^aThe mean monthly death rates for critical congenital heart disease and other/unspecified congenital heart disease were calculated by dividing total numbers of deaths of each type by total number of births and total number of state-months. These are not necessarily identical to the ratio of the mean number of monthly deaths and the mean number of monthly births. State-month periods with either voluntary screening policies enacted or mandatory screening policies that had been enacted but not yet implemented are included in the columns of nonmandatory policy states.

^bObservations are from all 50 states and the District of Columbia.

^cDefined as deaths that occurred 24 hours to less than 6 months after birth.

^dAlabama had a nonmandatory policy but enacted a mandatory policy that was not implemented by June 1, 2013.
