Latent Tuberculosis Screening Cascade for Non-US-Born Persons in a Large Health System.

Review of electronic health records revealed substantial drop-off at each stage of the latent tuberculosis infection (LTBI) care cascade among non-US-born persons in an academic primary care system. Of 5148 persons eligible for LTBI screening, 1012 (20%) had an LTBI test, and 140 (48%) of 296 LTBI-positive persons received LTBI treatment.
