Why LLMs in Healthcare Aren't the Cure-All We Thought

Large language models (LLMs) are creeping into healthcare systems, selling the promise of revolutionizing how we handle electronic health records. But here's the kicker: they're not cutting it. While static benchmarks tell us if they're correct, they don't get to the heart of user acceptance. And let's be honest, if doctors don't trust it, they're not using it.

The Real Test: User Acceptance

A recent study put an LLM system under the microscope in an academic medical center, and it highlights a big gap. Instead of merely checking if the model is right, researchers evaluated how likely users were to reject its suggestions. Over 4.5 months, they tracked user feedback and discovered something essential: user rejection could be predicted with an AUROC of 0.719. But here's the twist, it's not just about the query content. Context is king.

By considering factors like provider type, department name, and even the specific language model, the study found a more accurate way to forecast if users would reject the system's output. It seems the devil really is in the details.

What's Next? Guardrails and Beyond

So, what's the play? With this insight, we can forge better guardrails. Imagine a system that knows when to step back, all because it understands its own context. These predictions could trigger guardrails or even decide when to abstain altogether. Does this sound like a band-aid for a bigger issue? Maybe. But it's a start.

Here's the elephant in the room: why are these models still struggling with user trust? If nobody would play it without the model, the model won't save it. Trust and user comfort need to be top of mind, or we're just spinning our wheels.

Why You Should Care

Why does this matter to you, the reader? Well, it’s healthcare. It’s about precision and trust. If LLMs can’t win over the skeptics, they won’t be saving any time or lives. And if you're in the industry, understanding these nuances can help you better deploy or even sell these technologies. But remember, the game comes first. The economy comes second.

Bottom line? Without user trust, the fanciest AI model in the world is just a parlor trick. Retention curves don't lie. If LLMs want to be a staple in healthcare, they need to be more than just correct. They need to be wanted.
