FONTE GALINDO, Luis et al. Intervention to improve knowledge, perceptions and practices in the diagnosis, treatment and control of giardiasis. Rev Cubana Med Trop [online]. 2013, vol.65, n.3, pp.297-308. ISSN 0375-0760.

Objective: evaluate the results of an intervention aimed at improving physicians' knowledge, perceptions and practices in the diagnosis, treatment and control of giardiasis. Methods: a 27-question survey was designed, validated and given to family doctors from the municipality of Playa, Havana, aimed at inquiring about their knowledge, perceptions and practices in the diagnosis, treatment and control of giardiasis. To make up for deficiencies found in the application of this tool, a number of academic actions were implemented. For example, a book on giardiasis was prepared, published and distributed free-of-charge among all doctors, and lectures on the topic were delivered. Six months after implementation of the intervention, the questionnaire was applied again with the purpose of evaluating the results obtained. Results: the first application of the questionnaire revealed that knowledge was insufficient, perceptions inadequate and practices incorrect. For instance, the mean number of correct answers to the 19 questions on cognitive aspects was 7.69. The second application of the questionnaire showed a significant improvement in practically all the cognitive, perceptual and behavioral aspects evaluated. This time the mean number of correct answers to questions on cognitive aspects was significantly higher (14.61; p< 0.0001). Conclusion: the results obtained from the intervention implemented in the municipality of Playa point to the advisability of its expansion to the rest of the country. They also suggest, once again, the need to regularly monitor and update the contents of training programs for doctors and specialists in relation to the diagnosis, treatment and control of parasitic diseases.
