A 45-year-old man, admitted with DKA at 9 p.m. Sugar 480, ketones 4+, pH 7.18. The on-call resident starts insulin at 6 U/h, sends an ABG at 11 p.m., orders hourly capillary blood glucose, and writes the orders into the patient's chart.

At 1 a.m. she is pulled into a code in the next ward. By the time she returns it is 2:14 a.m. and the night handover is starting.

This is the moment ward work usually fails. Twenty-eight patients to summarise in eight minutes. The DKA patient's 11 p.m. ABG hasn't returned yet. There is no field on paper to capture "pending lab — will return around 3 a.m. — alert me if pH falls further."

In Medows the handover for that patient had auto-composed itself from the shift events:

Bed 16 · 45/M · DKA Now: Insulin infusion 6 U/h, hourly CBG, K+ replacement in IV fluids. Pending: 11 p.m. ABG awaiting result — alert if pH worsens. Repeat ketones at 03:00.

The receiving doctor saw the line at 2:14 a.m. The ABG returned at 3:08 a.m. with pH 7.09. He caught the worsening. By 3:30 the bicarbonate conversation had happened with the senior. By 5 a.m. the trend was reversing.

If the line had been a head-note in the outgoing resident's memory, the next blood gas would have been the 8 a.m. routine. Five hours later. In DKA at pH 7.09, five hours is the difference between a turn around the corner and an ICU transfer.

The point of writing this is not the heroism of catching it. The point is the automaticity of the catch. Nothing about the case required a hero. The handover had captured the pending lab because the system was holding the patient's state across the shift change. The receiving doctor noticed because the line was structured ("Pending: …"), not buried in free text.

This is what an automated handover looks like when it works: invisible until it's the thing that prevents the next mistake.
