I’m not sure I believe it. You would be evaluated and either discharged or committed to the psych ward within the first day, you wouldn’t be kept in emergency in-patient.

I can see a couple scenarios:

1. The ED is so backed up that it took two days to evaluate the patient at all
2. The patient doesn’t understand the difference between being in the ED and getting admitted/transferred to a separate psych ward and just said “I was in the ER for two days”
