Key result
Observed survival following paediatric open-heart surgery was 96.3%, exceeding the expected survival of 94.5% predicted by the RACHS-1 risk model.
Why the study?
Can variable life-adjusted display (VLAD) charts provide an effective method for continuous, prospective performance monitoring of risk-adjusted survival in paediatric cardiac surgery?
Observational (n=460)
Can variable life-adjusted display (VLAD) charts provide an effective method for continuous, prospective performance monitoring of risk-adjusted survival in paediatric cardiac surgery?
Absolute Event Rate: 96.3% vs 94.5%
p-value: p=0.01-0.05
VLAD charts provide an effective, easily visualised graphical method for real-time, risk-stratified outcome analysis and quality assurance in paediatric cardiac surgery.

Observed survival exceeding RACHS-1 predictions supports VLAD for real-time monitoring; leaves open generalizability and practice change.
Kang et al. (2006) conducted an observational in Congenital heart disease requiring surgery (n=460). Paediatric open-heart surgery vs. Expected survival based on RACHS-1 risk model was evaluated on Survival (p=0.01-0.05). Observed survival following paediatric open-heart surgery was 96.3%, exceeding the expected survival of 94.5% predicted by the RACHS-1 risk model.
