Objectives. To assess the sensitivity and specificity of self-reported osteoporosis compared with dual energy X-ray absorptiometry (DXA) defined osteoporosis, and to describe medication use among participants with the condition. Methods. Data were obtained from a population-based longitudinal study and assessed for the prevalence of osteoporosis, falls, fractures and medication use. DXA scans were also undertaken. Results. Overall 3.8% (95% confidence interval (CI) 3.2 to 4.5) of respondents and 8.8% (95% CI 7.5 to 10.3) of those aged ≥ 50 years reported that they had been diagnosed with osteoporosis by a doctor. The sensitivity (those self-reporting osteoporosis and having low bone mineral density (BMD) on DXA) was low (22.7%), although the specificity was high (94.4%). Only 16.1% of those aged ≥ 50 years and with DXA-defined osteoporosis were taking bisphosphonates. Conclusions. The sensitivity of self-reporting to identify osteoporosis is low. Anti-osteoporotic medications are an important part of osteoporosis treatment but opportunities to use appropriate medications were missed and inappropriate medications were used

Introduction. With an ageing population comes an increased prevalence of osteoporosis and associated fracture. Whilst treatment of the condition following such a fracture is partially effective, primary prevention through screening and appropriate follow-up is the ideal. In order to assess a population's risk of fracture, paper questionnaires would traditionally have to be sent, however this is an wasteful and costly. A more efficient method may be to have patients assess their own FRAX score through a modified computer application. Aim. To investigate the feasibility of patients self-reporting their FRAX score from the use of a touch screen application. Methods. A patient-friendly application based on the FRAX questionnaire was developed for use on iPad. This was then trialled on inpatients and outpatients at the RNOH, Stanmore and at 2 GP's surgeries. A paper questionnaire then was used to assess ease of use of the application. Results. 314 patients completed the iPad application with 68 patients over 55 completing the paper questionnaire. The mean useability score was 2.6 (1-easy, 10-hard). 75% of respondents preferred using a touch screen application than paper or phone surveys and 83% stated they would use the touch screen if it was offered in GP surgeries. Discussion and Conclusion. Touch screen applications are readily used to self-report fracture risk by the majority of the over 55 population. Applications such as these have the potential to collect large amounts of data quickly and cheaply, as well as engaging patients in becoming aware of the risks of osteoporosis
