Acknowledgment: The authors thank Prof. Margaret Brandeau for her feedback and the team at The Ottawa Hospital (Dr. Kumanan Wilson, Dr. Malia Murphy, and JoAnn Colas), who provided unpublished data on the proportion of transfusion recipients who are pregnant women not yet arrived at the hospital for delivery. The authors also thank Roche and Grifols for providing data from their Investigational New Drug Applications, which were used to estimate the rate of ZIKV-positive donations for Puerto Rico and the 50 states.
Financial Support: Mr. Russell was funded as an intern and contractor by Vitalant Research Institute. No external funding was received.
Disclosures: Mr. Russell reports personal fees from Terumo BCT outside the submitted work. Dr. Stramer reports laboratory support from Grifols, Roche Diagnostics, and Abbott Laboratories and speaker fees from Roche Diagnostics and Cerus outside the submitted work. Dr. Busch reports research grants related to ZIKV from Grifols, funding to his laboratory at Vitalant Research Institute from Grifols and Roche to perform confirmatory testing for ZIKV supporting the Zika testing investigational new drugs, and funding to his laboratory from Cerus for a study of ZIKV inactivation red blood cell transfusions, all outside the submitted work. Dr. Custer reports grants from Grifols Diagnostic Solutions, Terumo BCT, Macopharma, and Cerus and personal fees from Terumo BCT outside the submitted work.

In 2016, universal individual donation nucleic acid testing (ID-NAT) of donated blood for Zika virus began in U.S. states and territories.
To assess the cost-effectiveness of universal ID-NAT in the first year of screening compared with alternatives for the 50 states and separately for Puerto Rico.
Microsimulation that captured Zika-related harms to transfusion recipients, sexual partners, and their infants.
National testing results compiled by AABB and costs, utilities, and outcome probabilities estimated from the literature.
Universal ID-NAT, universal mini-pool NAT (MP-NAT), and ID-NAT exclusively for components transfused to women of childbearing age. Seasonally targeted strategies in Puerto Rico and geographically targeted strategies in the 50 states were also considered.
Costs, quality-adjusted life-years (QALYs), and outcomes.
In Puerto Rico, MP-NAT exclusively during high mosquito season was cost-effective at $81 123 per QALY (95% CI, −$49 138 to $978 242 per QALY). No screening policy was cost-effective in the 50 states. Universal ID-NAT cost $341 million per QALY (CI, $125 million to $2.90 billion per QALY) compared with no screening in the 50 states.
In Puerto Rico, MP-NAT only during the season of high mosquito activity was most cost-effective in 64% of probabilistic sensitivity analysis iterations. In the 50 states, no intervention was cost-effective in 99.99% of iterations. Cost-effectiveness was highly dependent on the rate of assumed infectious donations.
Data were limited on the component-specific transmissibility of Zika and long-term sequelae of infection.
Screening was cost-effective only in the high mosquito season in Puerto Rico, and no evaluated screening policy was cost-effective in the 50 states. During periods with lower rates of Zika-infectious donations, the cost-effectiveness of screening will be even less favorable.
