Number of previous pregnancies

Guide for use:

In multiple pregnancies with more than one type of outcome, the pregnancies should be recorded in the following order:

• all live births
• stillbirth
• spontaneous abortion
• induced abortion
• ectopic pregnancy

A pregnancy resulting in multiple births should be counted as one pregnancy.

Where the outcome was one stillbirth and one live birth, count as stillbirth.

If a previous pregnancy was a hydatidiform mole, code as spontaneous or induced abortion (or rarely, ectopic pregnancy), depending on the outcome.

Perinatal statistics:

The number of previous pregnancies is an important component of the woman's reproductive history. Parity may be a risk factor for adverse maternal and perinatal outcomes.
