Healthcare personnel interactive pathogen exposure response system

Area of Science:

• Healthcare informatics
• Infectious disease epidemiology
• Health data analytics

Background:

• Traditional exposure investigations for healthcare-associated infections are resource-intensive.
• These methods are prone to recall bias, potentially compromising accuracy.
• Efficient identification of healthcare personnel (HCP) interactions is crucial for infection control.

Purpose of the Study:

• To develop and evaluate an algorithm for identifying HCP interactions using electronic health records (EHR).
• To compare the accuracy of the EHR-based algorithm against conventional exposure investigation methods.
• To assess the feasibility of using EHR data for generating manageable contact lists.

Main Methods:

• Development of a novel algorithm to extract HCP interaction data from EHR systems.
• Validation of the algorithm's performance by comparing its findings with established exposure investigation protocols.
• Implementation of a ranking system within the algorithm to prioritize and manage identified contacts.

Main Results:

• The EHR-based algorithm accurately identified all known transmission events.
• The algorithm successfully generated a manageable list of contacts, reducing the burden of traditional investigations.
• The developed system demonstrated superior efficiency and accuracy compared to conventional methods.

Conclusions:

• An EHR-based algorithm offers a more accurate and efficient approach to identifying HCP interactions for exposure investigations.
• This technology can significantly mitigate the labor intensity and recall bias associated with traditional methods.
• The algorithm provides a scalable solution for contact tracing in healthcare settings.
