Methods	A cohort study with 2 study samples (N = 60 and N = 30) where participants were part of a 6‐month audit regarding the use of methylphenidate and to determine if the NICE guidelines were followed
Participants	Number of participants screened: 420 Number of participants included: 90 Number of participants followed up: not stated Number of withdrawals: not stated Sex: 85 males, 5 females Diagnosis of ADHD: DSM‐IV (subtype: not stated) Age: mean 10 years old IQ: none with intellectual disability Methylphenidate‐naïve: not stated Ethnicity: not stated Country: UK Setting: not stated Comorbidity: 28.8% general learning difficulties, 21% sleeping problems, 28.8% mental health problems Comedication: not stated Sociodemographics: not stated Inclusion criteria: Children with a diagnosis of ADHD according to DSM‐IV who were prescribed MP after October 2000
Interventions	Methylphenidate dosage: most were treated with Ritalin Administration schedule: not stated Duration of intervention: 6 months Treatment compliance: not stated
Outcomes	Non‐serious adverse events: 12% reported side effects on methylphenidate, most were transient In 3 cases, medication was stopped due to side effects
Notes	Sample calculation: not stated Any withdrawals due to adverse events: for 3 patients the side effects resulted in medication stop. 2 patients stopped because of headaches and 1 because of hair loss Ethics approval: not stated Funding: none Vested interest/authors' affiliations: not stated Key conclusions of the study authors: the guidelines were followed, but not fully. However this was improved significantly in the second part due to increased professional awareness about ADHD because we held many seminars on this subject. The mental health team worked more closely than before with community paediatricians via joint ADHD clinics with child and adolescent psychiatrists. Families were getting better support via the ADHD family project which was jointly funded by health, education, and social services. The audits lead to a better provision of services for children with ADHD via specialist ADHD clinics Comments from the review authors: the reference was a poster, and no full text article has been published on the subject Exclusion of methylphenidate non‐responders/children who have previously experienced adverse events on methylphenidate: no Supplemental information regarding study information received through personal email correspondence with the authors in December 2013 (DeSoysa 2013 [pers comm])
