Dr. Grannis collaborates closely with national and international public health stakeholders to advance technical infrastructure and data-sharing capabilities. He was a member of World Health Organization (WHO) Collaborating Center for the Design, Application, and Research of Medical Information Systems, where he provided consultancy on issues related to health information system identity management and implementing automated patient record matching strategies.
Dr. Grannis’ analysis of an automated regional electronic laboratory reporting system revealed substantial increases in the capture rates for diseases of public health significance when compared to manual, paper-based procedures. He directed an initiative integrating data flows from over 120 hospitals across the state of Indiana for use in public health disease surveillance. For the last five years this system has received real-time data from hospitals amounting to more than two million transactions per year, and has detected public health outbreaks of gastrointestinal illness, carbon monoxide poisoning, and other events of interest to public health. This system also was leveraged to monitor H1N1 influenza disease burden across the state of Indiana.
