Cost and Return on Healthcare AI: What the Research Actually Shows

Published cost-effectiveness and economic evaluations of healthcare AI. A short list, which is itself the finding.

Here is the uncomfortable result, and it is the reason this subject exists as its own page.

Healthcare AI has tens of thousands of published papers. Formal economic evaluations of it number in the hundreds. So when a vendor tells you the return is proven, the honest response is that the return is mostly modeled, in a handful of use cases, under assumptions somebody chose.

That is not an argument against buying. It is an argument for writing your own business case instead of accepting theirs, and for treating the published economic work as a source of method rather than a source of numbers you can borrow.

The use cases with real economic modeling behind them cluster tightly: screening programs, colonoscopy, retinopathy, and a few imaging workflows. If your use case is not in that cluster, nobody has done the sums yet and the first honest slide in your business case should say so.

What Kind of Evidence This Is

Not every study carries the same weight. This is the mix behind the list below.

What to Measure in Your Own Setting

A published result is somebody else's hospital. These are the numbers worth tracking in yours.

  • Your own baseline first. Most failed business cases are failures of knowing what the process costs today, not failures of the software.
  • Cost per avoided event, not license cost. A cheap tool that changes nothing is the expensive option.
  • The downstream load a tool creates. More detection means more follow-up, and that capacity is rarely in the original budget.
  • Who captures the saving. Time returned to a clinician is only money if something is done with it, and that decision usually sits outside the project.
