Clinical Course for Patients With Trisomy 13 and 18 Pursuing Life-Prolonging Therapies Versus Comfort-Directed Care

Background: Care for infants with Trisomy 13 and 18 is evolving with more children being offered medical and surgical interventions. Parents and clinicians of children diagnosed with trisomy 13 and 18 would benefit from understanding how parental goals of care correlate with the subsequent clinical course of children with these conditions. Objective: To describe and compare parental goals of care (GOC) and clinical course in infants with trisomy 13 and 18. Design: Single center, retrospective (2013-19) analysis of electronic health record repository at a birthing center and a tertiary care hospital. Measurements: ICD-9/10 codes were used to identify patients with trisomy 13 or 18 born between 2013-2019. Their records were abstracted for their diagnosis, hospitalization days, interventions, GOC, death location and length of life. Result: Twenty-eight total patients were identified; trisomy 13, mosaic trisomy 13 and trisomy 18 were diagnosed in 9, 2 and 17 patients respectively. Among the 26 patients with complete trisomy 13 or 18, 8 had life-prolonging and 18 had comfort care goals at birth/diagnosis. Life-prolonging goals were not associated with longer life (p = 0.36) but were associated with more mean hospital days (70 vs. 12, p = 0.01), ICU days (66 vs. 9, p = 0.009), intubation (7/8 vs 7/18, p = 0.04), and death in ICU (7/7 vs. 10/17, p = 0.02). Zero patients underwent cardiac surgery. Conclusion: Parental GOC did not affect length of life in children with complete trisomy, but did alter treatment intensity. This may inform decision making for patients with trisomy 13 or 18.
