New hardware platforms for healthcare consultations

Innovative hardware platforms such as Mobile Clinical Assistants and tabletop computers are emerging that have the potential to significantly impact the interaction between clinician and patient. This position paper describes the results of interviews undertaken with General Practitioners as part of an experimental study to explore how innovative hardware platforms impact patient-clinician communication. We reflect on the lessons learnt from the study, both in terms of the implications for the design of such studies and possible directions for the introduction of new hardware technologies into healthcare consultations

An Exploratory Study into the Accessibility of a Multi-User Virtual World for Young People with Aphasia

This paper describes an exploratory study into the accessibility of the virtual world Second Life for two young people with aphasia. Aphasia is a communicative disorder most commonly caused by a stroke. It affects both written and spoken language, is frequently accompanied by right-sided paralysis and people with aphasia can experience isolation and social exclusion. Multi-user virtual worlds are a potential source of fun and contact with others, but how accessible are such worlds to those with communication issues? We report an investigation into the accessibility and potential of Second Life for people with aphasia. This was accomplished through a critique and an empirical study involving two young people: Ann was in her mid twenties and Bob in his early thirties. They were selected because both were comfortable with computer technologies before their strokes and each continues to use them, albeit in a more limited capacity. We discuss implications of the results for people with aphasia interacting with multi-user virtual worlds

PaperChain: A Collaborative Healthcare System Grounded in Field Study Work

In this extended abstract we summarise our recent experiences of designing and deploying PaperChain, a system to support real-time information sharing in healthcare work. A guiding principle has been the development of a deep understanding of the work as the foundation for effective system design. We summarise the field work that motivated the development of PaperChain, some of the key findings and the resulting system. We briefly reflect on the benefits gained from undertaking substantial HCI work in the design of a healthcare system

Thermal tides in an assimilation of three years of Thermal Emission Spectromenter data from Mars Global Surveyor

Introduction. Thermal tides are particularly prominent in the Mars atmosphere with the result that temperature and wind fields have a strong dependence on local solar time (LT). Tides include westward propagating migrating (sun-synchronous) waves driven in response to solar heating and additional nonmigrating waves resulting from zonal variations in the thermotidal forcing. Zonal modulation of forcing can arise from longitudinal variations of the boundary (topography and surface thermal inertia) and radiatively active aerosols (dust and water ice clouds). Nonmigrating tides appear as diurnally varying upslope/ downslope circulations within the near-surface boundary layer that, like their migrating counterparts, are also able to propagate vertically to aerobraking altitudes in the lower thermosphere. The Mars Global Surveyor (MGS) Thermal Emission Spectrometer (TES) has yielded atmospheric temperature profiles with unprecedented latitude and longitude coverage that has provided the basis for characterizing the seasonal evolution of tides and stationary waves [1]. However, the twice-daily observations (2 am and 2 pm LT) are insufficient to unambiguously resolve the sunsynchronous tides. Recently the technique of data assimilation has been sufficiently developed for Mars to yield a dynamically consistent set of thermal and dynamic fields suitable for detailed investigations of various aspects of the martian circulations system [2,3,4,5]. We will refer to this data set an the TES Reanalysis, which represents the current best estimate of the evolving state of the martian atmosphere during the MGS mission. The assimilated thermal and dynamical fields provide a means of assessing circulation variability and transport capability reflecting the variability of the actual Mars atmosphere

Characterization, cloning and immunogenicity of antigens released by lung-stage larvae of Schistosoma mansoni

Lung-stage schistosomula are the target of protective immunity in mice vaccinated with attenuated cercariae of Schistosoma mansoni. Therefore, proteins present at this developmental stage, and in particular those which are secreted, are a potential source of novel vaccine candidates. However, little information is available about such molecules. Here we describe the cDNA clones identified by screening expression libraries with serum raised against proteins released by lung-stage schistosomula. In total, 11 different cDNA species were identified, 6 of which have been described previously in S. mansoni; these included fructose 1,6-bisphosphate aldolase and Sm21.7 which together accounted for two-thirds of all positive clones. Of the 5 newly described schistosome genes, 1 cDNA had a high degree of homology to the s5a subunit of 26S proteasomes, most significant being with the human protein. The remaining 4 clones showed no significant homologies to any genes sequenced previously. Fructose 1,6-bisphosphate aldolase, Sm21.7, the proteasome homologue and 1 unknown clone (A26) have been expressed in a bacterial expression system and serum produced against each recombinant protein. Immunolocalization showed fructose 1,6-bisphosphate aldolase, Sm21.7 and the proteasome homologue to be most abundant in muscle cells whilst clone A26 was distributed throughout many tissues, but was most abundant in the tegument. Analysis of the cellular immune responses of vaccinated mice showed 3 of the 4 expressed clones to be highly immunogenic, inducing the secretion of large quantities of the Th1-type cytokine interferon gamma

A pragmatics' view of patient identification

Patient identification is a central safety critical aspect of healthcare work. Most healthcare activities require identification of patients by healthcare staff, often in connection with the use of patient records. Indeed, the increasing reliance on electronic systems makes the correct matching of patients with their records a keystone for patient safety. Most research on patient identification has been carried out in hospital settings. The aim was to investigate the process of identification of patients and their records in the context of a primary healthcare clinic

Public yet private: the status, durability and visibility of handover sheets

Drawing on data from a multi-site case study of a range of clinical settings, this paper explores the form of nursing handover sheets and the processes through which they are created and updated. We argue that these documents function as both public and private documents, having relevance for the whole ward while also acting as a personal workspace. Such dual functionality needs to be supported by any technology that seeks to provide for the work of handover, if the handover sheet is to continue to act as a space for work, rather than just a repository of information
