Bisphosphonates : a cost benefit analysis patient (original) (raw)
Introduction: Osteoporotic hip fractures are common in elderly. There is increased risk of sustaining other fractures that incur financial burden on the health system. Prescription of bisphosphonates after osteoporotic hip fracture surgery has been shown to reduce the overall incidence of re-fractures. Methods: All osteoporotic hip fractures treated surgically in Mater Dei Hospital in the year 2011 were analysed in this observational retrospective study. The inclusion criteria were all primary osteoporotic hip fractures. The initiation, or not, of anti-osteoporotic treatment upon discharge from hospital was reviewed. The mortality and re-fracture rate of this cohort was reviewed for a period of 3 years. The cost of hospitalization for hip fracture and re-fractures was calculated based on local health services costs and compared to the benefits of providing a free bisphosphonate medication to each patient. Results: The osteoporotic hip fracture care pathway did not include initiation of anti-osteoporotic therapy after operations. A re-fracture rate of 11.7% over three years predominantly in female patients was observed. In the first year following hip fracture, an estimated direct medical health expenditure due to re-fractures was of €37,642.55-€48,835.19. Conclusion: Prescribing a bisphosphonate has been found to reduce both the re-fracture and mortality rates. In our study, a bisphosphonate prescription could have reduced the all cause mortality rate of 25.3% to 15.18% over the first year of hip fracture, as well as reduced the financial and social burden incurred due to a re-fracture.
