To describe a method of reducing the costs of implants in hip and knee arthroplasty.
Implant costs were compared before and after the implementation of a 2-year contract with implant vendors, providing increased volume for decreased implant cost. An additional 20% of arthroplasties could be done outside the contract for research or special purposes.
A regional health authority involving 2 acute care hospitals.
Costs were obtained for 942 hip and knee arthroplasties performed in 1993/94 and compared with costs of 1656 hip and knee arthroplasties performed in 1996/97.
Implant cost and number of joint arthroplasty procedures performed.
A 40% decrease in the cost per implant for primary knee arthroplasty and an 18% decrease in the cost per implant for primary hip arthroplasty were achieved. A rebate, calculated as a percentage of volume used, was received from the vendor to support general orthopedic research and education. A new contract for 3 years has recently been signed with 3 vendors designated as primary vendors for 80% of the volume.
The vendor-contract economic strategy effectively reduced the cost of hip and knee arthroplasty and may be useful at other centres looking for cost reduction methods that maintain adequate patient care and support clinical research and education.
描述一种降低髋关节和膝关节置换术中植入物成本的方法。
在与植入物供应商签订为期两年的合同前后对植入物成本进行比较，合同规定增加采购量以降低植入物成本。另外20%的关节置换手术可在合同范围外进行，用于研究或特殊目的。
一个涉及两家急症护理医院的地区卫生当局。
获取1993/94年进行的942例髋关节和膝关节置换手术的成本，并与1996/97年进行的1656例髋关节和膝关节置换手术的成本进行比较。
植入物成本和关节置换手术的数量。
初次膝关节置换术中每个植入物的成本降低了40%，初次髋关节置换术中每个植入物的成本降低了18%。从供应商处获得了按使用量百分比计算的回扣，以支持一般骨科研究和教育。最近与3家供应商签订了为期3年的新合同，这3家供应商被指定为80%采购量的主要供应商。
供应商合同经济策略有效降低了髋关节和膝关节置换术的成本，对于其他寻求在维持充分患者护理的同时降低成本并支持临床研究和教育的中心可能有用。
