This measure is calculated based on data extracted from the electronic medical record combined with administrative data sources such as professional fee and discharge diagnoses data. This measure is explicitly not based on provider self-attestation.
Percentage of cases where intraoperative hypotension (MAP < 55 mmHg) was sustained for less than 20 minutes.
Intraoperative. See ‘Other Measure Build Details’ for more information
All patients requiring general anesthesia or monitored anesthesia care (MAC).
Algorithm for determining Measure Start/End Times:
Measure Start Time:
First Blood Pressure Reading after the latest of these 3 times:
* For labor epidurals which convert to cesarean deliveries where the procedures are combined under one case ID, 'Cesarean Delivery Start Time' is used as the 'Measure Start Time'
Measure End Time:
* For labor epidurals which convert to cesarean deliveries where the procedures are combined under one case ID, the latest 'data capture end' is used as the 'Measure End Time' when appropriate (all other cases use logic from 'Data Capture End' phenotype)
All providers for a given case whose individual cumulative MAP < 55mmHG exceeds the 20 minute timeframe

Intraoperative hypotension is associated with compromised organ perfusion and puts patients at risk for post-operative mortality, cardiac adverse events (CAEs), acute kidney injury, and stroke. Multiple studies have demonstrated the association of a decreased mean arterial pressure and postoperative morbidity and mortality. One retrospective review included 33,000 non-cardiac surgical patients and determined that a mean arterial pressure less than 55mmHG predicted CAEs and adverse renal-related outcomes6. This was confirmed by a distinct investigation of 5000 patients using invasive blood pressure measurement5.
