Pediatric Chronic Critical Illness: Gaps in Inpatient Intrateam Communication
Objectives: The number of children with medical complexity and prolonged hospitalizations is rising. Strategies to adapt acute care approaches for this population are falling behind clinical demand. This study aimed to identify how inpatient team communication practices match the needs of teams caring for these patients and families, and to identify priority areas for improvement. Design: Cross-sectional mixed methods survey. Setting: Academic children’s hospital. Subjects: Interdisciplinary healthcare professionals: physicians, nurse practitioners, nurses, resident and fellow trainees, respiratory therapists, clinical pharmacists, occupational therapists, physical therapists, social workers, and child life specialists. Interventions: None. Measurements and Main Results: Four-hundred eight interdisciplinary healthcare professionals participated (33% response rate). Half (53 %) worked in ICUs and 37% had greater than 10 years clinical experience. Three overarching themes emerged regarding communication during care of children with prolonged hospitalizations are as follows: 1) Dysfunctional team collaboration: the many involved healthcare providers for these children have inconsistent team meetings and few platforms for reaching clinical consensus; 2) Continuity gaps: time-limited clinician rotations and no designated longitudinal clinical leaders undermine relationships with families and key elements of shared decision-making; and 3) Inadequate communication skills and tools: healthcare professionals have inadequate training to address complex conversations and big picture concerns, and often default to daily management conversations. Nearly half (40%) perceived intra-team conflict to occur more commonly during care of these children compared with those with short hospitalizations, and many feel unskilled to address these conflicts. Healthcare providers working in ICUs were more likely than other healthcare providers to find care of children with chronic critical illness stressful “most of the time” (ICU 46%; 60/131 vs non-ICU 25%; 21/84; p = 0.02). Conclusions: Acute care inpatient communication practices require modification to meet the needs of healthcare professionals who provide longitudinal care to children with repeated and prolonged hospitalizations. Improvement strategies should prioritize building collaboration, continuity, and communication skills among healthcare professionals.

Performance of a Clinical Decision Support Tool to Identify PICU Patients at High Risk for Clinical Deterioration
Objectives: To evaluate the translation of a paper high-risk checklist for PICU patients at risk of clinical deterioration to an automated clinical decision support tool. Design: Retrospective, observational cohort study of an automated clinical decision support tool, the PICU Warning Tool, adapted from a paper checklist to predict clinical deterioration events in PICU patients within 24 hours. Setting: Two quaternary care medical-surgical PICUs—The Children’s Hospital of Philadelphia and Cincinnati Children’s Hospital Medical Center. Patients: The study included all patients admitted from July 1, 2014, to June 30, 2015, the year prior to the initiation of any focused situational awareness work at either institution. Interventions: We replicated the predictions of the real-time PICU Warning Tool by retrospectively querying the institutional data warehouse to identify all patients that would have flagged as high-risk by the PICU Warning Tool for their index deterioration. Measurements and Main Results: The primary exposure of interest was determination of high-risk status during PICU admission via the PICU Warning Tool. The primary outcome of interest was clinical deterioration event within 24 hours of a positive screen. The date and time of the deterioration event was used as the index time point. We evaluated the sensitivity, specificity, positive predictive value, and negative predictive value of the performance of the PICU Warning Tool. There were 6,233 patients evaluated with 233 clinical deterioration events experienced by 154 individual patients. The positive predictive value of the PICU Warning Tool was 7.1% with a number needed to screen of 14 patients for each index clinical deterioration event. The most predictive of the individual criteria were elevated lactic acidosis, high mean airway pressure, and profound acidosis. Conclusions: Performance of a clinical decision support translation of a paper-based tool showed inferior test characteristics. Improved feasibility of identification of high-risk patients using automated tools must be balanced with performance. Supplemental digital content is available for this article.

Early Enteral Nutrition Is Associated With Improved Clinical Outcomes in Critically Ill Children: A Secondary Analysis of Nutrition Support in the Heart and Lung Failure-Pediatric Insulin Titration Trial
Objectives: The impact of early enteral nutrition on clinical outcomes in critically ill children has not been adequately described. We hypothesized that early enteral nutrition is associated with improved clinical outcomes in critically ill children. Design: Secondary analysis of the Heart and Lung Failure-Pediatric Insulin Titration randomized controlled trial. Setting: Thirty-five PICUs. Patients: Critically ill children with hyperglycemia requiring inotropic support and/or invasive mechanical ventilation who were enrolled for at least 48 hours with complete nutrition data. Interventions: Subjects received nutrition via guidelines that emphasized enteral nutrition and were classified into early enteral nutrition (enteral nutrition within 48 hr of study randomization) and no early enteral nutrition (enteral nutrition after 48 hr of study randomization, or no enteral nutrition at any time). Measurements and Main Results: Of 608 eligible subjects, 331 (54%) received early enteral nutrition. Both early enteral nutrition and no early enteral nutrition groups had similar daily caloric intake over the first 8 study days (median, 36 vs 36 kcal/kg/d; p = 0.93). After controlling for age, body mass index z scores, primary reason for ICU admission, severity of illness, and mean Vasopressor-Inotrope Score at the time of randomization, and adjusting for site, early enteral nutrition was associated with lower 90-day hospital mortality (8% vs 17%; p = 0.007), more ICU-free days (median, 20 vs 17 d; p = 0.02), more hospital-free days (median, 8 vs 0 d; p = 0.003), more ventilator-free days (median, 21 vs 19 d; p = 0.003), and less organ dysfunction (median maximum Pediatric Logistic Organ Dysfunction, 11 vs 12; p < 0.001). Conclusions: In critically ill children with hyperglycemia requiring inotropic support and/or mechanical ventilation, early enteral nutrition was independently associated with better clinical outcomes.

Extracorporeal Membrane Oxygenation in Pediatric Pulmonary Hypertension
Objective: To describe the epidemiology, critical care interventions, and mortality of children with pulmonary hypertension receiving extracorporeal membrane oxygenation. Design: Retrospective analysis of prospectively collected multicenter data. Setting: Data entered into the Extracorporeal Life Support Organization database between January 2007 and November 2018. Patients: Pediatric patients between 28 days and 18 years old with a diagnosis of pulmonary hypertension. Measurements and Main Results: Six hundred thirty-four extracorporeal membrane oxygenation runs were identified (605 patients). Extracorporeal membrane oxygenation support type was pulmonary (43.1%), cardiac (40.2%), and extracorporeal cardiopulmonary resuscitation (16.7%). The majority of cannulations were venoarterial (80.4%), and 30% had a pre-extracorporeal membrane oxygenation cardiac arrest. Mortality in patients with pulmonary hypertension was 51.3% compared with 44.8% (p = 0.001) in those without pulmonary hypertension. In univariate analyses, significant predictors of mortality included age less than 6 months and greater than 5 years; pre-extracorporeal membrane oxygenation cardiac arrest; pre-extracorporeal membrane oxygenation blood gas with pH less than 7.12, PaCO2 greater than 75, PaO2 less than 35, and arterial oxygen saturation less than 60%; extracorporeal membrane oxygenation duration greater than 280 hours; extracorporeal cardiopulmonary resuscitation; and extracorporeal membrane oxygenation complications including cardiopulmonary resuscitation, inotropic support, myocardial stun, tamponade, pulmonary hemorrhage, intracranial hemorrhage, seizures, other hemorrhage, disseminated intravascular coagulation, renal replacement therapy, mechanical/circuit problem, and metabolic acidosis. A co-diagnosis of pneumonia was associated with significantly lower odds of mortality (odds ratio, 0.5; 95% CI, 0.3–0.8). Prediction models were developed using three sets of variables: 1) pre-extracorporeal membrane oxygenation (age, absence of pneumonia, and pH < 7.12; area under the curve, 0.62); 2) extracorporeal membrane oxygenation related (extracorporeal cardiopulmonary resuscitation, any neurologic complication, pulmonary hemorrhage, renal replacement therapy, and metabolic acidosis; area under the curve, 0.72); and 3) all variables combined (area under the curve, 0.75) (p < 0.001). Conclusions: Children with pulmonary hypertension who require extracorporeal membrane oxygenation support have a significantly greater odds of mortality compared with those without pulmonary hypertension. Risk factors for mortality include age, absence of pneumonia, pre-extracorporeal membrane oxygenation acidosis, extracorporeal cardiopulmonary resuscitation, pulmonary hemorrhage, neurologic complications, renal replacement therapy, and acidosis while on extracorporeal membrane oxygenation. Identification of those pulmonary hypertension patients requiring extracorporeal membrane oxygenation who are at even higher risk for mortality may inform clinical decision-making and improve prognostic awareness.

Research Collaboration in Pediatric Critical Care Randomized Controlled Trials: A Social Network Analysis of Coauthorship
Objectives: Clinical research is a collaborative enterprise; researchers benefit from the expertise, experience, and resources of their collaborators. We sought to describe the extent and patterns of collaboration among pediatric critical care trialists, and to identify the most influential individuals, centers, and countries. Design: Social network analysis of coauthorship. Data Sources: Publications of pediatric critical care randomized controlled trials (1986–2018). Data Extraction: We manually extracted the names of all authors and their affiliations. We used productivity (number of randomized controlled trials), influence (number of citations), and four measures of prominence in the social network (degree, betweenness, closeness, and eigenvector centrality) to identify the most influential individuals. Measurements and Main Results: From 415 randomized controlled trials in pediatric critical care, we identified 2,176 trialists from 377 centers in 43 countries. The coauthorship network is highly disconnected and dominated by a single large cluster of trialists publishing 142 (34%) of the randomized controlled trials. However, 119 (29%) of the randomized controlled trials were published by 28 smaller clusters—a median (interquartile range) of 3 (2–4) randomized controlled trials each. The remaining 154 (37%) randomized controlled trials were coauthored by researchers publishing a single randomized controlled trial each. This overall structure has remained constant with the publication of new randomized controlled trials over 33 years. The most influential trialists and centers varied according to the metric we used; only one trialist and three centers ranked in the top 10 for all measures of influence. Thirty-five of the 40 trialists (88%) ranking in the top 10 of any of the measures were from the United States, the United Kingdom, and Canada. Conclusions: Pediatric critical care has made considerable progress in the number of trialists and randomized controlled trials, but the research enterprise remains highly clustered and fragmented, particularly geographically. Efforts to further increase the quantity and quality of research in the field should include steps to increase the level and range of collaboration.

Intracranial Electroencephalography in Pediatric Severe Traumatic Brain Injury
Objectives: Electroencephalography is used in neurocritical care for detection of seizures and assessment of cortical function. Due to limited resolution from scalp electroencephalography, important abnormalities may not be readily detectable. We aimed to identify whether intracranial electroencephalography allows for improved methods of monitoring cortical function in children with severe traumatic brain injury. Design: This is a retrospective cohort study from a prospectively collected clinical database. We investigated the occurrence rate of epileptiform abnormalities detected on intracranial electroencephalography when compared with scalp electroencephalography. We also investigated the strength of association of quantitative electroencephalographic parameters and cerebral perfusion pressure between both intracranial and scalp electroencephalography. Setting: This is a single-institution study performed in the Phoenix Children’s Hospital PICU. Patients: Eleven children with severe traumatic brain injury requiring invasive neuromonitoring underwent implantation of a six-contact intracranial electrode as well as continuous surface electroencephalography. Interventions: None. Measurements and Main Results: Visual detection of epileptiform abnormalities was performed by pediatric epileptologists. Association of intracranial and scalp electroencephalography total power, alpha percentage, and alpha-delta power ratio to cerebral perfusion pressure was performed using univariate dynamic structural equations modeling. Demographic data were assessed by retrospective analysis. Intracranial and scalp electroencephalography was performed in 11 children. Three of 11 children had observed epileptiform abnormalities on intracranial electroencephalography. Two patients had epileptiform abnormalities identified exclusively on intracranial electroencephalography, and one patient had seizures initiating on intracranial electroencephalography before arising on scalp electroencephalography. Identification of epileptiform abnormalities was associated with subsequent identification of stroke or malignant cerebral edema. We observed statistically significant positive associations between intracranial alpha-delta power ratio to cerebral perfusion pressure in nine of 11 patients with increased strength of association on intracranial compared with scalp recordings. Conclusions: These findings suggest that intracranial electroencephalography may be useful for detection of secondary insult development in children with traumatic brain injury.

Outcomes of Infants Supported With Extracorporeal Membrane Oxygenation Using Centrifugal Versus Roller Pumps: An Analysis From the Extracorporeal Life Support Organization Registry
Objectives: To determine whether mortality differs between roller and centrifugal pumps used during extracorporeal membrane oxygenation in infants weighing less than 10 kg. Design: Retrospective propensity-matched cohort study. Setting: All extracorporeal membrane oxygenation centers reporting to the Extracorporeal Life Support Organization. Patients: All patients less than 10 kg supported on extracorporeal membrane oxygenation during 2011–2016 within Extracorporeal Life Support Organization Registry. Interventions: Centrifugal and roller pump recipients were propensity matched (1:1) based on predicted probability of receiving a centrifugal pump using demographic variables, indication for extracorporeal membrane oxygenation, central versus peripheral cannulation, and pre-extracorporeal membrane oxygenation patient management. Measurements and Main Results: A total of 12,890 patients less than 10 kg were supported with extracorporeal membrane oxygenation within the Extracorporeal Life Support Organization registry during 2011–2016. Patients were propensity matched into a cohort of 8,366. Venoarterial and venovenous extracorporeal membrane oxygenation runs were propensity matched separately. The propensity-matched cohorts were similar except earlier year of extracorporeal membrane oxygenation (standardized mean difference, 0.49) in the roller pump group. Within the propensity-matched cohort, survival to discharge was lower in the centrifugal pump group (57% vs 59%; odds ratio, 0.91; 95% CI, 0.83–0.99; p = 0.04). Hemolytic, infectious, limb injury, mechanical, metabolic, neurologic, pulmonary, and renal complications were more frequent in the centrifugal pump group. Hemorrhagic complications were similar between groups. Hemolysis mediated the relationship between centrifugal pumps and mortality (indirect effect, 0.023; p < 0.001). Conclusions: In this propensity score–matched cohort study of 8,366 extracorporeal membrane oxygenation recipients weighing less than 10 kg, those supported with centrifugal pumps had increased mortality and extracorporeal membrane oxygenation complications. Hemolysis was evaluated as a potential mediator of the relationship between centrifugal pump use and mortality and met criteria for full mediation.

Percutaneous Endoscopic Gastrostomy After Cardiothoracic Surgery in Children Less Than 2 Months Old: An Assessment of Long-Term Malnutrition Status and Gastrostomy Outcomes
Objectives: Infants with critical congenital heart disease undergoing cardiothoracic surgery commonly experience chronic malnutrition and growth failure. We sought to determine whether placement of a percutaneous endoscopic gastrostomy was associated with reduced moderate-severe malnutrition status and to describe percutaneous endoscopic gastrostomy–related clinical and safety outcomes in this population. Design: Single-center, retrospective cohort study. Setting: Two hundred fifty-nine–bed, tertiary care, pediatric referral center. Patients: Children with congenital heart disease less than 2 months old undergoing cardiothoracic surgery from 2007 to 2013 with and without percutaneous endoscopic gastrostomy. Interventions: None. Measurements and Main Results: Primary outcomes were weight for age z scores during hospitalization, at 6 months, and 1 year after cardiothoracic surgery. Secondary outcomes were frequency of percutaneous endoscopic gastrostomy revision, percutaneous endoscopic gastrostomy complications, and mortality. Statistical analyses included Wilcoxon rank-sum, Fisher exact, and Student t tests. Two hundred twenty-two subjects met study criteria, and 77 (35%) had percutaneous endoscopic gastrostomy placed at a mean of 45 ± 31 days after cardiothoracic surgery. No differences were noted for demographics, comorbidities, and weight for age z score at birth and at the time of cardiothoracic surgery. The percutaneous endoscopic gastrostomy cohort had greater Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery risk category (4 [4–5] vs 4 [2–4]) and length of stay (71 d [49–101 d] vs 26 d [15–42 d]). Mean weight for age z score at the time of percutaneous endoscopic gastrostomy was –2.8 ± 1.3. Frequency of moderate-severe malnutrition (weight for age z score, ≤ –2) was greater in children with percutaneous endoscopic gastrostomy at discharge (78% vs 48%), 6 months (61% vs 16%), and 1 year (41% vs 2%). Index mortality was lower in children with percutaneous endoscopic gastrostomy at 30 days (8% vs 0%) and hospital discharge (19% vs 4%). However, no mortality differences were observed after discharge. Growth velocity after percutaneous endoscopic gastrostomy was greater (44 ± 19 vs 10 ± 9 g/d). Children tolerated percutaneous endoscopic gastrostomy without hemodynamic compromise, minor percutaneous endoscopic gastrostomy complications, and anticipated percutaneous endoscopic gastrostomy revisions. Children without mortality had percutaneous endoscopic gastrostomy removal at a median duration of 253 days (133–545 d). Children with univentricular physiology had improved in-hospital mean growth velocity (6.3 vs 24.4 g/d; p < 0.01) and reduced 1-year rate moderate-severe malnutrition (66.7% vs 36.9%; p < 0.01) after percutaneous endoscopic gastrostomy placement. Conclusions: Percutaneous endoscopic gastrostomy placement was well tolerated and associated with improved postoperative growth velocity in children with critical congenital heart disease undergoing cardiothoracic surgery less than 2 months old. These findings were also noted in our subanalysis of children with univentricular physiology. Persistent rates of moderate-severe malnutrition were noted at 1-year follow-up. Although potential index mortality benefit was observed, definitive data are still needed. Supplemental digital content is available for this article.

Delirium in a Tertiary PICU: Risk Factors and Outcomes
Objectives: To determine risk factors and outcomes associated with delirium in PICU patients. Design: Retrospective cohort study. Setting: Thirty-two–bed PICU within a tertiary care academic children’s hospital. Patients: All children admitted to the PICU March 1, 2014, to October 1, 2016, with at least one Cornell Assessment of Pediatric Delirium score (n = 2,446). Interventions: None. Measurements and Main Results: Cornell Assessment of Pediatric Delirium score was performed twice daily as standard of care. We characterized delirium as: 1) presence of greater than or equal to 1 positive score (Cornell Assessment of Pediatric Delirium ≥ 9) and 2) number of days with a positive score. We built multivariable logistic and linear regression models using electronic medical records data. Many patients (n = 1,538; 63%) had a short length of stay (< 48 hr). Compared with patients with length of stay greater than or equal to 48 hours, fewer experienced delirium (30% vs 69%; p < 0.0001). Among 908 patients with length of stay greater than or equal to 48 hours, presence of delirium was independently associated with age less than 2 years old, baseline cognitive dysfunction, primary diagnosis, and duration of mechanical ventilation. Benzodiazepines demonstrated a dose-response effect (odds ratio for presence of delirium, 1.8 [p = 0.03], 3.4 [p < 0.001], and 9.7 [p = 0.005] for < 25th percentile, 25–75th percentile, and > 75th percentile of total dose, vs no exposure). In terms of outcomes, presence of delirium was independently associated with increased ICU length of stay (p < 0.001), whereas days of delirium were independently associated with decline in cognitive function from ICU admission to discharge (odds ratio, 1.06; p < 0.001), increased ICU (p < 0.001), and hospital length of stay (p < 0.001). Neither delirium presence nor total days were independently associated with mortality. Conclusions: Delirium is common in the PICU, particularly among patients with length of stay greater than or equal to 48 hours. It is independently associated with patient characteristics and PICU exposures, including benzodiazepines. The role of delirium as an independent causal factor in patient outcome requires further investigation. Supplemental digital content is available for this article.

Clinical Effects and Outcomes After Polymyxin B–Immobilized Fiber Column Direct Hemoperfusion Treatment for Septic Shock in Preterm Neonates
Objectives: To compare the effectiveness and mortality of early-onset sepsis or late-onset sepsis treatments with polymyxin B–immobilized fiber column direct hemoperfusion in terms of effectiveness and mortality in preterm infants with septic shock. Design: Retrospective cohort study. Setting: Neonatal ICU within a tertiary care hospital. Patients: Of 1,115 patients, 49 had blood culture–proven sepsis between January 2013 and December 2018; six and five patients with septic shock had undergone polymyxin B–immobilized fiber column direct hemoperfusion treatment for early-onset sepsis (early-onset sepsis group) and late-onset sepsis (late-onset sepsis group), respectively. Interventions: None. Measurements and Main Results: Baseline demographic characteristics of both groups were similar. The time from decision to treatment induction was significantly shorter in the early-onset sepsis group than that in the late-onset sepsis group (p = 0.008). The mortality rate after 28 days of treatment and the hospital mortality were significantly lower in the early-onset sepsis group than in the late-onset sepsis group (p = 0.026 and 0.015, respectively). The PaO2/FIO2 ratio was significantly higher in the early-onset sepsis group than in the late-onset sepsis group at the end of the treatment (p = 0.035). In addition, median arterial-to-alveolar oxygen tension ratio significantly improved from 0.19 to 0.55, and median blood pressure also significantly improved from 32.5 to 40.0 mm Hg after the treatment in the early-onset sepsis group. Interleukin-6 levels significantly decreased after treatment in the early-onset sepsis group (p = 0.037). The Pediatric Risk of Mortality III score was similar between the early-onset sepsis and late-onset sepsis groups before and after the treatment. Intraventricular hemorrhage events occurred in both groups, but with no significant differences (p = 0.175). Conclusions: Polymyxin B–immobilized fiber column direct hemoperfusion treatment for preterm infants with septic shock due to early-onset sepsis is associated with earlier hemodynamic and respiratory status improvements and with lower mortality than that due to late-onset sepsis. Early neonatal septic shock detection and polymyxin B–immobilized fiber column direct hemoperfusion induction may improve the prognosis of affected infants. The authors have disclosed that they do not have any potential conflicts of interest.
