The need for a Rehabilitation Model to address the disparities of public healthcare for people living with HIV in South Africa

Disability, a priority area for health research in South Africa: an analysis of the burden of disease study 2017

PURPOSE

Disabilities are increasing globally, which is attributed to the overall ageing of populations in affluent countries. This trend may differ in low and middle-income countries. This paper assesses the change over time in Years Lived with Disability (YLD) for South Africa and how this compares to regional and global trends.

MATERIALS AND METHODS

This secondary analysis of the Global Burden of Disease Study 2017 dataset describes the observed contribution of YLD to Disability-Adjusted Life Years (DALYs) per 100 000 people over the period 1990-2016, and forecast to 2030 using simple linear prediction. South African trends are compared to global and sub-Saharan African (SSA) trends to highlight the effect of HIV and policy implications.

RESULTS

Globally, the contribution of YLD to DALYs has increased from ±21.7% in 1990 to ±34% by 2016, with high socio-demographic index countries having a higher contribution (49%). HIV, mental health, musculoskeletal, neurological, and sense organ disorders are the five main contributors to YLD in South Africa (54%). Removing the effects of HIV/AIDS and sexually transmitted infections on YLD, South Africa's trend appears similar to the global trend, yet opposite to the SSA trend.

CONCLUSION

Our analysis shows there is a growing burden of disability in South Africa. Differences in trends with the regional and global patterns can be attributed to the high burden of HIV and non-communicable diseases in South Africa. Therefore, strategies are urgently needed to increase integration of disability and rehabilitation services into chronic HIV and non-communicable disease management. This calls for disability screening to identify functional limitations in routine data collection and case management.IMPLICATIONS FOR REHABILITATIONSouth Africa has experienced an increase in disability prevalence over time.This requires strengthening of services such as mental health interventions, physiotherapy, optometry, and audiology, and linking major disease clusters, such as HIV and the NCDs, to rehabilitation services.The greatest contributors towards disability adjusted life years in South Africa are currently mental disorders (13.8%), HIV and sexually transmitted infections (11.8%), musculoskeletal disorders (10.4%), neurological disorders (8.2%), and sense organ diseases (7.5%).Routine data collection and case management needs to include disability screening to identify developing functional limitations.

HIV-related disability and rehabilitation: perception of health care workers

Background: Health care workers play an integral role in the rehabilitation and care of people living with HIV who face multiple impairments and often disabilities. The aim of the article was to understand the perceptions and attitudes of health care workers towards caring for people living with HIV, and experiencing disability. Methods: Fifteen health care workers offering care to people living with HIV were interviewed using a semi-structured guide. These health care workers included doctors, a social worker, a pharmacist, a dietician, an occupational therapist, a physiotherapist, and nurses and HIV couPnsellors who were employed at a public health care facility in KwaZulu-Natal. Data from the interviews were transcribed and analysed using conventional content analysis. Results: Four themes emerged from semi-structured interviews with the health care workers: a holistic disability framework, a multidisciplinary team dynamic, organisational barriers and recommendations by health care workers. Conclusion: Health care workers perceived a shift from a biomedical perspective of disability to a bio-psychosocial interpretation that is influenced by contextual and environmental barriers imposed by communities on people living with HIV. Barriers included stigmatisation that leads to attitudinal barriers and social exclusion of people living with HIV and experiencing disabilities within communities. Lack of resources, including of equipment, and a shortage of health care staff also posed barriers to the care offered to people living with HIV and experiencing disabilities. Participants agreed that improved communication in the multidisciplinary health care team, as well as continuing education and training, would enable health care workers to offer improved, integrated care to people living with HIV who experience disabilities.

A Rehabilitation Framework for Children Living With HIV in South Africa: Reaching Consensus for a Resource-Poor Community

Although rehabilitation frameworks for adults living with HIV are developing steadily, interventions to ensure the integration of rehabilitation into the routine care of children living with HIV-related disabilities lags. We sought to explore perceptions of, and gain expert consensus on, a rehabilitation framework for children living with HIV. Experts in HIV pediatric care in South Africa engaged in a Delphi survey, based on findings from a context-specific rehabilitation framework for adults. Consensus was determined by an a priori threshold of 80% agreement and an interquartile range of 1 or lower on criteria to be included as essential or useful in the framework. Experts agreed that enhancing access to patient-centered care through decentralization and training of health care and community care workers in the use of disability screening tools at each point of care needed to be included in the framework. Strengthening multiprofessional team collaboration was also seen as fundamental.

Child functioning and disability in children living with human immunodeficiency virus in a semi-rural healthcare setting in South Africa

Background

Children living with HIV (CLHIV) often experience HIV-related impairment and disability.

Aim

The study sought to understand the level of child functioning and access to rehabilitative care in the context of South African healthcare in order to inform an integrated rehabilitative framework.

Setting

District level semi-rural healthcare facility in KwaZulu-Natal.

Methods

The Washington Group/United Nations International Children’s Emergency Fund Module on Child Functioning, was administered to carers of CLHIV aged between 5 and 10 years, and accessing care at the study setting.

Results

Forty-four caregivers of children receiving treatment from June 2018 to March 2019, at the facility, participated. Four (9.1%) children had difficulty with seeing, 13 (29.5%) children had difficulty with hearing and 10 (22.7%) children had difficulty with walking. In the cognitive and behavioural domains, 17 (38.6%) children reported difficulties in communication and concentration, with 16 (36.4%) children experiencing difficulties in learning and remembering. Difficulties reported in accepting change and controlling behaviour were both experienced by 23 (52.3%) children. Although many children experiencing impairments were referred for rehabilitation, many caregivers did not follow-up after the initial assessment, because of financial constraints, lack of time and transport restrictions.

Conclusion

Functional difficulties were frequently experienced by children living with HIV. Disability screening would be beneficial at various points of care to promote early identification and timely referral to healthcare professionals. Decentralising rehabilitative care to homes and communities could offer a solution to some of the reported barriers to accessing care.

Recommendations for integrating physiotherapy into an interprofessional outpatient care setting for people living with HIV: a qualitative study

OBJECTIVES

To identify factors to consider when integrating physiotherapy (PT) into an interprofessional outpatient HIV care setting from the perspective of healthcare professionals and adults living with HIV.

DESIGN

We conducted a qualitative descriptive study using semi-structured interviews (healthcare professionals) and focus groups (adults living with HIV). We asked participants their perspectives on barriers, facilitators and strategies to accessing and participating in outpatient PT, important characteristics physiotherapists should possess working in outpatient HIV care, content and structure of PT delivery, and programme evaluation.

RECRUITMENT AND SETTING

We purposively sampled healthcare professionals based on their experiences working in interprofessional HIV care and recruited adults with HIV via word of mouth and in collaboration with an HIV-specialty hospital in Toronto, Canada. Interviews were conducted via Skype or in-person and focus groups were conducted in-person at the HIV-specialty hospital.

PARTICIPANTS

12 healthcare professionals with a median of 12 years experience in HIV care, and 13 adults living with HIV (11 men and 2 women) with a median age of 50 years and living with a median of 6 concurrent health conditions in addition to HIV.

RESULTS

Overall impressions of PT in outpatient HIV care and factors to consider when implementing PT into an interprofessional care setting include: promoting the role of, and evidence for, PT in outpatient HIV care, structuring PT delivery to accommodate the unique needs and priorities of adults living with HIV, working collaboratively with a physiotherapist on the healthcare team and evaluating rehabilitation as a component of interprofessional care.

CONCLUSIONS

Multiple factors exist for consideration when implementing PT into an interprofessional outpatient HIV care setting. Results provide insight for integrating timely and appropriate access to evidence-informed rehabilitation for people living with chronic and episodic illness, such as HIV.

Looking at antiretroviral adherence through a disability lens: a cross-sectional analysis of the intersection of disability, adherence, and health status

Background: Antiretroviral adherence is vital to the successful long-term rollout of the antiretroviral therapy program in South Africa. At present, there are no studies that look at the effects of disability on antiretroviral adherence.Methods: Drawing on the baseline data from an existing cohort of 1042 people on antiretrovirals in a public healthcare setting in KwaZulu-Natal, the paper investigated a variety of existing covariates relating to antiretroviral adherence, together with functional limitations, depressive symptoms, and health symptoms. Disability was defined according to the International Classification of Functioning, Disability, and Health framework and measured using the World Health Organization Disability Assessment Schedule.Results: In a proportional odds logistic regression functional limitations, depressive symptoms, health symptoms and gender emerged as significant associated with decreased adherence to antiretrovirals (Odds ratio [95% confidence interval]: 1.86 [1.31, 2.66], 1.61 [1.02, 2.55], 2.33 [1.47, 3.69], and 1.65 [1.16, 2.35], respectively). This was found for both severe and milder forms of functional limitations/disability.Conclusion: The paper highlights the need to better understand the role of these limitations in achieving adequate adherence to antiretrovirals and viral suppression. It also calls for investigations into integrated mitigating services such as integrating rehabilitation into routine human immunodeficiency virus care.Implications for RehabilitationThis study provides a starting point to understand the association between functional limitations and challenges in maintaining adherence to antiretroviral therapy.Addressing functional limitations is currently a neglected factor in efforts targeting HIV-treatment adherence and retention.Rehabilitation is a key intervention that could address this gap.Even mild forms of disability can have profound effects on adherence to antiretroviral therapy, which highlights the need for better screening, early identification, and referrals to rehabilitative support and treatment.

A study protocol "saving futures: developing an integrated model of rehabilitation and paediatric HIV care to foster success at school"

BACKGROUND

A significant number of children experience disabilities as a result of living with HIV, including those on antiretroviral therapy (ART). Current paediatric HIV care does not prioritise rehabilitation. Furthermore, little attention is paid to cognitive development and educational needs, thereby placing the future of these children at risk. This can be mitigated by providing rehabilitation services to help overcome these disabilities.

METHODS

The study will assess the feasibility (acceptability, practicality, preliminary efficacy) of an integrated model of rehabilitation and paediatric HIV care in order to improve diagnosis and interventions for disability amongst children living with HIV between the ages of 5 and 10 years. The model will integrate data entry and management tools, improving identification, referral, and linkage to care, with an intervention approach that can be used by trained lay health professionals. The study targets both physical and cognitive impairments that lead to disabilities to improve school readiness and success. Phase 1 will inform the design of an optimal integrated model of rehabilitation and paediatric HIV care in a public healthcare setting in South Africa. The study will first undertake a formative investigation of the factors impacting integration of rehabilitation with paediatric HIV care from the perspective of caregivers and health professionals. It will use qualitative methods, including in-depth interviews and focus group discussions. The knowledge from this phase will inform the design of the model in phase 2, and phase 3 will pilot the integrated rehabilitation and paediatric HIV model with the aim to improve school readiness for the participants at the study site. The pilot intervention will be formally evaluated.

DISCUSSION

The results from this study will determine whether the model has potential for widespread application in South African paediatric HIV care and recommend further possible modifications. This will inform the development of a proposal to support the current government initiative to strengthen disability and rehabilitation services. The study results will also inform South Africa's current efforts to strengthen early interventions for children with disabilities and will be an important and critically needed step in the use of rehabilitation to strengthen paediatric HIV care in the region.

Assessing home-based rehabilitation within the development of an integrated model of care for people living with HIV in a resource-poor community

Background

People living with HIV (PLHIV) are living longer lives but are at a greater risk of developing disability. South Africa has the largest antiretroviral therapy (ART) programme in the world, shifting HIV from a deadly to a chronic disease. The integration of rehabilitation into chronic care is therefore now crucial to ensure the highest quality of life of PLHIV.

Aim

To describe how a home-based rehabilitation (HBR) programme adhered to the fundamental principles of a theoretical model of integrated care developed for the study setting in KwaZulu-Natal, South Africa.

Method

The process and results from the HBR programme were assessed in relation to the model of care to ascertain which principles of the model were addressed with the HBR programme and which elements require further investigation.

Results

The HBR programme was able to apply a number of principles such as evidence-based practice, task shifting to lay personnel, enabling patient-centred care and maximising function and independence of PLHIV. Other elements such as the adoption of a multidisciplinary approach, training on the use of disability screening tools and the use of evidence to influence policy development were more difficult to implement.

Conclusion

It is possible to implement elements of the integrated model of care. Further research is needed to understand how principles that require further training and collaboration with other stakeholders can be implemented. The results of this study provide additional evidence towards understanding the feasibility of the theoretical model and what is required to adjust and test the full model.

Knowledge of HIV-related disabilities and challenges in accessing care: Qualitative research from Zimbabwe

Introduction

While the rapid expansion in antiretroviral therapy access in low and middle income countries has resulted in dramatic declines in mortality rates, many people living with HIV face new or worsening experiences of disability. As nearly 1 in 20 adults are living with HIV in sub-Saharan Africa–many of whom are likely to develop disabling sequelae from long-term infection, co-morbidities and side effects of their treatment–understanding the availability and accessibility of services to address HIV-related disabilities is of vital importance. The aim of this study thus is to explore knowledge of HIV-related disabilities amongst stakeholders working in the fields of HIV and disability and factors impacting uptake and provision of interventions for preventing, treating or managing HIV-related disabilities.

Methods

In-depth, semi-structured interviews were conducted with ten stakeholders based in Harare, Zimbabwe, who were working in the fields of either disability or HIV. Stakeholders were identified through a priori stakeholder analysis. Thematic Analysis, complemented by constant comparison as described in Grounded Theory, was used to analyse findings.

Results

All key informants reported some level of knowledge of HIV-related disability, mostly from observations made in their line of work. However, they reported no interventions or policies were in place specifically to address HIV-related disability. While referrals between HIV and rehabilitation providers were not uncommon, no formal mechanisms had been established for collaborating on prevention, identification and management. Additional barriers to accessing and providing services to address HIV-related disabilities included: the availability of resources, including trained professionals, supplies and equipment in both the HIV and rehabilitation sectors; lack of disability-inclusive adaptations, particularly in HIV services; heavy centralization of available services in urban areas, without accessible, affordable transportation links; and attitudes and understanding among service providers and people living with HIV-related disabilities.

Conclusions

As people living with HIV are surviving longer, HIV-related disabilities will become a major source of disability globally, particularly in sub-Saharan Africa where infection is endemic. Preventing, treating and managing HIV-related disabilities must become a key component of both HIV response efforts and rehabilitation strategies.

Home-based rehabilitation interventions for adults living with HIV: a scoping review

Home-based rehabilitation (HBR) has been shown to improve the lives of people living with a wide range of chronic diseases in resource-rich settings. This may also be a particularly effective strategy in resource-poor settings, where access to institution-based rehabilitation is limited. This review aimed to summarise and discuss the evidence related to the effectiveness of home-based rehabilitation (HBR) interventions designed specifically for adults living with HIV. A scoping review methodology was employed, involving systematic search techniques and appraisal of appropriate evidence. English-language journal articles that assessed the quality of life or functional ability outcomes of HBR interventions for adults living with HIV were considered for this review. Out of an initial 1 135 publications retrieved from the search of databases, six articles met this review's inclusion criteria. While this review highlights the scarcity of empirical evidence related to HBR interventions for adults living with HIV, the findings of these six articles are that HBR is a safe management option that may confer a number of physical and psychological benefits for this population. Future research on HBR interventions should include a wider range of assessment measures, including cost-benefit analyses and specific tools designed to assess the functional ability and participation in activities of daily living of participants involved in these programmes. In particular, more research on HBR is required in resource-poor environments, such as sub-Saharan Africa where HIV is endemic, to assess whether this is a feasible strategy that is both effective and practical in the areas that may need it most.

A rehabilitation model as key to comprehensive care in the era of HIV as a chronic disease in South Africa

In the era of widespread access to antiretroviral therapy, people living with HIV survive; however, this comes with new experiences of comorbidities and HIV-related disability posing new challenges to rehabilitation professionals and an already fragile health system in Southern Africa. Public health approaches to HIV need to include not only prevention, treatment and support but also rehabilitation. While some well-resourced countries have developed rehabilitation approaches for HIV, resource-poor settings of Southern Africa lack a model of care that includes rehabilitation approaches providing accessible and comprehensive care for people living with HIV. In this study, a learning in action approach was used to conceptualize a comprehensive model of care that addresses HIV-related disability and a feasible rehabilitation framework for resource-poor settings. The study used qualitative methods in the form of a focus group discussion with thirty participants including people living with HIV, the multidisciplinary healthcare team and community outreach partners at a semi-rural health facility in South Africa. The discussion focused on barriers and enablers of access to rehabilitation. Participants identified barriers at various levels, including transport, physical access, financial constraints and poor multi-stakeholder team interaction. The results of the group discussions informed the design of an inclusive model of HIV care. This model was further informed by established integrated rehabilitation models. Participants emphasized that objectives need to respond to policy, improve access to patient-centered care and maintain a multidisciplinary team approach. They proposed that guiding principles should include efficient communication, collaboration of all stakeholders and leadership in teams to enable staff to implement the model. Training of professional staff and lay personnel within task-shifting approaches was seen as an essential enabler to implementation. The health facility as well as outreach services such as intermediate clinics, home-based care, outreach and community-based rehabilitation was identified as important structures for potential rehabilitation interventions.

A Home-Based Rehabilitation Intervention for Adults Living With HIV: A Randomized Controlled Trial

A randomized controlled trial was conducted to investigate the effects of a 16-week home-based rehabilitation (HBR) intervention on the quality of life, functional mobility, and functional capacity of adult people living with HIV (PLWH) on antiretroviral therapy in KwaZulu-Natal, South Africa. The intervention was carried out by community health care workers under the supervision of a qualified physical therapist. Participants in the control group received the standard of care as well as written health advice. While participants in the intervention group showed greater improvements across all outcome measures, between-group differences were nonsignificant. HBR for PLWH is a safe means of addressing the functional deficits experienced by PLWH and appears likely to improve quality of life. A task-shifting approach may be a feasible method of meeting the varied needs of PLWH, while at the same time potentially minimizing costs to already overburdened health care systems.

Expert Consensus on the Rehabilitation Framework Guiding a Model of Care for People Living With HIV in a South African Setting

Disabilities and treatments related to HIV are a focus for rehabilitation professionals in HIV-endemic countries, yet these countries lack guidance to integrate rehabilitation into a model of care for people living with HIV. We asked HIV and rehabilitation experts in South Africa to engage in a modified Delphi survey based on findings from (a) an enquiry into stakeholder perspectives of a context-specific rehabilitation framework at a semi-rural setting and (b) an analysis of international models of care-guiding rehabilitation. Consensus was determined by an a priori threshold of 70% of agreement and interquartile range (≤ 1 on criterion) to be included as essential or useful in the model of care framework. Experts agreed that improving access to care, optimal communication between stakeholders, education and training for health care workers, and home-based rehabilitation were essential for the model. Furthermore, task shifting and evidence-based practice were seen as fundamental for optimal care.
