Quality outcomes of ACHD patients undergoing cardiovascular procedures and hospital admissions in a free-standing children's hospital.

Objectives: Describe quality outcomes of adults with congenital heart disease (ACHD) undergoing cardiovascular procedures and admissions in a free-standing children's hospital with a multi-disciplinary ACHD program and compared with pediatric outcomes.

Background: A challenge for the U.S. healthcare system is where to treat the >1 million ACHD patients (pts): adult hospitals without CHD care, or pediatric hospitals without adult services.

Methods: We reviewed all CHD pts ≥ 18 yrs of age from 2002-2007. Procedural and hospital related morbidity and mortality were recorded. ANOVA and t-test compared adult with pediatric pts.

Results: Overall, 782 pts, mean age of 29.8 ± 9.9 yrs, encountered 1490 procedures/admissions. For 178 cardiac surgeries (72% reoperations), mortality was 1.8% and complication rate was 7.3%. There was 0% mortality for 412 cardiac catheterizations, 311 electrophysiological procedures, 401 transesophageal echocardiograms (TEE), 244 exercise tests (ETT) and 54 medical admissions. Major adverse event rate was 0.6% for cardiac catheterization and electrophysiological procedures. No adverse events occurred during TEE and ETT. Only 4 pts required transfer to an adult institution (0.25%). There was no significant difference in mortality or adverse events between pediatric and adult CHD pts, p>0.05.

Conclusions: The optimal setting to provide ACHD care remains a complex issue. Our study is the first to demonstrate 1) a low incidence of morbidity and mortality for ACHD pts undergoing cardiovascular procedures or admissions at a free-standing children's hospital, 2) outcomes comparable to pediatric CHD pts. Future models incorporating ACHD programs within pediatric heart centers should be considered to care for this complex population.
