Dose Optimization by Pharmacokinetic/Pharmacodynamic of Antibiotics to Improve Clinical Outcome of Carbapenem Resistant Klebsiella Pneumoniae Bloodstream Infections in Critically Ill Patients at Phramongkutklao Hospital

May 7, 2023 updated by: Phramongkutklao College of Medicine and Hospital

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

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
