Background To evaluate temporal trends in gender, etiology, severity, outcomes, cost and median length of stay (MLS) in patients with acute pancreatitis (AP) in a third-tier Chinese city.Methods Patients with AP admitted to a university hospital between January 2013 and December 2021. Relationships between etiology, prevalence of severe acute pancreatitis (SAP) and survey years were investigated by joinpoint regression analysis.Results A total of 5459 (male 62.3%) patients with AP were included. Between January 2013 and December 2021, we observed: (a) the prevalence of biliary diseases-related AP was stable, while the prevalence of hypertriglyceridemia (HTG)-associated AP (Ptrend = 0.04) and alcohol-associated AP (Ptrend < 0.0001) both increased; (b) there was an increase in crude prevalence of SAP from 4.97% to 12.2% between 2013 and 2021 (Ptrend < 0.0001); (c) compared to female populations, male gender had a higher prevalence of AP; (d) there was a decrease in MLS from 11 days to 8 days (Ptrend < 0.0001) and in median cost of hospitalization (MCH) for all patients (from 20,166 to 12,845 YUAN) (Ptrend < 0.0001); (e) the overall in-hospital mortality rate was 1.28% (70/5459) for patients with AP. There was no statistically significant in the time trend of mortality during the study period (Ptrend = 0.5873). At multivariate analysis, survey year was associated with prevalence of SAP after adjustment by age and biliary diseases (OR: 1.07; 95% CI: 1.03–1.12). Based on the stratification by severity of disease, the decrease of MLS and MCH was more significant in non-SAP vs. SAP patients.Conclusions Over the observational period, the proportion of male patients with AP, prevalence of age-adjusted rate of HTG and alcohol-associated AP and SAP increased, while MLS and MCH for all patients decreased, and the time trend of mortality of AP was stable.
