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.

HERA-lding More Integration in Health? Examining the Discursive Legitimation of the European Commission's New Health Emergency Preparedness and Response Authority.

CONTEXT: Since COVID-19, the European Commission (EC) has sought to expand its activities in health through the development of a European Health Union and within it the Health Emergencies Preparedness and Response Authority (HERA). METHODS: The authors applied a discourse analysis to documents establishing HERA to investigate how the EC legitimated the creation of this institution. They focused on how it framed health emergencies, how it framed the added value of HERA, and how it linked HERA to existing EU activities and priorities. FINDINGS: Their analysis demonstrates that security-based logics have been central to the EC's legitimation of HERA in alignment with a "securitization of health" occurring worldwide in recent decades. This legitimation can be understood as part of the EC's effort to promote future integration in health in the absence of new competences. CONCLUSIONS: Securitization has helped the EC raise its profile in health politically without additional competences, thereby laying the groundwork for potential future integration. Looking at the discursive legitimation of HERA sheds light not only on whether the EC is expanding its health powers but also how it strategizes to do so. HERA, while constrained, allows the EC to further deepen security-driven integration in health.

Participatory policy analysis in health policy and systems research: reflections from a study in Nepal.

BACKGROUND: Participatory policy analysis (PPA) as a method in health policy and system research remains underexplored. Using our experiences of conducting PPA workshops in Nepal to explore the impact of the country's move to federalism on its health system, we reflect on the method's strengths and challenges. We provide an account of the study context, the design and implementation of the workshops, and our reflections on the approach's strengths and challenges. Findings on the impact of federalism on the health system are beyond the scope of this manuscript. MAIN BODY: We conducted PPA workshops with a wide range of health system stakeholders (political, administrative and service-level workforce) at the local and provincial levels in Nepal. The workshops consisted of three activities: river of life, brainstorming and prioritization, and problem-tree analysis. Our experiences show that PPA workshops can be a valuable approach to explore health policy and system issues - especially in a context of widespread systemic change which impacts all stakeholders within the health system. Effective engagement of stakeholders and activities that encourage both individual- and system-level reflections and discussions not only help in generating rich qualitative data, but can also address gaps in participants' understanding of practical, technical and political aspects of the health system, aid policy dissemination of research findings, and assist in identifying short- and long-term practice and policy issues that need to be addressed for better health system performance and outcomes. Conducting PPA workshops is, however, challenging for a number of reasons, including the influence of gatekeepers and power dynamics between stakeholders/participants. The role and skills of researchers/facilitators in navigating such challenges are vital for success. Although the long-term impact of such workshops needs further research, our study shows the usefulness of PPA workshops for researchers, for participants and for the wider health system. CONCLUSIONS: PPA workshops can effectively generate and synthesize health policy and system evidence through collaborative engagement of health system stakeholders with varied roles. When designed with careful consideration for context and stakeholders' needs, it has great potential as a method in health policy and systems research.

The impact of decentralisation on health systems: a systematic review of reviews.

BACKGROUND: Decentralisation is a common mechanism for health system reform; yet, evidence of how it impacts health systems remains fragmented. Despite published findings from primary and secondary research illustrating range of impacts, a comprehensive and clear understanding is currently lacking. This review synthesised the existing evidence to assess how decentralisation (by devolution) impacts each of the six WHO building blocks, and the health system. METHOD: We systematically searched five electronic databases for reviews exploring impact of decentralisation on health systems, globally. Reviews, both systematic and non-systematic, published in the English language from January 1990 to February 2022 were included. Data were synthesised across each of six building blocks. Quality assessment of the reviews was conducted using Critical Appraisal Skills Program for systematic and Scale for Assessment of Narrative Review Articles for non-systematic reviews. RESULTS: Nine reviews, each addressing somewhat different questions, contexts and issues, were included. A range of positive and negative impacts of decentralisation on health system building blocks were identified; yet, overall, the impacts were more negative. Although inconclusive, evidence suggested that the impacts on leadership and governance and financing components in particular shape the impact on overall health system. Assessment of how the impact on building blocks translates to the broader impact on health systems is challenged by the dynamic complexities related to contexts, process and the health system itself. CONCLUSIONS: Decentralisation, even if well intentioned, can have unintended consequences. Despite the difficulty of reaching universally applicable conclusions about the pros and cons of decentralisation, this review highlights some of the common potential issues to consider in advance.

Overcoming the challenges facing Nepal's health system during federalisation: an analysis of health system building blocks.

INTRODUCTION: Nepal's move to a federal system was a major constitutional and political change, with significant devolution of power and resources from the central government to seven newly created provinces and 753 local governments. Nepal's health system is in the process of adapting to federalism, which is a challenging, yet potentially rewarding, task. This research is a part of broader study that aims to explore the opportunities and challenges facing Nepal's health system as it adapts to federalisation. METHODS: This exploratory qualitative study was conducted across the three tiers of government (federal, provincial, and local) in Nepal. We employed two methods: key informant interviews and participatory policy analysis workshops, to offer an in-depth understanding of stakeholders' practical learnings, experiences, and opinions. Participants included policymakers, health service providers, local elected members, and other local stakeholders. All interviews were audio-recorded, transcribed, translated into English, and analysed thematically using the six WHO (World Health Organization) health system building blocks as a theoretical framework. RESULTS: Participants noted both opportunities and challenges around each building block. Identified opportunities were: (a) tailored local health policies and plans, (b) improved health governance at the municipality level, (c) improved health infrastructure and service capacity, (d) improved outreach services, (e) increased resources (health budgets, staffing, and supplies), and (f) improved real-time data reporting from health facilities. At the same time, several challenges were identified including: (a) poor coordination between the tiers of government, (b) delayed release of funds, (c) maldistribution of staff, (d) problems over procurement, and (e) limited monitoring and supervision of the quality of service delivery and data reporting. CONCLUSION: Our findings suggest that since federalisation, Nepal's health system performance is improving, although much remains to be accomplished. For Nepal to succeed in its federalisation process, understanding the challenges and opportunities is vital to improving each level of the health system in terms of (a) leadership and governance, (b) service delivery, (c) health financing, (d) health workforce, (e) access to essential medicines and technologies and (f) health information system.

Retinotopic connectivity maps of human visual cortex with unconstrained eye movements.

Human visual cortex contains topographic visual field maps whose organization can be revealed with retinotopic mapping. Unfortunately, constraints posed by standard mapping hinder its use in patients, atypical subject groups, and individuals at either end of the lifespan. This severely limits the conclusions we can draw about visual processing in such individuals. Here, we present a novel data-driven method to estimate connective fields, resulting in fine-grained maps of the functional connectivity between brain areas. We find that inhibitory connectivity fields accompany, and often surround facilitatory fields. The visual field extent of these inhibitory subfields falls off with cortical magnification. We further show that our method is robust to large eye movements and myopic defocus. Importantly, freed from the controlled stimulus conditions in standard mapping experiments, using entertaining stimuli and unconstrained eye movements our approach can generate retinotopic maps, including the periphery visual field hitherto only possible to map with special stimulus displays. Generally, our results show that the connective field method can gain knowledge about retinotopic architecture of visual cortex in patients and participants where this is at best difficult and confounded, if not impossible, with current methods.

Gender and caste inequalities in primary healthcare usage by under-5 children in rural Nepal: an iterative qualitative study into provider perspectives and the potential role of implicit bias.

OBJECTIVE: This study explored provider perspectives on: (1) why inequalities in health service usage persist; and (2) their knowledge and understanding of the role of patient experience and implicit bias (also referred to as unconscious bias). DESIGN: A three stage, iterative qualitative study was conducted involving two rounds of in-depth interviews and a training session with healthcare staff. Interview transcripts were analysed using a reflexive thematic approach in relation to the study's aims. SETTING: Participants were recruited from rural hill districts (Mugu, Humla, Bajura, Gorkha and Sindhupalchok) of Nepal. PARTICIPANTS: Clinical staff from 22 rural health posts. RESULTS: Healthcare providers had high levels of understanding of the cultural, educational and socioeconomic factors behind inequalities in healthcare usage in their communities. However, there was less knowledge and understanding of the role of patient experience-and no recognition at all of the concept of implicit bias. CONCLUSION: It is highly likely that implicit bias affects provider behaviours in Nepal, just as it does in other countries. However, there is currently not a culture of thinking about the patient experience and how that might impact on future usage of health services. Implicit bias training for health students and workers would help create greater awareness of unintended discriminatory behaviours. This in turn may play a part in improving patient experience and future healthcare usage, particularly among disadvantaged groups.

Access to assistive technology for persons with disabilities: a critical review from Nepal, India and Bangladesh.

PURPOSE: The purpose of this paper is to analyse and critically reflect on access to Assistive Technology (AT) for persons with disabilities (PWD) in Nepal, India and Bangladesh. This analysis aims to guide the development of a contextualised generic AT service delivery model suitable for these countries, based on the best practices identified. MATERIALS AND METHODS: This paper is based on a comprehensive study conducted in Nepal, India and Bangladesh, observing mobility and hearing-related AT service delivery centres run by the government, as well as private and nongovernmental organisations, and interviews with key informants: policymakers (5), AT service providers (20) and AT service users (20) between December 2019 to February 2020. A descriptive, qualitative exploratory study design was followed. A quality assessment framework was used to structure the analysis and interpret the findings. RESULTS: AT service provisions are poorly developed in all three countries. On all quality indicators assessed, the systems show major weaknesses. AT users have very limited awareness about their rights to these services and the availability of AT services, the range of services available is very limited, and eligibility is dependent on medical criteria related to visible and severe disabilities. CONCLUSIONS: Lack of accessibility, eligibility, reachability and affordability are the main barriers to access AT services for PWD in Nepal, India and Bangladesh. Increased community level awareness, increased Government funding and a community based, medically informed flexible social model of AT services is a way forward to ensure access to AT services for PWD in these countries.IMPLICATIONS FOR REHABILITATIONIncreased community awareness is necessary to increase access to Assistive Technology Services for Persons with Disabilities.Increased and flexible funding from the Government and philanthropists will improve rehabilitation.Establishment of community based Assistive Technology Services centres will increase access and improve rehabilitation.

Determinants affecting utilisation of health services and treatment for children under-5 in rural Nepali health centres: a cross-sectional study.

BACKGROUND: Large inequalities in child health remain in Nepal, with caste, ethnicity and sex being major determinants of deprivation and negative outcomes. The purpose of this study was to explore whether key demographics of under 5s were associated with health seeking behaviours, utilisation of health care, and treatment received. METHODS: Data came from Integrated Management of Neonatal & Childhood Illness (IMNCI) records of 23 health centres across five districts. After digitising the paper records, the data was analysed by district, caste/ethnicity, sex, and age to investigate differences in the time taken to present at a health facility after the onset of symptoms of ARI, diarrhoea and fever; accuracy of diagnosis for pneumonia; and whether the correct treatment was prescribed for pneumonia as per IMNCI guidelines. RESULTS: From 116 register books spanning 23 health centres, 30,730 child patient records were considered for analysis. The median age of attendance was 18 months (Inter-Quartile Range = 10, 32), while were more male children that attended (55.7% vs. 44.3% for females). There were statistically significant differences for the time taken to attend a health centre between different districts for ARI, diarrhoea and fever, with children in the remote Humla and Mugu districts taking significantly longer to present at a health facility after the onset of symptoms (all p < 0.001, except Mugu for ARI days). Children from underprivileged ethnic groups, Madhesi and Dalit, were less likely to be given a correct diagnosis of pneumonia (p = 0.014), while males were more likely to receive a correct diagnosis than females (73% vs. 67%, p = 0.001). This sex difference remained in the adjusted regression models for diagnosis of pneumonia (p < 0.001) but not for treatment of pneumonia (p = 0.628). All districts, in comparison to Gorkha, had increased odds of correct diagnosis and treatment of pneumonia, but only significant in children from Mugu after adjustment (p ≤ 0.001). CONCLUSION: Significant demographic differences were found based on ethnicity, sex, and district when examining health seeking behaviours for ARI, diarrhoea, and fever. Significant associations were seen for these same factors when exploring accuracy of diagnoses of pneumonia, but not for treatment. This study has emphasised the importance of a digitalised healthcare system, where inequalities can be identified without the reliance on anecdotal evidence.

Processes of assistive technology service delivery in Bangladesh, India and Nepal: a critical reflection.

PURPOSE: This paper critically reviews and reflects on the processes for providing Assistive Technology (AT) services to Persons with Disabilities (PWD) in Bangladesh, India and Nepal. The aim is to investigate the AT service delivery systems in these countries and suggest improvements where weaknesses are identified. MATERIALS AND METHODS: We carried out a descriptive qualitative exploratory study in Bangladesh, India and Nepal by conducting key informant interviews with policymakers (5), AT service providers (22) and mobility and hearing related AT service users (21). We used a directed content analysis approach guided by a seven-point AT service delivery process model to thematically analyse the existing processes for AT service delivery, from first contact through to follow-up and maintenance. RESULTS: AT service delivery processes are sub-optimal in all three countries, and improvements are needed. No common AT service delivery process was found, although there are common features. In general, it is easier for PWDs in India and Nepal to access AT than for those in Bangladesh, but all three countries are failing to live up to their commitments to uphold the human rights of PWDs. CONCLUSIONS: Although good elements of AT service delivery processes can be identified, the systems in all three countries are fragmented and generally weak. A more holistic approach of looking at the process of AT service delivery, from first contact right through to follow-up and device maintenance, with a single door service delivery system, free of cost at the point of service is recommended in these countries. IMPLICATIONS FOR REHABILITATIONAlthough we found significant weaknesses in AT delivery in all three countries, there are some good AT service delivery practices and opportunities for these countries to learn from one another.A systematic and stepwise approach to assessing current AT service delivery processes in the three countries - examining the delivery system as a whole, from initiation to repair and management - can help identify opportunities to improve the process for (prospective) AT users.A more coherent single door system of AT service delivery will increase the quality and efficiency of the fragmented AT service delivery practices in Bangladesh, India and Nepal.

Visual stress responses to static images are associated with symptoms of Persistent Postural Perceptual Dizziness (PPPD).

BACKGROUND: Images that deviate from natural scene statistics in terms of spatial frequency and orientation content can produce visual stress (also known as visual discomfort), especially for migraine sufferers. These images appear to over-activate the visual cortex. OBJECTIVE: To connect the literature on visual discomfort with a common chronic condition presenting in neuro-otology clinics known as persistent postural perceptual dizziness (PPPD). Patients experience dizziness when walking through highly cluttered environments or when watching moving stimuli. This is thought to arise from maladaptive interaction between vestibular and visual signals for balance. METHODS: We measured visual discomfort to stationary images in patients with PPPD (N = 30) and symptoms of PPPD in a large general population cohort (N = 1858) using the Visual Vertigo Analogue Scale (VVAS) and the Situational Characteristics Questionnaire (SCQ). RESULTS: We found that patients with PPPD, and individuals in the general population with more PPPD symptoms, report heightened visual discomfort to stationary images that deviate from natural spectra (patient comparison, F (1, 1865) = 29, p < 0.001; general population correlations, VVAS, rs (1387) = 0.46, p < 0.001; SCQ, rs (1387) = 0.39, p < 0.001). These findings were not explained by co-morbid migraine. Indeed, PPPD symptoms showed a significantly stronger relationship with visual discomfort than did migraine (VVAS, zH = 8.81, p < 0.001; SCQ, zH = 6.29, p < 0.001). CONCLUSIONS: We speculate that atypical visual processing -perhaps due to a visual cortex more prone to over-activation -may predispose individuals to PPPD, possibly helping to explain why some patients with vestibular conditions develop PPPD and some do not.

Re-examining critiques of resilience policy: evidence from Barpak after the 2015 earthquake in Nepal.

This paper examines three common critiques of 'resilience': (i) that it is a 'top-down' policy discourse that pays too little regard to local specificities; (ii) that resilience policy represents a neoliberal shift towards the responsibilisation of communities and a retreat of the state from its role in providing protection; and (iii) that the focus on resilience tends to divert attention from the underlying causes of vulnerability. Using data collected after the 2015 earthquake in Nepal, the paper argues that these critiques have mixed salience in this context, but that (i) and (iii) in particular point to important problems in how the central government and its international partners have approached enhancing the resilience of communities. While there are benefits to considering resilience at the local level, it is important to recognise the inequalities within communities, how these might be reflected in differential degrees of vulnerability, and how they might be reinforced through resilience-building programmes.

Further Evidence That People Rely on Egocentric Information to Guide a Cursor to a Visible Target.

Everyday movements are guided by objects' positions relative to other items in the scene (allocentric information) as well as by objects' positions relative to oneself (egocentric information). Allocentric information can guide movements to the remembered positions of hidden objects, but is it also used when the object remains visible? To stimulate the use of allocentric information, the position of the participant's finger controlled the velocity of a cursor that they used to intercept moving targets, so there was no one-to-one mapping between egocentric positions of the hand and cursor. We evaluated whether participants relied on allocentric information by shifting all task-relevant items simultaneously leaving their allocentric relationships unchanged. If participants rely on allocentric information they should not respond to this perturbation. However, they did. They responded in accordance with their responses to each item shifting independently, supporting the idea that fast guidance of ongoing movements primarily relies on egocentric information.

Detection of scene-relative object movement and optic flow parsing across the adult lifespan.

Moving around safely relies critically on our ability to detect object movement. This is made difficult because retinal motion can arise from object movement or our own movement. Here we investigate ability to detect scene-relative object movement using a neural mechanism called optic flow parsing. This mechanism acts to subtract retinal motion caused by self-movement. Because older observers exhibit marked changes in visual motion processing, we consider performance across a broad age range (N = 30, range: 20-76 years). In Experiment 1 we measured thresholds for reliably discriminating the scene-relative movement direction of a probe presented among three-dimensional objects moving onscreen to simulate observer movement. Performance in this task did not correlate with age, suggesting that ability to detect scene-relative object movement from retinal information is preserved in ageing. In Experiment 2 we investigated changes in the underlying optic flow parsing mechanism that supports this ability, using a well-established task that measures the magnitude of globally subtracted optic flow. We found strong evidence for a positive correlation between age and global flow subtraction. These data suggest that the ability to identify object movement during self-movement from visual information is preserved in ageing, but that there are changes in the flow parsing mechanism that underpins this ability. We suggest that these changes reflect compensatory processing required to counteract other impairments in the ageing visual system.

Choosing not to weaponize healthcare: politics and health service delivery during Nepal's civil war, 1996-2006.

Healthcare has often been 'weaponized' during armed conflicts, with parties to the conflict interfering with or violently attacking health facilities and personnel for their own strategic ends. In this exploratory study of the civil war in Nepal (1996-2006), by contrast, we look at a case in which both sides (with some exceptions) came to see it as in their interests to avoid targeting health facilities or deliberately disrupting healthcare delivery. Drawing on key informant interviews and documentary analysis, we identify four factors that appear to have contributed to the two sides making this choice: i) their interest in the continued functioning of the health systems (specifically, the need of the Maoists to access government-run facilities for treatment of their cadres, and the fact that Maoist healthcare provision ensured that at least some service delivery continued in areas under their control; ii) the fact that healthcare did not become an important 'ideological battleground' in the conflict; iii) the roles played by humanitarian and development organizations in shaping the behaviour of both the warring sides; and iv) the part played by health professionals in navigating the pressures on them and quickly mobilizing to resist more sustained attempts at interference with healthcare.

Persistent postural perceptual dizziness is on a spectrum in the general population.

OBJECTIVE: To examine the idea that symptoms of persistent postural perceptual dizziness (PPPD) are more common than previously assumed and lie on a spectrum in the general population, thus challenging current theories that PPPD is only a consequence of a vestibular insult. METHODS: We collected 2 common clinical questionnaires of PPPD (Visual Vertigo Analogue Scale [VVAS] and Situational Characteristics Questionnaire [SCQ]) in 4 cohorts: community research volunteers (n = 1941 for VVAS, n = 1,474 for SCQ); paid online participants (n = 190 for VVAS, n = 125 for SCQ); students (n = 204, VVAS only); and patients diagnosed with PPPD (n = 25). RESULTS: We found that around 9%, 4%, and 11%, respectively, of the 3 nonclinical cohorts scored above the 25th percentile patient score on 1 PPPD measure (VVAS) and 49% and 54% scored above the 25th percentile patient score on the other measure (SCQ). Scores correlated negatively with age (counter to expectation). As expected, scores correlated with migraine in 2 populations, but this only explained a small part of the variance, suggesting that migraine is not the major factor underlying the spectrum of PPPD symptoms in the general population. CONCLUSION: We found high levels of PPPD symptoms in nonclinical populations, suggesting that PPPD is a spectrum that preexists in the population, rather than only being a consequence of vestibular insult. Atypical visuo-vestibular processing predisposes some individuals to visually induced dizziness, which is then exacerbated should vestibular insult (or more generalized insult) occur.
