Are perinatal autopsy rates satisfactory?

Summary

Perinatal autopsy rates are higher than adult rates but consent remains a challenge. Clearer definitions are needed for accurate perinatal autopsy rate reporting.

Area of Science:

  • Perinatal Pathology
  • Medical Ethics
  • Public Health

Background:

  • Perinatal autopsies are crucial for understanding causes of death and improving obstetric care.
  • Existing data on perinatal autopsy rates and factors influencing consent are limited.
  • Accurate reporting requires clear definitions, especially for non-registrable deliveries.

Purpose of the Study:

  • To determine perinatal autopsy rates across different categories of perinatal death.
  • To investigate maternal and obstetric factors influencing consent for perinatal autopsies.

Main Methods:

  • Retrospective analysis of perinatal autopsy rates from 1990-1993 at a South Australian tertiary maternity hospital.
  • Categorization of perinatal deaths: termination for anomalies, fetal deaths/stillbirths, and neonatal/post-neonatal deaths.
  • Case-control study matching autopsied cases with non-autopsied cases to identify factors affecting consent.

Main Results:

  • High autopsy rates for terminations (92.4%) and intrauterine deaths (87.7%), higher for registrable births (>20 weeks gestation).
  • Overall autopsy rate for liveborn infants was 58.8%, with neonatal autopsy rate at 59.6%.
  • No significant associations found between consent and maternal factors (gravidity, parity, employment, insurance, marital status) or infant postnatal age.

Conclusions:

  • Perinatal autopsy rates exceed adult rates but fall below the recommended 75% for registrable births.
  • Parental consent is the primary limiting factor for achieving higher autopsy rates.
  • Standardized definitions for perinatal autopsies and their rates are necessary, particularly for non-registrable deliveries.
