Background/Purpose: To improve the rate of osteoporosis medication use in women with a prior fracture we developed and implemented a tailored, educational, direct-to-patient video intervention to provide information about reducing fracture risk with osteoporosis medications.
Methods: We conducted a controlled, randomized clinical trial of our novel intervention among US women in the Global Longitudinal Study of Osteoporosis in Women cohort with self-reported fracture history who were not currently using osteoporosis therapy. The primary outcome at 6 months follow-up was self-report of osteoporosis medication use. Secondary outcomes included self-reported use of calcium and vitamin D supplementation and bone density testing. Missing data were treated with multiple imputation and the outcomes (proportions) were compared by chi square test using intent-to-treat analysis.
Results: We randomized 2684 women to receive the intervention materials or usual care. Study participants were 92.6% Caucasian, with a mean (SD) age 74.9 (8.0) years, had some college education (76.7%), in good health (84.6%), and a self-reported lower than average risk for osteoporosis (40.0%). In the 12 months prior to randomization, 1390 women reported talking with their doctor regarding osteoporosis, 7.4% reported a fracture, vitamin D or calcium supplementation were reported as 83.5% and 68.6%, respectively. We observed no differences in sociodemographic characteristics and no significant differences in the primary (11.7% vs 11.4%) and secondary (calcium, 31.8% vs 32.6%; vitamin D, 41.3% vs 41.9%; bone density, 61.8% vs 57.1%) end points between the intervention and usual care groups. Exploratory post-hoc analyses demonstrated that women in the intervention arm had more favorable views towards osteoporosis medications compared with the usual care arm and a lower proportion were in the unaware and uninvolved stages of behavior change regarding osteoporosis medications (64.1.% vs. 68.8%, raw p =0.028). We found that barriers to treatment were higher in the intervention, as compared to usual care arm at 6 months: concerns regarding osteonecrosis of the jaw (28.9% vs 24.6%, raw p=0.031) and difficulty in taking/remembering to take osteoporosis medications (22.0% vs 18.1%, raw p=0.03).
Conclusion: This randomized study testing a novel, personalized educational intervention, did not increase the use of osteoporosis therapy at 6 months. The intervention appeared to have influenced participants’ readiness for behavior change.
