A 28-year-old pregnant woman, G2P1, at 32 weeks gestation presents to the emergency department complaining of severe muscle aches, abdominal cramps, nausea, and diarrhea for the past 24 hours. She has a history of opioid use disorder and admits to using intranasal heroin daily, but reports she ran out yesterday. She also states she has been feeling profoundly sad, having low energy, and sleeping excessively over the past 3 weeks. Her medical records indicate two previous psychiatric hospitalizations for manic episodes characterized by grandiosity and a decreased need for sleep. Vital signs are temperature 37.2°C (99.0°F), blood pressure 140/90 mm Hg, heart rate 110/min, and respiratory rate 18/min. Physical examination reveals dilated pupils, frequent yawning, rhinorrhea, and piloerection. Fetal heart rate monitoring reveals a baseline of 150/min, moderate variability, positive accelerations, and no decelerations.

The physician counsels the patient on the risks of untreated opioid withdrawal during pregnancy, including preterm labor and fetal demise. The patient demonstrates a clear understanding of these risks but states, "I need to leave right now to take care of my 3-year-old at home. I refuse to be admitted, but I want to get better. I will come to the outpatient clinic tomorrow morning."

Which of the following is the most appropriate next step in management?

Administer a dose of sublingual buprenorphine and arrange for outpatient follow-upAnswer
B
Involuntarily admit the patient to the antepartum unit to protect the fetus
C
Perform an emergency cesarean delivery for impending fetal compromise
D
Notify child protective services immediately regarding her current pregnancy
E
Prescribe oral sertraline to treat her depressive symptoms

Answer

The most appropriate next step in management is to administer a dose of sublingual buprenorphine and arrange for outpatient follow-up.

This patient is experiencing acute opioid withdrawal, which in a pregnant patient poses a significant risk to the fetus, including fetal distress and preterm labor. She has decision-making capacity and has explicitly refused inpatient admission. Because competent pregnant patients have the legal right to refuse medical treatment, the physician cannot force an admission. The most appropriate immediate intervention is to treat her withdrawal to protect both her and the fetus. Administration of sublingual buprenorphine in the emergency department is safe, evidence-based, and effectively relieves withdrawal symptoms. Following stabilization, arranging close outpatient follow-up is the standard of care for a patient who declines hospitalization.

Step-by-Step Solution

Identify the patient's primary acute medical condition.

The patient is experiencing acute opioid withdrawal, evidenced by her history and clinical signs (myalgias, GI distress, dilated pupils, yawning, piloerection).

Recognizing acute withdrawal is critical because untreated withdrawal in a pregnant patient increases the risk of preterm labor, placental abruption, and fetal distress.

Determine the standard medical intervention for this condition in pregnancy.

Opioid agonist therapy (such as buprenorphine or methadone) is the standard of care to stabilize maternal opioid levels and protect the fetus.

It prevents withdrawal-induced fetal complications and reduces the risk of illicit substance relapse.

Evaluate the legal and ethical constraints regarding the patient's refusal of admission.

The patient clearly understands the risks, demonstrating decision-making capacity. Therefore, she cannot be held involuntarily.

A competent adult, including a pregnant woman, retains the absolute right to refuse medical treatment and hospitalization, regardless of the potential harm to the fetus.

Select the course of action that optimizes medical care while respecting patient autonomy.

Initiate sublingual buprenorphine in the emergency department and discharge her with a concrete outpatient follow-up plan.

This provides necessary, evidence-based medical treatment for her acute withdrawal without violating her right to refuse inpatient admission.
