Comparative Congenital Cardiac Catheterization Registry Analysis From the United States and Low- and Middle-Income Countries
Authors' conclusion
The harmonized databases facilitated direct comparison of CCC practices, revealing more complex patients and resource-intensive procedures in C3PO, while the IQIC cohort demonstrated lower CMAE rates but a slightly higher mortality rate. These findings emphasize the need for further risk adjustment modeling for LMICs and identify areas to enhance global resource access and patient outcomes.
Study context
- Population
- Congenital cardiac catheterization procedures recorded in the U.S.-based Catheterization Project on Outcomes (C3PO) registry and the International Quality Improvement Collaborative-Congenital Heart Disease Catheterization Registry (IQIC-CHDCR) registry from low- and middle-income countries (LMICs), 2019 to 2022cases analyzed
- Participants
- 28,957 vs 6,485
- Exposure
- Patient characteristics and outcomes of congenital cardiac catheterization (CCC) in C3PO vs IQIC-CHDCR
- C3POn = 28,957
- IQIC-CHDCRn = 6,485
- Outcome
- Single ventricle patients
