Abstract

Objective: Interstage readmissions are common in infants with single ventricle congenital heart disease undergoing staged surgical palliation. We retrospectively examined readmissions during the interstage period.
Design: Retrospective analysis.
Setting: The Heart Center at Nationwide Children’s Hospital, Columbus, Ohio.
Patients: Newborns undergoing hybrid stage 1 palliation from January 2012 to December 2016 who survived to hospital discharge and were followed at our institution.
Interventions: All patients underwent hybrid stage 1 palliation.
Outcome Measures: Outcomes included (1) reason for interstage readmission; (2) feeding modality during interstage period; (3) major interstage adverse events; and (4) interstage mortality.
Results: Study group comprised 57 patients. Five patients only admitted once during the interstage period for scheduled cardiac catheterization were included in the no readmission group. Therefore, 43 patients (75%) had a total of 87 interstage readmissions. Fourteen patients had 15 major interstage adverse events accounting for 17% of total readmissions. Stroke (n = 1); sepsis (n = 1); pericardial effusion requiring drainage (n = 1); mesenteric ischemia (n = 1); shock (n = 1); and cardiac catheterization requiring intervention (n = 11)— ductal stent balloon angioplasty (n = 3), enlargement of atrial septal defect/stent placement (n = 3), retrograde aortic arch stenosis (n = 4). Thirty‐three readmissions were secondary to gastrointestinal/feeding issues; 15 cyanosis; 15 work of breathing; and 9 asymptomatic patients. Four patients suffered interstage deaths (7%). Five patients (9%) spent >30 days in the hospital during the interstage period. Of the 47 newborns (82%) discharged exclusively orally feeding, 74% remained all orally feeding throughout interstage period. No patient discharged with tube feedings learned to eat during the interstage period.
Conclusion: Interstage readmissions are common in the hybrid patient population. Seventeen percent were secondary to major adverse events. Interstage mortality was 7%. Future studies to identify interventions aimed at decreasing feeding issues and viral bronchiolitis in this tenuous patient population will hopefully improve ­quality outcomes, reduce readmissions, and lessen health care costs.
