The Institute of Medicine’s (IOM's) report, To Err Is Human: Building a Safer Health System (Kohn, Corrigan, & Donaldson, 2000), was a catalyst for a national effort to make health care safer in the United States. The IOM’s goals for healthcare system reform included viewing errors as learning tools, enacting legislation to protect voluntary reporting of medical errors, setting performance standards and expectations for patient safety, and implementing safety systems in healthcare organizations (Kohn et al.). The report stimulated an array of stakeholders to engage in patient safety initiatives. Healthcare organizations instituted safer practices, agencies and professional societies issued safety guidelines and recommendations, increased funding was dedicated to patient safety research, the Joint Commission issued national patient safety goals, and patient safety legislation was introduced. However, despite those efforts, health care was not measurably safer in 2005 than it was in 2000. In fact, data suggest that the magnitude of the problem of preventable healthcare errors may be substantially underestimated. Many errors continue to go unreported, so the true incidence is unknown. The use and effectiveness of safety measures also are unknown because reliable outcome measures are lacking. Advances to impact patient safety that are expected to occur from 2005–2010 include increased use of technology to reduce errors, wide dissemination of an array of safety practices, increased training for teamwork, and full disclosure of errors. However, barriers to progress include the culture and complexity of health care, continuing skepticism that system failures are the underlying cause of most healthcare errors, and fear of malpractice liability that inhibits the willingness to discuss or even admit errors (Kalisch & Aebersold, 2006; Leape & Berwick, 2005).
The Agency for Healthcare Research and Quality (2003) described healthcare errors as mistakes made in the process of care that result in or have the potential to result in harm to patients. The errors may be of commission (i.e., doing the wrong thing), omission (i.e., not doing the right thing), or execution (i.e., doing the right thing incorrectly). Healthcare errors can be grouped into four general categories: diagnostic errors, treatment errors, preventive care errors, and errors involving failure, such as communication, equipment, and healthcare system failure.
Patient safety is defined by the National Patient Safety Foundation (2003) as "the prevention of healthcare errors and the elimination or mitigation of patient injury caused by healthcare errors." Patient safety is influenced by workplace conditions, such as staffing, work flow, individual and group personal and social factors, the physical environment, and organizational factors (Page, 2004). In the field of oncology, environmental factors that impact patient safety include multiple individuals involved in the care of a single patient, the high acuity of patients with cancer, and the complexity of cancer treatment. Despite clinicians' best efforts, errors can occur inadvertently when an unfortunate confluence of individual, workplace, communication, technologic, and organizational factors occurs. The nature of cancer treatment creates a very conducive environment for errors even with the involvement of well-intentioned, experienced, highly educated healthcare providers.
