Aim: The present study was conducted with aim to determine the correlation of red blood cell distribution width (RDW) with mortality in patients of acute pancreatitis (AP). Materials and Methods: This was a prospective, observational study conducted among the 100 patients, admitted in the Department of Medicine, PBM Hospital, Bikaner, with a definite diagnosis of AP, confirmed both clinically and radiologically. Patients were enrolled justifying predefined inclusion and exclusion criteria. All routine investigations such as complete blood chemistry including RDW, renal function test, liver function test, and random blood sugar, more specific ones such as serum amylase and lipase, and contrast-enhanced computed tomography of abdomen were performed both at the time of admission and discharge. Receiver operating characteristic and logistic regression analyses were employed for evaluation. Results: Of 100 patients, 69% were male whereas 31% were female. The predominant etiology of AP in our study was cholelithiasis (64%). Mean RDW on the day of presentation and discharge was 14.10 ± 3.12 and 13.56 ± 1.34, respectively. Among the total 38 patients of mild AP, 47.36% (18) had RDW <12.6, 44.7% (17) had RDW ranging from 12.6 to 13.3, whereas only 7.89% (3) had RDW >13.3. From the 62 patients of severe AP, 91.9% had RDW >13.3 and 8.1% had RDW ranging from 12.6% to 13.3%. The total mortality rate of our study was 4%. Conclusion: It was seen that most of the patients who had severe AP have high RDW. Of the four patients that expired, three had RDW >13.3. Thus, RDW increases with the severity of pancreatitis, which was statistically significant and correlated with mortality among acute AP patients. Hence, RDW can be considered as a convenient, time, and cost-effective method.
