Washington State hospitals were queried about the fate of 507 infants born in 1978-79 for whom no linked death certificate existed. Only ten previously unregistered deaths were discovered, raising mortality for this group by 2.5 per cent. In addition, 13 previously unmatched death records were linked to birth records, providing more accurate calculation of birthweight-specific mortality rates. Washington State infant death registration is more complete that that found in either Georgia or North Carolina.
华盛顿州的医院被问及1978年至1979年出生的507名婴儿的情况，这些婴儿没有与之关联的死亡证明。仅发现了10例此前未登记的死亡病例，这使得该群体的死亡率提高了2.5%。此外，13例此前未匹配的死亡记录与出生记录相关联，从而更准确地计算了按出生体重划分的死亡率。华盛顿州的婴儿死亡登记比佐治亚州或北卡罗来纳州更为完整。
