RESUMO
Integrated and shared information systems allow obtaining a high degree of information about processes, costs and outcomes, and considerably reducing prescription errors. Assisted electronic prescription, in the setting of total parenteral nutrition, integrated with other hospital databases and with the hospital drugs management system, is a tool that allows increasing patient' safety (by reducing prescription errors), improving quality assistance, improving information systems and information management and the efficiency of used resources. In this work, implementation of an assisted electronic prescription system applied to parenteral nutrition in a hospital and processes reengineering performed in the nutrition setting are described. This implementation was performed by medical staff from the Nutrition and Diet Department and pharmacists from the Pharmacy Department of Ramón y Cajal Hospital using "Nutriwin" computer software. For two months prior and after its implementation, a follow-up of time consumed in the circuit prescription-validation-elaboration-dispensation of parenteral nutrition formulas has been performed. After implementation, treatment orders reach on average 1 h and 15 minutes sooner the Pharmacy Department; by avoiding transcription, a saving of 3 min per nutrition formula calculations is achieved, besides reducing potential errors; elaboration of nutrition formulas can be started on average 1 h and 20 minutes sooner as compared to manual prescription. Besides, the staff that writes down the prescription may know in real time the nutritional profile for each patient in the current episode and the patient's historic. Electronic prescription of treatment orders in this area has represented for our hospital an optimization of the employed resources, a reduction of potential errors that may occur, an improvement in consumption management, and an increase in the whole process quality.
