Percentage of patients, ≥18 years age, who undergo open cardiac surgical procedures under general anesthesia of 120 minutes duration or longer for whom last non-artifact body temperature measure at the end of the case was not greater than or equal to 35.5 degrees Celsius (or 95.9 degrees Fahrenheit). (Reported as an inverse measure: lower is better.)
Perioperative hypothermia is defined as a core temperature less than 36 degrees Celsius by both the National Institute of Health and Clinical Excellence and the American Heart Association.1,2 It is not uncommon for a patient’s core temperature to drop during surgery due to anesthetic induced peripheral vasodilation, exposure of skin during the surgical prep or impaired heat distribution. Perioperative hypothermia can result in multiple adverse effects including surgical site infections, cardiovascular events, impaired wound healing and increased hospital length of stay in both the non-cardiac3-9 and cardiac surgical populations.10-19 Such adverse effects are prevented through maintenance of normothermia intraoperatively,3-4 yet, specifically in the cardiac surgical setting hyperthermia is also detrimental and should be avoided.10-13,15,18,19
30 minutes before Cardiopulmonary Bypass End through 30 minutes after Anesthesia End (for cases without bypass: use 30 minutes before anesthesia start time to 30 minutes after anesthesia end time)
All patients, 18 years of age or older, who undergo open cardiac surgical procedures (as determined by Procedure Type: Cardiac phenotype) under general anesthesia of 120 minutes duration or longer.
Last non-artifact body temperature measure at anesthesia end greater than or equal to 35.5 degrees Celsius (or 95.9 degrees Fahrenheit), prioritizing core temperature measurements.
Temperatures will be assessed as follows: (Flowchart version)
Not applicable.
Any provider signed in for ≥40 minutes from bypass end until anesthesia end. If the measure time period is less than 40 minutes, the provider signed in for the greatest number of minutes during this period (per staff role) will be attributed.
If bypass was not used, the window would be expanded to any provider signed in for ≥40 minutes for the entire case.
In the event that two or more providers in the same class are signed in for the same duration, all providers signed in for the longest duration will be attributed.
