Case-fatality from acute pancreatitis is decreasing but its population mortality shows little change

The reasons for changing epidemiology of acute pancreatitis (AP) are poorly defined. We hypothesized that trends for severity, case-fatality and population mortality from AP will provide an insight into the rising burden of AP in the population. We evaluated trends in the hospitalizations, case-fatality, severity and population mortality related to AP in the US population. We used the National Hospital Discharge Survey to calculate age, sex and...
