Objectives: An objective categorization of respiratory infections based on outcomes is an unmet clinical need. Ventilator-associated pneumonia and tracheobronchitis remain used in clinical practice, whereas ventilator-associated events (VAE) are limited to surveillance purposes., Research Methodology/design: This was a secondary analysis from a multicentre observational prospective cohort study. VAE were defined as a sustained increase in minimum Oxygen inspired fraction (FiO2) and/or Positive end-expiratory pressures (PEEP) of ≥ 0.2/2 cm H 2 O respectively, or an increase of 0.15 FiO 2  + 1 cm H20 positive end-expiratory pressures for ≥ 1 calendar-day., Setting: 15 Paediatric Intensive Care Units., Main Outcome Measures: Mechanical ventilation duration, intensive care and hospital length of stay; (LOS) and mortality., Results: A cohort of 391 ventilated children with an age (median, [Interquartile Ranges]) of 1 year[0.2-5.3] and 7 days[5-10] of mechanical ventilation were included. Intensive care and hospital stays were 11 [7-19] and 21 [14-39] days, respectively. Mortality was 5.9 %. Fifty-eight ventilator-associated respiratory infections were documented among 57 patients: Seventeen (29.3 %) qualified as ventilator-associated pneumonia (VAP) and 41 (70.7 %) as ventilator-associated tracheobronchitis (VAT). Eight pneumonias and 16 tracheobronchitis (47 % vs 39 %,P = 0.571) required positive end-expiratory pressure or oxygen increases consistent with ventilator-associated criteria. Pneumonias did not significantly impact on outcomes when compared to tracheobronchitis. In contrast, infections (pneumonia or tracheobronchitis) following VAEs criteria were associated with > 6, 8 and 15 extra-days of ventilation (16 vs 9.5, P = 0.001), intensive care stay (23.5 vs 15; P = 0.004) and hospital stay (39 vs 24; P = 0.015), respectively., Conclusion: When assessing ventilated children with respiratory infections, VAE apparently is associated with higher ventilator-dependency and LOS compared with pneumonia or tracheobronchitis., Implications for Practice: Incorporating the modification of ventilatory settings for further categorization of the respiratory infections may facilitate therapeutic management among ventilated patients., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

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.

Introduction: The purpose of this study is to describe the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) disease characteristics and management in children admitted to the pediatric intensive care units (PICU)., Methods: The present study was based on a national multicentric prospective registry including PICU patients with SARS-CoV2 infection or symptoms of multisystem inflammatory syndrome in children (MIS-C)., Results: A total of 298 patients were admitted to 41 different Spanish PICUs. A total of 76% of them were previously healthy. The most frequent manifestation was MIS-C (69.8%). On admission, 59.4% of patients did not have respiratory distress, and only 17.4% needed conventional mechanical ventilation (MV). The need for MV was associated with age (incidence rate ratios [IRR] 1.21, p < .012), pediatric sequential organ failure assessment score (p-SOFA) Score (IRR 1.12, p = .001), and need for transfusion (IRR 4.5, p < .004) in MIS-C patients, and with vasoactive drug use (IRR 2.73, p = .022) and the diagnosis of acute respiratory distress syndrome (IRR 2.83, p = .018) in patients admitted for other reasons. During the first day of admission, 56% of patients met shock criteria and 50.7% needed vasoactive drugs. In MIS-C patients, their use was associated with higher p-SOFA score (IRR 1.06, p < .001) and with the diagnosis of shock (IRR 5.78, p < .001). In patients without MIS-C, it was associated with higher p-SOFA score (IRR 1.05, p = .022). The mortality rate was 3%, being lower in MIS-C patients compared to patients admitted for other reasons (0.5% vs. 9.4%, p < .001). It was also lower in previously healthy patients compared to patients with previous comorbidities (0.9% vs. 9.7%, p < .001)., Conclusions: Severe SARS-CoV2 infection is uncommon in the pediatric population. In our series, respiratory distress was rare, being MIS-C the most frequent cause of PICU admission related to SARS-CoV2. In most cases, the course of the disease was mild except in children with previous diseases., (© 2023 The Authors. Pediatric Pulmonology published by Wiley Periodicals LLC.)

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.

Introduction: Drowning is one of the most frequent accidents in children. We aimed to describe demographic and epidemiological characteristics of drowned children who required admission to a pediatric intensive care unit (PICU) to identify risk factors to guide possible preventive measures to avoid severe drowning., Methods: We conducted an observational study for 29 years (retrospective between 1991 and 2004; prospective between 2005 and 2019) that included all children (0-15 years old) requiring PICU admission after drowning. Data regarding patient characteristics, accident circumstances, and neurological outcomes at PICU discharge were analyzed., Results: A total of 160 patients were included, with no significant decrease over the study period. There was a predominance of males (75%), young age (60%; 1-5 years), summer months (91.1%; May-September), tourists (14.12 [95% confidence interval, 9.2-21.7] times higher risk of drowning than residents), swimming pool accidents (88.8%), and inadequate supervision (77.9%). The mortality was 18.7%, and 7.5% of admitted children had severe neurological sequelae. The initial resuscitation maneuvers by accident witnesses were incorrect in nearly half of the patients in whom these could be analyzed., Conclusions: Emphasis should be placed on implementing preventive measures, focused on the described risk groups, and insisting on adequate supervision, swimming training programs, and training of the general population in safe rescue and cardiopulmonary resuscitation., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

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.

Objective: The aim of this study was to evaluate the prognostic factors of patients admitted to a pediatric intensive care unit (PICU) after drowning., Methods: Retrospective observational study from January 1992 to December 2004 and prospective study from January 2005 to December 2015 were conducted in a tertiary children's hospital PICU. The data analyzed refer to the patient, event, type of resuscitation performed, and clinical situation after resuscitation and at arrival to the PICU; results of additional tests; and clinical evolution and neurological status at discharge from the PICU (categorized as death, severe encephalopathy, or normal). The considered potential prognostic factors were whether drowning was witnessed, the type of initial resuscitation, Glasgow Coma Scale score at admission, pupil status and reactivity, and pH., Results: One hundred thirty-one patients were registered. Mortality was 16.7%, and 8.3% had significant neurological sequelae. The clearest factor associated with poor outcome was the type of initial resuscitation performed. All patients who did not require cardiopulmonary resuscitation (CPR), or only basic CPR, had good outcomes; 96.3% of those who required advanced CPR with epinephrine administration had poor outcomes. Patients who needed advanced resuscitation with administration of epinephrine had lower temperature, Glasgow Coma Scale score, pH, and bicarbonate at admission and higher level of glucose. In this group, there was also a higher incidence of seizures, acute respiratory distress syndrome, hemodynamic compromise, and acute renal failure., Conclusions: The need for advanced CPR with epinephrine administration on the scene predicts poor neurological outcome (severe encephalopathy or death) in drowned children., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2018 Wolters Kluwer Health, Inc.

A new paediatric multisystem inflammatory syndrome, linked to SARS-CoV-2, has been described. The clinical picture is variable and is associated with an active or recent infection due to SARS-CoV-2. A review of the existing literature by a multidisciplinary group of paediatric specialists is presented in this document. Later, they make recommendations on the stabilisation, diagnosis, and treatment of this syndrome., (Copyright © 2020 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U.

Background: Multisystem inflammatory syndrome temporally associated with COVID-19 (MIS-C) has been described as a novel and often severe presentation of SARS-CoV-2 infection in children. We aimed to describe the characteristics of children admitted to Pediatric Intensive Care Units (PICUs) presenting with MIS-C in comparison with those admitted with SARS-CoV-2 infection with other features such as COVID-19 pneumonia., Methods: A multicentric prospective national registry including 47 PICUs was carried out. Data from children admitted with confirmed SARS-CoV-2 infection or fulfilling MIS-C criteria (with or without SARS-CoV-2 PCR confirmation) were collected. Clinical, laboratory and therapeutic features between MIS-C and non-MIS-C patients were compared., Results: Seventy-four children were recruited. Sixty-one percent met MIS-C definition. MIS-C patients were older than non-MIS-C patients (p = 0.002): 9.4 years (IQR 5.5-11.8) vs 3.4 years (IQR 0.4-9.4). A higher proportion of them had no previous medical history of interest (88.2% vs 51.7%, p = 0.005). Non-MIS-C patients presented more frequently with respiratory distress (60.7% vs 13.3%, p < 0.001). MIS-C patients showed higher prevalence of fever (95.6% vs 64.3%, p < 0.001), diarrhea (66.7% vs 11.5%, p < 0.001), vomits (71.1% vs 23.1%, p = 0.001), fatigue (65.9% vs 36%, p = 0.016), shock (84.4% vs 13.8%, p < 0.001) and cardiac dysfunction (53.3% vs 10.3%, p = 0.001). MIS-C group had a lower lymphocyte count (p < 0.001) and LDH (p = 0.001) but higher neutrophil count (p = 0.045), neutrophil/lymphocyte ratio (p < 0.001), C-reactive protein (p < 0.001) and procalcitonin (p < 0.001). Patients in the MIS-C group were less likely to receive invasive ventilation (13.3% vs 41.4%, p = 0.005) but were more often treated with vasoactive drugs (66.7% vs 24.1%, p < 0.001), corticosteroids (80% vs 44.8%, p = 0.003) and immunoglobulins (51.1% vs 6.9%, p < 0.001). Most patients were discharged from PICU by the end of data collection with a median length of stay of 5 days (IQR 2.5-8 days) in the MIS-C group. Three patients died, none of them belonged to the MIS-C group., Conclusions: MIS-C seems to be the most frequent presentation among critically ill children with SARS-CoV-2 infection. MIS-C patients are older and usually healthy. They show a higher prevalence of gastrointestinal symptoms and shock and are more likely to receive vasoactive drugs and immunomodulators and less likely to need mechanical ventilation than non-MIS-C patients.

On 31 December 2019, the Wuhan Municipal Committee of Health and Healthcare (Hubei Province, China) reported that there were 27 cases of pneumonia of unknown origin with symptoms starting on the 8 December. There were 7 serious cases with common exposure in market with shellfish, fish, and live animals, in the city of Wuhan. On 7 January 2020, the Chinese authorities identified that the agent causing the outbreak was a new type of virus of the Coronaviridae family, temporarily called «new coronavirus», 2019-nCoV. On January 30th, 2020, the World Health Organisation (WHO) declared the outbreak an International Emergency. On 11 February 2020 the WHO assigned it the name of SARS-CoV2 and COVID-19 (SARS-CoV2 and COVID-19). The Ministry of Health summoned the Specialties Societies to prepare a clinical protocol for the management of COVID-19. The Spanish Paediatric Association appointed a Working Group of the Societies of Paediatric Infectious Diseases and Paediatric Intensive Care to prepare the present recommendations with the evidence available at the time of preparing them., (Copyright © 2020 Asociación Española de Pediatría.

Introduction: Nosocomial infections (NI) are a major healthcare problem. National surveillance systems enable data to be compared and to implement new measures to improve our practice., Methods: A multicentre, prospective, descriptive and observational study was conducted using the data from surveillance system for nosocomial infections created in 2007 for Spanish pediatric intensive care units. Data were collected for one month, between 01 and 31 March, for every study year (2008-2012). The objective was to report 5-years of NI surveillance data, as well as trends in infections by multidrug resistant organisms in Spanish pediatric intensive care units., Results: A total of 3667 patients were admitted to the units during the study period. There were 90 (2.45%) patients with nosocomial infections. The mean rates during the 5 years study were: central line-associated bloodstream infection, 3.8/1000 central venous catheter-days, Ventilator-associated pneumonia 7.5/1000 endotracheal tube-days, and catheter-associated urinary tract infections 4.1/1000 urinary catheter-days. The comparison between the 2008 and 2009 rates for nosocomial infections did not show statistically significant differences. All rates homogeneously decreased from 2009 to 2012: central line-associated bloodstream infection 5.83 (95% CI 2.67-11.07) to 0.49 (95% CI 0.0125-2.76), P=0.0029; ventilator-associated pneumonia 10.44 (95% CI 5.21-18.67) to 4.04 (95% CI 1.48-8.80), P=0.0525; and Catheter-associated urinary tract infections 7.10 (95% CI 3.067-13.999) to 2.56 (95% CI 0.697-6.553), P=0.0817; respectively. The microorganism analysis: 63 of the 99 isolated bacteria (63.6%) were Gram-negative bacteria (36.5% were resistant), 19 (19.2%) Gram-positive bacteria, and 17 (17.2%) were Candida spp. infections., Conclusions: The local surveillance systems provide information for dealing with nosocomial infections rates., (Copyright © 2015 Elsevier España, S.L.U. y Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.
