Parenteral nutrition(PN)prescriptions usually consist of a large number of drugs,resulting in the concerns of compatibility between drugs and rationality of nutrient ratio,which will affect the stability,compatibility,safety and effectiveness of clinical application of nutrient mixture.Improper prescription is likely to cause serious harm to patients,rendering prescription review necessary to ensure drug safety.In order to further standardize the rationality of PN prescriptions and strengthen prescription review,Tianjin Medical Association Branch of Parenteral and Enteral Nutrition held a discussion with a panel of nearly 100 domestic experts in related fields to elaborate the keys of PN prescription review.The discussion was based on existing evidence in evidence-based medicine and pharmaceutical science,and covered indications review,drug selection,cross-component compatibility,and stability of nutrient solution.Eventually,11 questions and 24 recommendations were put forward to form the Expert Consensus on Clinical Parenteral Nutrition Prescription Review,aiming to inform and facilitate safe,effective,economical and appropriate standard application of clinical PN treatment.
