What is clinical data?

Definition

Clinical data can include diagnoses, laboratory measurements, imaging, treatments, outcomes and observations from trials or routine care. It provides evidence about how diseases and interventions behave in people rather than only in simplified models.

High-quality clinical data is difficult to collect and interpret because populations, measurements and care settings vary. Privacy, consent, bias and missing information must be managed before data is used to train or evaluate artificial intelligence systems.

Frequently asked questions

Why is clinical data important for medical AI?

It provides evidence about real patients and outcomes that cannot be recovered reliably from general internet text or purely computational predictions.

What limits the use of clinical data?

Privacy obligations, consent, inconsistent records, selection bias, missing values and differences among populations can limit access and generalization.
