In-Hospital Cardiac Arrest in Adult Patients Admitted to a Quaternary Children's Center.

OBJECTIVE: This study aimed to describe baseline and event characteristics and outcomes for adult patients who experience in-hospital cardiac arrest (IHCA) in a quaternary children's hospital and compare IHCA outcomes in younger (18-24 years) versus older (≥25 years) adults. We hypothesized that the rate of survival to hospital discharge would be lower in the older adult group. METHODS: We performed a retrospective single-center cohort study of inpatient areas of a quaternary children's center. Adult patients (≥18 years of age) with an index pulseless IHCA requiring at least 1 minute of cardiopulmonary resuscitation or defibrillation were included. RESULTS: Thirty-three events met the inclusion criteria with a median patient age of 23.9 years (interquartile range, 20.2-33.3 years). Twenty-one (64%) patients had congenital heart disease, and 25 (76%) patients had comorbidities involving ≥2 organ systems. The most common prearrest interventions were invasive mechanical ventilation (76%) and vasoactive infusions (55%). Seventeen patients (52%) survived to hospital discharge.Survival to discharge was lower in patients 25 years or older compared with patients aged 18 to 24 years old (3 of 15 [20%] vs 14 of 18 [78%], respectively; P = 0.002). CONCLUSIONS: The majority of adult patients with IHCA in our pediatric hospital had preexisting multisystem comorbidities, the most common of which was congenital heart disease. Overall survival to discharge after IHCA was 52%, similar to that reported for the general pediatric population. Survival to discharge was significantly lower in the subgroup of patients 25 years or older when compared with those between the ages of 18 and 24 years.

Association Between Anticholinergic Drug Burden and Adequacy of Enteral Nutrition in Critically Ill, Mechanically Ventilated Pediatric Patients.

OBJECTIVES: Enteral nutrition delivery is limited by intolerance and interruptions in critically ill children. Anticholinergic properties of frequently administered medications may contribute to altered gastric motility and enteral nutrition intolerance in this population. We examined the association between the anticholinergic burden of administered medications using the Anticholinergic Drug Scale and adequacy of enteral nutrition delivery. DESIGN: Secondary analysis of data from a previously characterized PICU cohort. SETTING: Multidisciplinary PICU in a quaternary academic medical center. PATIENTS: Younger than or equal to 18 years, on mechanical ventilation and received enteral nutrition within the first 3 days of PICU admission. MEASUREMENTS AND MAIN RESULTS: Daily Anticholinergic Drug Scale score, demographic data, and clinical data were obtained from the primary study. Percent enteral energy adequacy ([kcal delivered ÷ kcal prescribed] × 100) during the first 3 days of PICU admission was calculated. Forty-two patients received enteral nutrition, with median age (interquartile range) 5 years (1.09-12.54 yr), and 62% were male. Median Anticholinergic Drug Scale score was inversely correlated with energy adequacy, with a median 9% decline in energy adequacy per 1-point increase in Anticholinergic Drug Scale score (coefficient, -9.3; 95% CI, -13.43 to -5.27; R2 = 0.35; p < 0.0001). Median hours of enteral nutrition interruptions directly correlated with Anticholinergic Drug Scale score (coefficient, 1.5; 95% CI, 0.531-2.54; R2 = 0.19; p = 0.004). Severity score was greater in patients with less than or equal to 25% enteral energy adequacy and directly correlated with median Anticholinergic Drug Scale score. CONCLUSIONS: Anticholinergic burden from medications administered in the PICU is a potentially modifiable factor for suboptimal enteral nutrition delivery.

Current State of Nutrition Education in Pediatric Critical Care Medicine Fellowship Programs in the United States and Canada.

OBJECTIVES: To assess the current state of nutrition education provided during pediatric critical care medicine fellowship. DESIGN: Cross-sectional survey. SETTING: Program directors and fellows from pediatric critical care medicine fellowship programs in America and Canada. SUBJECTS: Seventy current pediatric critical care medicine fellows and twenty-five pediatric critical care medicine fellowship program directors were invited to participate. INTERVENTIONS: Participants were asked demographic questions related to their fellowship programs, currently utilized teaching methods, perceptions regarding adequacy and effectiveness of current nutrition education, and levels of fellow independence, comfort, confidence, and expectations in caring for the nutritional needs of patients. MEASUREMENTS AND MAIN RESULTS: Surveys were sent to randomly selected program directors and fellows enrolled in pediatric critical care medicine fellowship programs in America and Canada. Twenty program directors (80%) and 60 fellows (86%) responded. Ninety-five percent of programs (19/20) delivered a formal nutrition curriculum; no curriculum was longer than 5 hours per academic year. Self-reported fellow comfort with nutrition topics did not improve over the course of fellowship (p = 0.03), with the exception of nutritional aspects of special diets. Sixty-five percent of programs did not hold fellows responsible for writing daily parenteral nutrition prescriptions. There was an inverse relationship between total number of fellows in a pediatric critical care medicine program and levels of comfort in ability to provide parenteral nutrition support (p = 0.01). Program directors perceived their nutritional curriculum to be more effective than did their fellows (p ≤ 0.001). CONCLUSIONS: Nutrition education was reported as highly underrepresented in pediatric critical care medicine fellowship curricula. The majority of programs rely on allied health care professionals to prescribe parenteral nutrition, which may influence trainee independence in the provision of nutritional therapies. Improving the format of current nutrition curriculums, by relying on more active teaching methods, may improve the delivery and efficacy of nutrition education. The impact of novel training interventions on improving the competency and safety of enteral and parenteral nutrition delivery in the PICU must be further examined.

Postpyloric vs gastric enteral nutrition in critically ill children: A single-center retrospective cohort study.

BACKGROUND: We aimed to describe enteral nutrition (EN) delivery in patients receiving postpyloric EN (PPEN) vs gastric EN (GEN). METHODS: Single-center retrospective study including patients aged <21 years admitted to an intensive care unit in a pediatric quaternary care hospital for ≧48 h who received PPEN or GEN as a first approach, as guided by a nutrition algorithm. PPEN patients were 1:1 propensity score matched to GEN patients on demographics, clinical characteristics, and disease severity. Days to EN initiation from admission, percentage of EN adequacy (delivered EN volume/prescribed EN volume) on days 1-3 and 7 after EN initiation, and time to achieving 60% of prescribed EN volume were compared between the two groups using Wilcoxon Mann-Whitney tests and a Cox proportional hazards model. Data are presented as median (IQR1, IQR3). RESULTS: Forty-six PPEN and 46 GEN patients were matched. Median time to EN initiation was 3.25 (2, 6.8) days for PPEN and 4.15 (1.5, 7.1) days for GEN (P = 0.6). Percentage of EN adequacy was greater for PPEN than GEN patients (day 1 PPEN 59.4% [18.8, 87.5] vs GEN 21.1% [7.8, 62.8], day 2 PPEN 54.3% [16.7, 95.8] vs GEN 24% [5.4, 56.7], day 3 PPEN 65.4% [14.7, 100] vs GEN 16% [0, 64.6], day 7 PPEN 77.8% [11.1, 100] vs GEN 13.8% [0, 74.5]; P < 0.05). PPEN patients had greater likelihood of achieving 60% of their prescribed EN volume than GEN patients (hazard ratio 1.84, 95% CI 1.07-3.15; P = 0.028). CONCLUSION: PPEN was associated with greater EN delivery compared with GEN.

Impact of implementing an evidence-based definition of enteral nutrition intolerance on nutrition delivery: A prospective, cross-sectional cohort study.

BACKGROUND: Enteral nutrition (EN) interruptions because of EN intolerance impede nutrient delivery. We aimed to examine whether revising the EN intolerance definition of an algorithm would decrease EN interruptions and improve nutrient delivery in critically ill children. METHODS: We performed a cross-sectional cohort study including patients who were admitted to our intensive care unit (ICU) for >24 h and received EN. The EN intolerance definition in our nutrition algorithm was modified to include two symptoms of EN intolerance. We compared time to 60% EN adequacy (EN delivered/EN prescribed x 100) and EN interruptions before and after this intervention. RESULTS: We included 150 eligible patients, 78 and 72 patients in the preimplementation and postimplementation cohorts, respectively. There were no significant differences in demographics and clinical characteristics. The preimplementation and postimplementation cohorts achieved 60% EN adequacy 4 (2-5) days and 3 (2-5) days after ICU admission, respectively (P = 0.59). The preimplementation cohort had a median of 1 (1-2) interruption per patient and the postimplementation cohort 2 (1-3; P = 0.08). The frequency of interruptions because of EN intolerance within the first 8 days of ICU admission was 17 in the preimplementation and 10 in the postimplementation cohorts. CONCLUSION: Modifying the EN intolerance definition of a nutrition algorithm did not change the time to 60% EN adequacy or total number of EN interruptions in critically ill children. EN intolerance and interruptions continue to limit nutrient delivery. Research on the best definition for EN intolerance and its effect on nutrition outcomes is needed.

Exposure to Anticholinergic Medications in Pediatric Severe Sepsis and Feasibility of Delirium Screening.

In sepsis, anticholinergic dysregulation may result in encephalopathy or delirium during severe illness, either as a result of central inflammation or because of exposure to medications with anticholinergic activity. In this retrospective study, we determined the magnitude of anticholinergic drug exposure in 75 children with severe sepsis. We found that exposure over the first 5 days was high-median (interquartile range) daily anticholinergic drug scale score 4 (2-5)-and associated with higher vasoactive scores and death. We conclude that anticholinergic drug exposure is significant in severe sepsis, which means it may be a modifiable factor that should be studied further.

Bedside Postpyloric Tube Placement and Enteral Nutrition Delivery in the Pediatric Intensive Care Unit.

BACKGROUND: Enteral nutrition (EN) delivery may be more effective via a postpyloric (PP) feeding tube in critically ill children, but tube placement can be challenging. We aimed to describe PP tube placement and EN practices in a multidisciplinary pediatric intensive care unit (PICU) after the implementation of a nurse-led bedside PP tube-placement program. METHODS: In a single-center retrospective study, we identified 100 consecutive patients admitted to the PICU for >48 hours and for whom PP tube placement was attempted. Demographics, clinical characteristics, and details of PP tube placement and EN delivery were examined. RESULTS: The study cohort had a median age (25th, 75th percentiles) of 3.89 years (0.55, 14.86); 66% were male. Respiratory illness was the primary diagnosis of admission (55%); 92% were on respiratory support. Risk of aspiration was the primary indication for PP tube placement (48%). Bedside placement was the initial technique for PP tube placement in 93% of patients (successful for 84.9%) and was not associated with serious complications. Eighty-seven patients with a PP tube started EN and received a median 73.9% (12.3%, 100%) of prescribed energy goal on day 3 after EN initiation. PP EN allowed 14 of 39 patients receiving parenteral nutrition (PN) to transition off PN 7 days after EN initiation. Thirty-five percent of EN interruptions were due to feeding-tube dysfunction. CONCLUSION: Bedside PP tube placement is safe and feasible and allows for effective EN delivery and decreased PN use when applicable. Interruptions in PP EN due to tube malfunction are prevalent.
