In healthcare machine learning, most effort is placed on improving model performance.
However, in real-world systems, performance is rarely the primary failure point.
The Core Problem
A model generates predictions.
But healthcare systems require decisions.
This introduces a critical gap between:
model output
clinical action
Where Most Systems Break
No decision mapping
Predictions are not tied to specific clinical actions.
Lack of interpretability
Clinicians cannot validate or trust model outputs.
Workflow misalignment
Predictions are not delivered at the point of decision-making.
Practical Approach
To move from model to impact:
Define decision thresholds with domain context
Implement explainability (e.g., SHAP, feature attribution)
Align outputs with clinical workflows
Validate with real-world scenarios, not just test data
Key Insight
In healthcare, a model is only as valuable as the decision it enables.
Building systems—not just models—is what differentiates strong healthcare data scientists.
