Audit-Based Quality Validation of the Japan Cardiovascular Surgery Database.

Area of Science:

• Cardiovascular Surgery
• Health Informatics
• Data Quality Assurance

Background:

• The Japan Cardiovascular Surgery Database (JCVSD) is a national registry for cardiovascular surgery patients in Japan.
• On-site institutional audits have been conducted since 2004 to assess and enhance data quality.
• This study evaluated the accuracy of registered JCVSD data against on-site audit findings.

Purpose of the Study:

• To investigate the accuracy of data registered in the Japan Cardiovascular Surgery Database (JCVSD).
• To compare data collected during on-site audits with the registered data in the JCVSD.
• To identify areas for improvement in data quality and input systems within the JCVSD.

Main Methods:

• Conducted on-site audits at 95 facilities participating in the JCVSD.
• Compared registered data with data collected during the site visits.
• Analyzed accuracy rates for case registration and specific data fields.

Main Results:

• Achieved a case registration accuracy of 98.74% across the audited facilities.
• Demonstrated high data input accuracy exceeding 90% for most fields.
• Identified specific fields with high accuracy (e.g., diabetes, aortic stenosis, mortality at ~99%) and pinpointed common errors and system issues.

Conclusions:

• Confirmed a high level of registration accuracy within the JCVSD.
• Validated the effectiveness of focused, well-resourced site visits for national data quality control.
• Emphasized the necessity of ongoing development to maintain high standards in Japanese cardiovascular surgery data.
