Background: One of the most problematic expression of ageing is frailty, and an approach based on its early identification is mandatory. The Sunfrail-tool (ST), a 9-item questionnaire, is a promising instrument for screening frailty.
Aims: To assess the diagnostic accuracy and the construct validity between the ST and a Comprehensive Geriatric Assessment (CGA), composed by six tests representative of the bio-psycho-social model of frailty; To verify the discriminating power of five key-questions of the ST; To investigate the role of the ST in a clinical-pathway of falls' prevention.
Methods: In this retrospective study, we enrolled 235 patients from the Frailty-Multimorbidity Lab of the University-Hospital of Parma. The STs' answers were obtained from the patient's clinical information. A patient was considered frail if at least one of the CGAs' tests resulted positive.
Results: The ST was associated with the CGA's judgement with an Area Under the Curve of 0.691 (CI 95%: 0.591-0.791). Each CGA's test was associated with the ST total score. The five key-question showed a potential discriminating power in the CGA's tests of the corresponding domains. The fall-related question of the ST was significantly associated with the Short Physical Performance Battery total score (OR: 0.839, CI 95%: 0.766-0.918), a proxy of the risk of falling.
Discussion: The results suggest that the ST can capture the complexity of frailty. The ST showed a good discriminating power, and it can guide a second-level assessment to key frailty domains and/or clinical pathways.
Conclusions: The ST is a valid and easy-to-use instrument for the screening of frailty.
