Summary of Work
Infectious Disease Epidemiology Section requested help to support, maintain, and enhance existing legacy information and data collection systems, as well as to develop new specialized systems for identifying and tracking outbreaks of infectious and communicable diseases.
Meeting with the principal Office of Public Health management staff, TEI analysts gathered and documented system requirements for each proposed system. Under the direction of our Chief Software Architect, our analysts developed intuitive browser designs for four of the most critical systems used by the Epidemiology Section. Using Microsoft’s ASP.Net architecture, our software developers improved overall system functionality by developing new algorithms for use with the existing database. Throughout the contract period, we used our standard information system development methodologies to design, program, and all processes.
Essentially, TEI helped bring syndromic surveillance into the Internet age. In 2011, TEI had completed and implemented four major systems used by state epidemiologists to track infectious and communicable diseases. More recently, TEI developed a web application for Louisiana Tuberculosis (TB) Case Management that allows regional health units to manage and collaborate on Louisiana TB cases from various locations. TEI is currently under contract with DHH to migrate the Louisiana Early Event Detection System database to SQL Server from Oracle and expand the system to accept data from 300 additional emergency care facilities.
The Louisiana Early Event Detection System (LEEDS) automatically processes emergency rooms and urgent care facility data from all over Louisiana into standardized reports that help predict epidemics in the early stages of an outbreak. TEI created the LEEDS system to streamline public health staff’s manual processes. Three main components: data transfer component, the data analysis processing component, and the reporting component encompass the LEEDS system. The data analysis processing component is a data extraction and transformation tool that allows the program administrator the ability to configure analysis algorithm settings, schedule data loads, review processing results and resolve data discrepancies before the data’s integration into the reporting component. The data is transformed based on disease tracking algorithms into a series of standardized reports for the hospitals and program administrators. With a click of a button, public health staff can process massive amounts of data that previously took weeks of manual processing.
Recently, TEI has completed the full migration of the LEEDS database to SQL server from Oracle in addition to several system enhancements such as increased batch processing speed, added user account management, and updated the system to acceptance and intake of HL7 files. We are also nearing completion on the system-wide expansion of accepting data from 300 additional emergency care facilities across the state.
