The threat of antimicrobial resistance particularly in the intensive care unit has become a global issue. This study aimed to evaluate the effectiveness of antimicrobial stewardship in limiting the spread of antimicrobial resistance in the hospital’s ICU. The study further determined the deficiencies of the ASP and recommended strategies to remedy the identified deficiencies. A quasi-experimental descriptive quantitative design was used in this study. The study was conducted at the intensive care unit of an academic hospital. A structured questionnaire was used to extract information from patients’ medical records. This evaluation showed that the antimicrobial stewardship program had a sufficient impact on the appropriate use of antimicrobials in the hospital’s ICU. While there were a small (19.05 %) number of patients inappropriately prescribed antimicrobials, a moderate (35.59%) number of patients developed hospital acquired infections during the study period. In addition, the results revealed a lack of the facility’s leadership commitment to antimicrobial stewardship, which is crucial for ensuring the availability of human, financial and information technology resources Through the evaluation of the program the deficiency in the program’s performance can be identified and optimised. For the studied facility, the performance of the program could be improved by gaining the support of the facility leadership. The present study endorses the evaluation of health promotion initiatives to improve patients’ safety and outcome in healthcare institutions. Keywords / Health Studies / D. Litt. et Phil.
