Abstract
Background: Antibiotics are commonly administered therapies in ICU. There has been a concern over antibiotic misuse recently. ICU is both a victim and a contributor to the ongoing antibiotic misuse problem and a cause of emerging resistance among the pathogens commonly acquired in intensive care units. Because of high mortality associated with sepsis, it is a great challenge for intensive care physicians to select appropriate antibiotic sometimes without any culture and sensitivity. Similarly the time to deescalate also remains a tough call. Selection of appropriate antibiotics empirically has always been a topic of debate among Intensive Care and Infectious Disease practitioners. Objective: The aim of our pilot study was not only to assess the appropriateness of use of antibiotics in our ICU but to help us guide to design a bigger study and structure a stewardship program for ICU; also to assess the differences among prescription of ICU and Infectious Disease Consultants. Method: A prospective observational study in King Saud Medical City ICU following antibiotics started and stopped from 6th November 2014 to 23rd November 2014. Study included 23 adult patients admitted with different etiologies. All 23 patients’ records were shared with two alien referees (one was infectious diseases and other was ICU consultant) from other hospital. Prescribers were blinded to the fact that data was being collected for auditing and the referees were blinded to prescribers and to each other’s. Results: Total 46 antibiotics were used. 40 among them were started on empirically, 6 were culture based. 31 antibiotics were stopped by ICU. 28 among these 31 antibiotics were empirical. Most of included patients responded to combination or monotherapy. Piperacillin-Tazobactam was the most commonly prescribed antibiotic. No major difference was noted among the choice of intensive care or infectious disease consultant. Conclusion: Empirical antibiotics are vital for patients admitted in ICU. We need to follow hospital's anti-biogram and stewardship programs with prompt de-escalation wherever appropriate.

Summary
Selection of antibiotics in the era of high resistance and lack of new antimicrobial development in intensive care settings is crucial [1,2]. Appropriate administration of antibiotics is major determinant for the outcomes in case of severe bacterial infections in intensive care (ICU) settings [3]. To avoid unnecessary antibiotic administration and increase therapeutic effectiveness usually locally accepted or national society based guideline or protocols are followed. ICU is both a victim and a contributor to the ongoing antibiotic misuse problem and a cause of emerging resistance among the pathogens commonly acquired in intensive care units. Because of high mortality associated with sepsis, it is a great challenge for intensive care physicians to select appropriate antibiotic sometimes without any culture and sensitivity. Selection of appropriate antibiotics empirically has always been a topic of debate among Intensive Care and Infectious Disease practitioners
