Establishment of clinical decision support system for physician order of total nutrient admixture / 中华临床营养杂志

Objective:To establish a design of a clinical decision support (CDS) system ithin the computerized physician order entry (CPOE) system to ensure the correct prescribing of total nutrient admixture (TNA) orders.Methods:An improved new workflow was designed in consideration of both the TNA and doctor's prescription work flow. An exclusive CPOE interface for TNA physician order was established, within which a CDS mode was also created. When individual components of the TNA physician order are inputted, automatic calculation is performed through CDS to determine whether patient's clinical nutritional needs and pharmaceutical process requirements are both met. The generated feedback is presented directly to the prescribing clinician in the interface. Through rationality assessment of physician orders and real-time alarm feedback for inappropriate orders, the system can achieve pre-review of TNA orders as well as the education for clinicians on parenteral nutrition order prescription.Results:The usable drug catalog is created at the back end of CDS, thus precluding unreasonable medical orders of therapeutic drugs in TNA regimens. The background CPOE auxiliary support system for parenteral nutrition can correctly evaluate the reasonability of the carrier solution and provide real-time feedback in the CPOE interface.Conclusion:The establishment of the CPOE auxiliary support system eliminates the possibility of unreasonable component proportions and admixture with other therapeutic drugs in TNA orders to ensure TNA orders with rationale component proportion and good compatibility and stability, ultimately satisfying patient's daily calory need and guaranteeing medication safety of parenteral nutrition.

Evaluation of the Efficiency of a Computerized Physician Order Entry System Serving Pediatric Patients who Visit the Emergency Ddepartment

PURPOSE: The purpose of this article was to evaluate the efficiency of an automated prescription program serving pediatric patients who visited our emergency department. We expected that the program would reduce pediatric patient prescription errors and shorten the length of stay in the emergency department. METHODS: We developed the computerized physician order entry system to serve the pediatric patients visiting the emergency department and recommended that the emergency medicine residents use this program. We compared the rate of error as it affected prescription dosage and length of stay in the emergency department, before and after the program was deployed. We also performed a survey with 20 emergency medicine residents that have used the program. RESULTS: Of the total number of prescriptions filled, the number of prescription dosing errors observed was 40(4.5%) before and 22(2.8%) after the program was deployed. The results of the survey revealed high system usability and satisfaction. However, the length of stay in the emergency department was not affected. CONCLUSION: The computerized physician order entry system for pediatric patients visiting the emergency department was effective in reducing prescription related medical errors.
