Summary

OpenAI's Head of Business Finance, Chengpeng Mou, reported on April 5, 2026, specific usage statistics for ChatGPT in the U.S. related to healthcare. The data indicates approximately 2 million weekly messages concerning health insurance. Furthermore, about 600,000 weekly messages classified as healthcare-related originate from individuals residing in "hospital deserts," defined as being more than a 30-minute drive from the nearest hospital. A significant finding is that 70% of these healthcare-related messages occur outside of standard clinic operating hours.

Key takeaway

For healthcare providers and digital health innovators, these ChatGPT usage patterns highlight a significant unmet need for accessible health information and support, particularly outside traditional clinic hours and in geographically underserved regions. You should consider developing AI-powered solutions that offer 24/7 assistance and target populations in "hospital deserts" to improve health equity and access.
