Impact of risk factors on the evolution of severe acute pancreatitis

Abstract

Introduction. Severe acute pancreatitis (SAP) is an acute inflammatory condition of the pancreas with increasing incidence and mortality rates in recent years. The aim of this study was to evaluate the impact of age, comorbidities, and different scoring systems on the complications and outcomes of SAP. Materials and Methods. A retrospective study was conducted on 161 patients diagnosed and treated for SAP at the Bucharest University Hospital in the intensive care unit (ICU), in the period 2014-2021. The impact of risk factors for the development of SAP, occurrence of complications (respiratory, cardiac, etc.), length of hospital stays and mortality was analyzed using several scores (BISAP, Ranson, Apache II and SOFA) or modified computed tomography severity index. Preexisting chronic conditions were assessed using the Charlson Comorbidity Index (CCI). Multivariate statistics and non-parametric univariate were calculated in statistical analysis. Odds ratios with 95% confidence intervals were used. Results. Risk factors such as age, diet, medication, alcohol consumption, genetic factors and patient comorbidities contribute significantly to the development of a severe form of acute pancreatitis with critical course and high mortality. Conclusions. In our study, CCI was the most important factor correlated with death and duration of ICU treatment.
