Implementation of a Novel Seizure Assessment Tool for Unified Seizure Evaluation Improves Nurse Response.

ABSTRACT: BACKGROUND: Ictal and postictal testing is an essential aspect of clinical care when diagnosing and treating seizures. The epilepsy monitoring unit (EMU) has standard operating procedures for nursing care during and after seizure events, but there is limited interrater reliability. Streamlining ictal and postictal testing processes may enhance care consistency for patients in the EMU unit. The purpose of this study was to create an ictal and postictal seizure assessment tool that would increase the consistency of nursing assessment for EMU patients. METHODS: This prospective study had 4 phases: baseline assessment, instrument development, staff education, and field testing. During baseline assessment, an advanced practice provider and an epilepsy fellow graded nurse ictal and postictal assessment via survey questions. After instrument development, education, and implementation, the same survey was administered to determine if nursing consistency in assessing seizure events improved. The tool used in this study was created by a team of clinical experts to ensure consistency in the assessment of seizure patients. RESULTS: A total of 58 first seizure events were collected over a 6-month intervention period; 27 in the pretest and 31 in the posttest. Paired t test analyses revealed significant improvement in the clinical testing domains of verbal language function (P < .005), motor function (P < .0005), and item assessment order (P < .005) postintervention. There was nonsignificant improvement in the domains of responsiveness (feeling [P = .597], using a code word [P = .093]) and visual language function (P = .602). CONCLUSION: The data captured in this study support the need for this instrument. There is strong need to increase consistency in assessing seizure events and to promote continued collaboration among clinical teams to enhance care to EMU patients. Validation of this instrument will further improve team collaboration by allowing nurses to contribute to their fullest extent.

Clinical outcome and cost effectiveness of acute ischemic stroke transfers for endovascular reperfusion therapy from geographically distant counties: Stroke transfer outcomes.

OBJECTIVES: Endovascular reperfusion therapy (EVT) for acute ischemic stroke (AIS) with large vessel occlusion (LVO) has resulted in increased patient transfers to comprehensive stroke centers (CSCs). Clinical outcomes including the financial impact of these transfers from geographically dispersed population are lacking. Hence, we studied outcomes and cost-effectiveness of stroke transfers from remote areas. MATERIALS AND METHODS: We used a 3-year cohort of AIS patients transferred from geographically dispersed counties (<100 mi., 101-200 mi., and >200 mi.). A 3-month modified Rankin scale (mRS) score of 0-2 defined a favorable clinical outcome. Cost-effectiveness is studied by calculating the incremental cost effectiveness ratio, using hospital costs reimbursed data and utility-weighted (UW)-mRS. RESULTS: Among 172 patients transferred for EVT, patients transferred from nearby counties were more likely to undergo intervention compared to other counties (56.9 % vs. 36.7 % vs. 49.2 % p = .11). Irrespective of proximity (in mi.) to CSC [21.5 (14-56.3)] vs. 185 (137-185) vs. 349 (325-355)], there was a similar delay (in min.) to arrival from all locations [321.5 (244-490), 366 (298-432), and 460 (385-554.5) respectively], but no statistically significant differences in favorable outcomes (18.0 %, 34.1 %, and 22.2 %, respectively, p = .41). Patients undergoing EVT had higher hospital costs reimbursed compared to non-EVT patients [$37,303 (25,745-40,658) vs. $14,008 (8,640-21,273) respectively, p < .001] and no statistically significant difference in UW-mRS [0.32 (0.06-0.56) vs. 0.06 (0-0.56), p = .30]. CONCLUSIONS: Our study identifies a need for targeted interventions to improve community awareness and optimize systems of care to improve outcomes and cost-effectiveness of EVT.

Anisocoria After Direct Light Stimulus is Associated with Poor Outcomes Following Acute Brain Injury.

BACKGROUND: Assessing pupil size and reactivity is the standard of care in neurocritically ill patients. Anisocoria observed in critically ill patients often prompts further investigation and treatment. This study explores anisocoria at rest and after light stimulus determined using quantitative pupillometry as a predictor of discharge modified Rankin Scale (mRS) scores. METHODS: This analysis includes data from an international registry and includes patients with paired (left and right eye) quantitative pupillometry readings linked to discharge mRS scores. Anisocoria was defined as the absolute difference in pupil size using three common cut points (> 0.5 mm, > 1 mm, and > 2 mm). Nonparametric models were constructed to explore patient outcome using three predictors: the presence of anisocoria at rest (in ambient light); the presence of anisocoria after light stimulus; and persistent anisocoria (present both at rest and after light). The primary outcome was discharge mRS score associated with the presence of anisocoria at rest versus after light stimulus using the three commonly defined cut points. RESULTS: This analysis included 152,905 paired observations from 6,654 patients with a mean age of 57.0 (standard deviation 17.9) years, and a median hospital stay of 5 (interquartile range 3-12) days. The mean admission Glasgow Coma Scale score was 12.7 (standard deviation 3.5), and the median discharge mRS score was 2 (interquartile range 0-4). The ranges for absolute differences in pupil diameters were 0-5.76 mm at rest and 0-6.84 mm after light. Using an anisocoria cut point of > 0.5 mm, patients with anisocoria after light had worse median mRS scores (2 [interquartile range 0-4]) than patients with anisocoria at rest (1 [interquartile range 0-3]; P < .0001). Patients with persistent anisocoria had worse median mRS scores (3 [interquartile range 1-4]) than those without persistent anisocoria (1 [interquartile range 0-3]; P < .0001). Similar findings were observed using a cut point for anisocoria of > 1 mm and > 2 mm. CONCLUSIONS: Anisocoria after light is a new biomarker that portends worse outcome than anisocoria at rest. After further validation, anisocoria after light should be considered for inclusion as a reported and trended assessment value.

Neurologic Quality of Life Outcomes in Patients with Normal Pressure Hydrocephalus After Ventriculoperitoneal Shunt Placement: A Prospective Assessment of Cognition, Mobility, and Social Participation.

BACKGROUND: Idiopathic normal pressure hydrocephalus (iNPH) typically presents with gait disturbances, cognitive decline, and urinary incontinence. Symptomatic improvement generally occurs following shunt placement, but limited evidence exists on the quality of life (QOL) metrics in iNPH. Therefore, we conducted a prospective study of the effect of shunt placement on QOL in iNPH patients, using Quality of Life in Neurologic Disorders (Neuro-QOL) metrics. METHODS: Eligible patients underwent shunt placement after evidence of symptomatic improvement following temporary cerebrospinal fluid diversion via inpatient lumbar drain trial. Patients were administered short- and long-form Neuro-QOL assessments prior to shunt placement and at 6-month and 1-year postoperative timepoints to evaluate lower extremity mobility, cognitive function, and social roles and activities participation. Changes in QOL measures were analyzed using a repeated-measures linear mixed effects model. RESULTS: There were 48 patients with a mean age of 75.4 ± 6.3 years. Average short-form mobility scores improved by 3.9 points (14.6%) at 6-month follow-up and by 6.2 points (23.2%) at 1-year follow-up compared with preoperative baseline (P = 0.027 and P = 0.0002, respectively). Short-form cognition scores increased by 5.2 points (22.4%) at 6 months and 10.9 points (47.0%) at 1 year postoperatively (P = 0.007 and P < 0.0001, respectively). On long-form assessment, social roles and activity participation scores improved by 29.3 points (23.4%) at 6 months and 31.6 points (25.2%) at 1 year after surgery compared to baseline (P = 0.028 and P = 0.02, respectively). CONCLUSIONS: Our findings demonstrate that shunt placement leads to improved QOL in iNPH patients across multiple domains. Significant improvements in mobility, cognition, and social roles and activity participation are realized within the first 6 months and are sustained on 1-year follow-up.

Door to needle time trends after transition to tenecteplase: A Multicenter Texas stroke registry.

BACKGROUND: Tenecteplase (TNK) is considered a promising option for the treatment of acute ischemic stroke (AIS) with the potential to decrease door-to-needle times (DTN). This study investigates DTN metrics and trends after transition to tenecteplase. METHODS: The Lone Star Stroke (LSS) Research Consortium TNK registry incorporated data from three Texas hospitals that transitioned to TNK. Subject data mapped to Get-With-the-Guidelines stroke variables from October 1, 2019 to March 31, 2023 were limited to patients who received either alteplase (ALT) or TNK within the 90 min DTN times. The dataset was stratified into ALT and TNK cohorts with univariate tables for each measured variable and further analyzed using descriptive statistics. Logistic regression models were constructed for both ALT and TNK to investigate trends in DTN times. RESULTS: In the overall cohort, the TNK cohort (n = 151) and ALT cohort (n = 161) exhibited comparable population demographics, differing only in a higher prevalence of White individuals in the TNK cohort. Both cohorts demonstrated similar clinical parameters, including mean NIHSS, blood glucose levels, and systolic blood pressure at admission. In the univariate analysis, no difference was observed in median DTN time within the 90 min time window compared to the ALT cohort [40 min (30-53) vs 45 min (35-55); P = .057]. In multivariable models, DTN times by thrombolytic did not significantly differ when adjusting for NIHSS, age (P = .133), or race and ethnicity (P = .092). Regression models for the overall cohort indicate no significant DTN temporal trends for TNK (P = .84) after transition; nonetheless, when stratified by hospital, a single subgroup demonstrated a significant DTN upward trend (P = 0.002). CONCLUSION: In the overall cohort, TNK and ALT exhibited comparable temporal trends and at least stable DTN times. This indicates that the shift to TNK did not have an adverse impact on the DTN stroke metrics. This seamless transition is likely attributed to the similarity of inclusion and exclusion criteria, as well as the administration processes for both medications. When stratified by hospital, the three subgroups demonstrated variable DTN time trends which highlight the potential for either fatigue or unpreparedness when switching to TNK. Because our study included a multi-ethnic cohort from multiple large Texas cities, the stable DTN times after transition to TNK is likely applicable to other healthcare systems.

Quantitative Pupillometry: Clinical Applications for the Internist.

From the time of Galen, examination of the pupillary light reflex has been a standard of care across the continuum of health care. The growing body of evidence overwhelmingly supports the use of quantitative pupillometry over subjective examination with flashlight or penlight. At current time, pupillometers have become standard of care in many hospitals across 6 continents. This review paper provides an overview and rationale for pupillometer use and highlights literature supporting pupillometer-derived measures of the pupillary light reflex in both neurological and non-neurological patients across the health care continuum.

The Presence of Blood in a Strain Gauge Pressure Transducer Has a Clinical Effect on the Accuracy of Intracranial Pressure Readings.

IMPORTANCE: Patients admitted with cerebral hemorrhage or cerebral edema often undergo external ventricular drain (EVD) placement to monitor and manage intracranial pressure (ICP). A strain gauge transducer accompanies the EVD to convert a pressure signal to an electrical waveform and assign a numeric value to the ICP. OBJECTIVES: This study explored ICP accuracy in the presence of blood and other viscous fluid contaminates in the transducer. DESIGN: Preclinical comparative design study. SETTING: Laboratory setting using two Natus EVDs, two strain gauge transducers, and a sealed pressure chamber. PARTICIPANTS: No human subjects or animal models were used. INTERVENTIONS: A control transducer primed with saline was compared with an investigational transducer primed with blood or with saline/glycerol mixtures in mass:mass ratios of 25%, 50%, 75%, and 100% glycerol. Volume in a sealed chamber was manipulated to reflect changes in ICP to explore the impact of contaminates on pressure measurement. MEASUREMENTS AND MAIN RESULTS: From 90 paired observations, ICP readings were statistically significantly different between the control (saline) and experimental (glycerol or blood) transducers. The time to a stable pressure reading was significantly different for saline vs. 25% glycerol (< 0.0005), 50% glycerol (< 0.005), 75% glycerol (< 0.0001), 100% glycerol (< 0.0005), and blood (< 0.0005). A difference in resting stable pressure was observed for saline vs. blood primed transducers (0.041). CONCLUSIONS AND RELEVANCE: There are statistically significant and clinically relevant differences in time to a stable pressure reading when contaminates are introduced into a closed drainage system. Changing a transducer based on the presence of blood contaminate should be considered to improve accuracy but must be weighed against the risk of introducing infection.

An Update on Curing Coma Campaign.

The Curing Coma Campaign (CCC) and its contributing collaborators identified multiple key areas of knowledge and research gaps in coma and disorders of consciousness (DoC). This step was a crucial effort and essential to prioritize future educational and research efforts. These key areas include defining categories of DoC, assessing DoC using multimodal approach (e.g., behavioral assessment tools, advanced neuroimaging studies), discussing optimal clinical trials' design and exploring computational models to conduct clinical trials in patients with DoC, and establishing common data elements to standardize data collection. Other key areas focused on creating coma care registry and educating clinicians and patients and promoting awareness of DoC to improve care in patients with DoC. The ongoing efforts in these key areas are discussed.

Stroke Screening Process for Spanish-Speaking Patients.

INTRODUCTION: The Balance Eyes Face Arms Speech Time stroke screening tool may have limitations for Spanish-speaking individuals. The purpose of this study is to identify potential screen failure events during evaluation for intervenable acute ischemic stroke events among Spanish-speaking patients. METHODS: This is a retrospective, observational, single-center study at an urban academic center during 2020. Patients with a positive stroke screen were stratified by Spanish or non-Spanish. We measured last known well, sensitivity, specificity, negative predictive value, and positive predictive value of the emergency department provider's decision to escalate to complete stroke evaluation with acute ischemic stroke as the outcome of interest. RESULTS: Among 796 patients (mean age of 52 years, 56% female, 37% Spanish speaking), 30% of patients with positive stroke screen were converted to complete stroke evaluation. For provider escalation to complete stroke evaluation for the outcome of acute ischemic stroke events, prevalence was 13%, sensitivity 81%, positive predictive value 22%, and negative predictive value 97% for the overall sample. Spanish-speaking patients were less likely to progress from screening to complete stroke evaluation (25.8% vs 32.8%; 95% for difference CI, 0.57-13.5). Importantly, there was no difference in rate of acute ischemic stroke between Spanish- and non-Spanish-speaking patients. DISCUSSION: Over 1 year, with 796 patients triggered at triage by Balance Eyes Face Arms Speech Time for positive stroke screens, only 13% resulted in an acute ischemic stroke. Spanish-speaking patients were less likely to progress from screening to complete stroke evaluation, but the rate of acute ischemic stroke was not different by language.

Validation of a Novel Neurologic Assessment Test for Healthcare Staff.

ABSTRACT: BACKGROUND: To measure the effectiveness of an educational intervention, it is essential to develop high-quality, validated tools to assess a change in knowledge or skills after an intervention. An identified gap within the field of neurology is the lack of a universal test to examine knowledge of neurological assessment. METHODS: This instrument development study was designed to determine whether neuroscience knowledge as demonstrated in a Neurologic Assessment Test (NAT) was normally distributed across healthcare professionals who treat patients with neurologic illness. The variables of time, knowledge, accuracy, and confidence were individually explored and analyzed in SAS. RESULTS: The mean (standard deviation) time spent by 135 participants to complete the NAT was 12.9 (3.2) minutes. The mean knowledge score was 39.5 (18.2), mean accuracy was 46.0 (15.7), and mean confidence was 84.4 (24.4). Despite comparatively small standard deviations, Shapiro-Wilk scores indicate that the time spent, knowledge, accuracy, and confidence are nonnormally distributed ( P < .0001). The Cronbach α was 0.7816 considering all 3 measures (knowledge, accuracy, and confidence); this improved to an α of 0.8943 when only knowledge and accuracy were included in the model. The amount of time spent was positively associated with higher accuracy ( r2 = 0.04, P < .05), higher knowledge was positively associated with higher accuracy ( r2 = 0.6543, P < .0001), and higher knowledge was positively associated with higher confidence ( r2 = 0.4348, P < .0001). CONCLUSION: The scores for knowledge, confidence, and accuracy each had a slightly skewed distribution around a point estimate with a standard deviation smaller than the mean. This suggests initial content validity in the NAT. There is adequate initial construct validity to support using the NAT as an outcome measure for projects that measure change in knowledge. Although improvements can be made, the NAT does have adequate construct and content validity for initial use.

Implementing a Critical Thinking Tool to Evaluate Educational Needs for Inpatient Rehabilitation Nurses.

ABSTRACT: BACKGROUND: Most critical thinking assessment tools are resource intensive and require significant time and money to administer. Moreover, these tools are not tailored to evaluate critical thinking skills among inpatient rehabilitation facility (IRF) nurses. This pilot study explores the efficacy of using short videos to evaluate critical thinking for nurses working in an IRF. METHODS: We developed and filmed 3 clinical scenarios representative of common IRF events that require critical thinking on behalf of the nurse. Thirty-one IRF nurses participated in the study and independently scored their own critical thinking skills using a visual analog scale. Using the same scale, nurse managers and assistant managers who worked closely with the nurses also rated the critical thinking ability of each nurse. The nurse then viewed and responded in narrative form to each of the 3 videos. A scoring rubric was used to independently evaluate the critical thinking skills for each nurse based on the nurses' responses. RESULTS: Nurses rated their own critical thinking skills higher than mangers rated them (m = 85.23 vs 62.89). There was high interrater reliability for scoring video 1k (0.65), video 2k (0.90), and video 3k (0.84). CONCLUSION: The results demonstrate efficacy for further study of low-cost alternatives to evaluate critical thinking among neuroscience nurses providing IRF care.

Guidelines for Seizure Prophylaxis in Adults Hospitalized with Moderate-Severe Traumatic Brain Injury: A Clinical Practice Guideline for Health Care Professionals from the Neurocritical Care Society.

BACKGROUND: There is practice heterogeneity in the use, type, and duration of prophylactic antiseizure medications (ASMs) in patients with moderate-severe traumatic brain injury (TBI). METHODS: We conducted a systematic review and meta-analysis of articles assessing ASM prophylaxis in adults with moderate-severe TBI (acute radiographic findings and requiring hospitalization). The population, intervention, comparator, and outcome (PICO) questions were as follows: (1) Should ASM versus no ASM be used in patients with moderate-severe TBI and no history of clinical or electrographic seizures? (2) If an ASM is used, should levetiracetam (LEV) or phenytoin/fosphenytoin (PHT/fPHT) be preferentially used? (3) If an ASM is used, should a long versus short (> 7 vs. ≤ 7 days) duration of prophylaxis be used? The main outcomes were early seizure, late seizure, adverse events, mortality, and functional outcomes. We used Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology to generate recommendations. RESULTS: The initial literature search yielded 1998 articles, of which 33 formed the basis of the recommendations: PICO 1: We did not detect any significant positive or negative effect of ASM compared to no ASM on the outcomes of early seizure, late seizure, adverse events, or mortality. PICO 2: We did not detect any significant positive or negative effect of PHT/fPHT compared to LEV for early seizures or mortality, though point estimates suggest fewer late seizures and fewer adverse events with LEV. PICO 3: There were no significant differences in early or late seizures with longer versus shorter ASM use, though cognitive outcomes and adverse events appear worse with protracted use. CONCLUSIONS: Based on GRADE criteria, we suggest that ASM or no ASM may be used in patients hospitalized with moderate-severe TBI (weak recommendation, low quality of evidence). If used, we suggest LEV over PHT/fPHT (weak recommendation, very low quality of evidence) for a short duration (≤ 7 days, weak recommendation, low quality of evidence).

Guidelines for seizure prophylaxis in adults hospitalized with moderate­severe traumatic brain injury: a clinical practice guideline for health care professionals from the Neurocritical Care Society

There is practice heterogeneity in the use, type, and duration of prophylactic antiseizure medications (ASMs) in patients with moderate­severe traumatic brain injury (TBI).

Prospective study examining the impact of cerebral angiography on quantitative pupillometer values in the interventional radiology suite.

OBJECTIVES: The purpose of this pilot study was to obtain baseline quantitative pupillometry (QP) measurements before and after catheter-directed cerebral angiography (DCA) to explore the hypothesis that cerebral angiography is an independent predictor of change in pupillary light reflex (PLR) metrics. DESIGN: This was a prospective, observational pilot study of PLR assessments obtained using QP 30 min before and after DCA. All patients had QP measurements performed with the NPi-300 (Neuroptics) pupillometer. SETTING: Recruitment was done at a single-centre, tertiary-care academic hospital and comprehensive stroke centre in Dallas, Texas. PARTICIPANTS: Fifty participants were recruited undergoing elective or emergent angiography. Inclusion criteria were a physician-ordered interventional neuroradiological procedure, at least 18 years of age, no contraindications to PLR assessment with QP, and nursing transport to and from DCA. Patients with a history of eye surgery were excluded. MAIN OUTCOME MEASURES: Difference in PLR metric obtained from QP 30 min before and after DCA. RESULTS: Statistically significant difference was noted in the pre and post left eye readings for the minimum pupil size (a.k.a., pupil diameter on maximum constriction). The mean maximum constriction diameter prior to angiogram of 3.2 (1.1) mm was statistically larger than after angiogram (2.9 (1.0) mm; p<0.05); however, this was not considered clinically significant. Comparisons for all other PLR metrics pre and post angiogram demonstrated no significant difference. Using change in NPi pre and post angiogram (Δpre=0.05 (0.77) vs Δpost=0.08 (0.67); p=0.62), we calculated the effect size as 0.042. Hence, detecting a statistically significant difference in NPi, if a difference exists, would require a sample size of ~6000 patients. CONCLUSIONS: Our study provides supportive data that in an uncomplicated angiogram, even with intervention, there is no effect on the PLR.

Multicenter exploration of tenecteplase transition factors: A quantitative analysis.

BACKGROUND: Tenecteplase (TNK) is gaining recognition as a novel therapy for acute ischemic stroke (AIS). Despite TNK offering a longer half-life, time and cost saving benefits and comparable treatment and safety profiles to Alteplase (ALT), the adoption of TNK as a treatment for AIS presents challenges for hospital systems. OBJECTIVE: Identify barriers and facilitators of TNK implementation at acute care hospitals in Texas. METHODS: This prospective survey used open-ended questions and Likert statements generated from content experts and informed by qualitative research. Stroke clinicians and nurses working at 40 different hospitals in Texas were surveyed using a virtual platform. RESULTS: The 40 hospitals had a median of 34 (IQR 24.5-49) emergency department beds and 42.5 (IQR 23.5-64.5) inpatient stroke beds with 506.5 (IQR 350-797.5) annual stroke admissions. Fifty percent of the hospitals were Comprehensive Stroke Centers, and 18 (45 %) were solely using ALT for treatment of eligible AIS patients. Primary facilitators to TNK transition were team buy-in and a willingness of stroke physicians, nurses, and pharmacists to adopt TNK. Leading barriers were lack of clinical evidence supporting TNK safety profile inadequate evidence supporting TNK use and a lack of American Heart Association guidelines support for TNK administration in all AIS cases. CONCLUSION: Understanding common barriers and facilitators to TNK adoption can assist acute care hospitals deciding to implement TNK as a treatment for AIS. These findings will be used to design a TNK adoption Toolkit, utilizing implementation science techniques, to address identified obstacles and to leverage facilitators.

Use of Family Photographs Reduces Restlessness in Neurocritical Care Patients.

ABSTRACT: BACKGROUND: Patients admitted to the neuroscience intensive care unit often experience varying states of confusion and restlessness. The purpose of this study was to examine restlessness in acutely confused patients through use of familiar photographs. METHODS : This randomized prospective pilot study placed family photographs (photos) on the bedrail of confused patients during the night shift (8 pm to 4 am ) in a neuroscience intensive care unit. Wrist actigraphy was used to examine restlessness when patients were turned to face the photos versus when they were not facing the photos. RESULTS: The 20 patients enrolled provided 34 nights worth of data during which 32 640 actigraph readings were obtained. On the first night of study, the odds of wrist movement were higher when the patient was facing the photos compared with not (odds ratio, 1.51; 95% confidence interval, 1.42-1.61). During subsequent nights, the odds of wrist movement were lower when the patient was facing the photos compared with not (odds ratio, 0.82; 95% confidence interval, 0.75-0.90). CONCLUSION : Use of familiar photos does not change restlessness, agitation, or delirium on the first night of observation. However, the use of familiar photos may decrease restlessness on the subsequent nights. There are important subjective observations from researchers and family that suggest all subjects had a noticeable response when initially seeing the familiar photos.
