Evidence-based mental health policy: a critical appraisal
Abstract
Background: Arguments for and against evidence-based psychiatry have mostly centred on its value for clinical practice and teaching. Now, however, use of the same paradigm in evaluating health care has generated new problems.
Aims: To outline the development of evidence-based health care; to summarise the main critiques of this approach; to review the evidence now being employed to evaluate mental health care; and to consider how the evidence base might be improved.
Method: The following sources were monitored: publications on evidence-based psychiatry and health care since 1990; reports of randomised trials and meta-analytic reviews to the end of 2002; and official British publications on mental health policy.
Results: Although evidence-based health care is now being promulgated as a rational basis for mental health planning in Britain, its contributions to service evaluation have been distinctly modest. Only 10% of clinical trials and meta-analyses have been focused on effectiveness of services, and many reviews proved inconclusive.
Conclusions: The current evidence-based approach is overly reliant on meta-analytic reviews, and is more applicable to specific treatments than to the care agencies that control their delivery. A much broader evidence base is called for, extending to studies in primary health care and the evaluation of preventive techniques.
