Oxid Comparative Analysis of the Significance of BISAP and MEWS Score for an Early Assessment of Illness Severity and Treatment Outcome of Acute Pancreatitis

Abstract

The aim of this study was to determine the significance of the use of the BISAP score, which is specific for patients with AP, in relation to the application of the MEWS score that is important for assessing the condition of critically ill patients in intensive care units, but is not specific for patients with AP. The research was conducted as a cohort prospective study and included pa-tients of both sexes, older than 18 and diagnosed with AP. BISAP and MEWS score were monitored at least at four time points: on admission to the hospital (zero), 48 hours, 72 hours and 7 days after admission to the hospital. High levels of discrimination between patients with fatal out-come and cured patients are determined in both cases, with dis-crimination at MEWS being somewhat higher than BISAP score. The BISAP0 had the best discrimination for BISAP score, AUROC (0.807) and also MEWS0 for MEWS score, AUROC (0.899). In our research, the highest sensitivity was shown by BISAP7d (92.1%) and MEWS48 (88.1%), and a high specificity of 87.5% had BISAP score, 48h, 72h and MEWS score at all four points of measurement. BISAP score has a better prognostic value in relation to the form of pancreatitis, the development of complications and the outcome. However, the calculation of the MEWS score is based on monitoring the basic vital parameters so that its application is much simpler and does not require additional cost
