Percentage of cases where intraoperative hypotension (MAP < 65 mmHg) was sustained for less than 15 minutes
Intraoperative hypotension (MAP < 65mmHg) is associated with compromised organ perfusion and puts patients at risk for post-operative mortality, cardiac adverse events (CAEs) and acute kidney injury (AKI). Multiple studies have addressed the impact of hypotension on patient outcomes and generally show less CAEs, AKI, and death by maintaining a MAP above 60-70mmHg.1,2 One retrospective cohort analysis, including 57,315 non-cardiac surgical patients, demonstrated a MAP of less than 65mmHg was associated with a higher incidence of myocardial and kidney injury and the duration of low MAP significantly increases the odds of the aforementioned outcomes.3 Furthermore, a retrospective review including 33,330 non-cardiac surgical patients determined that a MAP less than 65mmHg for any duration was associated with similar adverse outcomes4
Intraoperative. See ‘Other Measure Build Details’ for more information
All patients requiring anesthesia, general, neuraxial, monitored anesthesia care (MAC), or regional.
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)
Not applicable.
All providers for a given case whose individual cumulative MAP < 65mmHG exceeds the 15-minute timeframe.
