Comparing the Use of DynaMed and UpToDate by Physician Trainees in Clinical Decision-Making: A Randomized Crossover Trial.

Costs vary substantially among electronic medical knowledge resources used for clinical decision support, warranting periodic assessment of institution-wide adoption. To compare two medical knowledge resources, UpToDate and DynaMed Plus, regarding accuracy and time required to answer standardized clinical questions and user experience. A crossover trial design was used, wherein physicians were randomized to first use one of the two medical knowledge resources to answer six standardized questions. Following use of each resource, they were surveyed regarding their user experience. The percentage of accurate answers and time required to answer each question were recorded. The surveys assessed ease of use, enjoyment using the resource, quality of information, and ability to assess level of evidence. Tests of carry-over effects were performed. Themes were identified within open-ended survey comments regarding overall user experience. Among 26 participating physicians, accuracy of answers differed by 4 percentage points or less. For all but one question, there were no significant differences in the time required for completion. Most participants felt both resources were easy to use, contained high quality of information, and enabled assessment of the level of evidence. A greater proportion of participants endorsed enjoyment of use with UpToDate (23/26, 88%) compared with DynaMed Plus (16/26, 62%). Themes from open-ended comments included interface/information presentation, coverage of clinical topics, search functions, and utility for clinical decision-making. The majority (59%) of open-ended comments expressed an overall preference for UpToDate, compared with 19% preferring DynaMed Plus. DynaMed Plus is noninferior to UpToDate with respect to ability to achieve accurate answers, time required for answering clinical questions, ease of use, quality of information, and ability to assess level of evidence. However, user experience was more positive with UpToDate. Future studies of electronic medical knowledge resources should continue to emphasize evaluation of usability and user experience.

Intention to Use Exoskeletons in Geriatric Care Work: Need for Ergonomic and Social Design

In this research, we investigate user experiences with the Laevo exoskeletons in geriatric work. We introduce two studies where Finnish nurses used exoskeletons and identify the requirements and potential restrictions for using exoskeletons in care context. Our results show that nurses’ intentions to use the exoskeletons were mostly associated with perceived usefulness, ergonomics, and enjoyment of use. Also, social environment issues, such as other people’s reactions, are important considerations. Exoskeleton use has varying requirements depending on where it will be implemented. Thus, the end users’ ideas for the design are crucial in enabling exoskeleton use in different sectors of work.

Current Uptake of Technology Related to the Built Environment to Support Older Adults to Live Independently in Their Community

Current forecasts predict that, in line with increasing global populations and extended life expectancy, older adults will dominate the population structure. To accommodate this demographic shift, governmental policies point to ‘ageing in place’ as key. This article outlines research findings of an initial investigation into the uptake of technology to support ‘ageing in place’. The study sets out to identify both incentives and barriers to the uptake under four key activity criteria— medical, monitoring, mobility and social—at three built environment scales—home, street and neighbourhood, for urban, semi-urban and rural locations—to support older adults to live independently in their community. Results show that whilst there are significant and justified concerns over the limitations of physical conditions to support ‘ageing in place’, most physical conditions along with age are not barriers to the uptake of technology, as uptake is high regardless of circumstances. However, the study revealed that uptake is dependent on level of training, if shown to lead to increasing independence, includes a level of ‘enjoyment of use’, and does not replace existing physical relationships. The study also identified that there is limited research around the use of technology for either mobility or social activities outside the home; rather, research focus is concerned with medical monitoring in the home. Finally, research overlooks the role of geographic demographics to support ‘ageing in place’. The results of this research can provide useful guidelines co-created with older adults for the development of new policies to ‘ageing in place’.

Perceived treadmill function is correlated with enjoyment of use in trained runners: A user-centred approach

Physical inactivity, a primary cause of most chronic diseases, has been associated with low levels of physical activity enjoyment. Physical activity enjoyment can be impacted by an individual's experience with exercise equipment. The purpose of this study was to adopt a user-centred approach to determine the relationship between physical activity enjoyment and functionality and usability of four treadmills. A running protocol was completed by 57 trained runners (41 male) on four treadmills. Runners reported enjoyment levels as well as their perceptions about treadmill running surface, controls, safety and stability, physical interaction, learnability of data console and aesthetic appeal. Repeated measures ANOVAs showed significant differences between the treadmills for each variable. Multiple regression analysis reported aesthetic appeal significantly predicted enjoyment of use. Results suggest that adopting a user-centred approach to compare exercise equipment usability and features can correlate with enjoyment and further impact on physical activity adherence.

The Effects of Knowledge Maps on Acquisition and Retention of Visual Arts Concepts in Teacher Education

This study examined the use of knowledge maps as a tool for teacher education students to increase knowledge acquisition and retention of concepts related to the visual arts design elements: line, color, and shape. Participants were randomly assigned to either the no map or knowledge map group. Three instruments—Student Autobiography, Elements of Design Tests (EDT), and Knowledge Map Questionnaire—were used to collect data. Results revealed significantly higher means on the immediately administered posttest for the elements line and color and the delayed posttest for line map group. Questionnaire responses indicated positive attitudes toward knowledge map use as a study strategy. Specifically, endorsement was reported toward maps’ clarity, effectiveness for learning concepts, and enjoyment of use.

Use of Questioning During Lectures in a Dental Hygiene Didactic Course

The purposes of this quasi-experimental, one-group crossover study were to determine the effect of questioning during dental hygiene lectures on low-level and high-level learning and to evaluate student perceptions of questioning. Twenty-three dental hygiene students participated in two control lectures using traditional lecturing methods. The students served as their own controls by next participating in two experimental lectures with questions asked throughout the lecture at both low and high cognitive levels. Student performance was measured with an examination containing low- and high-level questions. The interaction between the group and the level of questions was analyzed using ANOVA, and no statistically significant difference was found. Based on a Likert scale (1 to 6), average ratings for student perceptions were as follows: enjoyment of use, 4.5; understanding the lecture material, 4.74; and questioning effectiveness, 4.35. Student perceptions of questioning were positive; however, this strategy was found to be no more effective than the traditional lecture in promoting retention of information.

Motivations in personalisation behaviour

A number of emerging technologies including mobile phones and services, on-line shopping and portals, and games and communities are designed to provide users with control over appearance and functioning. Understanding why users personalise could help design personalisation features so that they promote the acceptance and adoption of information and communication technology (ICT). This paper examines the psychological underpinnings of users’ willingness to expend effort to personalise ICT. The important role of the basic need of self-determination [Deci, E.L., Ryan, R.M., 2000. The“what” and “why” of goal pursuits: Human needs and the self-determination of behaviour. Psychological Inquiry 11, 227–268] is argued for. Personalisation features can align the psychological resources with the user’s action and therefore enhance performance and enjoyment of use. First, they can promote autonomy and the sense of being an origin and therefore transform technology to ‘my technology.’ Second, personalisation features can support competence by increasing the effectiveness of user’s actions. At its best, personalisation becomes rewarding activity in itself regardless of the achieved effects, for example when personalisable features participate in flow experiences. Third, through its appearance functions, technology can support the basic need of relatedness through expression of emotion and identity, ego-involvement, and territory marking. Several positive effects can be identified: engagement, performance, persistence, identity, social acceptance, and social status. The paper concludes by discussing implications to design.

Bridging Tools for Human Factors and Design

Poor communication can arise between different professions due to the limitations of the language each specialism employs. Designers, as ‘generalists’, are the end users of ‘specialist’ knowledge such as human factors, but each field will have its own vocabulary of terminology. This communication gap between specialists can result in under-optimised products failing to deliver usability, quality and enjoyment in use. The ambition of this paper is to explore how communication can be improved through the use of a range of ‘bridging tools’ that facilitate the sharing of expertise and the development of a common language between a range of professions, particularly between ergonomists and designers. The paper provides a brief survey of existing bridging tools which facilitate the expression of design issues, and people's rational and emotional responses to design.

Learning to Use the Internet in a Developing Country: Validation of a User Model

This article describes how a model of networked information resource use was used in a study of Internet training for Namibian information workers, and how the study informed the model. The model is based on Ajzen's (1988) theory of planned behaviour and Klobas's (1997) planned behaviour in context (PBiC) model of networked information resource use. The model describes networked information resource use as a function of intention to use a networked information resource such as the Internet or an intranet. It explains how attitudes towards outcomes of use, perceived control of use, social influences, and information resource quality together influence intentions to use a networked information resource. An e-mail survey and questionnaire based on the PBiC model were used to measure attitudes and intended Internet use among participants in a course for Namibian information workers being trained to train others to use electronic information resources. This was the first group to undertake a substantial formal course of Internet user training in Namibia, at a time when Internet access was being extended to towns and rural regions outside the capital city. All trainees referred to the value of the Internet as a source of information, while only one quarter were concerned about potential barriers to use. The trainees' perceptions of Internet quality were mostly positive, with the most appreciated quality being the currency of the information. Perceived ease of use was relatively low. Perceptions of Internet quality appear to have two dimensions reflecting perceptions associated with working with the Internet and with the initial impact of the Internet. Internet quality characteristics associated with initial impact were correlated with intended use, but quality characteristics associated with working with the Internet over time were not correlated with intentions. Ongoing use of the Internet for work reflects attitudes to the Internet more closely than perceived Internet quality characteristics. Attitudes associated with intentions to use the Internet include perceived usefulness in work and career advancement, enjoyment of use, and a sense that all necessary facilities for use are conveniently available. Trainers and educators who are trying to encourage ongoing Internet use among individuals and to promote more widespread use throughout a community should pay attention to developing positive attitudes towards use in their trainees.
