Actions to Improve the Secondary Prevention of Fragility Fractures in Women with Postmenopausal Osteoporosis: A Social Return on Investment (SROI) Study.

PURPOSE

This study evaluates the Social Return on Investment (SROI) of implementing measures to prevent fragility fractures in postmenopausal women with osteoporosis (OP) in Spain.

METHODS

A group of 13 stakeholders identified necessary actions for improving refracture prevention and assessed the investment required from the Spanish National Health System (SNHS), considering direct, indirect, and intangible costs over a one-year period. Unitary costs were sourced from scientific literature and official data, and intangible costs were estimated through surveys on women's willingness to pay for better health-related quality of life. The SROI ratio was calculated from both a social perspective (including all returns) and the SNHS perspective (including only direct and intangible costs). A sensitivity analysis evaluated the returns in worst- and best-case scenarios over three years.

RESULTS

Stakeholders agreed on four main actions: 1) establishing fracture liaison services; 2) harmonizing clinical practice guidelines and provide training for healthcare professionals (HCPs); 3) promoting HCPs' adherence to fracture registries and 4) raising awareness of OP and fragility fractures. From the social perspective, implementing these actions would cost the SNHS €4,375,663 but yield a social return of €96,939,931 in the first year, resulting in a SROI ratio of €22.15 per euro invested (€28.69, 23.14, 24.29, and 10.70 for the four actions, respectively). From the SNHS perspective, the return would be €36,453,509 (€21,523,444 tangible), with a SROI of €8.33 (€4.92 tangible) and for the four actions: €9.99, 9.39, 8.45, and 3.79, respectively (€5.89, 5.54, 4.96 and 2.27 tangible). The investment would be lower than the return for all actions (3.49%, 4.32%, 4.12% and 9.34% of social perspective return, respectively) and scenarios.

CONCLUSION

According to our SROI method, implementing different actions to improve secondary fracture prevention would achieve a considerable social benefit, which, in terms of direct, indirect, and intangible costs, would far outweigh the investment.
