Trial criteria are coarse by design. Reasoned departure — in either direction — is legitimate: ASSET records your reasoning, it does not override it. The decision to refer / treat rests with the treating clinicians.

ASSET needs a connection. Use the usual referral route.

What ASSET is for

ASSET is a clinician support tool. It checks a patient against the published eligibility criteria of the thrombectomy trials and shows what those trials found, so the evidence can be reviewed in a structured way. It does not replace clinical judgement: treatment decisions remain entirely at the discretion of the treating clinicians.

Trial criteria are coarse by design. They describe trial populations, not individual patients, each of whom has a unique infarct, physiological reserve and clinical course. Some patients outside the criteria may benefit from thrombectomy, and some within them may not.

Reasoned departure is legitimate. Departing from eligibility thresholds — in either direction — can be a valid, evidence-aware clinical decision that protects patients from falling between the trials. NICE NG128 asks clinicians to “take into account the person’s overall clinical status and the extent of established infarction on initial brain imaging to inform decisions about thrombectomy” (recommendation 1.4.8).
Documenting, not overriding. ASSET is designed to facilitate, support and record your clinical reasoning — not to enforce a prescribed action. The decision to refer remains with the primary treating clinician. Decisions on eligibility against trial criteria, and on technical feasibility, remain at the discretion of the treating interventional neuroradiologist (INR).
