{"title":"Exploratory analysis of deviations from formal procedures during preoperative anaesthetic evaluation","authors":"P. Vassilakopoulou, Vassilis Tsagkas, N. Marmaras","doi":"10.1145/1962300.1962330","DOIUrl":"https://doi.org/10.1145/1962300.1962330","url":null,"abstract":"Motivation --- The aim of this paper is to study deviations from formal procedures during preoperative anaesthetic evaluation and to investigate their possible association with the assumptions that anaesthesiologists make during the evaluation. The findings of this analysis can be applied for the identification of requirements and limitations for the standardisation of the task through supporting tools. Research approach --- Records of 100 consecutive preanaesthesia evaluations for elective surgery in a private hospital were retrospectively analysed. In addition, field observations were carried out in order to guide data collection and support the formulation of an initial framework for organizing our findings. This way, data analysis and fieldwork were interwoven, feeding each other. Findings/Design --- The review of 100 preanaesthesia evaluation records revealed that a significant number of them deviated from the normative course of action. Specifically, contrary to the stipulations of the prescribed procedure, in 26% of our cases, the evaluation was performed without having available the preoperative laboratory test results. Furthermore, the form provided for the documentation of the evaluation was scarcely filled-in (75% of the forms had less than 30 out of the 83 total fields completed. In the same time, free-text fields were extensively used, spilling over their content to other fields in 15% of the cases. Our findings are consistent with prior research which indicates that routine laboratory tests are not critical for the evaluation of the patient. Furthermore, the frequently completed fields coincide with the main findings of previous research on the opinions of anaesthesiologists regarding what variables they consider as important. A possible explanation for the observed deviations from formal procedures and low utilisation of standardized forms could be that anaesthesiologists are engaged in a thinking-acting process rather than in a process of information collection directed by a protocol. Standardisation efforts through supporting tools ought to be non-obstructive to this process. Research limitations/Implications --- Our research is limited by the modest sample size of 100 cases and input from a single hospital. Nevertheless, the questions raised and initial hypotheses formulated can be further tested with a larger sample size and different medical establishments. Originality/Value --- Anaesthesiologists have been leaders in applying lessons from Human Factors and Cognitive Ergonomics, but most effort was directed to the development of support tools and decision aids for the operating theatre. The research presented here aims at extending those lessons to the preanaesthesia related tasks. Take away message --- Deviations from the formal procedure during preoperative anaesthetic evaluation can be used for the identification of requirements and limitations for the standardisation of the task through supporting tools.","PeriodicalId":115733,"journal":{"name":"Proceedings of the 28th Annual European Conference on Cognitive Ergonomics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131952908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to create such a learning environment, knowledge about 'typical social behavior' and 'ASD deviations in social behavior' will be modelled. The main propositions, for which some evidence already exists, are that (1) interaction with (robotic) technology is free of social tension for children with ASD and (2) this can therefore, by removing inhibitions, aid the acquisition and training of social skills, and, moreover (3), that these skills can be transferred and used productively in social interaction with other humans.","PeriodicalId":115733,"journal":{"name":"Proceedings of the 28th Annual European Conference on Cognitive Ergonomics","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115190361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unless properly managed it leads to life-threatening events, increasing disabilities, and death. Due to the essential role of lifestyle in the development of CHD, patients are in a large part able to self-manage their disease. Internet-based self-management tools and services hold the promise to support patients and their caregivers in this task. Research approach -- This study aims to identify the needs and preferences of CHD patients in daily self-management challenges. An exploratory qualitative research method, originating from the field of product design, will be used to explore self-management needs of CHD patients. As a preparation to this study a literature study, four interviews and a pilot study were executed. Findings/Design -- Based on the literature study and the interviews, two different research tools were designed. These tools were tested in a pilot study. From August to October inclusive the research tools will be adjusted and the study will be executed, resulting in a description of health related self-management needs for patients with CHD. Take away message -- New opportunities for prevention of disease and health self-management arise through internet-based applications. Qualitative research methods involving patients, originating from the field of product design can contribute to the optimal development of such applications.","PeriodicalId":115733,"journal":{"name":"Proceedings of the 28th Annual European Conference on Cognitive Ergonomics","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114360179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bonnardel","doi":"10.1145/1962300.1962317","DOIUrl":"https://doi.org/10.1145/1962300.1962317","url":null,"abstract":"This study contributes to a better understanding of how the use of different tools influences both the design process and the way that final designs are assessed. Unlike previous research comparing computer aided design (CAD) and freehand sketching, we compared CAD and manual modelling. CAD systems and manual modelling both tend to be used after the early design stage, which is mainly involves sketching. Our study would therefore be useful for determining which of the two is more appropriate, depending on the designer's priorities and the intended purpose of the object being developed. Our study was conducted in two phases. First the activities of 20 designers were recorded in two different experimental conditions: 1) using a CAD system 2) using manual modelling. Secondly, 20 other participants (judges) were asked to assess the end results of these activities. According to the experimental condition, we observed differences in both the design activities and the assessments of the final designs. More specifically, items designed using a CAD system were scored higher on aesthetics, originality and marketing. However, no difference was observed for the functionality criterion. Use of a CAD system would appear to be most appropriate for highlighting aesthetic and marketing features, but manual modelling remains a suitable tool for designing functional objects.","PeriodicalId":115733,"journal":{"name":"Proceedings of the 28th Annual European Conference on Cognitive Ergonomics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123682747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This allows access to a wide field of view, up to a range of 260° (Chen, Solinger, Poncet & Lancet, 1999). The recent increase in large displays places a demand on being able to track a mobile user's gaze over this extensive range. Research approach -- We developed an extensible system for measuring the gaze of users on wall-sized displays. Our solution combines the inputs of a conventional head-mounted eyetracker (Eyelink2©, SR Research) and motion-capture system (Vicon MX©, Vicon), to provide real-time measurements of a mobile user's gaze in 3D space. Findings/Design -- The presented system serves as a single platform for studying user behavior across a wide range of tasks: single-step saccade shifts, free-viewing of natural scenes, visual search and gaze-assisted user interfaces. Importantly, it allows eye- and head-movements to be separately measured without compromising the accuracy of combined gaze measurements. Take away message -- Unrestrained gaze movements on a large display can be accurately measured by suitably combining the inputs of conventional eye- and body-tracking hardware.","PeriodicalId":115733,"journal":{"name":"Proceedings of the 28th Annual European Conference on Cognitive Ergonomics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130325481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using robot for this is a new and we want to find out what the advantages or disadvantages could be. Research approach -- By using non-invasive wireless sensors the health of the person can be monitored. In case of a possible problem, like when the person has fallen, a robot can autonomously go to the person and ask or check whether help from care-providers would be needed. This check could avoid many false alarms. The robot can call a care-provider by itself. The control of the robot can also be taken over by a care-provider to enable telepresence. By communicating with the person though the robot and seeing through the camera of the robot, the care-provider can then better evaluate the situation and help remotely or send help directly. Findings/Design -- The sensors, the robot and the interaction will be designed and evaluated by doing user-tests. Privacy-issues will be investigated too. Take away message -- The use of such a Home Care Robot can be very cost-effective because it enables people to live longer in their own home, it can prevent many false alarms for the care-provider and compared to systems that need cameras everywhere it can offer more privacy.","PeriodicalId":115733,"journal":{"name":"Proceedings of the 28th Annual European Conference on Cognitive Ergonomics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130706527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ajovalasit","doi":"10.1145/1962300.1962344","DOIUrl":"https://doi.org/10.1145/1962300.1962344","url":null,"abstract":"Motivation -- Task workload is key determinant of human performance. It may include physical and/or cognitive components, and these can interact to influence operator performance. This research study investigates the interaction of physical workload, mental workload and arousal level on attentional resources in order to predict performance. Research approach -- This study was divided into two experiments. In both experiments, fifteen participants (aged 25--35) performed a physical task (pedalling on a bicycle-ergometer) concurrently with a mental task under nine levels of workload in a 3x3 design (low, medium and high levels for both physical and mental). In the first experiment, the mental task was designed to occupy verbal attentional resources through mental arithmetic, whereas a spatial figures task was used in the second experiment to evaluate spatial resources. Findings/Design -- The hypothesis of the study is that optimum performance occurs at intermediate levels of workload, whereas poor performance is observed at the extreme low and high levels of physical and mental demand due to underload and overload. It is also anticipated that physical and mental workload can interact to 'offset' underload or overload decrements. Originality/Value -- The present study will fill the gap in the ergonomics literature by explaining performance degradation due to mental underload and by clarifying the interaction with physical workload. Take away message -- It is possible that moderate levels of physical workload could compensate for attentional resource reduction with mental underload.","PeriodicalId":115733,"journal":{"name":"Proceedings of the 28th Annual European Conference on Cognitive Ergonomics","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128065869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
