Abstract
Study objective and background: The clinical relevance is a multifactorial judgment from experience. It is used daily by clinicians. In contrast, there is no specific prognostic scale for patients admitted to emergency department (ED) resuscitation room. To evaluate the prognosis among critically ill patients in the emergency department resuscitation room, we propose a visual severity scale score. The main objective of this study was to evaluate the visual severity scale score as a predictor of mortality at 24 hours.
Materials and methods: Prospective monocentric observational study conducted in an urban academic medical centre. The main objective was to evaluate visual analogue scale of severity as a 24-hour mortality predictive score. The primary outcome measure was the area under the receiver operating characteristic (ROC) curve (AUC) for mortality at 24 hours. Secondary criteria were rehospitalization at 28 days, mortality at 28 and 90 days and comparison between visual analogue scale of severity and Simplified Acute Physiology Score (SAPS II) at 24 hours using AUC. ED patients triaged to the resuscitation room from May to July 2010 were included.
Results: 172 patients were included. Visual analogue scale of severity predicted mortality at 24 hours with an AUC of 0.913. AUC for SAPS II was 0.907 without any significant difference. AUC for visual analogue scale of severity and SAPS II were not significantly different for rehospitalization at 28 days, mortality at 28 days and 90 days.
Conclusion: Visual analogue scale of severity is a good score for predicting mortality at 24 hours for critically ill patients in the resuscitation room of an ED.
