Antimicrobial resistance is a growing public health concern. Antimicrobial stewardship and multi-disciplinary intervention can prevent inappropriate antimicrobial use and improve patient care. Special populations, especially older adults and patients with mental health disorders, can be particularly in need of such intervention. The purpose of this project was to assess the impact of Pharmacist intervention on appropriateness of antimicrobial prescribing on a patients by market survey. Market survey was conducted among 30 patients about rationale use of antibiotics. It has been observed that antibiotics are prescribed enormously among patients even where they are not required. Out of 30 prescriptions 53% of prescriptions contain irrational antibiotics, which may lead to mild consequences and 33% of prescriptions contain irrational antibiotics, which may lead to severe consequences.
