Call is going to vary alot from one hospital to another. One hospital in our system has one PACU nurse on call on weeknights and a couple on weekend days (scheduled cases) and one or two on weekend nights. We get minimal trauma cases, they go to one of the two large hospitals. My hospital is small (3 OR/3 PACU beds), we only have 3 PACU nurses. When I started, OR still did their own call case recoveries. After a while, they put PACU nurses on call on weekends only. We each take the whole weekend. OR still does their own weeknight recoveries. OR Nurses have to live within 30 min of the hospital. PACU nurses don't have a specific distance because usually we have plenty of time if know about the case before it starts. As far as how call is assigned, I could let the manager make up the call schedule, but I draft it myself, so we can talk about it before we give it to the manager. She likes not having to make up the schedule. We get paid a small amount for being on call, then get paid time and a half for cases, min two hours paid.
