A mobile phone Java application accurately tracked subjects during a National Pharmaceutical Stockpile (NPS) distribution drill, demonstrating effective informatics for public health preparedness. This technology offers a reliable alternative to traditional paper recording for managing medication distribution during emergencies.

Area of Science:

  • Public Health Informatics
  • Emergency Preparedness
  • Health Information Technology

Background:

  • The National Pharmaceutical Stockpile (NPS) is critical for public health response to bioterrorism events, such as anthrax exposure.
  • Effective management of medication distribution during a public health emergency requires robust tracking systems.
  • Washington State was an early adopter in staging NPS drills to test response capacity.

Purpose of the Study:

  • To evaluate the use of informatics approaches for monitoring subject flow and time elapsed during an NPS distribution drill.
  • To compare the accuracy of time measurements obtained via a mobile phone Java application against traditional paper recording methods.
  • To assess the feasibility and lessons learned from developing and deploying a mobile health informatics tool in a real-world drill scenario.

Main Methods:

  • Development and deployment of a mobile phone Java application for real-time subject tracking during an NPS drill.
  • Comparison of time measurements recorded by the Java application with data from traditional paper-based recording at multiple drill stations.
  • Statistical analysis, including Pearson correlation, to assess the accuracy and agreement between the two measurement methods.

Main Results:

  • The mobile phone Java application demonstrated high accuracy in tracking subjects and elapsed time, achieving a Pearson correlation of 1.0 at two out of three stations.
  • Minor discrepancies at the final station were attributed to delays in manual recording of exit times.
  • The study successfully validated the informatics approach for monitoring subject numbers and time during a large-scale public health exercise.

Conclusions:

  • Mobile informatics applications offer a precise and efficient method for tracking participants in public health distribution drills.
  • The developed Java application provides a reliable alternative to paper-based systems, enhancing data accuracy and reducing potential recording delays.
  • Lessons learned from this drill inform the future development and implementation of informatics tools for improved emergency preparedness and response.
