We examined the relationship between hospital case volume and patient outcome (ie, length of hospital stay and hospital charges) for both total hip arthroplasty (THA) and total knee arthroplasty (TKA). The study included 1561 patients who had total joint arthroplasty from April 1, 2001, to March 31, 2003. Using the mean values of THA or TKA surgical case volumes, the participating hospitals were divided into high-volume and low-volume groups. Based on this categorization, the association between hospital surgical case volume and the patient outcome measures was tested. Hospital patient case volume has significant effects on the total length of hospital stay for both THA and TKA and on the total cost for THA. Implications of the findings for practice are considered.
我们研究了全髋关节置换术（THA）和全膝关节置换术（TKA）的医院病例数量与患者预后（即住院时间和住院费用）之间的关系。该研究纳入了2001年4月1日至2003年3月31日期间接受全关节置换术的1561例患者。根据THA或TKA手术病例数量的平均值，将参与研究的医院分为高病例量组和低病例量组。基于这一分类，对医院手术病例数量与患者预后指标之间的关联进行了测试。医院患者病例数量对THA和TKA的总住院时间以及THA的总成本均有显著影响。文中还考虑了这些研究结果对实践的意义。
