Interventions to Increase Osteoporosis Treatment in Patients with ‘Incidentally’ Detected Vertebral Fractures

Abstract

BackgroundMost vertebral compression fractures are not recognized or treated. We conducted a controlled trial in older patients with vertebral fractures incidentally reported on chest radiographs, comparing usual care with osteoporosis interventions directed at physicians (opinion-leader-endorsed evidence summaries and reminders) or physicians+patients (adding activation with leaflets and telephone counseling). MethodsPatients aged >60 years who were discharged home from emergency departments and who had vertebral fractures reported but were not treated for osteoporosis were allocated to usual care (control) or physician intervention using alternate-week time series. After 3 months, untreated controls were re-allocated to physician+patient intervention. Allocation was concealed, outcomes ascertainment blinded, and analyses intent-to-treat. Primary outcome was starting osteoporosis treatment within 3 months. ResultsThere were 1315 consecutive patients screened, and 240 allocated to control (n=123) or physician intervention (n=117). Groups were similar at baseline (average age 74 years, 45% female, 58% previous fractures). Compared with controls, physician interventions significantly (all P <.001) increased osteoporosis treatment (20 [17%] vs 2 [2%]), bone mineral density testing (51 [44%] vs 5 [4%]), and bone mineral density testing or treatment (57 [49%] vs 7 [6%]). Three months after controls were re-allocated to physician+patient interventions, 22% had started treatment and 65% had bone mineral density testing or treatment (P <.001 vs controls). Physician+patient interventions increased bone mineral density testing or treatment an additional 16% compared with physician interventions (P=.01). ConclusionsAn opinion-leader-based intervention targeting physicians substantially improved rates of bone mineral density testing and osteoporosis treatment in patients with incidental vertebral fractures, compared with usual care. Even better osteoporosis management was achieved by adding patient activation to physician interventions [NCT00388908].
