Total hip and total knee arthroplasty are high-volume surgical procedures that have a substantial economic impact for the healthcare system. This study analyzes the financial effect of a capitation matrix system on total knee and total hip implant costs over a 1-year period at a community hospital system. The matrix implant levels were based on implant characteristics, correlating increased technological sophistication of the various implants with increased but capitated payment to vendors. In the first year after the implementation of the matrix system, implant costs for the hospital decreased by 26.1% per implant for 369 total hip procedures and also by 26.1% per implant for 934 total knee procedures.
全髋关节置换术和全膝关节置换术是高容量的外科手术，对医疗保健系统有重大的经济影响。本研究分析了在一家社区医院系统中，人头矩阵系统在1年时间内对全膝关节和全髋关节植入物成本的财务影响。矩阵植入物水平基于植入物特征，将各种植入物技术复杂性的提高与向供应商支付的人头费增加相关联。在矩阵系统实施后的第一年，369例全髋关节手术的医院植入物成本每植入物下降了26.1%，934例全膝关节手术的医院植入物成本每植入物也下降了26.1%。
