The relationship of hospital market concentration, costs, and quality for major surgical procedures.

Journal Article

BACKGROUND:Our objective was to determine the association between indicators of surgical quality - incidence of major complications and failure-to-rescue - and hospital market concentration in light of differences in costs of care. METHODS:Patients undergoing coronary artery bypass graft (CABG), colon resection, pancreatic resection, or liver resection in the 2008-2011 Nationwide Inpatient Sample were identified. The effect of hospital market concentration on major complications, failure-to-rescue, and inpatient costs was estimated at the lowest and highest mortality hospitals using multivariable regression techniques. RESULTS:A weighted total of 527,459 patients were identified. Higher market concentration was associated with between 4% and 6% increased odds of failure-to-rescue across all four procedures. Across procedures, more concentrated markets had decreased inpatient costs (average marginal effect ranging from -$3064 (95% CI: -$5812 - -$316) for CABG to -$4876 (-$7773 - -$1980) for liver resection. CONCLUSION:In less competitive (more concentrated) hospital markets, higher overall risk of failure-to-rescue after complications was accompanied by lower inpatient costs, on average. These data suggest that market controls may be leveraged to influence surgical quality and costs.
