Data quality assessment in the SWEDEHEART registry: Insights from serial audits on completeness and accuracy
Authors' conclusion
The SWEDEHEART registry is a highly complete and accurate source of patient characteristics and processes of care
Study context
- Population
- Sites reporting to the Swedish quality registry for cardiac disease (SWEDEHEART); data audited against electronic medical records>200,000 data points controlled
- Participants
- 72 / 30 / 75
- Exposure
- SWEDEHEART-ACS vs SWEDEHEART-PCI vs SWEDEHEART-CR
- SWEDEHEART-ACSn = 72
- SWEDEHEART-PCIn = 30
- SWEDEHEART-CRn = 75
- Outcome
- Data completeness and accuracy vs electronic medical records
- Follow-up
- 2017 to 2018 audit

Further findings
Accuracy across all 4 audits (2011 to 2018)
- Accuracy >95.0% for all subregistries at all 4 audits
- P for trend < 0.0001
Most often incomplete or inconsistent data
- Time points, self-reported data, and data reliant on complex definitions
