OBJECTIVE： To provide reference for further evaluating， improving and ensuring the smooth implementation of centralized drug purchase and use pilot organized by the state. METHODS： By using the methods of literature research and investigation， monitoring purpose， monitoring contents （including supply guarantee， use guarantee， quality guarantee and cost control） and monitoring methods of Monitoring Programme for Centralized Drug Purchase and Use Pilot Projects Organized by the State were sorted， summarized and analyzed so as to put forward the suggestions.  RESULTS & CONCLUSIONS： The monitoring purpose was to control the procurement phase from two aspects： policy guidance and information monitoring. In the contents of monitoring， monitoring indicators were set up for supply gurantee from two aspects of production and circulation. The former included seven indicators of production inventory， stop and resume production， source and supply and price of core raw materials and accessories， and the latter included two indicators of channel inventory and days of repayment. For use gurantee， selected drugs， original drugs in the item of generic name， other drugs in the terms of generic name and substitutable drugs of the same kind were monitored in respects of monthly purchase price， purchase quantity， purchase amount， accumulative purchase quantity， accumulative purchase amount， prescription quantity. Quality gurantee indexes included drug stability （batches and projects of unqualified drugs）， safety （ADR， severe ADR， public complaints and reporting incidents） and effectiveness （number of drug-change patients and number of secondary drug-change patients）. For cost control， the monthly drug quantity and cost of selected drugs， original drugs in the item of generic name， other drugs in the terms of generic name and substitutable drugs of the same kind were monitored； original drug cost （for original drugs in the term of same generic name）， the cost of other drugs and the reimbursement ratio of last year’s medical insurance （for other drugs in the term of generic name） were compared with the same period of the previous year， in which the drug quantity was calculated by DDDs. The monitoring methods included three-level monitoring by the national organization office for the contralized procurement and useage of pharmaceuticals， “4+7” city joint procurement office and pilot area， and regular monthly reporting and timely feedback of monitoring information. Monitoring information submission was mainly in the form of standardized report format （filling by manual in monthly， e-mail submission） and automatic system submission （every day， other pilot cities and Shanghai Joint Purchasing Data Exchange Platform established data interface for automatic submission）. According to the fact， author put forward the suggestions to improve the monitoring contents， such as adjusting the measurement standard of inventory turnover days， defining the statistical caliber of purchasing quantity and price monitoring， distinguishing the specifications of pharmaceutical preparations and packaging， defining the every drug DDD value in monitoring range， and so on. At the same time， the author suggests optimizing the reporting mode of monitoring information， interworking the purchasing platform with medical insurance information， and integrating drug supply chain information from manufacturing enterprises， distribution enterprises， medical institutions to patients， providing cross-provincial trading services， etc.， make them play a greater role in drug procurement management of the National Healthcare Security Administration， rational use management of drug by the Nation Health Commission of the People’s Republic of China， and drug traceability management of the National Medical Products Administration.
