==AI can improve health care most where expert time is scarce, especially by helping less specialized workers do harder tasks, expanding screening, and improving some decisions and system operations.[:cite[1]{ln=4}] [:cite[2]{ln=2}] [:cite[3]{ln=2}]== Support frontline health workers: The report says AI can help address shortages of teachers and health care workers who interact directly with citizens, although the evidence is still emerging.[:cite[4]{ln=2}] In low and middle income settings, AI can help less experienced workers perform more advanced cognitive tasks and can shift some work away from scarce specialists.[:cite[5]{ln=2}] [:cite[2]{ln=2}] Improve screening and early detection: One of the strongest areas is medical imaging .[:cite[6]{ln=1}] AI systems in imaging can often match or outperform human specialists in detecting anomalies in medical images.[:cite[6]{ln=3}] The report says this matters especially because there is a severe global shortage of radiologists, with fewer than 1,000 radiologists serving low income countries as a group.[:cite[6]{ln=4}] [:cite[6]{ln=6}] Expand access through task shifting: AI assisted imaging can allow screening tasks to be decentralized and shifted to lower level providers, which can lead to earlier detection of abnormalities and better patient outcomes if regulatory hurdles are overcome.[:cite[7]{ln=3}] [:cite[7]{ln=4}] The report gives diabetic retinopathy screening as a strong example: in Bangladesh, AI based screening increased the number of patients screened per day by 39.5 percent , and in Rwanda AI image grading increased referral adherence by 30.1 percent .[:cite[8]{ln=3}] [:cite[8]{ln=4}] Help with tuberculosis screening: The report describes AI assisted TB screening from chest X rays as another mature and evidence backed application.[:cite[9]{ln=1}] WHO recommended computer aided detection for TB screening in 2021, and by 2025 multiple commercial AI solutions had passed independent WHO tests.[:cite[9]{ln=2}] [:cite[9]{ln=3}] AI screening can identify asymptomatic TB cases and can also flag other lung anomalies, while reducing reliance on scarce radiologist time.[:cite[9]{ln=6}] [:cite[10]{ln=4}] [:cite[10]{ln=5}] Offer clinical decision support in primary care: Large language models have shown promise for answering clinical questions, structuring patient records, and supporting decision making by health workers in low resource settings.[:cite[11]{ln=2}] In simulated patient cases, their diagnostic performance rivaled that of general physicians.[:cite[11]{ln=3}] But the report is cautious: as of early 2026, evidence on LLM based clinical decision support in low and lower middle income countries was mixed .[:cite[12]{ln=1}] In Kenya, such a system improved documentation and adherence to guidelines but did not significantly improve clinical outcomes.[:cite[12]{ln=2}] Improve triage and service efficiency: Predictive AI can help process information at the individual level and provide outputs tailored to specific people and contexts.[:cite[13]{ln=2}] The report explicitly notes applications ranging from improving patient triage to relieving pressure on medical staff.[:cite[13]{ln=3}] Improve health system operations: Beyond direct clinical use, AI can help governments improve forecasts, allocate scarce resources, and track and manage programs better.[:cite[4]{ln=1}] The report also notes evidence of AI helping with supply chain and operational tasks in health systems, including references to optimization of vaccination and other public service delivery functions.[:cite[14]{ln=1}] [:cite[15]{ln=1}] ==The main message is that AI’s biggest health care value is usually augmentation and expansion of access , not replacing clinicians outright.[:cite[16]{ln=2}] [:cite[16]{ln=3}] [:cite[16]{ln=4}]== But the report also stresses major limits: Evidence relevant for policy in low resource frontline health care is still scarce .[:cite[17]{ln=1}] Out of nearly 10,000 AI health intervention studies screened, fewer than 1 percent met key relevance criteria for low resource settings, and only 17 studies provided causal evidence on health, quality, or efficiency outcomes.[:cite[18]{ln=2}] [:cite[18]{ln=4}] [:cite[19]{ln=3}] Health care AI must be adapted to local conditions .[:cite[20]{ln=4}] In Nigeria, one medical decision support tool recommended too many lab tests because it reflected high income country practice rather than local needs.[:cite[20]{ln=6}] Safe scale up depends on infrastructure and implementation capacity, including electricity, connectivity, devices, training, and affordability.[:cite[21]{ln=2}] [:cite[22]{ln=1}] [:cite[23]{ln=1}] [:cite[23]{ln=3}] So, in this report’s evidence, AI improves health care best in screening, triage, task shifting, and selected decision support tasks , especially where health systems face shortages of specialized workers.[:cite[24]{ln=2}...
