A public health investigation in Nashville, Tennessee, is aimed at learning why some parents don’t want their newborns to receive a vitamin K injection, which is given routinely to prevent coagulopathy.
The investigation was spurred by 4 cases of late vitamin K deficiency bleeding (VKDB) reported between February and September 2013. Vitamin K deficiency bleeding is classified as early, developing within 24 hours of birth; classic, which occurs between 24 hours and 7 days of life; or late, which develops in infants aged 2 to 24 weeks. Because only a limited amount of vitamin K crosses the placenta, infants are predisposed to develop VKDB.
