Another measure of mortality relative to pregnancy is pregnancy-related deaths which, as defined by the CDC, extends the period of consideration to include up to 1 year within the end of a pregnancy regardless of the outcome. Pregnancy associated death, as defined by the American College of Obstetricians and Gynecologist (ACOG) as all deaths within one year of a pregnancy outcome, without consideration of any causal effect. Identification of pregnancy associated deaths is a precursor for investigations into whether or not the pregnancy was a direct or indirect contributing cause of the death.
