Abstract
Shared decision-making (SDM) aims to improve patients’ experiences with care, treatment adherence, and health outcomes. However, the effectiveness of SDM in patients with a recent fracture who require anti-osteoporosis medication (AOM) is unclear. The objective of this study was to assess the effectiveness of a multicomponent adherence intervention (MCAI) including a patient decision aid (PDA) and motivational interviewing at Fracture Liaison Services (FLS) on multiple outcomes compared with usual care (UC). This pre-post superiority study included patients with a recent fracture attending FLS and with AOM treatment indication. The primary outcome was 1-year AOM persistence measured by pharmacy records. Secondary outcomes included treatment initiation, AOM adherence (measured by medication possession ratio [MPR]), decision quality (SDM process; 0–100, best), and decisional conflict (0–100, highest conflict), subsequent fractures, and mortality. Outcomes were tested in MCAI and UC groups at the first FLS visit and 4 and 12 months afterwards. Multiple imputation and uniand multivariable analyses were performed. Post hoc analyses assessed the role of health literacy level. In total, 245 patients (MCAI: n = 136, UC: n = 109) were included. AOM persistence was 80.4% in the MCAI and 76.7% in the UC group (p=.626). SDM process scores were significantly better in MCAI (60.4 vs 55.1; p = .003). AOM initiation (97.8% vs 97.5%), MPR (90.9% vs 88.3%, p=.582), and decisional conflict (21.7 vs 23.0; p = .314) did not differ between groups. Results did not change importantly after adjustment. Stratified analyses by health literacy showed a better effect on MPR and SDM in those with adequate health literacy. This study showed no significant effect on AOM persistence; however, it demonstrated a significant positive effect of MCAI on SDM process in FLS attendees.

We wanted to study how shared decision-making works in people who recently broke a bone and therefore needed anti-osteoporosis medication. We looked at 2 approaches that specialized nurses could use at the clinic. During the first visit, the nurses used a decision aid to discuss different medication options with the patient. During the second visit, nurses used “motivational interviewing” to better understand and support patients with taking their medication in the long term. We compared 109 patients who participated in this study with 126 patients who received normal care without the approaches. We found t
