title: Residence, delivery and referral patterns of infants and fetuses with birth defects delivered in Hawaii, 1986-1999.
abstract: Information on residence, delivery and referral patterns is useful to a birth defects program for allocation of resources, predicting where deliveries may have occurred, and estimating the impact of altering geographic inclusion criteria. The purpose of this study was to describe the residence, delivery and referral patterns for infants and fetuses with birth defects delivered in Hawaii. Data were obtained from the Hawaii Birth Defects Program and included birth defects cases delivered between 1986 and 1999 with known delivery residence and place of delivery. Of 12,873 total cases, 171 (1%) were delivered to out-of-state residents. Of the remaining 12,702 cases delivered to residents in the four Counties of Hawaii, 9905 (78%) were to City and County of Honolulu residents and 2797 (22%) were to residents of Hawaii, Kauai and Maui Counties. Of the cases delivered to City and County of Honolulu residents, 9903 were delivered in that County. Of the cases delivered to residents of the other three Counties, 591 (21%) were referred to the City and County of Honolulu for delivery, and 1602 (57%) were referred to the City and County of Honolulu for any reason. Honolulu delivery referral rates and total referral rates for cases delivered to Hawaii, Kauai and Maui County residents were higher with prenatal diagnosis of a birth defect (59 and 87%, respectively) and elective termination (70 and 85%, respectively), and varied among 53 different types of birth defect (0-83% and 23-100%, respectively).
