First of all welcome to allnurses. You will find some stickies on the home health forum concerning your questions. Also you can glean some info from reading the various threads in home hlth, agency, and hospice. The biggest thing in your transition may be overcoming a sense of inadequacy because you are going there by yourself. Remember that you always have resource people back at the office to consult when you run into problems. There are also some CEU courses in this area that you might want to consult:
www.WesternSchools.com or 1-800-438-8888 has a 66 contact hour course on palliative practices and another 30 contact hour course on home health, both of which you might find useful, even if you don't take them for the CEs.
The best advice I can offer, in general, is do not be too hard on yourself concerning your learning curve, and do not be afraid to ask questions. Good luck in your new area. I hope you find your new position satisfying.
