The effectiveness of a brochure describing an acceptable method of sputum collection for tuberculosis testing

We evaluated the effectiveness of an educational brochure explaining proper sputum collection techniques for tuberculosis (TB) diagnosis. Patients with suspected pulmonary TB (PTB) were randomly assigned to either the brochure-using group or the non-using group. No significant difference in positive TB culture rates was observed between the brochure-using and non-using groups (33.1% vs. 35.6%, P = 0.690). The proportions of acceptable specimen samples for bacterial pneumonia were also similar between the two groups (37.1% vs. 35.6%). An educational brochure provided by the attending physician explaining an acceptable specimen collection method for TB testing did not result in a higher detection rate of PTB.
