Also, case management for insurance co's. Case management can be done in and out of hospitla though, and what it is is to follow a pt, and coordinate their health needs, in the insur co, a CM may set-up the home care a pt will get, arrange for DME delivery to the home, arrange for transportation, or arrange for a pt to be seen by a specialist. Some nurses in insur co's precert care, or oversee utilization of hospital beds.
Another one is school nursing.
Occupational health nursing; assessing the responsibilities of what each position entails, how injuries might occur, and taking measures, re educating employees on how to avoid injury and also treating injuries and illnesses as they arise.
