Having produced two successful solutions for this well-known pharmaceutical company, which were delivered in cooperation with Sigma Solutions, Sigma Software was requested to develop an Enhanced Patient Recruitment System (EPR).
The EPR system is intended for centralized patient database management and analysis in order to define patients suitable and available for clinical studies for the customer's research. The goal of the project was to systemize and enhance the process of COPD patients' information gathering and recruiting for RITA studies (mostly PoC / PoP). This brings significant business benefits since the customer is able to speed up clinical studies and operate more efficiently on the market. The system is a centrally hosted web application serving several clinics in Europe and providing analysis interfaces for the customer's personnel.
Since the application is developed for clinical personnel, the greatest challenge was to create user interfaces fulfilling the highest requirements for usability. In order to ensure that all expectations of end users are met, the project was performed using several steps of daily clinic processes analysis, prototyping (visual prototypes, clickable prototype), and meetings with clinic personnel onsite.
The project was developed offsite in 9 months, with short term visits of Sigma Software specialists, while maintaining a high level of internal and external security to meet the strict requirements of the customer.
The EPR is a secured web application operating via HTTPS protocol and accessible using one-time-password technologies. The system works as a web application accessed through IE browsers and developed as 3-tier architecture with presentation, business logic and data layers. The EPR is a clinic context-based system, so every clinic (entry point) is securely isolated from other clinics` data structures and data storage.
The system is built so that all user operations are tracked and logged and any change in the system is stored in the history so that any previous system state can be restored on demand.
System administrators (system-wide and clinic-wide) are able to configure the data structure for the patient database by adding new attributes with various data types, introducing business rules and relations between particular fields in a patient questionnaire. Thanks to high performance real time data synchronization mechanisms (SQL Server-based), the customer has up-to-date patient data collected from their clinics all over the world. The system also replaces analysis tools, helping the customer and clinic personnel to perform fast data searches and identify patients suitable for clinical studies.
Today the system is used by several clinics in Sweden, Denmark, Finland, and the Netherlands. The Sigma Software team has finished the data import processes needed to put previously collected patient data into the system ready for the customer to start working with old and new patient databases using the new Enhanced Patient Recruitment System.
