Riesgo de mortalidad según el índice de Charlson en comparación con el índice de fragilidad en pacientes adultos mayores del Centro Médico Naval entre los años 2010 al 2015

Abstract

Objective: To quantify the risk of mortality using the Frailty Index, the Charlson Comorbidity Index and the Short Physical Performance Battery (SPPB) in elderly patients. Such three instruments are useful to assess and subsequently manage this group of patients. Materials and methods: An observational, cross-sectional and analytical study conducted from a secondary database analysis with a non-probability, convenience sampling. The database was collected from the original study “Prevalence and factors associated with frailty in Peruvian older adults” carried out between 2010 and 2015 in the Geriatrics Department of the Centro Médico Naval “Cirujano Mayor Santiago Távara.” A total of 1,897 participants over 60 years old were included. Results: Fragility values accounted for 51.33 %, 26.16 % and 73.47 %, according to the Frailty Index, the SPPB and the Charlson Comorbidity Index, respectively. The mortality rate in the study was 10.13 %. Conclusions: The three instruments compared in this study were significant to predict fragility. However, when a sexadjusted analysis was performed, the SPPB and the Charlson Comorbidity Index showed greater statistical significance.
