Non-medical prescribing is increasingly utilized in clinical care and UK Standards have been produced for this. This study was undertaken to investigate compliance with these standards which were adopted by one mental health service and to review whether any changes were necessary to existing arrangements monitoring this compliance. A questionnaire was distributed to all 24 non-medical prescribers from one UK Mental Health Trust. Participants were asked to respond to questions about demographic data and prescribing practices. We also asked them to rate their experience on a 5-point scale. In all, 83% of non-medical prescribers responded. The UK Standards were met even though there was a shortfall in the uptake of training and supervision. Non-medical prescribers from the Community Drug Team and Older People's Service prescribed a narrow range of speciality drugs than any other category of drugs, but prescribed more often. UK Standards were met by the majority of non-medical prescribers. However, concerns were noted about a shortfall in training, supervision and experience of some non-medical prescribers. Conflict with psychiatrists was reported but their availability for support when necessary was valued. Non-medical prescribers believed that their input with non-medical prescribing had benefited patients.
