IgG antispike persistence and immunophenotype in children infected by SARS-CoV-2.

AIM: The immune status of children recovering from SARS-CoV-2 infection is not completely understood. We describe IgG antispike persistence in children infected during the first two pandemic waves. In addition, we compared with healthy controls their leukocyte populations and CD64 expression. METHODS: Cross-sectional study. Carried out from October 2021 to February 2022 in nonreinfected and nonvaccinated children with SARS-CoV-2 in 2020. The presence of antispike IgG was studied using chemiluminescent immunoassay. Leukocyte populations were analysed using flow cytometry and marked for CD45, CD4, CD8 and CD64. Statistical minor than 0.05 was considered significant. RESULTS: One hundred and eighty-three control and 77 patients were included. IgG antispike determinations were performed after a median of 501 days (262-464); 52 of 77 children were positive. Cases showed significantly higher percentages of monocytes, lymphocytes, CD8+ and CD4+ . In addition, CD64 expression was higher in monocytes and neutrophils. The presence of IgG antispike was accompanied by a higher percentage of CD64+ neutrophils. CONCLUSION: In our series, the SARS-CoV-2 IgG antispike protein was usually positive beyond 1 year after infection. Furthermore, leukocyte populations from cases differ from controls, with higher CD64 expression on neutrophils and monocytes. Prospective clinical observations are required to confirm the implications of these findings.

Mucocutaneous manifestations in children hospitalized with COVID-19.

BACKGROUND: Cutaneous manifestations in hospitalized children with SARS-CoV-2 have not been studied systematically. OBJECTIVE: To describe the mucocutaneous involvement in pediatric patients with COVID-19 admitted to a pediatric institution in Madrid (Spain), located in a zone reporting among the highest prevalence of COVID-19 in Europe. METHODS: A descriptive, analytical study was conducted on a series of 50 children hospitalized with COVID-19 between March 1, 2020, and November 30, 2020. RESULTS: Twenty-one patients presented with mucocutaneous symptoms: 18 patients with macular and/or papular exanthem, 17 with conjunctival hyperemia, and 9 with red cracked lips or strawberry tongue. Eighteen patients fulfilled criteria for multisystem inflammatory syndrome in children. Patients with mucocutaneous involvement tended to be older and presented to the emergency department with poor general status and extreme tachycardia, higher C-reactive protein and D-dimer levels, and lower lymphocyte counts than patients without skin signs. Mucocutaneous manifestations pose a higher risk of admission to the pediatric intensive care unit (odds ratio, 10.24; 95% confidence interval, 2.23-46.88; P = .003). CONCLUSIONS: Children hospitalized with COVID-19 frequently had mucocutaneous involvement, with most symptoms fulfilling criteria for multisystem inflammatory syndrome in children. Patients with an exanthem or conjunctival hyperemia at admission have a higher probability of pediatric intensive care admission than patients without mucocutaneous symptoms.

Shock and Myocardial Injury in Children With Multisystem Inflammatory Syndrome Associated With SARS-CoV-2 Infection: What We Know. Case Series and Review of the Literature.

BACKGROUND: Multisystem inflammatory syndrome associated with SARS-CoV-2 infection can lead to myocardial injury and shock in children, likely the result of a severe inflammatory state, and can mimic Kawasaki disease. OBJECTIVE: To describe the characteristics of shock and myocardial injury in children with confirmed or suspeted COVID-19 during the SARS-CoV-2 pandemic in Spain, including clinical presentation, laboratory and imaging findings, treatment, disease course, and outcome. An extensive literature review is provided. METHODS: Retrospective case series including all children (age 1 month-18 years) admitted to a pediatric intensive care unit in Madrid, Spain, between March 15 and April 30, 2020 with suspected or confirmed SARS-CoV-2 infection and shock. RESULTS: Twelve previously healthy patients with shock, age 5 to 14 years, were included. All required volume resuscitation and 75% required vasoactive/inotropic support. Distributive shock was present on admission in 67% (n = 8), and 4 patients (33%) showed features of cardiogenic shock. Myocardial injury was diagnosed in 67% (n = 8) and ventricular dysfunction in 33% (n = 4). The most common symptoms on presentation were fever (100%), anorexia (100%), diarrhea (75%), and vomiting (75%). Five patients showed signs of Kawasaki disease but none met the criteria for the classic form. Laboratory findings revealed lymphopenia (83%), thrombocytopenia (83%), and increased inflammatory markers (100%). Respiratory status was not significantly impacted. Chest X-ray showed bilateral alveolar infiltrates in 7 (58%) and bilateral pneumonia in 3 (25%). COVID-19 was confirmed in 11 cases (92%). All received empirical therapy against COVID-19, thromboprophylaxis and immunomodulation. Median stay in the PICU and inpatient ward was 4.5 and 10 days, respectively. No patients died. CONCLUSION: Multisystem inflammatory syndrome in children with COVID-19 can mimic Kawasaki disease and lead to a combination of distributive and cardiogenic shock, probably secondary to a hyperinflammatory state that remains to be precisely defined. Treatment strategies include hemodynamic support, empirical therapies against COVID-19, thromboprophylaxis, and immunomodulation.

Children in Critical Care Due to Severe Acute Respiratory Syndrome Coronavirus 2 Infection: Experience in a Spanish Hospital.

OBJECTIVES: Spain has been one of the countries most severely affected by the coronavirus disease 2019. This study aims to describe a series of children admitted to a PICU due to coronavirus disease 2019 infection. DESIGN: Prospective observational study. SETTING: Tertiary hospital in Madrid, Spain. PATIENTS: Children admitted to the PICU with severe acute respiratory syndrome coronavirus 2 (severe acute respiratory syndrome coronavirus 2) infection, from March 1, 2020, to April 15, 2020. INTERVENTIONS: Observational study. MEASUREMENTS AND MAIN RESULTS: Epidemiologic data, previous clinical characteristics, support therapy needed, imaging tests, laboratory observations on admission, and pharmacologic therapy. Eleven children were admitted to the PICU, with suspected coronavirus disease 2019; the polymerase chain reaction test was positive in seven. The median age was 100.7 months (range, 0.5-162). Five were admitted from the emergency department and two from the ward. The Pediatric Sequential Organ Failure Assessment score was 3 (range, 0-9), and Pediatric Risk of Mortality II score was 4 (range, 0-16). All children were previously healthy except one (allogeneic hematopoietic stem cell transplantation). Respiratory symptoms and fever were prevalent. A chest radiograph led to a pneumonia diagnosis. Not all patients presented with lymphopenia on admission. D-Dimer and ferritin were elevated. All patients needed oxygen therapy through a nasal cannula; five patients received high-flow nasal cannula therapy, which was later substituted with noninvasive ventilation in four. Mechanical ventilation was necessary in two patients on the first day of PICU admission. Two children required mechanical ventilation and inotropic support. Tocilizumab was applied in two intubated children. Also, four children received heparin. No patients died. CONCLUSIONS: On the whole, the children were previously healthy and are more than 1 year old. Respiratory symptoms were the leading cause of PICU admission, making respiratory support the principal therapy. Patients requiring mechanical ventilation showed deterioration on the first day of admission. These children seemed to require close monitoring, and multicenter studies are necessary.

Respiratory Failure in Children With Hemato-oncological Diseases Admitted to the PICU: A Single-center Experience.

Respiratory failure (RF) is a main cause of pediatric intensive care unit (PICU) admission in children with hemato-oncological diseases. We present a retrospective chart review of children admitted to our PICU because of RF (January 2006 to December 2010). The aims of this study are the following: (1) to describe the demographical and clinical characteristics and respiratory management of these children; and (2) to identify the factors associated with mechanical ventilation (MV) and mortality. A total of 69 patients, encompassing 88 episodes, were included (55/88 cases were hypoxemic RF). The first respiratory support at PICU admission was, in decreasing order of frequency, high-flow oxygen nasal cannula (HFNC; 50/88), noninvasive ventilation (NIV; 13/88), and oxygen nasal cannula (16/88). MV was necessary in 47/88 episodes, 38/47 after another respiratory support. In 18/28 children with initial NIV, MV was required later. MV was associated with O-PRISM score, NIV requirement, suspected respiratory infection, and days of PICU treatment. Patients without MV showed an increased survival rate (P=0.001). In summary, the hypoxemic RF was the main cause of PICU admission, and HFNC or NIV was almost always the first respiratory support. The use of MV was associated with a higher mortality rate. The utility of precocious HFNC or NIV should be investigated in larger clinical studies.

Management of unstable pediatric hemato-oncology patient: results of a Web-based survey to pediatric oncologists in Spain.

UNLABELLED: The current management and monitoring of unstable pediatric hemato-oncology patient (UPHOP) in the oncology ward is not well defined. To evaluate this concept, an anonymous Web-based survey was sent to the 150 Spanish pediatric oncologists registered in the Spanish Society of Pediatric Hemato-Oncology. The response rate was 57 %, with the following main results: Pediatric intensive consulting was available for 97 %, and it was made in case of UPHOP by 37 % of oncologists, up to 65 % if hemodynamic instability. In case of inotropic support initiation, 32 % of respondents never consulted the intensivist. Dopamine is first chosen inotropic; 28 % of surveyed considered there is no limit in its dosage or it is superior to 20 µg/kg/min before an intensivist consulting. Pediatric intensive care admission was considered necessary in case of fever with hemodynamic instability by 15 % of respondents. Respiratory monitoring was mainly done by clinical signs (67 %). In case of respiratory insufficiency, the noninvasive respiratory support by high-flow ventilation with nasal cannula was applied by 57 % in the oncology ward. In case of acute kidney injury, diuretics were generally the initial therapy. The anticonvulsive drugs most frequently applied were valproic acid (93 %), diazepam (88 %), and phenytoin (81 %). CONCLUSION: A consensus should be achieved among oncologists and intensivists. The creation and training of rapid response teams could be useful to improve the UPHOP management.

Uterus Transplantation as a Surgical Innovation.

Uterus transplantation (UTx) research has been introduced in several countries, with trials in Sweden and the United States producing successful outcomes. The growing interest in developing UTx trials in other countries, such as Spain, the Netherlands, Japan, and Australia, raises important questions regarding the ethics of surgical innovation research in the field of UTx. This paper examines the current state of UTx in the context of the surgical innovation paradigm and IDEAL framework and discusses the ethical challenges faced by those considering the introduction of new trials. We argue that UTx remains an experimental procedure at a relatively early stage of the IDEAL framework, especially in the context of de novo trials, where protocols are likely to deviate from those used previously and where researchers are likely to have limited experience of UTx. We conclude that countries considering the introduction of UTx trials should build on the strengths of the reported outcomes to consolidate the evidence base and shed light on the uncertainties of the procedure. Authorities responsible for the ethical governance of UTx trials are advised to draw on the ethical framework used in the oversight of surgical innovation.

High-flow nasal cannula and non-invasive mechanical ventilation in pediatric asthma exacerbation: two-year prospective observational study in intensive care.

BACKGROUND: Asthma is a common cause of admission to the pediatric intensive care unit (PICU). We described and analyzed the therapies applied to children admitted to a tertiary PICU because of asthma. Later, we evaluated high-flow nasal cannula (HFNC) use in these patients and compared their evolution and complications with those who received non-invasive ventilation. METHODS: We conducted a prospective observational study (October 2017-October 2019). Collected data: epidemiological, clinical, respiratory support therapy needed, complementary tests, and PICU and hospital stay. Patients were divided into three groups: (1) only HFNC; (2) HFNC and non-invasive mechanical ventilation (NIMV); and (3) only NIMV. RESULTS: Seventy-six patients were included (39 female). The median age was 2 years and 1 month. The median pulmonary score was 5. The median PICU stay was 3 days, and the hospital stay was 6 days. Children with HNFC only (56/76) had fewer PICU days (p = 0.025) and did not require NIMV (6/76). Children with HFNC had a higher oxygen saturation/fraction of inspired oxygen ratio ratio (p = 0.025) and lower PCO2 (p = 0.032). In the group receiving both therapies (14/76), NIMV was used first in all cases. No epidemiologic or clinical differences were found among groups. CONCLUSION: HFNC was a safe approach that did not increase the number of PICU or hospital days. On admission, normal initial blood gases and the absence of high oxygen requirements were useful in selecting responders to HFNC. Further randomized and multicenter clinical trials are needed to verify these data.

INTRODUCCIÓN: El asma es una causa frecuente de ingreso en la unidad de cuidados intensivos pediátricos (UCIP). En este, cuadro el uso de cánula nasal de alto flujo (CNAF) se ha visto extendido. En este trabajo se describe el tratamiento global en la UCIP ante el ingreso por asma en un hospital monográfico pediátrico y se evalúa la respuesta al uso de la CNAF, comparando la evolución de los pacientes con aquellos que recibieron ventilación no invasiva (VNI). MÉTODOS: Se llevó a cabo un estudio observacional prospectivo (de octubre del 2017 a octubre del 2019). Se describieron epidemiología, clínica, tratamiento y soporte respiratorio. Para la comparación se crearon tres grupos de pacientes: 1) solo CNAF; 2) CNAF y VNI; y 3) solo VNI. RESULTADOS: Se incluyeron 76 pacientes. La mediana de edad fue de dos años y un mes; la mediana de índice pulmonar fue 5. La mediana de ingreso en UCIP fue de tres días y de ingreso hospitalario, seis días. Los niños con solo CNAF (56/76) mostraron menos días de UCIP (p = 0.025) y no requirieron VNI (6/76). También mostraron mayor SatO2/FiO2 (saturación de oxígeno/fracción de oxígeno inspirado) (p = 0.025) y menor nivel de PCO2 (presión parcial de CO2) (p = 0.032). La VNI se utilizó primero siempre en el grupo que recibió ambas modalidades (14/76). No se encontraron diferencias epidemiológicas o clínicas entre grupos. CONCLUSIONES: En nuestra serie, el uso de CNAF no aumentó los días de ingreso en la UCIP ni de hospital. Tampoco requirió cambio a VNI. Al ingreso, una gasometría normal y bajo requerimiento de oxígeno permitieron seleccionar a los pacientes respondedores. Se necesitan más ensayos multicéntricos clínicos aleatorizados para verificar estos datos.

Increase in Incidence Rates and Risk Factors for Multidrug Resistant Bacteria in Septic Children: A Nationwide Spanish Cohort Study (2013-2019).

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.

Device Exposure and Patient Risk Factors' Impact on the Healthcare-Associated Infection Rates in PICUs.

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.

Antimicrobial Stewardship Improvement in Pediatric Intensive Care Units in Spain-What Have We Learned?

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.

PIMS-TS immunophenotype: description and comparison with healthy children, Kawasaki disease and severe viral and bacterial infections.

BACKGROUND: A new clinical syndrome named Paediatric Inflammatory Multisystem Syndrome Temporally Associated with SARS-CoV-2 (PIMS-TS) has been described. This new disease is a leading cause of hospital and paediatric intensive care unit (PICU). It has been related to immunity dysregulation. METHODS: Prospective-retrospective observational study to describe the innate cell signature and immunophenotype of children admitted to PICU because of PIMS-TS (from March 2020 to September 2020). The immunophenotype was done through the expression analysis of these proteins of mononuclear cells: CD64, CD18, CD11a and CD11b. They were compared with previous healthy controls and children admitted to PICU because of bacterial infection, viral infection and Kawasaki disease (KD). Two hundred and forty-seven children were studied: 183 healthy controls, 25 viral infections, 20 bacterial infections, 6 KD and 13 PIMS-TS. RESULTS: PIMT-TS showed the lowest percentage of lymphocytes and monocytes with higher relative numbers of CD4+ (p = .000). Monocytes and neutrophils in PIMS-TS showed higher levels of CD64 expression (p = .000). Also, CD11a and CD11b were highly expressed (p =,000). CONCLUSION: We observed a differential cell innate signature in PIMS-TS. These findings are consistent with a proinflammatory status (CD64 elevated expression) and lymphocyte trafficking to tissues (CD11a and CD11b). More studies should be carried out to confirm our results.

Usefulness of pneumococcal antigen detection in pleural effusion for the rapid diagnosis of infection by Streptococcus pneumoniae.

Pleural effusion is increasingly reported in children. Standard culture of blood or pleural fluid is frequently negative and molecular diagnosis by polymerase chain reaction is not available in all hospitals. The Binax NOW Streptococcus pneumoniae Antigen test (Binax, Portland, USA) is a rapid immunochromatographic test (ICT) for the detection of the C polysaccharide antigen. We evaluated the Binax NOW test on the pleural fluid of 73 children hospitalized with pleural effusion over a period of 4 years. In our sample, the sensitivity and specificity of ICT were high (88% and 71%, respectively), with a positive predictive value of 96%. Detection of the pneumococcal antigen in pleural fluid by ICT is easy and quick, and enables us to identify the pneumococcal origin of the effusion, thus, making the treatment of complicated pneumonia suitably and early.

sRAGE as severe acute bronchiolitis biomarker, prospective observational study.

INTRODUCTION AND OBJECTIVES: Acute bronchiolitis (AB) is the leading cause of hospitalization in infants and around 5% require intensive care treatment. Early identification of children diagnosed with AB at a high risk of severe progression is of great interest. The receptor for advanced glycation end products (RAGE), highly expressed in lung tissue, regulates immune responses and inflammation, and its soluble form, sRAGE, is believed to have an anti-inflammatory role. We hypothesized serum sRAGE might be a major determinant of AB severity and prognosis. This study was conducted to measure serum sRAGE in infants with severe AB and to assess its correlation with clinical severity, immediate complications, and outcome. METHODS: Single-center, prospective, observational study of hospitalized children with severe bronchiolitis admitted to the Pediatric Intensive Care Unit (PICU), from September 2015 to September 2016. RESULTS: A total of 52 children and 27 controls were included. The cases age ranged from 11 days to 21 months, resulting in a significant age difference with controls (11.85 vs 4.84 months, P < .01). Serum levels of sRAGE were lower but not significant in severe AB patients than in controls (1350.93 vs 1450.42 pg/mL; P = .399). No correlation was found between serum sRAGE and causative viruses, clinical symptoms, Wood-Downes score (a clinical severity score) on admission, respiratory support, or length of hospital stay. Serum sRAGE was also lower in the cases having had a previous respiratory disease (1463.84 vs 1072.43 pg/mL; P = .049). However, it was higher in patients with any lung consolidation on the chest X-ray (1584.79 vs 1131.62 pg/mL; P = .044) and weakly positively correlated with classical biomarkers (maximum C-reactive protein, +0.295, P = .034; maximum procalcitonin, +0.309; P = .029). CONCLUSION: This single-center study reveals that sRAGE couldn't predict AB severity or outcome in children hospitalized at PICU. Nevertheless, it significantly increased in the presence of any lung consolidation and had a positive correlation with classical biomarkers. The utility of sRAGE in this population could be probably elucidated with a better understanding of AGE-RAGE axis.

Severe SARS-CoV-2 Infection in Children With Suspected Acute Abdomen: A Case Series From a Tertiary Hospital in Spain.

We describe 5 children with severe SARS-CoV-2 infection, hemodynamic instability and suspected acute abdomen. This form of the disease has not been previously documented. Four of the cases were confirmed SARS-CoV-2 infection and 1 probable. All of them were previously healthy and needed a pediatric critical care unit admission. The respiratory symptoms were not dominant or were absent. Also, fever was observed. Laboratory testing revealed lymphopenia and high levels of C-reactive protein and procalcitonin with D-dimer, ferritin and interleukin-6 usually elevated. Respiratory support and inotropic support were almost always necessary. In all of them, deterioration occurred on the day of admission.

High-flow nasal cannula and non-invasive mechanical ventilation in pediatric asthma exacerbation: two-year prospective observational study in intensive care / Cánula nasal de alto flujo y ventilación no invasiva en asma pediátrico grave: estudio observacional prospectivo de dos años de duración en cuidados intensivos

Enucleation Caused by Fusarium Infection in a Child With Toxic Epidermal Necrolysis.

Fusarium species are a known cause of ocular infection that can produce local and/or systemic invasive fusariosis. Fusarium ocular infection can evolve to keratitis, endophthalmitis and, in extreme cases, ocular perforation. We report, for the first time in children, the case of a 5 year old girl diagnosed with toxic epidermal necrolysis who developed Fusarium ocular infection requiring ocular enucleation.

Set of Quality Indicators of Pediatric Intensive Care in Spain: Delphi Method Selection.

INTRODUCTION: This study objective was to identify, select, and define a basic set of quality indicators for pediatric intensive care in Spain. METHODS: (1) Review of the literature to identify quality indicators and their defining elements and (2) selection of indicators by consensus of a group of experts using basic Delphi methodology (2 rounds) and forms distributed by email among experts from the Spanish society of pediatric intensive care. RESULTS: We selected quality indicators according to their relevance and feasibility and the experts' agreement on their incorporation in the final set. We included only those indicators whose assessment was within the highest tertile and greater than or equal to 70% evaluator agreement in the final selection. Starting from an initially proposed set of 136 indicators, 31 experts first selected 43 indicators for inclusion in the second round. Twenty indicators were selected for the final set. This "top 20" set comprised 9 process indicators, 9 of results (especially treatment-associated adverse effects), and 2 indicators of structure. Several of them are classical indicators in intensive care medicine (rates of hospital-acquired infections, pressure ulcers, etc.), whereas others are specifically pediatric (eg, unrestricted parent visitation or training the parents of technology-dependent children). CONCLUSIONS: We reached a consensus on a set of 20 essential quality indicators for pediatric intensive care in Spain. A significant subset reflects the peculiarities of pediatric care. We consider this subset as a starting point for future projects of network collaboration between pediatric intensive care units in Spain.
