Abstract
This thesis presents the results of three studies examining the management of migraine in children. First we conducted a systematic review of all clinical trials conducted in children and adolescents of the acute migraine therapy. A meta-analysis of the 26 randomized controlled trials is presented. A single trial with a focus on Emergency Department (ED) management was identified. As such, we then examined current ED practice in two retrospective practice variation studies. The first compared four regional hospital EDs where practice patterns were significantly different between mixed population EDs (both adult and pediatric patients) and the tertiary pediatric ED. The second examined practice variation among ten tertiary pediatric EDs in Canada where significant differences were again observed. Factors that influenced the choice of medications included increasing patient age and the physician’s diagnosis of migraine. Important areas of future investigation include: (1) the effectiveness of intravenous fluids alone; and (2) the use of combined medications.
