Initiation of bone-health medication in older patients is associated with factors such as female sex, older age, state-funded health cover, and osteoporosis. High fracture risk for hip and all fractures, previous fracture, rheumatoid arthritis, corticosteroid use, and certain comorbidities are also associated with medication initiation. Undertreatment remains a concern, particularly in older patients with multiple conditions.
Background: Adults at high risk of fragility fracture should be offered pharmacological treatment when not contraindicated, however, under-treatment is common. Objective: This study aimed to investigate factors associated with bone-health medication initiation in older patients attending primary care. Design: This was a retrospective cohort study. Setting: The study used data from forty-four general practices in Ireland from 2011-2017. Subjects: The study included adults aged >= 65 years who were naive to bone-health medication for 12 months. Methods: Overall fracture-risk (based on QFracture) and individual fracture-risk factors were described for patients initiated and not initiated onto medication and compared using generalised linear model regression with the Poisson distribution. Results: Of 36,799 patients (51% female, mean age 75.4 (SD= 8.4)) included, 8% (n= 2,992) were observed to initiate bone-health medication during the study. One-fifth of all patients (n= 8,193) had osteoporosis or had high fracture-risk but only 21% of them (n= 1,687) initiated on medication. Female sex, older age, state-funded health cover and osteoporosis were associated with initiation. Independently of osteoporosis and co-variates, high 5-year QFracture risk for hip (IRR= 1.33 (95% CI= 1.17-1.50), P < 0.01) and all fractures (IRR= 1.30 (95% CI= 1.17-1.44), P < 0.01) were associated with medication initiation. Previous fracture, rheumatoid arthritis and corticosteroid use were associated with initiation, while liver, kidney, cardiovascular disease, diabetes and oestrogen-only hormone replacement therapy showed an inverse association. Conclusions: Bone-health medication initiation is targeted at patients at higher fracture-risk but much potential undertreatment remains, particularly in those >80 years and with co-morbidities. This may reflect clinical uncertainty in older multimorbid patients, and further research should explore decision-making in preventive bone medication prescribing.
