Accuracy of administrative and trauma registry databases

Area of Science:

• Trauma Care
• Health Informatics
• Data Management

Background:

• Accurate data are crucial for evaluating trauma patient outcomes and care quality.
• Administrative and trauma registry databases are commonly used for this purpose.
• This study compares the completeness and accuracy of data between these two database types.

Purpose of the Study:

• To compare the accuracy and completeness of trauma patient data between administrative databases and trauma registries.
• To identify specific areas of underreporting within administrative data.
• To determine which database is more suitable for assessing trauma care quality.

Main Methods:

• Data from 2,702 trauma patients injured in 1998 were extracted from both trauma registry and administrative databases.
• Patients were matched based on admission date, medical record number, age, and name.
• Chi-square analysis was used to compare data accuracy and completeness between the two sources.

Main Results:

• Administrative databases significantly underreported mechanisms of injury, diagnoses, interventions, procedures, and complications compared to trauma registries.
• Key diagnostic interventions like CT scans were captured at low rates (40%, 12%, 9%) in administrative data.
• Mortality data was also underreported, with 14 deaths omitted from the administrative database.

Conclusions:

• Administrative data contain substantial omissions regarding injuries, interventions, and complications in trauma care.
• Trauma registries provide a more complete record of diagnoses, procedures, and outcomes.
• Trauma registries are likely more effective than administrative databases for evaluating trauma care quality.
