The journey to antiretroviral therapy in Karnataka, India: Who was lost on the road?

Introduction: One important operational challenge facing antiretroviral treatment (ART) programmes in low- and middle-income countries is the loss to follow-up between diagnosis of human immunodeficiency virus (HIV) and initiation of ART. This is a major obstacle to achieving universal access to ART. This study from Karnataka, India, tried to measure such losses by determining the number of HIV-positive individuals diagnosed, the number of them reaching ART centres, the number initiated on ART and the reasons for non-initiation of ART. Methods: A review of records routinely maintained under the National AIDS Control Programme (NACP) was carried out in six districts of Karnataka. HIV-positive persons diagnosed during the months from January to June 2011 in 233 public HIV-testing sites were followed up until December 2011 based on the pre-ART registers. A chi-square test was used to assess statistical significance. Results: Of 2291 HIV-positive persons diagnosed (52% male; mean age of 35 years), 1829 (80%) reached ART centres. Of the latter, 1166 (64%) were eligible for ART, and 959 (82%) were initiated on treatment. Overall losses (attrition) on the road between HIV diagnosis and ART initiation were 669 (29%). Deaths, migration and not willing to go to the ART centres were cited as the main known reasons for not reaching ART centres. For ART-eligible individuals who did not initiate ART, the most common known reasons for non-initiation included dying before initiation of ART and not being willing to start ART. Conclusions: In a large state of India, eight in ten HIV-positive persons reached ART centres, and of those found ART eligible, 82% start treatment. Although this is an encouraging achievement, the programme needs to take further steps to improve the current performance by further reducing pre-ART attrition.We recommend online registering of diagnosed HIV-positive patients to track the patients more efficiently.
