Case Study
How a hospital put three AI agents into live clinical operations, voice, vision, and knowledge, using one platform, running inside a working hospital.
Three FosterX agents in daily clinical use: one listens to every patient call, one writes the doctor's notes, one watches the medical devices and answers the nurses. All three went live in a 30-day deployment to production. The modelled numbers, show a comparable deployment in the UK return cost in savings of about 5 months, on saved staffing alone, before a single extra patient is counted.i
THE EXPENSIVE STATUS QUO
Three streams of non-medical admin work treating patients
This hospital had three expensive streams of work that really had nothing to do with treating patients, and all were being handled the hard way.
Patient calls came in and were recorded, then mostly went unheard. A person can realistically sample five to ten percent of inbound calls for quality, tone, and red flags. The other ninety percent are a blind spot. A distressed caller, a confused discharge instruction, a complaint forming in real time, most of it never reaches a supervisor until it has already become a problem.
Doctors spent a large part of their day writing rather than treating. The UK benchmark for clinician documentation is about 15 hours a week for a consultant, and close to five of those hours spill into personal time after the clinic closes (Nuance and Ignetica NHS survey, 2022). The peer-reviewed time-and-motion work puts roughly two hours of screen and desk work against every hour of direct patient care (Annals of Internal Medicine, Sinsky, 2016). That is medical expertise capacity going into a keyboard.
Nurses carried the medication schedules, the device readings, and the protocol lookups in their heads or on paper. When a nurse must remember which infusion is due, walk to a monitor to read it, or stop to look up a dosage, two things happen. Care slows down, and the margin for a medication error widens. In the NHS, medication errors cost an estimated £98.5 million a year in avoidable harm alone, and far more on the wider basis (BMJ Quality and Safety, 2021).
Three cost centres, three risks, and not one of them was getting cheaper on its own.
THE AGENTIC SOLUTION
FosterX deployed three agents. Each one perceives something in the hospital, decides what it means, and acts. The point worth holding onto is that these are three different senses, voice, vision, and knowledge, running on the same platform.
The IVR Analyzer listens to every call
It perceives the full audio of all inbound patient calls, not a sample. It runs a 20-point cognitive audit on each one, scoring tone, urgency, confusion, distress, and satisfaction, and it decides which calls a human need to see. When it flags one, it acts by sending a WhatsApp alert to the supervisor while the issue is still live. This is the work a call-quality analyst would do, except it covers 100 percent of calls instead of the five to ten percent a person can reach. That is the cost it removes, and the coverage gap it closes.

The Ambient Medical Scribe writes the notes
It perceives the consultation as it happens, listening to the doctor and patient. It decides what belongs in the record, structuring the conversation into a proper SOAP note, and it acts by writing that note into the EHR. The doctor reviews and signs. Roughly eight doctors use it today. It gives back the documentation time that was leaking into evenings. The UK does not run human medical scribes at scale, so the honest comparison is the US scribe market, where a human service runs $14,000 to $42,000 per doctor a year. The agent does the same job at well under five percent of that, which is why the real value to a UK hospital is the clinician time it returns rather than a headcount it replaces.

The Nurse Assistant watches the devices and answers the questions
This is the computer-vision agent. It perceives 7-segment displays on medical devices through a camera, reads the numbers a nurse would otherwise walk over to check, and decides when a medication or a vitals check is due. It acts two ways: it pushes proactive reminders, and it answers protocol and dosage questions on demand by retrieving from the hospital's own knowledge base. It does not replace nurses. It gives a slice of every nurse's time back and takes one common path to a medication error off the table.
