The Royal College of Psychiatrists (RCPsych) has formulated “Attention Deficit-Hyperactive Disorder (ADHD) in Adults: Good Practice Guidelines” to provide evidence-based guidance for clinicians, acknowledging there is an increasing burden on the services with the assessment and management of adult ADHD in the United Kingdom. As there is no trust-wide policy in North Wales and some practitioners perceive that it is challenging to perform an extensive assessment for ADHD in the adult secondary mental health services, there is a need to study the pre-referral workup and diagnostic approach for patients referred to the adult mental health services. This clinical audit is aimed at understanding the guideline adherence level of the assessment and management of adult ADHD by both primary and secondary mental health services in Betsi Cadwaladr University Health Board.

Convenient sampling was performed on 50 patients from three community mental health teams (CMHT) from East of North Wales for patients with a confirmed diagnosis of adult ADHD. The source of information included referrals from the primary care (including general practitioners and primary mental health service) and medical records from the secondary mental health care. Relevant clinical information was collected and coded as “present”, “absent”, or “unclear”. The data were compared to the standard derived from “ADHD in adults: Good practice guidelines”.

Only 34% of the referrals documented the use of Adult ADHD Self-Report Scale, 18% documented the use of Autism Spectrum Quotient (AQ-10), and none documented the use of Weiss Functional Impairment Rating Scale (W-FIRS).

Only 46% of patients was diagnosed using a standardised instrument after more than one session of diagnostic assessment. The percentage of documentation of baseline blood pressure, pulse rate, weight, and height were 58%, 70%, 50%, and 44% respectively.

Most documentations fell below 50%, including comorbid and family history of physical health conditions, history of neurodevelopmental issues, and corroborative history. All teams performed well with the documentation of functional impairment, comorbid anxiety disorder, depressive disorder, and substance use disorder, i.e., >90% of patients.

This audit reflects the need for quality improvement in documentation in both primary and secondary care settings although the solution should not add to the existing burden of practitioners. Convenient sampling from East of North Wales limits the generalisability of findings. Also, the absence of data may be contributed by logistic issues around paper-based medical records, i.e., illegible handwriting and inability to locate the documentation.
