Four minutes, no narration, one patient. Eleanor Brooks, 79, from the pharmacy desk before she arrives to the pump at her ICU bedside. Nine hand-offs. In every one of them, today, the person doing the work sees a piece of the patient and reacts to the piece they can see. Ai MedAgent™ reads along the whole way: the EHR over HL7 and FHIR, the pump and the monitor through OpenBedside, the public drug data that has been sitting there free for years. At each hand-off it reasons over everything so far and proposes. A clinician approves every change. That is the design, not a disclaimer.
What is real: the reasoning, which runs today at aimedagent.net. What is not: Eleanor, who is synthetic, and the screens, which are drawn. Not FDA cleared. Patent pending. A proof of concept, not a product.
This readership will check the numbers, so here they are. The norepinephrine bag is 4 mg in 250 mL, 16 mcg/mL, and the pump rates are computed for a 58 kg patient. The cefepime adjustment follows the label table for a creatinine clearance of 11 to 29 mL/min.
Does it matter? I think the whole encounter reasoned over at once, local data and public data together, with the pump in the loop, is the piece that forty years of interoperability work never delivered. I am retired, so I am not looking for a job. I am looking for a home for the work: an organization heading this way or one that would rather license the IP and build it properly.
