Impact of pharmacotherapy on interstage mortality and weight gain in children with single ventricle
Abstract
OBJECTIVE.: Infants with single ventricle physiology have a high mortality and poor somatic growth during the interstage period. We retrospectively assessed the impact of pharmacotherapy in this population using a multicenter database. DESIGN AND RESULTS.: Records for 395 patients (63.5% boys) with single ventricle were obtained from the National Pediatric Cardiology Quality Improvement Collaborative registry. Median of five medications were prescribed per patient at discharge after stage 1 palliation (interquartile range 3 to 6); the most common medications being aspirin (95.7%), diuretics (90.4%), angiotensin convertase enzyme inhibitors (37.7%), proton pump inhibitors (33.4%), H2 receptor blockers (30.6%), and digoxin (27.6%). Interstage mortality was 9.4%. Digoxin use was associated with lower risk of death (P =.03) on univariable analysis, however no single medication was an independent predictor on regression analysis. Change in weight-for-age z-score was studied as outcome of somatic growth with 36.3% patients showing a decrease during the interstage period. Total number of medications prescribed to a patient showed a negative correlation with the interstage change in z-score (r = -0.19, P =.002). On univariable comparisons, use of metoclopramide and lansoprazole were associated with decreased z-score (P =.004 and.041, respectively) although linear regression failed to identify any agent as independent predictor. CONCLUSIONS.: Children with single ventricle have high…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 395 participants or records.
