Reducing HIV- and TB-Stigma among healthcare co-workers in South Africa: Results of a cluster randomised trial

Learning interventions and training methods in health emergencies: A scoping review

BACKGROUND

Keeping the health workforce and the public informed about the latest evolving health information during a health emergency is critical to preventing, detecting and responding to infectious disease outbreaks or other health emergencies. Having a well-informed, ready, willing, and skilled workforce and an informed public can help save lives, reduce diseases and suffering, and minimize socio-economic loss in affected communities and countries. Providing "just in time" support and opportunities for learning in health emergencies is much needed for capacity building. In this paper, 'learning intervention' refers to the provision of ad-hoc, focused, or personalized training sessions with the goal of preparing the health workers for emergencies or filling specific knowledge or skill gaps. We refer to 'training methods' as instructional design strategies used to teach someone the necessary knowledge and skills to perform a task.

METHODS

We conducted a scoping review to map and better understand what learning interventions and training methods have been used in different types of health emergencies and by whom. Studies were identified using six databases (Pubmed/Medline, Embase, Hinari, WorldCat, CABI and Web of Science) and by consulting with experts. Characteristics of studies were mapped and displayed and major topic areas were identified.

RESULTS

Of the 319 records that were included, contexts most frequently covered were COVID-19, disasters in general, Ebola and wars. Four prominent topic areas were identified: 1) Knowledge acquisition, 2) Emergency plans, 3) Impact of the learning intervention, and 4) Training methods. Much of the evidence was based on observational methods with few trials, which likely reflects the unique context of each health emergency. Evolution of methods was apparent, particularly in virtual learning. Learning during health emergencies appeared to improve knowledge, general management of the situation, quality of life of both trainers and affected population, satisfaction and clinical outcomes.

CONCLUSION

This is the first scoping review to map the evidence, which serves as a first step in developing urgently needed global guidance to further improve the quality and reach of learning interventions and training methods in this context.

Systematic review and quantitative and qualitative comparative analysis of interventions to address HIV-related stigma and discrimination

A strong global commitment exists to eliminate HIV-related stigma and discrimination, and multiple strategies to reduce or eliminate stigma and discrimination have been tried. Using a PICOTS framework and applying the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria, we undertook a systematic review to determine the success of interventions aiming to address internalized stigma, stigma and discrimination in healthcare, and at the legal or policy level, and to identify their critical success factors. Random effects meta-analyses summarized results wherever possible. We carried out a component analysis to identify and characterize successful interventions. Internalized stigma interventions were diverse: across all studies, we found a reduction of stigma but it was not statistically significant [standardized mean difference (SMD) 0.56; confidence interval (CI) 0.31-1.02; 17 studies). For interventions to address stigma and discrimination in healthcare settings, effect estimates varied considerably but most studies showed positive effects (SMD 0.71; CI 0.60-0.84, 8 studies). Boosted regression analyses found that a combined approach comprising education, counseling, community participation, support person, and access to a HIV specialist often yielded success. Studies of efforts to address stigma and discrimination through law and policy documented, mostly qualitatively, the effect of court cases and directives. Across a range of settings and populations, promising interventions have been identified that, through diverse pathways, have positively impacted the types of stigma and discrimination studied. This evidence base must be built upon and brought to scale to help reach global HIV-related targets and, most importantly, improve the health and quality of life of people with HIV.

"I don't know if you have searched through the scriptures to find a reference on HIV/AIDS. I mean there isn't going to be one, right?": HIV stigma solutions from dialogues between faith leaders and health care workers

In South African communities, both faith leaders and health care workers play a vital role in supporting the health of community members and people living with HIV in particular. This study describes HIV stigma when faith leaders and health care workers engaged in discourse. The study used a descriptive qualitative inquiry design. Data were gathered between 2015 and 2016 in the areas of Masiphumelele and Gugulethu in Cape Town, South Africa. Three themes emerged: (1) participants identified influences that can increase HIV stigma; (2) participants shared the challenges that they face to reduce HIV stigma; and (3) participants suggested solutions to reduce HIV stigma. Themes discussed include ground-level problems and practical solutions to address HIV stigma in faith communities. Collaboration between faith leaders and health care workers are vital resources in the fight against HIV stigma. Future research and interventions should aim to promote organised collaboration between faith communities and health care structures.

Interventions pathways to reduce tuberculosis-related stigma: a literature review and conceptual framework

BACKGROUND

Prevention of tuberculosis (TB)-related stigma is vital to achieving the World Health Organisation's End TB Strategy target of eliminating TB. However, the process and impact evaluation of interventions to reduce TB-stigma are limited. This literature review aimed to examine the quality, design, implementation challenges, and successes of TB-stigma intervention studies and create a novel conceptual framework of pathways to TB-stigma reduction.

METHOD

We searched relevant articles recorded in four scientific databases from 1999 to 2022, using pre-defined inclusion and exclusion criteria, supplemented by the snowball method and complementary grey literature searches. We assessed the quality of studies using the Crowe Critical Appraisal Tool, then reviewed study characteristics, data on stigma measurement tools used, and interventions implemented, and designed a conceptual framework to illustrate the pathways to TB-stigma reduction in the interventions identified.

RESULTS

Of 14,259 articles identified, eleven met inclusion criteria, of which three were high quality. TB-stigma reduction interventions consisted mainly of education and psychosocial support targeted predominantly toward three key populations: people with TB, healthcare workers, and the public. No psychosocial interventions for people with TB set TB-stigma reduction as their primary or co-primary aim. Eight studies on healthcare workers and the public reported a decrease in TB-stigma attributed to the interventions. Despite the benefits, the interventions were limited by a dearth of validated stigma measurement tools. Three of eight studies with quantitative stigma measurement questionnaires had not been previously validated among people with TB. No qualitative studies used previously validated methods or tools to qualitatively evaluate stigma. On the basis of these findings, we generated a conceptual framework that mapped the population targeted, interventions delivered, and their potential effects on reducing TB-stigma towards and experienced by people with TB and healthcare workers involved in TB care.

CONCLUSIONS

Interpretation of the limited evidence on interventions to reduce TB-stigma is hampered by the heterogeneity of stigma measurement tools, intervention design, and outcome measures. Our novel conceptual framework will support mapping of the pathways to impacts of TB-stigma reduction interventions.

How the 'HIV/TB co-epidemic-HIV stigma-TB stigma' syndemic impacts on the use of occupational health services for TB in South African hospitals: a structural equation modelling analysis of the baseline data from the HaTSaH Study (cluster RCT)

INTRODUCTION

Tuberculosis (TB) has become an occupational health hazard in South African hospitals where healthcare workers (HCWs) are additionally confronted daily with HIV and its associated stigma, causing a syndemic. Early TB diagnosis and treatment are vital, but the uptake of these services through occupational healthcare units (OHUs) is low. The current study hypothesises that (1) the link between HIV and TB and (2) the perceived HIV stigmatisation by colleagues create (3) a double HIV-TB stigma which increases (4) internalised TB stigma and leads to (5) a lower willingness to use OHU services for TB screening and treatment.

DESIGN

A cross-sectional study using the baseline data from the HIV and TB Stigma among Healthcare workers Study (HaTSaH Study).

SETTING

Six hospitals in the Free State province of South Africa.

PARTICIPANTS

820 HCWs of the six selected hospitals.

RESULTS

The study results demonstrate that the co-epidemic (β=0.399 (screening model) and β=0.345 (treatment model)) combined (interaction effect: β=0.133 (screening) and β=0.132 (treatment)) with the persistent stigmatisation of HIV is altering the attitudes towards TB (β=0.345 (screening) and β=0.400 (treatment)), where the stigmatising views of HIV are transferred to TB-illustrating the syndemic impact. Our model demonstrated that this syndemic not only leads to higher levels of internal TB stigma (β=0.421 (screening) and β=0.426 (treatment)), but also to a lower willingness to use the OHU for TB screening (probit coefficient=-0.216) and treatment (probit coefficient=-0.160). Confidentiality consistently emerged as a contextual correlate of OHU use.

CONCLUSIONS

Theoretically, our results confirm HIV as a 'syndemic generator' which changes the social meaning of TB in the hospital context. Practically, the study demonstrated that the syndemic of TB and HIV in a highly endemic context with stigma impacts the intended use of occupational TB services.
