When a patient or provider tests positive, someone, typically a charge nurse, has to do a manual chart review and “ask around” to figure out who was likely exposed. This approach cannot scale, cannot give us insights into patterns of exposure and spread, and takes staff away from mission-critical patient care.
Our Infection Exposure Tracker automates the detective work necessary to identify:
1) Who provided care to COVID positive patients
2) Who worked side-by-side with COVID positive provider
3) Who was in the vicinity of infected patients and clinicians
This is all done without extra input or work from frontline staff. Health system administrators and public health leaders can access a list of staff, ranked from highest to lowest exposure, which can be filtered by service line. The tracker also keeps a registry of patients and healthcare workers who have tested positive for the virus, who are then presumed immune after they have recovered.
COVID-19 use cases:
We have extensive experience building scalable, robust, and secure systems that interface with electronic medical records. The foundation of the Infection Exposure Tracker is a custom health information exchange, with data visualization and analytics capabilities layered on top.
We built a node that receives HL7 2.x messages on diagnoses, orders, procedures, notes, vitals, ADTs, and medication administrations. From these messages we uncover:
1) Who has been diagnosed with the disease
2) Who is on their care team
3) What actions each provider has taken
Actions that involve involves face-to-face interaction with a patient are counted as "touchpoints". Performing a physical exam, doing a procedure, and administering medications are some of the actions counted as touchpoints. Using a 14-day lookback period, we calculate a the total number of touchpoints for each provider.
Heath system IT departments should allocate three man-days for implementation. Implementation requires the set up of a server that sends us copies of HL7 messages of interest. Installation can be remote. No need to worry about potential interference with production servers; integrating with the support environment is sufficient. All PHI is stored within the hospital’s secure environment, whether on-premise or in the cloud.
