Overestimating Neurodevelopment Using the Bayley-III After Early Complex Cardiac Surgery
BACKGROUND : The newest measure of neurodevelopmental outcomes , the Bayley Scales of Infant and Toddler Development , 3rd Edition ( Bayley-III ) , gives higher-than-expected scores for preterm infants ; results after cardiac surgery are unknown . OBJECTIVES : The goal of this study was to report Bayley-III scores after cardiac surgery and compare the results with those of the Bayley Scales of Infant Development , 2nd Edition ( BSID-II ) on a subset of the same children . METHODS : In this prospect i ve , inception cohort , neurodevelopmental outcome study after complex cardiac surgery in infants from 2004 to 2007 , the Bayley-III was given to 110 survivors ( 68 % boys ) at a mean age of 21 months ( SD : 4 months ) . Analysis of variance was used to compare intergroup differences . Results for both test editions on the same 25 children were compared by using paired- sample s statistics . RESULTS : Mean ( SD ) Bayley-III mean composite scores ( CSs ) for 110 children were as follows : cognitive , 95.9 ( 14.1 ) ; language , 90.8 ( 18.1 ) ; and motor , 93.7 ( 14.2 ) , differentiating selected cardiac surgery groups . The average difference in mean CSs was 7.4 points higher than BSID-II scores for a previous cohort from this site and 7.2 points higher than a systematic review report . Direct comparison of BSID-II and Bayley-III revealed an average difference in mean CSs of 6.1 points , similar to normative results . Mean cognitive CSs increased by 10.0 ( P < .001 ) , language by 1.4 ( P = .526 ) , and motor by 6.9 points ( P = .009 ) . CONCLUSIONS : Research ers should be careful attributing higher Bayley-III scores to changes in acute care . At-risk children who previously qualified for early developmental intervention may no longer do so . School-age longitudinal studies are needed to determine the accuracy of early developmental estimates using the Bayley-III
