Abstract
BACKGROUND:
Acute and chronic pancreatitis have been associated with significant burden of disease. Recent studies have shown a rise in acute pancreatitis (AP) incidence in western countries. We report population based trends over a 20-year period in the incidence, survival, and costs in acute pancreatitis and chronic pancreatitis (CP) in the United States.
METHODS:
We used data from the National Inpatient Sample and the Nationwide Inpatient Sample (NIS), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality to identify patient discharges between 1993 and 2013. Appropriate International Classification of Diseases, 9th Revision (ICD-9) diagnosis codes were used to isolate AP and CP cases.
RESULTS:
In 1993, the number of acute pancreatitis admissions registered was 144,350. In 2013, this number rose to 274,775 representing an increase of 90.3%. Over this 20-year time period, CP admissions declined from 19,275 in 1993 to 13,385 in 2013 (30.6% decrease). Within the same time period, median charges per person increased for AP from $7,213 to $21,540 (198.6% increase). Similarly, median charges per person for CP increased from $6,654 to $21,083. In-patient mortality decreased from 2.34% in 1993 to .76% in 2013 for AP and from .96% in 1993 to .59% in 2010 for CP.
CONCLUSIONS:
Over the past two decades, there have been considerable increases in AP admissions in the US and a simultaneous slight decrease in CP admissions. This trend is likely to continue in the near future and suggest a need for a better understanding of pancreatitis pathogenesis and risk factors.
