RESUMO

PURPOSE: To study the prevalence of osteoporosis, falls and fractures in adults with ischaemic stroke. METHODS: Observational cohort study of adults aged ≥ 50 years admitted with ischaemic stroke over a 12-month period were invited to participate in a telephone interview one-year post-stroke to ascertain falls and fracture. A Fracture Risk After Ischaemic Stroke (FRAC-stroke) score was calculated. RESULTS: Of the 1267 patients admitted to the stroke unit between 1 January 2020 and 31 December 2020, 624 had a modified Rankin Score documented. Of these, 316 adults ≥ 50 years had ischaemic stroke and 131 consented to a telephone interview. Mean age was 72.4 ± 10.7 years and 36.6% were female. 34 patients (25.9%) had a FRAC-stroke score of ≥ 15, equating to ≥ 5% risk of fracture in the year following stroke. Eleven (8.4%) patients (6 female) had a minimal trauma fracture in the 12 months post-stroke. There was a significant difference in patients experiencing falls pre- and post-stroke (19.8% vs 31.3%, p = 0.04). FRAC-stroke score was higher in those who had a fracture post stroke compared those who did not (20.4 vs 8.9, p < 0.001). Receiver operating characteristic analysis found an area under the curve of 0.867 for FRAC-stroke score (95% CI 0.785-0.949, p < 0.005). The optimal cutoff value for FRAC-stroke score predicting fracture was 12 with a sensitivity of 90.9% and specificity of 70%. CONCLUSION: The FRAC-stroke score is a simple clinical tool that can be used to identify patients at high risk of fracture post-stroke who would most benefit from osteoporosis therapy. Stroke is a risk factor for fracture due to immobilisation, vitamin D deficiency and increased falls risk. This study found that a simple bedside tool, the FRAC-stroke score, can predict fracture after ischaemic stroke. This will allow clinicians to plan treatment of osteoporosis prior to discharge from a stroke unit.
