Abortion mortality, United States, 1972 through 1987

Area of Science:

• Reproductive Health
• Public Health Surveillance
• Medical Safety

Background:

• Legal induced abortion is a common reproductive health procedure.
• Understanding mortality risk factors is crucial for improving patient safety.
• Historical data provides insights into trends and evolving complications.

Purpose of the Study:

• To identify risk factors associated with legal abortion mortality.
• To characterize women who died from legal abortion complications between 1972 and 1987.
• To analyze trends in abortion-related deaths and their causes over time.

Main Methods:

• Review of abortion mortality surveillance data from the Centers for Disease Control and Prevention (CDC).
• Calculation of mortality rates based on demographic and reproductive health variables.
• Analysis of leading causes of death and their temporal changes.

Main Results:

• A 90% decrease in the legal abortion case-fatality rate from 1972 (4.1/100,000) to 1987 (0.4/100,000).
• Increased mortality risk observed for women aged 40+, minority races, and those undergoing abortions at or after 16 weeks gestation.
• Anesthesia complications emerged as a leading cause of death since 1983, replacing earlier causes like infection and hemorrhage.

Conclusions:

• Legal abortion-related deaths are rare but require continued monitoring and safety efforts.
• Enhancing the safety of anesthetic methods and agents used in abortions is critical.
• Ongoing surveillance is necessary to further reduce the risks associated with abortion procedures.
