Fatal Acute Pancreatitis Occurring Outside of the Hospital: Clinical and Social Characteristics

Abstract

Mortality caused by acute pancreatitis in patients admitted to the hospital has been thoroughly investigated, but knowledge regarding outpatient fatalities is far from complete. The purpose of this study was to assess the incidence and clinical characteristics of patients who have died due to acute pancreatitis occurring outside the hospital. Deaths caused by acute pancreatitis in the southern part of Sweden during 1994-2008 were identified at the Department of Forensic Medicine, Lund. A retrospective review of all cases was performed. A total of 50 patients were included, representing approximately 50 of 292 (17%) of all deaths due to acute pancreatitis in the region during this period of time. Median age was 54 (47-69) years and the majority-37 (74%)-were men. The main etiology was alcohol, seen in at least 35 (70%) patients. Twelve (24%) patients were obese. The duration of abdominal pain, in evaluable cases, was 3.0 (1.6-6.2) days. Profound signs of pancreatitis were seen in all patients; 35 (70%) had a necrotising disease according to histopathological examination. Pulmonary changes were common, e.g., bronchopneumonia, pleural effusion, or edema, and all but four had fatty liver. Massive intra-abdominal bleeding was seen in one patient. At least eight patients had a mental disorder, and three were homeless. Fatal acute pancreatitis occurring outside the hospital accounts for a substantial part of all deaths due to the disease. The incidence seems to decline, and no variation in season was seen. Alcohol was the predominant etiology. Many of the patients lived alone and in poor social conditions.
