A Novel Algorithmic approach for Covid-19 contact tracing, improves productivity and Patient flow process efficiency

Effective pandemic response and prompt actions for containing the transmission of COVID-19 requires a robust and efficient system. We describe our innovative design and build of an algorithm that integrates available data from multiple hospitalbased informatics systems that perform different daily functions to augment the contact tracing process of COVID-19 patients through identifying exposed neighboring patients and healthcare staff and assess their risk. Prior to the establishment of the algorithm, contact tracing teams comprising six members each would spend up to 10 hours to complete contact tracing for five new COVID-19 patients. With the augmentation by the algorithm, we observed ≥60% savings in overall man-hours needed for contact tracing when there were five and above daily new cases through a time-motion study and Monte-Carlo simulation. This improvement to the hospital’s contact tracing process supported more expeditious and comprehensive downstream contact tracing activities as well as improved manpower utilization for contact tracing. Additionally, automated patient touch point analysis using digital footprints (time stamps) captured in live IT systems is continually evolving with the use of IOT and wearable devices, and we observe the use of smart algorithms for patient flow analytics translating to operational process efficiency and patient safety. Current limitations of our algorithm include the challenges associated with monitoring visitor movements and identifying inflight proximal human touch points using video analytics. We recommend future real-time patient flow dashboards to incorporate case level views mapping patient journey for smart healthcare needs
