This measure is calculated based on data extracted from the electronic medical record. This measure is explicitly not based on provider self-attestation.
Percentage of patients with in hospital death reported within 30 days after procedure.
Anesthesia Start to 30 days after Anesthesia End
All patients undergoing anesthesia
Patients without an inpatient death documented within 30 days after anesthesia
# of cases where pt died in hospital within 30 days of procedure (exclude subsequent cases, only count one case per pt) / total # of cases (count all cases, do not exclude if multiple cases per pt)
Institutional measure - individual provider attribution not applicable
Percentage of Cases with Patient Mortality within 30 Days
Over 2.3 million surgeries occur worldwide per year, making perioperative mortality ratios (POMR) an important metric of surgical and anesthetic safety.3,4,6 Mortality rates can also identify failure to rescue in the healthcare system.3,4,6,7 In hospital mortality rates within 30 days of surgery in the United States are estimated to have fallen from 1.64%-1.68% in 1996 to 1.14%-1.32% in 2006, however there is no consensus on acceptable POMR within 30 days or surgery or day of surgery.2,5,6 Variance in 30 day POMR are indicative of overall health system and surgical safety, while variance in same day POMR are more likely to capture differences in decisions to operate, anesthetic and procedural care, and ability to care for a deteriorating patient intra and postoperatively.1,3 POMR should be calculated as a ratio where the numerator is the number of patients who died within 30 days after a procedure and the denominator is all procedures/cases.1,3,6 Calculating the ratio in this way represents the risk associated with each surgical case.3 This measure should not be used to compare institutions, but rather to guide quality improvement.6
