plus a qualitative assessment of participants' experience and program implementation.

Discussion: This study will provide relevant information on the implementation and impact of pragmatic, real-life interventions to improve intrinsic capacity and prevent disability in older adults.
