Trends in use of medical abortion in the United States: reanalysis of surveillance data from the Centers for Disease Control and Prevention, 2001-2008

Time for Better Access to High-Quality Abortion Data in the United States

Despite considerable lay attention on the regulation and legislation of abortion in the United States, important gaps remain in our understanding of its incidence and health and social consequences since its legalization in 1973. Many of these gaps in knowledge can be attributed to a lack of access to high-quality, individual-level abortion data over the past 46 years. Herein, we review the strengths and limitations of different, currently available methods for enumerating abortions in the United States and discuss how lack of access to high-quality data limits our surveillance and research activities of not only abortion but other important reproductive and perinatal health outcomes. We conclude by discussing some potential opportunities for improved access to high-quality abortion data in the United States.

Post-abortion contraception before hospital discharge after installation of a surveillance network in Brazil

OBJECTIVE

To evaluate the use of contraception soon after abortion, ectopic, or molar pregnancy following the establishment of a surveillance network (MUSA).

METHODS

A cross-sectional study of women admitted for abortion, or ectopic or molar pregnancy at UNICAMP Women's Hospital (part of the MUSA Network), Campinas, Brazil, between July 2017 and August 2019. Clinical and sociodemographic data were compared between women who initiated contraception before discharge and those who did not by using a Cochran-Armitage test and multiple logistic regression.

RESULTS

Overall, 382 women were enrolled (mean ± SD age, 29.6 ± 7.4 years). Most women (287, 75.2%) had abortions, and 146 (38.2%) initiated contraception before hospital discharge. The most common contraceptives were injectables (75, 51.4%) followed by pills (65, 44.5%). Use of contraception increased during the study period (Z=3.69, P<0.01), mostly due to injectables (Z=3.84, P<0.01). Factors independently associated with contraceptive initiation were admission in 2019 (odds ratio [OR], 2.65; 95% confidence interval [CI], 1.36-5.17) and not having an abortion for legal reasons (OR, 3.54; 95% CI, 1.30-9.62).

CONCLUSION

Implementation of a surveillance network optimized the health service and quality of care. There was an increase in contraception use and a vulnerable population was identified.

Abortion Surveillance - United States, 2016

PROBLEM/CONDITION

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States.

PERIOD COVERED

2016.

DESCRIPTION OF SYSTEM

Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2016, data were received from 48 reporting areas. Abortion data provided by these 48 reporting areas for each year during 2007-2016 were used in trend analyses. Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births), respectively.

RESULTS

A total of 623,471 abortions for 2016 were reported to CDC from 48 reporting areas. Among these 48 reporting areas, the abortion rate for 2016 was 11.6 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 186 abortions per 1,000 live births. From 2015 to 2016, the total number of reported abortions decreased 2% (from 636,902), the abortion rate decreased 2% (from 11.8 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 1% (from 188 abortions per 1,000 live births). From 2007 to 2016, the total number of reported abortions decreased 24% (from 825,240), the abortion rate decreased 26% (from 15.6 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 18% (from 226 abortions per 1,000 live births). In 2016, all three measures reached their lowest level for the entire period of analysis (2007-2016). In 2016 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates. In 2016, women aged 20-24 and 25-29 years accounted for 30.0% and 28.5% of all reported abortions, respectively, and had abortion rates of 19.1 and 17.8 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. By contrast, women aged 30-34, 35-39, and ≥40 years accounted for 18.0%, 10.3%, and 3.5% of all reported abortions, respectively, and had abortion rates of 11.6, 6.9, and 2.5 abortions per 1,000 women aged 30-34, 35-39, and ≥40 years, respectively. From 2007 to 2016, the abortion rate decreased among women in all age groups. In 2016, adolescents aged <15 and 15-19 years accounted for 0.3% and 9.4% of all reported abortions, respectively, and had abortion rates of 0.4 and 6.2 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2007 to 2016, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 43%, and the abortion rate decreased 56%. This decrease in abortion rate was greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2016 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 25-39 years. Abortion ratios decreased from 2007 to 2016 for women in all age groups. In 2016, almost two-thirds (65.5%) of abortions were performed at ≤8 weeks' gestation, and nearly all (91.0%) were performed at ≤13 weeks' gestation. Fewer abortions were performed between 14 and 20 weeks' gestation (7.7%) or at ≥21 weeks' gestation (1.2%). During 2007-2016, the percentage of abortions performed at >13 weeks' gestation remained consistently low (8.2%-9.0%). Among abortions performed at ≤13 weeks' gestation, the percentage distributions of abortions by gestational age were highest among those performed at ≤6 weeks' gestation (35.0%-38.4%). In 2016, 27.9% of all abortions were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), 59.9% were performed by surgical abortion at ≤13 weeks' gestation, 8.8% were performed by surgical abortion at >13 weeks' gestation, and 3.4% were performed by medical abortion at >8 weeks' gestation; all other methods were uncommon (0.1%). Among those that were eligible for early medical abortion on the basis of gestational age (i.e., performed at ≤8 weeks' gestation), 41.9% were completed by this method. In 2016, women with one or more previous live births accounted for 59.0% of abortions, and women with no previous live births accounted for 41.0%. Women with one or more previous induced abortions accounted for 43.1% of abortions, and women with no previous abortions accounted for 56.9%. Deaths of women associated with complications from abortion are assessed as part of CDC's Pregnancy Mortality Surveillance System. In 2015, the most recent year for which data were reviewed for abortion-related deaths, two women were identified to have died as a result of complications from legal induced abortion and for one additional death, it was unknown whether the abortion was induced or spontaneous.

INTERPRETATION

Among the 48 areas that reported data every year during 2007-2016, decreases in the total number, rate, and ratio of reported abortions resulted in historic lows for the period of analysis for all three measures of abortion.

PUBLIC HEALTH ACTION

The data in this report can help program planners and policymakers identify groups of women with the highest rates of abortion. Unintended pregnancy is the major contributor to induced abortion. Increasing access to and use of effective contraception can reduce unintended pregnancies and further reduce the number of abortions performed in the United States.

Abortion Surveillance - United States, 2014

PROBLEM/CONDITION

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States.

PERIOD COVERED

2014.

DESCRIPTION OF SYSTEM

Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2014, data were received from 49 reporting areas. For trend analysis, abortion data were evaluated from 48 areas that reported data every year during 2005-2014. Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births).

RESULTS

A total of 652,639 abortions were reported to CDC for 2014. Of these abortions, 98.4% were from the 48 reporting areas that provided data every year during 2005-2014. Among these 48 reporting areas, the abortion rate for 2014 was 12.1 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 193 abortions per 1,000 live births. From 2013 to 2014, the total number and rate of reported abortions decreased 2%, and the ratio decreased 3%. From 2005 to 2014, the total number, rate, and ratio of reported abortions decreased 21%, 22%, and 18%, respectively. In 2014, all three measures reached their lowest level for the entire period of analysis (2005-2014). In 2014 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2014, women aged 20-24 and 25-29 years accounted for 32.2% and 26.7% of all reported abortions, respectively, and had abortion rates of 21.3 and 18.4 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 17.1%, 9.7%, and 3.6% of all reported abortions, respectively, and had abortion rates of 11.9, 7.2, and 2.6 abortions per 1,000 women aged 30-34 years, 35-39 years, and ≥40 years, respectively. From 2005 to 2014, the abortion rate decreased among women aged 20-24, 25-29, 30-34, and 35-39 years by 27%, 16%, 12%, and 5%, respectively, but increased 4% among women aged ≥40 years. In 2014, adolescents aged <15 and 15-19 years accounted for 0.3% and 10.4% of all reported abortions, respectively, and had abortion rates of 0.5 and 7.5 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2005 to 2014, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 38%, and their abortion rate decreased 49%. These decreases were greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2014 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 30-39 years. Abortion ratios decreased from 2005 to 2014 for women in all age groups. In 2014, the majority (64.9%) of abortions were performed at ≤8 weeks' gestation, and nearly all (91.0%) were performed at ≤13 weeks' gestation. Few abortions were performed between 14 and 20 weeks' gestation (7.7%) or at ≥21 weeks' gestation (1.3%). During 2005-2014, the percentage of all abortions performed at ≤13 weeks' gestation remained consistently high (≥90.9%). Among abortions performed at ≤13 weeks' gestation, there was a shift toward earlier gestational ages, as the percentage performed at ≤6 weeks' gestation increased 9%, and the percentage of all other gestational ages at ≤13 weeks' gestation decreased 0%-12%. In 2014, among reporting areas that included medical (nonsurgical) abortion on their reporting form, 22.5% of all abortions were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), 66.9% were performed by surgical abortion at ≤13 weeks' gestation, and 9.1% were performed by surgical abortion at >13 weeks' gestation; all other methods were uncommon (<1.5%). Among abortions performed at ≤8 weeks' gestation that were eligible for early medical abortion on the basis of gestational age, 33.3% were completed by this method. In 2014, women with one or more previous live births accounted for 59.5% of abortions, and women with no previous live births accounted for 40.4%. Women with one or more previous induced abortions accounted for 44.9% of abortions, and women with no previous abortion accounted for 55.1%. Women with three or more previous births accounted for 13.8% of abortions, and women with three or more previous abortions accounted for 8.6% of abortions. Deaths of women associated with complications from abortion for 2014 are being assessed as part of CDC's Pregnancy Mortality Surveillance System. In 2013, the most recent year for which data were available, four women were identified to have died as a result of complications from legal induced abortion.

INTERPRETATION

Among the 48 areas that reported data every year during 2005-2014, the decreases in the total number, rate, and ratio of reported abortions that occurred during 2010-2013 continued from 2013 to 2014, resulting in historic lows for all three measures of abortion.

PUBLIC HEALTH ACTION

The data in this report can help program planners and policymakers identify groups of women with the highest rates of abortion. Unintended pregnancy is the major contributor to induced abortion. Increasing access to and use of effective contraception can reduce unintended pregnancies and further reduce the number of abortions performed in the United States.

Abortion Surveillance - United States, 2015

PROBLEM/CONDITION

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States.

PERIOD COVERED

DESCRIPTION OF SYSTEM

Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2015, data were received from 49 reporting areas. Abortion data provided by these 49 reporting areas for each year during 2006-2015 were used in trend analyses. Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births), respectively.

RESULTS

A total of 638,169 abortions for 2015 were reported to CDC from 49 reporting areas. Among these 49 reporting areas, the abortion rate for 2015 was 11.8 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 188 abortions per 1,000 live births. From 2014 to 2015, the total number of reported abortions decreased 2% (from 652,639), the abortion rate decreased 2% (from 12.1 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 2% (from 192 abortions per 1,000 live births). From 2006 to 2015, the total number of reported abortions decreased 24% (from 842,855), the abortion rate decreased 26% (from 15.9 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 19% (from 233 abortions per 1,000 live births). In 2015, all three measures reached their lowest level for the entire period of analysis (2006-2015). In 2015 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women aged ≥30 years accounted for a smaller percentage of abortions and had lower abortion rates. In 2015, women aged 20-24 and 25-29 years accounted for 31.1% and 27.6% of all reported abortions, respectively, and had abortion rates of 19.9 and 17.9 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 17.7%, 10.0%, and 3.5% of all reported abortions, respectively, and had abortion rates of 11.6, 7.0, and 2.5 abortions per 1,000 women aged 30-34, 35-39, and ≥40 years, respectively. From 2006 to 2015, the abortion rate decreased among women in all age groups. In 2015, adolescents aged <15 and 15-19 years accounted for 0.3% and 9.8% of all reported abortions, respectively, and had abortion rates of 0.5 and 6.7 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2006 to 2015, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 41%, and their abortion rate decreased 54%. This decrease in abortion rate was greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2015 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 25-39 years. Abortion ratios decreased from 2006 to 2015 for women in all age groups. In 2015, almost two thirds (65.4%) of abortions were performed at ≤8 weeks' gestation, and nearly all (91.1%) were performed at ≤13 weeks' gestation. Few abortions were performed between 14 and 20 weeks' gestation (7.6%) or at ≥21 weeks' gestation (1.3%). During 2006-2015 the percentage of all abortions performed at >13 weeks' gestation remained consistently low (≤9.0%). Among abortions performed at ≤13 weeks' gestation, a shift occurred toward earlier gestational ages, with the percentage performed at ≤6 weeks' gestation increasing 11%. In 2015, 24.6% of all abortions were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), 64.3% were performed by surgical abortion at ≤13 weeks' gestation, and 8.8% were performed by surgical abortion at >13 weeks' gestation; all other methods were uncommon (≤2.2%). Among those that were eligible for early medical abortion on the basis of gestational age (i.e., performed at ≤8 weeks' gestation), 35.8% were completed by this method. In 2015, women with one or more previous live births accounted for 59.3% of abortions, and women with no previous live births accounted for 40.7%. Women with one or more previous induced abortions accounted for 43.6% of abortions, and women with no previous abortion accounted for 56.3%. Women with three or more previous births accounted for 14.2% of abortions, and women with three or more previous abortions accounted for 8.2% of abortions. Deaths of women associated with complications from abortion for 2015 are being assessed as part of CDC's Pregnancy Mortality Surveillance System. In 2014, the most recent year for which data were available, six women were identified to have died as a result of complications from legal induced abortion.

In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 17.1%, 9.7%, and 3.6% of all reported abortions, respectively, and had abortion rates of 11.9, 7.2, and 2.6 abortions per 1,000 women aged 30-34 years, 35-39 years, and ≥40 years, respectively. From 2005 to 2014, the abortion rate decreased among women aged 20-24, 25-29, 30-34, and 35-39 years by 27%, 16%, 12%, and 5%, respectively, but increased 4% among women aged ≥40 years. In 2014, adolescents aged <15 and 15-19 years accounted for 0.3% and 10.4% of all reported abortions, respectively, and had abortion rates of 0.5 and 7.5 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2005 to 2014, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 38%, and their abortion rate decreased 49%. These decreases were greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2014 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 30-39 years. Abortion ratios decreased from 2005 to 2014 for women in all age groups. In 2014, the majority (67.0%) of abortions were performed at ≤8 weeks' gestation, and nearly all (91.5%) were performed at ≤13 weeks' gestation. Few abortions were performed between 14 and 20 weeks' gestation (7.2%) or at ≥21 weeks' gestation (1.3%). During 2005-2014, the percentage of all abortions performed at ≤13 weeks' gestation remained consistently high (≥91.4%). Among abortions performed at ≤13 weeks' gestation, there was a shift toward earlier gestational ages, as the percentage performed at ≤6 weeks' gestation increased 21%, and the percentage of all other gestational ages at ≤13 weeks' gestation decreased 7%-20%.

INTERPRETATION

Among the 48 areas that reported data every year during 2005-2014, the decreases in the total number, rate, and ratio of reported abortions that occurred during 2010-2013 continued from 2013 to 2014, resulting in historic lows for all three measures of abortion.

PUBLIC HEALTH ACTION

The data in this report can help program planners and policymakers identify groups of women with the highest rates of abortion. Unintended pregnancy is the major contributor to induced abortion. Increasing access to and use of effective contraception can reduce unintended pregnancies and further reduce the number of abortions performed in the United States.

Quantity over quality-Findings from a systematic review and environmental scan of patient decision aids on early abortion methods

Background

The availability and effectiveness of decision aids (DAs) on early abortion methods remain unknown, despite their potential for supporting women's decision making.

Objective

To describe the availability, impact and quality of DAs on surgical and medical early abortion methods for women seeking induced abortion.

Search strategy

For the systematic review, we searched MEDLINE, Cochrane Library, CINAHL, EMBASE and PsycINFO. For the environmental scan, we searched Google and App Stores and consulted key informants.

Inclusion criteria

For the systematic review, we included studies evaluating an early abortion method DA (any format and language) vs a comparison group on women's decision making. DAs must have met the Stacey et al (2014). Cochrane review definition of DAs. For the environmental scan, we included English DAs developed for the US context.

Data extraction and synthesis

We extracted study and DA characteristics, assessed study quality using the Effective Practice and Organization of Care risk of bias tool and assessed DA quality using International Patient Decision Aid Standards (IPDAS).

Results

The systematic review identified one study, which found that the DA group had higher knowledge and felt more informed. The evaluated DA met few IPDAS criteria. In contrast, the environmental scan identified 49 DAs created by non‐specialists. On average, these met 28% of IPDAS criteria for Content, 22% for Development and 0% for Effectiveness.

Conclusions

Research evaluating DAs on early abortion methods is lacking, and although many tools are accessible, they demonstrate suboptimal quality. Efforts to revise existing or develop new DAs, support patients to identify high‐quality DAs and facilitate non‐specialist developers' adoption of best practices for DA development are needed.

Abortion Surveillance - United States, 2013

PROBLEM/CONDITION

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States.

PERIOD COVERED

2013.

DESCRIPTION OF SYSTEM

Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2013, data were received from 49 reporting areas. For trend analysis, abortion data were evaluated from 47 areas that reported data every year during 2004-2013. Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births).

RESULTS

A total of 664,435 abortions were reported to CDC for 2013. Of these abortions, 98.2% were from the 47 reporting areas that provided data every year during 2004-2013. Among these 47 reporting areas, the abortion rate for 2013 was 12.5 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 200 abortions per 1,000 live births. From 2012 to 2013, the total number, rate, and ratio of reported abortions decreased 5%. From 2004 to 2013, the total number, rate, and ratio of reported abortions decreased 20%, 21%, and 17%, respectively. In 2013, all three measures reached their lowest level for the entire period of analysis (2004-2013). In 2013 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2013, women aged 20-24 and 25-29 years accounted for 32.7% and 25.9% of all abortions, respectively, and had abortion rates of 21.8 and 18.2 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 16.8%, 9.2%, and 3.6% of all abortions, respectively, and had abortion rates of 11.8, 7.0, and 2.5 abortions per 1,000 women aged 30-34 years, 35-39 years, and ≥40 years, respectively. During 2004-2013, the decrease in abortion rates among adult women aged 20-39 years ranged from 8% to 27% across these age groups, whereas the abortion rate was stable for women aged ≥40 years. In 2013, adolescents aged <15 and 15-19 years accounted for 0.3% and 11.4% of all abortions, respectively, and had abortion rates of 0.6 and 8.2 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2004 to 2013, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 31% and their abortion rate decreased 46%. These decreases were greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2013 and throughout the entire period of analysis were highest among adolescents and lowest among women aged 30-39 years. Abortion ratios decreased from 2004 to 2013 for women in all age groups, except for adolescents aged <15 years. In 2013, the majority (66.0%) of abortions were performed by ≤8 weeks' gestation, and nearly all (91.6%) were performed by ≤13 weeks' gestation. Few abortions were performed between 14 and 20 weeks' gestation (7.1%) or at ≥21 weeks' gestation (1.3%). From 2004 to 2013, the percentage of all abortions performed at ≤13 weeks' gestation remained consistently high (≥91.5%) and among those performed at ≤13 weeks' gestation, the percentage performed at ≤6 weeks' gestation increased 16%. In 2013, among the 43 reporting areas that included medical (nonsurgical) abortion on their reporting form, a total of 67.9% of abortions were performed by curettage at ≤13 weeks' gestation, 22.2% were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), and 8.6% were performed by curettage at >13 weeks' gestation; all other methods were uncommon. Among abortions performed at ≤8 weeks' gestation that were eligible for early medical abortion on the basis of gestational age, 32.8% were completed by this method. From 2012 to 2013, the percentage of abortions reported as early medical abortions increased 5%. Deaths of women associated with complications from abortion for 2013 are being investigated as part of CDC's Pregnancy Mortality Surveillance System. In 2012, the most recent year for which data were available, four women were identified to have died as a result of complications from known legal induced abortion. No reported deaths were associated with known illegal induced abortion.

INTERPRETATION

Among the 47 areas that reported data every year during 2004-2013, the decreases in the total number, rate, and ratio of reported abortions that occurred during 2009-2012 continued from 2012 to 2013, resulting in historic lows for all three measures of abortion.

PUBLIC HEALTH ACTION

The data in this report can help program planners and policymakers identify groups of women with highest rates of abortion. Unintended pregnancy is the major contributor to abortion. Increasing access to and use of contraception, including the most effective methods, can reduce unintended pregnancies and further reduce the number of abortions performed in the United States.

Abortion Surveillance - United States, 2012

PROBLEM/CONDITION

Since 1969, CDC has conducted abortion surveillance to document the number and characteristics of women obtaining legal induced abortions in the United States.

REPORTING PERIOD COVERED

2012.

DESCRIPTION OF SYSTEM

Each year, CDC requests abortion data from the central health agencies of 52 reporting areas (the 50 states, the District of Columbia, and New York City). The reporting areas provide this information voluntarily. For 2012, data were received from 49 reporting areas. For trend analysis, abortion data were evaluated from 47 areas that reported data every year during 2003-2012. Census and natality data, respectively, were used to calculate abortion rates (number of abortions per 1,000 women) and ratios (number of abortions per 1,000 live births).

RESULTS

A total of 699,202 abortions were reported to CDC for 2012. Of these abortions, 98.4% were from the 47 reporting areas that provided data every year during 2003-2012. Among these same 47 reporting areas, the abortion rate for 2012 was 13.2 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 210 abortions per 1,000 live births. From 2011 to 2012, the total number and ratio of reported abortions decreased 4% and the abortion rate decreased 5%. From 2003 to 2012, the total number, rate, and ratio of reported abortions decreased 17%, 18%, and 14%, respectively, and reached their lowest level in 2012 for the entire period of analysis (2003-2012). In 2012 and throughout the period of analysis, women in their 20s accounted for the majority of abortions and had the highest abortion rates; women in their 30s and older accounted for a much smaller percentage of abortions and had lower abortion rates. In 2012, women aged 20-24 and 25-29 years accounted for 32.8% and 25.4% of all abortions, respectively, and had abortion rates of 23.3 and 18.9 abortions per 1,000 women aged 20-24 and 25-29 years, respectively. In contrast, women aged 30-34, 35-39, and ≥40 years accounted for 16.4%, 9.1%, and 3.7% of all abortions, respectively, and had abortion rates of 12.4, 7.3, and 2.8 abortions per 1,000 women aged 30-34 years, 35-39 years, and ≥40 years, respectively. Throughout the period of analysis, abortion rates decreased among women aged 20-24, 25-29, and 30-34 years by 24%, 18%, and 10%, respectively, whereas they increased among women aged ≥40 years by 8%. In 2012, adolescents aged <15 and 15-19 years accounted for 0.4% and 12.2% of all abortions, respectively, and had abortion rates of 0.8 and 9.2 abortions per 1,000 adolescents aged <15 and 15-19 years, respectively. From 2003 to 2012, the percentage of abortions accounted for by adolescents aged 15-19 years decreased 27% and their abortion rate decreased 40%. These decreases were greater than the decreases for women in any older age group. In contrast to the percentage distribution of abortions and abortion rates by age, abortion ratios in 2012 and throughout the entire period of analysis were highest among adolescents aged ≤19 years and lowest among women aged 30-39 years. Abortion ratios decreased from 2003 to 2012 for women in all age groups. In 2012, the majority (65.8%) of abortions were performed by ≤8 weeks' gestation, and nearly all (91.4%) were performed by ≤13 weeks' gestation. Few abortions (7.2%) were performed between 14-20 weeks' gestation or at ≥21 weeks' gestation (1.3%). From 2003 to 2012, the percentage of all abortions performed at ≤8 weeks' gestation increased 7%; the percentage performed at >13 weeks remained consistently low (≤9.0%). In 2012, among the 40 reporting areas that included medical (nonsurgical) abortion on their reporting form, a total of 69.4% of abortions were performed by curettage at ≤13 weeks' gestation, 20.8% were performed by early medical abortion (a nonsurgical abortion at ≤8 weeks' gestation), and 8.7% were performed by curettage at >13 weeks' gestation; all other methods were uncommon. Among abortions performed at ≤8 weeks' gestation that were eligible on the basis of gestational age for early medical abortion, 30.8% were completed by this method. The percentage of abortions reported as early medical abortions increased 10% from 2011 to 2012. Deaths of women associated with complications from abortions for 2012 are being investigated as part of CDC's Pregnancy Mortality Surveillance System. In 2011, the most recent year for which data were available, two women were identified to have died as a result of complications from known legal induced abortions. No reported deaths were associated with known illegal induced abortions.

INTERPRETATION

Among the 47 areas that reported data every year during 2003-2012, the notable decreases that occurred during 2008-2011 in the total number, rate, and ratio of reported abortions continued from 2011 to 2012 and resulted in historic lows for all three measures of abortion.

PUBLIC HEALTH ACTIONS

The data in this report can help to identify groups of women at greatest risk for abortion and can be used to guide and evaluate prevention efforts. Because unintended pregnancy is the major contributor to abortion, and unintended pregnancies are rare among women who use the most effective methods of contraception, increasing access to and use of these methods can help further reduce the number of unintended pregnancies, and therefore abortions, performed in the United States.

Abortion-Related Mortality in the United States: 1998-2010

OBJECTIVE

To examine characteristics and causes of legal induced abortion-related deaths in the United States between 1998 and 2010.

METHODS

Abortion-related deaths were identified through the national Pregnancy Mortality Surveillance System with enhanced case-finding. We calculated the abortion mortality rate by race, maternal age, and gestational age and the distribution of causes of death by gestational age and procedure.

RESULTS

During the period from 1998-2010, of approximately 16.1 million abortion procedures, 108 women died, for a mortality rate of 0.7 deaths per 100,000 procedures overall, 0.4 deaths for non-Hispanic white women, 0.5 deaths for Hispanic women, and 1.1 deaths for black women. The mortality rate increased with gestational age, from 0.3 to 6.7 deaths for procedures performed at 8 weeks or less and at 18 weeks or greater, respectively. A majority of abortion-related deaths at 13 weeks of gestation or less were associated with anesthesia complications and infection, whereas a majority of abortion-related deaths at more than 13 weeks of gestation were associated with infection and hemorrhage. In 20 of the 108 cases, the abortion was performed as a result of a severe medical condition where continuation of the pregnancy threatened the woman's life.

CONCLUSION

Deaths associated with legal induced abortion continue to be rare events-less than 1 per 100,000 procedures. Primary prevention of unintended pregnancy, including those in women with serious pre-existing medical conditions, and increased access to abortion services at early gestational ages may help to further decrease abortion-related mortality in the United States.

Evaluating New York City's abortion reporting system: insights for public health data collection systems

CONTEXT

New York City (NYC) mandates reporting of all abortion procedures. These reports enable tracking of abortion incidence and underpin programs, policy, and research. Since January 2011, the majority of abortion facilities must report electronically.

OBJECTIVES

We conducted an evaluation of NYC's abortion reporting system and its transition to electronic reporting. We summarize the evaluation methodology and results and draw lessons relevant to other vital statistics and public health reporting systems.

DESIGN

The evaluation followed Centers for Disease Control and Prevention guidelines for evaluating public health surveillance systems. We interviewed key stakeholders and conducted a data provider survey. In addition, we compared the system's abortion counts with external estimates and calculated the proportion of missing and invalid values for each variable on the report form. Finally, we assessed the process for changing the report form and estimated system costs.

SETTING

NYC Health Department's Bureau of Vital Statistics.

MAIN OUTCOME MEASURES

Usefulness, simplicity, flexibility, data quality, acceptability, sensitivity, timeliness, and stability of the abortion reporting system.

RESULTS

Ninety-five percent of abortion data providers considered abortion reporting important; 52% requested training regarding the report form. Thirty percent reported problems with electronic biometric fingerprint certification, and 18% reported problems with the electronic system's stability. Estimated system sensitivity was 88%. Of 17 variables, education and ancestry had more than 5% missing values in 2010. Changing the electronic reporting module was costly and time-consuming. System operating costs were estimated at $80 136 to $89 057 annually.

CONCLUSIONS

The NYC abortion reporting system is sensitive and provides high-quality data, but opportunities for improvement include facilitating biometric certification, increasing electronic platform stability, and conducting ongoing outreach and training for data providers. This evaluation will help data users determine the degree of confidence that should be placed on abortion data. In addition, the evaluation results are applicable to other vital statistics reporting and surveillance systems.

Medical versus surgical methods of early abortion: protocol for a systematic review and environmental scan of patient decision aids

INTRODUCTION

Currently, we lack understanding of the content, quality and impact of patient decision aids to support decision-making between medical and surgical methods of early abortion. We plan to undertake a systematic review of peer-reviewed literature to identify, appraise and describe the impact of early abortion method decision aids evaluated quantitatively (Part I), and an environmental scan to identify and appraise other early abortion method decision aids developed in the US (Part II).

METHODS AND ANALYSIS

For the systematic review, we will search PubMed, Cochrane Library, CINAHL, EMBASE and PsycINFO databases for articles describing experimental and observational studies evaluating the impact of an early abortion method decision aid on women's decision-making processes and outcomes. For the environmental scan, we will identify decision aids by supplementing the systematic review search with Internet-based searches and key informant consultation. The primary reviewer will assess all studies and decision aids for eligibility, and a second reviewer will also assess a subset of these. Both reviewers will independently assess risk of bias in the studies and abstract data using a piloted form. Finally, both reviewers will assess decision aid quality using the International Patient Decision Aid Standards criteria, ease of readability using Flesch/Flesch-Kincaid tests, and informational content using directed content analysis.

ETHICS AND DISSEMINATION

As this study does not involve human subjects, ethical approval will not be sought. We aim to disseminate the findings in a scientific journal, via academic and/or professional conferences and among the broader community to contribute knowledge about current early abortion method decision-making support.

TRIAL REGISTRATION NUMBER

This protocol is registered in the International Prospective Register of Systematic Reviews (CRD42015016717).

Public Health Impact of Legal Termination of Pregnancy in the US: 40 Years Later

During the 40 years since the US Supreme Court decision in Doe versus Wade and Doe versus Bolton, restrictions on termination of pregnancy (TOP) were overturned nationwide. The use of TOP was much wider than predicted and a substantial fraction of reproductive age women in the U.S. have had one or more TOPs and that widespread uptake makes the downstream impact of any possible harms have broad public health implications. While short-term harms do not appear to be excessive, from a public perspective longer term harm is conceiving, and clearly more study of particular relevance concerns the associations of TOP with subsequent preterm birth and mental health problems. Clearly more research is needed to quantify the magnitude of risk and accurately inform women with the crisis of unintended pregnancy considering TOP. The current US data-gathering mechanisms are inadequate for this important task.
