Survey of Bedside Clinical Neurologic Assessments in U.S. PICUs.

ABSTRACT: OBJECTIVE:To understand how routine bedside clinical neurologic assessments are performed in U.S. PICUs. DESIGN:Electronic survey. SETTING:Academic PICUs throughout the United States. SUBJECTS:Faculty representatives from PICUs throughout the United States. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:We surveyed how routine bedside neurologic assessments are reported to be performed in U.S. PICUs and the attitudes of respondents on the utility of these assessments. The survey contained questions regarding 1) components of neurologic assessments; 2) frequency of neurologic assessments; 3) documentation and communication of changes in neurologic assessment; and 4) optimization of neurologic assessments. Surveys were received from 64 of 67 institutions (96%). Glasgow Coma Scale and pupillary reflex were the most commonly reported assessments (80% and 92% of institutions, respectively). For patients with acute brain injury, 95% of institutions performed neurologic assessments hourly although assessment frequency was more variable for patients at low risk of developing brain injury and those at high risk for brain injury, but without overt injury. In 73% of institutions, any change detected on routine neuroassessment was communicated to providers, whereas in 27%, communication depended on the severity or degree of neurologic decline. Seventy percent of respondents thought that their current practice for assessing and monitoring neurologic status was suboptimal. Only 57% felt that the Glasgow Coma Scale was a valuable tool for the serial assessment of neurologic function in the ICU. Ninety-two percent felt that a standardized approach to assessing and documenting preillness neurologic function would be valuable. CONCLUSIONS:Routine neurologic assessments are reported to be conducted in nearly all academic PICUs in the United States with fellowship training programs although the content, frequency, and triggers for communication vary between institutions. Most physicians felt that the current paradigms for neurologic assessments are suboptimal. These data suggest that optimizing and standardizing routine bedside nursing neurologic assessments may be warranted.

Project description:OBJECTIVES:Despite little evidence, the practice of routine measurement of gastric residual volume to guide both the initiation and delivery of enteral feeding in PICUs is widespread internationally. In light of increased scrutiny of the evidence surrounding this practice, and as part of a trial feasibility study, we aimed to determine enteral feeding and gastric residual volume measurement practices in U.K. PICUs. DESIGN:An online survey to 27 U.K. PICUs. SETTING:U.K. PICUs. SUBJECTS:A clinical nurse, senior doctor, and dietician were invited to collaboratively complete one survey per PICU and send a copy of their unit guidelines on enteral feeding and gastric residual volume. INTERVENTIONS:None. MEASUREMENT AND MAIN RESULTS:Twenty-four of 27 units (89%) approached completed the survey. Twenty-three units (95.8%; 23/24) had written feeding guidelines, and 19 units (19/23; 83%) sent their guidelines for review. More units fed continuously (15/24; 62%) than intermittently (9/24; 37%) via the gastric route as their primary feeding method. All but one PICU routinely measured gastric residual volume, regardless of the method of feeding. Eighteen units had an agreed definition of feed tolerance, and all these included gastric residual volume. Gastric residual volume thresholds for feed tolerance were either volume based (mL/kg body weight) (11/21; 52%) or a percentage of the volume of feed administered (6/21; 29%). Yet only a third of units provided guidance about the technique of gastric residual volume measurement. CONCLUSIONS:Routine gastric residual volume measurement is part of standard practice in U.K. PICUs, with little guidance provided about the technique which may impact the accuracy of gastric residual volume. All PICUs that defined feed tolerance included gastric residual volume in the definition. This is important to know when proposing a standard practice arm of any future trial of no-routine gastric residual volume measurement in critically ill children.

Project description:BackgroundStyrene is an established neurotoxicant at occupational levels, but effects at levels relevant to the general population have not been studied. We examined the neurologic effects of environmental styrene exposure among U.S. Gulf coast residents.MethodsWe used National Air Toxics Assessment (NATA) 2011 estimates of ambient styrene concentrations to assign exposure levels for 21,962 non-diabetic Gulf state residents, and additionally measured blood styrene concentration in a subset of participants (n = 874). Neurologic symptoms, as well as detailed covariate information, were ascertained via telephone interview. We used log-binomial regression to estimate prevalence ratios (PR) and 95% confidence intervals (95% CI) for cross-sectional associations between both ambient and blood styrene levels and self-reported neurologic symptoms. We estimated associations independently for ten unique symptoms, as well as for the presence of any neurologic, central nervous system (CNS), or peripheral nervous system (PNS) symptoms. We also examined heterogeneity of associations with estimated ambient styrene levels by race and sex.ResultsOne-third of participants reported at least one neurologic symptom. The highest quartile of estimated ambient styrene was associated with one or more neurologic (PR, 1.12; 95% CI: 1.07,1.18), CNS (PR, 1.17; 95% CI: 1.11,1.25), and PNS (PR, 1.16; 95% CI: 1.09,1.25) symptom. Results were less consistent for biomarker analyses, but blood styrene level was suggestively associated with nausea (PR, 1.78; 95% CI: 1.04, 3.03). In stratified analyses, we observed the strongest effects among non-White participants.ConclusionsIncreasing estimated ambient styrene concentration was consistently associated with increased prevalence of neurologic symptoms. Associations between blood styrene levels and some neurologic symptoms were suggestive. Environmental styrene exposure levels may be sufficient to elicit symptomatic neurotoxic effects.

Project description:Clinicians are regularly faced with the difficult challenge of diagnosing consciousness after severe brain injury. As such, as many as 40% of minimally conscious patients who demonstrate fluctuations in arousal and awareness are known to be misdiagnosed as unresponsive/vegetative based on clinical consensus. Further, a significant minority of patients show evidence of hidden awareness not evident in their behavior. Despite this, clinical assessments of behavior are commonly used as bedside indicators of consciousness. Recent advances in functional high-density electroencephalography (hdEEG) have indicated that specific patterns of resting brain connectivity measured at the bedside are strongly correlated with the re-emergence of consciousness after brain injury. We report case studies of four patients with traumatic brain injury who underwent regular assessments of hdEEG connectivity and Coma Recovery Scale-Revised (CRS-R) at the bedside, as part of an ongoing longitudinal study. The first, a patient in an unresponsive wakefulness state (UWS), progressed to a minimally-conscious state several years after injury. HdEEG measures of alpha network centrality in this patient tracked this behavioral improvement. The second patient, contrasted with patient 1, presented with a persistent UWS diagnosis that paralleled with stability on the same alpha network centrality measure. Patient 3, diagnosed as minimally conscious minus (MCS-), demonstrated a significant late increase in behavioral awareness to minimally conscious plus (MCS+). This patient's hdEEG connectivity across the previous 18 months showed a trajectory consistent with this increase alongside a decrease in delta power. Patient 4 contrasted with patient 3, with a persistent MCS- diagnosis that was similarly tracked by consistently high delta power over time. Across these contrasting cases, hdEEG connectivity captures both stability and recovery of behavioral trajectories both within and between patients. Our preliminary findings highlight the feasibility of bedside hdEEG assessments in the rehabilitation context and suggest that they can complement clinical evaluation with portable, accurate and timely generation of brain-based patient profiles. Further, such hdEEG assessments could be used to estimate the potential utility of complementary neuroimaging assessments, and to evaluate the efficacy of interventions.
