Challenges in Exploratory Methods for Tuberculosis Research in South Africa

Burden of stigma among tuberculosis patients in a pastoralist community in Kenya: A mixed methods study

BACKGROUND

Tuberculosis (TB) stigma remains a barrier to early diagnosis and treatment completion. Increased understanding of stigma is necessary for improved interventions to minimise TB stigma and its effects. The purpose of this study is to quantitatively measure TB stigma and to explore qualitatively its manifestation among TB patients in a rural Kenyan community.

METHODS

This hospital based study using explanatory sequential mixed methods approach was conducted in 2016. In the quantitative part of the study, a questionnaire containing socio-demographic characteristics and scales measuring perceived TB stigma and experienced TB stigma, was administered to 208 adult pulmonary TB patients receiving treatment in West Pokot County. Respondents with high stigma were purposively selected to take part in in-depth interviews and focus group discussions. The qualitative data were collected through 15 in-depth interviews and 6 focus group discussions with TB patients. Descriptive and bivariate analysis was done for the quantitative data while the thematic analysis was done for qualitative data.

RESULTS

The internal consistency reliability coefficients were satisfactory with Cronbach alphas of 0.87 and 0.86 for the 11-item and 12-item stigma measurement scale. The investigation revealed that TB stigma was high. The key drivers of TB stigma were the association of TB with HIV/AIDS and the fear of TB transmission. TB stigma was exemplified through patients being isolated by others, self-isolation, fear to disclose TB diagnosis, association of TB with human immunodeficiency virus (HIV) and lack of social support. Being a woman was significantly associated with high levels of both experienced stigma (p = 0.007) and perceived stigma (p = 0.005) while age, marital status, occupation and the patient's religion were not.

CONCLUSION

There is a need to implement stigma reduction interventions in order to improve TB program outcomes.

Walking up hills, through history and in-between disciplines: MHH and Health Sciences Education at the tip of Africa

Celebration, frustration, contestation and imagination all manifest themselves when examining the evolution of the field of Medical and Health Humanities (MHH) at the University of Cape Town (UCT). That this field has been growing at the same time as access to, inclusion in, and social justice issues linked to higher education have come under the spotlight has the potential to shape how we think and plan for the future of the field. Doing this will require treks up hills, journeys through difficult histories and dynamic dances in-between disciplines.This article examines MHH at UCT broadly, referring to projects and programmes that are underway primarily in the humanities and health sciences faculties. From this overview, the article specifically examines the curricula changes introduced in the Faculty of Health Sciences inspired by MHH and the author's interest in historical consciousness. It describes current points of intervention in physiotherapy and MBChB undergraduate curricula; and through short-term special study modules that have allowed those interested in MHH to explore relationships between health and healing and art, music, writing, yoga, PhotoVoice, drama, drawing and complex histories.It discusses some of the challenges of introducing humanities teaching into health sciences curricula; and some of the tensions that result from the meeting of divergent epistemologies and pedagogies. The article considers if, and how, MHH might engage with social (in)justice, and inclusions and exclusions and potentially offer a balm to soothe the bruising effects of oppressive histories and a hegemonically hierarchical present.

Engaging adolescents in tuberculosis and clinical trial research through drama

Background

The South African Tuberculosis Vaccine Initiative is based in Worcester where tuberculosis (TB) is endemic, and incidence rates are amongst the highest nationally. In high TB burden settings after an early childhood peak, incidence rates start to rise again in adolescents, therefore they are an important target group for tuberculosis vaccine research. In 2012, learners from a local school developed a one-off theatrical production out of an educational comic book Carina’s Choice, developed by the South African Tuberculosis Vaccine Initiative in 2010. A Wellcome Trust International Engagement grant allowed for this one-off production to be further developed, with input from university students and staff, and rolled out to schools in the Worcester area as an engagement and education intervention.

Methods

Focus group feedback was used to identify key messages and to develop the play’s script. Qualitative methods were used to collect and analyse relevant data. Interviews were conducted with learner-actors, pre- and post-focus group feedback was obtained from a sample of school-going adolescents, and pre- and post-questionnaires were administered to adolescent audience members.

Results

From the pre-drama focus group discussions, topics such as TB symptoms, stigma and transmission were identified as areas that needed attention. After the performances, adolescents showed improved knowledge on the identified topics and they discussed TB prevention measures. They highlighted transmission of TB during pregnancy as a further topic to be addressed in future iterations of the drama. Although stigma is a difficult phenomenon to interpret, post-drama participants understood that TB transmission could occur in all individuals. Learner-actors agreed with focus group participants that the play could impact the wider community if it were rolled out. Feedback from the South African Tuberculosis Vaccine Initiative staff verified that recruitment for an upcoming trial was facilitated by the preparedness that the play provided in recruitment areas. The study showed that before and after evaluations provide data on the usefulness of the play as an education tool.

Conclusions

Theatre, presented and motivated by adolescent peers, can raise awareness of TB, and assist clinical trial preparedness and further engagement between trial staff and their trial community.
