Retrospective analysis of lipid-lowering and antiplatelet therapy regimen by clinical decision support service based on real-world data from electronic medical records "intellect 3 study"

Aim To evaluate prescription of lipid-lowering and antithrombotic therapy in clinical practice and to compare differences in recommendations using the clinical decision support service (CDSS).Material and methods Electronic medical records (EMR) of 300 patients from the Chazov National Medical Research Center of Cardiology, as well as from medical organizations controlled by the Department of Health of the Lipetsk Region and the Ministry of Health of the Voronezh Region, were analyzed for the period of August - December 2022, during the pilot implementation of CDSS. Retrospective information about the prescription of lipid-lowering and antithrombotic therapy from the EMR was compared with the CDSS guidelines under the expert supervision based on digitized clinical and laboratory profiles of patients. The study primary endpoint was a change in the initially prescribed lipid-lowering and / or antithrombotic therapy as per CDSS guidelines.Results Overall 292 patients were included in the final analysis; 46 (15.7 %) were from the primary prevention group and 246 (84.3 %) from the secondary prevention group. In group 1, the lipid-lowering therapy recommended by the CDSS differed by 50 % (p<0.001) from the baseline therapy recorded in the EMR. In the secondary prevention group, 78.9 % (p<0.001) differences were found in the lipid -lowering therapy recommended in the CDSS guidelines compared to the prescriptions in the EMR. In 76.8 % (p<0.001) of patients, antithrombotic therapy was significantly different from the baseline therapy in the EMR.Conclusion The use of CDSS may improve the practice of choosing lipid-lowering and antithrombotic therapy for prevention of cardiovascular complications.
