OBJECTIVE:To promote the informationization and standardization of narcotic drug management so as to enhance the level of pharmacy management. METHODS:The function of intelligent narcotic drug management cabinet and its application in our hospital were introduced. The application effects were evaluated by comparing the indexes in 1 month(or 1 quarter)before and after the adoption of the cabinet. RESULTS:The intelligent narcotic drug management cabinet used in our hospital had such func-tions as login,getting drugs,adding drugs,expiration date management,inventory query,update,shifting of duty,record and da-ta processing. After the adoption,the inventory decreased by 35.2%,turnover rate increased by 53.4%;the time of applying for and registering narcotic drugs by the keeper of secondary warehouse respectively shortened by 84.1%(13.2 min vs. 2.1 min) and 88.9%(10.8 min vs. 1.2 min);and the incidence of external errors reduced from 3 times to once,an decrease of 66.7%. Mean-while,high integration of space improved the overall image of the pharmacy and the automatic pharmacy was constructed on a cer-tain scale and in a systematic manner. CONCLUSIONS:The application of intelligent narcotic drug management cabinet to the out-patient pharmacy can reduce the inventory cost,increase work efficiency and the safety of drug use,and make the narcotic drug management more standard,scientific and sophisticated.
