Impact Of Operator Experience Research Articles

Impact of operator experience on information feedback and reusability

Keeping a record of operator experience remains a challenge to operation management and a major source of inefficiency in information management. The objective is to develop a framework that enables an explicit presentation of experience based on information use. A purposive sampling method is used to select four small and medium-sized enterprises as case studies. The unit of analysis is the production process in the machine shop. Data collection is by structured interview, observation and documentation. A comparative case analysis is applied. The findings suggest experience is an accumulation of tacit information feedback, which can be made explicit in information use interoperatability matrix. The matrix is conditioned upon information use typology, which is strategic in waste reduction. The limitations include difficulty of participant anonymity where the organisation nominates a participant. Areas for further research include application of the concepts to knowledge management and shop floor resource management.

CMR endpoints for clinical trials: impact of operator experience on the accuracy of image analysis

Methods 20 CMR studies of acute coronary syndromes were included in this study. 6 observers with three levels of training conducted the image analysis: Observers 1+4: expert SCMR level 3 operators; Observers 2+5: trainees with SCMR level 2 experience; Observers 3+6: a cardiologist and a clinical trial coordinator with no previous CMR experience. The latter level underwent a 4hr tutorial on how to use the software on 10 practice cases. All 6 observers analysed 20 studies, and re-analysed 10 studies 24 hours after. Volumes and mass were analysed using semi-automated software (Argus, Siemens), infarct size (IS) was manually planimetered using a 2SD threshold.

A study on the impact of operator experience on the patient radiation exposure in coronary angiography examinations

The aim of the current study was to investigate the effect of cardiologists' experience on the patient received dose during coronary angiography. The exposure parameters including fluoroscopy time, total kerma-area product (KAP), total air-kerma, fluoroscopy and cine acquisition KAP and air-kerma for five senior cardiologists with the experience of 6-10 y were recorded. The range of values for fluoroscopy time and total KAP were 2.17- 4.19 min and 12.06-21.06 Gy cm(2), respectively, in our diagnostic coronary examinations, which was below the recommended reference values. The differences among cardiologists were analysed statistically using one-way ANOVA test. The fluoroscopy KAP and air-kerma results showed statistically significant differences between cardiologists. However, the experience of the cardiologists showed no relation with patient received dose. According to the results, training in radiation protection as a requisite for interventional cardiologists was recommended.
