Existing research on postabortion emergency room visits is sparse and limited by methods which underestimate the incidence of adverse events following abortion. Postabortion emergency room (ER) use since Food and Drug Administration approval of chemical abortion in 2000 can identify trends in the relative morbidity burden of chemical versus surgical procedures.

The prevalence of induced abortion among women with children has been estimated indirectly by projections derived from survey research. However, an empirically derived, population-based conclusion on this question is absent from the published literature.

The number of pregnancies and interval between pregnancies can have significant impact on a woman’s reproductive, psychological, and general health. Exposure to multiple reproductive losses is especially associated with higher rates of negative outcomes.

Although a majority of women who have an abortion report having 1 or more children, there is no published research on the number of abortions which occur between live births, after a first child but before the last. The objectives of this research, therefore, were to estimate the period prevalence of an induced abortion separating live births in a population of Medicaid eligible enrollees and to identify the characteristics of enrollees significantly associated with the use of abortion to enable child spacing.

Pregnancy loss, natural or induced, is linked to higher rates of mental health problems, but little is known about its effects during the postpartum period. This study identifies the percentages of women receiving at least one postpartum psychiatric treatment (PPT), defined as any psychiatric treatment (ICD-9 290-316) within six months of their first live birth, relative to their history of pregnancy loss, history of prior mental health treatments, age, and race.

The objective of this study was to describe the characteristic patterns of subsequent pregnancy outcomes evolving from each of three initiating outcome events (birth, induced abortion, natural fetal loss) occurring in a Medicaid population fully insured for all reproductive health services.

The current measuring metric and reporting methods for assessing maternal mortality are seriously flawed. Evidence-based prevention strategies require consistently reported surveillance data and validated measurement metrics.
