TPN Assistant Overview Print E-mail

TPN Assistant© is a clinical suite of programs tailored to help physicians write Total Parenteral Nutrition (TPN) orders for distinct patient age groups. These groups include neonates, pediatric patients, and adult patients. Each group has a unique method and set of clinical rules around ordering TPN and the modular design of the program allows all or just one of the programs to be used based on the hospital’s needs.

TPN Assistant© is a web based asp.net application that is hosted on a hospital’s intranet and uses a Microsoft SQL Server© backend as a data repository. The application can be accessed by anyone on the hospital network with a logon to the TPN Assistant program regardless of location. Neonatal Assistant© address the unique needs of writing a difficult nutrition order for a premature infant. The challenges in creating and compounding a neonatal order include complex calculations, illegible handwriting, calcium-phosphate solubility issues, osmolarity issues, and transcription errors while retyping the order into a compounding program. Neonatal Assistant© addresses all of these issues to ensure the patient gets the most clinically appropriate order with numerous safety checks as well.

Pediatric Assistant© provides the same features as Neonatal Assistant©, but with the clinical algorithms setup for pediatric patients between 1 and 18 years of age. Order dosing from the physician’s perspective is per kg and the program converts the input into percentages and per 100ml quantities for compounding purposes. One of the biggest advantages of the program is that it can interface directly with the BAXA compounder eliminating the need to reenter the TPN information into Abacus™. The software can also port the TPN order via SFTP to CAPS® for systems that utilize offsite compounding services.

The Adult TPN Assistant© was written for sites that like to utilize the compounder interfacing for all orders regardless of complexity to improve efficiency and reduce pharmacist time spent reviewing TPN orders for clinical appropriateness and reentering them into a compounder software program.
