I hate to be a doomsday person, but I worked a short contract in home infusion, and I would never work full time in that capacity. I was very relieved to leave.
All one needs is a couple of disgruntled employees and you would faint if you saw what I saw where I worked --and that was almost a decade ago!

NECC is listed on the net as having 60 employees! Very difficult to supervise that many IMO. Typically only a very small number are licensed pharmacists at home infusion or compounding pharmacies.
There are licensed infusion technicians.

It could very well be that things like this were going on for a while and just never caught. With all the many shortages going on now in the past 2-3 yrs on so many drugs, including injectables, compounding pharmacies are filling that niche more and more.

There are frequent procedures done to test the air quality and cleanliness. They even run cultures periodically. All one needs is some mess-up at this task, and mayhem can result.

I agree it is very sad and very scary too.
