Abstract

Treating latent tuberculosis infection (LTBI) in those at risk is an important yet challenging cornerstone of TB elimination. We evaluated a culturally-tailored, multi-lingual, 4.5-min, health promotional video on LTBI. Mixed methods study assessed use of the video with web-analytics, acceptability of content through interviews and survey questions, and compared knowledge scores in viewers and non-viewers using a survey. The video was viewed 6999 times in six languages over 1 year. Of 1598 survey respondents, 193 viewers had a mean knowledge score of 59%, compared to 38% in non-viewers. Eighty-four percent of viewers rated the video as helpful. When controlling for other factors, viewing the video was associated with a 1.04 (95% CI 0.85–1.26) or a 21% increase in a knowledge score. Qualitative data suggested the video was acceptable and may facilitate behavior change. This online, educational video shows promise as a tool to supplement clinical care.
