critical result

A critical result is an examination finding that indicates a potentially serious patient condition requiring prompt clinical attention according to agreed criteria. It is not simply any result outside a reference interval. Laboratories define critical thresholds or findings with appropriate clinical input, taking account of the examination, patient group, service arrangements, and relevant professional guidance.

A critical-result procedure specifies identification, any appropriate checking, authorized recipients, communication methods, escalation when contact fails, and documentation. Verification steps should not create avoidable delay. Record enough detail to show the result communicated, the patient concerned, the time, the sender, and the recipient, with confirmation of understanding where appropriate. Electronic alerts need evidence that the required communication pathway works rather than an assumption that transmission equals receipt.

Accreditation assessment focuses on whether urgent information reliably reaches someone able to act. Test escalation arrangements outside normal hours and review delayed or failed notifications. Keep thresholds and recipient pathways current with clinical services. Monitoring notification performance can reveal weaknesses that routine reporting statistics miss, especially during staff changes, system outages, or referral arrangements.
