Relapsed osteosarcoma, a phase 1 trial, and sepsis in a patient with a do-not-intubate order
A 16-year-old boy with relapsed osteosarcoma and bilateral pulmonary metastases has progressed after two lines of chemotherapy. He is alert, understands his prognosis, and wants to enroll in a phase 1 trial 4 hours from home. His parents want to stop 'toxic treatment' and enroll him in home hospice. He has chronic cancer pain on high-dose opioids and now presents with fever 39.3°C, ANC 120/µL, blood pressure 82/50 after 2 L of fluid, lactate 4.2 mmol/L, and oxygen saturation 89% on room air. He has a signed do-not-intubate order. He says, 'I don't want to die in the ICU, but I don't want to die tonight either.'
1. How do you assess his decision-making capacity, and how do you approach the disagreement between him and his parents?
Read the worked answer
Assess the four elements of capacity at the bedside: whether he understands the relevant information about the phase 1 trial, hospice, and his prognosis; whether he appreciates how those options apply to him; whether he can reason with the information; and whether he can express a consistent choice. Use plain language and teach-back, screen for depression, anxiety, and pain that could impair reasoning, and treat reversible delirium or opioid toxicity. A 16-year-old can have capacity for many decisions, although consent is usually joint with parents; his assent carries substantial ethical weight.
Rather than framing trial versus hospice as mutually exclusive, explore concurrent palliative care and a time-limited trial. Ask the parents what they fear most and what they believe he values. If disagreement persists, involve the ethics committee, a psychologist, and the primary oncology team. Do not coerce either side. If he lacks capacity, follow the parents' permission with his previously expressed wishes as a guide. Document the process and the rationale, and revisit it as his condition changes.
2. Does the do-not-intubate order change the immediate management of sepsis? What would a time-limited trial look like here?
Read the worked answer
A do-not-intubate order is not a do-not-treat order. It means he does not want endotracheal intubation, but it does not withhold antibiotics, fluids, oxygen, or comfort measures. He is septic and neutropenic: obtain blood cultures and give broad-spectrum antibiotics within 1 hour, continue fluid resuscitation while watching for pulmonary edema from his lung metastases, provide oxygen and noninvasive support as tolerated, and involve critical care early. Vasopressors may be consistent with his goals if they can be given outside an ICU or in a monitored setting; that should be discussed explicitly rather than assumed. Noninvasive ventilation may be acceptable to him even though intubation is not, but clarify that in advance.
A time-limited trial defines the interventions, the time frame, and the criteria for success. For example, give antibiotics, fluids, oxygen, and vasopressors for 24–48 hours with the goal of surviving this infection and returning home to make a decision about the trial; if he develops refractory hypoxia requiring intubation or multi-organ failure, transition to comfort-focused care. Reassess frequently and document his wishes.
3. What palliative and symptom management should be offered now, and how do you address his breathlessness and opioid tolerance?
Read the worked answer
Offer concurrent palliative care regardless of the trial decision. Treat pain with his usual long-acting opioid and short-acting breakthrough doses, and rotate or increase doses as needed because he is tolerant; do not withhold opioids for fear of respiratory depression in a dying patient, but monitor closely. For dyspnea, low-dose opioids are first-line, along with oxygen if hypoxemic, a fan, upright positioning, and treatment of fever and anxiety. Benzodiazepines can help anxiety and air hunger but may worsen sedation; use cautiously and titrate to comfort.
Address the family's fear of 'toxic treatment' by distinguishing disease-directed therapy from comfort care. Discuss home hospice versus inpatient palliative care, what can be delivered at home, and how a phase 1 trial would affect travel and symptom control. Involve social work, chaplaincy, and child life as appropriate. Ask about his goals for the remaining time, who he wants involved, and whether he wants to document preferences. Follow up on the ethical discussion and ensure the care plan is visible to all teams.
