SettingFour primary health care clinics providing tuberculosis (TB) and Human Immunodeficiency Virus care services in Bulawayo, Zimbabwe.ObjectivesTo assess isoniazid preventive therapy (IPT) initiation and completion, factors associated with IPT uptake and incidence of TB, and TB and antiretroviral treatment (ART) outcomes among people living with HIV (PLHIV).DesignThis was a cohort study using routine data in the records for PLHIV initiated on ART from October 2013 to March 2014 with 31 December 2017 as the end of the follow-up period.ResultsA total of 408 PLHIV were eligible for IPT, 214 (52%) were initiated on IPT and 201 (94%) completed IPT. No person in the IPT-initiated group developed Tuberculosis (TB). Six persons with TB were reported among the non-IPT-initiated group leading to an incidence of 9 cases/1,000 person-years of follow-up. About 70% of those who developed and were treated for TB had a successful TB treatment outcome. The survival on ART at four years of follow-up was 88% among the IPT-initiated PLHIV that was significantly higher than the 75% survival in the group not- initiated on IPT.ConclusionThe study revealed low IPT initiation among eligible PLHIV who, if started on IPT, completed the six month regimen. TB was reported only among the PLHIV not-initiated on IPT and the four year ART survival was higher in the IPT-initiated group than in the non-initiated group. These findings reinforce the need to strengthen IPT uptake among PLHIV in Bulawayo.
