In the United States, there is no comprehensive national surveillance system for child agricultural injuries, fatalities, or hospitalizations and in most cases there are no mandatory reporting requirements for these injuries and fatalities. What we know about child agricultural injuries and fatalities comes from periodic injury surveys, periodic analyses of young worker fatalities in agriculture, and occasional reviews of death certificate data. From these sources, we get snapshots but not the full and complete picture of the etiology and consequences of child agricultural injuries, thus there are gaps in our knowledge about both injury causation and the effectiveness of our prevention efforts. The goal of this project, “Filling the Gaps in Child Agricultural Injury Data” is to explore the most promising, existing public health surveillance systems to determine their utility for assessing the health and safety of children in agricultural settings. The focus of the project is on determining how these existing surveillance systems can help to “fill in the gaps” by identifying injury events missed by other methods and/or providing more details about risks, activities, and circumstances surrounding child agricultural injury events. This information, in turn, can help to guide our prevention efforts.
