Impact on physical function of the +AGIL Barcelona program in community-dwelling older adults with cognitive impairment: an interventional cohort study.

BACKGROUND: Older adults with cognitive impairment (CI) have higher multimorbidity and frailty prevalence, lower functional status and an increased likelihood to develop dementia, non-cognitive deficits, and adverse health-related events. +AGIL, a real-world program for frail older adults in a primary care area of Barcelona, is a pragmatic, multi-component and integrated intervention implemented since 2016. It includes physical activity, nutrition, sleep hygiene, revision and adequacy of pharmacological treatment, detection of undesired loneliness and screening for CI; to improve physical function in community-dwelling older adults. We aimed to assess the + AGIL longitudinal impact on physical function among community-dwelling frail older persons with CI. METHODS: An interventional cohort study included data from all the + AGIL consecutive participants from July 2016 until March 2020. Based on the comprehensive geriatric assessment, participants were offered a tailored multi-component community intervention, including a 10-week physical activity program led by an expert physical therapist. Physical performance was measured at baseline, three and six months follow-up. The pre-post impact on physical function was assessed by paired sample t-test for repeated samples. Linear mixed models were applied to analyze the + AGIL longitudinal impact. P-values < 0.05 were considered statistically significant. RESULTS: 194 participants were included (82 with CI, based on previous diagnosis or the Mini-COG screening tool), 68% women, mean age 81.6 (SD = 5.8) yo. Participants were mostly independent in Activities of Daily Living (mean Barthel = 92.4, SD = 11.1). The physical activity program showed high adherence (87.6% attended ≥ 75% sessions). At three months, there was a clinically and statistically significant improvement in the Short Physical Performance Battery (SPPB) and its subcomponents in the whole sample and after stratification for CI [CI group improvements: SPPB = 1.1 (SD = 1.8) points, gait speed (GS) = 0.05 (SD = 0.13) m/s, Chair stand test (CST)=-2.6 (SD = 11.4) s. Non-CI group improvements: SPPB = 1.6 (SD = 1.8) points, GS = 0.08 (SD = 0.13) m/s, CST=-6.4 (SD = 12.1) seg]. SPPB and gait speed remained stable at six months in the study sample and subgroups. CI had no significant impact on SPPB or GS improvements. CONCLUSION: Our results suggest that older adults with CI can benefit from a multidisciplinary integrated and comprehensive geriatric intervention to improve physical function, a component of frailty.

Integrated primary and geriatric care for frail older adults in the community: Implementation of a complex intervention into real life.

BACKGROUND: Frailty is highly prevalent in older persons and associated with negative health-related events and costs. Despite successful clinical trials, translation of evidence into implementation of dedicated programs has been scarce. This is probably due to funding limitations and lack of generalizability of rigid schemes adopted in controlled studies. We propose a guidance to implement complex interventions against frailty in the community, and describe the design and early findings of the +AGIL Barcelona program. METHODS: A guidance "decalogue" resulted from an experts' panel prioritization of recommendations by international independent bodies. On this basis, we reorganized existing primary care, geriatrics and community-based resources to implement our program, which includes a screening, a multi-component intervention modulated on the comprehensive geriatric assessment and integrated follow-up plus continuity through community-based resources. The pre-post impact of the program on physical function, as well as on clinical endpoints, person-center outcomes and costs will be assessed. RESULTS: Integrated care, multi-component, person-centered strategies to empower the final users in a flexible and adaptable way should be promoted after raising awareness and potentially convey long term investments. In 22 months, 185 participants (mean age ±â€¯SD = 81.6 ±â€¯5.7 years, 72% women) joined the program. Although independent in the activities of daily living, participants showed clear indicators of frailty (Short Physical Performance Battery = 7.1 ±â€¯2.5; gait speed = 0.69 ±â€¯0.2 m/s). CONCLUSIONS: +AGIL Barcelona may represent a unique model to manage frailty in older community-dwellers, translating evidence into pragmatic clinical practice. Further research will clarify the effects of this intervention.
