Basic Types of Abortion

Procedural Abortion, Medication Abortion, and Self-Managed Abortion

An essential initial step in advocating for Nurse Practitioners (NPs), midwives, and Physician Assistants (PAs) as abortion providers involves comprehensive education regarding the abortion procedure. Often, politicians, regulators, and healthcare practitioners lack awareness of the fundamental training required to become proficient providers of medication or early aspiration abortion. This knowledge gap can contribute to stigma and uninformed decisions that unjustly restrict provider training and limit abortion access.

 

While there are various types of abortion procedures, this Toolkit concentrates on the two methods predominantly utilized during the first trimester of pregnancy: aspiration and medication. The overwhelming majority of patients seeking abortion care do so within the first trimester, the period during which NPs, midwives, or PAs are most frequently engaged in providing such care. It's imperative to recognize that Advanced Practice Clinicians (APCs) can, depending on state laws, offer abortion care across all trimesters.

“Procedural” Versus “Surgical”: What’s in a Name?

The terminology employed in discussions about abortion plays a significant role in shaping perceptions. Referring to procedures as "procedural" rather than "surgical" can help dispel misconceptions surrounding abortion care. The term "surgical" erroneously implies a more complex level of care typically associated with surgeons and hospitals. Conversely, "procedural abortion" accurately reflects the nature of early abortion techniques, which are often straightforward and can be conducted using basic analgesics in primary care settings. Not only is the term procedural abortion clarifying, but it can also challenge the thinking that only physicians should provide abortion care and that this care needs to take place in more complex settings. 

 

Primary care providers, including NPs, midwives, and PAs, routinely perform a range of procedures, such as intrauterine device (IUD) insertion, endometrial biopsy, management of early pregnancy loss, and abortion. Adopting the terms "procedural" and "aspiration" abortion instead of "surgical" abortion constitutes small yet significant steps in demystifying early abortion techniques.

Medication vs. Aspiration Abortion

Medication

Medication abortion is a method of pharmacologic termination. Depending on the agent(s), the regimen, and the provider, medication abortion may be initiated as soon as a patient finds out she is pregnant. Most organizations will use 77 days of gestation as a cutoff, but medication abortion has been proven to be safe at later gestation. WHO recognizes that medication abortion is safe through up to 12 weeks of gestation (84 days). 

In 2013, early medical abortion accounted for about 22% of reported abortions in the United States.  As of February 24, 2022, medication abortion accounted for 54% of all abortions in the United States.

Designed as an educational tool to use with patients considering medication abortion, this short, animated video explains the basics of how medication abortion works and what patients should expect during and after treatment.

Although three medications are available in the U.S. - mifepristone, misoprostol, and methotrexate - methotrexate is rarely used today because of the greater availability and efficacy of regimens using the other drugs. Mifepristone blocks the uptake of progesterone by receptor cells in the uterus. Without this essential hormone, the lining of the uterus begins to break down, and the cervix softens. Misoprostol is a prostaglandin analog that stimulates uterine contractions and softens the cervix, facilitating uterine emptying.

Medication abortion is extremely safe and effective. The percentage of cases in which the medications do not successfully terminate the pregnancy and an aspiration procedure is necessary varies depending on the regimen, the gestational age of the pregnancy, and other factors, but in most studies, when evidence-based guidelines are followed, efficacy ranges from 95- 99.6%.

In March 2016, the FDA-approved updated labeling for mifepristone (Mifeprex®), bringing the label in alignment with what had been proven safe and effective and was standard medical practice recommended in the American Congress of Obstetricians and Gynecologists (ACOG) practice bulletin. Mifepristone is now used in 60% of all abortions carried out at or before 10 weeks.

Aspiration

In the first trimester, abortion can be performed as a simple office procedure using a vacuum aspirator. In aspiration abortion, the cervix usually is gradually stretched with tapered rods. After the cervix is dilated sufficiently, a plastic cannula attached to the suction apparatus is inserted into the uterus. Gentle suction (<60 mmHg) is applied to empty the contents of the uterus. Local anesthesia through paracervical and/or intracervical injection is almost universally used, and many clinics offer various other medications for relief of anxiety and pain management. Historically, pain during obstetric and gynecological procedures is under-managed due to historical racist and misogynistic practices. Aspiration abortion is highly effective, with success rates (complete abortion) at 99%. It is also one of the safest medical procedures and carries minimal risk, with a reported complication rate of 1-3%.

Later Abortion Care

Abortions later in pregnancy are safe, patient-centered, and done with thoughtful consideration and humanity. Generally speaking, most late abortions are done in an out-patient setting  using a combination of medication (mifeprex and misoprostol), feticidal injection depending on gestation, followed by D&E or Induction of Labor (IOL).  Before 24 weeks of pregnancy, D&E has been shown to be safer than IOL, though either may be enlisted depending on patient or provider preference (Pettit, Sweat, Zuber, Cotton-Caballero, Ferguson et al., 2017). Induced fetal demise by transabdominal or transcervical injection of digoxin/lidocaine/KCl is routinely done starting at periviability and beyond  (Diedrich, Goldfarb, Tattoo, Drey, Reeves et al., 2024) . “After-birth,”  “partial-birth,”  or “born-alive” abortions are not a practice done EVER - they are false narratives of the anti-abortion movement, meant to horrify and sway public sentiment, win political favor, and demonize pregnant people facing difficult life circumstances. All abortions are either “spontaneous” or “induced”, “medication” or “procedural” - referring to them otherwise, or in terms of  “viability” or “medical necessity” fuels stigma, hierarchies of deservedness, and perpetuates anti-abortion rhetoric and language ambiguities that are used to build restrictive abortion policy (Heuser, Sagaser, Christensen, Johnson, Lappen et al., 2023).  While abortion after 20 weeks carries more risk than that of 1st trimester care, most recent 2020 CDC findings report overall mortality related to abortion to be 0.45 deaths per 100,000 procedures - the lowest rate since 1973 (Kortsmit et al., 2023).  Again, when compared to induced abortion, the mortality risk of staying pregnant in the U.S. in 2020 is estimated to be 35-39 times higher, making a case for widespread abortion access across all stages of pregnancy.

Self-Managed Abortion

Self-managed abortion (SMA) is a common way for people to terminate their pregnancies. People choose SMA for a variety of reasons and use a variety of methods. Post-Dobbs, many people are choosing to self-manage their abortion at home with pills.
