Evaluation of collaborative tuberculosis and human immunodeficiency virus activities in Phnom Penh, Cambodia.

SETTING

Phnom Penh, Cambodia.

OBJECTIVES

1. To monitor the number of tuberculosis (TB) patients undergoing human immunodeficiency (HIV) testing during TB treatment and trends of referral of TB-HIV patients to HIV services following the appointment of TB-HIV coordinators in TB wards, and 2) to investigate factors that influence undesirable TB treatment outcomes.

DESIGN

Retrospective descriptive study based on a review of patient records and interviews with programme staff.

RESULTS

Eighty-six per cent of newly registered TB patients underwent HIV testing. Most of the TB-HIV patients were referred to HIV services. Using logistic regression analysis, the risk of an undesirable treatment outcome in extra-pulmonary TB was significantly lower than in smear-positive pulmonary TB. Interviews revealed that patients in poor clinical condition at the start of TB treatment or who faced social problems, such as homelessness or foreign nationality, were at considerable risk for undesirable TB treatment outcomes.

CONCLUSION

The appointment of TB-HIV coordinators to TB wards resulted in better HIV testing uptake and referral to HIV care and treatment services. To save TB-HIV patients' lives, it is important to continue this kind of study over a longer term to monitor these activities and to identify high-risk patients.
