General description
The National Trauma Data Bank (NTDB) is a de-identified dataset based on the U.S. trauma registry, with over 7.5 million electronic records from more than 900 trauma centers. Data are provided by voluntary hospitals, submitted in a standardized format following the National Trauma Data Standard.
Variable categories
- Demografic
- Pre-hospital
- Injury
- Emergency department
- Hospital procedure
- Pre-existing conditions;
- Diagnosis
- Hospital events;
- Measures of process of care;
- Surgeon-specific reporting.
Limitations
- NTDB is not nationally representative since its data are voluntarily submitted. However, all level I/II trauma centers now provide data to the NTDB, so the data can be considered nationally representative of those facilities.
- The NTDB is an incident-based record, each incident is recorded independently of repeated injuries.
- NTDB does not include data on costs, laboratory values, and long-term outcomes, including readmissions and functional outcomes.
- Researchers should be mindful of distinct patient subpopulations that can alter their results. This selection bias refers to the differences between groups due to differences in inclusion, such as the differences in hospital-level addition of isolated hip fractures and transferred patients.
