Integrating case-based reasoning and hypermedia documentation: an application for the diagnosis of a welding robot at Odense steel shipyard

Reliable and effective maintenance support is a vital consideration for the management within today's manufacturing environment. This paper discusses the development of a maintenance system for the world's largest robot welding facility. The development system combines a case-based reasoning approach for diagnosis with context information, as electronic on-line manuals, linked using open hypermedia technology. The work discussed in this paper delivers not only a maintenance system for the robot stations under consideration, but also a design framework for developing maintenance systems for other similar applications

Planning Support Systems: Progress, Predictions, and Speculations on the Shape of Things to Come

In this paper, we review the brief history of planning support systems, sketching the way both the fields of planning and the software that supports and informs various planning tasks have fragmented and diversified. This is due to many forces which range from changing conceptions of what planning is for and who should be involved, to the rapid dissemination of computers and their software, set against the general quest to build ever more generalized software products applicable to as many activities as possible. We identify two main drivers – the move to visualization which dominates our very interaction with the computer and the move to disseminate and share software data and ideas across the web. We attempt a brief and somewhat unsatisfactory classification of tools for PSS in terms of the planning process and the software that has evolved, but this does serve to point up the state-ofthe- art and to focus our attention on the near and medium term future. We illustrate many of these issues with three exemplars: first a land usetransportation model (LUTM) as part of a concern for climate change, second a visualization of cities in their third dimension which is driving an interest in what places look like and in London, a concern for high buildings, and finally various web-based services we are developing to share spatial data which in turn suggests ways in which stakeholders can begin to define urban issues collaboratively. All these are elements in the larger scheme of things – in the development of online collaboratories for planning support. Our review far from comprehensive and our examples are simply indicative, not definitive. We conclude with some brief suggestions for the future

The nursing contribution to chronic disease management: a whole systems approach: Report for the National Institute for Health Research Service Delivery and Organisation programme

Background Transforming the delivery of care for people with Long Term Conditions (LTCs) requires understanding about how health care policies in England and historical patterns of service delivery have led to different models of chronic disease management (CDM). It is also essential in this transformation to analyse and critique the models that have emerged to provide a more detailed evidence base for future decision making and better patient care. Nurses have made, and continue to make, a particular contribution to the management of chronic diseases. In the context of this study, there is a particular focus on the origins of each CDM model examined, the processes by which nursing care is developed, sustained and mainstreamed, and the outcomes of each case study as experienced by service users and carers. Aims To explore, identify and characterise the origins, processes and outcomes of effective CDM models and the nursing contribution to such models using a whole systems approach Methods The study was divided into three phases: Phase 1: Systematic mapping of published and web-based literature. Phase 2: A consensus conference of nurses working within CDM. Sampling criteria were derived from the conference and selected nurses attended a follow up workshop where case study sites were identified. Phase 3: Multiple case study evaluation Sample: 7 case studies representing 4 CDM models. These were: i) public health nursing model; ii) primary care nursing model; iii) condition specific nurse specialist model; iv) community matron model. Methods: Evaluative case study design with the unit of analysis the CDM model (Yin, 2003): • semi-structured interviews with practitioners, patients, their carers, managers and commissioners • documentary analysis • psycho-social and clinical outcome data from specific conditions • children and young people: focus groups, age-specific survey tools. Benchmarking outcomes: Adults benchmarked against the Health Outcomes Data Repository (HODaR) dataset (Currie et al, 2005). Young people were benchmarked against the Health Behaviour of School aged Children Survey (Currie et al, 2008). Cost analysis: Due to limitations in the available data, a simple costing exercise was undertaken to ascertain the per patient cost of the nurse contribution to CDM in each of the models, and to explore patterns of health and social care utilisation. Analysis: A whole system methodology was used to establish the principles of CDM. i) The causal system is a “network of causal relationships” and focuses on long term trends and processes. ii) The data system recognises that for many important areas there is very little data. Where a particular explanatory factor is important but precise data are lacking, a range of methods should be employed to illuminate each factor as much as possible. iii) The organisational whole system emphasises how various parts of the health and social care system function together as a single system rather than as parallel systems. iv) The patient experience recognises that the whole system comes together and is embodied in the experience of each patient. Key findings While all the models strove to be patient centred in their implementation, all were linked at a causal level to disease centric principles of care which dominated the patient experience. Public Health Model • The users (both parents and children) experienced a well organised and coordinated service that is crossing health and education sectors. • The lead school nurse has provided a vision for asthma management in school-aged children. This has led to the implementation of the school asthma strategy, and the ensuing impacts including growing awareness, prevention of hospital admissions, confidence in schools about asthma management and healthier children. Primary Care Model • GP practices are providing planned and routine management of chronic disease, tending to focus on single diseases treated in isolation. Care is geared to the needs of the uncomplicated stable patient. • More complex cases tend to be escalated to secondary care where they may remain even after the patient has stabilised. • Patients with multiple diagnoses continue to experience difficulty in accessing services or practice that is designed to provide a coherent response to the idiosyncratic range of diseases with which they present. This is as true for secondary care as for primary care. • While the QOF system has clearly been instrumental in developing and sustaining a primary care nursing model of CDM, it has also limited the scope of the model to single diseases recordable on a register, rather than focus on patient centred care needs. Nurse Specialist Model • The model works under a disease focused system underpinned by evidence based medicine exemplified by NICE guidelines and NSF’s. • The model follows a template drawn from medicine and sustainability is significantly dependent on the championship and protectionism offered by senior medical clinicians. • A focus on self-management in LTCs gives particular impetus to nurse-led enablement of self-management. • The shift of LTC services from secondary care to primary care has often not been accompanied by a shift in expertise. Community Matron Model • The community matron model was distinctive in that it had been implemented as a top down initiative. • The model has been championed by the community matrons themselves, and the pressure to deliver observable results such as hospital admission reductions has been significant. • This model was the only one that consistently resulted in open access (albeit not 24 hours) and first point of contact for patients for the management of their ongoing condition. Survey Findings Compared to patients from our case studies those within HODaR visited the GP, practice nurse or NHS walk-in centres more, but had less home visits from nurses or social services within the six weeks prior to survey. HODaR patients also took significantly more time off work and away from normal activities, and needed more care from friends/ relatives than patients from our study within the last six weeks. The differences between the HODaR and case study patients in service use cannot easily be explained but it could be speculated when referring to the qualitative data that the case study patients are benefiting from nurse-led care. Cost analysis – The nurse costs per patient are at least ten times higher for community matrons conducting CDM than for nurses working in other CDM models. The pattern of service utilisation is consistent with the focus of the community matron role to provide intensive input to vulnerable patients. Conclusions Nurses are spearheading the kind of approaches at the heart of current health policies (Department of Health, 2008a). However, tensions in health policy and inherent contradictions in the context of health care delivery are hampering the implementation of CDM models and limiting the contribution nurses are able to make to CDM. These include: ? data systems that were incompatible and recorded patients as a disease entity ? QOF reinforced a disease centric approach ? practice based commissioning was resulting in increasing difficulties in cross health sector working in some sites ? the value of the public health model may not be captured in evaluation tools which focus on the individual patient experience. Recommendations Commissioners and providers 1. Disseminate new roles and innovations and articulate how the role or service fits and enhances existing provision. 2. Promote the role of the nurses in LTC management to patients and the wider community. 3. Actively engage with service users in shaping LTC services to meet patients’ needs. 4. Improve the support and supervision for nurses working within new roles. 5. Develop training and skills of nurses working in the community to enable them to take a more central role in LTC management. 6. Develop organisations that are enabling of innovation and actively seek funding for initiatives that provide an environment where nurses can reach their potential in improving LTC services. 7. Work towards data systems that are compatible between sectors and groups of professionals. Explore ways of enabling patients to access data and information systems for test results and latest information. 8. Promote horizontal as well as vertical integration of LTC services. Practitioners 1. Increase awareness of patient identified needs through active engagement with the service user. 2. Work to develop appropriate measures of nursing outcomes in LTC management including not only bureaucratic and physiological outcomes, but patient-identified outcomes. Implications of research findings 1. Investment should be made into changing patient perceptions about the traditional division of labour, the nurses’ role and skills, and the expertise available in primary care for CDM. 2. Development and evaluation of patient accessible websites where patients can access a range of information, their latest test results and ways of interpreting these. 3. Long-term funding of prospective evaluations to enable identification of CDM outcomes. 4. Mapping of patient experience and patient satisfaction so that the conceptual differences between these two related ideas can be demonstrated. 5. Development of appropriate measures of patient experience that can be used as part of the quality outcome measures. 6. Cost evaluation/effectiveness studies carried out over time that includes national quality outcome indicators and valid measures of patient experience. 7. The importance of whole system working needs to be identified in the planning of services. 8. Research into the role of the health visitor in chronic disease management within a public health model

A Survey on Economic-driven Evaluations of Information Technology

The economic-driven evaluation of information technology (IT) has become an important instrument in the management of IT projects. Numerous approaches have been developed to quantify the costs of an IT investment and its assumed profit, to evaluate its impact on business process performance, and to analyze the role of IT regarding the achievement of enterprise objectives. This paper discusses approaches for evaluating IT from an economic-driven perspective. Our comparison is based on a framework distinguishing between classification criteria and evaluation criteria. The former allow for the categorization of evaluation approaches based on their similarities and differences. The latter, by contrast, represent attributes that allow to evaluate the discussed approaches. Finally, we give an example of a typical economic-driven IT evaluation

Quality of integrated chronic care measured by patient survey: identification, selection and application of most appropriate instruments\ud

Objective  To identify the most appropriate generic instrument to measure experience and/or satisfaction of people receiving integrated chronic care.\ud \ud Background  Health care is becoming more user-centred and, as a result, the experience of users of care and evaluation of their experience and/or satisfaction is taken more seriously. It is unclear to what extent existing instruments are appropriate in measuring the experience and/or satisfaction of people using integrated chronic care.\ud \ud Methods  Instruments were identified by means of a systematic literature review. Appropriateness of instruments was analysed on seven criteria. The two most promising instruments were translated into Dutch, if necessary, and administered to a convenience sample of 109 people with a chronic illness. Data derived from respondents were analysed statistically. Focus-group interviews were conducted to assess the semantic and technical equivalence as well as opinions of people about the applicability and relevance of the translated instruments.\ud \ud Results  From 37 instruments identified, the Patients’ Assessment of Care for chronIc Conditions (PACIC) and the short form of the Patient Satisfaction Questionnaire III (PSQ-18) were selected as most promising instruments. Both instruments produced similar median scores across people with different chronic conditions. The overall PACIC and its subscales and the overall PSQ-18 were highly internally consistent, but not the PSQ-18 subscales. Overall, the PACIC demonstrated better psychometric characteristics. PACIC and PSQ-18 scores were found to be moderately correlated. Whereas more respondents preferred the PSQ-18, focus-group participants regarded the PACIC to be more applicable and relevant. The technical and semantic equivalence of both instruments were sufficient.\ud \ud Conclusions  Because of its psychometric characteristics, perceived applicability and relevance, the PACIC is the most appropriate instrument to measure the experience of people receiving integrated chronic care\u
