1 ADHD Medication Prescribing in Scotland in 2016/17 Scottish ADHD Coalition Analysis March

2 Notes on data sources Prescribing data was obtained through a data request to ISD Scotland to add more detail by age and Health Board, based on their publication Medicines used in Mental Health 2016/17 These were analysed by the Scottish ADHD Coalition against the Mid Year Population Estimates for Scotland by age and NHS Health Board 2016 (National Records of Scotland) Notes: Data is based on British National Formulary (BNF) March 2015 for section 4.4 (medicines for ADHD), excluding Modafinil (which is exclusively for the treatment of narcolepsy). It is possible that some ADHD medications are prescribed for people with other diagnoses than ADHD. However, this is very rare except in the very elderly population. The number of people taking ADHD medication is only a proxy for the rate of diagnosis. It is not known what proportion of people with ADHD are taking medication, but a recent survey by the Scottish ADHD Coalition of parents showed that 88% of parents of children with confirmed ADHD reported that their child was taking an ADHD medication currently (n=214 respondents). The proportion of adults with diagnosed ADHD taking medication may be much lower. Individual patients prescribed ADHD medication were identified by CHI number (the unique identifier assigned to each NHS patient in Scotland). Island Health Boards and children below the age of 6 are excluded from the analyses due to very small numbers.
