ObjectiveThe aim of our study was to describe risk factors for legal abortion mortality and the characteristics of women who died of legal abortion complications for the period 1972 through 1987.Study DesignWe reviewed abortion mortality surveillance data collected by the Division of Reproductive Health, Centers for Disease Control and Prevention, and calculated rates by various demographic and reproductive health variables using the Center for Disease Control and Prevention's abortion surveillance data as denominators. Rates are reported as legal abortion deaths per 100,000 abortions.ResultsBetween 1972 and 1987, 240 women died as a result of legal induced abortions. The case-fatality rate decreased 90% over time, from 4.1 deaths per 100,000 abortions in 1972 to 0.4 in 1987. Women > or = 40 years old had three times the risk of death as teenagers (relative risk 3.0, 95% confidence interval 1.5 to 6.0), and black women and those of other minority races had 2.5 times the risk of white women (relative risk 2.5, 95% confidence interval 1.9 to 3.2). Abortions at > or = 16 weeks were associated with a risk of death almost 15 times the risk of death from procedures at < or = 12 weeks' gestation. Women undergoing currettage procedures for abortion had a significantly lower risk of death than women undergoing other procedures. Whereas before 1977 infection and hemorrhage were the leading causes of death, during 1977 through 1982 anesthesia complications emerged as one of the leading causes of death and since 1983 have become the most frequent cause.ConclusionsAlthough legal induced abortion-related deaths are rare events, our findings suggest that more rigorous efforts are needed to increase the safety of anesthetic methods and anesthetic agents used for abortions and that efforts are still necessary to monitor serious complications of abortion aimed at further reducing risks of death associated with the procedure.
