Abstract

This retrospective study assessed the benefits and risks of discontinuation of pharmacological treatment during summer holidays (? 30 days) in 802 school-aged children with attention deficit/hyperactivity disorder (ADHD). A total of 440 patients (55%) discontinued medical treatment during the summertime. The risk of poor adherence (? 85%) was higher for patients with drug holidays (odds ratio 5.82). As compared with children treated pharmacologically during the summertime, patients in the drug holiday group were four times more likely to have worsening or no improvement of their symptoms in the Clinical Global Impression ADHD Severity (GCIADHD- S) scale (odds ratio 4.20, P < 0.0001). Moreover, patients in the drug holiday group as compared with patients treated pharmacologically were almost three times more likely to score > 1.67 in the ADHD SNAP-IV rating scale (odds ratio 2.60, P < 0.0001), and more likely to suffer from accidental injuries (odds ratio 1.49, P < 0.01), with a higher mean number of injuries per patient (1.24 [SD = 3.67] vs. 0.8 [SD = 2.9], P = 0.05). This retrospective cohort analyses suggest that drug holidays during the summertime in children with ADHD may be associated with adverse clinical outcomes.
