Scientific titleThe Zambia, South Africa, Tuberculosis and Acquired Immune Deficiency Syndrome-reduction Trial
Study acronymZAMSTAR
Study objectivesTwo new approaches to improving case detection of tuberculosis in communities with a high burden of tuberculosis and human immunodeficiency virus (HIV) are able to reduce the prevalence of tuberculosis (TB) at a community level over a three year period
Ethics approval(s)Approved by the London School of Hygiene and Tropical Medicine on 14/03/05, reference number: 3008; approved by the University of Zambia on 15/12/04 and also approved by the University of Stellenbosch on 18/01/05 reference number: N04/10/173
Health condition(s) or problem(s) studiedTuberculosis
InterventionThe two interventions are:
1. Improved case finding: by allowing individuals direct access to diagnostic services and empowering communities to seek care, we will bypass the health system barriers and greatly reduce the number of people who are spreading infection
2. Integrated TB/HIV care delivered through the household: by harnessing the capacity of households and the community we will reduce the burden on the health system, increase the coverage and efficiency of preventive and curative tuberculosis services and break down the barriers of stigma and denial

The two interventions described are divided equally among the 24 randomised communities: six will receive both, another six will receive improved case finding only, another six will receive integrated TB/HIV care delivered through the household and another six will receive neither.
All communities benefit from support to the general health service to improve routine TB/HIV activities that are not part of either interventions.
Intervention typeOther
Primary outcome measureThe primary outcome will be the prevalence of culture-positive tuberculosis among a randomly selected population of adults in each arm of the trial, measured after 3 years of the interventions
Secondary outcome measuresSecondary outcomes measured at the community level include:
1. Cumulative incidence of tuberculosis infection in school children
2. Indicators of tuberculosis and HIV programme performance

At the household level, they include:
1. Cumulative incidence of tuberculosis
2. Changes in HIV incidence and stigma
