DNR and DNI Orders Do NOT Legally Prohibit Antibiotics or Basic Medications
DNR (Do-Not-Resuscitate) and DNI (Do-Not-Intubate) orders are legally and ethically limited to specific interventions—cardiac resuscitation and intubation respectively—and do not authorize withholding antibiotics or other basic medications unless explicitly documented as part of a broader goals-of-care discussion.
Understanding What DNR/DNI Actually Means
DNR and DNI orders are frequently misunderstood by both healthcare providers and patients, leading to inappropriate withholding of beneficial treatments. The core issue is that these orders specify only what should not be done in specific clinical scenarios:
- DNR: No chest compressions, defibrillation, or cardiac resuscitation during cardiac arrest
- DNI: No endotracheal intubation (though this requires careful clarification about whether it applies only during arrest or in all circumstances)
These orders do not constitute blanket limitations on medical care 1, 2.
What Should Be Discontinued vs. Continued
The 2016 ICU guidelines on withdrawal of life-sustaining measures provide clear direction when the decision has been made to withdraw life support entirely—a fundamentally different situation from simply having DNR/DNI orders 3:
When actively withdrawing life support (not merely having DNR/DNI status):
- Discontinue: vasopressors, inotropes, dialysis, blood transfusions, parenteral nutrition, tube feeding, antibiotics, IV fluids, and blood work
- Continue: comfort medications (opioids, sedatives, antiemetics)
However, this applies only when the explicit goal is comfort-focused end-of-life care, not to all patients with DNR/DNI orders.
The Critical Distinction
Having DNR/DNI orders does not automatically mean a patient is receiving comfort care only. Many patients with DNR/DNI orders:
- Still want aggressive medical treatment
- May benefit from ICU admission
- Should receive antibiotics for treatable infections
- Deserve full medical and surgical interventions short of the specific prohibited measures
Research demonstrates that healthcare providers inappropriately restrict care based on DNR/DNI status. Emergency medicine residents were significantly less willing to offer central lines (88.2% vs 97.2%), ICU admission (89.9% vs 99.0%), dialysis (79.3% vs 98.0%), and surgical consultation (78.7% vs 94.2%) to DNR/DNI patients compared to full-code patients—despite no documented refusal of these interventions 4.
Common Pitfalls to Avoid
Conflating DNR/DNI with "comfort care only": These are separate decisions requiring separate conversations 1, 2
Assuming DNR/DNI means "do everything else less aggressively": This violates patient autonomy and informed consent 4
Using combined "DNR/DNI" terminology without documenting intubation preferences for non-arrest situations: One study found 26% of patients labeled "DNR/DNI" had no documentation of informed refusal of intubation for non-arrest indications 1
Failing to discuss specific interventions individually: The ASA guidelines emphasize explicitly discussing each intervention separately, including blood transfusions and antibiotics, rather than bundling decisions 5
Legal and Ethical Framework
Withholding antibiotics or basic medications from a patient with DNR/DNI orders—without explicit documentation that the patient has refused these specific treatments—is legally problematic because:
- It violates informed consent principles
- It exceeds the scope of the DNR/DNI order
- It may constitute abandonment or negligence
- It contradicts the patient's right to self-determination
The only legal basis for withholding antibiotics would be:
- Explicit documented refusal by the patient or appropriate surrogate after informed discussion
- Clear documentation that goals of care have transitioned to comfort-focused measures only
- Medical futility in the specific clinical context (though this remains ethically complex)
Practical Approach
When encountering a patient with DNR/DNI orders who develops an infection or other treatable condition:
- Review the actual documentation: What exactly did the patient consent to or refuse?
- Clarify goals of care: Is the patient pursuing disease-directed treatment or comfort-only care?
- Have a specific conversation about the intervention in question (e.g., antibiotics for pneumonia)
- Document clearly: Record the patient's preferences for each category of intervention separately
- Default to treatment if goals are unclear and the patient cannot communicate, unless there is explicit documentation otherwise
The 2023 palliative care guidelines emphasize that decisions about specific interventions should be individualized based on therapeutic goals, prognosis, and quality of life considerations—but this requires active discussion, not assumptions based on code status 6.
In summary: DNR/DNI orders alone provide no legal authority to withhold antibiotics or other basic medications. Such decisions require separate, documented informed consent discussions about goals of care and specific treatment preferences.
