A night shift
Night of 4 to 5 November 2026, Val-Clair Hospital. Yann Berger, technician, is running the blood bank alone.
Fictitious patients, numbers and analysers. Screens recreated from the application.
02:14 The request arrives from Jade.
In the emergency department, Paul Vuillemin, 47, may need a transfusion. JadeIH receives the urgent order, acknowledges it and puts it at the top of the list; the banner counts the emergency.
02:15 Unknown to the blood bank.
JadeIH searches for the patient by Jade number, then by AHV number, never by name alone, and does not find him. Yann confirms: the record opens with no validated group, showing the emergency procedure from the Swiss guidelines.
02:20 The analyser link goes down. Nothing is lost.
At 02:16, the whole tube was sent to IH-VCC-1, routed per test and per site. The outage shows on every screen; the middleware holds the messages, and everything resumes at 02:24.
02:31 Results come back, well by well.
IH-VCC-1 returns the group, the reaction of each well and the card image: anti-A and anti-D hold the cells at the top of the gel; on the plasma side only the B cells agglutinate. A RhD positive, antibody screen negative.
02:33 Urgent technical validation: the result goes out immediately.
Yann types in the confirmation code: the results go to Jade, flagged as not biologically validated. The request stays in the biological queue: a single tube does not make an established group.
03:05 A second tube, collected at another time.
A new tube is collected in the emergency department; at 03:22, IH-VCC-1 returns the same group. On the same tube, JadeIH would have warned: “Same sample as the 1st determination: does not count as the 2nd.”
07:30 In the morning, another person validates.
Dr Hélène Vautier neither entered results nor validated technically: JadeIH lets her validate both requests. The 2nd confirms the group, and the card loses its PROVISIONAL watermark.
07:41 Received in Jade, not just sent.
The validated results go back to Jade as ORU^R01. JadeIH then queries Jade and writes it to the request log: the loop is closed, and you know it.
