This audit aims to compare UK management of tuberculosis (TB)/HIV co-infection with recommended practice and to describe local care arrangements. Services providing HIV care were invited to complete a survey of care arrangements and to review case notes of HIV positive patients aged over 16 who started therapy for active TB between October 2007 and April 2008. Corresponding TB services, if separate, were invited to complete a similar survey. Responses were received from 124 of 170 HIV services, and 18 corresponding TB services. Data were obtained for 236 coinfected patients. Despite some incomplete data, this audit yielded useful findings. Many positive smear results were unacceptably delayed. The TB therapy completion rate fell short of the chief medical officer's (CMO's) 85% target. Culture confirmation of pulmonary TB met the CMO's 65% target. A high number of patients were diagnosed with HIV during investigation of TB. Contrary to current guidelines, many services do not routinely test TB patients for HIV.
