Rapid Emergency Medicine Score and HOTEL Score in Geriatric Patients Admitted to the Emergency Department

Abstract

Emergency risk scoring systems have been defined in order to identify the health status of the patients on admission to the emergency department. In this study, we aimed to investigate the prognostic values of Rapid Emergency Medicine Score (REMS), REMS without age and the HOTEL scores in geriatric patients. This prospective, single-centered, observational study was carried out between the January 15, 2014 February 28, 2014. Patients admitted to the emergency department during the study period and aged 65 years or older were included in the study. In total, 939 patients were included in the study. In predicting the intensive care unit admission, the area under the curve values of the REMS, REMS without age, and HOTEL scores were 0.772, 0.760, and 0.827 ( p < 0.001, for all), respectively. The median (interquartile range) REMS and REMS without age scores of the nonsurvivors were statistically significantly higher than those of the survivors [10 (6) vs. 6 (3), 5 (6) vs. 1 (2), respectively; p < 0.001 for both]. Similarly, the HOTEL scores of the nonsurvivors were also statistically significantly higher than those of the survivors [2 (1) vs. 1(1), p < 0.001]. In predicting the in-hospital mortality, the area under the curve values of the REMS, REMS without age and HOTEL scores were 0.833, 0.819, and 0.858 ( p < 0.001 for all), respectively. The REMS, REMS without age, and the HOTEL scores cannot be efficiently employed to discriminate geriatric patients requiring hospitalization. Nonetheless, all three scores are proper predictive systems regarding intensive care unit admission and in-hospital mortality in geriatric emergency department patients.
