A threshold is a clinical decision, not just a number
An electronic monitor triggers an alert when a measurement crosses a configured value. If the threshold is inappropriate for the patient group or setting, important deterioration may be missed or staff may face excessive false alarms.
Define the intended population
A threshold validated in one clinical context may not perform the same way in another. Review relevant evidence and approved local clinical governance.
Understand sensitivity and specificity
Changing a threshold can alter the balance between missed events and unnecessary alerts. Neither extreme is automatically safest.
Assess the complete workflow
An alert is useful only if measurements are reliable, messages reach the right team and appropriate action follows.
Review patient-specific considerations
Individual circumstances may require professional assessment and authorised configuration under institutional policy.
Test before widespread change
Evaluate proposed adjustments with appropriate clinical, technical and safety oversight rather than changing settings merely to reduce alert volume.
Monitor unintended effects
Review false alarms, missed deterioration, response burden and clinical outcomes after implementation.
Break-test: fewer alarms, more missed events
Does the team recognise that reduced notification volume is not necessarily better patient safety?
