Latent Tuberculosis Infection: Treatment Initiation and Completion Rates in Persons Seeking Immigration and Health...

Area of Science:

• Infectious Diseases
• Public Health
• Epidemiology

Background:

• Latent tuberculosis (TB) infection affects millions in the US, with a significant risk of progression to active TB.
• Effective treatment of latent TB infection is crucial for national TB eradication strategies.
• Assessing factors influencing treatment adherence is vital for public health initiatives.

Purpose of the Study:

• To identify factors associated with latent TB infection treatment initiation and completion.
• To evaluate the impact of follow-up frequency and patient demographics on treatment outcomes.
• To inform strategies for improving latent TB infection management in outpatient settings.

Main Methods:

• Retrospective chart review of patients at an infectious diseases outpatient clinic.
• Data collected from December 2006 to October 2010.
• Analysis of treatment initiation, completion, and refusal rates.

Main Results:

• Overall treatment initiation and completion rates were 76% and 68%, respectively.
• Four or more follow-up visits significantly increased treatment completion rates (P < 0.001).
• Persons seeking immigration showed higher treatment completion rates (P < 0.02); healthcare workers had higher refusal rates (35% vs 13%).

Conclusions:

• Findings on treatment completion in persons seeking immigration and the impact of follow-up visits are novel for US literature.
• A minimum of four follow-up visits may serve as an effective intervention to boost latent TB treatment completion.
• Targeted strategies considering patient background and ensuring consistent follow-up are recommended for TB control.
