Increasing Treatment Rates for People with Latent Tuberculosis


Impact Statement: 
The Tarrant County Public Health (TCPH) Tuberculosis (TB) Division in Texas improved completion rates for latent TB infection (LTBI) treatment focusing on three targeted populations: homeless shelter residents, refugees, and people exposed to TB cases. Quality improvement of the process and a new shorter-duration treatment regimen of rifapentine and isoniazid (3HP), raised the completion rate from a baseline of 53% up to 87% in 2015. LTBI treatment is crucial to preventing individuals from developing active TB.

This QI initiative was developed to improve the completion rates for LTBI treatment. The treatment rates have historically been below the national goal and average. LTBI treatment is prescribed to prevent someone from developing active TB, and an increase in LTBI treatment completion rates will lead to a decrease in the number of active cases. This project allows for the delivery of a newer treatment regimen, 3HP, which shortens the duration of therapy.
