The Effectiveness of National Early Warning Score (News) as Predictor of Mortality in Heart Failure Patients in Emergency Department

Abstract

Introduction: Heart failure is one of the global health problems for society characterized by a high mortality rate, increased hospitalization and rehospitalization. National Early Warning Score (NEWS) is one who has the EWS development of physiological parameters include pulse rate, systolic blood pressure (SBP), respiratory rate, body temperature, level of consciousness (AVPU), oxygen saturation and the use of supplemental oxygen in the range of 0-3 on each parameter Objective : This study aimed to analyze NEWS effectiveness as a predictor of mortality of heart failure patients in the Emergency Department (ED)of General Hospital of Dr. Slamet Martodirdjo Pamekasan. Method : This study using observational analytic design with prospective cohort approach. The respondents in this study were 64 patients in quota sampling. The research instrument is observation sheet. ROC analysis and multivariate used multiple logistic regression test Results : ROC test showed that NEWS has value of p=0.000 and AUC of 0.856 which describes NEWS can be a strong predictor related mortality in heart failure patients with CI of 95%, sensitivity value of 0.85 (85%) and specificity of 0.818 (81.8%). Logistic regression analysis explained the SBP became independent variables that most associated with mortality of heart failure patients with Exp(B) of 10.208 which describes the high score of SBP has greater risk 10.208 times to death compared with a normal score of SBP after controlled by SPO 2 . Conclusion : NEWS is an effective predictor of mortality of heart failure patients.
