The District of Columbia (DC) and 41 states routinely collect some level of E-codes; 26 (63%) states and DC mandated E-coding in their statewide HDDS database (Figure 2), and 27 (54%) states and DC had an HEDDS database.
These reports have been used for comparison of injury patterns among states and have resulted in improved communication among states regarding injury-prevention efforts and efforts to improve statewide HDDS and HEDDS E-coding (31).
QA practices vary by state; the majority of states do not evaluate E-coded HDDS and HEDDS data routinely for completeness, specificity, and accuracy (10).
Certain HDDS and HEDDS databases are operated by nongovernment organizations that view these data as proprietary and do not necessarily wish to provide ready access to statewide administrative data by state health department officials or prevention program directors (10).
Quality E-coded data in statewide HDDS and HEDDS also have been used by federal agencies that collect and use state injury data to monitor trends, set priorities for funding prevention programs, and assess program effectiveness in reducing nonfatal injuries.
The uses of E-coded data in statewide HDDS and HEDDS complements those from trauma registries of severe trauma patients treated in trauma centers by characterizing a broader representation of the injured patient population.
E-coded statewide HDDS and HEDDS data have been used to help identify key causes of injuries requiring medical attention that could be addressed by implementing safety measures and policies, which has resulted in cost savings to these companies.
The workgroup made the following recommendations to improve E-coding in statewide HDDS and HEDDS databases.
assess the inclusion of E-codes in federal morbidity data systems, surveys, and data standards to facilitate routine collection of high-quality E-codes in statewide HDDS and HEDDS databases.
developing methods to track improvement in the completeness, accuracy, and specificity of E-codes in HDDS and HEDDS among states and territories.
