Methods Used to Maximize Follow-up: Lessons Learned From the Therapeutic Hypothermia After Pediatric Cardiac Arrest Trials
Objectives: To describe telephone interview completion rates among 12-month cardiac arrest survivors enrolled in the Therapeutic Hypothermia after Pediatric Cardiac Arrest In-Hospital and Out-of-Hospital trials, identify key characteristics of the completed follow-up interviews at both 3- and 12-month postcardiac arrest, and describe strategies implemented to promote follow-up. Setting: Centralized telephone follow-up interviews. Design: Retrospective report of data collected for Therapeutic Hypothermia after Pediatric Cardiac Arrest trials, and summary of strategies used to maximize follow-up completion. Patients: Twelve-month survivors (n = 251) from 39 Therapeutic Hypothermia after Pediatric Cardiac Arrest PICU sites in the United States, Canada, and United Kingdom. Interventions: Not applicable. Measurements and Main Results: The 3- and 12-month telephone interviews included completion of the Vineland Adaptive Behavior Scales, Second Edition. Vineland Adaptive Behavior Scales, Second Edition data were available on 96% of 3-month survivors (242/251) and 95% of 12-month survivors (239/251) with no differences in demographics between those with and without completed Vineland Adaptive Behavior Scales, Second Edition. At 12 months, a substantial minority of interviews were completed with caregivers other than parents (10%), after calls attempts were made on 6 or more days (18%), and during evenings/weekends (17%). Strategies included emphasizing the relationship between study teams and participants, ongoing communication between study team members across sites, promoting site engagement during the study’s final year, and withholding payment for work associated with the primary outcome until work had been completed. Conclusions: It is feasible to use telephone follow-up interviews to successfully collect detailed neurobehavioral outcome about children following pediatric cardiac arrest. Future studies should consider availability of the telephone interviewer to conduct calls at times convenient for families, using a range of respondents, ongoing engagement with site teams, and site payment related to primary outcome completion.

Volume Guaranteed Ventilation During Neonatal Transport
Objectives: To compare tidal volumes, inflating pressures and other ventilator variables of infants receiving synchronized intermitted mandatory ventilation with volume guarantee during emergency neonatal transport with those of infants receiving synchronized intermitted mandatory ventilation without volume guarantee. Design: Retrospective observational study. Setting: A regional neonatal emergency transport service. Patients: We enrolled 77 infants undergoing emergency neonatal transfer. Forty-five infants were ventilated with synchronized intermittent mandatory ventilation with volume guarantee and 32 with synchronized intermitted mandatory ventilation without volume guarantee. Interventions: Infants received synchronized intermitted mandatory ventilation with or without volume guarantee during interhospital emergency neonatal transport using a Fabian + nCPAP evolution neonatal ventilator (Software Version: 4.0.1; Acutronic Medical Instruments, Hirzel, Switzerland). Measurements and Main Results: We downloaded detailed ventilator data with 0.5 Hz sampling rate. We analyzed data with the Python computer language and its data science packages. The mean expiratory tidal volume of inflations was lower and less variable in infants ventilated with volume guarantee than in babies ventilated without volume guarantee (group median 4.8 vs 6.0 mL/kg; p = 0.001). Babies ventilated with synchronized intermittent mandatory ventilation with volume guarantee had on average lower and more variable peak inflating pressures than babies ventilated without volume guarantee (group median 15.5 vs 19.5 cm H2O;p = 0.0004). With volume guarantee, a lower proportion of the total minute ventilation was attributed to ventilator inflations rather than to spontaneous breaths between inflations (group median 66% vs 83%; p = 0.02). With volume guarantee, babies had fewer inflations with tidal volumes greater than 6 mL/kg and greater than 8 mL/kg (group medians 3% vs 44% and 0% vs 7%, respectively; p = 0.0001). The larger tidal volumes in the non-volume guarantee group were not associated with significant hypocapnia except in one case. Conclusions: During neonatal transport, synchronized intermittent mandatory ventilation with volume guarantee ventilation reduced the occurrence of excessive tidal volumes, but it was associated with larger contribution of spontaneous breaths to minute ventilation compared with synchronized intermitted mandatory ventilation without volume guarantee.

Survival and Cardiopulmonary Resuscitation Hemodynamics Following Cardiac Arrest in Children With Surgical Compared to Medical Heart Disease
Objectives: To assess the association of diastolic blood pressure cutoffs (≥ 25 mm Hg in infants and ≥ 30 mm Hg in children) during cardiopulmonary resuscitation with return of spontaneous circulation and survival in surgical cardiac versus medical cardiac patients. Secondarily, we assessed whether these diastolic blood pressure targets were feasible to achieve and associated with outcome in physiology unique to congenital heart disease (single ventricle infants, open chest), and influenced outcomes when extracorporeal cardiopulmonary resuscitation was deployed. Design: Multicenter, prospective, observational cohort analysis. Setting: Tertiary PICU and cardiac ICUs within the Collaborative Pediatric Critical Care Research Network. Patients: Patients with invasive arterial catheters during cardiopulmonary resuscitation and surgical cardiac or medical cardiac illness category. Interventions: None. Measurements and Main Results: Hemodynamic waveforms during cardiopulmonary resuscitation were analyzed on 113 patients, 88 surgical cardiac and 25 medical cardiac. A similar percent of surgical cardiac (51/88; 58%) and medical cardiac (17/25; 68%) patients reached the diastolic blood pressure targets (p = 0.488). Achievement of diastolic blood pressure target was associated with improved survival to hospital discharge in surgical cardiac patients (p = 0.018), but not medical cardiac patients (p = 0.359). Fifty-three percent (16/30) of patients with single ventricles attained the target diastolic blood pressure. In patients with an open chest at the start of chest compressions, 11 of 20 (55%) attained the target diastolic blood pressure. In the 33 extracorporeal cardiopulmonary resuscitation patients, 16 patients (48%) met the diastolic blood pressure target with no difference between survivors and nonsurvivors (p = 0.296). Conclusions: During resuscitation in an ICU, with invasive monitoring in place, diastolic blood pressure targets of greater than or equal to 25 mm Hg in infants and greater than or equal to 30 mm Hg in children can be achieved in patients with both surgical and medical heart disease. Achievement of diastolic blood pressure target was associated with improved survival to hospital discharge in surgical cardiac patients, but not medical cardiac patients. Diastolic blood pressure targets were feasible to achieve in 1) single ventricle patients, 2) open chest physiology, and 3) extracorporeal cardiopulmonary resuscitation patients.

Effects of Healthcare-Associated Infections on Length of PICU Stay and Mortality
Objectives: To identify the effects of healthcare-associated infections on length of PICU stay and mortality. Design: Retrospective, single-center, observational study. Setting: PICU of a tertiary children’s hospital. Patients: Consecutive patients who stayed greater than 48 hours in the PICU between January 2013 and December 2017. Interventions: None. Measurements and Main Results: Data were retrospectively collected from medical records. We identified occurrences of common healthcare-associated infections, including bloodstream infection, pneumonia, and urinary tract infection, defined according to the 2008 definitions of the Centers for Disease Control and Prevention and National Healthcare Safety Network. We assessed the effects of each healthcare-associated infection on length of PICU stay and PICU mortality using multivariable analysis. Among 1,622 admissions with a PICU stay greater than 48 hours, the median age was 299 days and male patients comprised 51% of admissions. The primary diagnostic categories were cardiovascular (58% of admissions), respiratory (21%), gastrointestinal (8%), and neurologic/muscular (6%). The median length of PICU stay was 6 days, and the PICU mortality rate was 2.5%. A total of 167 healthcare-associated infections were identified, including 67 bloodstream infections (40%), 43 pneumonias (26%), and 57 urinary tract infections (34%). There were 152 admissions with at least one healthcare-associated infection (9.4% of admissions with a stay > 48 hr). On multivariable analysis, although each healthcare-associated infection was not significantly associated with mortality, bloodstream infection was associated with an extra length of PICU stay of 10.2 days (95% CI, 7.9–12.6 d), pneumonia 14.2 days (11.3–17.2 d), and urinary tract infection 6.5 days (4.0–9.0 d). Accordingly, 9.7% of patient-days were due to these three healthcare-associated infections among patients with a stay greater than 48 hours. Conclusions: Although healthcare-associated infections were not associated with PICU mortality, they were associated with extra length of PICU stay. As 9.7% of patient-days were due to healthcare-associated infections, robust prevention efforts are warranted. The authors have disclosed that they do not have any potential conflicts of interest.

Hospital-Acquired Pressure Injuries in Children With Congenital Heart Disease: Prevalence and Associated Factors
Objectives: To explore the prevalence, location, and clinical factors associated with hospital-acquired pressure injuries among pediatric patients with congenital heart disease. Design: Secondary analysis of data from a multicenter prospective cohort study of pediatric pressure injury risk, including patients with congenital heart disease. Setting: Eight acute care academic pediatric hospitals. Patients: Patients were preterm to 21 years old with congenital heart disease and on bed rest for at least 24 hours after hospital admission with a medical device attached to or traversing the skin or mucous membrane. Interventions: None. Measurements and Main Results: Patients were evaluated for a maximum of eight observations during a 4-week period to identify Braden QD risk and pressure injury development. Hospital-acquired pressure injuries were staged according to the National Pressure Ulcer Advisory Panel guidelines. Stepwise logistic regression was used to explore risk factors associated with hospital-acquired pressure injuries development, accounting for site as a cluster variable using generalized estimating equations. Overall, 279 pediatric cardiac patients provided 919 observations (median, 2 per patient [interquartile range, 2–5 per patient]). Thirty-eight hospital-acquired pressure injuries occurred in 27 patients (9.7%). Most injuries (28/38 [74%]) were related to medical devices. The most common medical devices that caused injury were oxygen saturation probes. The remaining hospital-acquired pressure injuries were immobility-related pressure injuries (10/38 [26%]) located primarily on the buttock, sacrum, or coccyx (5/10 [50%]). In multivariable analyses, being non-Hispanic white (odds ratio, 3.54; 95% CI, 2.15–5.84), experiencing operating room time greater than 4 hours (odds ratio, 2.91; 95% CI, 1.13–7.49), having oxygen saturation levels less than 85% (odds ratio, 2.65; 95% CI, 1.01–6.96), and having worse Braden QD scores (odds ratio, 1.25 per 1 point increase; 95% CI, 1.17–1.34) were significantly associated with hospital-acquired pressure injuries development. Conclusions: In this multicenter observational study of pediatric patients with congenital heart disease, we describe a hospital-acquired pressure injury prevalence of 9.7% with approximately 75% of injuries related to medical devices. These data can be used to inform practice and target interventions to decrease pressure injury risk and prevent pressure injuries in this vulnerable pediatric population.

Polyneuropathy in Critically Ill Mechanically Ventilated Children: Experience From a Tertiary Care Hospital in North India
Objectives: To determine the prevalence of critical illness polyneuropathy and its risk factors in critically ill children mechanically ventilated for 7 days or more. Design: Observational cohort study. Setting: PICU of a tertiary care hospital from North India. Patients: Children 1–15 years old admitted in PICU from June 2016 to September 2017, mechanically ventilated for 7 days or more, excluding those with diagnosed neuromuscular disease, stroke, or spinal pathology. Intervention: Demographic details, diagnosis, treatment details, and anthropometry at admission and enrolment were recorded. Nerve conduction studies were performed after enrolment and repeated a week later, if the child was still in PICU. Medical Research Council scoring for muscle strength was performed in survivors. Risk factors including Pediatric Index of Mortality-2 score, sepsis, multiple organ dysfunction, hypoalbuminemia, use of steroids, neuromuscular-blocking agents, and vasopressors were recorded. Samples for the level of micronutrients (copper, zinc, folate, and vitamin B12) were collected at the time of enrolling the child and at the time of discharge. Measurements and Main Results: Thirty-two children were enrolled, of whom 29 had features of critical illness polyneuropathy on evaluation at day 8 of mechanical ventilation (prevalence, 90.6% [95% CI, 80.5–100%]). The polyneuropathy was axonal in 26 (81.2%), mixed in one patient (3.1%), and uncharacterized in two (6.2%). Sepsis and multiple organ dysfunction were present in 31 subjects (96.9%). No risk factors for critical illness polyneuropathy could be identified although the study was not sufficiently powered to do so. The difference between serum micronutrient levels (copper, zinc, folate, and vitamin B12) between patients who developed polyneuropathy, and those who did not, was statistically insignificant. Conclusions: We observed a high prevalence of critical illness polyneuropathy in children in PICU, mechanically ventilated for 7 days or more; almost all of whom had underlying sepsis. This work was conducted at the All India Institute of Medical Science, New Delhi, India.

Bioactive Oxylipins in Infants and Children With Congenital Heart Disease Undergoing Pediatric Cardiopulmonary Bypass
Objectives: To determine the production of 9-hydroxyoctadecadienoic acid and 13-hydroxyoctadecadienoic acid during cardiopulmonary bypass in infants and children undergoing cardiac surgery, evaluate their relationship with increase in cell-free plasma hemoglobin, provide evidence of bioactivity through markers of inflammation and vasoactivity (WBC count, milrinone use, vasoactive-inotropic score), and examine their association with overall clinical burden (ICU/hospital length of stay and mechanical ventilation duration). Design: Prospective observational study. Setting: Twelve-bed cardiac ICU in a university-affiliated children’s hospital. Patients: Children were prospectively enrolled during their preoperative clinic appointments with the following criteria: greater than 1 month to less than 18 years old, procedures requiring cardiopulmonary bypass Interventions: None. Measurements and Main Results: Plasma was collected at the start and end of cardiopulmonary bypass in 34 patients. 9-hydroxyoctadecadienoic acid, 13-hydroxyoctadecadienoic acid, plasma hemoglobin, and WBC increased. 9:13-hydroxyoctadecadienoic acid at the start of cardiopulmonary bypass was associated with vasoactive-inotropic score at 2–24 hours postcardiopulmonary bypass (R2 = 0.25; p < 0.01), milrinone use (R2 = 0.17; p < 0.05), and WBC (R2 = 0.12; p < 0.05). 9:13-hydroxyoctadecadienoic acid at the end of cardiopulmonary bypass was associated with vasoactive-inotropic score at 2–24 hours (R2 = 0.17; p < 0.05), 24–48 hours postcardiopulmonary bypass (R2 = 0.12; p < 0.05), and milrinone use (R2 = 0.19; p < 0.05). 9:13-hydroxyoctadecadienoic acid at the start and end of cardiopulmonary bypass were associated with the changes in plasma hemoglobin (R2 = 0.21 and R2 = 0.23; p < 0.01). The changes in plasma hemoglobin was associated with milrinone use (R2 = 0.36; p < 0.001) and vasoactive-inotropic score less than 2 hours (R2 = 0.22; p < 0.01), 2–24 hours (R2 = 0.24; p < 0.01), and 24–48 hours (R2 = 0.48; p < 0.001) postcardiopulmonary bypass. Cardiopulmonary bypass duration, 9:13-hydroxyoctadecadienoic acid at start of cardiopulmonary bypass, and plasma hemoglobin may be risk factors for high vasoactive-inotropic score. Cardiopulmonary bypass duration, changes in plasma hemoglobin, 9:13-hydroxyoctadecadienoic acid, and vasoactive-inotropic score correlate with ICU and hospital length of stay and/mechanical ventilation days. Conclusions: In low-risk pediatric patients undergoing cardiopulmonary bypass, 9:13-hydroxyoctadecadienoic acid was associated with changes in plasma hemoglobin, vasoactive-inotropic score, and WBC count, and may be a risk factor for high vasoactive-inotropic score, indicating possible inflammatory and vasoactive effects. Further studies are warranted to delineate the role of hydroxyoctadecadienoic acids and plasma hemoglobin in cardiopulmonary bypass-related dysfunction and to explore hydroxyoctadecadienoic acid production as a potential therapeutic target.

Evaluation of Pediatric Cardiac ICU Advanced Practice Provider Education and Practice Variation
Objectives: The education, training, and scope of practice of cardiac ICU advanced practice providers is highly variable. A survey was administered to cardiac ICU advanced practice providers to examine specific variations in orientation format, competency assessment during and at the end of orientation, and scope of clinical practice to determine gaps in resources and need for standardization. Design: This study was a cross-sectional descriptive study utilizing survey responses. Setting: Pediatric cardiac ICUs in the United States. Subjects: The survey was delivered to a convenience sample of advanced practice providers currently practicing in pediatric cardiac ICUs. Interventions: A list of pediatric cardiothoracic surgery programs was generated from the Society of Thoracic Surgery database. A self-administered, electronic survey was delivered via email to advanced practice providers at those institutions. Descriptive data were compared using a chi-square test or Fisher exact test depending on the normalcy of data. Continuous data were compared using a Student t test or Mann-Whitney U test. Measurements and Main Results: Eighty-three of 157 advanced practice providers responded (53% response rate, representing 36 institutions [35% of institutions]). Sixty-five percent of respondents started as new graduates. Ninety-three to one-hundred percent obtain a history and physical, order/interpret laboratory, develop management plans, order/titrate medications, and respiratory support. Ability to perform invasive procedures was highly variable but more likely for those in a dedicated cardiac ICU. Seventy-seven percent were oriented by another advanced practice provider, with a duration of orientation less than 4 months (66%). Fifty percent of advanced practice providers had no guidelines in place to guide learning/competency during orientation. Sixty-seven percent were not evaluated in any way on their knowledge or skills during or at the end of orientation. Orientation was rated as poor/fair by the majority of respondents for electrophysiology (58%) and echocardiography (69%). Seventy-one percent rated orientation as moderately effective or less. Respondents stated they would benefit from more structured didactic education with clear objectives, standardized management guidelines, and more simulation/procedural practice. Eighty-five percent were very/extremely supportive of a standardized cardiac ICU advanced practice provider curriculum. Conclusions: Orientation for cardiac ICU advanced practice providers is highly variable, content depends on the institution/preceptor, and competency is not objectively defined or measured. A cardiac ICU advanced practice provider curriculum is needed to standardize education and promote the highest level of advanced practice provider practice.

Extracorporeal Membrane Oxygenation for Severe Adenoviral Pneumonia in Neonatal, Pediatric, and Adult Patients
Objectives: We examined data on patients with severe adenoviral pneumonia from the international registry of the Extracorporeal Life Support Organization to identify risk factors for mortality in patients receiving extracorporeal membrane oxygenation. Design: Retrospective analysis. Setting: International Registry of Extracorporeal Life Support Organization. Patients: We collected de-identified data on all patients with adenoviral pneumonia who needed extracorporeal membrane oxygenation from 1992 to 2016 using International Classification of Diseases, 9th Edition, criteria. Interventions: Our primary outcome measure was in-hospital mortality. We also collected data on demographics, preextracorporeal membrane oxygenation ventilator settings, biochemical variables, extracorporeal membrane oxygenation mode, duration, and complications. Initial bivariate analysis assessed potential associations between mortality and various preextracorporeal membrane oxygenation variables as well as extracorporeal membrane oxygenation factors. Variables with p values of less than 0.1 were considered for logistic regression analysis that identified predictors of mortality. Measurements and Results: There were 542 patients with adenoviral pneumonia who were supported with extracorporeal membrane oxygenation. Overall mortality was 58% (307/529 patients) (neonates 86.4% [108/125 patients], children 49% [158/327 patients], and adults 49% [41/83 patients]). Multivariate regression identified hypercapnia (PCO2 > 45.7; odds ratio > 3.2; p < 0.001), immunosuppression (odds ratio, 4.44; 95% CI, 1.69–11.61; p = 0.002] and lack of pharmacologic paralysis (odds ratio, 0.30; 95% CI, 0.16–0.57; p < 0.001] as significant preextracorporeal membrane oxygenation factors for mortality. Neonatal patients had significantly higher mortality than pediatric or adult patients (odds ratio, 10.9; 95% CI, 3.2–37.3; p < 0.001). The presence of renal (odds ratio, 4.4; 95% CI, 2.5–7.7; p < 0.001), neurologic (odds ratio, 2.5; 95% CI, 1.2–5.1; p = 0.014), hemorrhagic (odds ratio, 2.2; 95% CI, 1.2–4.0; p = 0.014), or cardiovascular complications (odds ratio, 2.4; 95% CI, 1.3–4.6; p = 0.006) was associated with higher mortality on extracorporeal membrane oxygenation. Conclusions: Patients with adenoviral pneumonia supported on extracorporeal membrane oxygenation had mortality of 58% over a 25-year-old period. We identified risk factors both before and during extracorporeal membrane oxygenation which were associated with higher mortality. Mortality in neonatal patients was particularly high.
