Wysa is an example of a conversational program that offers cognitive-behavioral exercises between visits with a person. It is support, not a therapist, and it is not a crisis service. Someone at immediate risk needs local emergency care or a crisis line, not a chatbot. Health systems that offer a tool like this still need a path to a human.
臨床場景
Outpatient mental health or employee and student programs, used between scheduled sessions, with clear wording that the app does not handle emergencies.

No depression-score change is repeated here. Trial results for digital CBT vary by product, population, and whether a human coach is included.
REACH VET is a U.S. Veterans Health Administration program. A statistical model flags veterans in a very small top tier of risk each month, and a clinician who knows the patient reviews the chart and makes contact. Identification is not a diagnosis of suicidal intent. The program exists to prompt a human conversation and a look at whether care should change.
This is an illustrative composite, not a trial report. A unit feeds monitor alarms through a second layer that withholds repeats already explained by motion, a loose lead, or a value the nurse just acknowledged. The bedside alarm for a new life-threatening rhythm still sounds. The point of the scenario is the governance question: who is allowed to silence what, and how a missed true alarm would be reviewed.
This is an illustrative composite, not a trial report. As the triage nurse types the chief complaint and first vitals, a model suggests an acuity level. The nurse accepts or overrides it, and the accepted level is the one that enters the queue. The scenario is about keeping a human on the decision when under-triage would delay care. No accuracy percentage is claimed, because this entry is not a study.
