Validation of SyS Data to Inform Surveillance of Health Disparities in Nebraska
The objective of this pilot study was to evaluate emergency department (ED) syndromic surveillance (SyS) data quality by cross-validating reported diagnostic codes associated to racial/ethnic injury health disparities in Nebraska. The percent of completeness of core data elements in SyS data and hospital discharge data (HDD) was also determined. Significant correlations were observed between Hospital A 2013 ED HDD and NDHHS ED SyS data for assault-related injury, and suicide and self-inflicted injury. Results suggest that the characterization of the burden of injury health inequalities could potentially be improved by using NDHHS SyS data to complement the surveillance of health disparities.
