Injury surveillance is of critical importance in health care. Quality and timely surveillance data are required to evaluate the success and cost- effectiveness of strategies for injury prevention and management. The study was conducted in a state hospital in Sri Lanka with the aim of assessing the in-patient data components of the injury surveillance system. Focus Group Discussions, Key informant interviews, and review of secondary data from Bed Head Tickets and filled Injury Surveillance Forms were carried out. Content analysis was used to analyze qualitative data. Coverage and timeliness of injury surveillance were not satisfactory and there were gaps in the process of surveillance including a lack of room for utilizing gathered data at the institutional level.
