The Economic Impact of Clinical Pharmacist Involvement in the Public Procurement for Medicines and in the Drug and Therapeutics Committee

The investigators have performed cost-minimisation analysis and compared the expenses based on the plan for public procurement (without clinical pharmacist involvement) for drugs with the results of public procurement based on the revised plan for public procurement by the clinical pharmacist. The plan for public procurements was based on the 1 year quantity for each medicine used by the hospital in the previous year, based on the latest deliverable prices at the time of extracting the data to workbook for MS Excel program (ver. 2002, Microsoft, Redmond, WA, USA).

The investigators have performed cost-minimisation analysis and compared the expenses for all received requests for medicines to the drug and therapeutics committee (DTC) for a decision in the 1 year period, before and after involvement of clinical pharmacist in the committee work. The expenses were based on approval decisions in the 1 year period for approval time period. The denial decisions were also calculated and reported. The denial period calculated in rationalisation of expenses were based on 1 year treatment period.
