    Abstract:
    OBJECTIVE: To evaluate the impact of the American Heart Association (AHA) scientific statement regarding electrocardiograms (ECGs) and stimulant medications on the practice of community pediatricians. DESIGN: Retrospective evaluation and survey analysis. SETTING: Academic tertiary care center. PARTICIPANTS: Patients with ECGs referred to our institution by pediatricians with an indication of stimulant medication screening in the year after the AHA statement. INTERVENTION: We compared the ECG ordering practices of community pediatricians and the outcomes of further evaluation and estimated the associated cost before and after the AHA scientific statement. MAIN OUTCOME MEASURES: Abnormal ECG findings, further workup, and change in clinical practice. RESULTS: In the year after publication of the 2008 AHA scientific statement, 372 ECGs were ordered with an indication of stimulant medication screening. Before publication of this statement, a mean (SD) of 6.9 (3.2) ECGs per month were referred for this indication. Despite continuing controversy, this number increased 4-fold to 31.2 (9.5) ECGs per month in the subsequent year. Twenty-four ECGs (6.4%) had abnormal findings. Eighteen patients were referred for further evaluation, and, at last follow-up, none had been found to have definitive disease. Six of 24 patients with abnormal ECG findings (25.0%) had a perceived significant delay in therapy because of the process. In responding pediatricians, 34.6% reported that the scientific statement had clearly affected their practice. CONCLUSIONS: The clinical practice of community pediatricians in regard to screening ECGs and stimulant medications has been affected by the recent AHA scientific statement. The yield of performing ECGs with an indication of stimulant medication screening is very low.
