Six named AI initiatives at real hospital-system scale (Timpani staffing/scheduling live at 130+ hospitals; Google-built Nurse Handoff; ambient documentation pilot; GE HealthCare maternal-fetal integration). Labor friction is real but far earlier-stage than Kaiser: NUHW protested the Palantir partnership behind Timpani (04-18 Frist Gala) over centralized staffing decisions and surveillance-vendor data concerns, but no DMHC-equivalent complaint, hearing, or strike has surfaced. Watch: whether the Palantir dispute escalates the way Kaiser's did; any HCA public response; whether AI ever appears in an HCA SEC filing (it currently doesn't). A separate securities-fraud probe (07-14 guidance cut, payer-mix driven) is confirmed unrelated to AI — track independently, don't conflate.
