AI Scheduling Software Is Straining Nurses at America's Largest Hospital Chain
HCA Healthcare's Palantir-built scheduling tool is supposed to save time, but nurses say it ignores their shift requests and leaves units short on experienced staff.
What happened: HCA Healthcare, the largest US hospital chain, has rolled out an AI scheduling tool called Timpani, built with Palantir, at roughly 130 of its 190 hospitals since 2023. Nurses in Florida, Missouri and Texas told Wired the software routinely ignores their shift preferences, assigns too few senior nurses to cover units, and ships schedules with little notice. A former HCA data scientist is suing the company, alleging it deleted data the tool relies on, making it hard to check whether Timpani is actually working as intended.
Why it matters: Nurses say thin, inexperienced staffing on some shifts forces veterans to choose which sick patients get attention first, and that last-minute changes are pushing colleagues to call out or quit. HCA disputes that the tool drives staffing decisions, saying nurse leaders sign off on every schedule. But a 500-nurse union local has filed a grievance over it, and similar scheduling software from Palantir has also caused mix-ups at a separate radiology chain, suggesting the problems may not be a one-off.
How it works, plainly: Timpani runs on Palantir Foundry, a data platform that forecasts how many patients a unit expects and how much staff it needs, then auto-generates a schedule from that forecast plus nurses' stated preferences. HCA says it honors about 99 percent of requested days off and that over 98 percent of shifts mix experience levels appropriately. Nurses counter that getting scheduled on a day off, once rare, now happens to nearly everyone, and that appeals go to a distant Nashville team with no back-and-forth.
The rollout: HCA says it keeps tweaking Timpani based on nurse feedback and that managers, not the algorithm, make final calls. Union leaders say HCA has refused to share details about how the system works, and nurses at a North Carolina hospital say they'll resist its introduction. The tension echoes Palantir's broader push into health care, including a $440 million UK NHS contract that nurses and privacy activists there have also tried to block.
