Keeping patient safety a top priority, a new technology helps pharmacists and technicians prepare a more accurate dose of medication. DoseEdge TPN (total parenteral nutrition), manufactured by Baxa Corp., when used in combination with calculation software and a compounder, provides automated support for TPN dose preparation, documentation, and inspection. When done by hand, TPN compounding is subject to human error. However, DoseEdge reduces the chance of error, because it can catch problems in the workflow and processes. The system also includes a bar code verification of ingredients, automated volume calculations, and photo evidence of correct measurement and injection. In addition, new security features let the user track doses via scanning outside the pharmacy.
