Estimating need and coverage for five priority assistive products: a systematic review of global population-based research

Theories, models and frameworks to understand barriers to the provision of mobility-assistive technologies: a scoping review

OBJECTIVES

There is strong evidence that mobility-assistive technologies improve occupational performance, social participation, educational and employment access and overall quality of life in people with disabilities. However, people with disabilities still face barriers in accessing mobility products and related services. This review aims to summarise and synthesise: (1) theories, models and frameworks that have been used to understand mobility-assistive technology access, (2) determinants of access and (3) gaps in knowledge.

DESIGN

A scoping review using the five-step framework by Arksey and O'Malley.

DATA SOURCES

We searched the MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature and SCOPUS databases for publications published between 2000 and 2024. We searched for articles published up to 20 March 2024.

ELIGIBILITY CRITERIA

We included English-published literature in peer-reviewed journals that reported (a) barriers to the provision of mobility-assistive technologies, (b) including at least one theory, model or framework and (c) between 2000 and 2024.

DATA EXTRACTION AND SYNTHESIS

We extracted the study characteristics, theories, models, framework usage, research recommendations, key findings on mobility-assistive technology barriers and theoretical propositions. We conduct a theoretical synthesis guided by Turner's approach.

RESULTS

We included 18 articles that used 8 theories, models and frameworks, synthesised into 9 propositions. The synthesised theory emphasises that mobility is essential for human flourishing, and that certain health conditions may impose restrictions on mobility. This impact can be alleviated by two direct determinants: (1) the provision of suitable services and (2) their comprehensive provision. Policies and costs influence these services indirectly. Environmental and personal factors also affect the use of these services. Ineffectively addressing these determinants can limit access to mobility-assistive technologies and subsequent disabilities.

CONCLUSION

Our synthetic model describes the logic of providing evidence-based mobility-assistive technologies, and we identify the determinants of access that can act as targets for future work to improve the provision of mobility-assistive technologies.

Development of the national priority assistive product list in Malawi

PURPOSE

In 2016 WHO launched the priority assistive products list (APL) consisting of 50 products and recommended that using this as a reference, countries should develop their own contextually relevant national APLs. This paper describes the development of Malawi's APL.

METHODS

Two hundred and ninety-six persons with disabilities participated in a rapid Assistive Technology Assessment (rATA) survey. Six focus group discussions (FGDs) with people with various types of disabilities were conducted. The rATA questionnaire and FGDs collected data on assistive products (APs) participants used, APs they needed and the challenges they experienced. Data collection was done in six districts spread across the three regions in Malawi. All age groups were included in the survey. Persons with disabilities aged less than 18 participated but went with their guardians. All persons who participated in this study provided consent. Survey and FGDs results were presented at an APL consensus meeting with policymakers, service providers, disabled peoples' organizations and development partners in the disability sector. Based on the results and further discussions, a consensus was reached on the priority APs for Malawi.

RESULTS

More than a third of respondents used wheelchairs (32%), followed by auxiliary crutches (25%), walking sticks (13%), reading glasses (11%), prosthesis (10%), elbow crutches (9%) and orthosis (8%). There is also a high demand for products such as pull-up underwear (incontinence products) (79%), hearing aids (70%), reading glasses (59%) and diapers (63%). After intensive discussions during a consensus meeting, an agreement was reached on the 22 priority APs for Malawi.

CONCLUSION

There is a wide range of APs being used by people with different functional limitations in Malawi. There is also a demand for APs that are not readily available. When developing an APL, the list should include products in use, those in demand, and those recommended by service providers.

Assistive technology in Korea: Findings from the 2017 National Disability Survey

PURPOSE

Explicitly monitoring the need, use and satisfaction of assistive product (AP) provision is essential to support population health and healthy longevity in ageing/aged countries, like Korea. We present findings from the 2017 Korea National Disability Survey (NDS) on AP access and compare them to international averages, introducing Korea's data into the wider coherence of global AP research.

MATERIALS AND METHODS

Using data from Korea's 2017 NDS, surveying 91,405 individuals, we extracted and calculated AP access indicators, including needing, having, using and being satisfied with 76 unique APs, by functional difficulty and product type. We compared satisfaction and unmet need between the National Health Insurance System (NHIS) and alternative provision services.

RESULTS

Prosthetics and orthotics had high rates of under-met need, and lower satisfaction rates, from 46.9% to 80.9%. Mobility APs overall had higher rates of under-met need. There was either low (<5%) or no reported need for most digital/technical APs. Among main products, those provided through the NHIS had lower unmet need (26.4%) than through alternative providers (63.1%), though satisfaction rates were similar (p < .001).

CONCLUSIONS

The Korean survey findings align with global averages calculated in the Global Report on Assistive Technology. Low reported needs for certain APs may reflect low awareness about how these products could benefit users, emphasizing the importance of data collection at each stage of the AP provision process. Recommendations to expand access to APs are given for people, personnel, provision, products, and policy.

Low adoption of mobility device in later life: Insights from the lens of intersectionality

OBJECTIVES

To investigate the utilization of mobility device, whether age and gender-related use disparities exist, and whether falls can further explain use disparities over time among Chinese older adults in need of devices.

METHODS

Community-dwelling older adults who needed mobility devices and completed four waves of the China Health and Retirement Survey 2011-2018 were included (N = 1,302). A categorical variable was created to represent respondents' intersectionality of age (50-64, 65-74, and ≥75 years) and gender (men vs. women).

RESULTS

The baseline prevalence of device use was 18.2 % (n = 237). Overall, the device use increased over time. Intersectionality-wise, oldest-old women were 1.53 times more likely than youngest-old men to use devices over time. Respondents with falls were more likely to use devices over time.

CONCLUSIONS

Older adults with mobility impairment, especially the oldest-old women and those with falls, lag in mobility devices utilization, suggesting future tailored interventions to support these populations.

Assistive technology needs, access and coverage, and related barriers and facilitators in the WHO European region: a scoping review

PURPOSE

Globally, assistive technology (AT) is used by over 1 billion people, but the prevalence of needs and access to AT in specific countries or regions is largely unknown. This scoping review summarises the evidence available on the prevalence of needs, access and coverage of AT in the World Health Organisation European Region and the barriers and facilitators to its use.

METHODS

Relevant publications were identified using a combination of two strategies: 1) a systematic search for AT publications in five scientific literature databases; and 2) consultations with 76 of the Region's AT experts.

RESULT

The search strategies yielded 103 publications, 62 of them identified by the systematic search. The included publications were predominantly from six countries, and 18 countries were unrepresented. Information on AT use for specific functional impairments was present in 57 publications: AT for hearing impairment in 14 publications; vision in 12; mobility, 12; communication, 11; self-care, 6; and cognition, 2. AT needs for vision and hearing impairment were more likely to be met (1-87% and 5-90%, respectively) compared with communication and cognition impairments (10-60% and 58%, respectively). The barriers and facilitators to AT access described were linked to accessibility, affordability and acceptability.

CONCLUSION

Data on AT prevalence and coverage are limited in both quantity and quality. Agreed-upon definitions of functional impairment and assistive product categories and standards for data collection are needed to facilitate data comparisons and to build a more representative picture of AT needs and coverage.Implications for rehabilitationComprehensive and disaggregated data concerning the prevalence of needs and coverage of AT is needed to enable the development of responsive policies and actions.The literature available on the prevalence of needs and coverage of AT in the WHO European Region is primarily focussed on a small subset of countries and comparisons between studies are limited due to the use of different data collection strategies.Evidence concerning barriers and facilitators to AT access across countries is more consistent and can be organised across the key themes of accessibility, affordability and acceptability of AT.There is a need for consensus among multiple AT actors on standardised definitions for functional impairment and assistive product categories and standards for data collection to enable a more representative picture to be built of AT needs and coverage across the WHO European Region and globally.

The acceptance and attitudes towards using assistive technology for people with stroke in Jordan: caregivers' perspectives

The aim of this study is to evaluate the acceptance and attitudes toward assistive technology (AT) for people with stroke from their caregivers' perspectives in Jordan. Also, this study further validates the Unified Theory of Acceptance and Use of Technology (UTAUT) questionnaire. This is a cross-sectional study that includes a three-sections survey: the first section contains demographic data, the second section includes the Unified Theory of Acceptance and Use of Technology (UTAUT) questionnaire, and the third section consists of two optional open-ended questions. Among 123 caregivers of people with stroke over 18 years of age who participated in this study, 23% were male. The findings indicate a moderate to high acceptance of using AT for stroke survivors, confirm the validity and reliability of the UTAUT questionnaire, and clarify novel issues regarding AT based on the caregivers' perspectives.

Design and Evaluation of the Extended FBS Model Based Gaze-Control Power Wheelchair for Individuals Facing Manual Control Challenges

This study addresses the challenges faced by individuals with upper limb disadvantages in operating power wheelchair joysticks by utilizing the extended Function-Behavior-Structure (FBS) model to identify design requirements for an alternative wheelchair control system. A gaze-controlled wheelchair system is proposed based on design requirements from the extended FBS model and prioritized using the MosCow method. This innovative system relies on the user's natural gaze and comprises three levels: perception, decision making, and execution. The perception layer senses and acquires information from the environment, including user eye movements and driving context. The decision-making layer processes this information to determine the user's intended direction, while the execution layer controls the wheelchair's movement accordingly. The system's effectiveness was validated through indoor field testing, with an average driving drift of less than 20 cm for participates. Additionally, the user experience scale revealed overall positive user experiences and perceptions of the system's usability, ease of use, and satisfaction.

Assistive technology access in longitudinal datasets: a global review

Functional limitations become more prevalent as populations age, emphasising an increasingly urgent need for assistive technology (AT). Critical to meeting this need trajectory is understanding AT access in older ages. Yet few publications examine this from a longitudinal perspective. This review aims to identify and collate what data exist globally, seeking all population-based cohorts and repeated cross-sectional surveys through the Maelstrom Research Catalogue (searched May 10, 2022) and the Disability Data Report (published 2022), respectively. Datasets incorporating functional limitations modules and question(s) dedicated to AT, with a wave of data collection since 2009, were included. Of 81 cohorts and 202 surveys identified, 47 and 62 meet inclusion criteria, respectively. Over 40% of cohorts were drawn from high-income countries which have already experienced significant population ageing. Cohorts often exclude participants based on pre-existing support needs. For surveys, Africa is the most represented region (40%). Globally, 73% of waves were conducted since 2016. 'Use' is the most collected AT access indicator (69% of cohorts and 85% of surveys). Glasses (78%) and hearing aids (77%) are the most represented AT. While gaps in data coverage and representation are significant, collating existing datasets highlights current opportunities for analyses and methods for improving data collection across the sector.

Disability and the achievement of Universal Health Coverage in the Maldives

OBJECTIVE

To assess access to general and disability-related health care among people with disabilities in the Maldives.

METHODS

This study uses data from a case-control study (n = 711) nested within a population-based, nationally representative survey to compare health status and access to general healthcare amongst people with and without disabilities. Cases and controls were matched by gender, location and age. Unmet need for disability-related healthcare is also assessed. Multivariate regression was used for comparisons between people with and without disabilities.

RESULTS

People with disabilities had poorer levels of health compared to people without disabilities, including poorer self-rated health, increased likelihood of having a chronic condition and of having had a serious health event in the previous 12 months. Although most people with and without disabilities sought care when needed, people with disabilities were much more likely to report difficulties when routinely accessing healthcare services compared to people without disabilities. Additionally, 24% of people with disabilities reported an unmet need for disability-related healthcare, which was highest amongst people with hearing, communication and cognitive difficulties, as well as amongst older adults and people living in the lowest income per capita quartile. Median healthcare spending in the past month was modest for people with and without disabilities. However, people with disabilities appear to have high episodic healthcare costs, such as for disability-related healthcare and when experiencing a serious health event.

CONCLUSIONS

This study found evidence that people with disabilities experience unmet needs for both disability-related and general healthcare. There is therefore evidence that people with disabilities in the Maldives are falling behind in core components relevant to UHC: availability of all services needed, and quality and affordability of healthcare.

Exploring the Use of Washington Group Questions to Identify People with Clinical Impairments Who Need Services including Assistive Products: Results from Five Population-Based Surveys

This study analyses the use of the self-reported Washington Group (WG) question sets as a first stage screening to identify people with clinical impairments, service and assistive product (AP) referral needs using different cut-off levels in four functional domains (vision, hearing, mobility and cognition). Secondary data analysis was undertaken using population-based survey data from five countries, including one national survey (The Gambia) and four regional/district surveys (Cameroon, Chile, India and Turkey). In total 19,951 participants were sampled (range 538–9188 in individual studies). The WG question sets on functioning were completed for all participants alongside clinical impairment assessments/questionnaires. Using the WG “some/worse difficulty” cut-off identified people with mild/worse impairments with variable sensitivity (44–79%) and specificity (73–92%) in three of the domains. At least 64% and 60% of people with mild/worse impairments who required referral for surgical/medical and rehabilitation/AP services, respectively, self-reported “some/worse difficulty”, and much fewer reported “a lot/worse difficulty.” For moderate/worse impairment, both screening cut-offs improved identification of service/AP need, but a smaller proportion of people with need were identified. In conclusion, WG questions could be used as a first-stage screening option to identify people with impairment and referral needs, but only with moderate sensitivity and specificity.
