BACKGROUND AND OBJECTIVES: Recommendations to refer pancreatic procedures to high-volume centers have been in place for a decade. We sought to determine whether regionalization of pancreatic procedures to high-volume centers is occurring in Illinois. METHODS: We compared pancreatic procedures performed in Illinois hospitals from 2000 to 2004 [time period (TP) 1] versus 2005-2009 (TP2) for changes in inpatient mortality and hospital volume. Hospitals were categorized into low- (LVH), intermediate- (IVH), or high-volume (HVH). RESULTS: From TP1 to TP2, there was a 23% increase in absolute case volume (2,232-2,737), despite fewer hospitals performing pancreatic procedures (114-95). In hospital mortality decreased (5.5-3.3%, P < 0.01) and was lowest at HVHs. LVHs and IVHs were associated with a 4.7 and 3.0 higher odds of mortality, respectively (both P < 0.001). Overall, HVHs performed 659 (+73%) more procedures, whereas cumulative procedure volume dropped by 154 cases at LVHs (+1%) and IVHs (-18%). CONCLUSIONS: We observed limited evidence of regionalization of pancreatic procedures in Illinois. The increase in HVH case volume cannot be solely attributed to regionalization, given the corresponding modest decrease seen at non-HVHs. There is opportunity for Illinois hospitals to implement strategies such as selective referral to improve mortality after pancreatic resection.
