The health and economic burden of osteoporotic fractures in Singapore and the potential impact of increasing treatment rates through more pharmacological options

Abstract

Purpose: This study aims to estimate the health and economic burden of osteoporosis in Singapore from 2017 to 2035, and to quantify the impact of increasing the treatment rate of osteoporosis. Methods: Population forecast data of women and men aged 50 and above in Singapore from 2017 to 2035 was used along with prevalence rates of osteoporosis to project the osteoporosis population over time. The population projections by sex and age group were used along with osteoporotic fracture incidence rates by fracture type (hip, vertebral, other), and average direct and indirect costs per case to forecast the number of fractures, the total direct health care costs, and the total indirect costs due to fractures in Singapore. Data on treatment rates and effects were used to model the health and economic impact of increasing treatment rate of osteoporosis, using different hypothetical levels. Results: Between 2017 and 2035, the incidence of osteoporotic fractures is projected to increase from 15,267 to 24,104 (a 57.9% increase) F 10,717 to 17,225 (a 60.7% increase) and M 4550 to 6878 (a 51.2% increase). The total economic burden (including direct costs and indirect costs to society) associated with these fractures is estimated at S$183.5 million in 2017 and is forecasted to grow to S$289.6 million by 2035. However, increasing the treatment rate for osteoporosis could avert up to 29,096 fractures over the forecast period (2017–2035), generating cumulative total cost savings of up to S$330.6 million. Conclusion: Efforts to improve the detection, diagnosis, and treatment of osteoporosis are necessary to reduce the growing clinical, economic, and societal burden of fractures in Singapore.
