Health technology assessment and gastroenterology.
Too much clinical practice is based on unproved opinion. Health technology assessment (HTA) encourages critical review of the literature in a particular area, from which an objective assessment can be made so that clinical practice may be more scientifically based. Only a small number of centers undertake this type of work, usually at a national level. We have been able to set up a more local HTA system (the Wessex Development and Evaluation Committee) with links to clinicians and both providers and purchasers of health care within a region of 3 million people. All aspects of medicine may be reviewed and discussed by the committee; 3 examples from within the field of gastroenterology are summarized herein. Active participation of a university-based institute to provide the reviews is essential. A local HTA facility confers a number of advantages.
