With a history of two successful accomplishments for this famous pharmaceutical company, which were delivered in cooperation with Sigma Solutions, Sigma Ukraine received a request 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 customer's researches. The goal of the project was to systemize and enhance the process of COPD patients' information gathering and recruiting for RITA studies (mostly PoC and PoP). This brings significant business benefits since the customer is able to speed up clinical studies and be more efficient in the market. The system is 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 demands on 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 within 9 months, with short term visits of Sigma Ukraine specialists, maintaining a high level of internal and external security to meet the strict requirements of the customer.
EPR is a secured web application operating via HTTPS protocol and accessible using on-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. EPR is clinic context based, so every clinic (entry point) is securely isolated from other clinics data structure and data storage point of view.
The system is built so that all user operations are being 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 all worldwide clinics. The system also their replaces analysis tools, helping the customer and clinic personnel to perform fast look up of the data and identify patients suitable for clinical studies.
Today the system is being used by several clinics in Sweden, Denmark, Finland, and the Netherlands. The Sigma Ukraine 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 Patient Recruitment System.
