Understanding hard-to-reach communities: local perspectives and experiences of trachoma control among the pastoralist Maasai in northern Tanzania

Acceptability and feasibility of tests for infection, serological testing, and photography to define need for interventions against trachoma

BACKGROUND

Trachoma causes blindness due to repeated conjunctival infection by Chlamydia trachomatis (Ct). Transmission intensity is estimated, for programmatic decision-making, by prevalence of the clinical sign trachomatous inflammation-follicular (TF) in children aged 1-9 years. Research into complementary indicators to field-graded TF includes work on conjunctival photography, tests for ocular Ct infection, and serology. The perceived acceptability and feasibility of these indicators among a variety of stakeholders is unknown.

METHODOLOGY

Focus group discussions (FGDs) with community members and in-depth interviews (IDIs) with public health practitioners in Tanzania were conducted. FGDs explored themes including participants' experience with, and thoughts about, different diagnostic approaches. The framework method for content analysis was used. IDIs yielded lists of perceived strengths of, and barriers to, implementation for programmatic use of each indicator. These were used to form an online quantitative survey on complementary indicators distributed to global stakeholders via meetings, mailing lists, and social media posts.

RESULTS

Sixteen FGDs and 11 IDIs were conducted in October-November 2022. In general, all proposed sample methods were deemed acceptable by community members. Common themes included not wanting undue discomfort and a preference for tests perceived as accurate. Health workers noted the importance of community education for some sample types. The online survey was conducted in April-May 2023 with 98 starting the questionnaire and 81 completing it. Regarding barriers to implementing diagnostics, the highest agreement items related to feasibility, rather than acceptability. No evidence of significant differences was found in responses pertaining to community acceptability based on participant characteristics.

CONCLUSIONS

All of the indicators included were generally deemed acceptable by all stakeholders in Tanzania, although community education around the benefits and risks of different sample types, as well as addressing issues around feasibility, will be key to successful, sustainable integration of these indicators into trachoma programs.

'Follow the cattle': a joint cross-border trachoma MDA perspective

Trachoma, a disease caused by Chlamydia trachomatis, is the leading infectious cause of blindness. To fight it, endemic East African countries adopted the World Health Organization's SAFE Strategy, targeting surgery, antibiotics through mass drug administration (MDA), facial cleanliness and environmental improvement. Trachoma persists among nomadic communities along the Kenya-Uganda and Kenya-Tanzania borders. To address this, Kenya, Tanzania and Uganda launched synchronized MDA campaigns, simultaneously treating populations across borders. Successes included joint planning, community involvement and intergovernmental cooperation, although challenges remained in resourcing MDA cross-border focal points and in addressing coverage and funding. Novel strategies like synchronized joint cross-border MDA with community engagement are vital for sustainable trachoma elimination in these nomadic settings.

Understanding the Role of Gender in Trichiasis Case Finding in Tanzania

PURPOSE

Despite the importance of trachomatous trichiasis (TT) case-finding activities in national trachoma elimination campaigns, the scientific literature on the determinants of good outcomes - finding and managing all TT cases - is still sparse. In Tanzania, we studied differences in case finding activities and outcomes between male and female case finders.

METHODS

This case study was conducted in two districts in Tanzania in 2021-2022. Quantitative data were extracted from case finder forms and outreach registers, and qualitative data were collected through direct observation, interviews, and focus group discussions.

RESULTS

Across both districts, more males were trained as case finders (68%). Productivity differences were minor, not statistically significant, between male and female case finders regarding the number of households visited and the number of adults examined. Whether identified by a male or female case finder, similar proportions of men and women suspected to have TT were subsequently managed. There is evidence that suggests that female case finders were more active in supporting suspected and confirmed TT cases to access follow-up services.

CONCLUSION

The findings do not suggest that gender balance in the recruitment of TT case finders would have led to better TT campaign outcomes in the study districts. Programmes may benefit from integrating gender considerations in the design and implementation of case finding activities - e.g. in monitoring gender differences among case finders and the relationship with key outcomes. This study also highlights how women with TT face greater barriers to care.

The role of cultural safety and ethical space within postcolonial healthcare for Maasai in Tanzania

The history of the Maasai tribe in northern Tanzania is characterised by marginalisation, discrimination and political subjugation. Inequities, enacted through power relations, influence healthcare access, practices and outcomes among the Maasai. Cultural safety and ethical space provide lenses into social, political and historical influences on access to care, helping to understand the realities of historically marginalised populations such as the Maasai, and responses to health services. This study aims to examine Maasai experiences of accessing and uptake of health services within a postcolonial discourse in Tanzania. In an ethnographic study examining access and perceptions of healthcare services in Maasai communities, lead authors conducted participant observations and at health facilities to document experiences. Household interviews, a group oral history and interviews with NGOs working with Maasai communities, contributed to the data analysed. Inductive thematic analysis was used to understand healthcare experiences within a framework of cultural safety and ethical space. Despite trust in biomedicine, Maasai people have a strong desire for health services with particular characteristics. Quality of care, including facilities and diagnostics available and used, was important. A sense of fairness was a determinant in respecting services including 'first come first serve' system and transparency when unable to treat a condition. Trust in health services was also influenced by personal interactions with health workers, including provision of health information provided to patients and instances of being mistreated. These findings offer an understanding of ways in which spaces of healthcare can be more approachable and trusted by Maasai. Incorporating cultural safety and ethical spaces to understand healthcare access can help to reduce the power imbalance possibly resulting from a history of marginalisation. This can inform development of culturally appropriate programmes, used to educate healthcare professionals and advocate for improved healthcare services for marginalised groups.

On the Multiple Identities of Stakeholders in Wolf Management in Minnesota, United States

Social identity theory offers a means to understand attitudes about wolves, with consequences for management support. Using data from a mail survey about wolves, we explored relationships among seven identities (i.e., wolf advocate, hunter, environmentalist, nature enthusiast, farmer, trapper, conservationist) using multidimensional scaling (MDS) and principal components analysis (PCA). We examined how identities correlated with political ideology, trust in a wildlife management agency, wildlife value orientations (WVOs) and attitudes about wolves, and we evaluated whether WVOs mediated the relationship between identities and attitudes. PCA suggested two factors in identifying relationships among stakeholders, while MDS and correlations found diversity among stakeholders beyond these factors. Hunter identity was most strongly associated with a domination WVO and conservative political ideology. Farmer identity was most strongly associated with agency distrust and negative wolf attitudes. Wolf advocate was most strongly associated with a mutualism WVO (i.e., beliefs that humans are meant to coexist in harmonious relationships with wildlife), agency trust, and positive wolf attitudes. Conservationist identity was positively correlated with all other identities. WVOs partially mediated the relationship between identities and attitudes.

Leaving no one behind: targeting mobile and migrant populations with health interventions for disease elimination-a descriptive systematic review

BACKGROUND

Mobile and migrant populations (MMPs) pose a unique challenge to disease elimination campaigns as they are often hard to survey and reach with treatment. While some elimination efforts have had success reaching MMPs, other campaigns are struggling to do so, which may be affecting progress towards disease control and elimination. Therefore, this paper reviews the literature on elimination campaigns targeting MMPs across a selection of elimination diseases-neglected tropical diseases, malaria, trypanosomiasis, polio, smallpox, and rinderpest.

METHODS

Through a systematic review process following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a three-person review team identified papers from databases, conference records, and citation searches using inclusion/exclusion criteria. Papers were divided into three key outcome domains during the synthetization process: (1) MMP movement patterns in East Africa including reasons for movement and consequences in terms of health outcomes and healthcare access; (2) MMP contribution to the transmission of disease across all geographies; (3) surveillance methods and treatment interventions used to implement programming in MMPs across all geographies. Experts in the field also provided supplemental information and gray literature to support this review.

RESULTS

The review identified 103 records which were descriptively analyzed using the outcome domains. The results indicate that in East Africa, there are various motivations for migration from economic opportunity to political unrest to natural disasters. Regardless of motivation, mobile lifestyles affect health service access such that MMPs in East Africa report barriers in accessing healthcare and have limited health knowledge. Often lower service delivery to these populations has resulted in higher disease prevalence. A minority of articles suggest MMPs do not pose challenges to reaching disease control and elimination thresholds. Finally, the literature highlighted surveillance methods (e.g., using satellite imagery or mobile phone data to track movement, participatory mapping, snowball sampling) and intervention strategies (e.g., integration with animal health campaigns, cross-border coordination, alternative mass drug administration [MDA] methods) to implement health interventions in MMPs.

CONCLUSIONS

Ultimately, the literature reviewed here can inform programmatic decisions as the community attempts to reach these never treated populations.

Implementing trachoma control programmes in marginalised populations in Tanzania: A qualitative study exploring the experiences and perspectives of key stakeholders

BACKGROUND

Despite aspects of the SAFE strategy for reducing trachoma in Tanzania have been somewhat successful, the disease still persists in marginalised communities even with repeated trachoma control interventions. This study aims to understand the facilitators and barriers associated with implementing trachoma control programmes in these communities, from the perspective of non-governmental organisations (NGOs).

METHODS

Participants were the representatives of NGOs who had knowledge and experience in the implementation of trachoma control programmes. Data was collected using in-depth, semi-structured interviews guided by a topic guide, which was updated after each interview using a constant comparative method. Interviews were audio-recorded and then transcribed verbatim. Thematic analysis was done inductively. Codes were generated from the transcripts and then clustered into themes.

FINDINGS

The context within marginalised communities often acted as a perceived barrier to successful implementation of control programmes. This included poor environmental cleanliness, lack of trust, poor disease knowledge and traditional lifestyles. Community values could either be a facilitator or a barrier, depending on the scenario. The anatomical location of the disease and the poor understanding of the disease progression also served as barriers. Considerations affecting decision-making among NGO's include financial feasibility, community needs and whether the quality of the intervention could be improved. NGOs felt that the collaboration and the opportunity to learn from other organisations were beneficial aspects of having different actors. However, this also resulted in variability in the effectiveness of interventions between districts.

CONCLUSION

NGOs should focus on behaviour change and health education that is tailored to marginalised communities and seek innovative ways to implement trachoma intervention programmes whilst being minimally intrusive to the traditional way of life. Partners should also implement ways to ensure high quality programmes are being provided, by increasing staff accountability and compensating volunteers fairly.

Empowering Maasai women behind the camera: Photovoice as a tool for trachoma control

BACKGROUND

Photovoice is a method used to help engage community members to understand local realities and promote social change. Photovoice uses cameras in the hands of participants as a tool to visually document a specified topic. Photos taken by participants allow for reflection and stimulate dialog on an issue to ideally lead to social change. Trachoma, hyperendemic in Maasai communities in Northern Tanzania, is the commonest infectious cause of blindness worldwide, caused by chlamydia trachomatis. The bacterial infection commonly occurs in childhood and over many years repeated infections leads to inflammation and scarring of the eyelid. Often as adults this leads to the upper eyelid turning inward and eyelashes scratching the eye, resulting in pain and eventually blindness. We used photovoice as a tool for Maasai women to share their lived experiences of educating peers on trachoma and ultimately empowering women in this society.

METHODS

This public engagement intervention was conducted September thru October 2017. We held a workshop on trachoma control for 20 Maasai women including use of photovoice method. Women were asked to disseminate information from the trachoma control workshop to their community and to capture their experiences using disposable cameras. Five weeks post-workshop we facilitated a discussion and women displayed photos of the successes and challenges they encountered as advocates for trachoma control in their community.

INTERVENTION OUTCOMES

It was observed throughout the process and at the photo discussion meeting, that women articulated empowerment by this experience; as educators, agents of change and a source of valued information.

CONCLUSION

Photovoice should be considered for future interventions as a communication tool on health issues and to empower women to be ambassadors for health promotion.
