Performing a cost-effectiveness analysis of adding magnetic resonance to conventional radiography in patients suffering from diabetic foot and signs of infection from the payer's point of view.
The cost effectiveness (from the payer's point of view) of conventional radiography plus magnetic resonance was calculated for patients having diabetic foot and signs of infection by means of a Markov model. Costs were measured in 2008 Colombian pesos and effectiveness in terms of disability adjusted life years (DALY). The cost-effectiveness threshold was the Colombian 2008 per capita GDP, $ 10,761,691.
Using magnetic resonance in addition to conventional radiography in this population had a $ 1,532,778 and $ 1,741,311 incremental cost-effectiveness ratio, without and with discount, respectively; the results were robust to sensitivity analysis.
Using magnetic resonance in addition to conventional radiography in patients suffering from diabetic foot and signs of infection was cost-effective for Colombia.
从支付方的角度，对糖尿病足且有感染迹象的患者在传统放射成像基础上增加磁共振成像进行成本效益分析。
通过马尔可夫模型计算糖尿病足且有感染迹象患者传统放射成像加磁共振成像的成本效益（从支付方角度）。成本以2008年哥伦比亚比索计量，效果以伤残调整生命年（DALY）衡量。成本效益阈值为2008年哥伦比亚人均国内生产总值，即10,761,691美元。
在该人群中，传统放射成像基础上使用磁共振成像，无贴现和有贴现时的增量成本效益比分别为1,532,778美元和1,741,311美元；结果对敏感性分析具有稳健性。
对哥伦比亚而言，糖尿病足且有感染迹象的患者在传统放射成像基础上使用磁共振成像具有成本效益。
