Objective:
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.
Material And Methods:
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.
Results:
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.
Conclusions:
Using magnetic resonance in addition to conventional radiography in patients suffering from diabetic foot and signs of infection was cost-effective for Colombia.
