Do Instructional Videos on Sputum Submission Result in Increased Tuberculosis Case Detection? A Randomized Controlled Trial.

ABSTRACT:

Objective

We examined the effect of an instructional video about the production of diagnostic sputum on case detection of tuberculosis (TB), and evaluated the acceptance of the video.

Trial design

Randomized controlled trial.

Methods

We prepared a culturally adapted instructional video for sputum submission.
