Perioperative mortality

Perioperative mortality refers to death that occurs around the time of a surgical procedure, specifically within 30 days of surgery or during the same hospital stay. It is a key measure of surgical safety and quality of care.

Definition

Perioperative mortality is defined as any death, regardless of cause, occurring within 30 days after surgery in or out of the hospital. It is a standard and widely used indicator in anesthesia, surgery, and health care quality improvement and international comparison.

Risk Factors

Several factors can increase the risk of perioperative mortality. These include patient-related factors such as age, comorbidity, and functional status, as well as procedure-related factors such as the urgency, complexity, and type of surgery. Other factors include the quality of preoperative, intraoperative, and postoperative care.

Prevention

Prevention of perioperative mortality involves careful patient selection, thorough preoperative assessment and optimization, meticulous surgical technique, and vigilant postoperative care. This includes the management of any complications that may arise.

Measurement

Perioperative mortality rates can be measured in various ways, including crude or adjusted rates, observed-to-expected ratios, and risk-adjusted mortality rates. These measures can be used to compare the performance of different hospitals, surgical teams, or health care systems.
