- Accelerating Research: AI can speed up the drug discovery process by identifying promising drug candidates and predicting their effectiveness.
The Big Three Enter Healthcare — But Patients and Practitioners Remain Cautious
In January 2026, OpenAI launched ChatGPT Health while Anthropic introduced Claude for Healthcare, marking a major escalation in AI competition within medicine. Google, notably, pulled back by removing AI Overviews from medical queries, signaling caution about the reliability of its outputs in clinical contexts. A research review by Osnat Bashkin of Ashkelon Academic College, covering 38 studies from 13 countries, found that more than 75% of patients recognize worthwhile benefits in healthcare AI, yet patients also harbor understandable mixed feelings about its use. Anthropic's own research into Claude's 'functional emotions' has added another layer, revealing that understanding AI psychology is not optional for safe healthcare deployment.
Data Gaps, Privacy Risks, and the Problem of Fabricated Medical Images
Despite growing investment, diagnostic AI continues to face significant obstacles: data gaps and privacy risks weaken performance, and poor diagnostic data limits how well healthcare AI can learn, according to EOS Intelligence. Trust remains a barrier among both clinicians and patients, slowing adoption even as radiologist shortages create urgent demand for AI-assisted diagnostics. A separate but equally troubling issue has emerged in biomedicine: The Register reports that bad AI-generated images are a growing problem, with fabricated or distorted visuals circulating in research communities and practitioners yet to figure out how to mitigate the risks. These failures underscore that AI's promise in healthcare is far from self-executing.
Healthcare's Digital Acceleration: Lessons from the Pandemic
The COVID-19 pandemic fundamentally reshaped healthcare delivery, pushing doctors toward online consultations and bringing remote fitness and monitoring tools into mainstream use, as Kritika Malhotra documents in her analysis of tech's role in healthcare.
