Conclusion
A random phenomenon or an algorithmic occurrence, one thing unanimously
agreed upon is that outliers exist, and they are important. In
healthcare, and particularly cardiac surgery, outcome analysis alone may
not be enough to accurately reflect performance. A multifaceted approach
from all relevant stakeholders of healthcare is required to highlight
negative and positive outliers in a fair and sensitive way that promotes
true improvement in performance and clinical standard.
