Insights
Parental goals of care for infants with Trisomy 13 and 18 did not impact lifespan but significantly influenced treatment intensity, including hospital and ICU days. This finding can guide clinical decision-making for these complex genetic conditions.
Area of Science:
- Genetics and Developmental Biology
- Pediatric Medicine
- Palliative Care
Background:
- Care for infants with Trisomy 13 and 18 is advancing with increased medical and surgical options.
- Understanding the link between parental goals of care and clinical outcomes is crucial for informed decision-making.
Purpose of the Study:
- To describe and compare parental goals of care (GOC) with the clinical course of infants diagnosed with Trisomy 13 and 18.
- To analyze the impact of GOC on treatment intensity and survival in these infants.
Main Methods:
- Retrospective analysis of 28 infants diagnosed with Trisomy 13 or 18 between 2013-2019 at a single center.
- Electronic health records were reviewed for diagnoses, hospitalization duration, interventions, GOC, and survival data.
Main Results:
- Among 26 infants with complete Trisomy 13 or 18, 8 had life-prolonging goals and 18 had comfort care goals.
- Life-prolonging GOC was associated with increased hospital days (70 vs. 12), ICU days (66 vs. 9), intubation rates, and in-ICU deaths.
- No significant difference in length of life was observed between groups (p = 0.36).
Conclusions:
- Parental GOC significantly influences treatment intensity but not the length of life for infants with complete Trisomy 13 or 18.
- These findings can aid clinicians and families in navigating complex care decisions for these conditions.
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.
