Abstract: Objective To analyze the factors which cause the adverse drug reaction/event(ADR/ADE) induced by out-patient injection, and to explore how to control ADR/ADE. Methods ADR/ADE cases collected from the clinic injection room in our hospital have analyzed. Results There were 56 kinds of drugs related with 371 ADR/ADE, and antibiotics were in the first place(185 cases, 49.9%), followed by the Traditional Chinese Medicine injection(88 cases, 23.7%). The shortest time between infusion and ADR/ADE occurrence was five minutes, but 160 ADR/ADE cases (43.1%) occurred in 10~30 minutes after injection, so it is an important stage to inspect ADR/ADE. Lesions of the skin and the appendants is most. Conclusion To reduce the incidence of ADR/ADE induced by out-patient injection, our hospital should establish a strict ADR monitoring system, and take some preventive measures.
