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 Louisiana Early Event Detection System database to SQL server from Oracle and expand the system to accept data from 300 additional emergency care facilities.

• Reduce manual processing
• Improve staff efficiency by streamlining operations
• Increase transparency and early detection of epidemics through reporting and analytics
• Created an informational asset for Epidemiology Data
• Facilitates collaboration between regional health units and hospitals

LATB Description

The Louisiana Tuberculosis (LaTB) Case Management system will allow regional health units to manage and collaborate on Louisiana TB cases from various locations. Currently, TB users are manually transferring each regional MS Access database and merging each of the nine regional databases into one master database. The new web-based system, which is currently in User Acceptance Testing, will reduce patient record duplication and manual database merges. TEI has been working with the LaTB staff to complete the UAT (User Acceptance Testing) phase of development and plans to deploy the system into production in early 2018.

Key Features

• Case Management Solution
• Centralized Database of Patient Records
• Real Time Data Updates
• User-Friendly Web Interface
• Patient Tracking
• Lab Data Component
• User Security Management
• Duplication Identification
• Accessible from Any Regional Office
• Robust Reporting Abilities
• Error Reduction
• Seamless Collaboration For Health Units


LEEDS Description

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.

Key Features

• Real Time Data Updates
• Retro Mapping
• User-Friendly Web Interface
• Configurable Code Tables
• Robust Reporting Capabilities



The Epistories system gathers epidemiological data and narratives from hospitals and public health clinics throughout Louisiana. TEI improved the user interface and converted Epistories from a Java to Microsoft ASP.NET in the first six months of our original contract with DHH. This conversion eliminated the high support costs of the system and allowed TEI to create the Louisiana Animal Disease Surveillance System and Bioterrorism Incident Tracking System. The Louisiana Animal Disease Surveillance System (LADSS) is used by veterinarians to identify and monitor Arboviruses in animals. The Bio-Terrorism Incident Tracking System (BITS) was developed to meet the potential threats of bioterrorism.

Key Features

• Case Management
• Lab Component
• E-mail Notification Component
• User Profile Maintenance
• Multiple Levels of User Security
• Data Import Function
• Search Abilities
• Audit Trail
• Configurable Code Tables
• Robust Reporting Capabilities
