P45 Visualizing Joint Costs and Effects for Multiple Alternatives within Cost Effectiveness Analyses: Cost-Disutility Versus Traditional Cost-Effectiveness Planes in an Economic Evaluation of Opioid Use Disorder Treatments

Multiple options exist to visually present the joint costs and effects of multiple alternatives within a cost effectiveness analysis (CEA). The most common method to characterize treatment alternatives’ costs and effectiveness is the cost effectiveness plane. We present an application of an alternative presentation method introduced by Eckermann to plot alternatives’ costs and effectiveness: the cost disutility (C-DU) plane. We compare the C-DU visualization to the traditional cost effectiveness plane using a CEA on pharmacological treatments for opioid use disorder (OUD). Technical and economic efficiencies may also be calculated using the C-DU plane, quantifying divergence from optimality for suboptimal treatments.
