Why the study?

Intraoperative hypotension prediction methods mitigate low blood pressure exposure time, but they have not convincingly demonstrated improved objective outcomes and have recently become controversial.

Implication

Low PPV warrants cautious clinical use of predictions; leaves open the need for individualized and treatment-effect modeling.

Structured PICO

I
Intervention
Intraoperative hypotension prediction methods

Current intraoperative hypotension prediction methods show good sensitivity but low positive predictive value, and future research should focus on tailoring predictions to individual patients and predicting treatment effects.
