Collection and usage attributes

Guide for use:Help on this term

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

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

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.

Comments:Help on this term

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.

A previous history of spontaneous abortion identifies the mother as high risk for subsequent pregnancies.
