Purpose:
To describe meropenem empirical use, susceptibility trend, and associated factors for acquired nonsusceptibility in P. aeruginosa in the intensive care unit.
Patients And Methods:
This study was conducted in the intensive and high care unit of a tertiary care hospital in Indonesia to evaluate empirical meropenem bolus administration protocol. All patients admitted during the 3 year study period from January 2018 through January 2021 with culture-confirmed P. aeruginosa infection were included in the study. Primary data were collected from hospital database electronic medical record and series of local biannual report of microorganism susceptibility pattern.
Results:
The data suggested that there was increasing trend in meropenem nonsusceptibility and multidrug-resistance rates. A total of 135 patients with various primary diagnoses and comorbidities were studied. P. aeruginosa isolates were mostly (73.4%) obtained from sputum specimen. Empirical meropenem therapy was administrated in 24.4% of patients with standard- and high-dose as indicated. Nonsusceptibility was acquired in 37% patients who mostly received empirical therapy. Multivariable analysis revealed protocol being evaluated as a statistically significant risk factor for nonsusceptibility in P. aeruginosa (PR = 30.65; p <0.001).
Conclusion:
Empirical meropenem administration protocol in this study was an independent determinant of nonsusceptibility acquisition in P. aeruginosa. These findings proved that empirical therapeutic strategy modification is indispensable and routine evaluation practice should be promulgated.
Insights
The study found that the empirical meropenem administration protocol increased nonsusceptibility in Pseudomonas aeruginosa. Modifying empirical therapeutic strategies is crucial for combating antimicrobial resistance.
Area of Science:
- Infectious Diseases
- Clinical Pharmacy
- Microbiology
Background:
- Antimicrobial resistance is a growing global health concern.
- Pseudomonas aeruginosa is a common cause of hospital-acquired infections, particularly in intensive care units.
- Meropenem is a critical antibiotic for treating P. aeruginosa infections.
Purpose of the Study:
- To investigate the empirical use of meropenem.
- To analyze the susceptibility trends of P. aeruginosa to meropenem.
- To identify factors associated with acquired nonsusceptibility in P. aeruginosa within an intensive care unit setting.
Main Methods:
- A retrospective study was conducted in an Indonesian tertiary care hospital's intensive and high care unit.
- Data from January 2018 to January 2021 included patients with culture-confirmed P. aeruginosa infections.
- Hospital electronic medical records and microorganism susceptibility reports were analyzed.
Main Results:
- An increasing trend in meropenem nonsusceptibility and multidrug-resistance rates was observed.
- Nonsusceptibility to meropenem was acquired in 37% of patients, with most receiving empirical therapy.
- The evaluated empirical meropenem administration protocol was a significant risk factor for P. aeruginosa nonsusceptibility (PR = 30.65; p <0.001).
Conclusions:
- The empirical meropenem administration protocol independently contributed to the acquisition of nonsusceptibility in P. aeruginosa.
- Modifications to empirical therapeutic strategies are essential.
- Routine evaluation of antimicrobial use practices should be implemented to mitigate resistance.
