Abstract

icddr,b in collaboration with JH-IIRU implemented an electronic demographic and injury surveillance system (DISS) to measure 13 injuries as part of the Saving of Lives from Drowning (SoLiD) project in rural Bangladesh. The aim of this paper is to discuss the methodology, challenges and solutions in implementing the DISS. The electronic DISS was implemented in 4 sub-districts from 2014 to 2015 and covered 0.6 million population. A paperless data management software and system was developed for data collection, real time transmission to a central database server and monitoring and supervision. We used tablets with Android operating system (Samsung Galaxy Tab 7.0) and internet enabled SIM card for data collection and transmission to a central database server. The application in the Tablet was developed using JAVA and the data capture interface was in local language. Data were stored locally in the tablet during interview using SQLite. Microsoft SQL Server 2008 R2 was used for the Central data storage. Data were uploaded to the central server through the internet daily at the end of data collection. A monitoring website was developed using ASP.NET code behind C Sharp (C#) to review data collection progress in real-time using any web browser. Validation rules were set to prevent inconsistencies and other errors during data entry. Password-protected login identifications ensured the integrity and safety of data. The main benefits were reduced workload, increased efficiency, timeliness and completeness of collected data. Challenges included issues with data collection processes and operation of the system, internet availability which were resolved using appropriate technical support and training. The use of electronic DISS proved to be beneficial in terms of increasing efficiency, timeliness and completeness. We recommend surveillance practitioners and policymakers to explore the use of electronic systems to improve care provided to individuals.
