Uganda faces challenges in accessing affordable and reliable diagnostic devices for healthcare providers in resource-limited settings. In-depth interviews with researchers involved in the development of diagnostic devices were conducted. Data collection focused on qualitative insights into innovation processes and outcomes. Participants reported that the new diagnostic device reduced healthcare costs by $5 per test, achieving a success rate of 90% in field trials compared to traditional methods. The study underscores the importance of local biomedical engineering expertise for developing cost-effective solutions to global health challenges. Further research should explore scalability and sustainability of these innovations in diverse settings across Africa. biomedical engineering, diagnostic devices, resource-limited settings, Uganda The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.
