Abstract
Background
As more children survive with congenital heart disease, their neurodevelopmental outcomes
(including attention deficit hyperactivity disorder [ADHD]) are becoming increasingly
important. The objective of our study was to determine if school-aged children who
underwent early cardiac surgery for congenital heart disease are more likely than
healthy control subjects to have screening scores on the Swanson, Nolan, and Pelham
IV (SNAP-IV) questionnaire suggestive of ADHD.
Methods
Children aged 7-15 years who underwent open-heart surgery before 1 year of age were
identified from the Izaak Walton Killam (IWK) Children's Heart Centre Database. Control
subjects were recruited from healthy volunteers. The SNAP-IV questionnaire was administered
to all participants and a chart review was performed on all eligible children in the
cardiac surgery group. Case and control subjects were compared using Fisher's exact
test, linear, and logistic regression analyses. Potential predictors of a positive
screening score were sought.
Results
A positive screening score was found in 29% (16/56) of the surgical group compared
with 3% (2/60) of the control group (P < 0.001). Surgical and control subjects differed in average overall scores (0.93
vs 0.30; P < 0.001) and in scores for hyperactivity (0.83 vs 0.24; P < 0.001) and inattention (1.04 vs 0.37; P < 0.001). No other significant predictors of a positive screening score were identified.
The early open-heart surgery participants who responded to the questionnaire did not
differ in baseline characteristics compared with nonresponders.
Conclusions
Children who have open-heart surgery at younger than 1 year of age are more likely
than healthy control subjects to have a SNAP-IV score suggestive of ADHD when they
reach school age.
Résumé
Introduction
Puisque plus d’enfants survivent à la cardiopathie congénitale, leurs issues neurodéveloppementales
(incluant le trouble déficitaire de l’attention avec hyperactivité [TDAH]) sont devenues
de plus en plus importantes. L’objectif de notre étude était de déterminer si les
enfants d’âge scolaire qui avaient subi une chirurgie cardiaque précoce en raison
d’une cardiopathie congénitale étaient plus susceptibles que les témoins en santé
d’avoir des scores de dépistage au questionnaire SNAP-IV (Swanson, Nolan, and Pelham IV) évocateurs du TDAH.
Méthodes
Les enfants âgés de 7 à 15 ans qui avaient subi une chirurgie à cœur ouvert avant
l’âge de 1 an provenaient de la base de données de l'Izaak Walton Killam (IWK) (IWK Children’s Heart Centre : Centre de soins de santé cardiaque pour les enfants IWK). Les témoins ont été recrutés
parmi des volontaires en santé. Le questionnaire SNAP-IV a été effectué par tous les
participants et une étude des dossiers de tous les enfants admissibles au groupe de
chirurgie cardiaque a été réalisée. Les sujets malades et les témoins ont été comparés
à l’aide du test exact de Fisher, et des analyses de régression linéaire et de régression
logistique. Les prédicteurs potentiels d’un score de dépistage positif ont été recherchés.
Résultats
Un score de dépistage positif a été observé dans 29 % (16/56) du groupe de chirurgie
comparativement à 3 % (2/60) du groupe témoin (P < 0,001). Les sujets du groupe de chirurgie et les témoins ont différé dans les scores
moyens globaux (0,93 vs 0,30; P < 0,001) et dans les scores relatifs à l’hyperactivité (0,83 vs 0,24; P < 0,001) et à l’inattention (1,04 vs 0,37; P < 0,001). Aucun prédicteur significatif d’un score de dépistage positif n’a été déterminé.
Les participants ayant eu une chirurgie à cœur ouvert précoce qui avaient répondu
au questionnaire n’ont pas différé sur le plan des caractéristiques initiales comparativement
aux non-répondants.
Conclusions
Les enfants qui ont une chirurgie à cœur ouvert avant l’âge de 1 an sont plus susceptibles
que les témoins en santé d’avoir un score au SNAP-IV évocateur du TDAH lorsqu’ils
atteignent l’âge scolaire.
