Estudio piloto del beneficio de la utilización de un video como herramienta educativa en pacientes con diabetes tipo 2

Objective: To show an educational video to patients with type 2 diabetes and evaluate changes in diabetes knowledge, glycemic control and quality of life. Methods: Twenty seven patients with type 2 diabetes were randomly selected. A medical history and laboratory studies were obtained and standardized questionnaires about diabetes knowledge, treatment adherence and quality of life were applied. Patients were invited to see the video and afterwards, the diabetes knowledge questionnaire was repeated. A similar evaluation and HbA 1c test were obtained 2 to 6 months later. Results: Subjects were 55 ± 9 years old, had diabetes for 13 ± 8 years and the HbA 1c was 8.5 ± 2.0%. The diabetes knowledge test score in the first, second (immediately after the video) and third examination (2-6 months later) were 69 ± 17, 80 ± 17 and 77 ± 15 respectively (p < 0.0001 compared with the first exam). A low baseline knowledge test score was the most significant variable to predict a
