Satisfaction with Information Regarding Pharmaceutic Therapy in Angiographied Coronary Patients with Type 2 Diabetes

Satisfaction with information regarding pharmaceutic therapy is important because it may strongly affect the appropriate use of drug therapy including medication adherence. No data on this parameter are available in the clinically important population of patients with type 2 diabetes (T2DM) undergoing coronary angiography. We therefore consecutively enrolled a cohort of 272 patients who underwent coronary angiography for the evaluation of suspected or established stable coronary artery disease (CAD) from March through December 2022. From our patients, 94 (34.4% of the total study population) had T2DM according to ADA criteria. 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 or potential problems, respectively. Further, health literacy, which includes the ability to understand and follow instructions for treatment was determined using the EU-HLS-Q16 questionnaire. SIMS-D questionnaires were returned by 196 (71.8%) and EU-HLS-Q16 by 229 (83.9%) patients. Median total SIMS-D scores did not differ significantly between T2DM patients and nondiabetic subjects (11, interquartile range (IQR) 9 vs. 9, IQR 8; p=0.383); independent of T2DM status patients scored significantly lower on items targeting satisfaction with information about potential problems of medication than the in sub-scales for action and usage (p<0.001). In analysis of covariance, health literacy independently of age and T2DM predicted SIMS-D (F=18.55; 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 but is significantly impacted by health literacy.
