Abstract
Growth problems are prevalent among infants with congenital heart disease. We sought to determine whether frequency of outpatient clinic visits correlated with weight gain in patients with hypoplastic left heart syndrome or variant during the interstage period between discharge from stage I palliation and presentation for stage II palliation (SIIP). Using prospectively collected data from the JCCHD NPC-QIC database from June 2008 to July 2013, we performed a retrospective cohort study assessing the association of days between clinic visits (DBV) with the change in weight-for-age z-score (WAZ) during the interstage period. Eligible subjects were those who survived to a SIIP performed at <270 days of age and had at least two outpatient clinic visits. There were 561 patients from 49 centers who fulfilled inclusion criteria. The average interstage change in WAZ was +0.22. The mean number of DBV was 16.1 days, and the average number of clinic visits was six. There was no correlation of change in WAZ with either DBV (r = 0.02, P = 0.62) or the number of visits (r = 0.03, P = 0.44). Subjects within this cohort are seen about every 2 weeks averaged over the interstage period. There is no correlation between interstage visit frequency and change in WAZ in this patient population. Further research is needed to describe differences in visit frequency as the patient progresses through the interstage period and to elucidate whether patient factors such as growth velocity are influencing visit frequency. The optimal visit frequency remains unknown.
