Extending Existing BI System for Monitoring and Analyzing Infectious Patients in a Hospital Environment

The thesis focuses on extending the existing BI system in a hospital environment, with an emphasis on supporting clinical decision-making in infectious diseases. The main objective of the thesis is to extend the existing BI system in the healthcare institution by creating a clinically oriented dashboard in Tableau, whose primary purpose is to improve the effectiveness of physicians’ decision-making in the area of infectious diseases. Methodologically, the thesis is based on the Design–Science Research Methodology, ranging from needs analysis and data flow design through the visualization layer to deployment within the hospital’s internal network. The result is a dashboard with filters, in which the user selects pairs of antibiotics and obtains a methodologically consistent overview of population coverage and the risk of double resistance. The interpretation of the metrics is illustrated on a practical scenario. The work also includes an evaluation in two iterations with an infectious disease specialist in a routine operational setting and the creation of an action plan with a backlog. The contribution of the thesis lies in shifting the use of BI beyond a purely managerial context towards physicians, increasing the speed and confidence when selecting an antibiotic combination, and providing a documented procedure for integration and deployment.
