• Variability in Data Quality
• Development of the NTDS
• Implementation of NTDS

Need for a National RegistryNeed for a National Registry
• Provide a national resource for clinical benchmarking, process improvement, and patient safety
• Characterize all patient care • Provide baseline measures for
enhancing disaster preparedness • Develop better injury scoring and
outcome measures • This is not necessarily surveillance

States with RegistriesStates with Registries
• 27/32 require hospitals to report– 11 states…all acute care hospitals– 15 states…only designated centers– 1 state…only participating hospitals
• 5/32 request hospitals report– 2 states…all acute care hospitals– 1 state…only designated centers– 2 states…partial registries

Threats to Data IntegrityThreats to Data Integrity
• Mandatory/elective Submission– Completeness of Case Capture
• Difference in Case Definition
• Difference in Coding Conventions

Call for DataCall for Data
2008 First NTDB call for data based on
NTDS version 1.2 Map current registry fields to the new
standard
2009 Second NTDB call for data based on
NTDS version 1.2 Updated software from vendors that
incorporates all the new data fields and allows for direct data entry.
