Latent Tuberculous Infection Testing Among Hiv-Infected Persons In Clinical Care, United States, 2010-2012

SETTING: Current guidelines recommend latent tuberculous infection (LTBI) testing at the time of human immunodeficiency virus (HIV) diagnosis and annually thereafter for persons at high risk of LTBI.OBJECTIVES: To estimate LTBI testing prevalence and describe the characteristics of HIV-infected persons who would benefit from annual LTBI testing.DESIGN: We estimated the proportions of LTBI testing among a nationally representative sample of HIV infected adults in care between 2010 and 2012, and compared the patient characteristics of those with a positive LTBI test result to those with a negative result using chi(2) tests.RESULTS: Among 2772 patients, 68.8% had been tested for LTBI at least once since HIV diagnosis, and 39.4% had been tested during the previous 12 months. Among patients tested at least once, 6.9% tested positive, 80.7% tested negative, and 12.4% had an indeterminate or undocumented result. Patients with a positive test were significantly more likely to be foreign born, have lower educational attainment, and a household income at or below the federal poverty level.CONCLUSIONS: More than 30% of HIV-infected patients had never been tested for LTBI. Providers should test all patients for LTBI at the time of HIV diagnosis. The patient characteristics associated with a positive LTBI test result may guide provider decisions about annual testing.
