perioperative mortality

Death occurring within a defined time period related to surgical intervention, typically 30 or 90 days.

Full Definition

Perioperative mortality refers to patient deaths that occur within a specified timeframe surrounding surgical intervention, most commonly defined as within 30 days of surgery or during the same hospitalization. This metric serves as a critical quality indicator for surgical programs and is used for risk stratification, informed consent discussions, and institutional benchmarking. The definition may extend to 90-day mortality for major oncological procedures where complications may manifest later. Perioperative mortality rates vary significantly based on procedure complexity, patient comorbidities, and institutional factors.

Usage

Usage note: Specify the time period definition (30-day vs 90-day) when reporting rates.
