In rural Nepal, poor road and transport networks and few testing laboratories impede tuberculosis diagnosis. A drone transport system was established to transport sputum samples to laboratories with advanced molecular diagnostic machines – GeneXpert MTB/RIF. This study explored the perceptions of using drones for tuberculosis diagnosis among community stakeholders, female community health volunteers, and healthcare providers from communities with drones implemented and without drone programs. In December 2019, we conducted focus group discussions in two drone-implemented and three without drone programs. We purposively selected 40 participants: Female community health volunteers (n=16), community stakeholders (n=18), and healthcare providers (n=6). Focus group discussions employed semi-structured questions, which were audio-recorded, transcribed, and translated into English. Codebook thematic analysis was performed and charted using three levels of the socioecological model: individual, community, and health system. We identified four themes (i) Trust in drones underpins successful use for tuberculosis diagnosis; (ii) Drone-based sample transport optimised connectivity and accessibility for people with tuberculosis and healthcare providers; (iii) Drones create opportunities to improve community and health system, and (iv) External factors impede the use of drones to facilitate tuberculosis diagnosis. The study reported, at an individual level, people’s trust in drones mainly through community-based events. For local healthcare providers, drones reduce transport time, opportunity costs, and immediate cash costs of transport. At the community level, drone use creates opportunities to increase the skills of local people as drone pilots. At the health system level, drone transport increases efficient sputum sample delivery and provides opportunities to transport medicines and other biomedical samples. Perceived challenges of using drones were adverse weather, limitations in skilled human resources, and financial resources to operate drones sustainably. Healthcare providers, female community health volunteers, and community stakeholders reported high levels of trust in drones and perceived their use for tuberculosis diagnosis and care to substantially benefit people with tuberculosis and providers in rural Nepal. There was a high level of demand for application to other healthcare services and wider geographical coverage, demonstrating drones as a potential tool for enhancing access to healthcare in geographically remote communities.
