Abstract

Objective

To document patient characteristics and treatment patterns in a real-world population diagnosed with attention-deficit/hyperactivity disorder (ADHD).

Methods

This was a retrospective chart review of children/adolescents (6–17 years) diagnosed with ADHD in the UK, Germany and Netherlands who initiated stimulant monotherapy (SM), non-stimulant (atomoxetine) monotherapy (NSM) or polypharmacy (SM/NSM ± SM/NSM or other psychotropics) on/after 1-1-2012. To facilitate descriptive comparisons, cohort quotas were imposed: ∼50% SM; ∼25% NSM; ∼25% polypharmacy. Index date was first SM, NSM or polypharmacy treatment on/after 1-1-2012. Patients were required to have ≥ 6 months’ pre-index (baseline) history and ≥ 12 months’ post-index follow-up. Analyses were descriptive.

Results

In total, 497 patients were included (mean [SD] age: 10.8 [2.9] years; 77% male); 65% (SM), 63% (NSM) and 83% (polypharmacy) had at least marked baseline ADHD severity based on Clinical Global Impressions scale (P < 0.05 SM/NSM vs polypharmacy). Ninety percent (SM), 75% (NSM) and 73% (polypharmacy) were pharmacotherapy naïve at index (all P < 0.10); 61% (SM), 65% (NSM) and 72% (polypharmacy) received previous behavioural therapy. In SM patients, methylphenidate was predominant (most frequent brands: Concerta® [29%], Medikinet® [28%]); in polypharmacy patients, methylphenidate plus atomoxetine (22%) or other psychotropic (19%) was most common. Index therapy switch was common, particularly in polypharmacy patients (25%) (P < 0.05 vs SM [14%] and NSM [13%]). Switches were precipitated by poor response in 75% of cases overall.

Conclusions

Polypharmacy patients generally presented a more complicated history (including higher ADHD severity) and treatment pathway versus monotherapy patients. Index therapy switches were commonplace and more frequent in polypharmacy patients, often due to poor response.
