Post-fracture care gap: a retrospective population-based analysis of Hong Kong from 2009 to 2012

Abstract

Patients who sustain an osteoporotic fracture are at increased risk of sustaining further osteoporotic fracture. The risk can be reduced by prescription of anti-osteoporosis medication. The aim of the present study was to determine the current practice in Hong Kong regarding secondary drug prevention of fragility fractures after osteoporotic hip fracture. Dispensation of anti-osteoporosis medication records from patients with new fragility hip fractures aged ≥65 years were retrieved using the Hospital Authority Clinical Data Analysis and Reporting System from 2009 to 2012. The intervention rate each year was determined from the percentage of patients receiving anti-osteoporosis medication within 1 year after hip fracture. A total of 15 866 patients with osteoporotic hip fracture who met the criteria were included. The intervention rate differed each year from 2009 to 2012, ranging between 9% and 15%. Orthopaedic surgeons initiated 63% of anti-osteoporosis medication, whereas physicians initiated 37%. The anti-osteoporosis drugs being prescribed included alendronic acid (76%), ibandronic acid (12%), strontium ranelate (5%), and zoledronic acid (4%). Most patients with hip fracture remained untreated for 1 year after the osteoporotic hip fracture. The Hospital Authority should allocate more resources to implement a best practice framework for treatment of patients with hip fracture at high risk of secondary fracture.
