From first concepts to Diasonograph: The role of product design in the first medical obstetric ultrasound machines in 1960s Glasgow.

In the late 1950s and early-to-mid-1960s, Glasgow led the world in the development of diagnostic obstetric ultrasound technology, the result of fortuitous collaboration between key individuals advancing the application of an industrial technology. Originally used to detect flaws in metal pressure vessels, the obstetrician Ian Donald, during his military service, reflected on how ultrasound could benefit his own field. Donald involved the engineer Tom Brown to tackle the technical challenges. Brown, in turn, employed a young graduating industrial designer, Dugald Cameron, to address the design, aesthetic and ergonomic aspects of these early engineering prototypes. While previous accounts of these developments have rightly celebrated the medical, technical engineering and imaging achievements of this innovative technology, the discussion of the role of the creative design expertise which addressed serious ergonomic, aesthetic and production manufacturing shortcomings of the first prototypes has been less coherent. This article relates, through key drawings, extracts from witness statements and discussions with Cameron himself, the key design decisions and features resulting in the Sundén and Diasonograph machines, the latter being the world's first commercial production-series obstetric ultrasound machine, deployed in Glasgow hospitals and beyond.

Rehabilitation professionals' perceptions of the use of new visualisation software tools with people with stroke.

PURPOSE: The envisage programme of research was funded to explore and evaluate the use of visualisation software tools using biomechanical data within rehabilitation. Three work packages were developed to evaluate the impact of the tools within stroke rehabilitation. The research presented here aimed at exploring the perceptions of rehabilitation therapists about the use of the visualisation software tools in the context of future randomised controlled trials and stroke rehabilitation practice. METHODS: Sixteen therapists working in a range of stroke rehabilitation contexts participated in semi-structured interviews. Interview questions explored their current practice, and the perceived impact of the new visualisation technologies on their workplace environment and practice. Framework analysis was used to analyse the textual data. RESULTS: In general, the stroke therapists were enthusiastic about the potential application of the visualisation software tools. Three themes were identified through qualitative framework analysis: potential uses of the visualisation tools; integration within current service provision; and trial involvement. CONCLUSIONS: The study highlights important contextual considerations which may impact significantly on the success of novel technologies in stroke rehabilitation. Normalisation process theory was proposed as a useful process evaluation methodology to optimise both trial evaluation and future service implementation. Implications for Rehabilitation There is limited research exploring the use of visual software technologies featuring biomechanical data within stroke rehabilitation. The perspectives of stroke rehabilitation therapists about the potential of such tools are useful both in terms of planning trial evaluations, and implementation. Therapists were generally positive about the contribution of visual software tools in stroke rehabilitation, but highlighted a number of practical constraints which required addressing. Normalisation process theory provides a useful process evaluation methodology which can support both trial evaluation and implementation of such novel technologies within stroke rehabilitation.

Developing visualisation software for rehabilitation: investigating the requirements of patients, therapists and the rehabilitation process.

This article describes the ongoing process of engaging with users in the development and evaluation of prototype visualisation software, which aims to assist in the understanding and improvement of appropriate movements during rehabilitation. The value of the process is illustrated in the article with a discussion of the key findings of pre-pilot focus groups with stroke survivors and therapists. The article describes how the design of the visualisation software is being adapted to meet the emerging understanding of the needs of patients and professionals, and of the rehabilitation process.

Hospitalfoodie: an interprofessional case study of the redesign of the nutritional management and monitoring system for vulnerable older hospital patients.

BACKGROUND: To date, a solution to the problem of hospital malnutrition in older patients in the UK has not been found through previous approaches using isolated interventions. AIMS: To identify opportunities for, and to develop and prototype a new food and nutritional management system able to meet individual patients' daily requirements. METHODS: Using an interprofessional team approach, design researchers worked alongside food scientists, dieticians, medical sociologists, ergonomists, computer scientists, technologists, key stakeholders and a 'food family' (those concerned with nutrition management, and food supply and delivery in hospital, i.e. food producers, caterers, ward staff, nurses dieticians, physicians, speech and occupational therapists), as well as with older people representatives. Through ethnography and workshop-based methods, major opportunities for service improvement were identified. An iterative design and development process was deployed using mixed methods including ethnography, mapping, personas, storyboarding, role-playing, enactment and narratives. Prototypes of interactive interfaces were developed to test the workability of an electronic nutritional management and monitoring system linked to a nutrition composition database. In parallel, new food products were developed, led by food scientists, and a catering supply and delivery system for ward-based food provision was also developed. The methods used to facilitate interprofessional collaboration, the engagement of the food family, and to develop the food and nutrition service concept are described. RESULTS: A demonstration prototype was displayed in exhibition format at a series of conferences to gather further feedback. CONCLUSION: Early responses to the 'hospitalfoodie' demonstration prototype were favourable and indicate that, with further development, the prototype may offer the means for improving nutritional care standards in hospitals and be adaptable for use across other patient groups.
