Drug utilization research was defined by WHO as the study of marketing, distribution, prescription, and use of drugs in a society, with special emphasis on the resulting medical, social and economic consequences. There is lack of information about the use of antimicrobial agents in the ICU at GGGH till date. So we decided to conduct this type of study.

The most common emergency was post-operative 204 (33.38%).The most common prescribed antimicrobial drug group and drug was antiamoebic drugs and metronidazole respectively in 437 (24.04%) out of total drugs prescribed. The numbers of antimicrobial drugs prescribed per patient were 2.97. 68% drugs were prescribed from WHO and national EML list. Total 57.26% drugs were prescribed by generic name. Average antimicrobial drug cost per patient was 1805.34 rs.
