To understand neonatologists' attitudes toward end-of-life (EOL) management in clinical scenarios, EOL ethical concepts and resource utilization. American Academy of Pediatrics (AAP) Perinatal section members completed an anonymous online survey. Respondents indicated preferences in limiting life-sustaining treatments in four clinical scenarios, ranked agreement with EOL-care ethics statements, indicated outside resources previously used and provided demographic information. In all, 451 surveys were analyzed. Across clinical scenarios and as general ethical concepts, withdrawal of mechanical ventilation in severely affected patients was most accepted by respondents; withdrawal of artificial nutrition and hydration was least accepted. One-third of neonatologists did not agree that non-initiation of treatment is ethically equivalent to withdrawal. Around 20% of neonatologists would not defer care if uncomfortable with a parent's request. Respondents' resources included ethics committees, AAP guidelines and legal counsel/courts. Challenges to providing just, unified EOL care strategies are discussed, including deferring care, limiting artificial nutrition/hydration and conditions surrounding ventilator withdrawal.
