Key result
Common definitions of intraoperative hypotension predicted the administration of antihypotensive medication with 54% to 67% accuracy, correlating poorly with anaesthetists' clinical judgement.
Why the study?
Do common definitions of intraoperative hypotension predict the administration of antihypotensive medication in a mixed surgical population?
Observational (n=2,350)
Do common definitions of intraoperative hypotension predict the administration of antihypotensive medication in a mixed surgical population?
Common definitions of intraoperative hypotension correlate poorly with the actual administration of antihypotensive medication by anaesthetists, who consider multiple perioperative factors beyond just systolic blood pressure.

May warrant caution against BP-threshold–only triggers; leaves open refined definitions validated against clinical judgement.
Franck et al. (2011) conducted an observational in Intraoperative hypotension (n=2,350). Definitions of intraoperative hypotension was evaluated on Accuracy of predicting antihypotensive medication administration. Common definitions of intraoperative hypotension predicted the administration of antihypotensive medication with 54% to 67% accuracy, correlating poorly with anaesthetists' clinical judgement.
