RESUMO
The emergence of multidrug-resistant (MDR) bacteria in children is a growing concern, particularly among septic patients, given the need for first-right dosing. Our aim was to determine the incidence rates and factors associated with MDR-sepsis in the pediatric intensive care unit (PICU), using data from the Spanish ENVIN-HELICS PICU registry between 2013 and 2019. The rate of MDR bacteria among septic children ranged between 5.8 and 16.2% throughout this study period, with a significant increase since 2015 (p = 0.013). MDR-gram-negative bacteria (92%), particularly EBL-Enterobacterales (63.7%), were the most frequent causative microorganisms of MDR-sepsis. During this study period, sixteen MDR-sepsis (32.6%) corresponded to intrahospital infections, and 33 (67.4%) had community-onset sepsis, accounting for 10.5% of the overall community-onset sepsis. Independent risk factors associated with MDR-sepsis were antibiotics 48 h prior to PICU admission (OR 2.38) and PICU onset of sepsis (OR 2.58) in >1 year-old children, and previous malnourishment (OR 4.99) in <1 year-old children. Conclusions: There was an alarming increase in MDR among septic children in Spain, mainly by gram-negative (ESBL-Enterobacterales), mostly coming from the community setting. Malnourished infants and children on antibiotics 48 h prior to PICU are at increased risk and therefore require closer surveillance.
RESUMO
Healthcare-associated infections related to device use (DA-HAIs) are a serious public health problem since they increase mortality, length of hospital stay and healthcare costs. We performed a multicenter, prospective study analyzing critically ill pediatric patients admitted to 26 Spanish pediatric intensive care units (PICUs) over a 3-month period each year from 2014 to 2019. To make comparisons and evaluate the influence of HAI Zero Bundles (care bundles that intend to reduce the DA-HAI rates to zero) on PICU HAI rates, the analysis was divided into two periods: 2014-2016 and 2017-2019 (once most of the units had incorporated all the Zero Bundles). A total of 11,260 pediatric patients were included. There were 390 episodes of HAIs in 317 patients and the overall rate of HAIs was 6.3 per 1000 patient days. The DA-HAI distribution was: 2.46/1000 CVC days for central-line-associated bloodstream infections (CLABSIs), 5.75/1000 MV days for ventilator-associated pneumonia (VAP) and 3.6/1000 UC days for catheter-associated urinary tract infections (CAUTIs). Comparing the two periods, the HAI rate decreased (p = 0.061) as well as HAI episodes (p = 0.011). The results demonstrate that exposure to devices constitutes an extrinsic risk factor for acquiring HAIs. The multivariate analysis highlights previous bacterial colonization by multidrug-resistant (MDR) bacteria as the most important extrinsic risk factor for HAIs (OR 20.4; 95%CI 14.3-29.1). In conclusion, HAI Zero Bundles have been shown to decrease HAI rates, and the focus should be on the prompt removal of devices, especially in children with important intrinsic risk factors.
RESUMO
Antibiotic misuse in pediatric intensive care units (PICUs) can lead to increased antimicrobial resistance, antibiotic-triggered side effects, hospital costs, and mortality. We performed a multicenter, prospective study, analyzing critically ill pediatric patients (≥1 month to ≤18 years) admitted to 26 Spanish PICUs over a 3-month period each year (1 April−30 June) from 2014−2019. To make comparisons and evaluate the influence of AMS programs on antibiotic use in PICUs, the analysis was divided into two periods: 2014−2016 and 2017−2019 (once 84% of the units had incorporated an AMS program). A total of 11,260 pediatric patients were included. Total antibiotic prescriptions numbered 15,448 and, overall, 8354 patients (74.2%) received at least one antibiotic. Comparing the two periods, an increase was detected in the number of days without antibiotics in patients who received them divided by the number of days in PICUs, for community-acquired infections (p < 0.001) and healthcare-associated infections (HAIs) acquired in PICUs (p < 0.001). Antibiotics were empirical in 7720 infections (85.6%), with an increase in appropriate antibiotic indications during the second period (p < 0.001). The main indication for antibiotic adjustment was de-escalation, increasing in the second period (p = 0.045). Despite the high rate of antibiotic use in PICUs, our results showed a significant increase in appropriate antibiotic use and adjustment following the implementation of AMS programs.
RESUMO
BACKGROUND AND OBJECTIVES: Pertussis remains an important cause of morbimortality despite current vaccination strategies. This study was designed to describe the results and characteristics of close contacts of pertussis cases diagnosed in children less than 16 years in a tertiary hospital in Barcelona. PATIENTS AND METHODS: Cross-sectional study. Data were collected from chart review of contacts of paediatric cases of pertussis in Vall d'Hebron University Hospital from 2005 to 2009. Only patients with microbiological study done were included. The odds ratio (OR) and 95% confidence interval (95% CI) were calculated as association measure. RESULTS: Ninety-one index cases and 404 contacts were studied. The prevalence of positive cases among contacts was 33.2%. Contacts of index cases younger than 6 months had a higher risk of being positive for pertussis than contacts of older children (OR: 3.38; 95% CI: 1.88-6.10). Primary cases were identified as 16.7% of the contacts studied, who were the source of infection for 67.7% of index cases younger than 6 months and for 26.9% of older index cases. CONCLUSIONS: Contact tracing of paediatric pertussis cases is a necessary clinical activity. It is more likely to find primary cases in the contact investigation of children less than 6 months. Preventive strategies should be targeted primarily to frequent contacts of this age group.

Fundamento y objetivo: La tos ferina sigue siendo una importante causa de morbimortalidad a pesar de las actuales estrategias vacunales. Se diseñó este estudio para describir los resultados y las características de los contactos estrechos de casos de tos ferina diagnosticados en menores de 16 años en un hospital de tercer nivel de Barcelona. Pacientes y método: Estudio transversal. Los datos se recogieron a partir de las historias clínicas de los contactos de los casos pediátricos diagnosticados de tos ferina en el Hospital Universitario Vall dHebron de 2005 a 2009. Se incluyeron solo pacientes con estudio microbiológico realizado. Se calculó la odds ratio (OR) con su intervalo de confianza del 95% (IC 95%) como medida de asociación. Resultados: Fueron estudiados 91 casos índice y 404 contactos. La prevalencia de casos positivos entre los contactos fue del 33,2%. Los contactos de los casos índice menores de 6 meses presentaron más riesgo de ser positivos que los contactos de los niños mayores (OR 3,38; IC 95% 1,88-6,10). Se identificaron como casos primarios el 16,7% de los contactos estudiados. Estos representaron la fuente de contagio para el 67,7% de los casos índice menores de 6 meses y para el 26,9% de los niños mayores. Conclusiones: El estudio de contactos de casos pediátricos de tos ferina es una actividad clínica necesaria. Es más probable hallar casos primarios en el estudio de contactos de niños menores de 6 meses. Las estrategias preventivas deben ir dirigidas fundamentalmente a los contactos frecuentes de este grupo (AU)
