Cost-effectiveness of solvent/detergent-treated fresh-frozen plasma.
OBJECTIVE
Although transfusion-transmitted infections are rare, non-infectious complications occur relatively frequently. Solvent/detergent-treated fresh-frozen plasma (SD-FFP) has been shown to reduce the frequency of both types of complication, although previous economic evaluations failed to consider non-infective events and subsequently underestimated the benefits of SD-FFP.


METHODS
A time-series analytical model was used to estimate the incremental cost/life year saved for SD-FFP compared with untreated FFP, having controlled for post-transfusion mortality and patient age. Various infective and non-infective transfusion-related complications were considered.


RESULTS
The discounted cost/life year saved for SD-FFP use in the UK was pound sterling 22,728 [95% confidence interval (95% CI): pound sterling 22,604-22,853] for neonates and pound sterling 98,465 (95% CI: pound sterling 97,924-99,005) for patients aged 70. The cost-effectiveness ratio was below pound sterling 50,000/life year saved for patients < or = 48 years of age, and below pound sterling 30,000/life year saved for those < or = 21 years of age. In transfusion recipients with no significant morbidity, the cost-effectiveness ratio was pound sterling 12,335 for neonates and pound sterling 61,692 for 70-year olds. The most important driver of cost-effectiveness was transfusion-related acute lung injury (TRALI), on account of its relatively high incidence and mortality rate.


CONCLUSIONS
Previous analyses greatly underestimated the cost-effectiveness of SD-FFP. Inclusion of non-infectious complications suggests that SD-FFP is cost-effective in patients < or = 48 years of age and in older patients with good clinical prognosis, which may justify the wider use of this technology.
