Aging and direct medical costs of osteoporotic fractures

Introduction This study estimated the direct medical costs of osteoporotic fractures from a large claims database in Korea. Materials and methods We compared the medical costs of hip, vertebral, and wrist fractures between two age groups (50-64 years vs 65 years and older). We used a generalized linear model to investigate the drivers of osteoporotic fracture medical costs. Results Hip fractures had the highest costs, regardless of age, followed by vertebral and wrist. The cost of hip fracture was USD 7285 for those aged 65 years and over and USD 6589 for those aged 50-64 years. The length of hospital days was higher in hip fracture patients, regardless of age, followed by vertebral and wrist. As the number of hospitalizations increased, the medical cost increased by 33.0% (p < 0.0001). Patients older than 65 years who were hospitalized for a fracture had a longer total length of hospital stay, compared to patients aged 50-64, regardlessness of the site of the fracture. The cost of treating fractures among those 65 years and older increased by 31.8% compared to those 50-64 years old (p < 0.0001). The direct medical costs increased by 8.6% as the number of fractures increased (p = 0.041). Conclusions We identified that osteoporotic fracture-related medical costs and hospitalization days increased with age. Interventions are effective in reducing fracture risk the potential to yield substantial cost savings.

Automated summary

The study found that direct medical costs and hospitalization days related to osteoporotic fractures increased with age. Interventions to reduce fracture risk are effective and have the potential to yield substantial cost savings.
