Background/objectives: Alcoholic acute pancreatitis (AAP) comprises the second most common cause of acute pancreatitis in the USA, and there is lack of data regarding 30-day specific readmission causes and predictors. We aim to identify 30-day readmission rate, causes, and predictors of readmission.
Methods: Retrospective analysis of the 2016 National Readmission Database of adult patients readmitted within 30 days after an index admission for AAP.
Results: Totally, 76,609 AAP patients were discharged from the hospital in 2016. The 30-day readmission rate was 12%. The main cause of readmission was another episode of AAP. Readmission was not associated with higher mortality (1.3% vs. 1.2%; P = 0.21) or prolonged length of stay (5.2 vs. 5.0 days; P = 0.06). The total health care economic burden was $354 million in charges and $90 million in costs. Independent predictors of readmission were having Medicaid insurance, a Charlson comorbidity index score ≥ 3, use of total parenteral nutrition, opioid abuse disorder, prior pancreatic cyst, chronic alcoholic pancreatitis, and other chronic pancreatitis. Obesity was associated with lower odds of readmission.
Conclusion: Readmission rate for AAP is high and its primary cause are recurrent episodes of AAP. Alcohol and substance abuse pose a high burden on our health care system. Public health strategies should be targeted to provide alcohol abuse disorder rehabilitation and cessation resources to alleviate the burden on readmission, the health care system and to improve patient outcomes.
