566-P: Satisfaction with Information Regarding Pharmaceutic Therapy in Men and Women with Type 2 Diabetes Undergoing Coronary Angiography

Satisfaction with information regarding pharmaceutic therapy is important because it may strongly affect the appropriate use of drug therapy including medication adherence. Data on this parameter in the clinically important population of patients with type 2 diabetes (T2DM) undergoing coronary angiography is scarce and is therefore addressed in the present study. We consecutively enrolled a cohort of 515 patients (383 men and 132 women) who underwent coronary angiography for the evaluation of suspected or established stable coronary artery disease. Satisfaction with information regarding pharmaceutic therapy was measured using the validated Satisfaction with Information about Medicines Scale (SIMS-D) which consists of two sub-scales covering action and usage (questions 1-9) or potential problems (questions 10-17), respectively. Further, health literacy, which includes the ability to understand and follow instructions for treatment was determined using the EU-HLS-Q16 questionnaire. For SIMS-D a response rate of 68.4% (n=353, 280 men and 73 women) was achieved. From our patients, 124 (36.4% of males and 30.1% of females) had T2DM according to ADA criteria. SIMS-D scores did not differ significantly between T2DM patients and those who did not have diabetes among men 11.5 [IQR=6-16] vs. 9 [IQR=6-15] p=0.121, nor among women 10 [IQR=5.5-12.25] vs. 10 [IQR=5-17] p=0.537. Independent of gender and diabetes status patients scored significantly lower on items targeting satisfaction with information about potential problems of medication than the in sub-scale for action and usage (p<0.001). In analysis of covariance, health literacy independently of T2DM, gender and age predicted SIMS-D (F=41.3; p<0.001). From our findings we conclude that satisfaction with information about medicines in angiographied coronary patients does not depend on the presence of T2DM or gender but is significantly impacted by health literacy.
