Factors associated with isoniazid preventive treatment interruption and completion among PLHIV in Gombe Hospital, Uganda, 2017–2019

Tuberculosis (TB) is the leading cause of death in persons living with HIV (PLHIV). PLHIV carry a disproportionate burden of TB infection with risks 20–37 times greater than HIV-negative populations. While isoniazid preventive treatment (IPT) is regarded as a crucial component of HIV care to prevent active TB, the uptake among PLHIV remains very poor. Studies on the factors associated withIPT interruption and completion among PLHIV in Uganda are scarce. Thus, in Gombe Hospital in Uganda, this study assessed the factors associated withIPT interruption and completion among PLHIV. This was a hospital-based cross-sectional study that used both quantitative and qualitative methods of data collection from January 3rd, 2020 to February 28th, 2020. We reviewed the medical records of 686 PLHIV who received IPT at Gombe Hospital from January 1st, 2017 to December 31st, 2019. Binary logistic and modified Poisson regression were used to analyze factors associated with IPT completion and interruption. We conducted 7 key informant interviews and 14 in-depth interviews.
