Association of Hospital Market Concentration With Costs of Complex Hepatopancreaticobiliary Surgery.

ABSTRACT:

Importance

Trade-offs involved with market competition, overall costs to payers and consumers, and quality of care have not been well defined. Less competition within any given market may enable provider-driven increases in charges.

Objective

To examine the association between regional hospital market concentration and hospital charges for hepatopancreaticobiliary surgical procedures.

Design, setting, and participants

This study included all patients undergoing hepatic or pancreatic resection in the Nationwide Inpatient Sample from January 1, 2003, through December 31, 2011. Hospital market concentration was assessed using a variable-radius Herfindahl-Hirschman Index (HHI) in the 2003, 2006, and 2009 Hospital Market Structure files. Data were analyzed from November 19
