Abstract

Objective

Congenital cytomegalovirus infection (cCMV) can cause symptoms at birth as well as long-term impairment. This study estimates cCMV-related healthcare costs in the Netherlands in early childhood.

Design, setting and patients

In a nationwide retrospective cohort study, 156 children with cCMV were identified by testing 31 484 neonatal dried blood spots for cCMV. Use of healthcare resources in the first 6 years of life by children with cCMV and a matched cCMV-negative control group were analysed. Mean costs per child were calculated by multiplying healthcare resource use by its reference prices.

Exposure

Children with cCMV were compared with cCMV-negative children.

Main outcome measures

The average total healthcare costs per child were based on the average costs for hospital admissions and consultations by healthcare providers.

Results

Mean healthcare costs of children with cCMV (€6113, n=133) were higher than children without cCMV (€3570, n=274), although statistically not significant, with a mean difference of €2544 (95% CI €-451 to €5538). The costs of children with long-term impairment were two times higher in children with cCMV (€17 205) compared with children without cCMV (€8332).

Conclusions

Children with cCMV, especially those with long-term impairment and those symptomatic at birth, accrue higher healthcare costs than cCMV-negative children in the first 6 years of life, although this is not statistically significant. This economic impact is of importance in the evaluation of preventive measures against cCMV.
