Evaluation of a pamphlet on visceral leishmaniasis as a tool for providing disease information to healthcare professionals and laypersons.

Abstract

Although educational materials are frequently produced and used as part of control programs in Brazil, little is known about the efficacy of this type of information. This study evaluated the potential for disseminating information on visceral leishmaniasis using a pamphlet. The sample consisted of 551 healthcare workers and 379 laypeople from a metropolitan area located in southeast Brazil. Both before and after reading the pamphlet, subjects completed a multiple-choice questionnaire. Overall baseline knowledge of the disease was estimated by the proportion of correct answers before reading the pamphlet. Although specific knowledge among zoonosis control workers was higher (90.0% on average), overall baseline knowledge of the disease varied from 45.0% to 77.0%. After reading the pamphlet, the levels increased to 71.0% and 96.0%, respectively. Before reading, the lowest proportion of correct answers in all groups related to the disease symptoms. Analysis of incorrect answers showed that visceral leishmaniasis is mainly confused with leptospirosis. The increased proportion of correct answers after reading the pamphlet is evidence of its potential as an educational tool.
