Developing a User-Centric System for Hospital-Onset Bacteremia Risk Assessment and Visualization: An Integrated...

Area of Science:

• Medical Informatics
• Clinical Decision Support Systems
• Infectious Disease Epidemiology

Background:

• Hospital-onset bacteremia (HOB) is a frequent healthcare-associated infection.
• HOB significantly increases patient morbidity and mortality within hospitals.
• Data-driven decision support tools can aid in HOB risk assessment.

Purpose of the Study:

• To define clinician needs for a digital HOB risk assessment application.
• To develop an interdisciplinary approach for requirement gathering.
• To incorporate user feedback from the initial stages of development.

Main Methods:

• Utilized interviews and questionnaires to gather non-functional and functional requirements.
• Focused on requirements for data management, analysis (backend), and visualization (frontend).
• Involved thirteen healthcare professionals from eight German university hospitals.

Main Results:

• Identified key requirements for both backend and frontend components.
• Requirements cover data collection, risk prediction, data input/export, and user interface design.
• Requirements were classified into four distinct groups.

Conclusions:

• Established a foundational set of requirements for a user-centric HOB risk assessment tool.
• The identified requirements support the development of interactive visualizations.
• This work paves the way for an effective digital decision-support system for HOB.
