Hello, infusion nursing is not my primary role but I may be able to offer some insight. I too am a former ER nurse (still work prn) and I now work full-time in research. However, I see 3 clients regularly for home infusion therapy through a homecare company.
To answer your questions:
1. My experience starting lines and handling infusions in emerg made the transition to infusion nursing pretty much effortless
2. I make about $1 less per hour than I make in emerg, mileage, paid travel, small shift dif, no benefits (but I only work 4-8 hours/wk)
3. My clients are super stable. They get an enzyme infusion every 1-2 weeks, that they've been getting for years.
4. A typical visit for me involves visiting the client at their home with my documentation binder and nursing bag. The supplies are shipped to their homes by the homecare company. I show up and start the line, assess the pt, document what needs documenting, run the drug, d/c the IV and go home (or to my real job). I typically do about 30 mins of charting and faxing once I get home.
5. Stress is basically nonexistent, I genuinely like all my clients and we get on well. There is a bit of stress when dealing with my home care company and the bureaucracy within, but that's not really related to the infusion nursing aspect
Hopefully that gives you some idea and a nurse who actually specializes in infusions will chime in!
