The South West Thames Regional Health Authority approach to the method of audit in public health medicine.

Following the Faculty Training Conference on Audit in March 1990, South West Thames Region set up a Working Group to develop a framework for audit in Public Health Medicine that could be adopted across the Region. This paper outlines the methodology used by the Working Group, introducing the concept of an 'Audit Tree', and describes how audit in Public Health Medicine can be approached using such a model.
