Summary
The efficacy of interventions used in real life for the treatment of osteoporosis has not been evaluated on a national basis. We analysed the database of the single Hungarian health care provider between 2004 and 2010. A marked reduction in fracture incidence and hospitalization was seen, which also proved to be cost-effective.
Introduction
Osteoporosis and its consequences place a significant burden on the health care systems of developed countries. Present therapeutic modalities are effective in reducing the risk of fractures caused by osteoporosis. However, we do not know whether the interventions introduced in the past 15 years have significantly reduced the number of osteoporotic fractures in real life, and if yes, how cost-effectively.
Methods
The database of the National Health Insurance Fund Administration in Hungary was analysed for the period between 2004 and 2010. Two specific patient groups were identified within the population. Patients, who were under osteoporosis treatment in more than 80 % of the potential treatment days in three consecutive years (patients with high compliance), were compared with patients where this ratio was under 20 % (patients with low compliance). Several statistical comparative models were implemented in order to capture a complete picture on the differences. Because of natural data heterogeneity of administration databases, propensity matching was applied as well.
Results
Comparing treated vs. control subjects, patients with high compliance showed a significant decrease in fracture risk and hospitalization, which was more robust after propensity adjustment. On the basis of the observed statistically significant differences, cost-effectiveness analysis was implemented. Utility loss due the observed fractures was compared with the total cost differences of the two arms based on modelling. Our calculations proved the cost-effectiveness of the long-term high compliance in real world settings.
Conclusion
Our findings infer that the standardized and uniform health care of osteoporotic patients in a country may reduce general fracture incidence and hospitalization in a cost-effective way.
