Patient Safety in Surgical Care

Abstract

The 1999 report of the Institute of Medicine, To Err Is Human: Building a Safer Health System, made national headlines with its estimates of the frequency and severity of adverse events in health care, including that as many as 98,000 medical error–related deaths occur each year in the United States. The observation that the basic principles of human error are highly applicable to clinical practice has markedly advanced our understanding and willingness to address error in this setting. This review seeks to address the characteristics of systems in general and the system of surgical care in particular. It describes the growing knowledge of factors that affect human performance and how these factors contribute to adverse surgical outcomes. The review also outlines current obstacles to improving safety, identifies systems approaches to making improvements, and discusses ways in which surgeons can take the lead in overcoming these obstacles. An overall goal is that acceptance of error and a willingness to investigate its underlying causes will allow health care professionals to make use of the lessons learned from study of nonmedical systems. Tables include definitions of terms related to patient safety, the operation profile, handoff coordination and communication objectives and relevant strategies, nonmedical system techniques applicable to medical systems, Agency for Healthcare Quality and Research patient safety indicators, National Quality Forum list of health care facility–related serious reportable events, and examples of surgically relevant quality improvement practices appropriate for widespread implementation. Figures include the Swiss Cheese Model representing the relationship between latent and active errors and adverse outcomes, a schematic depiction of the process by which system failures may lead to injury, the Systems Engineering in Patient Safety Model of work system and patient safety, and a depiction of contrasting characteristics of medical practice in the 20th and 21st centuries.This review contains 4 figures, 7 tables, and 165 references.
