The influence of type of consultation and patient characteristics on non-attendence at adult ADHD consultation.

AIMS AND METHOD: Non-attendance at out-patient appointments of adult attention-deficit hyperactivity disorder (ADHD) services incurs significant costs and contributes to lost service provision and unmet clinical needs. This cross-sectional study of clinical contacts, between 1 July 2022 and 30 June 2023 in a specialist adult ADHD service, aimed to identify factors, including type of consultation, associated with non-attendance.

RESULTS

Of 3673 organised clinic appointments, 2815 (77%) were attended: 2314 (82%) by telephone and 501 (18%) as in-person appointments; non-attendance rates were 17 and 42%, respectively. Patient characteristics associated with improved attendance included: female gender, age >30 years and presence of other psychiatric diagnoses.

CLINICAL IMPLICATIONS: This study will assist adult ADHD service providers to maximise patient attendance. The role of telephone (or virtual) clinics must be considered. Enhanced appointment reminders and improving access to services targeting at-risk groups could also improve attendance rates.
