Validation of epithelial ovarian cancer and fallopian tube cancer and ovarian borderline tumor data in the Danish Gynecological Cancer Database.

OBJECTIVE

To validate the data on epithelial ovarian cancer, fallopian tube cancer and borderline ovarian tumors registered in the nationwide Danish Gynecological Cancer Database (DGCD) in 2005 and 2006. The DGCD is a multidisciplinary database that contains data for research and quality improvement.

DESIGN

Comparative registry-based study supplemented with data from medical records.

SETTING

Six hospitals in Denmark.

PARTICIPANTS

Women registered with epithelial ovarian cancer, fallopian tube cancer and borderline ovarian tumor.

MAIN OUTCOME MEASURE: Data completeness and strength of agreement.

RESULTS

The estimated completeness of reporting to the DGCD was 94.2% and the strength of agreement between the variables in the DGCD and the medical file varied from moderate to very good. The important quality indicator 'complication' had the lowest strength of agreement.

CONCLUSION

The validity of ovarian cancer data in the DGCD is sufficient for quality monitoring in gynecological oncology.
