ABSTRACT
A good level of knowledge about hypertension can improve patients' compliance to treatment so achieve better therapeutic results. The aim of our study was to evaluate the degree of knowledge about their disease in hypertensives followed in a hospital out-patient unit; and whether an informative booklet could increase this awareness. The patients were presented a questionnaire on the following items: 1. their interest in health news as presented by the mass-media and their judgement on physicians' willingness to provide information about hypertension; 2. the health hazards of being hypertensive; 3. the importance of a family history of hypertension; 4. life style and blood pressure; 5. the reasons for treating hypertension and the length of treatment. Upon completion of the questionnaire, the patients were handed out a booklet in which these same topics were analyzed. At the next follow-up visit, they were invited to answer a set of questions quite similar to the first ones, but presented in a different verbal form. 200 patients completed the first questionnaire; 159, both of them. Basically, they show a high degree of correct knowledge about their disease, giving between 77% and 94% of correct answers to the different questions. After the booklet, for most of the questions the percentage of correct answers remains the same; when it does change, this is usually for the worse. Simply handing out a booklet doesn't help patients to better understand their disease. On the contrary it may have an opposite effect, inducing some degree of confusion.
