Screening and Treatment Rates for Latent Tuberculosis Among Newly-Arrived Refugees in an Urban Facility in Connecticut.

There is a high prevalence of latent tuberculosis infection (LTBI) and risk of reactivation among refugees. This study describes LTBI prevalence, treatment initiation, and completion rates in refugee patients seen at one urban Connecticut hospital. This retrospective chart review includes 248 adult refugee patients screened between January 2009 and April 2012. Demographics, tuberculin skin test (TST) results, treatment initiation and completion rates, and treatment-related variables were collected. Ninety-eight percent of adult refugees received TST screening and 44.0% were diagnosed with LTBI. Of these, 95.5% initiated treatment, and of those, 48.2% completed treatment. Early treatment discontinuation was high, with 29.5% of patients diagnosed with LTBI defaulting after the first clinic visit. Despite near-universal screening within this refugee population, LTBI treatment initiation and completion rates remain low. Greater efforts should be made to ensure LTBI treatment initiation and completion among refugees through early case management and shorter treatment duration.
