Purpose
The purpose of this study was to examine the barriers and facilitators experienced by non-U.S.– born persons during the diagnosis and treatment of latent tuberculosis infection (LTBI) in primary care settings, including the impact of culturally and linguistically congruent care navigation.
Design
25 interviews with non-U.S.–born patients, along with focus groups and surveys with 31 primary care team members and leadership, were conducted.
Setting
The study was conducted within a network of Federally Qualified Health Center (FQHC) clinics.
Participants
Participants were adult non-U.S.–born patients with LTBI and FQHC care team members. A purposefully selected subsample of randomized participants was interviewed.
Intervention
Care navigators followed participants randomized to receive care navigation after a positive test for tuberculosis (TB) infection and offered health navigation and education about the importance of TB screening and treatment.
Method
Data collection was followed by thematic analysis guided by a critical ideological paradigm.
Results
Culturally and linguistically congruent navigation emerged as central to potentially reducing barriers, fostering trust, and improving treatment continuity. Participants without navigation support reported confusion and disengagement from care, while those with culturally aligned navigators described clarity and comfort, with influence overall by intrinsic motivation, relational support, and culturally shaped beliefs about care.
Conclusion
Care navigation that includes culturally and linguistically congruent navigators whenever possible may help increase LTBI treatment completion among non-U.S.–born populations. Limitations of the study include the potential influence of cultural norms, power dynamics, and selection bias.
