Validasi Simple Model Score dalamMemprediksi Mortalitas Tujuh Han PerawatanPasien Gawat Darurat Non-Bedah di RumahSakit Cipto Mangunkusumo, Jakarta
ABSTRACT
Background: Patients visit emergency department (ED) with varying diagnosis and severity spectrums. Simple Model Score (SAS) utilizes age and laboratory data to stratify the risk of ED patients and predict their mortally. SMS proves to perform well but its application on population with different characteristics has to be validated.
Objective: To evaluate the calibration and discrimination of SMS in predicting seven day in-hospital mortality ofnon-surgkal ED patients at Cipto Markgunkusumo Hospital PAK Jakarta.Methods:A validation study with retrospective cohort designed was performed on non-surgical pollens. in ED of CMHduring October-November 2012. The data on age, hemoglobin, platelet count, white bloodcount,ureum,sodium,andblood glucose level at admission to ED were used to calculate 5145.The primaryout comewassevenday in-hospitalmortality. Calibration was evaluated using calibration plot and Hosmer-lemeshow test while discrimination wasevaluated with area under the curve (AUC).
Results; A total of 701 patients were recruited. Mortality was observed in 92 patients (13.12%). Calibration plot ofSMS showed r =0.64 and Hosmer-Lemeshow test showed p = 60.7.5. Discrimination was shown by ROC curve with AUC0.67(C1 95% 0.610-0.719).
Conclusion; SMSshowed good calibration but less satisfying discrimination in predicting seven day in-hospitalmortality of non-surgical ED patients at CHM
