Evaluation of Latent Tuberculosis Infection Screening in the Field Setting
Issue: In 2013, the department began the implementation of IGRA in the clinic and field setting as evidence based practice for public health nursing. This presentation will report the evaluation of this implementation of IGRA including: (a) usage of IGRA in the field, (b) comparison of latent TB infection rates in 2013 and 2014, and (c) cost analysis of screening with TST and IGRA.
Lessons Learned and Implications: The evaluation showed that adoption of evidence based practices can vary in different settings and barriers need to be identified and addressed in order to ensure implementation that benefits patient outcomes. TB infection rates decreased after IGRA implementation, likely due to IGRA’s increased sensitivity and specificity. The change to IGRA testing was cost effective due to a decrease in LTBI treatment as fewer TB false positive tests occurred. Implications for all local public health departments include the feasibility of IGRA testing in the public health field setting and the improvement in identification of true TB infections.
