Self-managed abortion, when a person performs their own abortion without clinical supervision, is a model of abortion care used across a range of settings. To provide a comprehensive synthesis of the available literature on self-managed abortion, we conducted a systematic search for peer-reviewed research in April 2019 in PubMed, Embase, Web of Science, Popline, PsycINFO, Google Scholar, Scielo, and Redalyc. We included studies that had a research question focused on self-managed abortion; and were published in English or Spanish. The combined search returned 7,167 studies; after screening, 99 studies were included in the analysis. Included studies reported on methods, procurement, characteristics of those who self-managed, effectiveness, safety, reasons for self-managed abortion, and emotional and physical experiences. Numerous abortion methods were reported, most frequently abortion with pills and herbs. Studies reporting on self-managed medication abortion reported high-levels of effectiveness. We identify gaps in the research, and make recommendations to address those gaps.

Objectives

To assess changes in Texas-resident border-state abortions, medication abortions, and abortions ≥22 weeks from last menstrual period (LMP) before and after implementation of House Bill 2 (HB2) in November 2013 and before and after the US Supreme Court's decision regarding HB2 in June 2016.

Study design

We conducted an interrupted time series analysis using 2012-2017 data on Texas-resident abortions in Arkansas, Louisiana, Oklahoma, and New Mexico. Data on procedure type and gestational age were available only for abortions in New Mexico.

Results

Border states reported 762 Texas-resident abortions in 2012, 1,673 in 2014, and 1,475 in 2017. Texas-resident abortions in all border states nearly doubled following HB2's implementation (incidence rate ratio [IRR]=1.92, 95% CI: 1.67-2.20). Border-state abortions then decreased by 19% after the 2016 US Supreme Court decision, compared to the period prior to the decision and after HB2's implementation (IRR=0.81, 95% CI: 0.73-0.91). From 2012 to 2014, the proportion of Texas-resident abortions in New Mexico that were medication abortion increased from 5% to 20% (p < 0.001) and the proportion that were ≥22 weeks from LMP decreased from 40% to 23% (p < p<0.001). Texas vital statistics undercounted annual out-of-state abortions, reporting only 13%-73% of abortions reported by border-state clinics during the study period.

Conclusions

HB2 was associated with increases in border-state abortions for Texas residents, including in the number of those ≥22 weeks from LMP. Border-state abortions declined after the Supreme Court ruled HB2 unconstitutional yet remained higher than pre-HB2 levels.

Implications statement

Abortion restrictions that severely curtail access may result in increases in travel out of state for care. Documenting out-of-state abortions is important for evaluating broader policy impacts and to prepare for future service disruptions. Texas residents may have more limited options for care if border states enact restrictive abortion laws.
