Research questionHow can offline clinical decision support aid differential diagnosis when connectivity and hardware are limited?In rural sub-Saharan Africa, frontline workers may lack specialist support, dependable connectivity, and hardware for conventional AI tools. This makes it difficult to provide diagnostic reasoning locally without cloud infrastructure.

Latest papersRecent research connected to this question, newest first.Aletheia: An Offline-First Clinical Decision Support System for Differential Diagnosis in Low-Resource Healthcare SettingsThe evidence concerns Aletheia, an offline-first system based on Qwen2.5-3B-Instruct and fine-tuned for 50 disease conditions prevalent in East Africa. It uses approximately 3,630 MB of peak inference RAM within a 7,168 MB benchmark limit and reports Top-1 and Top-3 diagnostic accuracy, calibration, and language-generation scores. Diagnostic results come from only ten representative cases, with wide confidence intervals, so they are indicative rather than statistically robust.research paper · Sep 4, 2026
