Karoline, amk brings up a good point. It will just have to be a question that you ask in your interview as to what type of acuity they are expecting to put in the CDU and what happens if a patient starts to turn sour.
In our facility, we have strict rules about who can and cannot come to the CDU. For instance, absolutely no ventilators, no unstable patients, no comabative or agitated patients, no one-to-one patients. Plus if a patient gets worse, they go right back to the ED promptly.
I would ask the interviewer what kind of patient population they expect, what would happen should a patient suddenly worsen, who would be the medical person in charge (ie, will there be a doctor or NP covering patients in this unit or will it be each patient's own PMD). Also ask if they have written guidelines yet for this unit and if you may look at them.
Each place is different as to how its CDU is run so I think it is worthwhile to go to the interview and check it out.
Good luck with the interview and keep us posted! Jeanne
