The long road to universal antiretroviral treatment coverage in South Africa

Understanding the persistence of vertical (stand-alone) HIV clinics in the health system in Uganda: a qualitative synthesis of patient and provider perspectives

Background

Although there is mounting evidence and policy guidance urging the integration of HIV services into general health systems in countries with a high HIV burden, vertical (stand-alone) HIV clinics are still common in Uganda. We sought to describe the specific contexts underpinning the endurance of vertical HIV clinics in Uganda.

Methods

A qualitative research design was adopted. Semi-structured interviews were conducted with the heads of HIV clinics, clinicians and facility in-charges (n = 78), coupled with eight focus group discussions (64 participants) with patients from 16 health facilities purposively selected, from a nationally-representative sample of 195 health facilities across Uganda, because they run stand-alone HIV clinics. Data were analyzed by thematic approach as guided by the theory proposed by Shediac-Rizkallah & Bone (1998) which identifies; Intervention characteristics, organizational context, and broader environment factors as potentially influential on health programme sustainability.

Results

Intervention characteristics: Provider stigma was reported to have been widespread in the integrated care experience of participating health facilities which necessitated the establishment of stand-alone HIV clinics. HIV disease management was described as highly specialized which necessitated a dedicated workforce and vertical HIV infrastructure such as counselling rooms. Organizational context: Participating health facilities reported health-system capacity constraints in implementing integrated systems of care due to a shortage of ART-proficient personnel and physical space, a lack of laboratory capacity to concurrently conduct HIV and non-HIV tests and increased workloads associated with implementing integrated care. Broader environment factors: Escalating HIV client loads and external HIV funding architectures were perceived to have perpetuated verticalized HIV programming over the past decade.

Conclusion

Our study offers in-depth, contextualized insights into the factors contributing to the endurance of vertical HIV clinics in Uganda. Our analysis suggests that there is a complex interaction in supply-side constraints (shortage of ART-proficient personnel, increased workloads, laboratory capacity deficiencies) and demand-side factors (escalating demand for HIV services, psychosocial barriers to HIV care) as well as the specialized nature of HIV disease management which pose challenges to the integrated-health services agenda.

Success factors for universal access to antiretroviral treatments in South Africa

This article studies the epidemiological and economic impacts of a universal testing and treatment policy of Human Immunodeficiency Virus (HIV) in South Africa. A model of disease transmission is built to simulate several implementation scenarios of the policy. Different behavioral responses in the general population are considered. The results show that the success of a large-scale HIV testing and treatment program in South Africa depends on its implementation conditions. The policy can lead to a reduction of the HIV epidemic, even in the case of a large relapse in preventive behaviors in the general population, if implementation conditions are favorable. This is the case if the number of infected individuals who are infectious is greatly reduced. From an economic point of view, taking into account the positive externality of antiretroviral (ARV) treatments changes the traditional framework of cost-benefit analyses. A large-scale testing and treatment program would be cost-saving in the case of favorable implementation conditions, even following a large increase in risk behaviors after the scaling up of ARV treatments. By contrast, the analysis stresses out the potential perverse effects of scaling up ARV treatments in South Africa if the intervention is set up without ensuring enough resources for patients' monitoring and the availability of effective ARV drugs. Indeed, if the number of treated patients rises while adherence of patients to treatments decreases and the rate of loss to follow-up increases, the policy could extend the pool of infectious patients and lead to a long-term amplification of the epidemic.

The neglected burden of tuberculosis disease among health workers: a decade-long cohort study in South Africa

Background

Health workers (HWs) in resource-limited settings are at high-risk of exposure to tuberculosis (TB) at work. The aim of this study was to estimate the rate of TB disease among HWs in the Free State Province of South Africa between 2002 and 2012 and to compare demographic and clinical characteristics between HWs and the general population with TB. This study also explores the effect of occupational variables on risk of TB among HWs.

Methods

Probabilistic record linkage was utilized to identify HWs who were also registered as TB patients. This historical prospective cohort study calculated incidence rate ratios (IRR) for TB disease among HWs in Free State from 2002 to 2012. Generalized linear mixed-effects regression was used to model the association between sex, race, facility type, occupation, duration of employment, and the rate of TB.

Results

There were 2677 cases of TB diagnosed among HWs from 2002 to 2012 and 1280 cases were expected. The overall TB incidence rate in HWs during the study period was 1496·32 per 100,000 compared to an incidence rate of 719·37 per 100,000 in the general population during the same time period. IRR ranged from 1·14 in 2012 to 3·12 in 2005. HWs who were male, black, coloured and employed less than 20 years had higher risk of TB. Facility type and occupation were not associated with increased risk of TB when adjusted for other covariates.

Conclusion

HWs in South Africa have higher rates of TB than the general population. Improved infection prevention and control measures are necessary in all high-burden TB healthcare settings.

The Importance of the Family: A Longitudinal Study of the Predictors of Depression in HIV Patients in South Africa

As a chronic illness, HIV/AIDS requires life-long treatment adherence and retention-and thus sufficient attention to the psychosocial dimensions of chronic disease care in order to produce favourable antiretroviral treatment (ART) outcomes in a sustainable manner. Given the high prevalence of depression in chronic HIV patients, there is a clear need for further research into the determinants of depression in this population. In order to comprehensively study the predictors of depressive symptoms in HIV patients on ART, the socio-ecological theory postulates to not only incorporate the dominant individual-level and the more recent community-level approaches, but also incorporate the intermediate, but crucial family-level approach. The present study aims to extend the current literature by simultaneously investigating the impact of a wide range individual-level, family-level and community-level determinants of depression in a sample of 435 patients enrolled in the Free State Province of South Africa public-sector ART program. Structural equation modeling is used to explore the relationships between both latent and manifest variables at two time points. Besides a number of individual-level correlates-namely education, internalized and external stigma, and avoidant and seeking social support coping styles-of depressive symptoms in HIV patients on ART, the study also revealed the important role of family functioning in predicting depression. While family attachment emerged as the only factor to continuously and negatively impact depression at both time points, the second dimension of family functioning, changeability, was the only factor to produce a negative cross-lagged effect on depression. The immediate and long-term impact of family functioning on depression draws attention to the role of family dynamics in the mental health of people living with HIV/AIDS. In addition to individual-level and community-based factors, future research activities should also incorporate the role of the family context in research into the mental health of HIV patients, as our results demonstrate that the familial context in which a person with HIV on ART resides is inextricably interconnected with his/her health outcomes.

Clinician perceptions and patient experiences of antiretroviral treatment integration in primary health care clinics, Tshwane, South Africa

Background

Primary Health Care (PHC) clinicians and patients are major role players in the South African antiretroviral treatment programme. Understanding their perceptions and experiences of integrated care and the management of people living with HIV and AIDS in PHC facilities is necessary for successful implementation and sustainability of integration.

Objective

This study explored clinician perceptions and patient experiences of integration of antiretroviral treatment in PHC clinics.

Method

An exploratory, qualitative study was conducted in four city of Tshwane PHC facilities. Two urban and two rural facilities following different models of integration were included. A self-administered questionnaire with open-ended items was completed by 35 clinicians and four focus group interviews were conducted with HIV-positive patients. The data were coded and categories were grouped into sub-themes and themes.

Results

Workload, staff development and support for integration affected clinicians’ performance and viewpoints. They perceived promotion of privacy, reduced discrimination and increased access to comprehensive care as benefits of service integration. Delays, poor patient care and patient dissatisfaction were viewed as negative aspects of integration. In three facilities patients were satisfied with integration or semi-integration and felt common queues prevented stigma and discrimination, whilst the reverse was true in the facility with separate services. Single-month issuance of antiretroviral drugs and clinic schedule organisation was viewed negatively, as well as poor staff attitudes, poor communication and long waiting times.

Conclusion

Although a fully integrated service model is preferable, aspects that need further attention are management support from health authorities for health facilities, improved working conditions and appropriate staff development opportunities.

'Let Us Protect Our Future' a culturally congruent evidenced-based HIV/STD risk-reduction intervention for young South African adolescents

One of the worst HIV/AIDS epidemics in the world is occurring in South Africa, where heterosexual exposure is the main mode of HIV transmission. Young people 15-24 years of age, particularly women, account for a large share of new infections. Accordingly, there is an urgent need for behavior-change interventions to reduce the incidence of HIV among adolescents in South Africa. However, there are few such interventions with proven efficacy for South African adolescents, especially young adolescents. A recent cluster-randomized controlled trial of the 'Let Us Protect Our Future!' HIV/STD risk-reduction intervention for Grade 6 South African adolescents (mean age = 12.4 years) found significant decreases in self-reported sexual risk behaviors compared with a control intervention. This article describes the intervention, the use of the social cognitive theory and the reasoned action approach to develop the intervention, how formative research informed its development and the acceptability of the intervention. Challenges in designing and implementing HIV/STD risk-reduction interventions for young adolescents in sub-Saharan Africa are discussed.
