Syphilis self-testing to expand test uptake among men who have sex with men: a theoretically informed mixed methods study in Zimbabwe

ABSTRACT Objectives Self-testing for STIs such as HIV and syphilis may empower sexual minorities and expand uptake of STI testing. While much is known about HIV self-testing (HIVST), less is known about syphilis self-testing, particularly in low-income settings. The objective of this study is to determine context-specific facilitators and barriers for self-testing and to assess the usability of syphilis self-testing in Zimbabwe among men who have sex with men (MSM). Methods This mixed methods study was conducted in Harare as part of a larger syphilis self-testing trial. The study included in-depth interviews (phase one) followed by usability testing and a second interview (phase two). In-depth interviews were conducted with MSM and key informants prior to syphilis self-testing. The same MSM then used the syphilis self-test, quantitatively assessed its usability and participated in a second in-depth interview. Phase one data was analysed using a thematic approach, guided by an adapted Social Ecological Model conceptual framework. Phase two interviews were analysed using Rapid Assessment Procedure qualitative methodology, and usability was assessed using a pre-established index, adapted from existing HIVST evaluation scales. Results Twenty MSM and 10 key informants were recruited for phase one in-depth interviews and 16 of these MSM participated in phase two by completing a syphilis self-test kit. Facilitating factors for self-testing included the potential for increased privacy, convenience, autonomy and avoidance of social and healthcare provider stigma. Barriers included the fear to test and uncertainty about linkage to care and treatment. Data from the usability index suggested high usability (89.6% on a 0-100 scale) among the men who received the self-test. Conclusions MSM in Zimbabwe were willing to use syphilis self-test kits and many of the barriers and facilitators were similar to those observed for HIVST. Syphilis self-testing may increase syphilis test uptake among sexual minorities in Zimbabwe and other low- and middle-income countries. Key messages Syphilis self-testing is an empowering, innovative tool that can be used to expand uptake of STI testing among sexual minorities in Zimbabwe.Facilitators and barriers for syphilis self-testing are similar to those observed for HIV self-testing in Zimbabwe and other low- and middle-income countries. Participants reported high self-test usability and found that self-testing provided increased privacy, convenience and autonomy in comparison to facility-based testing

Feasibility and economic costs of syphilis self-testing to expand test uptake among gay, bisexual and transgender men: results from a randomised controlled trial in Zimbabwe

Background Access to syphilis testing and treatment is frequently limited for men who have sex with men (MSM). A two-armed randomised controlled trial compared feasibility and costs of facility-based syphilis testing with self-testing among MSM in Zimbabwe. Methods This randomised controlled trial was conducted in Harare, with participants randomised 1:1. Syphilis self-testing was offered in community-based settings. The primary outcome was the relative proportion of individuals taking up testing. Total incremental economic provider and user costs, and cost per client tested, diagnosed and treated were assessed using ingredients-based costing in 2020 US$. Results A total of 100 men were enrolled. The two groups were similar in demographics. The mean age was 26 years. Overall, 58$859 and US$736, and cost per test US$30 and US$15 for respective arms. Cost per reactive test was US$107 and US$123, and per client treated US$215 and US$184, respectively. The syphilis test kit was the largest cost component. Total user cost per client per visit was US$9. Conclusion Syphilis self-testing may increase test uptake among MSM in Zimbabwe. However, some barriers limit uptake including lack of self-testing and poor service access. Bringing syphilis testing services to communities, simplifying service delivery and increasing self-testing access through community-based organisations are useful strategies to promote health-seeking behaviours among MSM

Enhancing community participation in dengue control through digital crowdsourcing: An analysis of a World Mosquito Program digital open call in Sri Lanka.

BACKGROUND: Two crowdsourcing open calls were created to enhance community engagement in dengue control in Sri Lanka. We analyzed the process and outcomes of these digital crowdsourcing open calls. METHODS: We used standard World Health Organization (WHO) methods to organize the open calls which used exclusively digital methods because of COVID-19. We collected and analyzed socio-demographic information and digital engagement metrics from each submission. Submissions in the form of textual data describing community-led strategies for mosquito release were coded using grounded theory. RESULTS: The open calls received 73 submissions. Most people who submitted ideas spoke English, lived in Sri Lanka, and were 18 to 34 years old. The total Facebook reach was initially limited (16,161 impressions), prompting expansion to a global campaign which reached 346,810 impressions over 14 days. Diverse strategies for the distribution of Wolbachia-infected mosquito boxes were identified, including leveraging traditional festivals, schools, and community networks. Fifteen submissions (21%) suggested the use of digital tools for monitoring and evaluation, sharing instructions, or creating networks. Thirteen submissions (18%) focused on social and economic incentives to prompt community engagement and catalyze community-led distribution. CONCLUSIONS: Our project demonstrates that digital crowdsourcing open calls are an effective way to solicit creative and innovative ideas in a resource-limited setting

Crowdfunding for health research: a qualitative evidence synthesis and a pilot programme.

BACKGROUND: Many low-income and middle-income country (LMIC) researchers have disadvantages when applying for research grants. Crowdfunding may help LMIC researchers to fund their research. Crowdfunding organises large groups of people to make small contributions to support a research study. This manuscript synthesises global qualitative evidence and describes a Special Programme for Research and Training in Tropical Diseases (TDR) crowdfunding pilot for LMIC researchers. METHODS: Our global systematic review and qualitative evidence synthesis searched six databases for qualitative data. We used a thematic synthesis approach and assessed our findings using the GRADE-CERQual approach. Building on the review findings, we organised a crowdfunding pilot to support LMIC researchers and use crowdfunding. The pilot provided an opportunity to assess the feasibility of crowdfunding for infectious diseases of poverty research in resource-constrained settings. RESULTS: Nine studies were included in the qualitative evidence synthesis. We identified seven findings which we organised into three broad domains: public engagement strategies, correlates of crowdfunding success and risks and mitigation strategies. Our pilot data suggest that crowdfunding is feasible in diverse LMIC settings. Three researchers launched crowdfunding campaigns, met their goals and received substantial monetary (raising a total of US$26 546 across all three campaigns) and non-monetary contributions. Two researchers are still preparing for the campaign launch due to COVID-19-related difficulties. CONCLUSION: Public engagement provides a foundation for effective crowdfunding for health research. Our evidence synthesis and pilot data provide practical strategies for LMIC researchers to engage the public and use crowdfunding. A practical guide was created to facilitate these activities across multiple settings
