Abstract

Background Acute pancreatitis (AP) represents a common gastrointestinal disorder. Complicated disease courses in particular still represent a major clinical challenge and are associated with high mortality. Evaluation of existing data sets and their careful interpretation can support a rational discussion to optimize outcomes of this common gastrointestinal disease. Methods We used standardized hospital discharge data provided by the Federal Statistical Office of Germany to evaluate hospital mortality and current developments of AP in Germany between 2008 and 2017. Results In this analysis, 516,618 hospitalized AP cases were included. Main disease etiologies featured biliary (29.9%) and alcoholic (22.7%) AP. The annual frequency of AP increased from 48,858 (2008) to 52,611 (2017), mainly due to a rising incidence of biliary AP. Average hospital mortality was 2.85% and significantly improved over time. While uncomplicated AP had low hospital mortality (1.38%), the presence of organ complications was associated with a mortality of 12.34%. The necessity of mechanical ventilation dramatically increased hospital mortality to 44.06%. Hospital mortality was significantly higher in female patients (3.31%) than males (2.55%) and showed a stepwise increase with patient age. We further identified type 2 diabetes mellitus and obesity as factors associated with increased hospital mortality. Hospital mortality was lowest among patients treated at departments specializing in gastroenterology. Finally, high case volume centers (defined as >98 annual AP cases) had the lowest hospital mortality for patients with complicated courses of AP. Conclusion With over 50,000 annual hospitalization cases, AP is one of the most important inpatient treatment indications in gastroenterology in Germany. Overall, AP mortality has improved in recent years, presumably due to improved interdisciplinary treatment concepts. In this study, we identified important clinical and epidemiological risk factors for an unfavorable course, which could help to improve risk prediction and triaging, and thus the management of AP.
