Abstract
BACKGROUND: Fracture events in older adults are important opportunities for secondary prevention. In response to national (HEDIS) quality metrics in 2008, our medical group implemented a fracture prevention program, identifying women age ≥65y who experienced a fracture and targeting them for osteoporosis screening or treatment within six months. In 2015, we added an outreach program for “high-risk secondary fracture prevention” targeting women age 60-85y and men age 70-85y for osteoporosis therapy within 6 months after a hip, pelvic, humerus, wrist or vertebral fracture. This study examines whether targeting “high-risk fracture” in women and men results in higher treatment rates following a non-vertebral major osteoporotic fracture.
METHODS: This retrospective study was conducted using data from women age 60-85y and men age 70-85y who experienced a fracture of the hip, humerus, and wrist in 2013-2014 (Cohort 1, the era of our HEDIS-only program) or 2015-2016 (Cohort 2, the era of our added “high-risk secondary fracture prevention” program). We excluded patients with primary bone disorders or metastatic cancer and those with osteoporosis treatment in the year prior to fracture. Osteoporosis drug therapy (oral/IV bisphosphonates, denosumab, raloxifene or teriparatide) initiated within six months after the fracture date was assessed. Differences between groups were compared using the chi-squared test, and multivariable logistic regression was used to examine predictors of treatment.
RESULTS: There were 5727 (Cohort 1) and 6469 (Cohort 2) adults identified with hip, humerus, or wrist fracture (high risk fracture). Wrist fracture was the most prevalent fracture in women and hip fracture the most prevalent in men. Osteoporosis treatment initiation within 6 months of the fracture date was achieved for 38% of women and 13% of men in Cohort 1 and 37% of women and 25% of men in Cohort 2. Among women age 60-64, treatment increased from 14% (Cohort 1) to 25% (Cohort 2). Overall, fracture in the later era (2015-2016) was associated with a slightly lower odds of post fracture treatment initiation (adjusted odds ratio OR 0.8, 95% confidence interval (CI) 0.7-0.9) in women 65-85y; however, a much higher odds of treatment was seen (OR 2.3, 95% CI 1.9-2.9) for men 70-85y. Older age, hip fracture, and past osteoporosis therapy were also associated with greater odds of treatment within 6 months.
CONCLUSION: Targeted high-risk fracture intervention resulted in a 2-fold increase in osteoporosis treatment after major non-vertebral osteoporotic fracture in men 70-85y and women 60-64y, the demographic subgroups not previously targeted by HEDIS-based intervention. However, treatment of fractures in women already targeted by HEDIS-based intervention did not increase. Future studies should address potential barriers to treatment and assess the impact of added high-risk fracture outreach on adherence to therapy.
