An open-ended primary-care group intervention for insomnia based on a self-help book - A randomized controlled trial and 4-year follow-up.

Chronic insomnia is a common and burdensome problem for patients seeking primary care. Cognitive behavioural therapy has been shown to be effective for insomnia, also when presented with co-morbidities, but access to sleep therapists is limited. Group-treatment and self-administered treatment via self-help books have both been shown to be efficacious treatment options, and the present study aimed to evaluate the effect of an open-ended group intervention based on a self-help book for insomnia, adapted to fit a primary-care setting. Forty primary-care patients with insomnia (mean age 55 years, 80% women) were randomized to the open-ended group intervention based on a cognitive behavioural therapy for insomnia self-help book or to a care as usual/wait-list control condition. Results show high attendance to group sessions and high treatment satisfaction. Participants in the control group later received the self-help book, but without the group intervention. The book-based group treatment resulted in significantly improved insomnia severity, as well as shorter sleep-onset latency, less wake time after sleep onset, and less use of sleep medication compared with treatment as usual. The improvements were sustained at a 4-year follow-up assessment. A secondary analysis found a significant advantage of the combination of the book and the open-ended group intervention compared with when the initial control group later used only the self-help book. An open-ended treatment group based on a self-help book for insomnia thus seems to be an effective and feasible intervention for chronic insomnia in primary-care settings.

Self-Selection of Bathroom-Assistive Technology: Development of an Electronic Decision Support System (Hygiene 2.0).

BACKGROUND: A clinical algorithm (Algo) in paper form is used in Quebec, Canada, to allow health care workers other than occupational therapists (OTs) to make bathroom adaptation recommendations for older adults. An integrated knowledge transfer process around Algo suggested an electronic version of this decision support system (electronic decision support system [e-DSS]) to be used by older adults and their caregivers in search of information and solutions for their autonomy and safety in the bathroom. OBJECTIVE: This study aims to (1) create an e-DSS for the self-selection of bathroom-assistive technology by community-dwelling older adults and their caregivers and (2) assess usability with lay users and experts to improve the design accordingly. METHODS: On the basis of a user-centered design approach, the process started with content identification for the prototype through 7 semistructured interviews with key informants of various backgrounds (health care providers, assistive technology providers, and community services) and 4 focus groups (2 with older adults and 2 with caregivers). A thematic content transcript analysis was carried out and used during the creation of the prototype. The prototype was refined iteratively using think-aloud and observation methods with a clinical expert (n=1), researchers (n=3), OTs (n=3), older adults (n=3), and caregivers (n=3), who provided information on the usability of the e-DSS. RESULTS: Overall, 4 themes served as the criteria for the prototype of the electronic Algo (Hygiene 2.0 [H2.0]): focus (safety, confidentiality, well-being, and autonomy), engage, facilitate (simplify, clarify, and illustrate), and access. For example, users first pay attention to the images (engage and illustrate) that can be used to depict safe postures (safety), illustrate questions embedded in the decision support tool (clarify and illustrate), and demonstrate the context of the use of assistive technology (safety and clarify). CONCLUSIONS: The user-centered design of H2.0 allowed the cocreation of an e-DSS in the form of a website, in line with the needs of community-dwelling older adults and their caregivers seeking bathroom-assistive technology that enables personal hygiene. Each iteration improved usability and brought more insight into the users' realities, tailoring the e-DSS to the implementation context.

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.

Perceived Barriers Before and After a 3-Month Period of Modified Ride-On Car Use.

PURPOSE: The purpose of the study is to examine how perceived barriers change before and after a 3-month period of modified ride-on car use. METHODS: This study used a qualitative content analysis of perceived barriers. Fourteen caregivers (13 mothers; 1 grandmother) responded to a single-question, free-response survey before and after a 3-month period of modified ride-on car use. RESULTS: A total of 11 and 20 perceived barriers were reported before and after the 3-month period. Environmental barriers were the most frequently reported before and after the 3-month period. CONCLUSIONS: Pediatric physical therapists need to be aware of the potential perceived barriers that families may experience in regard to young children with disabilities using modified ride-on cars and determine strategies to support families on an individual basis.

Experiences of computer-based and conventional self-help interventions for eating disorders: A systematic review and meta-synthesis of qualitative research.

OBJECTIVE: Self-help interventions have been demonstrated to be effective in treating bulimic-type eating disorders (EDs). In particular, computer-based interventions have received increasing attention due to their potential to reach a wider population. This systematic review aimed to synthesize findings from qualitative studies on users' experiences of self-help interventions for EDs and to develop an exploratory framework. METHOD: A systematic review and meta-synthesis on seven peer-reviewed qualitative studies on structured computer and book-based self-help interventions for EDs was conducted using Noblit and Hare's (1988) 7-phase meta-ethnography. Four of the selected studies investigated computer-based self-help programs, and three of the studies investigated book-based guided self-help programs. RESULTS: Six concepts were synthesized. They included intervention-related factors (anonymity and privacy; accessibility and flexibility; guidance) and user-related factors (agency/autonomy; self-motivation; and expectations/attitudes). The study revealed the "machine-like" and relational properties of the computer; the expansion of treatment time and space in psychological interventions, the changing role of the medical health professional from a "therapist" to a "guide," and a change from understanding interventions as a conclusive treatment plan to a starting point or stepping stone toward recovery. DISCUSSION: Computer-based self-help interventions should take advantage of the "machine-like" properties of a computer (neutrality, availability, etc.) as well as its ability to facilitate human interactions. Users should also be facilitated to have a realistic understanding of the purpose of self-help interventions and the place of self-help interventions in their broader treatment plans to moderate expectations and attitudes.

OBJETIVO: Las intervenciones de auto-ayuda han demostrado ser efectivas para tratar trastornos de la conducta alimentaria (TCA) tipo bulímico. En particular, las intervenciones basadas en computadora han recibido una creciente atención debido al potencial de poder alcanzar una población más amplia. Esta revisión sistemática tuvo como objetivo el sintetizar los hallazgos de los estudios cualitativos de las experiencias de usuarios de intervenciones de auto-ayuda para TCAs y para desarrollar un marco exploratorio. MÉTODO: Se realize una revisión sistemática y meta-síntesis de siete artículos de estudios cualitativos revisados por pares sobre intervenciones estructuradas de auto-ayuda basadas en libro y en computadora para los TCAs utilizando la meta-etnografía de 7 fases de Noblit y Hare (1988). Cuatro de los estudios seleccionados investigaron programas de autoayuda basados en computadora, y tres de los estudios investigaron programas de autoayuda guiados basados en libros. RESULTADOS: Se sintetizaron seis conceptos. Incluían factores relacionados con la intervención (anonimato y privacidad; accesibilidad y flexibilidad; orientación) y factores relacionados con el usuario (agencia/autonomía; auto-motivación; y expectativas/actitudes). El estudio reveló que la computadora poseía propiedades "similares a una máquina" y propiedades relacionales; la expansión del tiempo y el espacio de tratamiento en las intervenciones psicológicas, el rol cambiante del profesional médico de un "terapeuta" a un "guía", y un cambio de la comprensión de las intervenciones como un plan de tratamiento concluyente a un punto de partida o paso hacia la recuperación. DISCUSIÓN: Las intervenciones de autoayuda basadas en computadora deben aprovechar las propiedades "similares a una máquina" de una computadora (neutralidad, disponibilidad, etc.) así como su capacidad para facilitar las interacciones humanas. Los usuarios también deben ser facilitados para tener una comprensión realista del propósito de las intervenciones de autoayuda y el lugar de las intervenciones de autoayuda en sus planes de tratamiento más amplios para moderar las expectativas y las actitudes.

Informal carers' experience of assistive technology use in dementia care at home: a systematic review.

BACKGROUND: Dementia is a health and care priority globally. Caring for persons with dementia is a challenge and can lead to negative psychological, physiological and financial consequences for informal carers. Advances in technology have the potential to assist persons with dementia and their carers, through assistive technology devices such as electronic medication dispensers, robotic devices trackers and motion detectors. However, little is known about carers' experience and the impact of these technologies on them. This review aims to investigate the outcomes and experience of carers of persons with dementia, who live at home and use assistive technology. METHODS: A systematic search in seven databases and manual searches were carried out using pre-defined inclusion and exclusion criteria to identify studies on carers of persons with dementia involving the use of assistive technology. The search identified 56 publications with quantitative, qualitative and mixed-method designs. RESULTS: The studies reported positive and negative findings and focused on a wide variety of assistive technology devices. There were large differences in the uses of assistive technology, outcome measures used and the quality of studies. Knowledge and acceptance, competence to use and ethical issues when using assistive technology were themes that emerged from the studies. Carers generally appreciated using assistive technology and their experience of use varied. CONCLUSIONS: The intention of this systematic review is to list and classify the various types of assistive technology used by carers of persons with dementia and explores the positive and negative aspects, knowledge, acceptance and ethical issues in the use of assistive technology by carers of persons with dementia. We recommend the use of a standard and person-centred system of classifying and naming assistive technology devices and systems and for future research efforts in assistive technology to incorporate a family/carer centred model.

Use of Assistive Devices to Lift, Transfer, and Reposition Hospital Patients.

BACKGROUND: Devices to lift, transfer, and reposition patients are recommended for healthcare workers' and patients' safety, but their intended use has yet to be fully realized. OBJECTIVE: The aim of this study was to describe hospital nursing staff use of lift/transfer devices and the presence of factors at the time of lifts/transfers with potential to influence whether devices are used. METHODS: Participants were 108 US nursing staff in a university-based medical center and two community hospitals. A self-completed questionnaire was used to collect demographic and work characteristics, typical frequency of patient lifts/transfers, training in and typical use of lift equipment, and specific factors that could influence use. Proportional distributions of lifting/transferring and repositioning frequencies in a typical shift, amount of equipment use, and factors present were examined overall and across worker and work-related characteristics. RESULTS: Although trained in equipment use, only 40% used equipment for at least half of lifts/transfers. During lifts/transfers, factors often present included patient unable to help with lift/transfer (91.3%) or of a size/weight where participant needed assistance to help lift/transfer (87.5%); availability of others who could assist with manual lift (86.3%) or use of lift equipment (82.4%); and equipment functioning properly (86.4%), having supplies available (82.5%), and being easy to retrieve from storage (81.6%). During repositioning tasks, physical assistance was "always/almost always" provided from coworkers (83.3%) and often perceived as "very helpful" (92.6%) in reducing physical demands. Physical assistance from patients was less common (14.0% "always/almost always") yet perceived as "very helpful" by 66.3%. One fifth always used friction-reducing devices. DISCUSSION: Despite training in their use, nursing staff use of available lift equipment and assistive devices is limited. Factors present at the time of lifts/transfers that may influence equipment/device use reflect a complex mix of patient, worker, equipment, and situational characteristics.

Linking the Psychosocial Impact of Assistive Devices Scale (PIADS) to the International Classification of Functioning, Disability, and Health.

PURPOSE: Assistive technologies are widely implemented in clinical and research settings. Despite their dissemination, the psychosocial impact of their adoption still deserves further consideration. The aim of the present study is to determine the degree of compatibility between the Psychosocial Impact of Assistive Devices Scale (PIADS) and the International Classification of Functioning, Disability, and Health (ICF). METHODS: Six health professionals (two neurologists, one neuro-rehabilitation technician, two psychologists, one university professor of rehabilitation) created a technical board to discuss upon the PIADS-ICF linking. The standardized linking methodology was applied, and a Delphi technique was used to examine consensus. RESULTS: Five Delphi sessions were required to reach 100% of consensus and to finalize the procedure. Of the 26 PIADS' items, 23 were linked to an ICF category: 9 items were endorsed at the 3rd ICF level, and 14 items at the 2nd ICF level. Two items were classified as "not defined" and 1 item as "not covered". CONCLUSION: The study highlighted the conceptual connection between the PIADS and the ICF framework and set a bio-psychosocial standpoint by which accounting the role of assistive devices in rehabilitation settings.

A Global Public Health Perspective: Facilitating Access to Assistive Technology.

SIGNIFICANCE: Clinicians should not overlook vulnerable populations with limited access to assistive technology (AT), the importance of collaboration in multidisciplinary teams, advocacy for enabling environments, and supportive health systems. Resources, a model of care, and recommendations can assist clinicians in contributing to changing attitudes, expanding knowledge, and improving the lives of many.The increasing availability of innovative advances in AT can immeasurably enhance the quality of life of people with disabilities. Clinicians will undoubtedly welcome the prospect of having cutting-edge AT available to prescribe to individuals who consult them. Arguably, though, the development of innovative strategies to improve access to AT, especially to underserved people "left behind," is equally urgent. Current efforts are inadequate, with millions of people with disabilities not being reached. Particularly at risk are women, children, and the elderly, as well as poorer people who live in resource-poor and remote areas, especially in low- and middle-income countries. Not only must physical access be facilitated, but also quality services must be available. Good-quality, affordable AT, which is appropriate and acceptable to the user, would ideally be provided by competent personnel, working in multidisciplinary teams, offering comprehensive, person-centered services, including rehabilitation, fully integrated into the various levels of the health system. Clinicians can contribute to improving access to quality services, participate in initiatives aiming to increase the knowledge of health personnel and the public, engage in advocacy to change attitudes, influence legislation, and raise awareness of universal health coverage-ultimately facilitating access to AT for all.

The use of assistive technology in shoulder exercise rehabilitation - a qualitative study of acceptability within a pilot project.

BACKGROUND: Painful shoulders pose a substantial socioeconomic burden accounting for 2.4% of all primary care consultations in the UK. There is a strong evidence to indicate that the majority of this shoulder pain can be managed successfully with exercise based treatments and that common surgical procedures provide no extra benefit. Patient adherence and engagement is cited as an important factor in gaining positive outcomes. The MUJO System has been designed to help target the rehabilitation of the rotator cuff muscles which are commonly recommended for the management of shoulder pain. The purpose of this qualitative study was to evaluate the acceptability of the MUJO System amongst clinicians and patients. METHODS: A qualitative study was undertaken to look at the usability of the MUJO System both from clinicians' and patients' perspectives. Patients with shoulder problems were identified by an experienced physiotherapist using the study eligibility criteria. and invited to participate. Semi-structured interviews were performed with patients and clinicians to explore factors surrounding its acceptability and feasibility of use. The study was designed using Normalisation Process Theory as a theoretical basis for the inquiry. RESULTS: Seven physiotherapists and ten patients were interviewed in the study. The Internal and External Devices were seen as having the potential to rehabilitate the rotator cuff however it posed limitations towards more functional based exercises. Patients and clinicians found the visual feedback from the Patient App enhanced the rehabilitation experience. The Internal and External Devices were acceptable to all for rehabilitation providing the devices were available for use by the patients in the community. CONCLUSION: Patients and clinicians found the MUJO System acceptable as a modality to perform shoulder exercises. For the MUJO System to be taken up as a routine part of clinical practice patients need to be able to access the devices in the community. For the MUJO System to be taken up in clinical practice it needs to be workable within the context of the treatment pathway and not interfere with standard processes.

Robotic Services Acceptance in Smart Environments With Older Adults: User Satisfaction and Acceptability Study.

BACKGROUND: In Europe, the population of older people is increasing rapidly. Many older people prefer to remain in their homes but living alone could be a risk for their safety. In this context, robotics and other emerging technologies are increasingly proposed as potential solutions to this societal concern. However, one-third of all assistive technologies are abandoned within one year of use because the end users do not accept them. OBJECTIVE: The aim of this study is to investigate the acceptance of the Robot-Era system, which provides robotic services to permit older people to remain in their homes. METHODS: Six robotic services were tested by 35 older users. The experiments were conducted in three different environments: private home, condominium, and outdoor sites. The appearance questionnaire was developed to collect the users' first impressions about the Robot-Era system, whereas the acceptance was evaluated through a questionnaire developed ad hoc for Robot-Era. RESULTS: A total of 45 older users were recruited. The people were grouped in two samples of 35 participants, according to their availability. Participants had a positive impression of Robot-Era robots, as reflected by the mean score of 73.04 (SD 11.80) for DORO's (domestic robot) appearance, 76.85 (SD 12.01) for CORO (condominium robot), and 75.93 (SD 11.67) for ORO (outdoor robot). Men gave ORO's appearance an overall score higher than women (P=.02). Moreover, participants younger than 75 years understood more readily the functionalities of Robot-Era robots compared to older people (P=.007 for DORO, P=.001 for CORO, and P=.046 for ORO). For the ad hoc questionnaire, the mean overall score was higher than 80 out of 100 points for all Robot-Era services. Older persons with a high educational level gave Robot-Era services a higher score than those with a low level of education (shopping: P=.04; garbage: P=.047; reminding: P=.04; indoor walking support: P=.006; outdoor walking support: P=.03). A higher score was given by male older adults for shopping (P=.02), indoor walking support (P=.02), and outdoor walking support (P=.03). CONCLUSIONS: Based on the feedback given by the end users, the Robot-Era system has the potential to be developed as a socially acceptable and believable provider of robotic services to facilitate older people to live independently in their homes.

Preliminary development of an advanced modular pressure relief cushion: Testing and user evaluation.

STUDY AIM: Effective pressure relief cushions are identified as a core assistive technology need by the World Health Organization Global Cooperation on Assistive Technology. High quality affordable wheelchair cushions could provide effective pressure relief for many individuals with limited access to advanced assistive technology. MATERIALS: Value driven engineering (VdE) principles were employed to develop a prototype modular cushion. Low cost dynamically responsive gel balls were arranged in a close packed array and seated in bilayer foam for containment and support. Two modular cushions, one with high compliance balls and one with moderate compliance balls were compared with High Profile and Low Profile Roho® and Jay® Medical 2 cushions. METHODS: ISO 16480-2 biomechanical standardized tests were applied to assess cushion performance. A preliminary materials cost analysis was carried out. A prototype modular cushion was evaluated by 12 participants who reported satisfaction using a questionnaire based on the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) instrument. RESULTS: Overall the modular cushions performed better than, or on par with, the most widely prescribed commercially available cushions under ISO 16480-2 testing. Users rated the modular cushion highly for overall appearance, size and dimensions, comfort, safety, stability, ease of adjustment and general ease of use. Cost-analysis indicated that every modular cushion component a could be replaced several times and still maintain cost-efficacy over the complete cushion lifecycle. CONCLUSION: A VdE modular cushion has the potential provide effective pressure relief for many users at a low lifetime cost.

Algo Used by Homecare Nonoccupational Therapists Selecting Bathing Assistive Technology: Enhancing Standardization by Exploring Clinical Reasoning.

Algo is a clinical decision algorithm developed to support nonoccupational therapists in establishing assistive technology recommendations to enable physically disabled adults to perform their hygiene at home. This study aimed to explore the in-depth clinical reasoning of nonoccupational therapists using Algo to pinpoint the items leading to disagreements regarding recommendations. A multiple-case study was conducted with eight nonoccupational therapists trained to use Algo and filmed while using it with six standardized clients. Explicitation interviews were conducted for the conflicting recommendations. Identifying the key reasoning skills to develop in Algo users has led to three recommendations to enhance standardization with seniors.

Lessons learned from studying the functional impact of adaptive seating interventions for children with cerebral palsy.

Little empirical evidence exists about the effectiveness of assistive technology interventions for children with cerebral palsy (CP) to inform clinical practice. This article reviews what we know about the functional impact of adaptive seating interventions - a common assistive technology type recommended for children with CP. A contemporary assistive technology outcomes framework is considered as a way to model the temporality and measure the effects of seating interventions and moderating cofactors. Three research studies are profiled to illustrate different research methods, measurement approaches, and follow-up periods to learn about adaptive seating outcomes. Recommendations for future research include the adoption of common measurement indicators, consideration of quality assessment criteria, and the use of varied methodologies to generate new knowledge about functional outcomes. It is suggested that the proposed strategies will lead to new understandings, clinical applications, and ultimately improvements in the everyday lives of children with CP and their families.

Assistive products and the Sustainable Development Goals (SDGs).

The Sustainable Development Goals (SDGs) have placed great emphasis on the need for much greater social inclusion, and on making deliberate efforts to reach marginalized groups. People with disabilities are often marginalized through their lack of access to a range of services and opportunities. Assistive products can help people overcome impairments and barriers enabling them to be active, participating and productive members of society. Assistive products are vital for people with disabilities, frailty and chronic illnesses; and for those with mental health problems, and gradual cognitive and physical decline characteristic of aging populations. This paper illustrates how the achievement of each of the 17 SDGs can be facilitated by the use of assistive products. Without promoting the availability of assistive products the SDGs cannot be achieved equitably. We highlight how assistive products can be considered as both a mediator and a moderator of SDG achievement. We also briefly describe how the Global Cooperation on Assistive Technology (GATE) is working to promote greater access to assistive products on a global scale.

Problems of older persons using a wheeled walker.

BACKGROUND: Wheeled walkers (WWs) are used to improve mobility and for fall prevention in older persons, but not all users are satisfied with the usability of WWs. Intelligent WWs are being developed to improve the usability. AIMS: The aim of this study was to support the development of intelligent WWs by investigating possible problems of using a WW. METHODS: This study investigated 22 geriatric in-patients (median age 82 years) with and without their WW while opening a door against the direction of walking and passing through. Other possible problems when using WWs were identified by interview. RESULTS: Walking through the door was faster without than with using the WW (8.71 versus 12.86 s, p < 0.001), while interference between door and WW was documented in 41 of 44 (93 %) cases. Backward walking performance was better when using a WW with regard to gait speed, step width and walk ratio (all p < 0.002). Most referred problems when using a WW were walking downhill (83 %) and uphill (77 %) and obstacle crossing in general (77 %). CONCLUSIONS: Problems with opening a door against the direction of walking and the optimization of downhill and uphill walking as well as obstacle crossing should be regarded when developing an intelligent WW.

Rehabilitation Engineering & Assistive Technology Society (RESNA) position on the application of wheelchair standing devices: 2013 current state of the literature.

This article, approved by the Rehabilitation Engineering & Assistive Technology Society of North America Board of Directors on December 23, 2013, shares typical clinical applications and provides evidence from the literature supporting the use of wheelchair standers.

Contributions of ambient assisted living for health and quality of life in the elderly and care services--a qualitative analysis from the experts' perspective of care service professionals.

BACKGROUND: Because of the demographic change in industrial countries new technical solutions for the independent living of elderly will become important in the next years. Ambient Assisted Living seeks to address the upcoming challenges by providing technical aids for elderly and care givers. Therefore it is crucial to understand how those socio-technical solutions can address their needs and quality of life (QOL). The aim of this study was to analyse the main needs of dependent elderly and to investigate how different solutions can contribute to health and quality of life. METHODS: A qualitative study design consisting of interviews with 11 professionals of geriatric care organisations was chosen. The data analysis was done by applying the qualitative content analysis by Philipp Mayring. The analysis was based on the basic principle of the bio-psycho-social model of health RESULTS: Ambient Assisted Living solutions and assistive technologies can have positive impacts on different dimensions of health and quality of life. The needs and problems of elderly can be addressed by applying appropriate solutions which influence the physical, mental and social dimensions of quality of life. There are also benefits for social care providers, their staff and caring relatives of impaired elderly. Ambient Assisted Living solutions can also be used as a facilitator for operational optimization of care services. CONCLUSIONS: Solutions for telemedicine and telecare which are connected to Ambient Assisted Living solutions will have the biggest positive impact on care giving services. Also simple technical aids can be beneficial for elderly to enhance QOL by enabling autonomy in their familiar surroundings.

Can home health aids using the clinical algorithm Algo choose the right bath seat for clients having a straightforward problem?

OBJECTIVE: To determine if Algo, a clinical algorithm to select bathing equipment for 'straightforward' cases, guides home health aides in selecting the appropriate bath seat. DESIGN: Criterion validity study. SETTING: Community home care. SUBJECTS: Eight home health aides used Algo with community-dwelling older adults having a straightforward problem. MAIN MEASURES: Their bath-seat recommendations were compared with those proposed by an occupational therapist (OT), which were considered as the gold standard. In order to determine a clinically acceptable threshold of agreement between the recommendations, a subgroup of community-dwelling elderly people was assessed a third time by another OT. RESULTS: Half of the clients (74/143) for whom bathroom assessments were requested qualified as potentially straightforward cases after triage and were visited at home by a home health aide using Algo. In 84% of cases (95% confidence interval (CI) = [75, 93]), the non-OTs using Algo identified a seat that would enable these older adults to bathe according to their preferences, abilities and environment, as confirmed by the gold standard OT. Moreover, this appropriateness rate did not statistically differ from that obtained when comparing another OT to the gold standard. CONCLUSION: Algo guides non-OTs toward a bath seat that meets the needs of community-dwelling older adults in the majority of cases.
