Maternal death or maternal mortality is defined by the World Health Organization (WHO) as "the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental causes."Adding to the WHO definition, the CDC extends the period of consideration to include up to 1 year within the end of a pregnancy regardless of the outcome.Two performance indicators used interchangeably are maternal mortality and maternal mortality ratio, both abbreviated as "MMR". By 2017, the world maternal mortality rate had declined 44% since 1990, but still every day 808 women die from pregnancy or childbirth related causes. [Source: Wikipedia
