Friday at 4:55 p.m.: The Amputation Refusal
Friday, 4:55 p.m. A vascular surgery intern pages psychiatry about Mr. R, a 45-year-old man with type 1 diabetes, osteomyelitis of the left foot, and severe peripheral arterial disease. Below-knee amputation is scheduled for 7 a.m. tomorrow and he refuses, saying 'I'd rather die than lose this leg.' He has been admitted three days: temperature 38.2 C, WBC 18, glucose 340, creatinine 1.6 (baseline 0.9). He has a 10-year history of heroin injection and has been on methadone 80 mg daily for two years; the opioid treatment program was closed yesterday for a holiday, so he has missed two doses. He is yawning, sweating, and irritable, with dilated pupils and piloerection, and he is asking to leave against medical advice. The intern says: 'We need a capacity eval so he'll agree to surgery.' The nurse's note says 'patient appears depressed, possibly suicidal.'
1. You are paged at 4:55 p.m. on Friday. What is your first move, and how do you reframe the question you were asked?

Triage by treatable urgency. The most time-critical psychiatric issue tonight is untreated opioid withdrawal, which is producing agitation, dysphoria, and the wish to leave - and which will invalidate any capacity assessment performed in the next hour. Treating withdrawal is also the fastest way to build an alliance.
Reframe the consult in the phone call. Say explicitly: 'I will not be obtaining consent and I am not providing surgical clearance; that is not what a capacity consultation does.' Then ask three questions:
- Is the limb threatening his life tonight - gas, wet gangrene, necrotizing infection, septic shock? If so, this is a medical emergency with a different pathway (emergency doctrine, ethics, immediate senior involvement).
- Is 7 a.m. a hard clinical deadline, or an OR slot? For osteomyelitis with adequate IV antibiotics, most amputations can safely wait 24–72 hours - the surgeon should state the actual deadline.
- Is there a health care agent or surrogate, and has anyone asked him what he would need to say yes?
Set the frame you will deliver: 'Is he currently able to make this decision? If not, what reversible factors can we correct in the next 12 hours, and who decides?' The 'possibly suicidal' note also needs clarification - 'I would rather die than lose my leg' is a statement about values, not intent. Ask him directly about intent, plan, and means, and document the answer rather than the label.
2. How do you assess capacity here, and how does untreated opioid withdrawal affect that assessment?
Read the worked answer
Four abilities: communicate a choice, understand the relevant information, appreciate the situation and its consequences, and reason about alternatives. Refusing amputation is high-stakes and irreversible, so the evidentiary bar is high - which argues for careful reassessment, not for overriding him.
Fix the confounds first. Untreated withdrawal produces autonomic arousal, insomnia, dysphoria, and impaired attention: a capacity interview conducted while he is yawning, sweating, and desperate to leave will not be valid. Before reassessing:
- Confirm the methadone dose with the opioid treatment program's after-hours line; continue 80 mg inpatient or bridge with buprenorphine if methadone cannot be obtained quickly.
- Check glucose and ketones, treat pain, assess for sepsis and delirium (CAM), and give him a night's sleep.
Then probe his reasoning, not just his answer. Ask why. Common, rational reasons: fear of uncontrolled post-operative pain, prior surgical trauma, fear of losing mobility or his job, fear of being unable to reach the methadone clinic, fear that opioids prescribed for surgical pain will destabilize his recovery, or a wish not to survive disabled. A choice can be values-consistent, well reasoned, and still unwise - that is capacity, not incapacity.
Then offer what would change the calculus: a written post-operative pain plan, addiction medicine involvement, a peer visit from an amputee, rehabilitation projections, a second surgical opinion. If he remains capable, respect the refusal and document the content of the assessment. If he lacks capacity and there is a limb- or life-threatening process, use the surrogate or, narrowly, emergency provisions, and involve ethics.
3. He asks to leave against medical advice. What do you recommend, and how do you communicate it to the surgical team?
Read the worked answer
The AMA decision is its own capacity question. If he has capacity to leave, he may leave; you cannot detain him to compel surgery. If he lacks capacity because of delirium or intoxication and there is an immediate threat to life, follow the local hold statute and say plainly which statute you are invoking.
If he goes, make leaving safer than it would otherwise be: methadone dose arranged with the program or a bridge prescription, a wound-care plan, an outpatient appointment, harm-reduction counseling, and a number to call. A documented safe-exit plan is not an endorsement.
Talk to the attending surgeon, not the intern. Use a structured handoff:
- What I found: withdrawal, hyperglycemia, possible sepsis, and a capacity assessment performed before and after treatment.
- The reversible factors and the timeframe I recommend: reassess at 7 a.m. after methadone and glucose control, before the OR.
- His stated reasons, in his words.
- What would help: pain plan, addiction medicine consult, peer support, a stated clinical deadline.
- What I will document.
Address documentation and stigma. Ask that 'noncompliant,' 'drug-seeking,' and 'suicidal' be replaced with behavioral descriptions and direct quotes; these labels follow patients and bias the next team. Offer to co-lead a family meeting and to request an ethics consult if the team wants to proceed over his objection. Finally, since it is Friday evening, name who is covering and what the plan is for Saturday - a consult that ends with a phone call and no plan is a systems failure, not a psychiatric one.
