Mental health nurses must work with psychiatrists and GPs to provide services like monitoring a patient’s mental state, managing their medication and improving links to other health professionals and clinical service providers. A minimum of two patients must be seen per session, and evaluations seem to suggest that the programme has been quite succesful. Increased and/or improved training and continuing professional development (CPD) and use of evidence-based guidelines in primary care have the potential to be a cost-effective way to narrow some of the treatment gap for common disorders, and improve quality of care. In some OECD countries mental health training is included as part of their continuing professional development training.
