Purpose
A fracture liaison service (FLS) was established in England to support patients with fragility fractures, and it was introduced in Japan as the osteoporosis liaison service (OLS). The study aim was to determine if the Japanese OLS/FLS prevents secondary fractures in patients with fragility fractures and assess the value of the OLS/FLS. Our OLS/FLS evaluated the status of osteoporosis in patients and their life circumstances. Additionally, it introduced osteoporosis therapies during the patients’ hospitalization period and then continued periodical examinations and prescription of drug after discharge.
Patients and methods
This study was conducted in consecutive patients: 400 were assigned to the non-OLS group and 406 to the OLS group. The mean age of the patients was 81.7 ± 9.7 years in the non-OLS group (154 patients with vertebral fractures and 246 with hip fractures; 100 males, 300 females) and 82.4 ± 9.3 years in the OLS group (245 patients with hip fractures and 161 with vertebral fractures; 101 males, 305 females).
Results
During hospitalization, 74.9% of the OLS group patients started medications and 63.9% of patients continued after discharge, while 35.8% and 53.5% of non-OLS group. The incidence rate of secondary fractures was 89.8/1000 person-years in the non-OLS group, and 55.2/1000 person-years in the OLS group. The multivariate Cox hazards test showed that secondary fractures after vertebral or hip fractures increased with age, and the risk was 0.58-fold in patients in the OLS group.
Conclusion
OLS was effective in reducing secondary fractures in patients with osteoporosis with fragility fractures.
