Abstract: OBJECTIVE To reduce the medication errors of pharmacy intravenous admixture services(PIVAS) medication errors in hospital by developing the strategies. METHODS The healthcare failure mode and effect analysis(HFMEA) method was used to analyze the failure mode of workflow and assess their risks in PIVAS of Children's Hosptial of Shanxi Province, and the reasonable control scheme was proposed. The implementation effect was evaluated by comparing the rate of medication errors and the value of risk priority number before and after the implement of HFMEA. RESULTS After the implement of HFMEA, the incidence of errors in PIVAS of the author's hospital was decreased significantly(P<0.01). CONCLUSION HFMEA is used to prevent and manage risks in all aspects of PIVAS workflow, which can effectively reduce the medication errors in work and promote the safety of children's medication.
