I agree completely with what was said before. I wanted to highlight the specific challenge of running a center that creates TPN.
In the US there is a lot of discussion regarding compounding centers because they are extremely risky. Centers that focus on TPN have also had examples of quality control problems that led to many patient deaths. I absolutely understand all of the advantages, but you will need someone with expertise to create the facility and be focused on the continuous quality control and training of the staff that will run the facility. It’s certainly possible to accomplish this, but there are many, many risks to creating such a center.
