Background:
This paper presents the methods and findings of a survey of current service configuration in tuberculosis screening, treatment and prevention in England and Wales, which was conducted as part of the development of the National Institute for Health and Clinical Excellence guidelines on tuberculosis for the country.
Methods:
A random sample of health protection units (HPUs) was surveyed (stratified geographically) in England. For Wales, National Health Service boundaries were used. There was a 100% sample of HPUs (33 clinics) in London and a 50% sample (81 clinics) outside London. The survey was completed by nurses in tuberculosis clinics. The questionnaire asked for details of caseload in terms of active disease (notified cases) and latent infection (screening and chemoprophylaxis), and the different types of specialist tuberculosis services offered.
Results:
Completed surveys were obtained from 67 of 81 clinics outside London and all 33 clinics in London. An association was found between the number of notifications and personnel, in line with previous British Thoracic Society guidelines. Higher notification areas, especially in London, provide additional specialist services such as human immunodeficiency virus/tuberculosis clinics and specialist paediatric clinics. Clinics in London also reported higher usage of incentives, directly observed therapy (DOT) and free prescriptions. Low notification areas outside London tend to see more patients at home for contact tracing and treatment review. However, there is considerable variation in the use of DOT and chemoprophylaxis that is not entirely explained by differences in caseload.
Conclusions:
The survey showed that service configuration was organized in different ways in both high and low incidence areas. There is a need to share good practice and explore ways to configure services effectively in line with local needs.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
