Registration Number

Università Vita-Salute San Raffaele
Brief Summary

This study arises from the need to optimize antibacterial drug usage to face increasing drug resistance among gram-negative pathogens in intensive care units. Gram-negative organisms are responsible for 70% of drug-resistant infections acquired in the intensive care unit. Meropenem is a β-lactam, carbapenem, antibacterial agent usually administered by intermittent infusion. As β-lactam efficacy is determined by the time in which the drug concentration exceeds the minimum inhibiting concentration of the target pathogen, intermittent infusion of this short half-lived drug can lead to precipitous drops in serum drug levels, an occurrence linked to emergence of resistant pathogens. The investigators hypothesize a beneficial effect of a continuous meropenem infusion on mortality and emergence of drug resistant pathogens. All patients enrolled will receive 1 g of meropenem bolus. After that, subjects will be randomized to receive a continuous infusion of study drug 3g/day or a bolus administration of the same amount of drugs. The investigators expect a reduction of mortality and emergence of extensive or pan drug resistant pathogens from 52 to 40% in the continuous infusion group.

Inclusion Criteria

Will be enrolled patients who:

  • Are able to express informed consent or the latter can be given by his/her next of kin or as requested by Ethical Committee.

Continuous infusionMeropenemPatient randomized to continuous infusion group, will receive a continuous infusion of meropenem according to their renal function (creatinine clearance -ClCr- estimated by Cockcroft-Gault formula and study day 1. for ClCr \> 50 ml/min: 3 g / day, prepared as follows: 10 mg/ml of meropenem in NaCl 0.9% at 12,5 ml/h. 2. for ClCr \< 50 ml/min: 2 g / day, prepared as follows: 10 mg/ml of meropenem in NaCl 0.9% at 8,3 ml/h. This solution will be replaced every time its duration exceeds the stability in use stated by the producer

Primary Outcome Measures
NameTimeMethod
Death or Emergence of new resistant bacteriaday 28

composite outcome:

1. death from any cause at day 28

2. emergence of new XDR (extended drug resistant) or PDR (pan drug resistant) bacteria at day 28

Secondary Outcome Measures
NameTimeMethod
Death from any causeday 90

Death from any cause

Cumulative SOFA-free pointup to day 28

SOFA score will be evaluated every day up to day 28. SOFA-free daily score is 24 (maximum SOFA) minus actual SOFA. Cumulative SOFA-free is the sum of SOFA-free daily from randomization to date 28. Patients dead before day 28 can't ameliorate their SOFA-free score. This way, the higher the cumulative SOFA-free, the higher is the amelioration of the patient and his probability of survival.

Antibiotic-free daysup to day 28 or death

Proportion of days from randomization to day 28 or death in which subject didn't receive any antibiotics (excluding anti-fungal anti-viral drugs)

ICU - free daysday 28 or death

Number of days from randomization to day 28 (or death) in which the subject is outside the ICU. For any discharge lasting less than 48h, no ICU-free day will be computed. Re-admission lasting less than 24 hours will not reduce ICU-free days. Patients that will not survive outside ICU for at least 48 hours, will have a ICU-free day of zero
