Patient navigator's role in latent tuberculosis infection at a New York City Health Department Chest Clinic

Background: Philippines is one of the top ten countries of birth among individuals with tuberculosis in New York City (NYC). The NYC Health Department (HD) screened Filipino-born New Yorkers for latent TB infection (LTBI), but few of those tested positive completed evaluation and treatment. Objective: To increase the proportion of Filipinos with a positive QuantiFeron-TB Gold Plus (QFT-Plus) complete LTBI evaluation and treatment. Methods: Nine community-based LTBI screening events were conducted during September-December 2021. Patients with positive QFT-Plus results were offered no-cost LTBI evaluation and treatment at HD Chest Clinic. The HD engaged culturally- and linguistically-competent Filipino patient navigators (PN) to facilitate LTBI evaluation and treatment. Results: Of 77 Filipinos screened, 17 (22%) tested positive. Fourteen (82%) were evaluated for LTBI; eight of the 14 (57%) completed LTBI treatment. Conclusions: Pairing patients with culturally- and linguistically- competent Filipino PNs contributed to an increase in the proportion of Filipinos with a positive QFT-Plus who completed LTBI evaluation and treatment. TB prevention programs may wish to consider PNs in LTBI patient care.
