Summary

Implementing a vendor contract strategy significantly reduced implant costs for hip and knee arthroplasty by leveraging increased volume for decreased pricing. This approach offers a viable cost-saving method for healthcare facilities.

Area of Science:

  • Orthopedic Surgery
  • Health Economics
  • Medical Device Procurement

Background:

  • Hip and knee arthroplasty implant costs represent a significant expenditure in orthopedic surgery.
  • Previous cost-containment strategies have had variable success in managing these expenses.

Purpose of the Study:

  • To evaluate the effectiveness of a vendor-contracting strategy in reducing implant costs for hip and knee arthroplasty.
  • To assess the impact of volume-based purchasing agreements on implant pricing.

Main Methods:

  • A comparative analysis of implant costs before and after implementing a 2-year vendor contract was conducted.
  • Data from 942 hip and knee arthroplasties (1993/94) were compared with 1656 procedures (1996/97).
  • The study involved a regional health authority across two acute care hospitals.

Main Results:

  • A 40% reduction in primary knee arthroplasty implant cost and an 18% reduction in primary hip arthroplasty implant cost were achieved.
  • A volume-based rebate was secured from the vendor, supporting orthopedic research and education.
  • A subsequent 3-year contract was established with primary vendors for 80% of the volume.

Conclusions:

  • A vendor-contract economic strategy effectively reduced hip and knee arthroplasty implant costs.
  • This model is transferable to other institutions seeking cost-reduction methods.
  • The strategy supports patient care while facilitating clinical research and education.
