AI in care, fast
Yvonne Cook agreed to take part in an NHS Grampian evaluation in Aberdeen, Scotland, in May 2023 after an artificial intelligence system was being evaluated as an aid in reviewing mammogram images. The AI system flagged a small abnormality, and additional imaging and a consultant confirmed that it was breast cancer, which Cook then received medication, surgery and radiotherapy for. Diana Hurtado, a 30-year-old Uber driver in South Florida, described stroke symptoms to ChatGPT, which warned that a stroke was possible and urged her to call 911.
Hurtado sought emergency care, where doctors confirmed that she had suffered a stroke, and she subsequently underwent brain surgery and rehabilitation. The NHS Grampian evaluation involved 10,889 women, and researchers reported that using AI alongside the screening process increased cancer detection by 10.4%.
Time, detection, and limits
The Sweden trial described in the article assigned nearly 106,000 women to either AI-supported mammography or standard screening, where two radiologists read each image. The AI-supported approach detected a greater share of cancers present at screening, at 80.5% compared with 73.8%, while both approaches had the same reported specificity of 98.5%. The article said the study does not establish that AI reduced deaths from breast cancer, but it offers substantial evidence that AI can help radiologists perform the crucial task of finding cancer.
The article also said a chatbot’s response cannot establish a diagnosis, and it told people with possible stroke symptoms to call emergency services immediately. Hurtado told NBC 6 that the warning helped her act before she lost more time, and the article framed the two cases as different uses of AI.
AI health benefits push
Corridor raised a $25 million seed round led by Bain Capital Ventures to use AI agents for small business health benefits, pairing human advisers with AI agents that take on repetitive back-office tasks. Corridor’s AI agents check whether a doctor is in a plan’s network, schedule care, and relay updated insurance information to providers, and the company said about 80% of small businesses choose their health plan in the fourth quarter. Insurance Business described how investors are funding AI-native benefits platforms, and it said Corridor routes administrative work of quoting, placing and servicing plans through AI agents with licensed advisors handling client-facing strategy.
Insurance Business also quoted Bain Capital Ventures partner Ryan Kim saying, "Administrative cost is the part of a premium that buys no care, and insurance distribution is where much of it accumulates because the work is still manual," and it added that "Corridor's agents do that work." Nara Health raised $14 million led by Khosla Ventures to expand an AI-native health benefits administration platform that had processed more than $600 million in medical claims for over 25,000 members.
