1Programa Asistencial de Patología Infecciosa, Corporació Sanitària Parc Taulí, 08208 Sabadell, Barcelona.
Summary
Piperacillin remains a key antibiotic for treating hospital-acquired infections, particularly in neutropenic patients and pneumonia. It shows continued effectiveness against Pseudomonas aeruginosa.
Area of Science:
- Infectious Diseases
- Pharmacology
- Hospital Pharmacy
Background:
- Piperacillin is a widely used beta-lactam antibiotic.
- Its efficacy and indications in general hospital settings require ongoing evaluation.
- Understanding antibiotic usage patterns is crucial for antimicrobial stewardship.
Purpose of the Study:
- To retrospectively analyze the utilization of piperacillin in a general hospital.
- To identify the primary therapeutic indications for piperacillin use.
- To assess treatment outcomes and microbiological data associated with piperacillin therapy.
Main Methods:
- Retrospective data collection from 338 patients treated with piperacillin between January 1996 and December 1997.
- Analysis of 385 infectious episodes, including patient demographics, diagnoses, and treatment regimens.
- Microbiological data including culture sources and identified pathogens were reviewed.
Main Results:
- Neutropenic infections (39.2%) and nosocomial infections were primary indications.
- Piperacillin was frequently combined with aminoglycosides (86.2%).
- Gram-negative bacilli, including Pseudomonas aeruginosa and Escherichia coli, were common pathogens.
Conclusions:
- Piperacillin is indicated for neutropenic infections and nosocomial pneumonia.
- The antibiotic demonstrates sustained activity against Pseudomonas aeruginosa.
- Piperacillin remains a valuable therapeutic option in general hospital settings.
