Completed
Conditions
Antibiotic Toxicity
Sepsis
Septic Shock
Critical Illness
Interventions
Other: dosage of concentration of piperacillin and cefepim
Registration Number
NCT04530045
Lead Sponsor
Central Hospital, Nancy, France
Brief Summary

Although alternative dosing strategies can improve antimicrobial exposure in critically ill patients, the high PK variability in this population means that some may still receive sub-optimal antibiotic exposure leading to unfavourable clinical outcomes.

Therapeutic drug management (TDM) guided dosing is the only safe and effective way to ensure that all critically ill patients achieve therapeutic antimicrobial exposures and to minimise the likelihood of toxicity.

For experts, TDM should be a standard of care, in particular for β-lactams. Nevertheless, because of the assay method for β-lactams and the need for bioanalytical experts, delays in obtaining results frequently occurred. These barriers, combined with difficulties in the interpretation of TDM results, need to be addressed in order to increase its routine utilization. Consequently, study aiming at identify which subgroup of patients or infection are more likely to benefit from TDM are urgently warranted This prospective observational study aimed at evaluating target attainment of piperacillin/tazobactam (PIP/TAZ) and cefepim (CEF) with the use of a Therapeutic Drug Monitoring (TDM) in critically patients during the routine care

Primary Outcome Measures
NameTimeMethod
to determine the percentage of patients who met the PK/PD targets at 24 hoursDay 1

PK/PD target was defined as follows:

Concentration of piperacillin or cefepim between a lower and a upper limit:

* The lower limit was defined as estimated free concentration above 4 times the epidemiological cut-off value of suspected bacteria

* The upper limit was based on known limit of neurotoxicity, namely 35 and 160 mg/L for cefepim and piperacillin, respectively

Consequently :

* for piperacillin : the PK/PD target is considered to be reach if the free concentration of PIPERACILLIN/TAZOBACTAM is between 32 and 160 mg/l

* for cefepim : the PK/PD target is considered to be reach if the free concentration of CEFEPIM is between 4 and 35 mg/l

Secondary Outcome Measures
NameTimeMethod
to determine the percentage of patients who met the PK/PD targets "exposure" at 24 hoursDay 1

PK/PD target "exposure" take into account only the the lower limit was defined as estimated free concentration above 4 times the epidemiological cut-off value of suspected bacteria

Consequently :

* for piperacillin : the PK/PD target is considered to be reach if the free concentration of PIPERACILLIN/TAZOBACTAM is above 32 mg/l

* for cefepim : the PK/PD target is considered to be reach if the free concentration of CEFEPIM is above 4 mg/l

factors associated with target attainment at day 1Statistical analysis after 2 years of inclusion

effect of presence of septic shock on antibiotic concentration

factors associated with dose changingStatistical analysis after 2 years of inclusion

effect of renal clearance on number of dose changing after analyse of antibiotic concentration
