Abstract
Recent advancements in biomedical engineering have focused on developing cost-effective diagnostic devices for resource-limited settings (RLS), particularly in South Africa where healthcare infrastructure is underdeveloped and access to advanced medical equipment is scarce. A randomized controlled trial (RCT) design was employed with participants from public health clinics in South Africa's resource-limited regions. Diagnostic devices were rigorously tested under varying environmental conditions to ensure reliability and efficiency. The findings indicate a significant improvement in diagnostic accuracy, with a mean error rate reduction of 20% across all sample types compared to conventional methods (95% confidence interval: -18% to -23%). These results suggest that the newly developed diagnostic devices can reliably support healthcare providers in resource-limited settings, potentially reducing delays and misdiagnoses. Further research is recommended to validate these findings across a wider population and to explore potential integration into existing healthcare systems. Additionally, cost-effectiveness analyses should be conducted to ensure sustainability.
