Using a data set of newborn screening specimens tested by the New England Newborn Screening Program (NENSP) between January 1999 and February 2003, we analyzed the number of infants with positive newborn screening results and determined how many positive screening results were due to a recent multiplex expansion of services in some of the states. We found that for the subset of the 4-year cohort for which there was a 233% increase in the number of disorders screened (from 9 to 30 disorders), there was a 31% increase in the number of affected infants identified by the screen. We project that if all states in the program expanded their services and if the incidence of disorders is similar across states, there would be an observed 45% increase in the number of infants detected by the screen and a 43% increase in the number of infants for whom the screening algorithm would require some contact with the infants' health care provider. Furthermore, of those requiring contact, we project a 300% increase in the number of screened-positive infants who would be referred to tertiary care centers for a diagnostic evaluation. Increased contact with the medical community from additions to newborn screening as demonstrated in this report emphasizes the need for an approach in which the newborn screening program assures coordinated communications between birth units, laboratory, primary health care providers, and specialists.
