Brief summary

The aim of this study is to investigate if an initial short double dose of beta-lactam antibiotics will reduce mortality in critically ill patients with sepsis.

Detailed description

Objective To determine if using higher dosages of beta-lactam antibiotics in the initial phase of sepsis improves clinical outcome of critically ill patients. Main trial endpoints The main trial endpoint is all cause 28-day mortality. Secondary trial endpoints Secondary trial endpoints include: Hospital length of stay, ICU length of stay, microbiological eradication, time to shock reversal, clinical cure, Δ Lactate, Δ PCT, Δ SOFA, 90- day mortality, 365-day mortality, pharmacodynamic target, post study calculation of the costs in both study, groups, EQ5D questionnaire 3 and 12 months after Admission, iMTA productivity questionnaire 3 and 12 months after admission, iMTA medical consumption questionnaire 3 and 12 months after admission and the number of adverse events. Trial design This is an open label, randomized controlled trial. Trial population The trial population will consist of adult patients admitted to the intensive care department with sepsis who will be treated according to protocol with beta-lactam antibiotics. Interventions During the trial participants in the intervention group will receive a double dose of antibiotics for the first 48 hours in comparison to the standard dose in the control group.

Inclusion criteria

* ≥18 years of age * Receiving intravenous antibiotic therapy of the target drugs (including continuous infusion of beta-lactam antibiotics) * Primary infection * Admitted to the ICU * Meeting the Sepsis-3 criteria for septic shock: sepsis in addition to shock requiring the start of vasopressors to maintain a mean arterial pressure 65 mmHg or greater, and a serum lac tate level greater than 2.0 mmol/L following adequate fluid resuscitation.

Exclusion criteria

* Patient or legal representative not available to give informed consent within 72 hours after admittance * Pregnancy * Admittance for burn wounds * Patients receiving target antibiotics only as prophylaxis within the context of Selective Diges tive tract Decontamination (SDD) * Enrolment in another interventional trial * Patient received the study antibiotic for more than 24 hours before inclusion * Patient receiving extracorporeal membrane oxygenation (ECMO) * Patient is already treated with a double dose of antibiotics based on suspected infection

Design outcomes

Primary

MeasureTime frame
28-day mortalityFrom enrollment to 28 days

Secondary

MeasureTime frameDescription
365-day mortalityFrom enrollment to the 365 days
ICU lengt of stayFrom enrollment to the end of the study period at 12 months
Hospital lengt of stayFrom enrollment to the end of the study period at 12 months
Time to shock reversalFrom enrollment to the end of the study period at 12 monthsFrom enrollment to the use of \<0.1 gamma of vasopressors for 4 consecutive hours.
Microbiological eradicationFrom enrollment to hospital dischargeEradication of the causative organism from the primary source up to 30 days after therapy when confirmed by at least one repeated culture. In cases where there were no repeat cultures and the patient had resolution of the infection, microbial eradication will be presumed.
Clinical cureFrom enrollment to 14 daysCompletion of β-lactam antibiotic by day 14 without recommencement of antibiotics within 48hrs of cessation for same infective episode (investigator assessment of clinical response)
90-day mortalityFrom enrollment to 90 days
Delta SOFAFrom enrollment to day 3SOFA at day 3 - SOFA at admission
Delta LactateFrom enrollment to day 3Lactate at day 3 - lactate upon inclusion
Quality of life3 and 12 months after inclusionEQ-5D-5L, a quetionnaire scoring 1 to 5 points on 5 domains. A higher score means a worse outcome.
Medical consumption3 and 12 months after inclusioniMTA Medical Consumption questionnaire
Productivity3 and 12 months after inclusioniMTA Productivity questionnaire
Adverse events and toxicityFrom enrollment until the end of the study period at 12 months
Plasma concentrations of the beta-lactam antibioticsFrom enrollment to day 3Through concentrations take once a day for 3 consectutive days after enrollment. Target attianment is defined as 100%fT\>4xMIC
