The utilization of multiple medications and the increasing complexity of medication regimens associated with chronic diseases such as type 2 diabetes (T2DM) necessitate the implementation of a medication documentation (MD). A complete medication plan serves to enhance medication safety and promotes adherence. The availability of MD in the clinically important population of T2DM patients undergoing coronary angiography for the evaluation of established or suspected stable coronary artery disease (CAD) remains unknown and is addressed in the present study. We analyzed MD, current medication status, and the Medication Regimen Complexity Index (MRCI) in 515 consecutive patients who underwent coronary angiography for the evaluation of established or suspected stable coronary artery disease (CAD). Our cohort included 177 patients (34%) with T2DM and 338 patients (66%) without diabetes. Patients with T2DM compared to those without diabetes had a significantly higher number of medications (7 [5-9] vs. 5 [3-6]; p<0.001) and a significantly higher complexity in medication regimens (17 [11-24] vs. 12 [7-16]; p<0.001). Specifically, out of 104 (59%) T2DM patients, MD was available, while 73 (41%) lacked MD. Further classification showed the following categories of MD in patients with diabetes: unstructured documentation in 28 (27%), physician’s letter in 17 (16%), medication plan in 58 (56%) and other categories in 1 (1%). We conclude that patients with T2DM who undergo coronary angiography for the evaluation of established or suspected stable CAD are affected by a high medication complexity and polypharmacy, which highlights the importance of an accurate MD in these patients. However, proper MD is not available in almost half of these patients. Disclosure P. Elsner: None. M. Ratz: None. J. Vogel: None. C.H. Saely: None. T. Plattner: None. A. Mader: None. B. Larcher: None.
