Outcomes and Issues Addressed by Palliative Care in the Neurology Clinic.

Patients with neurological illnesses have many palliative care needs that need to be addressed in the outpatient clinical setting. This review discusses existing models of care delivery, including services delivered by neurology teams, palliative care specialists, telehealth, and home-based programs. We review the existing literature that supports these services and ongoing limitations that continue to create barriers to necessary clinical care for this vulnerable patient population.

Associations Between Baseline Total PTSD Symptom Severity, Specific PTSD Symptoms, and 3-Month Quality of Life in Neurologically Intact Neurocritical Care Patients and Informal Caregivers.

BACKGROUND: The objective is to pilot test the feasibility of assessing severity of posttraumatic stress disorder (PTSD) symptoms, as well as specific lower-order PTSD symptoms, experienced during neurological intensive care unit (neuro-ICU) admission and their relationship with 3-month quality of life (QoL) scores in multiple domains (i.e., physical, psychological, social, and environmental) in both patients and caregivers. METHODS: Between 2015 and 2016, we enrolled neurologically intact patients and informal caregivers of patients who reported demographics and PTSD symptoms (PTSD Checklist-Specific; PCL-S) during neuro-ICU admission and completed a QoL assessment (World Health Organization Quality of Life; WHOQOL-BREF) 3 months later. Clinical data were extracted from medical records. We ran two bivariate correlation matrices among PTSD symptom dimensions in patients and caregivers. Then, we used multiple linear regression to examine the prospective association of total PCL-S scores with each QoL domain in both patients and caregivers after adjusting for clinically important variables. Next, we explored differential associations between the 4 PTSD symptom dimensions and each QoL domain in both patients and caregivers, adjusting for sex and age. RESULTS: A total of 70 patients (45.7% women, 84.3% white, mean age 52.08 years) and 64 caregivers (64.1% women, 90.6% white, mean age 53.12 years) were included. PTSD symptom dimensions were moderately strongly correlated among patients (r = 0.65-0.79, p < 0.001) and caregivers (r = 0.55-0.78, p < 0.001). For both patients and caregivers, greater PTSD symptom severity was prospectively associated with lower QoL in all domains (ß = - 0.289 to - 0.622; p < 0.05). Our exploratory analysis revealed that greater numbing symptoms were associated with lower psychological QoL in patients (ß: - 0.397, p = 0.038), and lower physical (ß: - 0.409, p = 0.014), psychological (ß: - 0.519, p = 0.001), and social QoL (ß: - 0.704, p < 0.001) in caregivers. Greater re-experiencing symptoms were associated with lower physical QoL in both patients (ß: - 0.422, p = 0.047) and caregivers (ß: - 0.4, p = 0.041). CONCLUSIONS: Our preliminary results indicated that greater severity of PTSD symptoms, and specifically numbing and re-experiencing symptoms, experienced by patients and caregivers during neuro-ICU admission was predictive of worse 3-month QoL. Continued study is needed to identify treatment targets for PTSD and QoL in this population.

Can a Dyadic Resiliency Program Improve Quality of Life in Cognitively Intact Dyads of Neuro-ICU Survivors and Informal Caregivers? Results from a Pilot RCT.

BACKGROUND: Neuro-ICU hospitalization for an acute neurological illness is often traumatic and associated with heightened emotional distress and reduced quality of life (QoL) for both survivors and their informal caregivers (i.e., family and friends providing unpaid care). In a pilot study, we previously showed that a dyadic (survivor and caregiver together) resiliency intervention (Recovering Together [RT]) was feasible and associated with sustained improvement in emotional distress when compared with an attention placebo educational control. Here we report on changes in secondary outcomes assessing QoL. METHODS: Survivors (n = 58) and informal caregivers (n = 58) completed assessments at bedside and were randomly assigned to participate together as a dyad in the RT or control intervention (both 6 weeks, two in-person sessions at bedside and four sessions via live video post discharge). We measured QoL domain scores (physical health, psychological, social relations, and environmental), general QoL, and QoL satisfaction using the World Health Organization Quality of Life Abbreviated Instrument at baseline, post treatment, and 3 months' follow-up. We conducted mixed model analyses of variance with linear contrasts to estimate (1) within-group changes in QoL from baseline to post treatment and from post treatment to 3 months' follow-up and (2) between-group differences in changes in QoL from baseline to post treatment and from post treatment to 3 months' follow-up. RESULTS: We found significant within-group improvements from baseline to post treatment among RT survivors for physical health QoL (mean difference 1.73; 95% confidence interval [CI] 0.39-3.06; p = 0.012), environmental QoL (mean difference 1.29; 95% CI 0.21-2.36; p = 0.020), general QoL (mean difference 0.55; 95% CI 0.13-0.973; p = 0.011), and QoL satisfaction (mean difference 0.87; 95% CI 0.36-1.37; p = 0.001), and those improvements sustained through the 3-month follow-up. We found no significant between-group improvements for survivors or caregivers from baseline to post treatment or from post treatment to 3 months' follow-up for any QoL variables (i.e., domains, general QoL, and QoL satisfaction together). CONCLUSIONS: In this pilot study, we found improved QoL among survivors, but not in caregivers, who received RT and improvements sustained over time. These RT-related improvements were not significantly greater than those observed in the control. Results support a fully powered randomized controlled trial to allow for a definitive evaluation of RT-related effects among dyads of survivors of acute brain injury and their caregivers.

Baseline Resilience and Posttraumatic Symptoms in Dyads of Neurocritical Patients and Their Informal Caregivers: A Prospective Dyadic Analysis.

BACKGROUND: Admission to a neuroscience intensive care unit (Neuro-ICU) is sudden and often traumatic for both patients and their informal caregivers. No prior studies have assessed prospectively risk and resiliency factors for chronic posttraumatic symptoms, as well as the potential interdependence between patients' and caregivers' symptoms over time. OBJECTIVE: To analyze the impact of baseline resiliency factors on symptoms of posttraumatic stress (PTS) longitudinally in dyads of patients admitted to the Neuro-ICU and their primary family caregivers. METHODS: We recruited dyads (M = 108) of patients admitted to the Neuro-ICU (total N = 102) and their family caregivers (total N = 103). Dyads completed self-report assessments of PTS and resiliency factors (mindfulness and coping) at baseline in the Neuro-ICU. PTS was measured again at 3- and 6-month follow-up. RESULTS: Clinically significant PTS symptoms were high at baseline in both patients (20%) and caregivers (16%) and remained high through 6 months (25% in patients; 14% in caregivers). Actor-partner interdependence modeling demonstrated that severity of PTS symptoms was predictive of PTS symptoms at subsequent time points (P < 0.001). High baseline mindfulness and coping predicted less severe PTS symptoms in patients and caregivers (P < 0.001) at all time points. Own degree of PTS symptoms at 3 months predicted worse PTS symptoms in one's partner at 6 months, for both patients and caregivers (P = 0.02). CONCLUSIONS: Findings highlight the need to prioritize assessment and treatment of PTS in Neuro-ICU patients and their informal caregivers through a dyadic approach.

The Impact of Resilience Factors and Anxiety During Hospital Admission on Longitudinal Anxiety Among Dyads of Neurocritical Care Patients Without Major Cognitive Impairment and Their Family Caregivers.

BACKGROUND/OBJECTIVE: Anxiety is common in patients experiencing neurocritical illness and their family caregivers. Resilience factors like mindfulness and coping skills may be protective against symptoms of emotional distress, including anxiety. Less is known about the interplay of anxiety symptoms and resilience factors between patients and caregivers. The purpose of this study is to examine the trajectory of anxiety symptoms among dyads of neurocritical care patients without major cognitive impairment and their family caregivers and to elucidate the relationship between resiliency (e.g., mindfulness and coping) and anxiety in these dyads. METHODS: Prospective, longitudinal study of adults admitted to the neurological intensive care unit (Neuro-ICU) and their caregivers. Dyads of patients (N = 102) and family caregivers (N = 103) completed self-report measures of mindfulness (Cognitive Affective Mindfulness Scale-Revised) and coping (Measure of Current Status-Part A) during Neuro-ICU hospitalization and anxiety symptoms (anxiety subscale of the Hospital Anxiety and Depression Scale) during hospitalization and at 3- and 6-month follow-up. We used actor-partner interdependence modeling to predict the effect of one's own baseline characteristics on one's own and one's partner's future anxiety symptoms. RESULTS: Rates of clinically significant anxiety symptoms were 40% for patients and 42% for caregivers at baseline. Of these, 20% of patients and 23% of caregivers showed moderate and severe symptoms. Approximately, one-third of patients and caregivers reported clinically significant anxiety symptoms at 3- and 6-month follow-ups, with more than 20% endorsing moderate or severe symptoms. Patients' own baseline mindfulness, coping, and anxiety symptoms were associated with lower anxiety symptoms at all time points (ps < 0.001)-this was also true for caregivers. For both patients and caregivers, one's own baseline mindfulness predicted their partner's anxiety symptoms 3 months later (p = 0.008), but not at 6-month follow-up. CONCLUSIONS: Anxiety symptoms in Neuro-ICU patient-caregiver dyads are high through 6 months following admission. Mindfulness is interdependent and protective against anxiety in dyads at 3-month but not 6-month follow-up. Early, dyad-based interventions may prevent the development of chronic anxiety in patients without major cognitive impairment and caregivers.

Building Resiliency in Dyads of Patients Admitted to the Neuroscience Intensive Care Unit and Their Family Caregivers: Lessons Learned From William and Laura.

Sustaining a stroke, regardless of its severity, is a life-changing and often traumatizing event that can lead to chronic depression, anxiety, and posttraumatic stress in both survivors and their family caregivers. Psychosocial interventions for emotional distress after stroke are limited, have emphasized psychoeducation rather than skills, treatment of chronic emotional distress rather than prevention, and have targeted either the patient or their caregiver without accounting for the context of their interpersonal relationship. Here we discuss "Recovering Together," a novel program for dyads of patients with stroke and their family caregivers aimed at preventing chronic emotional distress by using cognitive behavioral principles to teach resiliency and interpersonal communication skills beginning during hospitalization in a neuroscience intensive care unit and continuing after discharge via telehealth. We illustrate the case of a pilot dyad enrolled in the Recovering Together program, to showcase how patients and caregivers can engage with and benefit from it. This dyad's experience suggests that Recovering Together is credible, feasible, and useful. The potential dyadic benefit of this intervention lies not only in providing the opportunity to optimize recovery and prevent long-term emotional distress, but also in creating the space to come together as a pair and make meaning from critical illness.

Medical Treatment Failure for Symptomatic Vasospasm After Subarachnoid Hemorrhage Threatens Long-Term Outcome.

Background and Purpose- Symptomatic vasospasm is a common cause of morbidity and mortality after subarachnoid hemorrhage. We sought to identify predictors and the long-term impact of treatment failure with hypertensive therapy for symptomatic vasospasm. Methods- We performed a retrospective analysis of 1520 subarachnoid hemorrhage patients prospectively enrolled in the Columbia University SAH Outcomes Project between August 1996 and August 2012. One hundred ninety-eight symptomatic vasospasm patients were treated with vasopressors to raise arterial blood pressure, with and without volume expansion. Treatment response, defined as complete or near-complete resolution of the initial neurological deficit, was adjudicated in weekly meetings of the study team based on serial clinical examination after hypertensive treatment. Outcome was evaluated at 1 year with the modified Rankin Scale. Results- Twenty-one percent of the 198 patients who received hypertensive therapy did not respond to treatment. Treatment failure was associated with an increased risk of death or severe disability at 1 year (modified Rankin Scale score of 4-6; 62% versus 25%; P<0.001). Failure of medical therapy was also associated with an admission troponin I level >0.3 µg/L (64% versus 28%; P=0.001), aneurysm coiling (43% versus 20%; P=0.004), and involvement of >1 symptomatic vascular territory at onset (39% versus 22%; P=0.02). In multivariable analysis, treatment failure was independently associated only with troponin I elevation (adjusted odds ratio, 4.30; 95% CI, 1.69-11.09; P=0.002). Conclusions- Failure to respond to induced hypertension for symptomatic vasospasm threatens 1-year outcome. Subarachnoid hemorrhage patients with symptomatic vasospasm who have elevated initial troponin I levels, indicative of neurogenic cardiac injury, are at twice the risk of medical treatment failure. Expedited endovascular therapy should be considered in these patients.

LATERAL BRANCHING OXIDOREDUCTASE acts in the final stages of strigolactone biosynthesis in Arabidopsis.

Strigolactones are a group of plant compounds of diverse but related chemical structures. They have similar bioactivity across a broad range of plant species, act to optimize plant growth and development, and promote soil microbe interactions. Carlactone, a common precursor to strigolactones, is produced by conserved enzymes found in a number of diverse species. Versions of the MORE AXILLARY GROWTH1 (MAX1) cytochrome P450 from rice and Arabidopsis thaliana make specific subsets of strigolactones from carlactone. However, the diversity of natural strigolactones suggests that additional enzymes are involved and remain to be discovered. Here, we use an innovative method that has revealed a missing enzyme involved in strigolactone metabolism. By using a transcriptomics approach involving a range of treatments that modify strigolactone biosynthesis gene expression coupled with reverse genetics, we identified LATERAL BRANCHING OXIDOREDUCTASE (LBO), a gene encoding an oxidoreductase-like enzyme of the 2-oxoglutarate and Fe(II)-dependent dioxygenase superfamily. Arabidopsis lbo mutants exhibited increased shoot branching, but the lbo mutation did not enhance the max mutant phenotype. Grafting indicated that LBO is required for a graft-transmissible signal that, in turn, requires a product of MAX1. Mutant lbo backgrounds showed reduced responses to carlactone, the substrate of MAX1, and methyl carlactonoate (MeCLA), a product downstream of MAX1. Furthermore, lbo mutants contained increased amounts of these compounds, and the LBO protein specifically converts MeCLA to an unidentified strigolactone-like compound. Thus, LBO function may be important in the later steps of strigolactone biosynthesis to inhibit shoot branching in Arabidopsis and other seed plants.

Bedside quantitative electroencephalography improves assessment of consciousness in comatose subarachnoid hemorrhage patients.

OBJECTIVE: Accurate behavioral assessments of consciousness carry tremendous significance in guiding management, but are extremely challenging in acutely brain-injured patients. We evaluated whether electroencephalography (EEG) and multimodality monitoring parameters may facilitate assessment of consciousness in patients with subarachnoid hemorrhage. METHODS: A retrospective analysis was performed of 83 consecutively treated adults with subarachnoid hemorrhage. All patients were initially comatose and had invasive brain monitoring placed. Behavioral assessments were performed during daily interruption of sedation and categorized into 3 groups based on their best examination as (1) comatose, (2) arousable (eye opening or attending toward a stimulus), and (3) aware (command following). EEG features included spectral power and complexity measures. Comparisons were made using bootstrapping methods and partial least squares regression. RESULTS: We identified 389 artifact-free EEG clips following behavioral assessments. Increasing central gamma, posterior alpha, and diffuse theta-delta oscillations differentiated patients who were arousable from those in coma. Command following was characterized by a further increase in central gamma and posterior alpha, as well as an increase in alpha permutation entropy. These EEG features together with basic neurological examinations (eg, pupillary light reflex) contributed heavily to a linear model predicting behavioral state, whereas brain physiology measures (eg, brain oxygenation), structural injury, and clinical course added less. INTERPRETATION: EEG measures of behavioral states provide distinctive signatures that complement behavioral assessments of patients with subarachnoid hemorrhage shortly after the injury. Our data support the hypothesis that impaired connectivity of cortex with both central thalamus and basal forebrain underlies decreasing levels of consciousness. Ann Neurol 2016;80:541-553.

"It's Been a Game Changer": Examining Treadmill Desk Use When Working from Home.

Previous research has established the physical and mental benefits of using active workstations like treadmill desks in the workplace, such as reducing sedentary behavior and improving mood. However, treadmill desk use when working at home has not been examined despite significant increases in working from home during the COVID-19 pandemic. Therefore, the objectives of this study were (1) to be the first to describe how treadmill desks are used when working from home and (2) to describe perceived benefits, motivators, and barriers for treadmill desk use when working from home. Twenty participants who worked from home and used a treadmill desk were interviewed between February 2022 and April 2022. Participants reported using their treadmill desks while completing a variety of work and non-work tasks and experienced physical, mental, social, and work-related perceived benefits. Motivators for use included desires to reduce prolonged sitting and be more active, wanting to be healthier and fitter, tracking and reaching goals like daily step counts, feeling good during use, and to overcome increased sedentary behavior due to working from home during the COVID-19 pandemic. Barriers to use included the type of work being done, physical limitations, accessibility issues, social concerns, and mental barriers. Future research should investigate ways to increase treadmill desk use at home by capitalizing on motivating factors and reducing barriers to use.

Baseline resilience and depression symptoms predict trajectory of depression in dyads of patients and their informal caregivers following discharge from the Neuro-ICU.

OBJECTIVE: To explore the impact of resiliency factors on the longitudinal trajectory of depressive symptoms in patients admitted to the Neuroscience Intensive Care Unit (Neuro-ICU) and their family caregivers. MATERIALS AND METHODS: Patients (N = 102) and family caregivers (N = 103) completed self-report assessments of depressive symptoms (depression subscale of the Hospital Anxiety and Depression Scale; HADS-D) and resiliency factors (i.e., mindfulness and coping) during Neuro-ICU hospitalization. The HADS-D was administered again at 3 and 6 months after discharge. The Actor-Partner Interdependence Model (APIM) was used to assess patient-caregiver interdependence. RESULTS: Baseline rates of clinically significant depressive symptoms were high among patients (23%) and caregivers (19%), and remained elevated through 6-months. Higher depressive symptoms predicted higher levels of symptoms at the subsequent timepoint (ps < 0.05). Higher baseline mindfulness and coping were associated with lower levels of depressive symptoms at all timepoints (ps < 0.001). APIM analysis showed that one's own higher baseline mindfulness was associated with concurrent levels of depressive symptoms in a partner (p < 0.05). CONCLUSIONS: Depressive symptoms in Neuro-ICU patient-caregiver dyads are high through 6 months. Mindfulness is protective against depressive symptoms and interdependent between patients and caregivers. Early, dyadic, mindfulness-based interventions may prevent the development of chronic depression in both patients and caregivers.

Feasibility and Efficacy of a Resiliency Intervention for the Prevention of Chronic Emotional Distress Among Survivor-Caregiver Dyads Admitted to the Neuroscience Intensive Care Unit: A Randomized Clinical Trial.

Importance: To our knowledge, there are no evidence-based interventions to prevent chronic emotional distress (ie, depression, anxiety, and posttraumatic stress [PTS]) in critical care survivors and their informal caregivers. Objective: To determine the feasibility and preliminary effect of the novel dyadic resiliency intervention Recovering Together (RT) on reducing symptoms of depression, anxiety, and PTS among hospitalized patients and their informal caregivers. Design, Setting, and Participants: This single-blind, pilot randomized clinical trial of RT vs an educational control was conducted among 58 dyads in which either the survivor or caregiver endorsed clinically significant symptoms of depression, anxiety, or PTS. The study was conducted in the neuroscience intensive care unit at Massachusetts General Hospital. Data were collected from September 2019 to March 2020. Interventions: Both RT and control programs had 6 sessions (2 at bedside and 4 via live video after discharge), and both survivor and caregiver participated together. Main Outcomes and Measures: The primary outcomes were feasibility of recruitment and intervention delivery, credibility, and satisfaction. The secondary outcomes included depression and anxiety (measured by the Hospital Depression and Anxiety Scale), PTS (measured by the PTSD Checklist-Civilian Version), and intervention targets (ie, mindfulness, measured by the Cognitive and Affective Mindfulness Scale-Revised; coping, measured by the Measure of Current Status-Part A; and dyadic interpersonal interactions, measured by the Dyadic Relationship Scale). Main outcomes and targets were assessed at baseline, 6 weeks, and 12 weeks. Results: The 58 dyads were randomized to RT (29 dyads [50.0%]; survivors: mean [SD] age, 49.3 [16.7] years; 9 [31.0%] women; caregivers: mean [SD] age, 52.4 [14.3] years; 22 [75.9%] women) or control (29 dyads [50.0%]; survivors: mean [SD] age, 50.3 [16.4] years; 12 [41.3%] women; caregivers, mean [SD] age, 52.1 [14.9], 17 [58.6%] women). Feasibility (recruitment [76%], randomization [100%], and data collection [83%-100%]), adherence (86%), fidelity (100%; κ = 0.98), satisfaction (RT: 57 of 58 [98%] with scores >6; control: 58 of 58 [100%] with scores >6), credibility (RT: 47 of 58 [81%] with scores >6; control: 46 of 58 [80%] with scores >6), and expectancy (RT: 49 of 58 [85%] with scores >13.5; 51 of 58 [87%] with scores >13.5) exceeded benchmarks set a priori. Participation in RT was associated with statistically and clinically significant improvement between baseline and postintervention in symptoms of depression (among survivors: -4.0 vs -0.6; difference, -3.4; 95% CI, -5.6 to -1.3; P = .002; among caregivers: -3.8 vs 0.6; difference, -4.5; 95% CI, -6.7 to -2.3; P < .001), anxiety (among survivors: -6.0 vs 0.3; difference, -6.3; 95% CI, -8.8 to -3.8; P < .001; among caregivers: -5.0 vs -0.9; difference, -4.1; 95% CI, -6.7 to -1.5, P = .002), and PTS (among survivors: -11.3 vs 1.0; difference, -12.3; 95% CI, -18.1 to -6.5, P < .001; among caregivers, -11.4 vs 5.0; difference, -16.4, 95% CI, -21.8 to -10.9; P < .001). Improvements sustained through the 12-week follow-up visit. We also observed RT-dependent improvement in dyadic interpersonal interactions for survivors (0.2 vs -0.2; difference, 0.4; 95% CI, 0.0 to 0.8; P = .04). Conclusions and Relevance: In this pilot randomized clinical trial, RT was feasible and potentially efficacious in preventing chronic emotional distress in dyads of survivors of the neuroscience intensive care unit and their informal caregivers.

Ultra-early angiographic vasospasm associated with delayed cerebral ischemia and infarction following aneurysmal subarachnoid hemorrhage.

OBJECTIVE The clinical significance of cerebral ultra-early angiographic vasospasm (UEAV), defined as cerebral arterial narrowing within the first 48 hours of aneurysmal subarachnoid hemorrhage (aSAH), remains poorly characterized. The authors sought to determine its frequency, predictors, and impact on functional outcome. METHODS The authors prospectively studied UEAV in a cohort of 1286 consecutively admitted patients with aSAH between August 1996 and June 2013. Admission clinical, radiographic, and acute clinical course information was documented during patient hospitalization. Functional outcome was assessed at 3 months using the modified Rankin Scale. Logistic regression and Cox proportional hazards models were generated to assess predictors of UEAV and its relationship to delayed cerebral ischemia (DCI) and outcome. Multiple imputation methods were used to address data lost to follow-up. RESULTS The cohort incidence rate of UEAV was 4.6%. Multivariable logistic regression analysis revealed that younger age, sentinel bleed, and poor admission clinical grade were significantly associated with UEAV. Patients with UEAV had a 2-fold increased risk of DCI (odds ratio [OR] 2.3, 95% confidence interval [CI] 1.4-3.9, p = 0.002) and cerebral infarction (OR 2.0, 95% CI 1.0-3.9, p = 0.04), after adjusting for known predictors. Excluding patients who experienced sentinel bleeding did not change this effect. Patients with UEAV also had a significantly higher hazard for DCI in a multivariable model. UEAV was not found to be significantly associated with poor functional outcome (OR 0.8, 95% CI 0.4-1.6, p = 0.5). CONCLUSIONS UEAV may be less frequent than has been reported previously. Patients who exhibit UEAV are at higher risk for refractory DCI that results in cerebral infarction. These patients may benefit from earlier monitoring for signs of DCI and more aggressive treatment. Further study is needed to determine the long-term functional significance of UEAV.

Loss of Consciousness at Onset of Subarachnoid Hemorrhage as an Important Marker of Early Brain Injury.

IMPORTANCE: Loss of consciousness (LOC) is a common presenting symptom of subarachnoid hemorrhage (SAH) that is presumed to result from transient intracranial circulatory arrest. OBJECTIVE: To clarify the association between LOC at onset of SAH, complications while in the hospital, and long-term outcome after SAH. DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis was conducted of 1460 consecutively treated patients with spontaneous SAH who were part of a prospective observational cohort study at a large urban academic medical center (the Columbia University SAH Outcomes Project or SHOP). Patients were enrolled between August 6, 1996, and July 23, 2012. Analysis was conducted from December 1, 2013, to February 28, 2015. EXPOSURES: Loss of consciousness at onset was identified by structured interview of the patient and first responders. Patients (80.5%) were observed for up to 1 year to assess functional recovery. MAIN OUTCOMES AND MEASURES: Modified Rankin scale scores were assigned based on telephone or in-person interviews of the patient, family members, or caregivers. Complications while in the hospital were predefined and adjudicated by the study team. RESULTS: Five hundred ninety patients (40.4%) reported LOC at onset of SAH. Loss of consciousness was associated with poor clinical grade, more subarachnoid and intraventricular blood seen on admission computed tomographic scan, and a higher frequency of global cerebral edema (P < .001). Loss of consciousness was also associated with more prehospital tonic-clonic activity (22.7% vs 4.2%; P < .001) and cardiopulmonary arrest (9.7% vs 0.5%, P < .001) vs patients who did not experience LOC. In multivariable analysis, death or severe disability at 12 months was independently associated with LOC after adjusting for established risk factors for poor outcome, including poor admission clinical grade (adjusted odds ratio, 1.94; 95% CI, 1.38-2.72; P < .001). There was no association between LOC at onset and delayed cerebral ischemia or aneurysm rebleeding. CONCLUSIONS AND RELEVANCE: Loss of consciousness at symptom onset is an important manifestation of early brain injury after SAH and a predictor of death or poor functional outcome at 12 months.

Patient-Powered Reporting of Modified Rankin Scale Outcomes Via the Internet.

BACKGROUND AND PURPOSE: The modified Rankin Scale (mRS) is a common and resource-intensive measure of functional outcome in stroke-related conditions. In this observational prospective cohort feasibility study, mRS scores are generated using a patient-powered online survey and compared to scores obtained by structured telephonic interview. MATERIALS AND METHODS: Fifty-one patients with subarachnoid hemorrhage (SAH) or their surrogates responded to an online survey following discharge from the hospital. These responses were used to generate an mRS score and then compared to blinded telephonic assessments by trained personnel. A weighted kappa (Kw) with confidence intervals (CIs) was calculated. RESULTS: The Kw between the patient/surrogate and the trained personnel scores was 0.85 (95% CI, 0.74-0.95, P < .001). CONCLUSION: This study provides first evidence that patient/surrogate survey responses may be an efficient and reliable alternative to generate mRS scores compared to trained personnel after SAH.

Predictors of Poor Quality of Life 1 Year After Subarachnoid Hemorrhage.

BACKGROUND: Risk factors for poor quality of life (QOL) after subarachnoid hemorrhage (SAH) remain poorly described. OBJECTIVE: To identify the frequency and predictors of poor QOL 1 year after SAH. METHODS: We studied 1-year QOL in a prospectively collected cohort of 1181 consecutively admitted SAH survivors between July 1996 and May 2013. Patient clinical, radiographic, surgical, and acute clinical course information was recorded. Reduced QOL (overall, physical, and psychosocial) at 1 year was assessed with the Sickness Impact Profile and defined as 2 SD below population-based normative Sickness Impact Profile values. Logistic regression leveraging multiple imputation to handle missing data was used to evaluate reduced QOL. RESULTS: Poor overall QOL was observed in 35% of patients. Multivariable analysis revealed that nonwhite ethnicity, high school education or less, history of depression, poor clinical grade (Hunt-Hess Grade ≥3), and delayed infarction were predictors of poor overall and psychosocial QOL. Poor physical QOL was additionally associated with older age, hydrocephalus, pneumonia, and sepsis. At 1 year, patients with poor QOL had increased difficulty concentrating, cognitive dysfunction, depression, and reduced activities of daily living. More than 91% of patients with poor QOL failed to fully return to work. These patients frequently received physical rehabilitation, but few received cognitive rehabilitation or emotional-behavioral support. CONCLUSION: Reduced QOL affects as many as one-third of SAH survivors 1 year after SAH. Delayed infarction is the most important in-hospital modifiable factor that affects QOL. Increased attention to cognitive and emotional difficulties after hospital discharge may help patients achieve greater QOL.

Seizure burden in subarachnoid hemorrhage associated with functional and cognitive outcome.

OBJECTIVE: To assess the relationship between seizure burden on continuous EEG (cEEG) and functional as well as cognitive outcome 3 months after subarachnoid hemorrhage (SAH). METHODS: The study included all consecutive patients with a spontaneous SAH admitted to the Columbia University Medical Center Neurological Intensive Care Unit and monitored with cEEG between 1996 and 2013. Seizure burden was defined as the duration, in hours, of seizures on cEEG. Cognitive outcomes were measured with the Telephone Interview for Cognitive Status (TICS, ranging from 0 to 51, indicating poor to good global mental status). RESULTS: Overall, 402 patients with SAH were included with a median age of 58 years (interquartile range [IQR] 46-68 years). The median duration of cEEG monitoring was 96 hours (IQR 48-155 hours). Seizures were recorded in 50 patients (12%), in whom the median seizure burden was 6 hours (IQR 1-13 hours). At 3 months, in multivariate analysis, seizure burden was associated with unfavorable functional and cognitive outcome. Every hour of seizure on cEEG was associated with an odds ratio of 1.10 (95% confidence interval [CI] 1.01-1.21, p = 0.04) to 3-month disability and mortality, and the TICS-score decreased, on average, by 0.16 points (adjusted coefficient -0.19, 95% CI -0.33 to -0.05, p = 0.01). CONCLUSION: In this study, after adjusting for established predictors, seizure burden was associated with functional outcome and cognitive impairment 3 months after SAH.

Intraventricular hemorrhage expansion in patients with spontaneous intracerebral hemorrhage.

OBJECTIVE: To evaluate whether delayed appearance of intraventricular hemorrhage (dIVH) represents an independent entity from intraventricular hemorrhage (IVH) present on admission CT or is primarily related to the time interval between symptom onset and admission CT. METHODS: A total of 282 spontaneous intracerebral hemorrhage (ICH) patients, admitted February 2009-March 2014 to the neurological intensive care unit of a tertiary care university hospital, were prospectively enrolled in the ICH Outcomes Project. Multivariate logistic regression was used to determine associations with acute mortality and functional long-term outcome (modified Rankin Scale). RESULTS: A cohort of 282 ICH patients was retrospectively studied: 151 (53.5%) had intraventricular hemorrhage on initial CT scan (iIVH). Of the remaining 131 patients, 19 (14.5%) developed IVH after the initial CT scan (dIVH). The median times from symptom onset to admission CT were 1.1, 6.0, and 7.4 hours for the dIVH, iIVH, and no IVH groups (Mann-Whitney U test, dIVH vs iIVH, p < 0.001) and median time from onset to dIVH detection was 7.2 hours. The increase in ICH volume following hospital admission was larger in dIVH than in iIVH and no IVH patients (mean 17.6, 0.2, and 0.4 mL). After controlling for components of the ICH score and hematoma expansion, presence of IVH on initial CT was associated with discharge mortality and poor outcome at 3, 6, and 12 months, but dIVH was not associated with any of the outcome measures. CONCLUSIONS: In ICH patients, associated IVH on admission imaging is commonly encountered and is associated with poor long-term outcome. In contrast, dIVH on subsequent scans is far less common and does not appear to portend worse outcome.
