Programmatic Evaluation of an Algorithm for Intensified Tuberculosis Case Finding and Isoniazid Preventive Therapy for People Living With HIV in Thailand and Vietnam.

Background: Tuberculosis (TB) screening affords clinicians the opportunity to diagnose or exclude TB disease and initiate isoniazid preventive therapy (IPT) for people living with HIV (PLHIV).

Methods: We implemented an algorithm to diagnose or rule out TB among PLHIV in 11 HIV clinics in Thailand and Vietnam. We assessed algorithm yield and uptake of IPT and factors associated with TB disease among PLHIV.
