Background: Fragility fractures in older adults are associated with high risk of refracture and mortality. Despite guideline recommendations, inpatient bone-density assessment (DEXA) is often underutilised. DEXA T- score constitutes one of the necessary eligibility criteria for PBS reimbursement of osteoanabolic therapy in Australia. Registry data suggest fewer than 1 in 5 patients receive post-fracture DEXA or pharmacotherapy [1,2]. This study aimed to evaluate determinants and rates of inpatient DEXA in older patients with fractures.

Methods: Retrospective analysis of consecutive patients 65 years admitted with index fragility fracture to a secondary Orthopaedic Geriatrics Unit between January and April 2025. High imminent fracture risk was defined by hip or symptomatic vertebral fracture. Very High Risk was defined per Healthy Bones Australia[3]. Frailty was defined by Clinical Frailty Score 6.

Results: Eighty patients were included with median age 83.5 years (IQR 78.5 to 88.5), with 51 females (63.7%). Eighteen (22.5%) patients were considered frail, and 14 (17.5%) were nursing home residents. Of fifty-five patients with high imminent fracture risk, 16 (29.1%) were considered appropriate candidates for DEXA; with 3 (18.8%) receiving DEXA. Of patients considered not of high risk, 6 (24%) were assessed by DEXA, leading to significant difference in DEXA uptake by risk profile (p=0.023). In combined High or Very High risk criteria, 6 (37.5%) eligible patients received DEXA analysis. Overall, 71 of 80 (88.7%) patients did not undergo DEXA imaging, reflecting missed opportunities in eligible patients, limitations imposed by clinical frailty or residential status, and appropriate non-investigation of a low-risk population.

Conclusions: Inpatient DEXA is underutilised in older adults with fragility fractures. Although frailty and nursing home residency limit suitability for some patients, the majority of eligible high-risk patients did not undergo imaging. System level approaches, such as automatic referral or post-discharge liaison models, are needed to close the practice gap.
