Automation of parenteral nutrition: impact on process and cost analysis.

The changes resulting from the automation and revision of the production process globally increased annual expenditures by approximately 9.7%. However, automation minimised the risk of misproduction, bag contamination, and led to a more secure production process that reduced risks incurred by the teams. In view of the gain in patient and staff safety (linked to the use of an automated compounding device) the moderate economic impact (<10%) should not deter the automation of PN production circuits.
