Estimates of the birth prevalence of clubfoot in low and middle income settings range from 0.5 to 2 per 1000 births. However, there is currently no estimate of global birth prevalence of clubfoot.

A systematic review of studies was carried out reporting the birth prevalence of clubfoot across all countries and regions worldwide in the last 10 years. Africa Wide Information, EMBASE, CINAHL, Global Health, LILACS and Medline databases were searched for relevant studies from January 1st 2012 to February 9th 2023. Pooled prevalence estimates were calculated using the inverse variance method, and a random effects model was applied to account for heterogeneity between studies.

Assistive technology (AT) includes assistive products (APs) and related services that can improve health and well-being, enable increased independence and foster participation for people with functional difficulties, including older adults and people with impairments or chronic health conditions. This paper uses the umbrella term ‘functional difficulty’ (FD) to refer to all of these groups. This systematic review was undertaken to identify studies presenting population-based estimates of need and coverage for five APs (hearing aids, limb prostheses, wheelchairs, glasses and personal digital assistants) grouped by four functional domains (hearing, mobility, vision and cognition).

How do we support women and girls with disabilities to overcome stigma against them? - Evidence brief

Expand view

Stigma refers to the labelling of an individual or group of people in a way that ultimately denies them full social acceptance and equality of opportunity, and is often the root cause of discrimination and exclusion experienced by people with disabilities. The negative implications of stigma are far-reaching and profound, including limiting opportunities for accessing health care, education or livelihoods; affecting quality of life  and wellbeing, and increasing the risk of violence and abuse. Stigma is intersectional, meaning that women and girls with disabilities often experience several layers of discrimination, on account of both their disability and their gender. Reducing stigma experienced by women and girls with disabilities is therefore critical to supporting their full inclusion in society on an equal basis as others.

How can we overcome barriers to accessing rehabilitation for persons with disabilities in LMIC? - Evidence brief

MACTAGGART, Islay
April 2021

Expand view

Rehabilitation is described as a set of measures to optimise the functioning of individuals, and is important for wellbeing, participation and quality of life. Rehabilitation includes diagnosis, treatments, surgeries, assistive devices and therapies. Not all people who need rehabilitation are people with disabilities, and not all people with disabilities need rehabilitation. The World Health Organisation (WHO) recently estimated that 1 in 3 people globally (2.41 billion people) would benefit from rehabilitation: this number has increased nearly two thirds since 1990, due to population growth and increase in Non-Communicable Diseases (NCDs). In contrast, there are estimated to be less than 10 skilled rehabilitation practitioners per million population in Low and Middle Income Countries (LMICs), and only 5 – 15% of people in need of assistive devices are thought to have received them.

What evidence is there for the benefits of inclusive education for children without disabilities? - Evidence brief

STEFFEN, Liändrie
March 2021

Expand view

Inclusive education offers a variety of potential academic and social benefits for all students; with as well as without disabilities. However, a common concern among the non-disabled population is the potential negative impacts the inclusion of students with disabilities might have on their non-disabled classmates.  These negative beliefs and attitudes by parents and teachers can translate into a lack of implementation of inclusive education. There is substantial evidence for the benefits of inclusion for students with disabilities, however, there is very little evidence on the impact it has on non-disabled students, particularly in LMICs compared to HICs. This evidence brief explores evidence-based recommendations on the benefits of inclusive education for children without disabilities and how this issue shapes inclusive education implementation in LMICs.

What are the most effective strategies for strengthening health systems for disability inclusive development? - Evidence brief

MACTAGGART, Islay
February 2021

Expand view

Health system strengthening refers to initiatives that improve one or more functions of health systems, leading to better health. There is a large body of evidence on what works to strengthen health systems in low- and middle-income countries (LMICs), much of which is aligned to the World Health Organization (WHO) health system building blocks (service delivery; health workforce; information; medical products, vaccines and technologies; financing; and leadership/governance). Despite the fact that some people with disabilities have additional health needs, and many face additional barriers to accessing healthcare, inclusion of people with disabilities is largely missing from this evidence base. Separately, a smaller evidence base exists on increasing the effectiveness of specific health-related services targeting people with disabilities, such as health-related Community Based Rehabilitation (CBR), rehabilitation services more broadly, and mental health services. This second evidence base is less closely aligned to the building blocks. Reviewing these outputs in parallel goes some way towards identifying effective strategies for strengthening health systems for disability inclusive development.

Trends in prevalence of blindness and distance and near vision impairment over 30 years: an analysis for the Global Burden of Disease Study

To contribute to the WHO initiative, VISION 2020: The Right to Sight, an assessment of global vision impairment in 2020 and temporal change is needed. This paper aims to extensively update estimates of global vision loss burden, presenting estimates for 2020, temporal change over three decades between 1990–2020, and forecasts for 2050.

A systematic review and meta-analysis of population-based surveys of eye disease from January, 1980, to October, 2018 was carried out. Only studies with samples representative of the population and with clearly defined visual acuity testing protocols were included. Hierarchical models were fitted to estimate 2020 prevalence (with 95% uncertainty intervals [UIs]) of mild vision impairment (presenting visual acuity ≥6/18 and <6/12), moderate and severe vision impairment (<6/18 to 3/60), and blindness (<3/60 or less than 10° visual field around central fixation); and vision impairment from uncorrected presbyopia (presenting near vision <N6 or <N8 at 40 cm where best-corrected distance visual acuity is ≥6/12). We forecast estimates of vision loss up to 2050.

Expand view

PURPOSE

As the prevalence of age-related visual impairment increases, a greater understanding of the physiological and cognitive capacities that are recruited during braille reading and the potential implications of age-related declines is required.

 

METHODS

This scoping review aimed to identify and describe primary studies exploring the relationship between tactile, motor and cognitive capacities and braille reading performance, the instruments used to measure these capacities, and the extent to which age is considered within these investigations. English peer-reviewed articles exploring the relationship between these capacities and braille reading performance were included. Articles were screened by two researchers, and 91% agreement was achieved (kappa = 0.84 [0.81, 0.87], p < 0.01).

 

RESULTS

 2405 articles were considered of which 36 met the inclusion criteria. Fifteen investigated the relationship between tactile capacities and braille reading performance, 25 explored motor capacities, and 5 considered cognitive capacities. Nineteen instruments were used to measure tactile capacity, 4 for motor dexterity, and 7 for cognitive capacity. These studies focus on younger participants and on those who learned braille early in life.

 

CONCLUSIONS

  • Although this overview underscores the importance of tactile perception and bimanual reading, future research is needed to explore the unique needs of older adults who learn braille later in life.
  • The studies in this review underscore the importance of developing both haptic tactile perception and efficient hand reading patterns early in the braille learning process.
  • Practitioners should consider whether specific pre-braille readiness activities can be used to address the unique needs of older adults who may experience tactile, motor or cognitive declines.
  • Most of the studies in this review require replication before they should serve as reliable clinical guidelines; however, braille reading (like print) is a complex process that draws on multiple capacities that should be developed in unison.
  • The studies in this review focus heavily on younger participants and on those who learned braille early in life, and highlight the need for future research on braille and aging.

Persons with disabilities have the same sexual and reproductive health and rights (SRHR) as non-disabled persons. Yet they face numerous barriers in their access to sexual and reproductive health services and their rights are often not met. Evidence on SRHR for persons with disabilities is sparse, particularly evaluations of interventions demonstrating ‘what works.’ This systematic review assessed interventions to promote SRHR for persons with disabilities in low- and middle-income countries.

Background: Access to healthcare contributes to the attainment of health and is a fundamental human right. People with disabilities are believed to experience widespread poor access to healthcare services, due to inaccessible environments and discriminatory belief systems and attitudes. Qualitative data on these bar- riers has not previously been systematically reviewed. A meta-synthesis was undertaken of qualitative studies exploring the barriers to primary healthcare services experienced by people with disabilities in low- and mid- dle-income countries.

 

Methods: Six electronic databases were searched for relevant studies from 2000 to 2019. Forty-one eli- gible studies were identified.

 

Results: Findings suggest that the people with disabilities’ choice to seek healthcare services or not, as well as the quality of intervention provided by primary healthcare providers, are influenced by three types of barriers: cultural beliefs or attitudinal barriers, informational barriers, and practical or logis- tical barriers.

 

Conclusion: In order to achieve full health coverage at acceptable quality for people with disabilities, it is necessary not only to consider the different barriers, but also their combined effect on people with dis- abilities and their households. It is only then that more nuanced and effective interventions to improve access to primary healthcare, systematically addressing barriers, can be designed and implemented.

Differentiation and individualisation in inclusive education: a systematic review and narrative synthesis

SCHWAB, Susanne
2020

This study integrates research about differentiation and individualisation in inclusive education since the UN Convention on the Rights of Persons with Disabilities in 2006 (United Nations, 2006). The concept of inclusive education for all learners increases the requirement for teachers to create educational spaces that encourage stimulating teaching and learning processes. Accordingly, a methodological shift from the traditional ‘one-size-fits-all’ model to individualised teaching and learning offers a starting point for educational equity. The aim of this paper is to investigate the progress of differentiated and individualised teaching practices in inclusive classroom settings considering collaboration and teamwork, instructional practices, organisational practices and social/emotional/behavioural practices (see Finkelstein, Sharma, & Furlonger, 2019. “The Inclusive Practices of Classroom Teachers: A Scoping Review and Thematic Analysis.” International Journal of Inclusive Education, 1–28). Results of a criteria-based review considering papers from 2008 to December 2018 encompass 17 articles that were included in the narrative synthesis. Results indicated that the following aspects are characteristic of inclusive education: collaboration and co-teaching, grouping, modification (of assessment, content, extent, instruction, learning environment, material, process, product and time frame), individual motivation and feedback, and personnel support of students. Implications of the findings and gaps in the research have been outlined.

How can we ensure the safety and wellbeing of children with disabilities during humanitarian crises? - Evidence brief

This brief reviewed evidence-based recommendations on how to ensure the safety and wellbeing of children with disabilities in humanitarian settings. The right to safety for all is enshrined in Article 11 of the CRPD, yet this population has been consistently neglected in the global literature around children affected by disaster and crises, and as such the recommendations made are limited to specific humanitarian settings (e.g., natural disasters, war and conflict) and towards children with physical and mobility challenges. There is a need to further explore their diverse needs and experiences by recognising them as independent actors who can meaningfully participate in and contribute to the development of services and policies targeted towards them

How can we measure disability in research related to the COVID-19 response?

There is growing evidence that COVID-19 is disproportionally impacting the lives of people with disabilities. This includes evidence of the increased risk of severe outcomes of contracting COVID-19 amongst people with existing health conditions, including many people with disabilities. It also includes a wide range of other potential impacts such as: reductions or disruptions in non-COVID-19 health or rehabilitation services, the effects of shielding on isolation and mental health, the implications of social distancing on people who require carer support, and the impact on poverty, participation and wellbeing due to disrupted disability-inclusive development programmes.

 

Measurement of disability in research has historically been contested and a number of different tools exist. Clear guidance is needed on how to determine which tool to use to understand the situation of people with disabilities in different settings, and plan responsive and inclusive COVID-19 programmes and policies to support their needs. Good quality, comparable data on disability is essential for tracking the impact of the COVID-19 pandemic, as well as prevention and mitigation interventions, amongst people with disabilities. Such evidence is also imperative for tracking progress towards the Sustainable Development Goals, and UNCRPD compliance.

 

This evidence brief synthesises findings from a scoping review of ICF-compatible tools to measure disability in population-based surveys with a focus on LMICs (2018), protocols and research outputs from seven population-based surveys of disability across Asia, Africa and the Pacific, secondary analyses of the South African Census, US National Health Interview Survey and three Demographic and Health Surveys, reflections from global stakeholders in disability measurement (including the UN Flagship Report on Disability), and evidence compiled for the upcoming Global Disability Research Massive Open Online Course at the London School of Hygiene & Tropical Medicine

What do we know about how to support mental health and wellbeing during the COVID-19 pandemic from past infectious disease epidemics?

The question and the problem:

Symptoms of mental ill-health are common during widespread outbreak of an infectious disease, with high rates of depression, anxiety and post-traumatic stress disorder (PTSD) reported during recent epidemics, such as the recent Ebola crises and SARS-CoV-1. Elevated symptoms of mental ill-health are not limited to patients only, and are seen in healthcare workers, family members and indeed more widely across the general population. Early evidence coming from the COVID-19 pandemic demonstrates high rates of mental ill-health and mental health service provision is needed. This evidence brief summarises evidence on mental health support during COVID-19 and other recent pandemics, informing policy and practice during this crisis.

The outcomes of individualized housing for people with disability and complex needs: a scoping review

PURPOSE: Worldwide, disability systems are moving away from congregated living towards individualized models of housing. Individualized housing aims to provide choice regarding living arrangements and the option to live in houses in the community, just like people without disability. The purpose of this scoping review was to determine what is currently known about outcomes associated with individualized housing for adults with disability and complex needs.

 

METHODS: Five databases were systematically searched to find studies that reported on outcomes associated with individualized housing for adults (aged 18–65 years) with disability and complex needs.

 

RESULTS: Individualized housing was positively associated with human rights (i.e., self-determination, choice and autonomy) outcomes. Individualized housing also demonstrated favourable outcomes in regards to domestic tasks, social relationships, challenging behaviour and mood. However, outcomes regarding adaptive behaviour, self-care, scheduled activities and safety showed no difference, or less favourable results, when compared to group homes.

 

CONCLUSIONS: The literature indicates that individualized housing has favourable outcomes for people with disability, particularly for human rights. Quality formal and informal supports were identified as important for positive outcomes in individualized housing. Future research should use clear and consistent terminology and longitudinal research methods to investigate individualized housing outcomes for people with disability.

How can social protection responses to COVID-19 be made disability inclusive?

BANKS, Lena Morgon
HUNT, Xanthe
June 2020

Question & problem

The COVID-19 pandemic and strategies essential for its containment are resulting in severe strains on economies, particularly in low- and middle-income countries (LMICs). These impacts will be felt most by groups already in or at risk of poverty, including the estimated 1 billion people with disabilities globally. Interventions to address the short- and long-term economic effects of the pandemic are urgently needed. Some countries have begun implementing or announced plans for interventions addressing the economic impacts of COVID-19, such as food assistance, emergency cash transfers, unemployment assistance or expansions to existing social protection programmes. As these programmes are developed, it is important to consider the extent to which their design and delivery is inclusive of people with disabilities. Failure to adequately include people with disabilities in this process will lead to widening inequalities.

This Campbell systematic review and meta-analysis examines the impact of multifaceted interventions on community participation outcomes for adults with disabilities, and aims to find effective components of the interventions. The review summarizes the findings from 15 reports of multifaceted interventions in five countries (USA, China, Germany, Italy, Australia) with the majority from USA (10).

Included studies employ at least two interventions designed to address two or more participant characteristics (e.g., skill enhancement, behavior/attitude change) and/or environmental characteristics (e.g., participant interactions with people, places, or things) resulting in outcomes that provide direct access to the community (e.g., competitive employment, adult learning, housing) or are a dimension of community participation (e.g., self-determination, quality of life, social networking).

A total of 15 studies using a multifaceted intervention were included in this review. Of these, nine were randomized and six were quasi-experimental. Study participants were adults, 18 years or older, with a disability, who had exited secondary school services. Participants identified as having the following disabilities: intellectual disability, mental illness, traumatic brain injury, aging-related disabilities (e.g., dementia, Alzheimer’s, reduction in activities of daily living), or combinations of two or more classifications.

In recent years, more than 120 million people each year have needed urgent humanitarian assistance and protection. Armed conflict has profoundly negative consequences in communities. Destruction of civilian infrastructure impacts access to basic health services and complicates widespread emergency responses. The number of conflicts occurring is increasing, lasting longer and affecting more people today than a decade ago. The number of children living in conflict zones has been steadily increasing since the year 2000, increasing the need for health services and resources. This review systematically synthesised the indexed and grey literature reporting on the delivery of trauma and rehabilitation interventions for conflict-affected populations.

A systematic search of literature published from 1 January 1990 to 31 March 2018 was conducted across several databases. Eligible publications reported on women and children in low and middle-income countries. Included publications provided information on the delivery of interventions for trauma, sustained injuries or rehabilitation in conflict-affected populations. A total of 81 publications met the inclusion criteria, and were included in the review.

Expand view

Background: This research is part of a larger project on the exploration of inequalities in South African higher education. This current study focussed on the implementation of policies to eradicate inequalities in an inclusive education system.

 

Objectives: This article aimed to establish the implementation of policy by researching the lived experiences of students with specific learning disabilities (SLDs) studying in the university.

 

Method: A qualitative, systematic review was employed as the research methodology. Original peer-reviewed qualitative studies published between 1994 and 2017 were systematically reviewed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used to ensure rigorous reviews. The Critical Appraisal Skills Programme (CASP) was used to guide the process of critical appraisal of the selected articles which resulted in a total of 10 articles being selected for reviewing. The target population of this research comprised undergraduate students diagnosed with SLD. Semi-structured interviews were the main data collection tools used in the studies that were reviewed. Data from the selected articles were extracted and synthesised.

 

Results: The dominant themes that emerged from the review were: (1) fear of stigmatisation; (2) gaps in policy implementation; (3) experiences vary across departments; and (4) self-determination and family support as success factors.

 

Conclusion: An important aspect in the transformation of higher education institution is to ensure the closing of the disjuncture between policy and implementation in support of students with SLD.
