Introduction and Objective: Satisfaction with medical information plays a critical role in appropriate medication use and is fundamental to pharmacotherapy. This study addresses the lack of data on this important issue in the clinically important population of patients with type 2 diabetes (T2DM) undergoing coronary angiography.Methods: We consecutively enrolled 697 patients who underwent coronary angiography for the evaluation of suspected or established stable coronary artery disease. Satisfaction with information regarding pharmacotherapy was measured using the validated Satisfaction with Information about Medicines Scale (SIMS-D) consisting of two sub-scales covering action and usage or potential problems. Further, health literacy, which includes the ability to understand and follow instructions for treatment, was determined using the EU-HLS-Q16 questionnaire.Results: For SIMS-D, a response rate of 67.9% was achieved. Overall, 31.9% had T2DM according to ADA criteria. Mean age was 67.6±10.9 years (272 patients <65 years, 425 patients ≥65 years). SIMS-D scores did not differ significantly between T2DM patients and those without diabetes among patients <65 years (9 [IQR:6-15] vs. 9 [IQR:5-14], p=0.903) nor among patients ≥65 years (12 [IQR:7-16] vs. 10 [IQR:6-16], p=0.385). Independently of age categories and diabetes status, patients scored significantly lower on items targeting satisfaction with information about potential problems than in the sub-scale for action and usage of medication (p<0.001). In analysis of covariance, health literacy independently of T2DM, gender and age predicted SIMS-D (F=62.648; p<0.001).Conclusion: From our findings we conclude that satisfaction with information regarding pharmacotherapy in angiographied coronary patients does not depend on the presence of T2DM or age, but is significantly associated with health literacy.
