Abstract:
Healthcare-associated infections (HAIs) may have grave consequences for patients. In the case of sepsis, the 30-day mortality rate is about 25%. HAIs cost EU member states an estimated 7 billion Euros annually. Clinical decision support tools may be useful for infection monitoring, early warning, and alerts. MONI, a tool for monitoring nosocomial infections, is used at University Hospital Vienna, but needs to be clinically and technically revised and updated. A new, completely configurable pipeline-based system for defining and processing HAI definitions was developed and validated. A network of data access points, clinical rules, and explanatory output is arranged as an inference network, a clinical pipeline as it is called, and processed in a stepwise manner. Arden-Syntax-based medical logic modules were used to implement the respective rules. The system was validated by creating a pipeline for the ECDC PN5 pneumonia rule. It was tested on a set of patient data from intensive care medicine. The results were compared with previously obtained MONI output as a suitable reference, yielding a sensitivity of 93.8% and a specificity of 99.8%. Clinical pipelines show promise as an open and configurable approach to graphically-based, human-readable, machine-executable HAI definitions.
Insights
A new clinical pipeline system improves healthcare-associated infection (HAI) detection. This configurable tool offers a human-readable, machine-executable approach for infection monitoring and alerts.
Area of Science:
- Medical Informatics
- Infectious Disease Epidemiology
- Clinical Decision Support
Background:
- Healthcare-associated infections (HAIs) pose significant risks, including a 25% 30-day mortality rate for sepsis.
- HAIs incur substantial economic costs, estimated at €7 billion annually for EU member states.
- Existing tools like MONI require clinical and technical updates for effective infection monitoring.
Purpose of the Study:
- To develop and validate a novel, configurable pipeline-based system for defining and processing HAI definitions.
- To enhance clinical decision support for infection monitoring, early warning, and alerts.
- To provide a flexible and open approach for HAI definition management.
Main Methods:
- Developed a configurable pipeline-based system using a network of data access points and clinical rules.
- Implemented rules using Arden Syntax-based medical logic modules within a clinical pipeline framework.
- Validated the system by creating a pipeline for the ECDC PN5 pneumonia rule and testing on intensive care patient data.
Main Results:
- The new system achieved high performance in detecting pneumonia, with a sensitivity of 93.8% and a specificity of 99.8%.
- Results were validated against the established MONI system, demonstrating comparable or improved accuracy.
- The clinical pipeline approach proved effective for processing HAI definitions.
Conclusions:
- Clinical pipelines offer a promising, open, and configurable method for HAI definitions.
- This approach facilitates human-readable and machine-executable HAI definitions.
- The validated system demonstrates potential for improving HAI surveillance and patient safety.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
