BACKGROUND: Patients with distributive shock who are unresponsive to traditional vasopressors are commonly considered to have severe distributive shock and are at high mortality risk. Here, we assess the cost-effectiveness of adding angiotensin II to the standard of care (SOC) for severe distributive shock in the US critical care setting from a US payer perspective.
METHODS: Short-term mortality outcomes were based on 28-day survival rates from the ATHOS-3 study. Long-term outcomes were extrapolated to lifetime survival using individually estimated life expectancies for survivors. Resource use and adverse event costs were drawn from the published literature. Health outcomes evaluated were lives saved, life-years gained, and quality-adjusted life-years (QALYs) gained using utility estimates for the US adult population weighted for sepsis mortality. Deterministic and probabilistic sensitivity analyses assessed uncertainty around results. We analyzed patients with severe distributive shock from the ATHOS-3 clinical trial.
RESULTS: The addition of angiotensin II to the SOC saved .08 lives at Day 28 compared to SOC alone. The cost per life saved was estimated to be $108,884. The addition of angiotensin II to the SOC was projected to result in a gain of .96 life-years and .66 QALYs. This resulted in an incremental cost-effectiveness ratio of $12,843 per QALY. The probability of angiotensin II being cost-effective at a threshold of $50,000 per QALY was 86 percent.
CONCLUSIONS: For treatment of severe distributive shock, angiotensin II is cost-effective at acceptable thresholds.
