Higher Hospital Costs Do Not Result in Lower Readmission Rates Following Total Joint Arthroplasty.

Introduction: Hip and knee arthroplasty are high volume, clinically successful, but costly orthopedic surgical procedures. There is significant variation in volume, outcomes, and cost at various hospitals.

Methods: Using the Statewide Planning and Research Cooperative System (SPARCS) database to determine readmission rates and the New York State Department of Health (NYSDoH) hospital cost transparency database to obtain costs, we reviewed this data for hip and knee replacements to determine if there was a relationship between volume of procedures performed and cost or readmission rates.
