Purpose of review
This article proposes a standardized framework for colour-coding states of criticality in clinical situations and their respective escalated responses.
Recent findings
The first level is a
green
zone representing a ‘
safe’ space (to proceed)
, where any hazards are controlled, latent or undetectable. The second is an
amber
zone, where hazards are known to be present, but one can
proceed with caution
and increased vigilance, and where defences are used to prevent escalation to a crisis. In the
red
phase -- a state of
crisis
-- a hazard is realized, clear and present. This is a time to decide what actions are required to mitigate the threat. Next, a
blue
phase refers to a
life-threatening emergency
, where the system is unstable, harm is evident and compounding upon itself, and immediate rescue action is needed to avert an irreversible outcome. Finally,
dark grey
represents the
aftermath,
where the situation has either stabilized or progressed to its final outcome, a time to reflect and learn.
Summary
A standardized colour-coding system for assessing and responding to escalating levels of criticality has implications for clinical practice and adverse event reporting systems.
