Injuries are a major but neglected global public health problem. In 2001, World Health Organization (WHO) published injury surveillance guidelines emphasizing the importance of injury surveillance at country levels to cope with this grave problem. However there are no customizable generic injury surveillance systems which can be used in developing countries. Therefore we conducted this study to customize open source public health information system, District Health Information System 2 (DHIS2) for injury surveillance and pilot it in a resource constrained country, Sri Lanka.
