Implementation of tuberculosis infection control measures at HIV care and treatment sites in sub-Saharan Africa.

SETTING: A total of 663 human immunodeficiency virus (HIV) care and treatment sites in nine tuberculosis (TB) affected African countries serving over 900000 persons living with HIV. OBJECTIVE: To determine the implementation of infection control (IC) measures and whether program and facility characteristics were associated with implementation of these measures. DESIGN: A survey was conducted to assess the presence of a TB IC plan triage practices for TB suspects location of sputum collection and availability of particulate respirators. The association of facility characteristics with IC measures was examined using bivariate and multivariate methods. RESULTS: Forty-seven per cent (range across countries [RAC] 2-77%) of sites had written TB IC plans; 60% (RAC 5-93%) practiced triage; of those with access to microscopy 83% (RAC 59-91%) performed sputum collection outdoors and 13% (RAC 0-36%) in ventilated indoor rooms; 16% (RAC 1-87%) had particulate respirators available. Sites providing anti-tuberculosis treatment were more likely to have written IC plans (54% vs. 12% P < 0.0001) and particulate respirators (18% vs. 8% P = 0.0126) and to perform TB triage (65% vs. 40% P = 0.0001) than those without anti-tuberculosis treatment services. CONCLUSIONS: To protect HIV-infected patients and health care workers there is an urgent need to scale up IC practices at HIV care and treatment sites particularly at sites without anti-tuberculosis treatment services.
