The purpose of this study was to determine the role of age and co-morbid disease in predicting major outcomes in acute pancreatitis. Data points were collected according to a predefined electronic data collection form. Acute pancreatitis and its complications were defined according to the revised Atlanta classification. Univariable and multivariable analyses were conducted using Cox proportional hazard regression and multiple logistic regression. From June 2013-February 2015, 1655 adult patients were recruited from 23 centres across Spain. Co-morbid disease, obesity, open surgical necrosectomy within 30 days, and pancreatic necrosis were independently associated with both 30-day mortality and persistent organ failure (p 85 years) was associated with mortality (p  0.05). Comorbidity and obesity are important determinates of mortality and persistent organ failure in acute pancreatitis, but in the absence of organ failure they do not appear to independently contribute to morbidity. This has important implications for severity classification and predictive models of severity in acute pancreatitis.enAcute pancreatitiscomorbiditiescomorbiditymorbiditymortalityorgan failureresearch article30574321open access10.1177/2050640618798155PMC6297924https://journals.sagepub.com/doi/pdf/10.1177/2050640618798155https://pmc.ncbi.nlm.nih.gov/articles/PMC6297924/pdf
