Twenty‐six of the 36 (72%) infants were small for gestational age (SGA).Ten of the 36 infants received compassionate care and died in the delivery or operating room. Twenty‐six of the 36 infants were admitted to the neonatal intensive care unit (NICU), of whom 12 (46%) died during their admission. At age 12 months corrected, 2/14 (14%) of survivors had none/minimal, 4/14 (29%) had mild and 8/14 (57%) had moderate/severe neurodevelopmental disability. Overall, the survival rate was 39%, and survival without neurodevelopmental disability was 6%. Only 1/10 appropriate‐for‐gestational‐age (AGA) infants survived to discharge (and had severe disability), whereas 13/26 (50%) of all SGA infants in the study survived to discharge. Of all infants admitted to the NICU, 11/26 (42%) survived without severe neurodevelopmental disability at latest follow‐up.</p> </sec> <sec id="jpc12414-sec-0004" sec-type="section"> <title>Conclusions</title> <p>There was a high risk of death or impairment in this cohort of infants.
