In fact, a recent PwC study found that nearly 40% of healthcare executives are already using generative AI to improve clinical workflows and operations. That number is only going up.

So what does this mean for hospitals, researchers, and patients?

This guide breaks down the real impact of generative AI in healthcare. Where it is being used, how it is making a difference, and what challenges still need to be solved. Whether you are part of a health system, medtech firm, or AI startup, understanding this shift is not optional. It is essential.

What Is Generative AI and Why It Matters in Healthcare

Generative AI refers to a type of artificial intelligence that creates new content based on patterns it learns from existing data. It can generate text, images, summaries, or even suggest medical insights. Unlike traditional AI, which follows rules or classifications, generative AI adapts, predicts, and produces relevant outputs in real time.

So why does this matter for healthcare?
