RESUMEN

OBJECTIVES: Pediatric Advanced Life Support (PALS) guidelines include weight-based epinephrine dosing recommendations of 0.01 mg/kg with a maximum of 1 mg, which corresponds to a weight of 100 kg. Actual practice patterns are unknown. DESIGN: Multicenter cross-sectional survey regarding institutional practices for the transition from weight-based to flat dosing of epinephrine during cardiopulmonary resuscitation in PICUs. Exploratory analyses compared epinephrine dosing practices with several institutional characteristics using Fisher exact test. SETTING: Internet-based survey. SUBJECTS: U.S. PICU representatives (one per institution) involved in resuscitation systems of care. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 137 institutions surveyed, 68 (50%) responded. Most responding institutions are freestanding children's hospitals or dedicated children's hospitals within combined adult/pediatric hospitals (67; 99%); 55 (81%) are academic and 41 (60%) have PICU fellowship programs. Among respondents, institutional roles include PICU medical director (13; 19%), resuscitation committee member (23; 34%), and attending physician with interest in resuscitation (21; 31%). When choosing between weight-based and flat dosing, 64 respondents (94%) report using patient weight, 23 (34%) patient age, and five (7%) patient pubertal stage. Among those reporting using weight, 28 (44%) switch at 50 to less than 60 kg, 17 (27%) at 60 to less than 80 kg, five (8%) at 80 to less than 100 kg, and eight (12%) at greater than or equal to 100 kg. Among those reporting using age, four (17%) switch at 14 to less than 16 years, five (22%) at 16 to less than 18, and six (26%) at greater than or equal to 18. Twenty-nine respondents (43%) report using ideal body weight when dosing epinephrine in obese patients. Using patient age in choosing epinephrine dosing is more common in institutions that require Advanced Cardiac Life Support (ACLS) certification for some/all code team responders compared with institutions that do not require ACLS certification (52% vs 22%; p = 0.02). CONCLUSIONS: The majority of PICUs surveyed report epinephrine dosing practices that are inconsistent with PALS guidelines.

RESUMEN

OBJECTIVES: The Heart And Lung Failure-Pediatric INsulin Titration study was experiencing poor subject enrollment due to low rates of informed consent. Heart And Lung Failure-Pediatric INsulin Titration investigators collaborated with the Perelman School of Medicine Standardized Patient Program to explore the novel use of telesimulation with standardized parents to train research staff to approach parents of critically ill children for informed consent. We describe the feasibility, learner acceptance, and financial costs of this novel intervention and performed a post hoc analysis to determine if this intervention improved study consent rates. DESIGN: Observational, comparative effectiveness study. SETTING: Heart And Lung Failure-Pediatric INsulin Titration study enrolling sites. SUBJECTS: Research staff (at the remote site). INTERVENTIONS: Individual 90-minute Skype telesimulation sessions with standardized parent and simulation facilitator (at the training site). MEASUREMENTS AND MAIN RESULTS: Forty telesimulation sessions with 79 Heart And Lung Failure-Pediatric INsulin Titration research staff (participants) at 24 remote sites were conducted. Despite some technical delays, 40 out of 40 simulations (100%) were completed. Based on feedback surveys, 100% of respondents agreed (81% strongly agreed) that telesimulation sessions achieved intended learning objectives to prepare research staff to approach parents of eligible critically ill children to obtain informed consent. Additionally, 100% of respondents agreed (74% strongly agreed) that they would use lessons from the telesimulation when approaching parents to obtain informed consent for research. Telesimulation with standardized parents achieved lower financial costs (approximately $85 per session) compared with traditional in-person site visits for training research staff. There was no significant improvement in study consent rates with the intervention (pre: 46% vs post: 48%; p = 0.78). CONCLUSIONS: Remote telesimulation with standardized parents is feasible, acceptable, and associated with lower financial costs to prepare research staff to obtain informed consent from parents of critically ill children eligible for clinical research trials. Despite this novel approach, Heart And Lung Failure-Pediatric INsulin Titration study consent rates did not improve, suggesting that other factors influence parental consent and decision making in complex multicenter clinical research trials.

RESUMEN

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.

RESUMEN

OBJECTIVES: The impact of nutrition status on outcomes in pediatric severe sepsis is unclear. We studied the association of nutrition status (expressed as body mass index z score) with outcomes in pediatric severe sepsis. DESIGN: Secondary analysis of the Sepsis Prevalence, Outcomes, and Therapies study. Patient characteristics, ICU interventions, and outcomes were compared across nutrition status categories (expressed as age- and sex-adjusted body mass index z scores using World Health Organization standards). Multivariable regression models were developed to determine adjusted differences in all-cause ICU mortality and ICU length of stay by nutrition status. SETTING: One-hundred twenty-eight PICUs across 26 countries. PATIENTS: Children less than 18 years with severe sepsis enrolled in the Sepsis Prevalence, Outcomes, and Therapies study (n = 567). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Nutrition status data were available for 417 patients. Severe undernutrition was seen in Europe (25%), Asia (20%), South Africa (17%), and South America (10%), with severe overnutrition seen in Australia/New Zealand (17%) and North America (14%). Severe undernutrition was independently associated with all-cause ICU mortality (adjusted odds ratio, 3.0; 95% CI, 1.2-7.7; p = 0.02), whereas severe overnutrition in survivors was independently associated with longer ICU length of stay (1.6 d; p = 0.01). CONCLUSIONS: There is considerable variation in nutrition status for children with severe sepsis treated across this selected network of PICUs from different geographic regions. Severe undernutrition was independently associated with higher all-cause ICU mortality in children with severe sepsis. Severe overnutrition was independently associated with greater ICU length of stay in childhood survivors of severe sepsis.

RESUMEN

OBJECTIVES: The 2012 Surviving Sepsis Campaign pediatric guidelines recommend stress dose hydrocortisone in children experiencing catecholamine-dependent septic shock with suspected or proven absolute adrenal insufficiency. We evaluated whether stress dose hydrocortisone therapy in children with catecholamine dependent septic shock correlated with random serum total cortisol levels and was associated with improved outcomes. DESIGN: Retrospective cohort study. SETTING: Non-cardiac PICU. PATIENTS: Critically ill children (1 mo to 18 yr) admitted between January 1, 2013, and December 31, 2013, with catecholamine dependent septic shock who had random serum total cortisol levels measured prior to potential stress dose hydrocortisone therapy. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The cohort was dichotomized to random serum total cortisol less than 18 mcg/dL and greater than or equal to 18 mcg/dL. Associations of stress dose hydrocortisone with outcomes: PICU mortality, PICU and hospital length of stay, ventilator-free days, and vasopressor-free days were examined. Seventy children with catecholamine-dependent septic shock and measured random serum total cortisol levels were eligible (16% PICU mortality). Although 43% (30/70) had random serum total cortisol less than 18 µg/dL, 60% (42/70) received stress dose hydrocortisone. Children with random serum total cortisol less than 18 µg/dL had lower severity of illness and lower Vasopressor Inotrope Scores than those with random serum total cortisol greater than or equal to 18 µg/dL (all p < 0.05). Children with stress dose hydrocortisone had higher severity of illness and PICU mortality than those without stress dose hydrocortisone (all p < 0.05). Mean random serum total cortisol levels were similar in children with and without stress dose hydrocortisone (21.1 vs 18.7 µg/dL; p = 0.69). In children with random serum total cortisol less than 18 µg/dL, stress dose hydrocortisone was associated with greater PICU and hospital length of stay and fewer ventilator-free days (all p < 0.05). In children with random serum total cortisol greater than 18 µg/dL, stress dose hydrocortisone was associated with greater PICU mortality and fewer ventilator-free days and vasopressor-free days (all p < 0.05). CONCLUSIONS: Stress dose hydrocortisone therapy in children with catecholamine-dependent septic shock correlated more with severity of illness than random serum total cortisol levels and was associated with worse outcomes, irrespective of random serum total cortisol levels.

RESUMEN

OBJECTIVE: To test the association between random cortisol and severity of illness in a "real-world" application of current guidelines. STUDY DESIGN: We performed a secondary analysis of a prospective observational cohort of acute respiratory distress syndrome (ARDS). Children with ARDS and vasopressor-dependent shock were identified and random cortisol levels before potential hydrocortisone initiation recorded. The cohort was dichotomized to cortisol < 18 and ≥ 18 µg/dL, and hydrocortisone use and outcomes compared. RESULTS: Of 357 children with ARDS, 155 (15 nonsurvivors; 10%) had vasopressors initiated with cortisol drawn before possible hydrocortisone use. Patients with cortisol < 18 µg/dL had lower severity of illness scores, fewer organ failures, and lower vasopressor scores (all rank-sum P < .05). No benefit was seen with hydrocortisone in either the entire cohort, or when dichotomized by a cortisol cutoff of 18 µg/dL. In patients with cortisol ≥ 18 µg/dL, hydrocortisone was associated with increased mortality after adjustment for either organ dysfunction or vasopressor score. CONCLUSIONS: In children with ARDS with vasopressor-dependent shock, low cortisol correlated with lower severity of illness. Random cortisol was a poor method of diagnosing adrenal insufficiency, and a strategy of hydrocortisone replacement for cortisol < 18 µg/dL did not target a population likely to benefit from hydrocortisone. Future guidelines should reconsider using random cortisol levels alone for assessing adrenal function.

RESUMEN

OBJECTIVES: Hyperglycemia is common and may be a risk factor for nosocomial infections, including central catheter-associated bloodstream infections in critically ill children. It is unknown whether hyperglycemia at the time of acquiring central catheter-associated bloodstream infections in pediatric critical illness is associated with worse outcomes. We hypothesized that hyperglycemia (blood glucose concentration > 126 mg/dL [> 7 mmol/L]) at the time of acquiring central catheter-associated bloodstream infections (from 4 d prior to the day of first positive blood culture, i.e., central catheter-associated bloodstream infections) in critically ill children is common and associated with ICU mortality. DESIGN: Retrospective observational cohort study. SETTING: Fifty-five-bed PICU and 26-bed cardiac ICU at an academic freestanding children's hospital. PATIENTS: One hundred sixteen consecutively admitted critically ill children from January 1, 2008, to June 30, 2012, who were 0-21 years with central catheter-associated bloodstream infections were included. We excluded children with diabetes mellitus, metabolic disorders, and those with a "do not attempt resuscitation" order. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The study cohort had an overall ICU mortality of 23%, with 48% of subjects developing hyperglycemia at the time of acquiring central catheter-associated bloodstream infections. Compared with survivors, nonsurvivors experienced more hyperglycemia both at the time of acquiring central catheter-associated bloodstream infections and subsequently. Median blood glucose at the time of acquiring central catheter-associated bloodstream infections was higher in nonsurvivors compared with survivors (139.5 mg/dL [7.7 mmol/L] vs 111 mg/dL [6.2 mmol/L]; p < 0.001) with 70% of nonsurvivors experiencing blood glucose greater than 126 mg/dL (> 7 mmol/L) during the 7 days following central catheter-associated bloodstream infections (in comparison to 45% of survivors; p = 0.03). After controlling for severity of illness and interventions, hyperglycemia at the time of acquiring central catheter-associated bloodstream infections was independently associated with ICU mortality (adjusted odds ratio, 1.9; 95% CI, 1.1-6.4; p = 0.03), in addition to other risk factors for ICU mortality (vasopressor use and severity of organ dysfunction). CONCLUSIONS: Hyperglycemia at the time of acquiring central catheter-associated bloodstream infections is common and associated with ICU mortality in critically ill children. Strategies to monitor and control blood glucose to avoid hyperglycemia may improve outcomes in critically ill children experiencing central catheter-associated bloodstream infections.
