This paper briefly discusses the subject of human error in health care systems and presents a comprehensive list of references on the said subject.
This paper through a systematic view considers the subject of Airplane — Flight crew system, as an intricate system of Man and Machine. And we study its Reliability on Flight Safety with an emphasis on Human factor. Aiming at the above goals.
As we define the constituents of the system from a Socio-Technical perspective, introduce main factors involved in brining about Human errors in such a system. Finally we discuss the methods and procedures for the reduction of these errors which leads eventually to the promotion of Human reliability and consequently the Flight Safety.
A framework for human error modes and effects analysis is presented. The methods of hierarchical task analysis and event tree analysis are introduced as the basic analytical tools, and a novel generic framework for human errors classification is presented as the guidance to identify human errors. Firstly, the process of human error modes and effects analysis is discussed, and the hierarchical task analysis method is introduced briefly. Secondly, the framework for human errors classification is discussed in detail. Thirdly, the multi-states event tree is designed to model the accident scenario. Finally, two scenarios are selected as the examples to illustrate the proposed process of human error modes and effects analysis.
Electrophysiological correlates of human reliability in visual response tasks were investigated in 16 healthy subjects using electroencephalographic (EEG) spectral power and event-related potentials (ERP). Human reliability was first determined by calculating individual reaction accuracy in order to split the entire group into high reliability (HR) and low reliability (LR) subgroups, each with eight subjects. The EEG activities of testing subjects were measured at rest condition for 5 min, and during a modified Eriksen flanker task. Artifact-free EEG segments were used to compute the distribution of EEG at varied frequency bands as well as to detect peak and latency of ERPs of the flanker task. Our results showed that subjects with LR exhibited higher alpha band EEG power at the frontal recording site. Additionally, LR group revealed lower P300 amplitude and predominantly longer P300 latency at centro-parietal recording site than those of the HR group. These findings implied that higher alpha band EEG power at frontal and smaller amplitude, longer latency P300 component of ERP measures at centro-parietal might reveal the trait of lower reliability in healthy controls during visual tasks.
