This review pro- vides the information clinicians need to prepare for an increasingly restrictive legal climate for abortion. Ultimately, we conclude that appropriate care is centered on two clinical concepts. First, because medication-induced abortion and spontane- ous abortion are clinically similar processes, care can usually be given without knowledge of whether the abortion is self-managed or spontaneous. Second, be- cause medication-induced abortion is safe, many patients who seek care will re- quire only confirmation that their abortion is complete or outpatient intervention for incomplete abortion. In contrast, those using unsafe methods may need life- saving critical care for sepsis, hemorrhage, pelvic-organ injury, or toxic exposures. The hallmark of skilled care in this new era will be judicious use of intervention in most cases and readiness for aggressive treatment when needed. Appropriate care also involves understanding that women’s legal safety — their risk of prosecution — may be the biggest threat to their well-being. Seven states criminalize self-managed abortion, and 24 others have laws that can be inter- preted as doing so.6 However, no state mandates that health care providers report suspected or confirmed self-managed abortion, including for minors.6 Indeed, reporting may violate patients’ privacy rights and result in penalties for those who report. Reporting is also problematic because caregivers are more likely to report women of color and low-income women than white or affluent women in similar circumstances.7 When patients present with bleeding in pregnancy and caregivers involve the police, patients may face detention and prosecution, regardless of whether they induced the abortion.
