Computer mediated colour fidelity and communication

Developments in technology have meant that computercontrolled imaging devices are becoming more powerful and more affordable. Despite their increasing prevalence, computer-aided design and desktop publishing software has failed to keep pace, leading to disappointing colour reproduction across different devices. Although there has been a recent drive to incorporate colour management functionality into modern computer systems, in general this is limited in scope and fails to properly consider the way in which colours are perceived. Furthermore, differences in viewing conditions or representation severely impede the communication of colour between groups of users. The approach proposed here is to provide WYSIWYG colour across a range of imaging devices through a combination of existing device characterisation and colour appearance modeling techniques. In addition, to further facilitate colour communication, various common colour notation systems are defined by a series of mathematical mappings. This enables both the implementation of computer-based colour atlases (which have a number of practical advantages over physical specifiers) and also the interrelation of colour represented in hitherto incompatible notations. Together with the proposed solution, details are given of a computer system which has been implemented. The system was used by textile designers for a real task. Prior to undertaking this work, designers were interviewed in order to ascertain where colour played an important role in their work and where it was found to be a problem. A summary of the findings of these interviews together with a survey of existing approaches to the problems of colour fidelity and communication in colour computer systems are also given. As background to this work, the topics of colour science and colour imaging are introduced

Changing practice in dementia care in the community: developing and testing evidence-based interventions, from timely diagnosis to end of life (EVIDEM)

Background Dementia has an enormous impact on the lives of individuals and families, and on health and social services, and this will increase as the population ages. The needs of people with dementia and their carers for information and support are inadequately addressed at all key points in the illness trajectory. Methods The Unit is working specifically on an evaluation of the impact of the Mental Capacity Act 2005, and will develop practice guidance to enhance concordance with the Act. Phase One of the study has involved baseline interviews with practitioners across a wide range of services to establish knowledge and expectations of the Act, and to consider change processes when new policy and legislation are implemented. Findings Phase 1, involving baseline interviews with 115 practitioners, identified variable knowledge and understanding about the principles of the Act. Phase 2 is exploring everyday decision-making by people with memory problems and their carers

Transitions at the end of life for older adults - patient, carer and professional perspectives

BackgroundThe end of life may be a time of high service utilisation for older adults. Transitions between care settings occur frequently, but may produce little improvement in symptom control or quality of life for patients. Ensuring that patients experience co-ordinated care, and moves occur because of individual needs rather than system imperatives, is crucial to patients’ well-being and to containing health-care costs.ObjectiveThe aim of this study was to understand the experiences, influences and consequences of transitions between settings for older adults at the end of life. Three conditions were the focus of study, chosen to represent differing disease trajectories.SettingEngland.ParticipantsThirty patients aged over 75 years, in their last year of life, diagnosed with heart failure, lung cancer and stroke; 118 caregivers of decedents aged 66–98 years, who had died with heart failure, lung cancer, stroke, chronic obstructive pulmonary disease or selected other cancers; and 43 providers and commissioners of services in primary care, hospital, hospice, social care and ambulance services.Design and methodsThis was a mixed-methods study, composed of four parts: (1) in-depth interviews with older adults; (2) qualitative interviews and structured questionnaire with bereaved carers of older adult decedents; (3) telephone interviews with care commissioners and providers using case scenarios derived from the interviews with carers; and (4) analysis of linked Hospital Episode Statistics (HES) and mortality data relating to hospital admissions for heart failure and lung cancer in England 2001–10.ResultsTransitions between care settings in the last year of life were a common component of end-of-life care across all the data sets that made up this study, and many moves were made shortly before death. Patients’ and carers’ experiences of transitions were of a disjointed system in which organisational processes were prioritised over individual needs. In many cases, the family carer was the co-ordinator and provider of care at home, excluded from participation in institutional care but lacking the information and support to extend their role with confidence. The general practitioner (GP) was a valued, central figure in end-of-life care across settings, though other disciplines were critical of GPs’ expertise and adherence to guidelines. Out-of-hours services and care homes were identified by many as contributors to unnecessary transitions. Good relationships and communication between professionals in different settings and sectors was recognised by families as one of the most important influences on transitions but this was rarely acknowledged by staff.ConclusionsDevelopment of a shared understanding of professional and carer roles in end-of-life transitions may be one of the most effective ways of improving patients’ experiences. Patients and carers manage many aspects of end-of-life care for themselves. Identifying ways to extend their skills and strengthen their voices, particularly in hospital settings, would be welcomed and may reduce unnecessary end-of-life transitions. Why the experiences of carers appear to have changed little, despite the implementation of a range of relevant policies, is an important question that has not been answered. Recommendations for future research include the relationship between policy interventions and the experiences of end-of-life carers; identification of ways to harmonise understanding of the carers’ role and strengthen their voice, particularly in hospital settings; identification of ways to reduce the influence of interprofessional tensions in end-of-life care; and development of interventions to enhance patients’ experiences across transitions.FundingThe National Institute for Health Research Health Services and Delivery Research programme
