This study aims to determine osteoporosis (OP) investigation and treatment within post-fracture initiatives conducted in fracture clinics and other orthopedic environments. A systematic review was conducted. Eligibility criteria were: hip fracture patients plus all other fracture patients presenting with a fragility fracture, orthopedic setting where orthopedic physicians/staff were involved, intervention to improve OP management, primary data on ≥20 patients from randomized controlled trials (RCTs) and other study designs. We calculated outcome data within 6 months of screening from an intention-to-treat principle to derive an equated proportion (EP) across interventions. Outcomes were: (1) proportion of patients investigated with bone densitometry, (2) proportion of patients initiating OP medication, and (3) proportion of patients taking OP medication. We identified 2,259 citations, of which 57 articles that included 64 intervention groups were eligible. The median EP for patients investigated was 43% and the 75th percentile was 71%. The median EP for medication initiation was 22% and the 75th percentile was 34%. The median EP for medication taking was 27.5% and the 75th percentile was 43%. The EPs for all outcomes were higher for interventions with dedicated personnel to implement the intervention and those within which bone mineral density testing and/or treatment were included. In studies with an EP, up to 71% of patients were investigated for OP, but <35% initiated medication, and <45% were taking medication within 6 months of screening. Calculating an EP allowed us to compare outcomes across the studies, therefore capturing both RCTs and other study designs typical of real-world settings.
