Neutrophil-to-Lymphocyte Ratio as an Early Predictor of Complication and Mortality Outcomes in Individuals With Acute Pancreatitis at a UK District General Hospital: A Retrospective Analysis.

Aim The purpose of this study was to evaluate the predictive usefulness of the neutrophil-to-lymphocyte ratio (NLR) in patients with acute pancreatitis (AP) and establish a threshold for the prediction of poor outcomes. Methods For this investigation, we looked back at all cases of acute pancreatitis treated at Torbay Hospital in Torquay, UK, between January 1st, 2019, and December 31st, 2020. Those who were found to have chronic pancreatitis or whose baseline laboratory values could not be obtained were not included. Each patient's entire hospital stay was analyzed, including up to 72 hours of medical and laboratory data. Results According to the Glasgow Coma Scale scoring system, 28 of the 314 included patients had severe acute pancreatitis, and 81 patients had pancreatitis with complications. Those with complications had a substantially higher NLR on day 1 (9.43 ± 7.57) than patients who recovered without complications (7.37 ± 5.88) (P-value = 0.028). The NLR on day 0 (>18.71) exhibited a sensitivity of 80%, a specificity of 90.2%, and an accuracy of 83.9% in forecasting the death of patients with pancreatitis. Conclusion Elevated baseline NLR corresponds with pancreatitis with complications and can predict mortality.
