Sociodemographic and clinical factors were compared between infants who died following WWLST and without WWLST.Results Of 1168 deaths, 67.1% occurred following WWLST. Withdrawal of assisted ventilation (97.4%) was the primary modality. WWLST rates were inversely proportional to gestational age. Life-sustaining treatment was withheld or withdrawn more often for non-Hispanic white infants than for non-Hispanic black infants (72.7% vs 60.4%; 95% CI 1.00 to 1.92) or Hispanic infants (72.7% vs 67.2%; 95% CI 1.32 to 3.72). WWLST rates varied across centres (38.6–92.6%; p<0.001). The centre with the highest rate had adjusted odds 4.89 times greater than the average (95% CI 1.18 to 20.18). The adjusted odds of WWLST were higher for infants with necrotiing enterocolitis (OR 1.77, 95% CI 1.21 to 2.59) and severe brain injury (OR 1.98, 95% CI 1.44 to 2.74).Conclusions Among infants who died, WWLST rates varied widely across centres and were associated with gestational age, race, ethnicity, necrotiing enterocolitis, and severe brain injury. Further exploration is needed into how race, centre, and approaches to care of infants with necrotiing enterocolitis and severe brain injury influence WWLST.Data reported in this paper may be requested through a data use agreement.
