Objectives:
To examine socio-demographic and health-related factors associated with latent tuberculosis infection (LTBI) treatment refusal, non-initiation, and non-completion among a cohort of Vietnamese immigrants.
Design:
This is a retrospective cohort study in which LTBI charts were reviewed at a public health clinic in Orange County, California between January 2010 and August 2011.
Sample:
Altogether, 474 patient charts with documented LTBI treatment were reviewed for patients who met the inclusion criteria.
Measurements:
Univariate and multivariate analyses were used to identify socio-demographic and health-related factors associated with LTBI treatment refusal, non-initiation, and non-completion.
Results:
Of the 474 charts reviewed, 171(36.1%) patients refused LTBI treatment and 21(6.9%) accepted but did not initiate. Of the 282 that started treatment, 62 (22.0%) did not complete the regimen prescribed. The primary barrier documented for treatment refusal and non-completion was concern about medication side effects. Other barriers to treatment non-completion include transportation issues and conflicts with travel plans or work schedules.
Conclusions:
Community and public health nurses working with the Vietnamese immigrant population can play a vital role in improving patients' LTBI treatment acceptance, initiation, and completion. A proactive approach to addressing barriers and potential medication side effects can improve overall treatment success.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
