Abstract

Venovenous extracorporeal membrane oxygenation is increasingly being used to support patients with severe acute respiratory distress syndrome, but its cost-effectiveness is unknown. We assessed the cost-utility of venovenous extracorporeal membrane oxygenation for severe acute respiratory distress syndrome in adults compared with standard lung protective ventilation from the perspective of the healthcare system. We conducted a cost-utility analysis with a cohort state transition decision model using a lifetime time horizon, 1.5% discount rate, and outcomes reported as cost per quality-adjusted life year. Literature reviews were conducted to inform the model variables. Deterministic and probabilistic sensitivity analyses were conducted to assess uncertainty in the model. Canadian publicly funded healthcare system. Hypothetical cohort of adults with severe acute respiratory distress syndrome. Venovenous extracorporeal membrane oxygenation or standard lung protective ventilation. In our model, the use of venovenous extracorporeal membrane oxygenation compared with lung protective ventilation resulted in a gain of 5.2 life years and 4.05 quality-adjusted life years, at an additional lifetime cost of $145,697 Canadian dollars. The incremental cost-effectiveness ratio was $36,001/quality-adjusted life year. Sensitivity analyses show that the incremental cost-effectiveness ratio is sensitive to the efficacy of extracorporeal membrane oxygenation therapy and costs. Based on current data, venovenous extracorporeal membrane oxygenation is cost-effective for patients with severe acute respiratory distress syndrome. Additional evidence on the efficacy of venovenous extracorporeal membrane oxygenation for acute respiratory distress syndrome and in different subgroups of patients will allow for greater certainty in its cost-effectiveness.
