Perioperative Safety Overview

Principles

Definition

Perioperative safety is a multidisciplinary research field and clinical discipline focused on minimizing preventable harm and optimizing outcomes for patients undergoing surgical and anesthetic procedures. It involves the systematic investigation, identification, analysis, and mitigation of risks across the pre-operative, intra-operative, and post-operative phases through the application of evidence-based practices, standardized protocols, technological integration, and system-level improvements. Drawing upon frameworks that incorporate learning from both failures and successes (e.g., Safety I, II, III), this field emphasizes the development of rigorous guidelines, consensus-based measures, and robust analytics to enhance the reliability and quality of perioperative care.

Data-Driven Surveillance era

Robert A. Caplan [1] operated during the Data-Driven Surveillance era (1982–1995) with appointments at Harvard University [3] and the University of Washington [4]. Caplan [1] highlighted the paper "Role of Monitoring Devices in Prevention of Anesthetic Mishaps" [6] (1989), illustrating how monitoring devices enabled automated detection and standardized reporting of perioperative hazards, a core advance for this era. Frederick W. Cheney [2] contributed to data-driven safety through affiliations with the University of Washington [4] and Seattle University [5], promoting surveillance-based benchmarking across institutions. Cheney [2] also included the paper "Role of Monitoring Devices in Prevention of Anesthetic Mishaps" [6] (1989) among his era contributions, demonstrating how device-based surveillance supported nationwide reporting and risk benchmarking.

Risk-Based Standardization era

Lee A. Fleisher [1], Harvard University [3], and University of California, San Francisco [4], played a central role in risk-based perioperative care during 1996–2009. His contributions include the 1996 Guidelines for perioperative cardiovascular evaluation for noncardiac surgery [8], the 2002 ACC/AHA guideline update for perioperative cardiovascular evaluation for noncardiac surgery—executive summary [6], and the 2007 Guidelines on Perioperative Cardiovascular Evaluation and Care for Noncardiac Surgery [7], which helped standardize risk stratification and care pathways. Hugh Calkins [2], Harvard University [3], and Stanford University [5], contributed to risk-based standardization of perioperative care during this era. His papers—the 2002 executive summary [6], the 2007 guidelines [7], and the 2009 ACCF/AHA Focused Update on Perioperative Beta Blockade Incorporated Into the ACC/AHA 2007 Guidelines on Perioperative Cardiovascular Evaluation and Care for Noncardiac Surgery [9]—advanced perioperative risk assessment and beta-blockade guidance, reinforcing the era's focus on risk management and standardized protocols.

Guideline Implementation era

Lena M. Napolitano [1], affiliated with University of California, San Francisco [3] and Stanford University [4], emerges in the Guideline Implementation era (2010–2023) as a leading voice in perioperative safety. Lena M. Napolitano [1] contributed to the 2013 Clinical practice guidelines for antimicrobial prophylaxis in surgery [6], offering evidence-based recommendations that standardize perioperative antimicrobial timing and selection, a cornerstone for implementation efforts in this era. Robert A. Weinstein [2], associated with Harvard University [5] and University of California, San Francisco [3], coauthored the same antimicrobial prophylaxis guidelines [6], demonstrating cross-institutional collaboration that anchored guideline dissemination and pragmatic uptake. These combined efforts show how guideline-driven optimization and dissemination in 2010–2023 underpinned health-system quality-improvement programs and routine perioperative practice across preoperative, intraoperative, and postoperative stages [6].
