Implementation of treatment guidelines for specialist mental health care.

A huge gap exists between the production of evidence and its uptake in clinical practice settings. To fill this gap, treatment guidelines, based on explicit assessments of the evidence base, are commonly used in several fields of psychiatry, including schizophrenia and related psychotic disorders. However, it remains unclear whether treatment guidelines have any material impact on provider performance and patient outcomes, and how implementation should be conducted to maximise benefit.
