Data quality validation of the Spanish Incisional Hernia Surgery Registry (EVEREG): pilot study.

PURPOSE

The Spanish Incisional Hernia Surgery Registry (EVEREG) was promoted by the Abdominal Wall Section of the Spanish Association of Surgeons, starting data collection in July 2012 and currently has more than 14,000 cases. The objective of this study was to validate the data collected through a pilot audit process.

METHODS

A sample of hospitals participating in the EVEREG registry since the beginning was selected. Patients registered in these centers in the 2012-2020 period were included. A stratified random sampling was carried out, with the inclusion of 10% of registered cases per center with a minimum of 20 cases per center. At each participating center, two researchers not belonging to the center undergoing the audit checked (on site or telematically) the concordance between the data in the registry and the data contained in the case history of each patient.

RESULTS

330 patients have been analyzed, out of a total of 2673 registered, in 9 participating centers. The average accuracy has been 95.7%. Incorrect data 1.5% and missing data 2.3% CONCLUSION: The group of pilot hospitals from this EVERG incisional hernia surgery registry shows a very high precision of 95.7%. The confirmation of these findings in all the centers participating in the registry will make it possible to guarantee the quality of the studies made and their comparability with other similar national registries.
