OBJECTIVE: To investigate the irrational drug application in medical orders of tradition Chinese medicine injection in Guilin People’s Hospital（hereinafter referred to as "our hospital"）

so as to provide references for further standardizing the clinical rational application of traditional Chinese medicine injections. METHODS:Through the inpatient electronic medical record platform of our hospital

1 000 pieces of filed electronic medical records of discharged patients from Jan. 1 st

2016 to Aug. 30 th

2019 who were treated with tradition Chinese medicine injection（hospital stay>3 days） were extracted

Pareto diagram method was adopted to analyze irrational medical orders of tradition Chinese medicine injection

so that the main factors

secondary factors and general factors were screened out. RESULTS: Of the 1 000 pieces of medical history of tradition Chinese medicine injection

there were irrational medication in 658 pieces（65. 80%）

there were 879 case-times of irrational medication in total

involving 8 types

the top 3 types ranked by cases were respectively inappropriate dosage

improper solvent selection and inaptitude indications

with the constituent ratios were respectively 27. 99%（246 case-times）

25. 82%（227 case-times） and 18. 66%（164 case-times）

which were the main factors after Pareto diagram analysis

the secondary factor was not used alone

the general factors were incompatible drugs infusion without tube flushing

improper drug selection

inappropriate treatment course and repeated medication. CONCLUSIONS: Using Pareto diagram method to analyze the irrational medical orders of tradition Chinese medicine injection and screen out the main factors

secondary factors and general factors

so that clinical pharmacists can conduct real-time monitoring on irrational medication factors

and formulate corresponding intervention measures such as specific reviews of prescriptions to promote the rational application of tradition Chinese medicine injection.
