Why System Design Matters More Than Model Performance in Healthcare ML

In healthcare ML, improving model performance is often the primary focus.

However, real-world success depends on system design.

The Problem

Models are built in isolation.
Healthcare systems are not.

System Components

A functional healthcare AI system includes:

data pipelines
model outputs
decision logic
workflow integration
Common Mistake

Optimizing models without considering:

where outputs are used
how decisions are made
who interacts with the system
Practical Approach
design end-to-end systems
define decision pathways
integrate with existing infrastructure
Key Insight

In healthcare, systems—not models—determine impact.
