RESUMEN
BACKGROUND: This study aimed to describe the use of carbapenems in a pediatric tertiary center and to assess its compliance with national and local guidelines. METHODS: This retrospective study focused on children who received at least one dose of carbapenems in a tertiary university hospital over a 1-year period (2019). The appropriateness of each prescription was assessed. RESULTS: In total, 96 prescriptions were collected for 75 patients (median age 3 years [interquartile range, IQR: 0-9]). Most prescriptions were empirical (n = 77, 80%) and mainly concerned nosocomial infections (n = 69, 72%). At least one risk factor for extended-spectrum beta-lactamases was found in 48% (n = 46) of cases. The median duration of treatment with carbapenems was 5 days and it was over 7 days in 38% (n = 36) of cases. The use of carbapenems was considered appropriate in 95% (18/19) and 70% (54/77) of cases when therapy was guided by culture results or was empirical, respectively. De-escalation of carbapenem treatment within 72 h occurred in 31% (n = 30) of cases. CONCLUSION: The use of carbapenems can be optimized in the pediatric population, even when the initial prescription for a carbapenem is considered appropriate.

Vancomycin dosing used in neonates results frequently in insufficient concentrations. A vancomycin dose-optimization protocol consisting of an individualization of loading and maintenance doses (administered during continuous infusion) through a previously validated pharmacokinetic model was implemented in our center. This monocenter retrospective study aimed to compare vancomycin average concentration (Cavg) in the therapeutic range (15 to 25 mg/L) and biological and clinical parameters before and after implementation of this protocol. A total of 60 and 59 courses of vancomycin treatment in 45 and 49 patients were analyzed in groups before and after implementation, respectively. Initial vancomycin Cavg were more frequently in the therapeutic range in the group after implementation (74.6% versus 28.3%, P < 0.001), with 1.6-fold higher Cavg (20.3 [17.0-22.2] mg/L versus 12.9 [11.3-17.0] mg/L, P < 0.001). Considering all Cavg during longitudinal therapeutic drug monitoring (TDM), the frequency of therapeutic Cavg was higher in the group after implementation (74.8% [n = 103] versus 31% [n = 116], P < 0.001). The dose optimization protocol was also associated with a reduced time to obtain a negative blood culture (P < 0.001) and fewer antibiotic switches (P = 0.025), without increasing the frequency of nephrotoxicity. Clinical outcomes also appeared to be improved, with less periventricular leukomalacia (P = 0.021), trended toward less respiratory instability (P = 0.15) and a shorter duration of vasoactive drug use (P = 0.18) for neonates receiving personalized doses of vancomycin. This personalized vancomycin dose protocol improves vancomycin exposure in neonates, with good safety, and suggests an improvement in biological and clinical outcomes.

Antibiotic therapy represents one of the most common interventions in pediatric intensive care units (PICUs). This study aims to describe current antimicrobial stewardship programs (ASP) in European PICUs. A cross-sectional survey distributed to European pediatric intensive care physicians through the European Society of Neonatal and Pediatric Intensive Care (ESPNIC) Infection, Inflammation, and Sepsis Section, to members of the Spanish Society of Pediatric Intensive Care, of the Pediatric Reanimation and Emergency Care French Group, and to European physicians known to be involved in antimicrobial stewardship programs. Responses from 60 PICUs across 12 countries were analyzed. Fifty three (88%) stated that ASP was implemented. The main interventions considered as ASP were the pharmacokinetic monitoring of antimicrobials (n = 41, 77%) and the development of facility-specific clinical practice guidelines (n = 40, 75%). The most common team composition of antimicrobial stewardship program included a pediatric infectious disease physician, a pharmacist, and a microbiologist (n = 11, 21%). CONCLUSION: Although ASP practices were reported to be widely implemented across European PICUs, this survey observed a large heterogeneity in terms of activities and modalities of intervention. WHAT IS KNOWN: ⢠Antibiotic therapy represents one of the most common interventions in pediatric intensive care units. ⢠The role and subsequent success of antimicrobial stewardship programs has largely been reported in the adult population but scarcely in the pediatric population. WHAT IS NEW: ⢠Antimicrobial stewardship programs were reported to be widely implemented across European pediatric intensive care units. ⢠We observed a large heterogeneity in terms of activities and modalities of intervention.
