Hospital Discharge Against Medical Advice: When the Hospital Is Still Liable

Published 2026-05-27 · John Mahoney · MedLegal AI

Defense counsel often greets AMA-discharge cases as automatic wins: "The patient signed the form, left against advice, and died at home. That's contributory negligence, not malpractice." This is wrong — legally and clinically. AMA discharge is not a complete defense, and hospitals can remain liable in several common scenarios. This guide covers the plaintiff strategy when your client (or their family) was harmed after AMA discharge.

The Misconception

Most hospital AMA policies focus on documentation: get the patient to sign the AMA form, document the conversation, the patient is now responsible for their own outcome. This protects against most claims but has well-defined exceptions where hospital liability persists.

Capacity Is the Threshold Question

An AMA discharge is only valid if the patient had decision-making capacity at the time. Capacity has four legal elements:

1. Communication of choice — can the patient communicate a stable decision?
2. Understanding — does the patient understand the relevant information about diagnosis, prognosis, and treatment alternatives?
3. Appreciation — does the patient appreciate how the information applies to their own situation? (this is where many patients with depression, dementia, or substance intoxication fail)
4. Reasoning — can the patient compare options and weigh consequences in a reasoned way?

If any element is impaired, the patient lacks capacity and cannot validly refuse care. Common conditions that impair capacity:

• Acute intoxication (alcohol, opioids, benzodiazepines, illicit drugs)
• Delirium (common in hospitalized elderly, septic patients, post-op patients)
• Dementia (especially when patient does not understand prognosis)
• Acute psychiatric illness (mania, severe depression, psychosis)
• Untreated severe pain (which impairs reasoning)
• Hypoxia, hypoglycemia, electrolyte abnormalities
• Recent head injury

Standard of care: when a patient presents threatening to leave AMA and any of these conditions is present or suspected, the hospital must formally assess capacity (typically with a psychiatric consult or the validated MacArthur Competence Assessment Tool) and document the result. Failure to do so before letting the patient leave is breach.

Informed Refusal Standard

Just as a patient must give informed consent to a procedure, a patient refusing care must give informed refusal. Hospital must document:

1. The patient's diagnosis (or differential)
2. The recommended treatment
3. The expected outcome of treatment
4. The risks of refusing treatment, including specific harms (e.g., "you may die," "you may have a stroke," "you may lose your leg")
5. The alternatives to the recommended treatment
6. The patient's questions and the answers
7. The patient's stated reasons for refusing

An AMA form that says "patient refuses recommended treatment, accepts risks" is NOT sufficient informed refusal. The specific risks must be discussed, in language the patient understands, and documented.

The Liability Scenarios

1. Capacity not assessed

Patient with delirium, intoxication, or untreated mental illness signs AMA form and dies at home. Hospital failed to assess capacity. Liable.

2. Informed refusal inadequate

Patient signed AMA form but documentation doesn't show the specific risks were explained. Patient (or family) testifies they were not told they could die. Hospital liable for the failure to inform.

3. Discharge planning inadequate

Even if AMA is valid, the hospital has a duty to facilitate safe discharge: arrange follow-up, give clear return-precautions, provide bridge prescriptions if appropriate. If the hospital just sends the patient out the door without these steps and the patient dies, the discharge failure itself is a separate negligence claim.

4. EMTALA violations

If the patient came to the ED with an emergency medical condition, the hospital must stabilize before discharge regardless of AMA. EMTALA requires stabilization, not just offer of treatment.

5. Failure to involve family / surrogate decision-maker

When a patient's capacity is borderline or when they have a documented health-care proxy, the hospital should involve the surrogate before accepting AMA. Failure to do so when the patient's capacity was questionable is breach.

6. Pressure or coercion

Sometimes patients leave AMA because of long ED wait times, hospital staff behavior, or pressure to leave. If documented circumstances suggest the patient was effectively forced out, AMA is not a defense.

Discovery Targets

• AMA form and any supporting documentation
• Capacity assessment (formal psychiatric consult if performed; nursing notes if not)
• Vital signs at the time of AMA decision (acute physiologic abnormalities suggest capacity question)
• Laboratory studies suggesting impaired capacity (toxicology, glucose, electrolytes, ammonia)
• Medications administered before AMA (sedatives, opioids could impair capacity)
• Nursing notes describing the patient's behavior, speech, and orientation at AMA
• Discharge instructions provided (or not)
• Hospital's AMA policy and procedure
• Whether the patient was offered alternatives (against medical advice transfer to another facility, leaving with bridge medications, etc.)
• Whether family was contacted
• Patient's prior AMA history (some patients have a pattern of leaving AMA and the hospital knows this)

Standard of Care Sources

• American College of Emergency Physicians (ACEP) policy on patient capacity
• American Medical Association (AMA) ethics opinion on AMA discharge
• The Joint Commission AMA discharge standards
• Appelbaum & Grisso, "Assessing Patients' Capacity to Consent to Treatment" (NEJM) — landmark capacity framework
• Hospital's own AMA policy — often more rigorous than the legal minimum, and breach of internal policy is breach of standard of care

Damages

AMA-discharge cases involve typical malpractice damages: medical expenses for the preventable adverse outcome, wrongful death damages if the patient died, lost earnings, pain and suffering. Some jurisdictions reduce damages for comparative negligence if the patient's refusal contributed to their own harm — but the hospital's share remains substantial when capacity, informed refusal, or discharge planning was deficient.

Bottom Line

"They left AMA" is the first defense in many cases involving post-discharge adverse outcomes. It is rarely a complete defense. The key plaintiff questions are: was capacity validly assessed? Was informed refusal properly documented? Was discharge planning safe? Was the patient stable enough to leave? When the answer to any of these is no, the hospital remains liable regardless of the AMA form.
