Abstract

Background: A number of antimicrobial drugs are prescribed to the patients in Intensive Care Unit (ICU). 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. Methods: A prospective observational study was carried out for 12 months. Patients of age >18 of both sexes who was admitted in ICU were included in the study while pregnant and lactating women excluded. The prescribing pattern was analyzed by using World Health Organization basic drug indicators.  Results: Among 611 patients, 373 (61.04%) were male and 238 (38.95%) were female. 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. Conclusions: Despite of limitations of present study it gives important conclusion about how antimicrobial drugs are used in GGGH ICU. This information can be used for improvement of current treatment strategies.
