European heart journal. Quality of care & clinical outcomes(2023)
摘要
Aims To estimate the cost-effectiveness and cost-utility ratios of a restrictive vs. liberal transfusion strategy in acute myocardial infarction (AMI) patients with anaemia. Methods and results Patients (n = 666) with AMI and haemoglobin between 7-8 and 10 g/dL recruited in 35 hospitals in France and Spain were randomly assigned to a restrictive (n = 342) or a liberal (n = 324) transfusion strategy with 1-year prospective collection of resource utilization and quality of life using the EQ5D3L questionnaire. The economic evaluation was based on 648 patients from the per-protocol population. The outcomes were 30-day and 1-year cost-effectiveness, with major adverse cardiovascular events (MACEs) averted as the effectiveness outcome. and a 1-year cost-utility ratio. The 30-day incremental cost-effectiveness ratio was euro33 065 saved per additional MACE averted with the restrictive vs. liberal strategy, with an 84% probability for the restrictive strategy to be cost-saving and MACE-reducing (i.e. dominant). At 1 year, the point estimate of the cost-utility ratio was euro191 500 saved per quality-adjusted life year gained; however, the cumulated MACE was outside the pre-specified non-inferiority margin, resulting in a decremental cost-effectiveness ratio with a point estimate of euro72 000 saved per additional MACE with the restrictive strategy. Conclusion In patients with AMI and anaemia, the restrictive transfusion strategy was dominant (cost-saving and outcome-improving) at 30 days. At 1 year, the restrictive strategy remained cost-saving, but clinical non-inferiority on MACE was no longer maintained. One sentence summary The use of a restrictive transfusion strategy in patients with acute myocardial infarction is associated with lower healthcare costs, but more evidence is needed to ascertain its long-term clinical impact.
