Background and objectives

Osteoporosis and dementia are common and associated with a high healthcare burden. The aim of this paper was to assess the impact of dementia on treatment, morbidity and mortality in osteoporosis.


Data were collected on 502 prospective orthogeriatric admissions for fracture. Fisher's exact chi-square was used to compare treatment stratified by dementia status.


Of the 502 patients, 281 (56%) had osteoporosis, 226 (45%) had dementia, and 156 (31%) had dementia and osteoporosis diagnosed before they sustained fractures. Patients with dementia were more likely to have osteoporosis but less likely to be receiving treatment. Although there was a significant improvement in discharge versus admission rates of osteoporosis treatment, those with dementia were less likely to be treated with antiresorptive therapy (36%, compared with 59%, P <0.001) or combined therapy (32%, compared with 56%, P <0.001) and had double the 90-day mortality (17.3%, compared with 9.6%) and six times the 30-day mortality (6.4%, compared with 1.6%).


Patients with dementia and osteoporosis have a higher risk of recurrent fractures and mortality. Prevention may be the key strategy.
