Hybrid model of care for older persons for improvement of frailty index-a community-based interventional study in an urban setting.

Background: An older person undergoes a 'disablement' process with aging. A comprehensive geriatric assessment centered around the functional status informs the healthcare provider of their frailty status, based on which tailored interventions may be designed to help prevent/reverse frailty. This study was conducted to assess the improvement in frailty index by training older persons for self-care practices using a multi-domain behavioural intervention, assisted by their caregivers.

Methods: It is a community-based interventional trial among older persons aged ≥ 60 years and their primary caregivers conducted in an urban community for a period of 15 months. A hybrid model, which exploits the advantages of every indigenous geriatric model of care, in providing a holistic care to old persons, was developed and adopted. Intervention was designed to incorporate all domains of frailty assessed, based upon self-efficacy and social interdependence theory. Frail-VIG scale and SPPB scores were used to measure the outcomes.

Results: 128 older persons and their primary caregivers were recruited. Median age was 70 and 67 years in the intervention and control group respectively, with majority being males. The median frailty index at baseline was 0.36 in both the groups, with improvement in intervention group (0.20) and worsening in control group (0.44) at end-line. From the DID analysis, a reduction of 0.19 points of frailty index was observed (even after adjustment for co-variates) in the intervention group, as compared to the control group. Also, it was observed that age and gender of the old person, their per capita income and the family support played an interactive effect in improvement of the frailty index. There was a significant difference in SPPB scores as well, between the groups [5 (1) in CG vs. 7 (2) in IG, p < 0.001].

Conclusion: Frailty could be reversed with appropriate interventions designed on the pillars of self-efficacy, and social interdependence among family members. The hybrid model of care delineates the role of caregivers, who reinforce the old persons to follow prescribed interventions.
