Insights
The Pediatric Acute Care Cardiology Collaborative (PAC3) registry demonstrates high accuracy (99.27%) in clinical data, supporting its use for quality improvement and research. Both regional and virtual audit methods proved effective and were well-received by participants.
Area of Science:
- Cardiology
- Health Informatics
- Clinical Data Management
Background:
- The Pediatric Acute Care Cardiology Collaborative (PAC3) aimed to enhance pediatric acute care cardiology outcomes via a validated clinical registry.
- This study reports on the validation of initial PAC3 registry audits and introduces a novel regional audit format.
- The audit format was adapted for expanding membership, collaborative learning, and COVID-19 pandemic modifications.
Purpose of the Study:
- To validate the accuracy of the PAC3 clinical registry through comprehensive audits.
- To assess the effectiveness of a novel regional audit format and virtual audits.
- To confirm the registry's suitability for quality improvement, benchmarking, and research.
Main Methods:
- Nine hospitals participated in the audit process, utilizing both regional and virtual audit formats.
- Audits focused on critical and challenging data elements within at least 40 randomly selected patient cases per hospital.
- Discrepancies were categorized as major or minor, with results tabulated and reported.
Main Results:
- A total of 386 encounters and 27,086 data fields were audited across nine hospitals.
- The aggregate overall accuracy rate was 99.27%, with a major discrepancy rate of 0.51%.
- Accuracy rates ranged from 98.77% to 99.59%, and major discrepancy rates from 0.26% to 0.88%; no significant difference was observed between audit formats.
Conclusions:
- The PAC3 registry is a highly accurate data source, suitable for quality improvement, benchmarking, and research.
- Both regional and virtual audit methodologies were successfully implemented and viewed favorably by participants.
- The findings support the reliability of the PAC3 registry for advancing pediatric acute care cardiology.
Background:
The Pediatric Acute Care Cardiology Collaborative (PAC3) was established to improve acute care cardiology outcomes through the development of an accurate and well-validated clinical registry. We report the validation results of the initial PAC3 registry audits and describe a novel regional audit format developed to accommodate a rapidly expanding membership facilitate collaborative learning and allow for necessary modification due to the COVID-19 pandemic.
Materials And Methods:
Six hospitals were audited using a regional audit format and three hospitals were subsequently audited virtually. Critical and challenging-to-collect data elements were audited among at least 40 randomly selected cases. Discrepancies were categorised as either major or minor depending on their relative importance to patient outcomes and clinical care. Results were tabulated and reported.
Results:
We audited 386 encounters and 27,086 individual data fields across 9 hospitals. The aggregate overall accuracy rate was 99.27% and the aggregate major discrepancy rate was 0.51%. The overall accuracy rate ranged from 98.77% to 99.59%, and the major discrepancy rate ranged from 0.26% to 0.88% across the cohort. No appreciable difference was seen between audit formats. Both the regional and virtual audit methods were viewed favourably by participants.
Conclusions:
A low data discrepancy rate was found demonstrating that the PAC3 registry is a highly accurate data source for use in quality improvement, benchmarking, and research. Regional audits and virtual audits were both successfully implemented.
