RT Journal Article SR Electronic T1 Decision-making at the border of viability: determining the best interests of extremely preterm infants JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 773 OP 779 DO 10.1136/medethics-2019-105816 VO 46 IS 11 A1 Eric Vogelstein YR 2020 UL http://jme.bmj.com/content/46/11/773.abstract AB This paper proposes and employs a framework for determining whether life-saving treatment at birth is in the best interests of extremely preterm infants, given uncertainty about the outcome of such a choice. It argues that given relevant data and plausible assumptions about the well-being of babies with various outcomes, it is typically in the best interests of even the youngest preterm infants—those born at 22 weeks gestational age—to receive life-saving treatment at birth.
