Evaluating antibiotic effectiveness in patients with infections

Routinely Collected Clinical Data and Evaluation of Antimicrobial Target Attainment and the Potential Role of Therapeutic Drug Monitoring in UK Infection Management

Imperial College London · NCT06427317

This study is testing how well beta-lactam antibiotics work for patients with infections by checking if they get the right amount of the medicine in their system to help them recover.

What this trial studies

This observational study aims to determine how many patients at Imperial College Healthcare NHS Trust receiving beta-lactam antibiotics achieve the necessary drug concentration targets for effective treatment. By analyzing routinely collected clinical data and drug concentration samples, the study seeks to understand the relationship between clinical variables and treatment outcomes. It also aims to identify gaps in current dosing practices and prioritize areas for further research on drug optimization. Participants will be monitored during their infection management, providing valuable insights into antimicrobial effectiveness.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 who are being treated for infections and have received beta-lactam antibiotics within the last 48 hours.

Not a fit: Patients under 18, those with severe blood disorders, or those receiving palliative care may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved antibiotic dosing strategies, enhancing treatment outcomes and reducing the risk of antimicrobial resistance.

How similar studies have performed: While the approach of optimizing antibiotic dosing is well-recognized, this specific observational study may provide novel insights into real-world dosing effectiveness.
