Abstract
This study aimed to analyze pharmaceutical purchasing capability of public hospitals using the
Pharmaceutical Acquisition Capability (PAC) Approach. The 2010 purchasing data of public hospitals
was provided by the Drug and Medical Supply Information Center (DMSIC), Ministry of Public Health. the data analysis was done by selecting the drug items that were submitted to DMSIC by more than 3
public hospitals. Total 31 items were included in this study that were categorized into 5 pharmacological
groups i.e. 1) HMG-CoA-reductase inhibitors or Statin, 2) Proton pump inhibitors (PPI), 3) Blood-glucoselowering
drugs, 4) COX-2 selective inhibitor, and 5) Combination of Statin. It was found that a number of
markets held Gini coefficient higher than 0.500. This could be interpreted that purchasers in this market
could buy the product at lower price suggested by PAC-DSS. In addition, high average PAC was also
found in the market with multiple sellers, leading to the recommendation that purchasers could easily
negotiate their price in this market. The study estimated that if hospitals had purchased 31 drug items at
PAC-DSS suggested prices, these public hospitals as a whole would have gained 77 million baht saving.
The standardization and development of data entry system is strongly recommended for better outputs.
The future study on additional invention of feedback information is also suggested to benefit users.
