Kidszun A, Matheisl D, Tippmann S, et al. - Since it is unclear if probabilistic data affect the choices of parents in prognostic gray zones, researchers tested the assumption that estimates of better or worse neonatal outcome do not affect the life-sustaining treatment preferences of expectant mothers. Extremely preterm infants born before a gestational age of 25 weeks are in a prognostic gray zone, meaning the results are poor but not hopeless and life-sustaining treatments are not mandatory. Treatment decisions are value-laden and challenging and should be shared between parents and physicians while being aligned imperatively with parental preferences. Doctors commonly present numerical outcome estimates when counseling parents, and can assume that parents derive their preferences from them.
