Relation between Length of Stay with Age, White Blood Cell, Lymphocye, Neutrophil and Ratio Neutrophil Lymphocyte in Geriatric Patients with SIRS at Sanglah Hospital on June 2011-April 2012

Objective: Infection in geriatric patients can increases morbidity and mortality rate. There were several study that confirm the using of white blood cell and ratio neutrophil lymphocyte count as a parameter of systemic inflammations in critically ill patients. The aim of this study is to determine the relation between mortality with age, white blood cell, lymphocyte, netrophil, ratio neutrofil limfosit in geriatric patients with SIRS. Methods: This is a analytics observational retrospective study and data was taken from medical record. The study population included patients aged ＞60 years hospitalised in Sanglah Hospital between Juni 2011 to April 2012 and fulfill criteria for SIRS (temperature ＞38°C or ＜36°C, heart rate ＞90 beats/ minute, respiratory rate ＞20 beath/ minute or PC02 ＜32, WBC ＞ 12x109/L or ＜ 2x109/L). All statistical analyses were conducted with SPSS version 21. Results: A total 126 patients (aged from 60-105 years, with a mean 72,06 years) were followed. The patients is 75 (59,5%) male and 51 (40,5%) female. The neutrophil count is range from 0,6-57,9 x 103/uL, the lymphocyte count is range from 0,2-11,6 x 103/uL. Ratio neutrophil and lymphocyte range from 0,52-78,5. There was no significant correlation between white blood cell, lymphocyte, ratio neutrophil lymphocyte and length of stay based on bivariate analysis. Using multivariate linier analysis, we found that age and neutrophil can be used as weak predictor to length of stay (adjusted R=0,02) Conclusions: There's no significant correlation between white blood cell, lymphocyte and ratio neutrophil lymphocyte geriatric patient with SIRS. But we can use age and neutrophil to predict length of stay.
