OBJECTIVE:To improve hospital dispensing system and reduce dispensing error. METHODS: The causes of 65 cases of dispensing error occurred in outpatient pharmacy were analyzed by employing total quality management (TQM) method from 5 aspects: human,machine,material,method and environment. RESULTS: Among the 5 kinds of factors,the "human" factor took the lead,which accounted for 83% of the dispensing errors. Quality control carried out aimed at the primary factor contributed to the reduction of dispensing error cases,down from previous annual average 16 cases to 1 case of the first 10 month in 2008. CONCLUSION: TQM method contributed to the reduction of dispensing error rate in hospital outpatient pharmacy.

Objective To investigate the effects of antioxidant on the fish oil cream and to enhance its stabil-ity.Methods The fish oil cream containing different antioxidant such as vitamin C,vitamin E,EDTA -2Na were prepared.The content of vitamin A with 6 months acceleration test and 12 months after long -term test were deter-mined by HPLC.Results Antioxidants had significant effect on the vitamin A content in fish oil cream,the sequence that antioxidants enhance the stability of the fish oil cream was as follows:VE +Na2 S2 O5 >VC +Na2 S2 O5 >VE +ED-TA -2Na >VC +EDTA -2Na >VE ﹥ Na2 S2 O5 >VC >EDTA -2Na.Conclusion The fish oil cream with antioxi-dant have favorable stability,composite antioxidant is better than single antioxidant.
