Impact of COVID-19-related restricted family presence policies on Canadian pediatric intensive care unit clinicians: a qualitative study.

PURPOSE: Pediatric intensive care units (PICUs) worldwide restricted family presence in response to the COVID-19 pandemic. We aimed to explore the experiences and impact of restricted family presence policies on Canadian PICU clinicians. METHODS: We conducted a qualitative study that followed an interpretive phenomenological design. Participants were PICU clinicians providing direct patient care in Canada during periods of COVID-19-related restricted family presence. We purposively sampled for maximum variation among survey participants who consented to be contacted for further research on the same topic. In-depth interviews were conducted remotely via telephone or video-call, audio-recorded, and transcribed. Interviews were inductively coded and underwent thematic analysis. Proposed themes were member-checked by interviewees. RESULTS: Sixteen PICU clinicians completed interviews. Interviewees practiced across Canada, represented a range of disciplines (eight nurses, two physicians, two respiratory therapists, two child life specialists, two social workers) and years in profession (0-34 years). We identified four themes representing the most meaningful aspects of restricted family presence for participants: 1) balancing infection control and family presence; 2) feeling disempowered by hospital and policy-making hierarchies; 3) empathizing with family trauma; and 4) navigating threats to the therapeutic relationship. CONCLUSION: Pediatric intensive care unit clinicians were impacted by restricted family presence policies during the COVID-19 pandemic. These policies contributed to feelings of disempowerment and challenged clinicians' perceived ability to provide the best family-centred care possible. Frontline expertise should be incorporated into the design and implementation of policies to best support family-centred care in any context and minimize risks of moral distress for PICU clinicians.

RéSUMé: OBJECTIF: Les unités de soins intensifs pédiatriques (USIP) du monde entier ont restreint la présence des familles en réponse à la la pandémie de COVID-19. Notre objectif était d'explorer les expériences et l'impact des politiques de restriction de la présence familiale sur les clinicien·nes des USIP canadiennes. MéTHODE: Nous avons mené une étude qualitative qui a suivi un plan phénoménologique interprétatif. Les participant·es étaient des clinicien·nes des USIP qui dispensaient des soins directs aux patient·es au Canada pendant les périodes de présence restreinte des familles en raison de la COVID-19. Nous avons délibérément échantillonné pour obtenir une variation maximale parmi les participant·es à l'enquête qui ont accepté d'être contacté·es pour d'autres recherches sur le même sujet. Des entretiens approfondis ont été menés à distance par téléphone ou par appel vidéo, enregistrés et transcrits. Les entretiens ont été codés de manière inductive et ont fait l'objet d'une analyse thématique. Les thèmes proposés ont été contrôlés par membre par les personnes interrogées. RéSULTATS: Seize cliniciennes et cliniciens des USIP ont passé des entrevues. Les personnes interrogées exerçaient partout au Canada, représentaient un éventail de disciplines (huit infirmiers et infirmières, deux médecins, deux inhalothérapeutes, deux spécialistes du milieu de l'enfant, deux travailleuses et travailleurs sociaux) et d'années d'expérience professionnelle (de 0 à 34 ans). Nous avons identifié quatre thèmes représentant les aspects les plus significatifs de la présence restreinte de la famille pour les participant·es : 1) l'équilibre entre la prévention des infections et la présence de la famille; 2) le sentiment d'être dépossédé·e par les hiérarchies de l'hôpital et de ne pas pouvoir participer à l'élaboration des politiques; 3) le sentiment d'empathie à l'égard des traumatismes familiaux; et 4) la réponse aux menaces qui ont pesé sur la relation thérapeutique. CONCLUSION: Les cliniciens et cliniciennes des unités de soins intensifs pédiatriques ont été touché·es par les politiques de restriction de la présence familiale pendant la pandémie de COVID-19. Ces politiques ont contribué à un sentiment d'impuissance et ont remis en question la capacité perçue des équipes à fournir les meilleurs soins possibles axés sur la famille. L'expertise de première ligne devrait être intégrée à la conception et à la mise en œuvre des politiques afin de mieux soutenir les soins axés sur la famille dans n'importe quel contexte et de minimiser les risques de détresse morale pour les cliniciennes et cliniciens des USIP.

Measuring Energy Requirements of Traumatic Brain Injury Patients in Pediatric Intensive Care With Indirect Calorimetry: A Comparison With Empiric Methods.

OBJECTIVES: Energy requirements following moderate or severe pediatric traumatic brain injury (TBI) have not been fully elucidated. Indirect calorimetry (IC) is the gold standard for measuring resting energy expenditure (MREE) in PICU. However, technical complexity limits its use. We aimed to determine whether MREE differs from standard of care energy estimation and delivery in a cohort of pediatric patients following moderate to severe TBI during PICU admission. DESIGN: Retrospective case series study. SETTING: Single-center, 16-bed general PICU in Canada between May 2011 and January 2019. PATIENTS: Children (0-18 yr) admitted to a PICU for moderate (Glasgow Coma Scale [GCS] 9-12) to severe TBI (GCS < 9) and had an IC study performed while mechanically ventilated. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the study period, 245 patients were admitted with the diagnosis of trauma with TBI. The study includes a convenience sample of 26 patients with severe ( n = 23) and moderate ( n = 3) TBI who underwent a total of 34 IC measurements. MREE varied considerably from 29% to 144% of predicted energy expenditure. Using Bland-Altman comparative analysis, neither Schofield nor World Health Organization predictive equations were in agreement with MREE. Only one measurement revealed that the patient was appropriately fed (energy provided in nutrition support was within 10% of MREE); 10 (38%) measurements revealed overfeeding and 15 (58%) underfeeding at the time of testing. CONCLUSIONS: The present study adds to the small body of literature highlighting the limitations of predictive equations to evaluate energy requirements following moderate to severe pediatric TBI. IC, when feasible, should be used as the preferred method to orient PICU teams to feed such vulnerable patients.

A survey of pediatric intensive care unit clinician experience with restricted family presence during COVID-19.

PURPOSE: Limiting family presence runs counter to the family-centred values of Canadian pediatric intensive care units (PICUs). This study explores how implementing and enforcing COVID-19-related restricted family presence (RFP) policies impacted PICU clinicians nationally. METHODS: We conducted a cross-sectional, online, self-administered survey of Canadian PICU clinicians to assess experience and opinions of restrictions, moral distress (Moral Distress Thermometer, range 0-10), and mental health impacts (Impact of Event Scale [IES], range 0-75 and attributable stress [five-point Likert scale]). For analysis, we used descriptive statistics, multivariate regression modelling, and a general inductive approach for free text. RESULTS: Representing 17/19 Canadian PICUs, 368 of 388 respondents (94%) experienced RFP policies and were predominantly female (333/368, 91%), English speaking (338/368, 92%), and nurses (240/368, 65%). The mean (standard deviation [SD]) reported moral distress score was 4.5 (2.4) and was associated with perceived differential impact on families. The mean (SD) total IES score was 29.7 (10.5), suggesting moderate traumatic stress with 56% (176/317) reporting increased/significantly increased stress from restrictions related to separating families, denying access, and concern for family impacts. Incongruence between RFP policies/practices and PICU values was perceived by 66% of respondents (217/330). Most respondents (235/330, 71%) felt their opinions were not valued when implementing policies. Though respondents perceived that restrictions were implemented for the benefit of clinicians (252/332, 76%) and to protect families (236/315, 75%), 57% (188/332) disagreed that their RFP experience was mainly positive. CONCLUSION: Pediatric intensive care unit-based RFP rules, largely designed and implemented without bedside clinician input, caused increased psychological burden for clinicians, characterized as moderate moral distress and trauma triggered by perceived impacts on families.

RéSUMé: OBJECTIF: Limiter la présence de la famille va à l'encontre des valeurs centrées sur la famille des unités de soins intensifs pédiatriques (USIP) canadiennes. Cette étude explore comment la mise en œuvre et l'application des politiques de restriction de la présence familiale liées à la COVID-19 ont eu une incidence sur les cliniciennes et cliniciens des USIP à l'échelle nationale. MéTHODE: Nous avons mené un sondage transversal, en ligne et auto-administré auprès des cliniciens et cliniciennes des USIP canadiennes afin d'évaluer leur expérience et opinions sur les restrictions, la détresse morale (thermomètre de détresse morale, intervalle de 0 à 10) et les impacts sur la santé mentale (échelle d'impact des événements [EIE], intervalle de 0 à 75, et le stress qui peut y être attribué [échelle de Likert à cinq points]). Pour l'analyse, nous avons utilisé des statistiques descriptives, une modélisation de régression multivariée et une analyse inductive générale pour le texte libre. RéSULTATS: Représentant 17/19 USIP canadiennes, 368 des 388 personnes répondantes (94 %) ont vécu des politiques de restriction de la présence familiale et étaient principalement des femmes (333/368, 91 %), anglophones (338/368, 92 %) et infirmières (240/368, 65 %). Le score moyen (écart type [ET]) rapporté de détresse morale était de 4,5 (2,4) et était associé à l'impact différentiel perçu sur les familles. Le score moyen (ET) total de l'EIE était de 29,7 (10,5), ce qui suggère un stress traumatique modéré, 56 % (176/317) des personnes répondantes déclarant une augmentation ou une augmentation significative du stress associé aux restrictions liées à la séparation des familles, au refus d'accès et à la préoccupation pour les impacts familiaux. L'incongruité entre les politiques et les pratiques de restriction des visites familiales et les valeurs des USIP était perçue par 66 % des personnes répondantes (217/330). La plupart (235/330, 71 %) estimaient que leurs opinions n'étaient pas prises en compte lors de la mise en œuvre de politiques. Bien que les répondant·es aient perçu que les restrictions avaient été mises en œuvre dans l'intérêt des cliniciens et cliniciennes (252/332, 76 %) et pour protéger les familles (236/315, 75 %), 57 % (188/332) n'étaient pas d'accord pour dire que leur expérience de la restriction des visites familiales était principalement positive. CONCLUSION: Les règles de restriction de la présence familiale dans les unités de soins intensifs pédiatriques, en grande partie conçues et mises en œuvre sans l'avis du personnel clinique au chevet des patient·es, ont entraîné une augmentation du fardeau psychologique pour le personnel clinique, caractérisée par une détresse morale modérée et un traumatisme déclenché par des répercussions perçues sur les familles.

Designing a national pediatric critical care database: a Delphi consensus study.

PURPOSE: We sought to describe the processes undertaken for the systematic selection and consensus determination of the common data elements for inclusion in a national pediatric critical care database in Canada. METHODS: We conducted a multicentre Delphi consensus study of Canadian pediatric intensive care units (PICUs) participating in the creation of a national database. Participants were PICU health care professionals, allied health professionals, caregivers, and other stakeholders. A dedicated panel group created a baseline survey of data elements based on literature, current PICU databases, and expertise in the field. The survey was then used for a Delphi iterative consensus process over three rounds, conducted from March to June 2021. RESULTS: Of 86 invited participants, 68 (79%) engaged and agreed to participate as part of an expert panel. Panel participants were sent three rounds of the survey with response rates of 62 (91%), 61 (90%) and 55 (81%), respectively. After three rounds, 72 data elements were included from six domains, mostly reflecting clinical status and complex medical interventions received in the PICU. While race, gender, and home region were included by consensus, variables such as minority status, indigenous status, primary language, and ethnicity were not. CONCLUSION: We present the methodological framework used to select data elements by consensus for a national pediatric critical care database, with participation from a diverse stakeholder group of experts and caregivers from all PICUs in Canada. The selected core data elements will provide standardized and synthesized data for research, benchmarking, and quality improvement initiatives of critically ill children.

RéSUMé: OBJECTIF: Nous avons cherché à décrire les processus entrepris pour la sélection systématique et la détermination consensuelle des éléments de données communs à inclure dans une base de données nationale sur les soins intensifs pédiatriques au Canada. MéTHODE: Nous avons mené une étude multicentrique de consensus selon la méthode Delphi sur les unités de soins intensifs pédiatriques (USIP) canadiennes participant à la création d'une base de données nationale. Les personnes participant à l'étude étaient des professionnel·les de la santé de l'USIP, du personnel paramédical, des soignant·es et d'autres intervenant·es. Un groupe de travail spécialisé a créé une enquête de base des éléments de données sur la littérature, les bases de données actuelles portant sur les USIP et l'expertise dans le domaine. L'enquête a ensuite été utilisée pour créer un processus de consensus itératif Delphi sur trois cycles, mené de mars à juin 2021. RéSULTATS: Sur les 86 personnes invitées à participer, 68 (79 %) se sont engagées et ont accepté de participer à un groupe d'experts. Les membres du panel ont reçu trois rondes du sondage, avec des taux de réponse de 62 (91 %), 61 (90 %) et 55 (81 %), respectivement. Après trois cycles, 72 éléments de données provenant de six domaines ont été inclus, reflétant principalement l'état clinique et les interventions médicales complexes reçues à l'USIP. Alors que la race, le genre et la région d'origine ont été inclus par consensus, des variables telles que le statut de minorité, le statut d'autochtone, la langue principale parlée et l'origine ethnique ne l'ont pas été. CONCLUSION: Nous présentons le cadre méthodologique utilisé pour sélectionner des éléments de données consensuels destinés à une base de données nationale sur les soins intensifs pédiatriques, avec la participation d'un groupe diversifié d'expert·es et de soignant·es de toutes les USIP au Canada. Les éléments de données de base sélectionnés fourniront des données normalisées et synthétisées pour la recherche, l'analyse comparative et les initiatives d'amélioration de la qualité pour les enfants gravement malades.

Hastening Death in Canadian ICUs: End-of-Life Care in the Era of Medical Assistance in Dying.

OBJECTIVES: Since 2016, Canada has allowed for euthanasia based on strict criteria under federal medical assistance in dying legislation. The purpose of this study was to determine how Canadian intensivists perceive medical assistance in dying and whether they believe their approach to withdrawal of life-sustaining therapies has changed following introduction of medical assistance in dying. DESIGN: Electronic survey. SETTING: Participants were recruited from 11 PICU programs and 14 adult ICU programs across Canada. All program leaders for whom contact information was available were approached for participation. PARTICIPANTS: We invited intensivists and critical care trainees employed between December 2019 and May 2020 to participate using a snowball sampling technique in which department leaders distributed study information. All responses were anonymous. Quantitative data were analyzed using descriptive statistics. Categorical variables were analyzed using Pearson chi-square test. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: We obtained 150 complete questionnaires (33% response rate), of which 50% were adult practitioners and 50% pediatric. Most were from academic centers (81%, n = 121). Of respondents, 86% (n = 130) were familiar with medical assistance in dying legislation, 71% in favor, 14% conflicted, and 11% opposed. Only 5% (n = 8) thought it had influenced their approach to withdrawal of life-sustaining therapies. Half of participants had no standardized protocol for withdrawal of life-sustaining therapies in their unit, and 41% (n = 62) had observed medications given in disproportionately high doses during withdrawal of life-sustaining therapies, with 13% having personally administered such doses. Most (80%, n = 120) had experienced explicit requests from families to hasten death, and almost half (47%, n = 70) believed it was ethically permissible to intentionally hasten death following withdrawal of life-sustaining therapies. CONCLUSIONS: Most Canadian intensivists surveyed do not think that medical assistance in dying has changed their approach to end of life in the ICU. A significant minority are ethically conflicted about the current approach to assisted dying/euthanasia in Canada. Almost half believe it is ethical to intentionally hasten death during withdrawal of life-sustaining therapies if death is expected.

Association Between Acute Kidney Injury Duration and Outcomes in Critically Ill Children.

OBJECTIVES: Acute kidney injury occurs frequently in children during critical illness and is associated with increased morbidity, mortality, and health resource utilization. We aimed to examine the association between acute kidney injury duration and these outcomes. DESIGN: Retrospective cohort study. SETTINGS: PICUs in Alberta, Canada. PATIENTS: All children admitted to PICUs in Alberta, Canada between January 1, 2015, and December 31, 2015. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: In total, 1,017 children were included, and 308 (30.3%) developed acute kidney injury during PICU stay. Acute kidney injury was categorized based on duration to transient (48 hr or less) or persistent (more than 48 hr). Transient acute kidney injury occurred in 240 children (77.9%), whereas 68 children (22.1%) had persistent acute kidney injury. Persistent acute kidney injury had a higher proportion of stage 2 and stage 3 acute kidney injury compared with transient acute kidney injury and was more likely to start within 24 hours from PICU admission. Persistent acute kidney injury occurred more frequently in those with higher illness severity and in those admitted with shock, sepsis, or with a history of transplant. Mortality varied significantly according to acute kidney injury status: 1.8% of children with no acute kidney injury, 5.4% with transient acute kidney injury, and 17.6% with persistent acute kidney injury died during hospital stay (p < 0.001). On multivariable analysis adjusting for illness and acute kidney injury severity, transient and persistent acute kidney injury were both associated with fewer ventilation-free days at 28 days (-1.28 d; 95% CI, -2.29 to -0.26 and -4.85 d; 95% CI, -6.82 to -2.88), vasoactive support-free days (-1.07 d; 95% CI, -2.00 to -0.15 and -4.24 d; 95% CI, -6.03 to -2.45), and hospital-free days (-1.93 d; 95% CI, -3.36 to -0.49 and -5.25 d; 95% CI, -8.03 to -2.47), respectively. CONCLUSIONS: In critically ill children, persistent and transient acute kidney injury have different clinical characteristics and association with outcomes. Acute kidney injury, even when its duration is short, carries significant association with worse outcomes. This risk increases further if acute kidney injury persists longer independent of the degree of its severity.

Serum Creatinine Monitoring After Acute Kidney Injury in the PICU.

OBJECTIVES: It is unknown whether children with acute kidney injury during PICU admission have kidney function monitored after discharge. Objectives: 1) describe postdischarge serum creatinine monitoring after PICU acute kidney injury and 2) determine factors associated with postdischarge serum creatinine monitoring. DESIGN: Secondary analysis of longitudinal cohort study data. SETTING: Two PICUs in Montreal and Edmonton, Canada. PATIENTS: Children (0-18 yr old) surviving PICU admission greater than or equal to 2 days from 2005 to 2011. Exclusions: postcardiac surgery and prior kidney disease. Exposure: acute kidney injury by Kidney Disease: Improving Global Outcomes serum creatinine definition. INTERVENTIONS: None. MEASUREMENTS: Primary outcome: postdischarge serum creatinine measured by 90 days, 1 year, and 5-7 years. SECONDARY OUTCOMES: Healthcare events and nephrology follow-up. ANALYSIS: Proportions with outcomes; logistic regression to evaluate factors associated with the primary outcome. Kaplan-Meier analysis of time to serum creatinine measurement and healthcare events. MAIN RESULTS: Of n = 277, 69 (25%) had acute kidney injury; 29/69 (42%), 34/69 (49%), and 51/69 (74%) had serum creatinine measured by 90 days, 1 year, and 5-7 year postdischarge, respectively. Acute kidney injury survivors were more likely to have serum creatinine measured versus nonacute kidney injury survivors at all time points (p ≤ 0.01). Factors associated with 90-day serum creatinine measurement were inpatient nephrology consultation (unadjusted odds ratio [95% CI], 14.9 [1.7-127.0]), stage 2-3 acute kidney injury (adjusted odds ratio, 3.4 [1.1-10.2]), and oncologic admission diagnosis (adjusted odds ratio, 10.0 [1.1-93.5]). A higher proportion of acute kidney injury versus nonacute kidney injury survivors were readmitted by 90 days (25 [36%] vs 44 [21%]; p = 0.01) and 1 year (33 [38%] vs 70 [34%]; p = 0.04). Of 24 acute kidney injury survivors diagnosed with chronic kidney disease or hypertension at 5-7 year follow-up, 16 (67%) had serum creatinine measurement and three (13%) had nephrology follow-up postdischarge. CONCLUSIONS: Half of PICU acute kidney injury survivors have serum creatinine measured within 1-year postdischarge and follow-up is suboptimal for children developing long-term kidney sequelae. Knowledge translation strategies should emphasize the importance of serum creatinine monitoring after childhood acute kidney injury.

Kidney and blood pressure abnormalities 6 years after acute kidney injury in critically ill children: a prospective cohort study.

BACKGROUND: Acute kidney injury (AKI) in pediatric intensive care unit (PICU) children may be associated with long-term chronic kidney disease or hypertension. OBJECTIVES: To estimate (1) prevalence of kidney abnormalities (low estimated glomerular filtration rate (eGFR) or albuminuria) and blood pressure (BP) consistent with pre-hypertension or hypertension, 6 years after PICU admission; (2) if AKI is associated with these outcomes. METHODS: Longitudinal study of children admitted to two Canadian PICUs (January 2005-December 2011). Exposures (retrospective): AKI or stage 2/3 AKI (KDIGO creatinine-based definition) during PICU. Primary outcome (single visit 6 years after admission): presence of (a) low eGFR (<90 ml/min/1.73 m2) or albuminuria (albumin to creatinine ratio >30 mg/g) (termed "CKD signs") or (b) BP consistent with ≥pre-hypertension (≥90th percentile) or hypertension (≥95th percentile). RESULTS: Of 277 children, 25% had AKI. AKI and stage 2/3 AKI were associated with 2.2- and 6.6-fold higher adjusted odds, respectively, for the 6-year outcomes. Applying new hypertension guidelines attenuated associations; stage 2/3 AKI was associated with 4.5-fold higher adjusted odds for 6-year CKD signs or ≥elevated BP. CONCLUSIONS: Kidney and BP abnormalities are common 6 years after PICU admission and associated with AKI. Other risk factors must be elucidated to develop follow-up recommendations and reduce cardiovascular risk.

Follow-up after neonatal heart disease repair: watch out for chronic kidney disease and hypertension!

BACKGROUND: With advances in care, neonates undergoing cardiac repairs are surviving more frequently. Our objectives were to 1) estimate the prevalence of chronic kidney disease (CKD) and hypertension 6 years after neonatal congenital heart surgery and 2) determine if cardiac surgery-associated acute kidney injury (CS-AKI) is associated with these outcomes. METHODS: Two-center prospective, longitudinal single-visit cohort study including children with congenital heart disease surgery as neonates between January 2005 and December 2012. CKD (estimated glomerular filtration rate < 90 mL/min/1.73m2 or albumin/creatinine ≥3 mg/mmol) and hypertension (systolic or diastolic blood pressure ≥ 95th percentile for age, sex, and height) prevalence 6 years after surgery was estimated. The association of CS-AKI (Kidney Disease: Improving Global Outcomes definition) with CKD and hypertension was determined using multiple regression. RESULTS: Fifty-eight children with median follow-up of 6 years were evaluated. CS-AKI occurred in 58%. CKD and hypertension prevalence were 17% and 30%, respectively; an additional 15% were classified as having elevated blood pressure. CS-AKI was not associated with CKD or hypertension. Classification as cyanotic postoperatively was the only independent predictor of CKD. Postoperative days in hospital predicted hypertension at follow-up. CONCLUSIONS: The prevalence of CKD and hypertension is high in children having neonatal congenital heart surgery. This is important; early identification of CKD and hypertension can improve outcomes. These children should be systematically followed for the evolution of these negative outcomes. CS-AKI defined by current standards may not be a useful clinical tool to decide who needs follow-up and who does not.

An International Survey Comparing Different Physician Models for Health Care Delivery to Critically Ill Children With Heart Disease.

OBJECTIVES: To explore relationships between the training background of cardiac critical care attending physicians and self-reported perceived strengths and weaknesses in their ability to provide clinical care. DESIGN: Cross-sectional observational survey sent worldwide to ~550 practicing cardiac ICU attending physicians. SETTING: Hospitals providing cardiac critical care. SUBJECTS: Practicing cardiac critical care physicians. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We received responses from 243 ICU attending physicians from 82 centers (14 countries). The primary training background of the respondents included critical care (62%), dual training in critical care and cardiology (16%), cardiology (14%), and other (8%). We received 49 responses from medical directors in nine countries, who reported that the predominant training background for attending physicians who provide cardiac intensive care at their institutions were critical care (58%), dual trained (18%), cardiology (12%), and other (11%). A greater proportion of physicians trained in either critical care or dual-training reported feeling confident managing multiple organ failure, neurologic conditions, brain death, cardiac arrest, and performing procedures like advanced airway placement and inserting chest- and abdominal-drains. In contrast, physicians with cardiology and dual-training reported feeling more confident managing intractable arrhythmias, understanding cardiopulmonary interactions, and interpreting echocardiogram, electrocardiogram, and cardiac catheterization. Overall, only 57% of the respondents felt comfortable based on their current training background to manage patients with complex cardiac issues without collaboration with other specialists. CONCLUSIONS: Our survey demonstrates that intensivists trained in critical care are more comfortable with critical care skills, cardiology-trained intensivists are more comfortable with cardiology skills, and dual-trained physicians are comfortable with both critical care skills and cardiology skills. These findings may help inform future efforts to optimize the educational curriculum and training pathways for future cardiac intensivists. These data may also be used to shape continuing medical education activities for cardiac intensivists who have already completed their training.

Variation in Practice Related to the Use of High Flow Nasal Cannula in Critically Ill Children.

OBJECTIVES: To determine current management of critically ill children and gather views regarding high flow nasal cannula therapy and to evaluate research priorities for a large prospective randomized controlled trial of noninvasive respiratory support in children. DESIGN: Multinational cross-sectional questionnaire survey conducted in 2018. SETTING: The sample included pediatric intensive care physicians in North and South America, Asia, Europe, and Australia/New Zealand. MEASUREMENT: Questions consisted of: 1) characteristics of intensivists and hospital, 2) practice of high flow nasal cannula, 3) supportive treatment, and 4) research of high flow nasal cannula. INTERVENTIONS: None. MAIN RESULTS: We collected data from 1,031 respondents; 919 (North America, 215; Australia/New Zealand, 34; Asia, 203; South America, 186; Europe, 281) were analyzed. Sixty-nine percent of the respondents used high flow nasal cannula in non-PICU settings in their institutions. For a case of bronchiolitis/pneumonia infant, 2 L/kg/min of initial flow rate was the most commonly used. For a scenario of pneumonia with 30 kg weight, more than 60% of the respondents initiated flow based on patient body weight; while, 18% applied a fixed flow rate. Noninvasive ventilation was considered as a next step in more than 85% of respondents when the patient is failing with high flow nasal cannula. Significant practice variations were observed in clinical practice markers used, flow weaning strategy, and supportive practices. Views comparing high flow nasal cannula to continuous positive airway pressure also noticeably varied across the respondents. CONCLUSIONS: Significant practice variations including views of high flow nasal cannula compared to continuous positive airway pressure was found among pediatric intensive care physicians. To expedite establishment and standardization of high flow nasal cannula practice, research aimed at understanding the heterogeneity found in this study should be undertaken.

Paucity of renal follow-up by school age after neonatal cardiac surgery.

INTRODUCTION: There are little data about renal follow-up of neonates after cardiovascular surgery and no guidelines for long-term renal follow-up. Our objectives were to assess renal function follow-up practice after neonatal cardiac surgery, evaluate factors that predict follow-up serum creatinine measurements including acute kidney injury following surgery, and evaluate the estimated glomerular filtration rate during follow-up using routinely collected laboratory values. METHODS: Two-centre retrospective cohort study of children 5-7 years of age with a history of neonatal cardiac surgery. Univariable and multivariable analyses were performed to determine factors associated with post-discharge creatinine measurements. Glomerular filtration rate was estimated for each creatinine using a height-independent equation. RESULTS: Seventeen of 55 children (30%) did not have any creatinine measured following discharge after surgery until the end of study follow-up, which occurred at a median time of 6 years after discharge. Of the 38 children who had the kidney function checked, 15 (40%) had all of their creatinine drawn only in the context of a hospitalisation or emergency department visit. Acute kidney injury following surgery did not predict the presence of follow-up creatinine measurements. CONCLUSIONS: A large proportion of neonates undergoing congenital heart repair did not have a follow-up creatinine measured in the first years following surgery. In those that did have a creatinine measured, there did not appear to be any identified pattern of follow-up. A follow-up system for children who are discharged from cardiac surgery is needed to identify children with or at risk of chronic kidney disease.

Care for Dying Children and Their Families in the PICU: Promoting Clinician Education, Support, and Resilience.

OBJECTIVES: To describe the consequences of workplace stressors on healthcare clinicians in PICU, and strategies for personal well-being, and professional effectiveness in providing high-quality end-of-life care. DATA SOURCES: Literature review, clinical experience, and expert opinion. STUDY SELECTION: A sampling of foundational and current evidence was accessed. DATA SYNTHESIS: Narrative review and experiential reflection. CONCLUSIONS: The well-being of healthcare clinicians in the PICU influences the day-to-day quality and effectiveness of patient care, team functioning, and the retention of skilled individuals in the PICU workforce. End-of-life care, including decision making, can be complicated. Both are major stressors for PICU staff that can lead to adverse personal and professional consequences. Overresponsiveness to routine stressors may be seen in those with moral distress, and underresponsiveness may be seen in those with compassion fatigue or burnout. Ideally, all healthcare professionals in PICU can rise to the day-to-day workplace challenges-responding in an adaptive, effective manner. Strategies to proactively increase resilience and well-being include self-awareness, self-care, situational awareness, and education to increase confidence and skills for providing end-of-life care. Reactive strategies include case conferences, prebriefings in ongoing preidentified situations, debriefings, and other postevent meetings. Nurturing a culture of practice that acknowledges the emotional impacts of pediatric critical care work and celebrates the shared experiences of families and clinicians to build resilient, effective, and professionally fulfilled healthcare professionals thus enabling the provision of high-quality end-of-life care for children and their families.

Cardiac Surgery-Associated Kidney Injury in Children and Renal Oximetry.

OBJECTIVES: Cardiac surgery-associated acute kidney injury is common in children and associates with negative outcomes. Novel interventions to reduce cardiac surgery-associated acute kidney injury require knowledge of its pathophysiology. States of altered perfusion, oxygen delivery, and energy consumption occur during cardiopulmonary bypass and could protect against or contribute to renal cellular injury and recovery. Near-infrared spectroscopy is noninvasive technology for monitoring regional blood flow and tissue oxygenation. This study evaluated the relationship between renal regional oxygen saturation and cardiac surgery-associated acute kidney injury, using near-infrared spectroscopy monitoring before, during, and after cardiopulmonary bypass in children. DESIGN: Prospective cohort study. SETTING: Single-center, tertiary care pediatric hospital (Stollery Children's Hospital, Edmonton, AB, Canada). PATIENTS: Children less than or equal to 10 kg undergoing congenital heart disease repair with cardiopulmonary bypass. Heart transplant, preoperative dialysis, sepsis, extracorporeal life support, congenital renal disease, and preoperative nephrotoxins were exclusions. INTERVENTIONS: Renal regional near-infrared spectroscopy monitoring before, during, and after cardiopulmonary bypass. MEASUREMENTS AND MAIN RESULTS: Outcome measure was cardiac surgery-associated acute kidney injury (defined according to Kidney Disease: Improving Global Outcomes criteria). Regional oxygen saturation was measured continuously using near-infrared spectroscopy (INVOS 5100C Cerebral/Somatic Oximeter; Medronic, Troy, MI) from time of anesthesia to time of transfer to intensive care. Cardiac surgery-associated acute kidney injury occurred in 65%. Lower baseline (precardiopulmonary bypass) regional oxygen saturation was associated with decreased risk of cardiac surgery-associated acute kidney injury (p = 0.01); children with baseline regional oxygen saturation in the highest tertile were 7.14 times more likely to get cardiac surgery- associated acute kidney injury (vs lowest tertile). Area under the curve for ability of baseline regional oxygen saturation to predict cardiac surgery-associated acute kidney injury was 0.73 (95% CI, 0.60-0.85). Children with lower baseline glomerular filtration rate had lower mean renal regional oxygen saturation. CONCLUSIONS: Findings demonstrate that preoperative oxygen supply/demand balance is an important predictor of cardiac surgery-associated acute kidney injury, suggesting lower preoperative (and intraoperative) renal blood flow may be protective. There is not yet a definite link between remote ischemic preconditioning and prevention of cardiac surgery-associated acute kidney injury; however, renal protective effects of sublethal ischemia should continue to be explored.

Virus detection in critically ill children with acute respiratory disease: a new profile in view of new technology.

AIM: To describe the epidemiology of critically ill children admitted to a paediatric intensive care unit (PICU) with acute respiratory disease. The association with intubation was analysed for the three most prevalent viruses and in those with and without viral co-infection. METHODS: Patients admitted to the PICU (2004-2014) with acute respiratory disease were included. Analyses were performed utilising each respiratory viral infection or multiple viral infections as an exposure. RESULTS: There were 1766 admissions with acute respiratory disease of which 1372 had respiratory virus testing and 748 had one or more viruses detected. The risk of intubation before or during the PICU stay was higher if parainfluenza virus was detected compared to respiratory syncytial virus (RSV) (OR: 2.20; 95% CI: 1.06-4.56). Sixty-three admissions had two or more viruses detected, and the combination of RSV and Rhinovirus/enterovirus was the most common. No significant difference was observed in the risk of intubation between patients with multiple and single viral infections. CONCLUSION: Higher risk of intubation was found in patients with parainfluenza as compared to RSV. The risk of intubation comparing parainfluenza virus to other viruses and for patients with multiple versus single virus needs to be further studied.

The Clinical Impact of Heated Humidified High-Flow Nasal Cannula on Pediatric Respiratory Distress.

OBJECTIVES: To assess the impact on a single PICU of introducing high-flow nasal cannula as a management tool for respiratory distress. DESIGN: Retrospective cohort study, including an interrupted time series analysis with a propensity score adjustment and a matched-pair analysis. SETTING: A single university-affiliated children's hospital PICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Differences in clinical outcomes when comparing the pre-high-flow nasal cannula era (2004-2008) and the high-flow nasal cannula era (2010-2014), excluding 2009 as a washout period, and clinical impacts of high-flow nasal cannula as an exposure of interest. A total of 1,766 children met the inclusion criteria (pre-high-flow nasal cannula era: 699 patients; high-flow nasal cannula era: 1,067 patients). High-flow nasal cannula was used in 455 patients (42.6%) in the high-flow nasal cannula era. The interrupted time series analysis failed to show a statistically significant difference in PICU length of stay, but the duration of invasive ventilation was shortened by an average of 2.3 days in the high-flow nasal cannula era group (95% CI, 0.2-4.4; p = 0.030). The PICU intubation rate in the high-flow nasal cannula era was 0.72 times that of the pre-high-flow nasal cannula era (95% CI, 0.63-0.84; p < 0.001). A total of 373 pairs were formed for the matched-pair analysis. The odds for being intubated in the PICU for those patients using high-flow nasal cannula was 0.06 (95% CI, 0.02-0.16; p < 0.001) when compared with those who did not use high-flow nasal cannula. The PICU length of stay increased by 2.9 days in those patients in which high-flow nasal cannula was used (95% CI, 1.3-4.4; p < 0.001). CONCLUSIONS: The introduction of high-flow nasal cannula as a therapy for respiratory distress in the PICU was associated with a significant decrease in the PICU intubation rate with no associated change in mortality.

Organizational Influences on Health Professionals' Experiences of Moral Distress in PICUs.

This article reports the findings of a qualitative study (secondary analysis) that explored the organizational influences on moral distress for health professionals working in pediatric intensive care units (PICUs) across Canada. Participants were recruited to the study from PICUs across Canada. The PICU is a high-tech, fast-paced, high-pressure environment where caregivers frequently face conflict and ethical tension in the care of critically ill children. A number of themes including relationships with management, organizational structure and processes, workload and resources, and team dynamics were identified. This study provides a rare and important multi-disciplinary perspective on this topic and the findings have implications for administrators and leaders who seek to improve the moral climate of healthcare delivery.

Comparison of two surgical techniques for complete atrioventricular septal defect repair using two- and three-dimensional echocardiography.

Different surgical techniques for complete atrioventricular septal defect (CAVSD) repair have been described, with the double-patch technique being most frequently employed. More recently a newer technique using a modified single-patch repair has been advocated. We hypothesized that the modified single-patch technique would result in an increased incidence of the two major post-repair comorbidities, namely, distortion of the left AV valve (LAVV) leaflets and narrowing of the left-ventricular outflow tract (LVOT). We studied 14 patients with CAVSD who underwent either traditional double-patch technique [group 1 (n = 7)] or modified single-patch technique [group 2 (n = 7)]. Preoperative and immediate postoperative two-dimensional (2D) echocardiograms, as well as follow-up 2D and three-dimensional (3D) studies, were reviewed. For group 1, the median age at repair was 4.1 months with a median duration from surgical repair and last echocardiogram of 44 months. For group 2, the median age at repair was 3 months with a median duration from surgical repair and last echocardiogram of 28 months. The two groups had similar demographics and ventricular septal defect size before surgery. For the LAVV, no significant difference was observed with respect to LAVV annulus size, tenting height, and the size of the vena contracta. Furthermore, there was no significant difference in the 2D echocardiographic areas and volumes of the LVOT between pre-repair and immediate post-repair studies for both groups. At the last evaluation, although there had been growth of the LVOT in both groups, no significant difference between areas and volumes were observed. Areas of the LVOT measured by 3D echocardiography on the final study showed no significant statistical difference between both groups. There was good correlation of the areas measured by 2D and 3D echocardiography within each group. In this small group, modified single-patch technique does not appear to tether the LAVV or promote an increase in regurgitation. In the short term, LVOT growth is unaffected, and the repair does not promote LVOT obstruction. 3D echocardiography is useful for area measurements of the LVOT and showed good correlation with areas measured by assumption of the LVOT shape as determined using 2D techniques.
