Clinical and economic analysis of macrocyclic gadolinium-based compounds for use in magnetic resonance imaging diagnostics

Abstract

Gadolinium-based contrast compounds are paramagnetic chemicals that allow enhancing contrast during magnetic resonance imaging (MRI) tomographic investigation. It`s known that linear gadolinium-based paramagnetic compounds cause permanent accumulation of gadolinium in tissues. This effect is less pronounced in macrocyclic gadolinium-based compounds, which makes them increasingly relevant.Aim. Evaluate clinical and economic analysis of macrocyclic gadolinium-based contrast gadoteridol compared with gadobutrol for MRI diagnostics.Methodology. Decision tree model with one-year time horizon was constructed. Model accounted for specific parameters of administration of each of compared contrasts. Only direct medical costs evaluated. The number of detected anomalies selected as effectiveness criterion. We used cost minimization analysis (CMA) because there were no differences in effectiveness. Then we performed the budget impact analysis (BIA), accounting to number of patients receiving MRI of brain in the Russian Federation. Relevant sensitivity analyses carried out.Result. Gadoteridol was superior both in CMA (cost reduction reached 21.51 %) and BIA (budget burden reduced by 10.31 % which amounts to 15 735 332 rubles). Sensitivity analysis confirms the model robustness.Conclusion. Clinical and economic analysis of gadoteridol compared with gadobutrol demonstrated that expansion of gadoteridol use in Russian healthcare is economically feasible.
