AI-Powered Patient Navigators
An AI-powered virtual patient navigator, trialed among under-screened patients in New York, doubled colonoscopy completion rates compared with usual care, with high acceptability. This highlights AI's potential to improve screening adherence, especially in underserved populations, by providing personalized guidance and support.

Online Risk Stratification Tools
The Fatty Liver Foundation in the U.S. offers an online AI-based risk stratification tool, enabling individuals to input basic health data and receive guidance on their likelihood of undiagnosed fibrosis. This promotes early medical engagement and empowers individuals to take proactive steps in managing their liver health, broadening the reach of screening beyond clinical settings.

AI for Linkage to Care
In Spain, health authorities used AI-powered text mining of EHRs to flag previously diagnosed HCV patients lost to follow-up, enabling targeted re-engagement. Similar NLP algorithms in the U.S. identified HIV/HCV co-infected individuals not receiving therapy, facilitating targeted case management. These tools are crucial for achieving WHO elimination goals by improving retention and ensuring timely treatment.

Digital Epidemiology: Yelp NLP Project
A landmark initiative by the New York City (NYC) Department of Health demonstrated the utility of mining Yelp restaurant reviews using NLP algorithms to detect foodborne illness signals. Over 9 months, 129 potential cases were identified, with only 3% overlapping official reports. This shows AI's value in capturing signals from otherwise unmonitored population segments, augmenting conventional surveillance, and increasing sensitivity to outbreaks.

AI in Mass Screening Programs
In China, mass screening programs for oesophageal and gastric cancer have integrated AI-based image analysis to improve lesion detection and workflow efficiency. One CNN trained on ~8400 oesophageal cancer images detected lesions <1 cm in size – frequently missed by human observers – processing >1100 test images in just 27 seconds. This demonstrates how AI integration significantly enhances early detection and curability in population-based screening.

Global IBD Epidemiology & Resource Allocation
The Global IBD Collaborative used ML clustering to categorize countries into four 'epidemiologic stages' of IBD emergence and spread, identifying regions such as parts of South Asia and Africa where incidence is now rising. This ML-driven analysis confirmed societal westernization consistently precedes IBD emergence, informing policy planning on specialist training and care capacity expansion. Such granular insights enable proactive public health planning for rising IBD burden.

Addressing Health Equity in AI Deployment
Unrepresentative training data can perpetuate bias, leading to underperformance in minority populations. For example, a CRC risk model trained primarily on European populations may underperform when applied to African or Asian populations. To mitigate this, frameworks advocate for bias audits, algorithmic transparency, diverse research cohorts, and community engagement. International collaboration is critical to ensure AI models are adaptable and accessible for resource-limited settings, preventing exacerbation of existing health disparities.
