To Err Is Human Building a Safer Health System

In 1974 an article appeared in Science magazine with the dry-sounding title “Judgment Under Uncertainty: Heuristics and Biases” by a pair of psychologists who were not well known outside their discipline of decision theory. In it Amos Tversky and Daniel Kahneman introduced the world to Prospect Theory, which mapped out how humans actually behave when faced with decisions about gains and losses, in contrast to how economists assumed that people behave. Prospect Theory turned Economics on its head by demonstrating through a series of ingenious experiments that people are much more concerned with losses than they are with gains, and that framing a choice from one perspective or the other will result in decisions that are exactly the opposite of each other, even if the outcomes are monetarily the same. Prospect Theory led cognitive psychology in a new direction that began to uncover other human biases in thinking that are probably not learned but are part of our brain’s wiring.

Thinking fast and slow.

The power of feedback.

SUMMARY Review date: 1969 to 2003, 34 years. Background and context: Simulations are now in widespread use in medical education and medical personnel evaluation. Outcomes research on the use and effectiveness of simulation technology in medical education is scattered, inconsistent and varies widely in methodological rigor and substantive focus. Objectives: Review and synthesize existing evidence in educational science that addresses the question, ‘What are the features and uses of high-fidelity medical simulations that lead to most effective learning?’. Search strategy: The search covered five literature databases (ERIC, MEDLINE, PsycINFO, Web of Science and Timelit) and employed 91 single search terms and concepts and their Boolean combinations. Hand searching, Internet searches and attention to the ‘grey literature’ were also used. The aim was to perform the most thorough literature search possible of peer-reviewed publications and reports in the unpublished literature that have been judged for academic quality. Inclusion and exclusion criteria: Four screening criteria were used to reduce the initial pool of 670 journal articles to a focused set of 109 studies: (a) elimination of review articles in favor of empirical studies; (b) use of a simulator as an educational assessment or intervention with learner outcomes measured quantitatively; (c) comparative research, either experimental or quasi-experimental; and (d) research that involves simulation as an educational intervention. Data extraction: Data were extracted systematically from the 109 eligible journal articles by independent coders. Each coder used a standardized data extraction protocol. Data synthesis: Qualitative data synthesis and tabular presentation of research methods and outcomes were used. Heterogeneity of research designs, educational interventions, outcome measures and timeframe precluded data synthesis using meta-analysis. Headline results: Coding accuracy for features of the journal articles is high. The extant quality of the published research is generally weak. The weight of the best available evidence suggests that high-fidelity medical simulations facilitate learning under the right conditions. These include the following:

Anesthesia crisis resource management: Real-life simulation training in operating room crises

Improving anesthesiologists' performance by simulating reality.

A recent report from the Institute of Medicine has focused attention anew on the incidence of medical errors in the health care industry. While there is a relatively large body of research on how organizations can operate in a highly reliable manner, and thus avoid such errors, little of that work has been done in the health care field. This article discusses the ways in which the health care industry has failed to meet systematically the standards for achieving high reliability, based in part on two existing theories about the management of high-hazard environments-High Reliability Organization Theory (HROT) and Normal Accidents Theory (NAT).

Structural and Organizational Issues in Patient Safety: A Comparison of Health Care to Other High-Hazard Industries

Objective. To describe the development of an instrument for assessing workforce perceptions of hospital safety culture and to assess its reliability and validity.

Data Sources/Study Setting. Primary data collected between March 2004 and May 2005. Personnel from 105 U.S. hospitals completed a 38-item paper and pencil survey. We received 21,496 completed questionnaires, representing a 51 percent response rate.

Study Design. Based on review of existing safety climate surveys, we developed a list of key topics pertinent to maintaining a culture of safety in high-reliability organizations. We developed a draft questionnaire to address these topics and pilot tested it in four preliminary studies of hospital personnel. We modified the questionnaire based on experience and respondent feedback, and distributed the revised version to 42,249 hospital workers.

Data Collection. We randomly divided respondents into derivation and validation samples. We applied exploratory factor analysis to responses in the derivation sample. We used those results to create scales in the validation sample, which we subjected to multitrait analysis (MTA).

Principal Findings. We identified nine constructs, three organizational factors, two unit factors, three individual factors, and one additional factor. Constructs demonstrated substantial convergent and discriminant validity in the MTA. Cronbach's α coefficients ranged from 0.50 to 0.89.

Conclusions. It is possible to measure key salient features of hospital safety climate using a valid and reliable 38-item survey and appropriate hospital sample sizes. This instrument may be used in further studies to better understand the impact of safety climate on patient safety outcomes.

Workforce Perceptions of Hospital Safety Culture: Development and Validation of the Patient Safety Climate in Healthcare Organizations Survey

Objectives: To determine participant perceptions of Emergency Medicine Crisis Resource Management (EMCRM), a simulation-based crisis management course for emergency medicine. Methods: EMCRM was created using Anesthesia Crisis Resource Management (ACRM) as a template. Thirteen residents participated in one of three pilot courses of EMCRM; following a didactic session on principles of human error and crisis management, the residents participated in simulated emergency department crisis scenarios and instructor-facilitated debriefing. The crisis simulations involved a computer-enhanced mannequin simulator and standardized patients. After finishing the course, study subjects completed a horizontal numerical scale survey (1 = worst rating to 5 = best rating) of their perceptions of EMCRM. Descriptive statistics were calculated to evaluate the data. Results: The study subjects found EMCRM to be enjoyable (4.9 ± 0.3) (mean ± SD) and reported that the knowledge gained from the course would be helpful in their practices (4.5 ± 0.6). The subjects believed that the simulation environment prompted realistic responses (4.6 ± 0.8) and that the scenarios were highly believable (4.8 ± 0.4). The participants reported that EMCRM was best suited for residents (4.9 ± 0.3) but could also benefit students and attending physicians. The subjects believed that the course should be repeated every 8.2 ± 3.3 months. Conclusions: The EMCRM participants rated the course very favorably and believed that the knowledge gained would be beneficial in their practices. The extremely positive response to EMCRM found in this pilot study suggests that this training modality may be valuable in training emergency medicine residents.
