GENERAL INFORMATION

  • A stillbirth is defined as a product of conception weighing 500 grams or more or of 20 or more weeks gestation which, after being completely delivered, shows no sign of life. Therapeutic abortions that meet either criterion are also classified as stillbirths in Ontario.

METHODS

Data Collection Methods

  • Information on stillbirths is collected by the Office of the Registrar General and is based on three forms: 1) the Statement of Stillbirth completed by parents, 2) the Physician Notice of Birth or Stillbirth (PNOB) completed by the physician, and 3) the more detailed Medical Certificate of Stillbirth completed by the physician.

Analysis Methods

  • Data are analyzed by the residence of the mother, not by where the stillbirth occurred.
  • Out-of-province stillbirths occurring to Ontario women have been excluded from analyses.
  • Due to changes in registration practices of stillbirths within the lowest birth weight categories, both crude stillbirth rates and birth weight-specific rates should be reported.
  • Rates and proportions based on counts less than five (5) must be suppressed.

LIMITATIONS

  • Because of data quality concerns, 1991 and 1992 data are not presented
  • There are possible errors in the stillbirth data file related to assignment of municipality of residence/census subdivision of mother. The Central East Health Information Partnership (CEHIP) completed a report on this issue for the live birth file in July, 2000. For more information see CEHIP's Data Quality Report: Effect of Residence Code Errors on Fertility Rates
