OBJECTIVE: To evaluate car seat tolerance screening failure rate in infants with CHD, clinical factors associated with test failure, and the impact of a failed test.
METHODS: Single-centre retrospective study of 193 infants with CHD discharged from a general cardiology service between November 2020 and November 2024. Characteristics were compared between patients who passed and failed car seat testing using Wilcoxon-Mann-Whitney tests for continuous variables, and chi-square or Fisher's exact tests for categorical variables.
RESULTS: Car seat test failure rate was 6.2% (12 of 193 patients). Neither median birthweight (3.2 kg vs. 3.3 kg, p = 0.68) nor the rate of prematurity (13.8% vs. 16.7%, p = 0.68) differed significantly between passing and failing groups. There was no relationship between cardiac physiology and car seat test failure (p = 0.39). There were no differences in rates of seizure (p = 0.29), stroke (p = 1.00), gastroesophageal reflux disease (p = 0.84), vocal cord dysfunction (p = 1.00), or pulmonary hypertension (p = 1.00) between passing and failing groups. Infants who failed had significantly higher rates of DiGeorge Syndrome (25.0%) compared to those who passed (2.2%) (p = 0.006). Readmission within 30 days of discharge was not different between failing (16.7%) and passing (17.1%) groups (p = 1.00). A failed test delayed discharge by a median of 1.5 days [IQR: 1.0-2.5 days].
CONCLUSION: The car seat test failure rate of our CHD cohort is higher than the published failure rate for premature infants. There was no relationship between cardiac physiology and test failure. DiGeorge Syndrome was the only comorbidity associated with increased failure rate. Failed car seat tests delay hospital discharge.
