Erratum

PMCID: PMC1288345

In the October 1998 issue of the Journal, there were two table errors in the article “Prenatal Screening for Cystic Fibrosis Carriers: An Economic Evaluation,” by Rowley et al. (63:1160–1174). In the last row of table 5, the difference in the marginal cost per QALY should be “$8,290.” Also, table 9, which compares the marginal cost per QALY for selected preventive measures, may be misleading, since the authors of the references cited used two different methods of calculation. The values for antepartum Rh immunization, T4 thyroid screening, phenylketonuria screening, and school tuberculin screening were derived simply by dividing the program costs incurred by the number of those not screened. This latter methodology is the preferred method, since it makes a comparison, often with existing practice; however, since it often entails high costs for the unscreened group, it may yield a cost-effectiveness ratio that is more favorable to screening. The Journal regrets these errors.
