I suggest looking for companies that do private-duty nursing rather than case management. With private-duty work you spend your 8-12 hour shift in the patients home taking care of one individual. You'll get more hands-on time with your patients and I've found the atmosphere to be rather enjoyable. I started out after getting my ADN with Edelweiss Home Health Care. They used to specialize in pediatrics, though they have a few adults now I believe. You'll gain a lot of skills with this type of environment as many of the pediatric patients are technology dependent (trachs, vents, G-J tubes, feeding pumps), working nights are typically quiet so you have time to read books, etc while monitoring the patient. If you work during the day you interact with the families more as well as with OT and PT and learn skills to help in the patients development. Also, they typically only assign you to 1-3 patients at a time so you really get to know your cases. The pay is fair. Upfront it may seem a little challenging, the scheduling system is a little weird sometimes, they will pay for the classes you need to take to learn about the vents, etc, but they won't pay you for your time in the class. Once you get through orientation though it's a pretty nice gig.
I believe Bayada also offers a similar type of work, but I am not as familiar with them. If you have any other questions please feel free to ask.
