Disability and Living with HIV: Baseline from a Cohort of People on Long Term ART in South Africa

Effectiveness of a task-sharing collaborative care model for the detection and management of depression among adults receiving antiretroviral therapy in primary care facilities in South Africa: A pragmatic cluster randomised controlled trial

BACKGROUND

HIV is characterised by high rates of comorbidity with mental health conditions including depression, as such, the detection and treatment of comorbid depression is critical to achieve viral load suppression. This study evaluated the effectiveness of a collaborative care intervention for depression among adults with comorbid depression symptoms receiving ART in primary health care (PHC) facilities.

METHODS

We conducted a pragmatic cluster-randomised trial in 40 clinics in the North West province of South Africa. PHC clinics were stratified by sub-district and randomised in a 1:1 ratio. Participants were ≥ 18 years, receiving ART, and had depression symptoms indicated by Patient Health Questionnaire-9 (PHQ-9) score ≥ 9. Intervention clinics received: i) supplementary mental health training and clinical communication skills for PHC nurses; ii) workshops for PHC doctors on treating depression; and iii) lay counselling services. Using mixed effects regression models, we assessed co-primary outcomes of PHQ-9 response at 6 months (≥50 % reduction in baseline PHQ-9 score) and viral load suppression at 12 months (viral load<1000 copies/mL).

RESULTS

The intervention had no effect in PHQ-9 response (49 % vs 57 %, risk difference (RD) = -0.08, 95 % CI = -0.19; 0.03, p = 0.184) or viral load suppression (85 % vs 84 %, RD = 0.02, 95 % CI = -0.01; 0.04, p = 0.125). Nurses referred 4298 clinic patients to counsellors, however, only 66/1008 (7 %) of intervention arm participants were referred to counsellors at any point during the study.

LIMITATIONS

The highly pragmatic approach of this trial limited exposure to the counselling component of the intervention and referral to doctors for initiation of antidepressant treatment was extremely low.

CONCLUSION

The trial showed no effect of a district-based intervention to strengthen collaborative care for depression. The trial revealed the extent of the treatment gap in the context of scaling up mental health services.

Disrupted HIV care during COVID-19 pandemic associated with increased disabilities among people living with HIV in Belize

The COVID-19 pandemic may have impacted disabilities among people living with HIV; however, data on the association between COVID-19 pandemic-related healthcare disruptions and disabilities among people living with HIV is limited. We aimed to evaluate the association between COVID-19-affected HIV care behaviors and disability domains among people living with HIV in Belize. A cross-sectional study was conducted at the Western Regional Hospital and Southern Regional Hospital between August and October 2021 among people living with HIV in Belize aged ≥ 21 years and on antiretroviral therapy. A self-reported questionnaire captured data on demographic and clinical characteristics (gender, age, ethnicity, marital status, employment, education, CD4 count, and viral load), COVID-19-affected HIV care behaviors, and disability across six domains (physical, cognitive, and mental-emotional symptoms and impairments; uncertainty; difficulties carrying out day-to-day activities; and social inclusion challenges) using the Short-Form HIV Disability Questionnaire. Univariate and multivariate logistic regression analyses were employed to analyze the data. Of the 489 participants, 276 (56.4%) were women and 213 (43.6%) were men. After adjusting for covariates, (age, gender, employment, CD4 count, viral load, COVID-19-affected HIV care behaviours), our results showed that people living with HIV, whose HIV care behaviors were greatly affected by COVID-19, were more likely to have disabilities across various domains: physical (adjusted odds ratio (AOR): 1.61, 95% confidence interval (CI): 1.08-2.41, p = 0.018), cognitive (AOR: 2.49, 95% CI: 1.58-3.94, p < 0.001), uncertainty (AOR: 2.94, 95% CI: 1.68-5.12, p < 0.001), difficulties carrying out day-to-day activities (AOR: 1.69, 95% CI: 1.06-2.69, p = 0.027), and social inclusion challenges (AOR: 1.89, 95% CI: 1.27-2.81, p = 0.002). Mitigating disruptions in care behaviors through the implementation of more accessible and comprehensive healthcare services may potentially address the multifaceted nature of HIV disabilities.

The association between HIV infection, disability and lifestyle activity among middle-aged and older adults: an analytical cross-sectional study in Ivory Coast (the VIRAGE study)

INTRODUCTION

People living with HIV (PLWH) live longer and face new health challenges resulting from the confluence of chronic HIV infection and the natural effect of aging and comorbidities. However, there is a dearth of information on the long-term impact of HIV infection on the health and wellbeing of PLWH in sub-Saharan Africa. This research aimed to fill this gap by reporting on physical, functional and social outcomes among PLWH treated at a referral center in Abidjan, Ivory Coast, and comparing them with those of a control group.

METHODS

Body composition, functional capacity, sarcopenia, limitations in daily activities and social participation were assessed among 300 PLWH (aged ≥ 30 years) and 200 uninfected adults of similar age and sex. The associations between these outcomes and participants' socioeconomic characteristics, HIV history and physical activity level were assessed using generalized additive models adjusted for age and sex.

RESULTS

The median age was 51 years, and the median antiretroviral therapy duration was 15 years. Compared to controls, PLWH reported higher levels of physical activity (p < 0.0001). They had a lower muscle index (adjusted p < 0.0001) and grip strength (adjusted p < 0.0001) but achieved similar performance on the 6-min walk test (6MWT, p = 0.2). Among PLWH, physical activity level was positively associated with better performance in the 6MWT (p = 0.006) and greater hand grip strength (p = 0.04). The difference in physical performance according to the level of physical activity appeared mainly after the age of 60. PLWH reported similar rates of activity limitations (p = 0.8), lower depression levels and greater scores for social functioning (p = 0.02).

CONCLUSION

In this study, PLWH achieved high levels of physical activity, which may explain why they maintained good physical performance and social functioning despite having a higher risk of sarcopenia. These results have important implications for resource-limited health systems and show avenues for chronic care models.

HIV advocacy: knowledge translation and implementation at three diverse sites in sub-Saharan Africa

PURPOSE

To explore how the gap in knowledge translation around HIV and rehabilitation could be addressed using advocacy. This article describes and reflects on lessons learned from incorporating content on HIV and advocacy into the curricula at three diverse physiotherapy (PT) programs in sub-Saharan Africa.

METHODS

A realistic evaluation approach was followed. Three study sites were purposively chosen to reflect diverse settings with respect to pedagogical approach, university or college, degree or diploma programs, use of technology, and regional prevalence of HIV. A multi-faceted intervention was implemented that included three activities: (i) to develop three core components of a novel knowledge translation intervention designed to improve knowledge, attitudes, and self-efficacy in HIV and rehabilitation advocacy among PT students; (ii) to tailor and implement the knowledge translation intervention by local faculty according to the context and needs of their program and to implement this with a cohort of PT students at each of the three study sites; and (iii) to evaluate the adaptation and implementation of the intervention at each site.

RESULTS

Differences exist between the three-country programmes, specifically in the length of time the degree takes, the extent of HIV inclusion in the curriculum and years of the study included in the project.

CONCLUSIONS

This research adds to the call to shift the focus of HIV care from just test-and-treat, or on just keeping people alive, towards a broader approach that centres the whole person, that focuses not only on surviving but on thriving, and which commits to the goal of optimising functioning and living full, whole lives with HIV. Advocacy across the continuum of care plays a pivotal role in translating research findings into practice.Implications for rehabilitationResults are relevant for policymakers in government and at senior levels within universities whose mandates include informing, reviewing, and driving educational programs and curricula.The result from this project illuminates the role for rehabilitation and allows for incorporating HIV into curriculum and practice for physiotherapists and other related stakeholders so that they can advocate for and with patients.

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.

Gendered differences in perceptions and reports of wellbeing: A cross-sectional survey of adults on ART in Malawi

Few studies have examined gender differences in reported quality of life among persons living with HIV (PLWH) in low-income countries. We conducted a cross-sectional survey of adults on antiretroviral therapy in Malawi, including questions focused on wellbeing, and collected clinical data on these respondents. We compared men's and women's self-reported health and wellbeing using Poisson models that included socio-demographic covariates. Approximately 20% of respondents reported at least one physical functioning problem. In multiple variable models, men were significantly more likely to have a high viral load (≥200 copies/mL; aIRR 2.57), consume alcohol (aIRR 12.58), receive no help from family or friends (aIRR 2.18), and to feel worthless due to their HIV status (aIRR 2.40). Men were significantly less likely to be overweight or obese (aIRR 0.31), or report poor health (health today is not "very good;" aIRR 0.41). Taken together, despite higher prevalence of poor self-rated health, women were healthier across a range of objective dimensions, with better viral suppression, less alcohol use, and less social isolation (although they were more likely to have an unhealthy BMI). Research that includes multi-dimensional and gender-specific measurement of physical, mental and social health is important for improving our understanding of well-being of PLWH.

Views of community health workers on the integration of a physiotherapist into a ward-based outreach team

Background

Due to changes in the disease profile and lifestyle of individuals in South Africa, the limited health care facilities available have experienced congestion and overcrowding, affecting health care service delivery. Ward-based outreach team (WBOT) programmes were implemented to strengthen primary health care, improve access and alleviate the congestion occurring at these facilities. However, WBOTs have limitations in terms of medical knowledge and rehabilitative skills.

Objective

To explore the views of community health workers (CHWs) on the integration of physiotherapists into WBOTs.

Method

A qualitative research design making use of focus group discussions (FGDs) was used. Through purposive sampling, 58 CHWs who were members of WBOTs were recruited. The WBOTs were from 10 selected primary health care centres in the Tshwane district, Region 2. Six FGDs were conducted. The audio-recorded data were transcribed verbatim. The transcripts were transported into NVivo 12 for thematic analysis.

Results

The views of the CHWs were that the WBOTs can benefit from having a physiotherapist as a member of the team. The WBOTs do not have adequate skills to attend to the physiotherapy needs of communities. People in the community have challenges in accessing physiotherapy services, and physiotherapy services can enhance the performance of the WBOTs by providing training to the WBOTs and providing clinical services to community members.

Conclusion

Community-based rehabilitative services with a physiotherapist as part of the WBOTs can enhance and strengthen the services of the WBOTs, which can improve the treatment outcomes for communities.

Clinical implications

The WBOTS will be empowered to provide clinical services to the vulnerable people in the community that they serve.

Alcohol and falls among people with HIV infection: A view from Russia and the United States

BACKGROUND

Both human immunodeficiency virus (HIV) infection and alcohol use predispose to autonomic/sensory neuropathy, imbalance symptoms, and cognitive impairment-conditions associated with a greater risk of falls-yet it is unclear how to identify people with HIV (PWH) whose drinking is associated with falls. Research on alcohol and falls using the same instruments in different countries could help to specify the level of alcohol use associated with fall risk. We examined whether a consumption-based measure (the Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]) and/or a symptom-based measure (DSM-5 criteria for alcohol use disorder [AUD]) are associated with sustaining a fall among PWH in St Petersburg, Russia and Boston, Massachusetts in the United States.

METHODS

Separate multivariate logistic regressions were used for each cohort to examine cross-sectional associations for each alcohol measure predicting fall. Potential confounders included physical functioning, depressive symptoms, and other substance use (measured with the Addiction Severity Index).

RESULTS

A fall was reported by 35% (87/251) of the sample in Boston and 12% (46/400) in St Petersburg. Each additional AUD criterion-but not higher AUDIT-C score-was significantly associated with a fall in both Boston (odds ratio [OR] = 1.10; 95% confidence interval [CI] 1.02, 1.18) and St Petersburg (adjusted OR AOR = 1.10; 95% CI 1.02, 1.18). Heavy alcohol use (>6 drinks/occasion, any vs. none) was associated with more than twice the odds of a fall (AOR = 2.24; 95% CI 1.21, 4.13) in Boston.

CONCLUSIONS

These findings suggest that while fall risk may vary by setting and population, heavy alcohol use and AUD symptom severity are potential targets for interventions to prevent falls. Studies in diverse global settings advance our understanding of the relationship between alcohol and falls in PWH.

Prevalence, severity, and risk factors of disability among adults living with HIV accessing routine outpatient HIV care in London, United Kingdom (UK): A cross-sectional self-report study

BACKGROUND

The study objectives were to measure disability prevalence and severity, and examine disability risk factors, among adults living with HIV in London, United Kingdom (UK).

METHODS

Self-reported questionnaires were administered: World Health Organization Disability Assessment Schedule 2.0 (WHODAS), HIV Disability Questionnaire (HDQ), Equality Act disability definition (EADD), and demographic questionnaire. We calculated proportion (95% Confidence Interval; CI) of "severe" and "moderate" disability measured using EADD and WHODAS scores ≥2 respectively. We measured disability severity with HDQ domain severity scores. We used demographic questionnaire responses to assess risk factors of "severe" and "moderate" disability using logistic regression analysis, and HDQ severity domain scores using linear regression analysis.

RESULTS

Of 201 participants, 176 (87.6%) identified as men, median age 47 years, and 194 (96.5%) virologically suppressed. Severe disability prevalence was 39.5% (n = 79/201), 95% CI [32.5%, 46.4%]. Moderate disability prevalence was 70.5% (n = 141/200), 95% CI [64.2%, 76.8%]. Uncertainty was the most severe HDQ disability domain. Late HIV diagnosis was a risk factor for severe disability [Odds Ratio (OR) 2.71; CI 1.25, 5.87]. Social determinants of health, economic inactivity [OR 2.79; CI 1.08, 7.21] and receiving benefits [OR 2.87; CI 1.05, 7.83], were risk factors for "severe" disability. Economic inactivity [OR 3.14; CI 1.00, 9.98] was a risk factor for "moderate" disability. Economic inactivity, receiving benefits, and having no fixed abode were risk factors (P≤0.05) for higher HDQ severity scores in physical, mental and emotional, difficulty with day-to-day activities, and challenges to social participation domains. Personal factors, identifying as a woman and being aged <50 years, were risk factors (P≤0.05) for higher HDQ severity scores in mental and emotional, uncertainty, and challenges with social participation domains.

CONCLUSIONS

People living with well-controlled HIV in London UK experienced multi-dimensional and episodic disability. Results help to better understand the prevalence, severity, and risk factors of disability experienced by adults living with HIV, identify areas to target interventions, and optimise health and functioning.

The Lived Experience of a Newly Diagnosed Older Person With HIV in Ukraine

Low- and middle-income countries are home to 80% of older people with HIV (OPWH). Ukrainian OPWH experience higher mortality and decreased antiretroviral therapy (ART) initiation than younger patients, but there is little data examining OPWH's perspectives around new diagnosis and impact on care. In this study, we examined accounts of 30 newly diagnosed OPWH in Ukraine, exploring challenges faced in the peri-diagnosis period. Themes emerged representing the longitudinal coping process: OPWH (1) viewed themselves as low risk before diagnosis; (2) experienced HIV diagnosis as a traumatic event challenging their self-image; (3) used disclosure to seek support among a small circle of family, friends, or health care providers; (4) avoided disclosure to outsiders including primary care providers for fears of stigma and breaches in confidentiality; (5) viewed age as an asset; and (6) used HIV diagnosis as starting point for growth. These findings highlight the need for age-specific programming to increase HIV knowledge and coping, increase screening, and improve long-term planning.

Facing the quality of life: physical illness, anxiety, and depression symptoms among people living with HIV in rural Zambia - a cross-sectional study

Widespread access to ART has not improved the quality of life (QoL) for people living with HIV (PLHIV). We used the United Nations Disability project (UNPRPD) evaluation data to examine how physical illness, anxiety, and depression shape the QoL of PLHIV in households receiving the social cash transfers safety nets in Luapula, Zambia. We explored associations between each outcome - physical illness, anxiety, depression symptoms - and age, gender, poverty, hunger and disability, using univariable and multivariable regressions. We adjusted p-values for multiple hypothesis testing with sharpened Qs. The sample comprised 1925 respondents 16-55 years old, median age 31 (IQR 22-42 years), majority women (n = 1514, 78.6%). Two-thirds (1239, 64.4%) reported having a physical illness, a third (671, 34.9%) anxiety, and nine per cent (366) depression symptoms. More HIV positive people had a disability (34.6%, 53 versus 28.3%, 502; Q = 0.033), were physically ill (72.5%, 111 versus 63.7%, 1128; Q = 0.011), and two-fold (aOR 1.97 95% CI 1.31-2.94) more likely to report depression symptoms than HIV negative peers. Food insecurity and disability among PLHIV may worsen their physical illnesses, anxiety, depression symptoms, and other QoL domains. More research on the quality of life of PLHIV in poverty is required.

Comparative analysis of the health status of the population in six health zones in South Kivu: a cross-sectional population study using the WHODAS

BACKGROUND

The eastern Democratic Republic of Congo (DRC) has experienced decades-long armed conflicts which have had a negative impact on population's health. Most research in public health explores measures that focus on a specific health problem rather than overall population health status. The aim of this study was to assess the health status of the population and its predictors in conflict settings of South Kivu province, using the World Health Organization Disability Assessment Schedule (WHODAS).

METHODS

Between May and June 2019, we conducted a community-based cross-sectional survey among 1440 adults in six health zones (HZ), classified according to their level of armed conflict intensity and chronicity in four types (accessible and stable, remote and stable, intermediate and unstable). The data were collected by a questionnaire including socio-demographic data and the WHODAS 2.0 tool with 12 items. The main variable of the study was the WHODAS summary score measuring individual's health status and synthesize in six domains of disability (household, cognitive, mobility, self-care, social and society). Univariate analysis, correlation and comparison tests as well as hierarchical multiple linear regression were performed.

RESULTS

The median WHODAS score in the accessible and stable (AS), remote and stable (RS), intermediate (I) and unstable (U) HZ was 6.3 (0-28.6); 25 (6.3-41.7); 22.9 (12.5-33.3) and 39.6 (22.9-54.2), respectively. Four of the six WHODAS domain scores (household, cognitive, mobility and society) were the most altered in the UHZs. The RSHZ and IHZ had statistically comparable global WHODAS scores. The stable HZs (accessible and remote) had statistically lower scores than the UHZ on all items. In regression analysis, the factors significantly associated with an overall poor health status (or higher WHODAS score) were advanced age, being woman, being membership of an association; being divorced, separated or widower and living in an unstable HZ.

CONCLUSIONS

Armed conflicts have a significantly negative impact on people's perceived health, particularly in crisis health zones. In this area, we must accentuate actions aiming to strengthen people's psychosocial well-being.

Effectiveness of a task-sharing collaborative care model for identification and management of depressive symptoms in patients with hypertension attending public sector primary care clinics in South Africa: pragmatic parallel cluster randomised controlled trial

BACKGROUND

We tested the real-world effectiveness of a collaborative task-sharing model on depressive symptom reduction in hypertensive Primary Health Care (PHC) patients in South Africa.

METHOD

A pragmatic parallel cluster randomised trial in 20 clinics in the Dr Kenneth Kaunda district, North West province. PHC clinics were stratified by sub-district and randomised in a 1:1 ratio. Control clinics received care as usual (CAU), involving referral to PHC doctors and/or mental health specialists. Intervention clinics received CAU plus enhanced mental health training and a lay counselling referral service. Participant inclusion criteria were ≥ 18 years old, Patient Health Questionnaire-9 (PHQ-9) score ≥ 9 and receiving hypertension medication. Primary superiority outcome was ≥ 50% reduction in PHQ-9 score at 6 months. Statistical analyses comprised mixed effects regression models and a non-inferiority analysis.

TRIAL REGISTRATION NUMBER

NCT02425124.

RESULTS

Between April 2015 and October 2015, 1043 participants were enrolled (504 intervention and 539 control); 82% were women; half were ≥ 55 years. At 6 and 12 months follow-up, 91% and 89% of participants were interviewed respectively. One control group participant committed suicide. There was no significant difference in the primary outcome between intervention (N=256/456) and control (N=232/492) groups (55.9% versus 50.9%; adjusted risk difference = -0.04 ([95% CI = -0.19; 0.11], p = 0.6). The difference in PHQ-9 scores was within the defined equivalence limits at 6 and 12 months for the non-inferiority analysis.

LIMITATIONS

The trial was limited by low exposure to depression treatment by trial participants and by observed co-intervention in control clinics CONCLUSIONS: Incorporating lay counselling services within collaborative care models does not produce superior nor inferior outcomes to models with specialist only counselling services.

A Multi-Dimensional Characterization of Aging and Wellbeing Among HIV-Positive Adults in Malawi

There is relatively little research on aging with HIV and wellbeing in sub-Saharan Africa. A cross-sectional survey was implemented in Malawi; eligible respondents were ≥ 30 years old and on ART for ≥ 2 years. Univariate and multiple regression analyses were stratified by age (younger adults: aged 30-49; older adults: aged ≥ 50) and gender. The median age was 51 years (total sample n = 134). Viral suppression was less common among older respondents (83.7% versus 93.0% among younger respondents) although not significant in adjusted models. Despite exhibiting worse physical and cognitive functioning (any physical functioning challenge: aOR 5.35, p = 0.02; cognitive functioning score difference: - 0.89 points, p = 0.04), older adults reported less interpersonal violence and fewer depressive symptoms (mild depression: aOR 0.23 p = 0.002; major depression: aOR 0.16, p = 0.004); in gender-stratified models, these relationships were significant only for females. More research is needed to disentangle the interplay between aging, gender and HIV in high-burden contexts and develop interventions to support comprehensive wellbeing in this population.

Self-Reported Disability in Persons With HIV-Related Neuropathy Is Mediated by Pain Interference and Depression

OBJECTIVE

The purpose of this study was to compare disability in people with HIV and peripheral neuropathy with those without neuropathy and explore how neuropathy and other relevant factors are associated with disability.

METHODS

In this cross-sectional study, participants completed the Brief pain inventory, Beck Depression Inventory II, World Health Organization Disability Assessment Schedule (WHODAS 2.0), and a health and demographic questionnaire. Additional data were extracted from the medical record. A raw score of ≥1 on the Subjective Peripheral Neuropathy Screen questions about lower extremity numbness or paresthesia was used to identify peripheral neuropathy. Predictors of disability (as determined by association with World Health Organization Disability Assessment Schedule 2.0 scores) were evaluated bivariately and in a multivariable model. Path modeling was used to identify a parsimonious model to elucidate the mediated effects of peripheral neuropathy on disability.

RESULTS

Participants with peripheral neuropathy had more depression symptoms, more pain (severity and interference), and higher disability scores compared with participants without neuropathy. The relationship between neuropathy and disability was mediated by pain interference and depression (standardized root mean residual = .056).

CONCLUSION

In this sample of people with HIV, those with lower extremity peripheral neuropathy reported more severe disability, worse pain, and more depression symptoms than those without neuropathy. The relationship between peripheral neuropathy and disability may be mediated though pain interference and depression.

IMPACT

Distal sensory polyneuropathy is a common comorbidity experienced by people living with HIV and frequently causes pain. This study can help providers direct care toward lessening disability experienced among people with HIV and peripheral neuropathy by targeting interventions for treatment of pain and depression.

LAY SUMMARY

People living with HIV may experience disabling painful neuropathy. Treatment for pain and depression may help reduce the disability associated with painful neuropathy.

The effect of HIV status on post-stroke outcomes in personal activities of daily living

Introduction

This study explored the impact of HIV on the functional recovery of personal activities of daily living of stroke survivors. This assisted in identifying possible implications for the rehabilitation of stroke survivors who are also HIV-positive.

Method

A quantitative, descriptive, longitudinal comparative research design was used to determine the change in personal activities of daily living scores of HIV-negative and HIV-positive stroke survivors from admission to 1 month after discharge. Data were collected at a rehabilitation unit using the South African Database Functional Measure.

Results

There was no difference in the rate and nature of functional recovery of personal activities of daily living between the two groups between admission and discharge. A difference was noticed during the period from admission to 1 month after discharge, during which the HIV-negative group continued to show improvement, while the HIV-positive group showed little improvement or a decline in personal activities of daily living scores.

Conclusions

While the rate and nature of functional recovery related to personal activities of daily living for HIV-positive and HIV-negative stroke survivors is similar during inpatient care, discharge planning for the HIV-positive group needs to consider the decline in personal activities of daily living functioning post discharge. Regular follow-ups and the inclusion of the stroke survivors in an outpatient treatment programme is recommended.

Predictors of receiving a diagnosis, referral and treatment of depression in people on antiretroviral therapy in South African primary care: a secondary analysis of data from a randomised trial

Objective

To describe the receipt of a diagnosis, referral and treatment for depression in people receiving antiretroviral therapy (ART), with depressive symptoms and attending primary care clinics in South Africa, and investigate factors associated with receiving these components of care.

Methods

This is a secondary analysis of data from a randomised controlled trial of an intervention intended to improve detection and treatment of depression in primary care patients receiving ART. In this analysis, we combined cross‐sectional and longitudinal data from the intervention and control arms. Using regression models and adjusting for intra‐cluster correlation of outcomes, we investigated associations between socioeconomic characteristics, depressive symptoms, stress, disability and stigma, and receipt of a diagnosis, referral and treatment for depression.

Results

Of 2002 participants enrolled, 18% reported a previous diagnosis of depression by a healthcare worker and 10% reported having received counselling from a specialist mental health worker. Diagnosis, referral and counselling during the follow‐up period were appropriately targeted, being independently more frequent in participants with higher enrolment scores for depressive symptoms, stress or disability. Participants with higher stigma scores at enrolment were independently less likely to receive counselling. Severe socio‐economic deprivation was common but was not associated with treatment.

Conclusion

While the receipt of a diagnosis, referral and treatment for depression were uncommon, they seemed to be appropriately targeted. Socio‐economic deprivation was not associated with treatment.

The multidimensional vulnerability of people with disability to HIV infection: Results from the handiSSR study in Bujumbura, Burundi

BACKGROUND

In resource-limited contexts, available data indicate that people with disability are disproportionally affected by the HIV epidemic. While disability resulting from chronic HIV infection has received some attention, few epidemiologic studies have examined the vulnerability of people with disability to HIV acquisition. The aims of the study were as follows: to estimate and compare HIV prevalence among people with and without disability living in Bujumbura, Burundi; to examine how the interaction among disability, gender and socioeconomic environment shapes vulnerability to HIV; and to identify potential pathways to higher HIV risk.

METHODS

In this cross-sectional population-based study, 623 persons with disability (302 with disability onset ≤10 years ["early disability"]) and 609 persons without disability matched for age, sex and location were randomly selected to be tested for HIV and to participate in an interview about their life history, their social environment and their knowledge of sexual health.

FINDINGS

A total of 68% of men and 75% of women with disability were affected by multidimensional poverty compared to 54% and 46% of their peers without disability (p<0.0001). Higher HIV prevalence was observed among women with disability (12.1% [8.2-16]) than among those without (3.8% [1.7-6], ORa 3.8, p<0.0001), while it was similar among men with disability and those without (p = 0·8). Women with disability were also at higher risk of sexual violence than were those without (ORa 2.7, p<0.0001). The vulnerability of women with early disability to HIV was higher among those who were socially isolated (HIV prevalence in this group: 19% [12-27]). In addition, education level and sexual violence mediated 53% of the association between early disability and HIV (p = 0.001).

INTERPRETATION

This study highlights how the intersection of disability, gender and social environment shapes vulnerability to HIV. It also shows that the vulnerability to HIV of women who grew up with a disability is mediated by sexual violence.

Reliability and Validity of the HIV Disability Questionnaire (HDQ) with Adults Living with HIV in the United States

OBJECTIVES

To assess measurement properties of the HIV Disability Questionnaire (HDQ) among adults with HIV in the United States.

METHODS

We administered the HDQ, World Health Organization Disability Assessment Schedule II (WHODAS 2.0), and a demographic questionnaire. For internal consistency reliability, we calculated Cronbach α and Kuder-Richardson-20 (KR-20) statistics for disability and episodic scores, respectively (≥0.80 acceptable). For test-retest reliability, we calculated intraclass correlation coefficients (>0.8 acceptable). For construct validity, we tested 15 a priori hypotheses assessing correlations between HDQ and WHODAS 2.0 scores.

RESULTS

Of the 128 participants, the majority were males (68%), median age 51 years, taking antiretroviral therapy (96%). Cronbach α ranged from 0.88 (social inclusion) to 0.93 (uncertainty). The KR-20 ranged from 0.86 (cognitive) to 0.96 (uncertainty). Intraclass correlation coefficients ranged from 0.88 (physical, cognitive, social inclusion) to 0.92 (mental-emotional). Of the 15 hypotheses, 13 (87%) were confirmed.

CONCLUSIONS

The HDQ demonstrates internal consistency reliability, test-retest reliability, and construct validity when administered to a sample of adults with HIV in the United States.

Functional Limitations and Disability in Persons Living with HIV in South Africa and United States: Similarities and Differences

Persons living with HIV (PLHIV) may experience disability. We compared disability among PLHIV in the United States and South Africa and investigated associations with health and demographic characteristics. Secondary analysis of cross-sectional data using medical records and questionnaires including the World Health Organization Disability Assessment Schedule (WHO-DAS) 2.0 12-item version (range: 0-36, with higher scores indicative of more severe disability). Between-country differences for the presence of disability were assessed with logistic regression and differences in severity using multiple regression. Eighty-six percent of US participants reported disability, compared to 51.3% in South Africa. The mean WHO-DAS score was higher in the United States (12.09 ± 6.96) compared to South Africa (8.3 ± 6.27). Participants with muscle pain, depression, or more years since HIV diagnosis were more likely to report disability. Being female or depressed was associated with more severity. Being adherent to anti-retroviral therapy (ART) and employed were associated with less severity. Because muscle pain and depression were predictive factors for disability, treatment of those problems may help mitigate disability in PLHIV.

Participants' Reflections on a Home-Based Rehabilitation Intervention for People Living With HIV in KwaZulu-Natal, South Africa

Rehabilitation for people living with HIV (PLWH) can improve physical function and reduce activity limitations common in this population. Institution-based rehabilitation interventions are often difficult to access, particularly in resource-constrained communities. Our study used semistructured interviews to describe the experiences of eight PLWH involved in a novel home-based rehabilitation intervention in KwaZulu-Natal, South Africa. Participants reported a number of physical and mental benefits related to their involvement in this 4-month intervention. They further described a number of extrinsic and intrinsic facilitators that enabled them to continue to exercise and, in some cases, to return to work, 1 year after the intervention. These facilitators helped them face various life challenges, which included stigma related to their HIV status and disability and continued poverty and hunger. The findings of our study support calls for alternative accessible rehabilitation options for PLWH in resource-constrained communities.

HIV Status and Antiretroviral Therapy as Predictors of Disability among Older South Africans: Overall Association and Moderation by Body Mass Index

Objectives: Among older people living with HIV (PLWH) and comparable individuals without HIV, we evaluated whether associations of HIV and antiretroviral therapy (ART) with disability depend on body mass index (BMI). Methods: We analyzed 4552 participants in the "Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa." (HAALSI) We compared prevalence of disability (≥1 impairment in basic activities of daily living) by HIV status, ART use, and BMI category, adjusting for age, sex, education, father's occupation, country of origin, lifetime alcohol use, and primary health-care utilization. Results: Among PLWH, those underweight had 9.8% points (95% confidence interval (CI): 1.2 to 18.4) higher prevalence of disability than those with normal BMI. Among ART users, those underweight had 11.9% points (95% CI: 2.2 to 21.6) higher prevalence of disability than those with normal BMI. Conclusions: We found no evidence that weight improvement associated with ART use is likely to increase disability.

Social and Structural Determinants of Household Support for ART Adherence in Low- and Middle-Income Countries: A Systematic Review

Adherence to HIV antiretroviral therapy (ART) is a crucial factor in health outcomes for people living with HIV (PLWH). Interventions to support ART adherence are increasingly focused on the household as a source of social support. This review aims to examine the social and structural determinants of support for ART adherence within households and families in low- and middle-income countries (LMICs). The review methodology followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Seven databases were searched for peer-reviewed literature. The terms searched thematically covered (1) ART adherence, (2) household and family and (3) support and care. Thirty-three studies conducted in 15 LMICs were selected and a mixed methods synthesis was undertaken. Social and structural determinants affected the type, quality and amount of support for PLWH of all ages, which affected PLWH's ART adherence. Gender norms affected the type of support that household members give to PLWH. Education moderated household support for ART adherence through literacy and language skills. Cultural context, religious beliefs, and social norms reinforced or undermined household support for ART adherence. Stigma affected disclosure, generated secrecy around giving medication and impeded access to support from the community. Supporting PLWH exacerbated economic hardship for household members. Health system dysfunction negatively impacted trust and communication between household members and health professionals. Intersecting social and structural determinants particularly affected the care given by household members who were older, female, with little education and low socioeconomic status. Household members were able to overcome some of these barriers when they received support themselves. Household interventions to support PLWH's ART adherence should take structural factors into account to have maximum impact.

Research priorities for rehabilitation and aging with HIV: a framework from the Canada-International HIV and Rehabilitation Research Collaborative (CIHRRC)

BACKGROUND

People living with HIV are living longer, and can experience physical, mental and social health challenges associated with aging and multimorbidity. Rehabilitation is well positioned to address disability and maximize healthy aging. An international collaborative network, called the Canada-International HIV and Rehabilitation Research Collaborative (CIHRRC), works to guide this emerging field. In this article, we report findings from CIHRRC's aim to identify emerging research priorities in HIV, aging and rehabilitation from the perspectives of people living with HIV, clinicians, researchers, representatives from community organizations and policy stakeholders.

METHODS

We conducted a multi-stakeholder multi-method international consultation with people living with HIV, researchers, clinicians and representatives of community-based organizations to identify research priorities in HIV, aging and rehabilitation. Stakeholders identified research priorities during a one-day International Forum comprised of presentations and facilitated discussion. We collated and analyzed data using content analytical techniques, resulting in a framework of research priorities.

RESULTS

Sixty-nine stakeholders from countries including Canada (n = 62; 90%), the United Kingdom (n = 5; 7%), United States (n = 1; 1%) and Australia (n = 1; 1%) attended the International Forum on HIV, Aging and Rehabilitation Research. Stakeholders represented community-based organizations (n = 20; 29%), academic institutions (n = 18; 26%), community or institutional healthcare organizations (n = 11; 16%), research or knowledge production organizations (n = 10; 14%), and organizations representing government or industry (n = 10; 14%). The Framework of Research Priorities in HIV, Aging and Rehabilitation includes seven research priorities: (1) nature, extent and impact of disability, concurrent health conditions and chronic inflammation with HIV; (2) prevalence, severity and impact of frailty; (3) community and social participation aging with HIV; (4) strategies for chronic disease management and healthy aging with HIV; (5) facilitators and barriers to access and engagement in, rehabilitation; (6) effectiveness of rehabilitation interventions for healthy aging with HIV; and (7) advancing development and use of patient reported outcome measures in HIV and aging. The Framework highlights methodological considerations to approach the priorities and the importance of knowledge translation and exchange to apply research knowledge into practice, programs and policy.

CONCLUSIONS

These priorities offer a foundation for collaboration among international and multidisciplinary teams to advance the field of HIV, aging and rehabilitation in order to promote healthy aging with HIV.

Trends in health and disability in Botswana. An analysis of the global burden of disease study

Purpose: Globally, years of life lost are declining, while years lived with disability are increasing. In high socio-demographic index countries, this trend has been attributed to an overall ageing population and rehabilitation services have begun to adjust to this change. In low- and middle-income countries, this trend is less well understood. Hence, the WHO's 'Rehabilitation 2030 Call for Action' and 'Rehabilitation in Health Systems Guide' call for better assessment of the situation. In order to understand trends and causes in middle income countries such as Botswana, we examine the change over time in causes and number of years lived with disability and years of life lost.Methods: We conducted a secondary analysis of the Global Burden of Disease 2017 data, exploring the change over time in Disability Adjusted Life Years per 100 000 people over the period 1990-2016. The descriptive analysis focuses on the contribution of years lived with disability towards the burden of disease within Botswana compared with the world, sub-Saharan Africa, and high-income countries.Results: Our results show that Botswana's top causes of years of life lost are HIV and other sexually transmitted infections, cardiovascular diseases, maternal and neonatal disorders, respiratory infections and tuberculosis, and neoplasms. Years lived with disability have increased over time, which is driven by mental disorders, HIV and other sexually transmitted infections, musculoskeletal disorders, neurological disorders, and skin and subcutaneous diseases.Conclusions: Botswana needs better data to prepare its emerging health systems to accommodate the increased need for disability support and rehabilitation services caused by communicable and non-communicable diseases.Implications for RehabilitationBotswana has an increase in disability prevalence over time that requires the development of disability and rehabilitation services.The greatest contributors towards disability adjusted life years in Botswana are currently mental disorders (13.7%), HIV and other sexual transmitted diseases, (13.0%), musculoskeletal disorders (9.9%), neurological disorders (8.0%), and sense organ diseases (6.2%).This requires strengthen of services such as mental health interventions, physiotherapy, optometry and audiology as well as linkages from major disease clusters such as HIV to rehabilitation services.

Fall History and Associated Factors Among Adults Living With HIV-1 in the Cape Winelands, South Africa: An Exploratory Investigation

Background

People with HIV-1 (PWH) exhibit a high fall incidence and increased fracture risk. As little is known about fall frequency and associated factors in PWH residing in lower-middle-income countries (LMIC), we investigated fall frequency, bone quality, and factors associated with fall history in a South African cohort.

Methods

Fifty PWH without obvious predisposing factors for mobility impairments attending 2 public primary care clinics in the Western Cape region participated. Demographic, clinical, and physical performance data were collected. Falls were assessed retrospectively over 12 months. Mobility and balance were evaluated using a physical performance battery. Bone mineral density was screened using quantitative ultrasound (QUS). Associations between variables and falls grouping were analyzed using chi-square tests, t tests, and Mann-Whitney U tests, and effect sizes (ES) were calculated.

Results

Thirty-four percent of PWH (median age, 36.6 years) reported falling during the past year, and 41.2% of fallers reported multiple falls. Fallers had more mobility problems (P = .013), higher fear of falling (P = .007), higher fracture history (P = .003), worse balance performance (P < .001), higher proportions of detectable viral loads (P = .021), and poorer bone quality (P = .040). Differences were of medium to large ES.

Conclusions

This exploratory study is the first to show that relatively young South African PWH without obvious predisposing factors for gait and balance impairments experience falls. The observed fall-associated factors warrant further research using larger samples and longitudinal designs to ascertain fall predictors within this population.

Children living with HIV-related disabilities in a resource-poor community in South Africa: caregiver perceptions of caring and rehabilitation

The care offered to children living with HIV (CLHIV) experiencing HIV-related disability is often challenged by caregiver illness, poverty and poor support structures in and around communities. Since caregiver needs directly influences the care offered to CLHIV this paper aimed to explore the experiences of the caregivers of CLHIV in order to inform an appropriate rehabilitation model in South Africa. A qualitative enquiry using in-depth interviews with 14 caregivers (one male and thirteen females) of CLHIV experiencing disability in a peri-urban setting was conducted. Data were analysed using thematic analysis. Four themes emerged from the interviews: understanding of HIV-related disability and rehabilitation, challengers to care and well-being, enablers to care; and perceived needs of caregivers. The study revealed that caregiver burden is influenced by the availability of resources and social support services. Financial constraints, poor access to rehabilitation and reduced support networks challenged the care offered to CLHIV. The perceived needs of the caregivers in this study included appeals for improved social security, housing, accessible rehabilitation and education. Changes in government policy guiding social support, employment, education and rehabilitation interventions are needed to improve the availability of resources, education, health and well-being of CLHIV and their caregiver's in South Africa.

Perspectives on ART adherence among Zambian adults living with HIV: insights raised using HIV-related disability frameworks

Anti-retroviral treatment (ART) has improved the survival of people living with HIV in Africa. Living with chronic HIV comes with new health and functional challenges and the need to manage ART adherence. The Sepo Study applied disability frameworks to better understand living with chronic HIV while using ART. The study followed 35 people (18 women, 17 men) living with HIV and on ART 6 months or longer in private and public health facilities in Lusaka, Zambia over 18-months (2012-2015). A total of 99 in-depth interviews were conducted. Conventional content analysis and NVIVOv10 were applied to analyse the data. Participants were adhering to ART at the times of the interviews and therefore less likely to report major challenges with adherence. Three main themes emerged from the data related to adherence. Firstly, ART was regarded as "giving life", which underscored adherence. Secondly, all participants described strategies for to managehealth and functional limitations, which they attributed as side-effects or chronicity. Thirdly, participants described experiences of uncertainty, including the efficacy of new regimens, potential loss of functioning, risk of new health problems, and death. Long-term ART managment in Africa needs to integrate rehabilitation approaches to address functional limitations, uncertainties, strengthen and support for adherence.

The World Health Organization Disability Assessment Schedule 2 (WHODAS 2.0): remarks on the need to revise the WHODAS

Functioning and disability are concepts in increasing use in clinical settings and in public health. From the public health perspective, the use of functioning as a third health indicator could show more than the frequency of a disease and its death rates, offering information on how the population performs its activities and participation. Clinically, the functioning assessment can provide information for patient-centered health care and specific clinical interventions according to their functioning profile. WHODAS 2.0 is a generic tool to assess health and functioning according to the ICF functioning model. It is an alternative to assess functioning in a less time-consuming way, whereas the duration of the application is one of the main ICF critiques. This paper aims to present some of WHODAS 2.0 inconsistencies and weaknesses as well as strategies to cope with them. In this paper, we present some weaknesses related to the WHODAS layout; wording and scoring process. Some suggestions for strategies to correct these weaknesses are presented, as well.

Factors Affecting Psychological Distress among People Living with HIV/AIDS at Selected Hospitals of North Shewa Zone, Amhara Region, Ethiopia

Background

The new advances for the treatment of HIV infection using Highly Active Antiretroviral Therapy (HAART) have dramatically improved disease prognosis. However, they are living longer with a chronic condition that increases the risk for psychiatric and psychosocial problems. Various studies have linked HIV/AIDS with a number of psychological problems, depression being the most common. Moreover, studies have found that chronically ill people are at increased risk of psychological problems. Thus, this study aimed at assessing the level of psychological distress and its associated factors among people living with HIV/AIDS in selected Hospitals of North Sowa Zone of Amhara region, Ethiopia, 2017.

Method

Institution based cross-sectional study design with systematic random sampling method was used. Data was collected by structured interviewer-based Amharic version questionnaire. A total of 422 people living with HIV/AIDS were involved in the study from 1 to 30 May 2017. Data analysis was done with the help of a computer program (SPSS version 16.0). Binary logistic regression analysis was used for bivariate and multivariate analysis. The strength of the association was presented by odds ratio with a 95% confidence interval.

Result

The prevalence of psychological distress was 7.8% (95% CI: 5.25%, 10.39%). Being female (AOR = 3.02; 95% CI: 1.16, 7.82), illiterates (AOR = 3.91; 95% CI: 1.31, 6.45), participants who currently use alcohol (AOR = 2.70; 95% CI: 1.23, 5.88), respondents whose CD4 count is less than 500 cells/μl (AOR = 2.28; 95% CI: 1.02, 5.11), and participants who are considered stigmatized (AOR = 2.41; 95% CI: 1.11, 5.22) were positively associated with psychological distress.

Conclusion

The prevalence of psychological distress was low as compared to other studies conducted in Ethiopia. This may affect the quality of life of people living with HIV/AIDS and their families. Being female, illiteracy, alcohol use, and having lower CD4 count and perceived stigma increased the odds of psychological distress. Thus, concerned stakeholders should collaborate on the integration of HIV/AIDs treatment and mental health services.

Longitudinal depressive and anxiety symptoms of adult injury patients in Kenya and their risk factors

Background: Injuries account for a significant proportion of the health and economic burden for populations in low- and middle-income countries. However, little is known about psychological distress trajectories amongst injury survivors in low- and middle-income countries.Methods: Adult injury patients (n = 644) admitted to Kenyatta National Hospital in Nairobi, Kenya, were enrolled and interviewed in the hospital, and at 1, 2-3, and 4-7 months after hospital discharge through phone to assess depressive and anxiety symptoms and level of disability. Growth mixture modeling was applied to identify latent trajectories of depressive and anxiety symptoms.Results: Elevated depressive and moderate-level anxiety symptoms (13%) and low depressive and anxiety symptoms (87%) trajectories were found between hospitalization and up to seven months after hospital discharge. Being female, prior trauma experience, longer hospitalization, worse self-rated health status while in the hospital, and lack of monetary assistance during hospitalization were associated with the elevated symptoms trajectory. The higher symptoms trajectory associated with higher disability levels after hospital discharge and significantly lower proportion of resuming daily activities and work.Conclusion: The persistence of elevated depressive symptoms and associated reduced functioning several months after physical injury underscores the importance of identifying populations at risk for preventive and early interventions.Implications for RehabilitationHealth providers following up with injury survivors should screen for depressive and anxiety symptomsSpecial attention to women and people with a potential traumatic exposure historyIncorporation of evidence-based culturally adapted psychosocial interventions in rehabilitation and outpatient clinics.

The missing link: exploring the intersection of gender, capabilities, and depressive symptoms in the context of chronic HIV

Depressive symptoms occur frequently among people living with HIV, especially women. These symptoms are associated with human, social, financial, and physical/natural capabilities and life stressors that differ between women and men. However, the link between depressive symptoms and functional limitations/disability is seldom discussed in the context of HIV, especially for gender-specific relationships. A cross-sectional survey of 1042 people living with HIV and using long-term antiretroviral therapy (ART) in South Africa was conducted from June to August 2014 to investigate the associations of disability, human, social, physical/natural, and financial capabilities, health, and adherence to ART, including possible gender-specific factors. Socio-demographic information, capabilities, health indicators, functional limitations/disability, and depressive symptoms (CES-D 10) were measured. We applied descriptive and bivariate statistics and multiple regression. Overall, 26% of people presented with depressive symptoms. Greater functional limitations and health symptoms and lower food security were strongly associated with depressive symptoms, while associations with financial capital and body mass index were gender-specific. The results call for the improvement of comprehensive care, including gender-sensitive mental health interventions. The results further indicate that functional limitations/disability needs to be considered, along with linking rehabilitation and livelihood programs with comprehensive HIV-care, in particular for those who experience depressive symptoms.

Evaluation of a collaborative care model for integrated primary care of common mental disorders comorbid with chronic conditions in South Africa

BACKGROUND

The rise in multimorbid chronic conditions in South Africa, large treatment gap for common mental disorders (CMDs) and shortage of mental health specialists demands a task sharing approach to chronic disease management that includes treatment for co-existing CMDs to improve health outcomes. The aim of this study was thus to evaluate a task shared integrated collaborative care package of care for chronic patients with co-existing depressive and alcohol use disorder (AUD) symptoms.

METHODS

The complex intervention strengthened capacity of primary care nurse practitioners to identify, diagnose and review symptoms of CMDs among chronic care patients; and implemented a stepped up referral system, that included clinic-based psychosocial lay counsellors, doctors and mental health specialists. Under real world conditions, in four PHC facilities, a repeat cross-sectional Facility Detection Survey (FDS) assessed changes in capacity of nurses to correctly detect CMDs in 1310 patients before implementation and 1246 patients following implementation of the intervention at 12 months; and a non-randomly assigned comparison group cohort study comprising 373 screen positive patients with depressive symptoms using the Patient Health Questionnaire-9 (PHQ9) at baseline, evaluated responses of patients correctly identified and referred for treatment (intervention arm) or not identified and referred (control arm) at three and 12 months.

RESULTS

The FDS showed a significant increase in the identification of depression and AUD from pre-implementation to 12-month post-implementation. Depression: (5.8 to 16.4%) 95% CI [2.9, 19.1]); AUD: (0 to 13.8%) 95% CI [0.6-24.9]. In the comparison group cohort study, patients with depressive symptoms having more than a 50% reduction in PHQ-9 scores were greater in the treatment group (n = 69, 55.2%) compared to the comparison group (n = 49, 23.4%) at 3 months (RR = 2.10, p < 0.001); and 12 months follow-up (intervention: n = 57, 47.9%; comparison: n = 60, 30.8%; RR = 1.52, p = 0.006). Remission (PHQ-9 ≤ 5) was greater in the intervention group (n = 32, 26.9%) than comparison group (n = 33, 16.9%) at 12 months (RR = 1.72, p = 0.016).

CONCLUSION

A task shared collaborative stepped care model can improve detection of CMDs and reduce depressive symptoms among patients with chronic conditions under real world conditions.

Epidemiology of depressive disorders in people living with HIV in Africa: a systematic review and meta-analysis: Burden of depression in HIV in Africa

OBJECTIVE

The burden of HIV infection is higher in Africa where 70% of people living with HIV (PLHIV) resides. Since depression can negatively impact the course of HIV infection, it is therefore important to accurately estimate its burden among PLHIV in the continent.

METHODS

We searched multiple databases to identify articles published between January 2000 and February 2018, reporting the prevalence of (major) depressive disorders in PLHIV residing in Africa. We used a random-effects meta-analysis model to pool studies.

RESULTS

Overall, 118 studies (60,476 participants, 19 countries) were included. There was no publication bias. The overall prevalence estimates of depressive disorders and probable major depressive disorders were 36.5% (95% CI 32.3-41.0; 101 studies) and 14.9% (12.1-17.9; 55 studies) respectively. The heterogeneity of the overall prevalence of depressive disorders was significantly explained by screening tool used, period (higher prevalence in recent studies) and distribution in sub-regions. The study setting, site, CD4 cell counts, age, sex, proportion of people with undetectable viral load were not sources of heterogeneity.

CONCLUSIONS

This study shows that more than one third of PLHIV face depressive disorders and half of them having major form, with heterogeneous distribution in the continent. As such, depressive disorders deserve more attention from HIV healthcare providers for improved detection and overall proper management.

Physical activity and quality of life in people living with HIV

As life expectancy in people living with HIV (PWH) has increased, the focus of management has shifted to preventing and treating chronic illnesses. Regular physical activity (PA) has been shown to reduce the impact of HIV on both physical and mental health. Our objectives were to assess the PA levels of PWH compared to HIV negative controls; investigate factors associated with PA; and determine the effect of PA levels on quality of life and mental well-being. We recruited 110 PWH and 110 HIV negative controls in this cross-sectional, single-centre study. Physical activity, quality of life and mental well-being were assessed using the rapid assessment of physical activity tool, EQ-5D-5L Questionnaire, and the Warwick-Edinburgh Mental Well-being Score. Binary logistic regression and multiple linear regression were used to identify factors associated with PA levels and mental well-being scores respectively. PWH were less likely to meet the WHO-recommended PA requirements compared to controls (50.0% vs. 64.5%; p = 0.041) and had significantly lower mental wellbeing and quality of life scores. Additionally, in PWH higher PA levels were associated with improved self-rated quality of life scores (p = 0.027). Our results suggest that targeted exercise programmes could have a beneficial effect on health status in PWH.

Trauma Exposure, Posttraumatic Stress Disorder Symptoms Trajectory, and Disability Level Among Hospitalized Injury Survivors in Kenya

Potentially traumatic events (PTEs) have been consistently associated with posttraumatic stress disorder (PTSD). However, the extent of association and attribution to subsequent disability has varied, with limited studies conducted in urban low-income contexts. This longitudinal study estimated the trajectory of PTSD symptoms up to 7 months after hospitalization and the associated disability level among adult patients who had been hospitalized due to injury. Adult injury patients (N = 476) admitted to Kenyatta National Hospital in Nairobi, Kenya, were interviewed in person in the hospital, and via phone at 1, 2-3, and 4-7 months after hospital discharge. Using latent growth curve modeling, two trajectories of PTSD symptoms emerged: (a) persistently elevated PTSD symptoms (9.2%), and (b) low PTSD symptoms (90.8%). Number of PTEs experienced remained moderately associated with the elevated trajectory after controlling for in-hospital depressive symptoms. Having previously witnessed killings or serious injuries, AOR = 2.32, 95% CI [1.07, 5.05]; being female, AOR = 4.74, 95% CI [4.53, 4.96]; elevated depressive symptoms during hospitalization, AOR = 2.96, 95% CI [1.28, 6.83]; and having no household savings/assets, AOR = 1.28, 95% CI [1.13, 1.44], were associated with the elevated PTSD symptoms trajectory class after controlling for other risk factors. Latent membership in the elevated PTSD trajectory was associated with a significantly higher level of disability several months after hospital discharge, p < .001, after controlling for injury and demographic characteristics. These results underline the associations among in-hospital depressive symptoms, witnessing atrocities, and poverty, and an elevated PTSD symptoms trajectory.

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.

Disability and health outcomes - from a cohort of people on long-term anti-retroviral therapy

Human-immunodeficiency virus (HIV)/Acquired immunodeficiency Syndrome (AIDS) remains a major health problem in South Africa - even after two decades since the introduction of antiretroviral therapy (ART). Long-term survival with HIV is associated with new health-related issues and a risk of functional limitation/disability. The aim of this study was to assess functional limitation associated with HIV/AIDS among people living with HIV (PLHIV) in South Africa. This study is a cross-sectional survey using a cohort in an urban area in Gauteng province, South Africa. Data were collected using questionnaires through an interview process. The information collected included aspects such as demographics, livelihood, the state of mental and physical health, adherence and disability. A total of 1044 participants with an average age of 42 ± 12 years were included in the study, with 51.9% of the participants reporting functional limitations (WHODAS ≥ 2). These were reported mainly in the domains of participation (40.2%) and mobility (38.7%). In addition, adherence to ART, symptoms of poor physical health and depression were strongly associated with their functional limitations/disability. HIV as a chronic disease is associated with functional limitations that are not adequately addressed and pose a risk of long-term disability and negative adherence outcomes. Therefore, wellness for PLHIV/AIDS needs to include interventions that can prevent and manage disability.

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.

"Even the fowl has feelings": access to HIV information and services among persons with disabilities in Ghana, Uganda, and Zambia

Background: Persons with disabilities have often been overlooked in the context of HIV and AIDS risk prevention and service provision. This paper explores access to and use of HIV information and services among persons with disabilities.Methods: We conducted a multi-country qualitative research study at urban and rural sites in Uganda, Zambia, and Ghana: three countries selected to exemplify different stages of the HIV response to persons with disabilities. We conducted key informant interviews with government officials and service providers, and focus group discussions with persons with disabilities and caregivers. Research methods were designed to promote active, meaningful participation from persons with disabilities, under the guidance of local stakeholder advisors.Results: Persons with disabilities emphatically challenged the common assumption that persons with disabilities are not sexually active, pointing out that this assumption denies their rights and - by denying their circumstances - leaves them vulnerable to abuse. Among persons with disabilities, knowledge about HIV was limited and attitudes towards HIV services were frequently based upon misinformation and stigmatising cultural beliefs; associated with illiteracy especially in rural areas, and rendering people with intellectual and developmental disability especially vulnerable. Multiple overlapping layers of stigma towards persons with disabilities (including internalised self-stigma and stigma associated with gender and abuse) have compounded each other to contribute to social isolation and impediments to accessing HIV information and services. Participants suggested approaches to HIV education outreach that emphasise the importance of sharing responsibility, promoting peer leadership, and increasing the active, visible participation of persons with disabilities in intervention activities, in order to make sure that accurate information reflecting the vulnerabilities of persons with disabilities is accessible to people of all levels of education. Fundamental change to improve the skills and attitudes of healthcare providers and raise their sensitivity towards persons with disabilities (including recognising multiple layers of stigma) will be critical to the ability of HIV service organisations to implement programs that are accessible to and inclusive of persons with disabilities.Discussion: We suggest practical steps towards improving HIV service accessibility and utilisation for persons with disabilities, particularly emphasising the power of community responsibility and support; including acknowledging compounded stigma, addressing attitudinal barriers, promoting participatory responses, building political will and generating high-quality evidence to drive the continuing response.Conclusions: HIV service providers and rehabilitation professionals alike must recognise the two-way relationship between HIV and disability, and their multiple overlapping vulnerabilities and stigmas. Persons with disabilities demand recognition through practical steps to improve HIV service accessibility and utilisation in a manner that recognises their vulnerability and facilitates retention in care and adherence to treatment. In order to promote lasting change, interventions must look beyond the service delivery context and take into account the living circumstances of individuals and communities affected by HIV and disability. Implications for RehabilitationPersons with disabilities are vulnerable to HIV infection but have historically been excluded from HIV and AIDS services, including prevention education, testing, treatment, care and support. Fundamental change is needed to address practical and attitudinal barriers to access, including provider training.Rehabilitation professionals and HIV service providers alike must acknowledge the two-way relationship between HIV and disability: people with disability are vulnerable to HIV infection; people with HIV are increasingly becoming disabled.Peer participation by persons with disabilities in the design and implementation of HIV services is crucial to increasing accessibility.Addressing political will (through the National Strategic Plan for HIV) is crucial to ensuring long-term sustainable change in recognizing and responding to the heightened vulnerability of people with disability to HIV.

A Systematic Review of Access to General Healthcare Services for People with Disabilities in Low and Middle Income Countries

Background: A systematic review was undertaken to explore access to general healthcare services for people with disabilities in low and middle-income countries (LMICs). Methods: Six electronic databases were searched in February 2017. Studies comparing access to general healthcare services by people with disabilities to those without disabilities from LMICs were included. Eligible measures of healthcare access included: utilisation, coverage, adherence, expenditure, and quality. Studies measuring disability using self-reported or clinical assessments were eligible. Title, abstract and full-text screening and data extraction was undertaken by the two authors. Results: Searches returned 13,048 studies, of which 50 studies were eligible. Studies were predominantly conducted in sub-Saharan Africa (30%), Latin America (24%), and East Asia/Pacific (12%). 74% of studies used cross-sectional designs and the remaining used case-control designs. There was evidence that utilisation of healthcare services was higher for people with disabilities, and healthcare expenditure was higher. There were less consistent differences between people with and without disabilities in other access measures. However, the wide variation in type and measurement of disability, and access outcomes, made comparisons across studies difficult. Conclusions: Developing common metrics for measuring disability and healthcare access will improve the availability of high quality, comparable data, so that healthcare access for people with disabilities can be monitored and improved.

Designing robot-assisted neurorehabilitation strategies for people with both HIV and stroke

There is increasing evidence that HIV is an independent risk factor for stroke, resulting in an emerging population of people living with both HIV and stroke all over the world. However, neurorehabilitation strategies for the HIV-stroke population are distinctly lacking, which poses an enormous global health challenge. In order to address this gap, a better understanding of the HIV-stroke population is needed, as well as potential approaches to design effective neurorehabilitation strategies for this population. This review goes into the mechanisms, manifestations, and treatment options of neurologic injury in stroke and HIV, the additional challenges posed by the HIV-stroke population, and rehabilitation engineering approaches for both high and low resource areas. The aim of this review is to connect the underlying neurologic properties in both HIV and stroke to rehabilitation engineering. It reviews what is currently known about the association between HIV and stroke and gaps in current treatment strategies for the HIV-stroke population. We highlight relevant current areas of research that can help advance neurorehabilitation strategies specifically for the HIV-stroke population. We then explore how robot-assisted rehabilitation combined with community-based rehabilitation could be used as a potential approach to meet the challenges posed by the HIV-stroke population. We include some of our own work exploring a community-based robotic rehabilitation exercise system. The most relevant strategies will be ones that not only take into account the individual status of the patient but also the cultural and economic considerations of their respective environment.

Investigating the interaction between human immunodeficiency virus, nutrition, and disability: A cross-sectional observational study

Background

The average lifespan of people with human immunodeficiency virus (HIV) has increased because of the enhanced access to anti-retroviral treatment. This increased longevity has led to a heightened focus on the comorbidities which may arise, allowing a clearer understanding of the contextual, personal, psychological and functional problems and their interrelations. Disability (functional limitations) and insufficient nutritional intake may interact cyclically with HIV and/or acquired immunodeficiency syndrome (AIDS); however, no research to date has investigated this interaction.

Aims

The objective of this article was to report on the nutritional outcomes using albumin and body mass index outcomes as a subset of a larger study among adults living with HIV and/or AIDS.

Setting

This study was conducted at a large HIV clinic based in an urban area in Johannesburg, South Africa, which provides HIV treatment and support to over 6000 persons with HIV and TB. This clinic is part of a large public health regional hospital where extensive HIV research is undertaken.

Methods

This study was a cross-sectional observational study. The sample composed of 278 participants between 18 and 65 years of age and had been on highly active antiretroviral therapy (HAART) for more than six months. Statistical analyses were performed using the Statistical Package for the Social Sciences.

Results

The results indicated that albumin level had significant inverse associations with functional limitations and physical health symptoms. Women were significantly more likely to have lower nutritional levels. A logistic regression analysis suggested that gender and physical health symptoms were the primary predictors of albumin levels.

Conclusion

The findings presented in this article can be applied to HIV and/or AIDS treatment programmes, such as HAART. It re-emphasises the importance of providing individuals on anti-retroviral therapy with affordable and adequate nutrition, education on the importance of nutritional intake and the benefits of potentially adopting supplement programmes. As females seem to be more adversely affected by low nutritional levels, with the findings showing an increased likelihood of developing physical health symptoms, focus also needs to be given to cultural or social factors that impact nutritional intake in women.

Collaborative care for the detection and management of depression among adults with hypertension in South Africa: study protocol for the PRIME-SA randomised controlled trial

Background

The high co-morbidity of mental disorders, particularly depression, with non-communicable diseases (NCDs) such as cardiovascular disease (CVD), is concerning given the rising burden of NCDs globally, and the role depression plays in confounding prevention and treatment of NCDs. The objective of this randomised control trial (RCT) is to determine the real-world effectiveness of strengthened depression identification and management on depression outcomes in hypertensive patients attending primary health care (PHC) facilities in South Africa (SA).

Methods/design

The study design is a pragmatic, two-arm, parallel-cluster RCT, the unit of randomisation being the clinics, with outcomes being measured for individual participants. The 20 largest eligible clinics from one district in the North West Province are enrolled in the trial. Equal numbers of hypertensive patients (n = 50) identified as having depression using the Patient Health Questionnaire (PHQ-9) are enrolled from each clinic, making up a total of 1000 participants with 500 in each arm. The nurse clinicians in the control facilities receive the standard training in Primary Care 101 (PC101), a clinical decision support tool for integrated chronic care that includes guidelines for hypertension and depression care. Referral pathways available include referrals to PHC physicians, clinical or counselling psychologists and outpatient psychiatric and psychological services. In the intervention clinics, this training is supplemented with strengthened training in the depression components of PC101 as well as training in clinical communication skills for nurse-led chronic care. Referral pathways are strengthened through the introduction of a facility-based behavioural health counsellor, trained to provide structured manualised counselling for depression and adherence counselling for all chronic conditions. The primary outcome is defined as at least 50% reduction in PHQ-9 score measured at 6 months.

Discussion

This trial should provide evidence of the real world effectiveness of strengtheneddepression identification and collaborative management on health outcomes of hypertensive patients withcomorbid depression attending PHC facilities in South Africa.

Where and how does physical therapy fit? Integrating physical therapy into interprofessional HIV care

Purpose: To investigate the role of physical therapy in HIV care from the perspective of people living with HIV and health care professionals with expertise in HIV care. Methods: We conducted a qualitative descriptive study using semistructured interviews (with health care professionals) and focus groups (with people living with HIV). We purposively sampled health care professionals and recruited people living with HIV in collaboration with an HIV-specialty hospital. We asked participants about their knowledge of and experiences with physical therapy, and perceptions of the physical therapy role in interprofessional HIV care. We analyzed data using content analytical techniques. Results: Thirteen people living with HIV and 12 health care professionals conceptualized physical therapy as positively influencing independence and social participation, and as a valuable ally in interprofessional collaboration. The Framework of Physical Therapy Role in HIV Care consists of two components: (1) multidimensional and client-centered roles of physical therapy addressing physical, psychological and social health domains; and (2) contextual factors important to consider for the role of physical therapy: aging, episodic nature of HIV, multimorbidity, competing priorities, continuity of care, stigma, resource security and social isolation. The interaction between contextual factors and health domains can influence the role of physical therapy. Conclusion: The role of physical therapy in HIV is multidimensional and client-centered. This Framework can be used by rehabilitation professionals working with people living with HIV. Implications for Rehabilitation Participants living with HIV in this study experienced physical therapy as a means of addressing rehabilitation goals that positively influenced physical health and social participation. The role of physical therapy in HIV care is multidimensional and client-centered and can address health challenges in physical, social and psychological health domains. The presence and interaction of contextual factors including aging, episodic nature of HIV, multimorbidity, competing priorities, continuity of care, stigma, resource security and social isolation are important for clinicians to consider in order to optimize healthcare for people living with HIV. The Framework describing the role of physical therapy in HIV care can be used by rehabilitation professionals to help inform their approach for providing client-centered HIV care.

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.
