Evaluation of Antibiotics and Clinical Outcomes along with Various Other Factors in Critically Ill Intensive Care Unit Patients

Abstract

Intensive care units (ICUs) are special hospital wards that provide desired treatment and close monitoring of patients who are critically ill. Drug Utilization Reviews (DUR) is an authorized, structured, ongoing review of patient medication to ensure appropriate and rational medication use to yield positive outcomes. The aim of this study is to evaluate the antibiotics and clinical outcomes in intensive care unit (ICU) patients. This study was cross sectional retrospective (cohort), descriptive and clinical study including patients admitted in ICU of tertiary care hospitals. A total 400 patients (Male 53%) and (Female 47%) were admitted in ICU were analyzed in this study. Majority of patients were from age group between 41 to 60 years i.e., 50.2%. Patients evaluated in this study were suffering from many diseases and comorbidities majorly including respiratory, infectious, nephrology and urology diseases. Antibiotics, majorly penicillins were administered to 185 (46.2%) patients, flouroquinolones 162 (40.5%), cephalosporins 287 (71.8%), carbapenems 102 (25.5%), vancomycin 61 (15.2%) and metronidazole 217 (54.2%) patients. Total 52 (12.5%) patients underwent culture sensitivity test. Significant drug-drug interactions were seen in 64% patients. High mortality rate (72.8%) was seen in this study. It was observed that presence of NI and lack of CST enhanced mortality rate. CST is very important regarding choice of ICU patient’s antibiotic therapy. Current study identified factors affecting the clinical outcomes in terms of morbidity and mortality in the ICU patients. Antibiotics are prescribed in ICU abundantly. Due to presence of drug-drug interactions, nosocomial infections, comorbidities, not having culture sensitivity test (CST) and adverse reactions mortality rate was enhanced. Pharmacist led medication review will help in avoiding all these issues.
