Cost-Effectiveness of Mobile versus Fixed Computed Tomography and Magnetic Resonance Imaging: A Systematic Review and Economic Evaluation
Background: Mobile technologies are widely used in healthcare. The purpose of this study was to compare the effectiveness and cost-effectiveness of fixed computed tomography (CT) and magnetic resonance imaging (MRI) with the mobile ones.
Methods: In this systematic review, PubMed, Cochrane Library, Scopus and CRD database were searched from 1995 to 2015. The data on safety and effectiveness of technologies were extracted from included studies. Because the review showed no significant differences in the performance of mobile CT and MRI compared to the fixed ones, then a cost minimization approach was used to explore the cost-effectiveness of three scenarios.
Results: Twenty two articles were included in the review that showed no statistically significant differences in the performance of mobile MRI and CT scan compared to the fixed ones. The cost minimization approach showed that the third scenario based on purchasing a common mobile MRI and CT scan; and using it by two or more hospitals that are in rational distance from each other is associated with the lowest costs, so it is the most cost-effectiveness strategy.
Conclusion: The performance of Mobile CT and mobile MRI is comparable to the fixed ones; and using a combined mobile CT and MRI by two or three hospitals is the most cost-effective approach.
