Cost-effectiveness of the Concord Minimal Trauma Fracture Liaison service, a prospective, controlled fracture prevention study
- 1k Downloads
We evaluated the cost-effectiveness of a fracture liaison service prospectively designed to have a parallel control group treated by standard care. The clinical effectiveness of this service was associated with an incremental cost-effectiveness ratio versus standard care of Australian dollars (AUD) 17,291 per quality-adjusted life year (QALY) gained.
Osteoporotic fractures are a major burden for national health services. The risk of re-fracture following an osteoporotic fracture is particularly high. In a study unique in prospectively having a control group treated by standard care, we recently demonstrated that a Minimal Trauma Fracture Liaison (MTFL) service significantly reduces the risk of re-fracture by 80%. Since the service involves greater use of resources, we have now evaluated whether it is cost-effective.
A Markov model was developed that incorporated fracture probabilities and resource utilization data (expressed in AUD) obtained directly from the 4-year MTFL service clinical study. Resource utilization, local cost and mortality data and fracture-related health utility data were used to calculate QALYs with the MTFL service and standard care. Main outcome measures were: additional costs of the MTFL service over standard care, the financial savings achieved through reduced fractures and changes in QALYs associated with reduced fractures calculated over a 10-year simulation period. Costs and QALYs were discounted at 5% annually. Sensitivity analyses quantified the effects of different assumptions of effectiveness and resource utilization associated with the MTFL service.
The MTFL service improved QALYs by 0.089 years and led to increased costs of AUD 1,486 per patient versus standard care over the 10-year simulation period. The incremental cost-effectiveness ratio versus standard care was AUD 17,291 per QALY gained. Results were robust under all plausible assumptions.
The MTFL service is a cost-effective intervention to reduce recurrent osteoporotic fractures.

The MTFL service was supported by logistic support from Concord Repatriation General Hospital, by a Research Entry Grant from the Osteoporosis Australia/The Royal Australasian College of Physicians and by unrestricted research and educational grants from Sanofi-Aventis, Novartis Pharma and Merck Sharp & Dohme (MSD) Pharmaceuticals, Australia. The authors would like to acknowledge the contributions of Drs. Lih, Yap, Nandapalan, Lee, and Ganda in running the MTFL service at Concord Hospital, Sydney. MC was supported by a University of Sydney International Visiting Research Fellowship.
