Management of bio-psycho-social frailty to reduce hospital use and improve survival of older adults

Background Ageing of population is associated to the increase of care demand. Many health systems are still centered on hospital care, that sometime is not appropriate. The shift from hospital to community care requires a new model of service delivery. Aim of this paper is to assess the impact of a community service based on the assessment of frailty, on mortality and use of hospital care by older adults. Methods A cohort made up by 8,592 over-75 subjects (67.1% female, mean age 84.5; SD ± 5.29) has been assessed once a year for bio-psycho-social frailty by the administration of the Short Functional Geriatric Evaluation questionnaire. The enrolled subjects were involved in a Community-based pro-Active Monitoring Program which provides interventions aimed at reducing social isolation. Mortality, use of hospital care and use of residential long-term care have been recorded during the follow up and separate and cumulative incidence rate was measured. Results The sample was stratified in Robust (37.5%), Pre-frail (24.0%), Frail, (29.5%) and Very Frail (9.1%) individuals. Mortality, Hospital admission rate and Residential LTC admission rate were higher in the very frails than among the other groups. However, according to social isolation, the integrated subjects at the baseline assessment, showed the highest incidence of negative events: 29.5%, 20.8%, 21.0%, .and 20.8% for integrated, mild isolated, moderate isolated and severely isolated individuals respectively (p < 0.001). The logistic regression analysis, adjusted for age, gender and level of frailty, confirmed the protective role of reducing social isolation among isolated individuals compared with integrated ones (OR: 0.729; CL95% 0.673-0.720). Conclusions The assessment of bio-psycho-social frailty could be the starting point for effective intervention at community level, like the program mentioned above. Management of frailty may lead to an improvement of public health outcomes
