OBJECTIVE: This study aims to characterize population risks for diagnosis, medical treatment, and surgical ligation of patent ductus arteriosus (PDA) in very low-birth-weight infants.
STUDY DESIGN: Maternal and neonatal data were collected in 40 hospitals in California during 2011 for infants with birth weight ≤ 1,500 g without any congenital malformation, with a diagnosis of PDA. Multivariable logistic regression was used to determine independent risks for PDA diagnosis and for surgical ligation.
RESULTS: There were 770/1,902 (40.4%) infants diagnosed with PDA. Low birth weight, gestational age, respiratory distress syndrome, and surfactant administration were associated with PDA diagnosis. Ligation occurred in 43% of patients with birth weight ≤ 750 g, in 24% of patients weighing between 715 and 1,000 g, and in 12% of patients weighing from 1,001 to 1,500 g. Older gestational age (1 week, odds ratio 0.55, 95% confidence interval 0.48-0.63) and absence of respiratory distress syndrome (odds ratio 0.14, 95% confidence interval 0.03-0.59) were associated with lower ligation risk. The median hospital ligation rate was 14% (interquartile range 0-38%).
CONCLUSION: Most patients with PDA receive treatment for closure. Practice variation may set the stage for further exploration of experimental trials.
