Abstract Background The increasing focus on frailty in older adults underscores the significance of a timely multidimensional assessments and early detection to avert adverse outcomes. The primary aim is to integrate digital technologies, specifically online assessment tools, for the identification of frailty and the assessment of Quality of Life (QoL) in elderly individuals. Methods A nationwide multicentric study was conducted. Seven Italian centers and regions evaluated frailty in older adults residing in the community, through a prospective observational cohort study. The chosen questionnaires, Sunfrail+ and SF-12, were implemented through an easily accessible online tool, swiftly generating final scores for each test. The cross-sectional analysis included 503 older adults. The cut off to define a person “frail” is 3 positive alerts in Sunfrail baseline items, according to the literature. Results In this sample an average of 2.31 positive alerts were generated. Significant associations were established between the number of positive warnings and SF-12 physical and mental indexes, indicated by X2=53.1 (p < 0.001) and X2=25.1 (p < 0.001), respectively. The difference between two groups (frail and not frail) in relation to QoL is statistical significantly (U di Mann Whithney p < 0.001). Mean QoL mental and physical indexes are 46.3 and 39.3 in frailty group, versus 51.7 and 46.5 in non frailty group, respectively. The correlation is conceptually consistent: as frailty increases, QoL decreases. Conclusions The frailty assessment associated with the QoL assessment provides relevant information to monitor the impact of prevention interventions at community level. The assessment of frailty leads the prevention intervention whose impact could be assessed also through QoL tools. This study underlines a meaningful association between assessment tools, substantiated by conceptual correlations. Key messages • Sunfrail and SF-12 are easily accessible online tool useful for identification of frailty and the assessment of Quality of Life (QoL) in elderly individuals. • The older population in Europe is increasing a timely assessment of frailty must be a public health priority.
