Human Error Theories


Although such high reliability organisations may seem remote from clinical practice, some of their defining cultural characteristics could be imported into the medical domain.Most managers of traditional systems attribute human unreliability to unwanted variability and strive to eliminate it as far as possible. As Reason [1990, p. 51] explained, the "minutia of mental life are governed by a vast community of specialized processors (schemata), each an ‘expert’ in some recurrent aspect of the world, and each operating over brief time spans in response to very specific triggering conditions (activators)." The automatic subsystem appears to have an enormous pool of schemata to activate. Evidence for parallel operation comes from errors that blend aspects of competing plans, such as Spoonerisms [Baars, 1980]. Researchers now agree that both correct performance and errors follow from the same underlying cognitive processes [Reason, 1990, p. 36]. check over here

Human Error Definition

Even with logical attentional thinking, there appears to be schematic organization, just as there is in the automatic subsystem. and Amalberti, R. (2001). It is a model for overall cognition. What if there is no perfect match between the situation and a single schema?

These limitations can easily lead to errors in memory or logical analysis. Blaming individuals is emotionally more satisfying than targeting institutions. Even after people receive training in specific areas, such as physics, they often revert to lay theories afterward [Resnick, 1983]. Human Error Theory In Healthcare Countermeasures are based on the assumption that though we cannot change the human condition, we can change the conditions under which humans work.

Latent conditions have two kinds of adverse effect: they can translate into error provoking conditions within the local workplace (for example, time pressure, understaffing, inadequate equipment, fatigue, and inexperience) and they can create longlasting holes or weaknesses in the defences (untrustworthy alarms and indicators, unworkable procedures, design and construction deficiencies, etc). This, in turn, modifies our schemata. D. & Leveson, N. Privacy policy About Wikipedia Disclaimers Contact Wikipedia Developers Cookie statement Mobile view Theories of Human Error Dr.

The second mechanism is frequency gambling [Reason, 1990]. Causes Of Human Error In The Workplace In: McCauley J, Berkowitz L, editors. The study of absent-mindedness in everyday life provides ample documentation and categorization of such aspects of behavior. JavaScript is disabled on your browser.

The ETTO Principle - Efficiency-Thoroughness Trade-Off. http://orgias.org/human-error/human-error-the-dna-is-doa.html Understanding this leads to proactive rather than reactive risk management. However the limited attentional resources must also be allocated to planning for future actions [Rasmussen, 1990] and dealing with unexpected conditions. ISBN 0-89859-598-3. ^ Hollnagel, E. (1993) Human Reliability Analysis Context and Control. Human Error Prevention

The swamps, in this case, are the ever present latent conditions.Error managementOver the past decade researchers into human factors have been increasingly concerned with developing the tools for managing unsafe acts. Reason J. New York: Basic Books; 1991. 5. this content Weick KE, Sutcliffe KM, Obstfeld D.

But in high tempo or emergency situations, control shifts to the experts on the spot—as it often does in the medical domain. Human Error Models And Management Please review our privacy policy. They anticipate the worst and equip themselves to deal with it at all levels of the organisation.

We flesh them out in parallel with proper syntax, phonemics, and other aspects of speech. High technology systems have many defensive layers: some are engineered (alarms, physical barriers, automatic shutdowns, etc), others rely on people (surgeons, anaesthetists, pilots, control room operators, etc), and yet others depend on procedures and administrative controls. At some point during this process of development, we select a single utterance. James Reason Human Error Such an understanding can provide a helpful framework for a range of risk management activities.PMID: 19416422 DOI: 10.1111/j.1365-2834.2009.00970.x [PubMed - indexed for MEDLINE] SharePublication Types, MeSH TermsPublication TypesReviewMeSH TermsHumansMedical Errors/prevention & control*Medical Errors/psychology*Models, TheoreticalNursing Staff/organization & administrationPsychology, IndustrialRisk Management*LinkOut - more resourcesFull Text SourcesWileyOvid Technologies, Inc.PubMed Commons home PubMed Commons 0 commentsHow to join PubMed CommonsHow to cite this comment: Supplemental Content Full text links You are here: NCBI > Literature > PubMed Support Center Simple NCBI Directory Getting Started NCBI Education NCBI Help Manual NCBI Handbook Training & Tutorials Submit Data Resources Chemicals & BioassaysData & SoftwareDNA & RNADomains & StructuresGenes & ExpressionGenetics & MedicineGenomes & MapsHomologyLiteratureProteinsSequence AnalysisTaxonomyVariation Popular PubMed Bookshelf PubMed Central PubMed Health BLAST Nucleotide Genome SNP Gene Protein PubChem Featured Genetic Testing Registry PubMed Health GenBank Reference Sequences Gene Expression Omnibus Map Viewer Human Genome Mouse Genome Influenza Virus Primer-BLAST Sequence Read Archive NCBI Information About NCBI Research at NCBI NCBI News NCBI FTP Site NCBI on Facebook NCBI on Twitter NCBI on YouTube External link.

The questions are what percentage of errors are detected and corrected and what is the final residual undetected error rate. Resilience engineering: Concepts and precepts. Initially, error research in these specialties evolved in parallel, with only limited cross-fertilization. have a peek at these guys The same set of circumstances can provoke similar errors, regardless of the people involved.

There appear to be no known limits on schemata in long-term memory in terms of either their number or the duration of retention [Reason, 1990, p. 51]. Attentional Control Figure 1 shows that the automatic and attentional subsystems do not work independently.

Hayes and Flower [1980] used protocol analysis to study writing. If something goes wrong, it seems obvious that an individual (or group of individuals) must have been responsible. A great deal of our everyday cognition occurs in the automatic subsystem. Summary pointsTwo approaches to the problem of human fallibility exist: the person and the system approachesThe person approach focuses on the errors of individuals, blaming them for forgetfulness, inattention, or moral weaknessThe system approach concentrates on the conditions under which individuals work and tries to build defences to avert errors or mitigate their effectsHigh reliability organisations—which have less than their fair share of accidents—recognise that human variability is a force to harness in averting errors, but they work hard to focus that variability and are constantly preoccupied with the possibility of failurePerson approachThe longstanding and widespread tradition of the person approach focuses on the unsafe acts—errors and procedural violations—of people at the sharp end: nurses, physicians, surgeons, anaesthetists, pharmacists, and the like.

Such heuristics and biases are strategies that are useful and often correct, but can lead to systematic patterns of error. Because of parallelism, our automatic subsystem is extremely fast. Reason [1990] argues that there appear to be two core mechanisms for selecting schemata to be activated.
