Introduction:

Venoarterial extracorporeal life support (ECLS) is increasingly used in patients during cardiogenic shock, due to favorable results in this very high-risk scenario. However, it is a costly intervention that requires heavy financial investment and specialized human resources.

Methods:

Cost-effectiveness analysis to evaluate ECLS in the perspective of the Brazilian public health system (SUS) in the population of adult patients with cardiogenic shock. A decision tree comparing ECLS and usual care was built, using efficacy data from a systematic review of literature, and cost data from SUS reimbursement values. Impact of parameter variability and uncertainty were ascertained with deterministic and probabilistic sensitivity analysis.

Results:

Usual care resulted in thirty percent probability of survival, at an average cost of 3,000 international dollars (Int$/USD); the strategy that includes ECLS resulted in sixty-two percent survival rate, and average cost of Int$ 23,000, with incremental cost-effectiveness ratio (ICER) of Int$ 62.215 per averted in-hospital death. Results were sensitive to device cost, and survival difference between strategies. In probabilistic sensitivity analysis, ECLS was consistently more costly and more effective than usual care; based on a willingness-to-pay of three times Brazilian gross domestic product (GDP) per capita (Int$ 45,000), there was twenty-seven percent probability of ECLS being cost-effective.

Conclusions:

ECLS has the potential to increase survival for cardiogenic shock, but would significantly increase costs. In the Brazilian public health system, the cost per averted in-hospital death is 4.1 times the domestic GDP per capita.
