Acute pancreatitis in elderly patients: a single-center retrospective evaluation of clinical outcomes

INTRODUCTION:Acute pancreatitis (AP) incidence in the elderly population has increased in the last years. However, the role of age as influencing factor on the AP clinical course is still debated.METHODS:We reviewed clinical records of consecutive patients admitted with diagnosis of AP. Patients were divided in elderly (≥65 years) and non-elderly  (<65 years). Primary endpoint was comparison of overall mortality. Secondary endpoint included ICU admission, in-hospital length of stay (LOS) and surgical procedures.RESULTS:We enrolled 352 elderly and 532 non-elderly patients. A higher mortality rate (7.4% vs 1.9%; p < .001), ICU admission rate (18.9% vs 6.3%; p < .001) and prolonged length of hospital stay (9 (6-14) vs 7 (5-11.7) days; p = .01) were registered in the ≥65 years group. Multivariate analysis identified age (OR: 3.5; 95% CI:1.645-7.555; p = .001), a higher Ranson score at admission (OR: 5.52; 95% CI:1.11-27.41; p<.001) and necrotic pancreatitis (OR: 8.6; 95% CI:2.46-30.27; p = .001) as independent predictors of mortality. Conversely age and necrotic pancreatitis were independent risk factors for higher LOS and ICU admission.CONCLUSIONS:Patients with AP and age ≥65 years have a higher mortality, ICU admission and prolonged LOS. Early recognition and prompt treatment are key elements to improve outcomes in this population.
