Summary: Administering zoledronic acid (ZA) to older hip fracture patients during the hospital stay has faced safety concerns. However, in this study of 161 patients, no ZA-related side effects or readmissions were observed, demonstrating that ZA administration during hospitalization is safe and effective for secondary fracture prevention. Purpose: According to the 2022 Dutch 'Osteoporosis and fracture prevention' guideline, zoledronic acid (ZA) is the preferred osteoporosis treatment for hip fracture patients. Less than 25% of hip fracture patients visit the outpatient fracture liaison service, therefore inpatient administration of ZA during the hip fracture hospitalization is now recommended in patients > 75 years. In the OLVG Hospital, inpatient administration of ZA during hospitalization for hip fracture in older patients has been standard of care since 2020. Methods: This single center retrospective observational follow-up study included hip fracture patients > 75 years admitted to the orthogeriatric ward of the OLVG Hospital, and treated with 5 mg of ZA intravenously on the day of hospital discharge between June 2020 and December 2022. Life expectancy estimated < 12 months, creatinine clearance < 35 ml/min, hypocalcemia, and high risk of osteonecrosis of the jaw were contra-indications. During three months of follow-up (FU) adverse events, emergency room visits, hospital readmissions, and death were recorded. Results: In 161 consecutive hospitalized hip fracture patients (mean age 86 ± 6 years, 65% female, 18% nursing home) ZA was administered and no adverse events were recorded. During 3 months of FU, 8 patients (5%) visited the emergency room, 19 patients (12%) were re-admitted to the hospital, 3 with a new fracture (2 contralateral hip, 1 radius), and 17 patients (11%) died of reasons unrelated to ZA. Conclusion: This study shows that inpatient administration of zoledronic acid during hip fracture hospitalization is safe and feasible to prevent future fragility fractures in older hip fracture patients.
