FAQ
What is ChatGPT Health and how is it different from general chatbots?
OpenAI’s dedicated mode aims to confine health chats in a more private context, with options to connect records and apps. Clinicians quoted see both risk from hallucinations and benefit from guardrails and provider-side tools [1].
How does the FDA’s January guidance affect AI wearables and CDS?
Low-risk wellness devices and clinician-reviewable CDS are generally outside active device oversight, while diagnostic or therapeutic claims remain regulated. The approach is risk-based and clarifies existing policy [9].
What did Vista AI’s funding aim to accomplish?
Scale an FDA-cleared automated MRI platform from cardiac to brain, spine, and prostate, plus remote scanning services to address technologist shortages and backlogs reported at early sites [5].
How strong is the clinical evidence for AI assistants in postoperative care?
An RCT of a GPT-4–based WeChat agent showed faster responses and short-term functional gains vs usual care, with similar outcomes by 6 months and slightly lower accuracy than physicians [14].
Can wearable-derived models predict cardiovascular or metabolic risk?
Yes, studies reported associations between AI ECG-age and AF presence/burden [13], and a CGM foundation model that improved outcome prediction and long-term risk stratification beyond HbA1c [18].
What does Anthropic’s Claude for Healthcare add for enterprises?
HIPAA-ready access to CMS coverage, ICD-10, NPI, FHIR skills, and life-sciences connectors like Medidata, ClinicalTrials.gov, and Open Targets to support prior auth, claims, protocol drafting, and trial ops [19].
