2.Specific circumstances

Pregnant patients
Recognize that pregnancy in and of itself is not a contraindication to BD/death by neurologic criteria evaluation. Assess and diagnose pregnant patients with catastrophic, permanent brain injuries for BD/death by neurologic criteria.
A
Educate and discuss with surrogate decision-makers the risks and benefits to the fetus of continuing maternal organ support, assisted by clinicians knowledgeable in maternal-fetal medicine, child neurology, and neonatology as needed, after determining BD/death by neurologic criteria in a pregnant patient.
B

3.Patient education

Family support
Provide support and guidance for families as they face difficult end-of-life decisions for their loved one who has sustained a catastrophic brain injury. Ensure that communication is clear, concise, and supportive and includes simple terminology that families can understand. Provide appropriate emotional support for the family.
B
Ensure that hospital policies include consideration of providing a reasonable period to accommodate families after the death of a family member and provide a process to resolve disagreements when families do not agree with the medical team about the initiation of the BD/death by neurologic criteria evaluation and/or termination of organ support after determination of BD/death by neurologic criteria.
B

4.Follow-up and surveillance

Organ donation: consider discussing organ donation in all patients resuscitated from cardiac arrest and meeting neurological criteria for death.
B

5.Quality improvement

Health professional training: ensure that attending clinicians performing BD/death by neurologic criteria evaluation are appropriately credentialed members of the hospital medical personnel and adequately trained and competent in the evaluation of BD/death by neurologic criteria in pediatric or adult patients, as applicable (such as intensivists, neurologists, neurosurgeons) and in accordance with local laws and institutional standards.
