Why Study Repeat Abortions? Majority of abortions result from unintended

pregnancy Repeat abortion = repeat unintended pregnancy

Women undergoing abortion are high risk group for future unintended pregnancy

Little known about women who undergo repeat abortions

Opportunity to provide long-acting reversible contraceptives

Abortions are Reportable to the NYC Bureau of Vital Statistics

NYC Health Code requires abortion reporting Within 5 days of event

Definition of abortion Purposeful interruption of intrauterine pregnancy Intention other than to produce live-born infant Does not result in live birth

80,000 abortions reported yearly

Estimated to capture 88% of procedures

Abortions are Reportable to the NYC Bureau of Vital Statistics

Healthcare provider or designee completes report form

Self report of past pregnancy outcomes Abortions, miscarriages, and births

Demographic and socioeconomic data Patient age Level of education Race/

ethnicity Method of payment

Zip code Marital status

Discussion Patient age


Race/ethnic disparities

Economic disparities

Limitations Self report of abortion history

Unit of analysis is abortion event, not woman

Missing values

Cannot exclude medically indicated abortions

Conclusions Repeat abortions comprised over half of all

abortions

Repeat abortion common across all sociodemographic characteristics

Race/ethnicity strongly correlated with repeat abortion

Next Steps Identify interventions to integrate with

abortion visits

Include post-abortion contraception in surveillance

Reduce barriers to provision of long-term contraception

Further research needed on race/ethnic disparities
