Abstract

Background: The World Health Organization recommends that treatment of tuberculosis (TB) in HIV-infected patients should be integrated with HIV care. In December 2008, a separate outdo-orintegrated TB/HIV clinic was instituted for attendees of a large urban HIV clinic in Uganda. We sought to evaluate associated TB and HIV treatment outcomes. Methods: Routinely collected clinical, pharmacy, and laboratory data were merged with TB clinic data for patients initiating TB treatment in 2009 and with TB register data for patients in 2007. TB treatment outcomes and (timing of) antiretroviral therapy (ART) initiation in ART-naive patients [overall and stratified by CD4+ T cell (CD4) count] in 2007 and 2009 were compared. Nosocomial transmission rates could not be assessed. Results: Three hundred forty-six patients were initiated on TB treatment in 2007 and 366 in 2009. Median CD4 counts at TB diagnosis did not differ. TB treatment cure or completion increased from 62% to 68%, death or default decreased from 33% to 25% (P<0.001). Fewer ART-naive TB patients were initiated on ART in 2009 versus 2007 (57% and 66%, P = 0.031), but this decrease was only in patients with CD4 counts>250 cells per cubic millimeter (19% vs. 48%, P = 0.003). More patients were started on ART during TB treatment (94% vs. 78%, P<0.001). Moreover, the majority were now initiated during intensive phase (60% vs. 23%, P<0.001). Conclusions: Integration of TB and HIV care has led to improved TB treatment outcomes and earlier, prioritized ART initiation. This supports rollout of a fully integrated TB/HIV service delivery model throughout high-prevalence TB and HIV settings.
