ABSTRACT
This study aims to evaluate the efficacy of an Orthopaedic Surgeon Led Osteoporosis Model of Care (OSLO-MoC) in improving care of patients with primary osteoporotic fractures. The OSLO-MOC has shown to be effective in improving osteoporotic medication initiation and compliance and reducing secondary fracture rates in patients. PURPOSE: This study aims to evaluate the efficacy of an Orthopaedic Surgeon Led Osteoporosis Model of Care (OSLO-MoC) as compared to a Case Manager Led Osteoporosis Model of Care (CMLO-MoC) in reducing early osteoporotic re-fracture rates and treatment compliance in patients. METHODS: This was a single centre, retrospective, comparative cohort study of all patients screened and treated for secondary osteoporotic fracture prevention from the 2008 to 2018 at an orthopaedic surgical unit. From the 2008 to 2013, patients were recruited under the CMLO-MoC and from 2014 to 2018, under the OSLO-MOC. Logistics regression analysis was used to identify significant predictors such as OSLO-MOC implementation, gender, ethnicity, marital status and education level for patient recruitment, treatment compliance and secondary fracture rates at 12-month follow-up. RESULTS: Over a 10-year period, 7388 patients were screened of which 2855 patients were eligible for analysis. A total of 1234 patients were recruited under CMLO-MoC and 1621 patients under OSLO-MOC. Implementation of the OSLO-MOC was associated with greater patient recruitment, OR 1.26 (95%CI 1.06-1.49, P = 0.007). Of the 2855 patients recruited, OSLO-MOC implementation, OR 2.61 (95%CI 2.03-3.36, P < 0.001), and a higher level of education, OR 1.428 (95%CI 1.02-1.43, P = 0.037), were associated with improved compliance to medication at 12 months. OSLO-MOC implementation was the only factor associated with reduced risk of secondary fractures at 12 months, OR 0.14 (95%CI 0.03-0.66, P = 0.013). CONCLUSION: The OSLO-MOC has shown to be effective in reducing the rate of re-fracture and osteoporotic medication initiation and compliance of patients. LEVEL OF EVIDENCE: IV.
