Objective To determine prevalence of delirium in critically-ill children and explore associated risk factors. Design Multi-institutional point-prevalence study. Setting Twenty-five pediatric critical care units in the United States, the Netherlands, New Zealand, Australia, and Saudi Arabia. Patients All children admitted to the pediatric critical care units on designated study days (n=994). Intervention Children were screened for delirium using the Cornell Assessment of Pediatric Delirium (CAPD) by the bedside nurse. Demographic and treatment-related variables were collected. Measurements and Main Results Primary study outcome measure was prevalence of delirium. In 159 children, a final determination of mental status could not be ascertained. Of the 835 remaining subjects, 25% screened positive for delirium, 13% were classified as comatose, and 62% were delirium-free and coma-free. Delirium prevalence rates varied significantly with reason for ICU admission, with highest delirium rates found in children admitted with an infectious or inflammatory disorder. For children who were in the PICU for 6 or more days, delirium prevalence rate was 38%. In a multivariate model, risk factors independently associated with development of delirium included age < 2 years, mechanical ventilation, benzodiazepines, narcotics, use of physical restraints, and exposure to vasopressors and anti-epileptics. Conclusions Delirium is a prevalent complication of critical illness in children, with identifiable risk factors. Further multi-institutional, longitudinal studies are required to investigate effect of delirium on long-term outcomes, and possible preventive and treatment measures. Universal delirium screening is practical and can be implemented in pediatric critical care units.

Objective To determine the effect of therapeutic plasma exchange (TPE) on hemodynamics, organ failure, and survival in children with multiple organ dysfunction syndrome (MODS) due to sepsis requiring extracorporeal life support (ECLS). Design A retrospective analysis. Setting A pediatric intensive care unit (PICU) in an academic children’s hospital. Patients 14 consecutive children with sepsis and MODS who received TPE while on ECLS from 2005 to 2013. Interventions Median of 3 cycles of TPE with median of 1.0 times the estimated plasma volume per exchange. Measurements and Main Results Organ Failure Index (OFI) and Vasoactive-Inotropic Score (VIS) were measured before and after TPE use. PICU survival in our cohort was 71.4%. OFI decreased in patients following TPE [pre: 4.1 ± 0.7 vs. post: 2.9 ± 0.9 (mean ±SD); p = 0.0004]. Patients showed improved VIS following TPE [pre: 24.5 (13.0–69.8) vs. post: 5.0 (1.5–7.0), median (25th–75th); p = 0.0002]. Among all patients, the change in OFI was greater for early TPE use than late use [pre: −1.7 ±1.2 vs. post: −0.9 ±0.6; p = 0.14], similar to the change in VIS [pre: −67.5 (28.0–171.2) vs. post: −12.0 (7.2–18.5); p = 0.02]. Among survivors, the change in OFI was greater among early TPE use than late use [early: −2.3 ±1.0 vs. late: −0.8 ± 0.8; p = 0.03], as was the change in VIS [early: −42.0 (16.0–76.3) vs. late: −12.0 (5.3–29.0); p=0.17]. The mean duration of ECLS after TPE according to timing of TPE was not statistically different among all patients or among survivors. Conclusions The use of TPE in children on ECLS with sepsis-induced MODS is associated with organ failure recovery and improved hemodynamic status. Initiating TPE early in the hospital course was associated with greater improvement in organ dysfunction and decreased requirement for vasoactive and/or inotropic agents.

Substantial noise pollution exists in our PICU, and utilizing the pediatric delirium bundle led to a significant noise reduction that can be perceived as half the loudness with hourly nighttime average dB meeting the EPA standards when compliant with the bundle.

Objectives: With decreasing mortality in PICUs, a growing number of survivors experience long-lasting physical impairments. Early physical rehabilitation and mobilization during critical illness are safe and feasible, but little is known about the prevalence in PICUs. We aimed to evaluate the prevalence of rehabilitation for critically ill children and associated barriers. Design: National 2-day point prevalence study. Setting: Eighty-two PICUs in 65 hospitals across the United States. Patients: All patients admitted to a participating PICU for greater than or equal to 72 hours on each point prevalence day. Interventions: None. Measurements and Main Results: The primary outcome was prevalence of physical therapy– or occupational therapy–provided mobility on the study days. PICUs also prospectively collected timing of initial rehabilitation team consultation, clinical and patient mobility data, potential mobility–associated safety events, and barriers to mobility. The point prevalence of physical therapy– or occupational therapy–provided mobility during 1,769 patient-days was 35% and associated with older age (adjusted odds ratio for 13–17 vs < 3 yr, 2.1; 95% CI, 1.5–3.1) and male gender (adjusted odds ratio for females, 0.76; 95% CI, 0.61–0.95). Patients with higher baseline function (Pediatric Cerebral Performance Category, ≤ 2 vs > 2) less often had rehabilitation consultation within the first 72 hours (27% vs 38%; p < 0.001). Patients were completely immobile on 19% of patient-days. A potential safety event occurred in only 4% of 4,700 mobility sessions, most commonly a transient change in vital signs. Out-of-bed mobility was negatively associated with the presence of an endotracheal tube (adjusted odds ratio, 0.13; 95% CI, 0.1–0.2) and urinary catheter (adjusted odds ratio, 0.28; 95% CI, 0.1–0.6). Positive associations included family presence in children less than 3 years old (adjusted odds ratio, 4.55; 95% CI, 3.1–6.6). Conclusions: Younger children, females, and patients with higher baseline function less commonly receive rehabilitation in U.S. PICUs, and early rehabilitation consultation is infrequent. These findings highlight the need for systematic design of rehabilitation interventions for all critically ill children at risk of functional impairments.

This study examined whether age and brachial-ankle pulse-wave velocity (baPWV) can be predicted with ultra-wide-field pseudo-color (UWPC) images using deep learning (DL). We examined 170 UWPC images of both eyes of 85 participants (40 men and 45 women, mean age: 57.5 ± 20.9 years). Three types of images were included (total, central, and peripheral) and analyzed by k-fold cross-validation (k = 5) using Visual Geometry Group-16. After bias was eliminated using the generalized linear mixed model, the standard regression coefficients (SRCs) between actual age and baPWV and predicted age and baPWV from the UWPC images by the neural network were calculated, and the prediction accuracies of the DL model for age and baPWV were examined. The SRC between actual age and predicted age by the neural network was 0.833 for all images, 0.818 for central images, and 0.649 for peripheral images (all P < 0.001) and between the actual baPWV and the predicted baPWV was 0.390 for total images, 0.419 for central images, and 0.312 for peripheral images (all P < 0.001). These results show the potential prediction capability of DL for age and vascular aging and could be useful for disease prevention and early treatment.

IMPORTANCE Family-centered care, which supports family presence (FP) during procedures, is now a widely accepted standard at health care facilities that care for children. However, there is a paucity of data regarding the practice of FP during tracheal intubation (TI) in pediatric intensive care units (PICUs). Family presence during procedures in PICUs has been advocated.OBJECTIVE To describe the current practice of FP during TI and evaluate the association with procedural and clinician (including physician, respiratory therapist, and nurse practitioner) outcomes across multiple PICUs. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study in which all TIs from July 2010 to March 2014 in the multicenter TI database (National Emergency Airway Registry for Children [NEAR4KIDS]) were analyzed. Family presence was defined as a family member present during TI. This study included all TIs in patients younger than 18 years in 22 international PICUs.EXPOSURES Family presence and no FP during TI in the PICU. MAIN OUTCOMES AND MEASURESThe percentage of FP during TIs. First attempt success rate, adverse TI-associated events, multiple attempts (Ն3), oxygen desaturation (oxygen saturation as measured by pulse oximetry <80%), and self-reported team stress level.RESULTS A total of 4969 TI encounters were reported. Among those, 81% (n = 4030) of TIs had documented FP status (with/without). The median age of participants with FP was 2 years and 1 year for those without FP. The average percentage of TIs with FP was 19% and varied widely across sites (0%-43%; P < .001). Tracheal intubations with FP (vs without FP) were associated with older patients (median, 2 years vs 1 year; P = .04), lower Paediatric Index of Mortality 2 score, and pediatric resident as the first airway clinician (23%, n = 179 vs 18%, n = 584; odds ratio [OR], 1.4; 95% CI, 1.2-1.7). Tracheal intubations with FP and without FP were no different in the first attempt success rate (OR, 1.00; 95% CI, 0.85-1.18), adverse TI-associated events (any events: OR, 1.06; 95% CI, 0.85-1.30 and severe events: OR, 1.04; 95% CI, 0.75-1.43), multiple attempts (Ն3) (OR, 1.03; 95% CI, 0.82-1.28), oxygen desaturation (oxygen saturation <80%) (OR, 0.97; 95% CI, 0.80-1.18), or self-reported team stress level (OR, 1.09; 95% CI, 0.92-1.31). This result persisted after adjusting for patient and clinician confounders.CONCLUSIONS AND RELEVANCE Wide variability exists in FP during TIs across PICUs. Family presence was not associated with first attempt success, adverse TI-associated events, oxygen desaturation (<80%), or higher team stress level. Our data suggest that FP during TI can safely be implemented as part of a family-centered care model in the PICU.
