Machine learning approach applied to human activity recognition – an application to the VanKasteren dataset

Reminders are a core component of many assistive technology systems and are aimed specifically at helping people with dementia function more independently by compensating for cognitive deficits. These technologies are often utilized for prospective reminding, reminiscence, or within coaching-based systems. Traditionally, reminders have taken the form of nontechnology based aids, such as diaries, notebooks, cue cards and white boards. This article is based on the use of machine learning algorithms for the detection of Alzheimer’s disease. In the experimentation, the LWL, SimpleLogistic, Logistic, MultiLayerPercepton and HiperPipes algorithms were used. The result showed that the LWL algorithm produced the following results: Accuracy 98.81%, Precission 100%, Recall 97.62% and F- measure 98.80

The Meaning and Experience of Gratitude for People Living with Dementia

RationaleSupporting people to live well with dementia is an international government priority. People living with dementia experience a range of positive emotions despite the challenges associated with dementia. Further research is needed to explore how these positive experiences can be fostered to support well-being. There is empirical evidence of the benefits of gratitude in other clinical groups, but no studies have explored how gratitude is experienced by people living with dementia.MethodsIn this mixed-methods study, eight people living with dementia shared their experiences of gratitude through interviews and gratitude diaries. Qualitative data were analysed using interpretative phenomenological analysis. Quantitative data regarding diary use were analysed using descriptive statistics.Findings and ConclusionsGratitude holds interpersonal and transpersonal meanings for people living with dementia, balanced with challenges of dementia and ageing. This study offers insight into the existence and relevance of gratitude for people living with dementia, highlighting the importance of using multiple methods in dementia research. Positive psychology interventions informed by these findings may be effective in supporting well-being for people with dementia

Towards improved decision support in the assessment and management of pain for people with dementia in hospital: a systematic meta-review and observational study

This is the final version. Available from NIHR Journals Library via the DOI in this record.Background Pain and dementia are common in older people, and impaired cognitive abilities make it difficult for them to communicate their pain. Pain, if poorly managed, impairs health and well-being. Accurate pain assessment in this vulnerable group is challenging for hospital staff, but essential for appropriate management. Robust methods for identifying, assessing and managing pain are needed. Aims and objectives Two studies were undertaken to inform the development of a decision support tool to aid hospital staff in the recognition, assessment and management of pain. The first was a meta-review of systematic reviews of observational pain assessment instruments with three objectives: (1) to identify the tools available to assess pain in adults with dementia; (2) to identify in which settings they were used and with what patient populations; and (3) to assess their reliability, validity and clinical utility. The second was a multisite observational study in hospitals with four objectives: (1) to identify information currently used by clinicians when detecting and managing pain in patients with dementia; (2) to explore existing processes for detecting and managing pain in these patients; (3) to identify the role (actual/potential) of carers in this process; and (4) to explore the organisational context in which health professionals operate. Findings also informed development of health economics data collection forms to evaluate the implementation of a new decision support intervention in hospitals. Methods For the meta-review of systematic reviews, 12 databases were searched. Reviews of observational pain assessment instruments that provided psychometric data were included. Papers were quality assessed and data combined using narrative synthesis. The observational study used an ethnographic approach in 11 wards in four UK hospitals. This included non-participant observation of 31 patients, audits of patient records, semistructured interviews with 52 staff and four carers, informal conversations with staff and carers and analysis of ward documents and policies. Thematic analysis of the data was undertaken by the project team. Results Data from eight systematic reviews including 28 tools were included in the meta-review. Most tools showed moderate to good reliability, but information about validity, feasibility and clinical utility was scarce. The observational study showed complex ward cultures and routines, with variations in time spent with patients, communication patterns and management practices. Carer involvement was rare. No pain decision support tools were observed in practice. Information about pain was elicited in different ways, at different times, by different health-care staff and recorded in separate documents. Individual staff made sense of patients’ pain by creating their own ‘overall picture’ from available information. Limitations Grey literature and non-English-language papers were excluded from the meta-review. Sample sizes in the observational study were smaller than planned owing to poor documentation of patients’ dementia diagnoses, gatekeeping by staff and difficulties in gaining consent/assent. Many patients had no or geographically distant carers, or a spouse who was too unwell and/or reluctant to participate. Conclusions No single observational pain scale was clearly superior to any other. The traditional linear concept of pain being assessed, treated and reassessed by single individuals did not ‘fit’ with clinical reality. A new approach enabling effective communication among patients, carers and staff, centralised recording of pain-related information, and an extended range of pain management interventions is proposed [Pain And Dementia Decision Support (PADDS)]. This was not tested with users, but a follow-on study aims to codesign PADDS with carers and clinicians, then introduce education on staff/patient/carer communications and use of PADDS within a structured implementation plan. PADDS will need to be tested in differing ward contexts.National Institute for Health Research Health Services and Delivery Research programm

When technology cares for people with dementia:A critical review using neuropsychological rehabilitation as a conceptual framework

Clinicians and researchers have become increasingly interested in the potential of technology in assisting persons with dementia (PwD). However, several issues have emerged in relation to how studies have conceptualized who the main technology user is (PwD/carer), how technology is used (as compensatory, environment modification, monitoring or retraining tool), why it is used (i.e., what impairments and/or disabilities are supported) and what variables have been considered as relevant to support engagement with technology. In this review we adopted a Neuropsychological Rehabilitation perspective to analyse 253 studies reporting on technological solutions for PwD. We analysed purposes/uses, supported impairments and disabilities and how engagement was considered. Findings showed that the most frequent purposes of technology use were compensation and monitoring, supporting orientation, sequencing complex actions and memory impairments in a wide range of activities. The few studies that addressed the issue of engagement with technology considered how the ease of use, social appropriateness, level of personalization, dynamic adaptation and carers' mediation allowed technology to adapt to PWD's and carers' preferences and performance. Conceptual and methodological tools emerged as outcomes of the analytical process, representing an important contribution to understanding the role of technologies to increase PwD's wellbeing and orient future research.University of Huddersfield, under grants URF301-01 and URF506-01

Assessment of Occupational Competence in Dementia: Identifying Key Components of Cognitive Competence and Examining Validity of the Cognitive Competency Test

Considering the links between dementia and everyday living, occupational therapists are called upon to make recommendations regarding appropriate living arrangements for persons with dementia. Re-framed as occupational competence, this is often accomplished by an evaluation of cognitive competence. Within the context of an aging population, a key question is how to best inform decisions regarding occupational competence, using cognitive competence as an indicator. The Cognitive Competency Test (CCT) is a tool used to evaluate cognitive competence and inform judgments about occupational competence in individuals with dementia. This thesis incorporates two studies that identified cognitive components that predict occupational competence in individuals with dementia, and examined the construct validity of the CCT, using a framework developed by Samuel Messick. A Delphi study, conducted amongst Canadian occupational therapists with experience in dementia care, generated a consensus regarding the components of cognitive competence essential to predict occupational competence in persons with dementia. A second study employed a retrospective chart review and examined the dimensional structure of the CCT and its relationship with other clinical measures typically used in dementia care. Occupational therapists identified ten cognitive components essential to predict occupational competence in individuals with dementia. The structure of the CCT is a unitary factor that demonstrates correlations to some clinical measures commonly used in dementia care. These findings give some support to the validity of the CCT and have implications for development of new measures and education regarding cognitive competence, pointing to the need to address other factors identified in the Delphi

Homes for Life & Other Stories The Use and Evaluation of Design Fiction as a Means to Understand Sensitive Settings: a Case Study of Exploring Technologies for Dementia Care

Design fictions are used in HCI to position emerging technologies in fictional future worlds, through which the complexities of our relationships with technologies can be represented, explored and experienced. They promise to stimulate discussions about sensitive topics, such as the future of technology-enabled care, a complex area with contrasting emotional, social and practical views and wishes. However, the term design fiction is currently associated with a wide range of uses, and artefacts. It is also linked to contrasting philosophies and frameworks, which are often not made explicit, as I show in an initial survey with practitioners. This makes it difficult to identify what makes a design fiction good or effective for different purposes. This thesis aims to answer the research question: How can design fiction be used and evaluated in understanding sensitive settings? I turn to the Constructive Design Research framework and adapt it to classify how design fiction is used in HCI. I outline how design fiction can be used in the showroom approach, where it is most commonly placed, but also how it can be used as a lab and field approach to gather insights into the responses to design fictions. I developed design fictions and explored how they can be used to further discussions around the use of monitoring technologies in dementia care: an area challenging to research because of ethical issues associated with deployment studies of prototype technologies. The contribution of this thesis is threefold: first, a methodological contribution into the use of design fiction in HCI and an evaluation of the Constructive Design Research framework as a means to classify research through design fiction. Second, insights into participants’ views and wishes about technology-led care in regards to dementia. Third, a design contribution of artefacts that can be used to stimulate further debate around the topic
