To understand the political, economic, social and technological facilitators and barriers in obtaining an HIV diagnosis to inform implementation strategies for HIV diagnostics in the Dominican Republic (DR).

In-depth, semi-structured qualitative interviews.

A high complexity public hospital in Santiago de los Caballeros, DR.

A convenience and purposive sample of 36 internal medicine physicians and laboratory personnel involved in sample collection, sample analysis or oversight of biological sample analysis.

Using the Social Ecological Model, our results highlighted several interrelated barriers and facilitators to sample analysis at the individual (patient), interpersonal (interactions between laboratory personnel, physicians and patients), organisational (the hospital), community (Santiago de Los Caballeros) and societal (the DR) levels. Some key findings include the importance of psychological support in receiving an HIV diagnosis, how spoken language can be a barrier to care, how inconsistent access to laboratory supplies is a barrier for patients, laboratory personnel and clinicians, and the importance of government public health investment.

Employing qualitative methods to investigate a bioengineering challenge yielded rich data on the sociotechnical implementation context of HIV diagnostics in the DR. Several context-relevant suggestions were developed for HIV diagnostic developers which include incorporating psychological support into the diagnosis workflow, delivering information in multiple languages (ie, Haitian Creole and Spanish) and with non-stigmatising phrasing, working with the public sector to develop and implement technologies, and reducing the supply chain reliance on high-income countries to lessen delays in care. These findings can apply to other types of health technologies and settings and demonstrate the importance of utilizing human-centered design to understand implementation context and promote global health equity in health technology development and adoption.

India targets to eliminate lymphatic filariasis (LF) in alignment with the global goals. By 2024, 106 out of a total of 345 endemic districts have passed all three serial transmission assessment surveys (TAS) and are under post-mass drug administration (MDA) surveillance for a variable period. However, the current epidemiological situation of LF is not known in these districts. With increased mobility of population from the endemic districts currently under MDA to these post-MDA areas, resurgence of LF in these areas cannot be ruled out. Therefore, a study is planned to understand the current LF status in areas under post-MDA surveillance with the following objectives: (1) To assess the epidemiological situation of LF in terms of human and vector infection prevalence in selected evaluation units (EUs) under different durations of post-MDA phase and (2) to estimate the filarial infection (in terms of filarial antigen and microfilaria) among migrants (from endemic districts) in these EUs.

This cross-sectional study will measure the filarial infection in (1) adult population aged ≥20 years (following the WHO 2025 protocol for monitoring and evaluation of MDA) among general population (n=3150 per EU), (2) migrant population (aged 2 years and above) in the post-MDA area originating from endemic areas (n=1000 per EU) and (3) vectors (n=7500 per EU) using molecular xenomonitoring (MX) to confirm sustenance of transmission interruption or identify any potential risk of resurgence in three EUs under post-MDA phase. In one MDA-naive EU that shares borders with endemic districts, filarial infection status will be assessed in (1) school children aged 9–14 years (as per WHO mini-TAS protocol, n=480), (2) migrants (aged 2 years and above) from endemic areas (n=1000) and (3) vectors (n=7500). EU-wide prevalence of microfilaria, circulating filarial antigen and vector infection rates with 95% CIs will be estimated. Multivariate logistic regression analysis will be carried out to find factors associated with LF positivity. In addition, knowledge, attitude and practice surveys will also be conducted among the adult migrants (n=1000 per EU). Thirty in-depth interviews will be conducted among the migrants, local community and health workers (in each EU) and the results will be suitably analysed and triangulated. The study results will enable the national programme to confirm sustenance of transmission interruption or assist in taking a decision to reinitiate MDA in these areas under post-MDA surveillance. It will also enable devising specific strategies to treat migrants.

This study has been approved by the institutional ethics committee (IHEC 03-0824/N/F). A workshop will be held with all stakeholders to disseminate the study findings.
