Cost-effectiveness and effectiveness of applying intelligent osteoporosis health risk assessment system in community-dwelling women: a novel evidence-based study

Abstract

Background: Few studies have explored how to assist at risk females understand the status of osteoporosis without invasive data.Aims: To develop an intelligence osteoporosis health risk evaluation system and used for a preliminary empirical analysis of Asian women.Setting: This study is focused on community-dwelling women who had accepted dual-energy X-ray absorptiometry examination in health evaluation centre of a medical centre in north Taiwan from 2005–2006.Design: A longitudinal, evidence-based study was conducted.Method: The first stage is to establish the data base. This part included information from random samples (n = 220), including data for bone mineral density, osteoporosis risk factor, knowledge, belief and behaviour. The second stage is to detect the accuracy of this system including sensitivity, specificity, positive predictive value and negative predictive value. The third part is to evaluate the preliminary effect of nursing evidence-based study. Participants (n = 90) determined the relative risks of osteoporosis with system were randomly grouped into experimental or control group.Results: The content validity index among knowledge, beliefs and behaviours were 0·99, 0·89 and 0·95, respectively. In Cronbach’s alpha value, osteoporosis prevention knowledge belies and behaviours were 0·84, 0·79 and 0·77, respectively. The sensitivity and specificity of the analytical tools were 75%. In preliminary empirical study, this study showed the knowledge and perceived benefits of osteoporosis could be promoted by individual nursing instruction and could obtain economical and effective results.Conclusions: This study can be applied in different diseases health risk evaluation in the future and provides community residents a good reliability, good validity, practical, convenient and economic self-health management model.Relevance to clinical practice: This study developed a useful approach for providing Asia women with a reliable, valid, convenient and economical self-health management model to increase the effectiveness of osteoporosis prevention programs for at risk women.
