Venting-Angry about nurse situation

DD is 21 and has rheumatoid arthritis along with other health issues.  She's doing very well now, but still gets a monthly infusion medication for her arthritis.  She sees a rheumatologist at a University hospital.  They have their own pharmacy that sends out the medications/supplies and arranges the nurses that they send out to our house monthly.  

Her infusion for this month was set for yesterday.  At the end of last week they called and said they would no longer be sending out their own nurses but are contracting them out from different home nurse agencies from around the state.  They gave me the name and number of the new company, told me they are experienced with home infusions, the medications etc.  Someone from that company called me a day or so later and told me that Suzy would be out on Monday afternoon as scheduled.  Great.  

Suzy gets here yesterday and is going through the supplies that the pharmacy sent and they had not sent enough of a couple of the items.  So she could not do the infusion yesterday.  She called the pharmacy who said they would send a courier that evening to send the rest of the items.  Meanwhile she would come back this morning to do the infusion.  The items did arrive last night.

This morning a totally different nurse shows up and she seems to have no clue what she is doing (and no social skills either).  Since dd is 21 and I am working from home, I was upstairs working.  I came downstairs a few minutes after she arrived to see it's a different nurse. One who seemed to think she was infusing antibiotics.  Dd told her no, it's an infusion med for RA.  She was totally confused on how to mix it up. She was reading the orders and seemed so confused.  So I called her company and told them she didn't seem to know what she was doing.  They said they would call her.  I'm upstairs trying to work and dd is freaking out.  I called back again as they never called her.  They asked to speak to her and explained things and she said she understood.  I went back upstairs.  DD then text me as the nurse still seems unsure of things.  Back down I went.  We had to tell her that she needed to take dd's temperature and blood pressure.  She said she would do that while the infusion was happening. No it needs to be done before as if she has a fever, she can't get these meds.  So she did that.  I went back upstairs.  DD later said she never washed her hands, didn't wipe down the vials or iv tubing connectors with alcohol swabs. FYI I don't know why dd didn't say anything, she's usually very good at self advocating, but she was kind of nervous working with a new nurse and her anxiety is up for a few other reasons.  But then to top it all off the infusion is supposed take about a half hour.  But this nurse ran it through at a different rate so it only took less than ten minutes.

I have called dd's doctor, the pharmacy that used to send out the nurses, but now contracts out and the new home health company to register my concerns.  I just can't believe the incompetency.
