Lack of injury data is a major drawback in injury prevention in Sri Lanka. We designed, developed and piloted a web-based Injury Surveillance System (ISS) for Sri Lanka. Previously, Sri Lanka had an ISS comprised a paper-based data collection tool and its corresponding software application; that system had several deficiencies and was nonfunctioning. We Identified and addressed those deficiencies and developed a new web-based ISS. The pilot test showed that the new ISS is a feasible and sustainable mean of injury surveillance in Sri Lanka. Settings with limited informatics resources can learn from our approach to develop the new ISS.
