| Abstract: | Congenital cytomegalovirus infection is the most common congenital infection. Using a decision tree model, cost-effectiveness of maternal screening with subsequent prenatal valacyclovir treatment and newborn screening with neonatal valganciclovir treatment was evaluated. The incremental cost-effectiveness ratio (ICER) was calculated for (1) universal maternal antibody screening with prenatal valacyclovir treatment compared to targeted newborn screening, and (2) universal newborn screening with postnatal valganciclovir treatment compared to targeted newborn screening. We performed a one-way sensitivity analysis. Compared to targeted newborn screening, the ICERs for universal newborn screening and maternal screening were 2 966 296 Japanese Yen (JPY) (21 188 USD) and 1 026 984 JPY (7336 USD), respectively. In all scenarios in the one-way sensitivity analysis, the ICERs of the maternal screening and the universal newborn screening strategies were less than three gross domestic product per capita compared with the targeted newborn screening strategy. Both maternal and universal newborn screening strategies may be cost-effective than a targeted newborn screening program. The potential utility of the maternal screening with valacyclovir treatment strategy, while potentially cost effective in regions with lower baseline seroprevalence rates, requires further study as the modeling was based on limited evidence. |
