About NCHS DOQS
The National Center for Health Statistics Data Online Query System (NCHS DOQS) is based on the Utah Department of Health data query system IBIS-PH. The system provides dynamically generated statistical tables, charts, and graphs using NCHS public use data.
NCHS DOQS gives users the ability to generate and store in-depth statistical analyses customized to their specific requirements. The system is designed for the general user without knowledge of commercial statistical software packages, and for any user who does not require in-depth statistical analysis. Currently, NCHS DOQS houses data from the Emergency Department component of the National Hospital Ambulatory Medical Care Survey (NHAMCS-ED), 2005–2010.
