Diagnostic Test of a Scoring System for Frailty Syndrome in the Elderly According to Cardiovascular Health Study, Study of Osteoporotic Fracture and Comprehensive Geriatric Assessment Based Frailty Index Compared with Frailty Index 40 Items
Aim: to get a recommendation on the best frailty syndrome diagnostic tools, that will be able to be practiced on a daily setting in Indonesia. Methods: this is a cross-sectional study with diagnostic test approach, conducted to patients in the Geriatric Outpatient Clinic of Cipto Mangunkusumo National Referral Hospital on May-June 2013. Each subject underwent a frailty evaluation using CHS, SOF, FI-CGA and FI-40 scoring systems. Then, we calculate the sensitivity, specificity, PPV, NPV, LR+ and LR- of each scoring system compared to FI-40. Results: the proportion of frail, pre-frail and fit according to FI-40 are 25.3%,71% and 3.7% respectively. In terms of differentiation frail to non-frail, CHS had 41.2% sensitivity, 95% specificity, PPV 73.7%, NPV 82.7%, LR+ 8.41 and LR- 0.62. SOF scoring system had 17.6% sensitivity, 99.5% specificity, PPV 92.3%, NPV 78.1%, LR+ 35.2 and LR- 0.83. Furthermore FI-CGA had 8.8% sensitivity, 100% specificity, PPV 100%, NPV 76.4%, LR+ ∞ and LR- 0.91. Conclusion: There is no better scoring system that could be implemented to screen for frailty syndrome other than FI-40 items. However, other scoring systems could be used as a good diagnostic
tool for the syndrome.
Key words: elderly patient, frailty syndrome, CHS index, SOF index, FI-CGA, FI-40.
