Improving health system efficiency in tuberculosis prevention and control through targeted LTBI screening in the foreign-born
RESEARCH GOAL AND OBJECTIVES
We hypothesize that certain subgroups within foreign-born populations are at higher risk for TB and can be identified based on demographic and medical risk factors.
1. Overall goal
This proposal focuses on the development and implementation of targeted, evidence-based, and cost-effective latent tuberculosis infection (LTBI) screening recommendations for the foreign-born population of BC. The evidence generated by this study will allow us to evaluate current screening guidelines and will guide decisions on the implementation of population based foreign-born LTBI screening programs across Canada.
2. Study objectives
The objectives of this study are threefold:
i. To identify specific subgroups of the foreign-born population that are at high-risk for active TB based on demographic and medical risk factors. This will include the development of a TB risk score that will quantify an individuals risk of active TB depending on demographic and medical risk factors.
ii. To determine which high-risk populations would be most cost-effective to screen and treat for LTBI from a health systems perspective (Phase 2).
iii. To implement the most cost-effective strategies across the province through a network of stakeholders, physicians and community groups by leveraging an established provincial TB strategic implementation group (Phase 3).
