Summary
The Danish Fracture Database (DFDB) showed low data completeness (55.4%) in 2016, but high validity for key surgical variables. This highlights areas for improvement in fracture data collection.
Area of Science:
- Orthopedic surgery
- Health informatics
- Database management
Background:
- The Danish Fracture Database (DFDB) is crucial for monitoring fracture care.
- Assessing the completeness and validity of registry data is essential for reliable analysis.
Purpose of the Study:
- To evaluate the completeness of the DFDB overall and by hospital volume.
- To determine the validity of independently assessed variables within the DFDB.
Main Methods:
- A retrospective review of fracture surgery cases from 2016 registered in the DFDB.
- Completeness was assessed using sensitivity; validity was assessed using positive predictive values (PPVs).
- Data were analyzed stratified by hospital volume (small vs. large).
Main Results:
- Overall DFDB completeness was 55.4%.
- Completeness was higher in small-volume hospitals (60%) compared to large-volume hospitals (52.9%).
- The PPV for key variables (operated side, surgery date, surgery type) was high, ranging from 98% to 100%.
Conclusions:
- Data completeness in the DFDB was found to be low in 2016.
- Despite low completeness, the validity of recorded data in the DFDB was high during the same period.
