Dose Optimization by PK/PD of Antibiotics to Improve Clinical Outcome of CRKP Bloodstream Infections in Critically Ill Patients and in Vitro Study of Monotherapy, Combination Therapy and Molecular Biology of Drug Resistance at Phramongkutklao Hospital: Prospective, Historical Controlled Study

PMK-0008

The patients who infected with Carbapenem resistant Klebsiella pneumoniae were high mortality rate. Appropriate antibiotics therapy adjusted by Pharmacokinetic/Pharmacodynamic plays an important role in determining outcomes in Critically ill patients. Consequently, standard antibiotics dose may not be adequate to achieve pharmacokinetic/pharmacodynamic target in Critically ill patients. The purpose of this study is to compare the clinical outcomes between the critically ill patients who received antibiotics dose adjusted by pharmacokinetic/pharmacodynamic using Monte Carlo simulation and historical critically ill patients who received antibiotics from standard practice.
