In the period from January 2010 to December 2010, three different forms of contract-bidding for drug supply to clinics were employed: Concentrated contract-bidding took place in 40 areas (63.5 percent), the representative method did in 10 areas (15.9 percent) and the single contract-bidding in 13 areas. The choice of contract-bidding methods was related to the management model of medical systems in question. All the national/central hospitals prefered single bidding, while those of provincial and district level primarily applied either representative or concentrated methods. Only private clinics without taking part in medical insurance practised self-supply of drugs through single contract-bidding or direct purchasing drugs based on bidding result.s of public hospitals. Concentrated bidding made it easier for national management to create fair competitive environment with the participation of many supplying units, select the pharmacies of the best quality, and assure the price consistence throughout the area. Yet, many disadvantages occured in drug supply bidding, such as time consumption, inconsistency of criteria for selecting.
