Abstract
IntroductionTo assess the effects of a visual Decalogue aid on the degree of knowledge, control perception and improvement in cardiovascular risk factors (CVRF). Material and methodsA Primary care randomised non-pharmacological trial of an educational intervention with a parallel control group, and blind evaluation in type 2 diabetic patients. Both groups received an educational intervention on the management of CVRF. The intervention group also received a visual Decalogue aid that showed the level of control patients have over the modifiable CVRF. A total of 50 patients were included in each group in order to identify an improvement of 50% in the multifactorial knowledge of CVRF. All patients received a reminder telephone call at 2 months, with masked evaluation of knowledge and CVRF control perception. In a 6 months visit the level of knowledge and real control of CVRF were re-evaluated. ResultsThe study included 51 males and 49 females, with mean age of 62.9 years, a mean disease duration of 9.2 years, and low educational level. The level of knowledge, control perception, and real control at baseline was 55%, 80.4%, and 65.9%, respectively. After 2 months the level of knowledge in the Decalogue group increased by 16.5% more than in the conventional education group (73.6% vs. 63.2%; P<.05) and the overestimated control perception improved by 34.5% (P<.001) with no differences between groups, although concordance was better in the Decalogue group. At 6 months there was an overall increase 25.6% (P<.001) in the level of knowledge, with the previous difference between groups levelling off. The final CVRF control improved overall and in the Decalogue group by 6.4% (P<.005) and 9.4% (P<.001), respectively. The SCORE risk significantly decreased overall with no differences between groups. ConclusionsThe educational intervention improves the overall level of knowledge, perception and control of CVRF. The CVRF Decalogue quickly increases the level of knowledge, and decreases the false subjective risk control perception. The benefit, however, becomes equal at 6 months with ongoing education interventions.
