Post-Intensive Care Syndrome in Neurocritical Care Patients.

Post-intensive care syndrome (PICS) refers to unintended consequences of critical care that manifest as new or worsening impairments in physical functioning, cognitive ability, or mental health. As intensive care unit (ICU) survival continues to improve, PICS is becoming increasingly recognized as a public health problem. Studies that focus on PICS have typically excluded patients with acute brain injuries and chronic neurodegenerative problems. However, patients who require neurocritical care undoubtedly suffer from impairments that overlap substantially with those encompassed by PICS. A major challenge is to distinguish between impairments related to brain injury and those that occur as a consequence of critical care. The general principles for the prevention and management of PICS and multidomain impairments in patients with moderate and severe neurological injuries are similar including the ICU liberation bundle, multidisciplinary team-based care throughout the continuum of care, and increasing awareness regarding the challenges of critical care survivorship among patients, families, and multidisciplinary team members. An extension of this concept, PICS-Family (PICS-F) refers to the mental health consequences of the intensive care experience for families and loved ones of ICU survivors. A dyadic approach to ICU survivorship with an emphasis on recognizing families and caregivers that may be at risk of developing PICS-F after neurocritical care illness can help improve outcomes for ICU survivors. In this review, we will summarize our current understanding of PICS and PICS-F, emerging literature on PICS in severe acute brain injury, strategies for preventing and treating PICS, and share our recommendations for future directions.

Patient-centered mild traumatic brain injury interventions in the emergency department.

INTRODUCTION: Traumatic brain injury (TBI) results in 2.5 million emergency department (ED) visits per year in the US, with mild traumatic brain injury (mTBI) accounting for 90% of cases. There is considerable evidence that many experience chronic symptoms months to years later. This population is rarely represented in interventional studies. Management of adult mTBI in the ED has remained unchanged, without consensus of therapeutic options. The aim of this review was to synthesize existing literature of patient-centered ED treatments for adults who sustain an mTBI, and to identify practices that may offer promise. METHODS: A systematic review was conducted using the PubMed and Cochrane databases, while following PRISMA guidelines. Studies describing pediatric patients, moderate to severe TBI, or interventions outside the ED were excluded. Two reviewers independently performed title and abstract screening. A third blinded reviewer resolved discrepancies. The Mixed Methods Appraisal Tool (MMAT) was employed to assess the methodological quality of the studies. RESULTS: Our search strategy generated 1002 unique titles. 95 articles were selected for full-text screening. The 26 articles chosen for full analysis were grouped into one of the following intervention categories: (1) predictive models for Post-Concussion Syndrome (PCS), (2) discharge instructions, (3) pharmaceutical treatment, (4) clinical protocols, and (5) functional assessment. Studies that implemented a predictive PCS model successfully identified patients at highest risk for PCS. Trials implementing discharge related interventions found the use of video discharge instructions, encouragement of daily light exercise or bed rest, and text messaging did not significantly reduce mTBI symptoms. The use of electronic clinical practice guidelines (eCPG) and longer leaves of absence from work following injury reduced symptoms. Ondansetron was shown to reduce nausea in mTBI patients. Studies implementing ED Observation Units found significant declines in inpatient admissions and length of hospital stay. The use of tablet-based tasks was found to be superior to many standard cognitive assessments. CONCLUSION: Validated instruments are available to aid clinicians in identifying patients at risk for PCS or serious cognitive impairment. EDOU management and evidence-based modifications to discharge instructions may improve mTBI outcomes. Additional research is needed to establish the therapeutic value of medications and lifestyle changes for the treatment of mTBI in the ED.

Iterative Development of the Caregiver Wellness After Traumatic Brain Injury Program (CG-Well).

OBJECTIVES: (1) To iteratively design a web/phone-based intervention to support caregivers of adults acutely following traumatic brain injury (TBI), Caregiver Wellness (CG-Well), and (2) to obtain qualitative and quantitative feedback on CG-Well from experts and caregivers to refine the intervention. SETTING: A level I trauma and tertiary medical center. PARTICIPANTS: Convenience sample of a total of 19 caregivers and 25 experts. DESIGN: Multistep prospective study with iterative changes to CG-Well: (1) developed intervention content based on qualitative feedback from a prior study and literature review; (2) obtained qualitative feedback from 10 experts; (3) refined content using a modified Delphi approach involving 4 caregivers and 6 experts followed by qualitative interviews with 9 caregivers; (4) designed CG-Well website and videos; and (5) obtained feedback on program acceptability, appropriateness, and feasibility from 6 caregivers and 9 experts. INTERVENTIONS: CG-Well included content on TBI, self-care and support, and skill-building strategies delivered through a website and telephone calls. MAIN OUTCOME MEASURES: Qualitative data were analyzed using content analysis. Caregivers and experts completed Likert-type scales to rate module relevance, clarity, accuracy, utility and website acceptability, appropriateness, and feasibility (1 = strongly disagree to 5 = strongly agree). Means and standard deviations (SD) characterized ratings. RESULTS: Qualitative findings were instrumental in designing and refining CG-Well. Ratings were positive for modules (means and SD for relevant [4.9, 0.33], clear [4.6, 0.53], accurate [4.9, 0.33], and useful [5, 0]) and the website (means and SD for acceptable [4.8, 0.36], appropriate [4.8, 0.35], and feasible [4.8, 0.36]). CONCLUSIONS: The iterative design process for CG-Well resulted in a highly acceptable program. An early-stage randomized controlled trial is underway to estimate treatment effects for a future well-powered clinical trial.

Antithrombotic regimens and need for critical care interventions among patients with subdural hematomas.

BACKGROUND: Antithrombotic-associated subdural hematomas (SDHs) are increasingly common, and the possibility of clinical deterioration in otherwise stable antithrombotic-associated SDH patients may prompt unnecessary admissions to intensive care units. It is unknown whether all antithrombotic regimens are equally associated with the need for critical care interventions. We sought to compare the frequency of critical care interventions and poor functional outcomes among three cohorts of noncomatose SDH patients: patients on no antithrombotics, patients on anticoagulants, and patients on antiplatelets alone. METHODS: We performed a retrospective cohort study on all noncomatose SDH patients (Glasgow Coma Scale > 12) presenting to an academic health system in 2018. The three groups of patients were compared in terms of clinical course and functional outcome. Multivariable logistic regression was used to determine predictors of need for critical care interventions and poor functional outcome at hospital discharge. RESULTS: There were 281 eligible patients presenting with SDHs in 2018, with 126 (45%) patients on no antithrombotics, 106 (38%) patients on antiplatelet medications alone, and 49 (17%) patients on anticoagulants. Significant predictors of critical care interventions were coagulopathy (OR 5.1, P < 0.001), presence of contusions (OR 3, P = 0.007), midline shift (OR 3.4, P = 0.002), and maximum SDH thickness (OR 2.4, P = 0.002). Significant predictors of poor functional outcome were age (OR 1.8, P < 0.001), admission Glasgow Coma Scale score (OR 0.3, P < 0.001), dementia history (OR 4.2, P = 0.001), and coagulopathy (OR 3.5, P = 0.02). Isolated antiplatelet use was not associated with either critical care interventions or functional outcome. CONCLUSION: Isolated antiplatelet use is not a significant predictor of need for critical care interventions or poor functional outcome among SDH patients and should not be used as a criterion for triage to the intensive care unit.

Management of the mild traumatic brain injured patient using a multidisciplinary observation unit protocol.

OBJECTIVES: We developed an ED based multidisciplinary observation unit (OU) protocol for patients with mild traumatic brain injury (mTBI). We describe the cohort of patients who were placed in the ED OU and we evaluated if changes to our inclusion and exclusion criteria should be made. METHODS: We conducted a retrospective cohort study to evaluate subjects who were admitted to the mTBI observation protocol. We included adults within 24 h of sustaining an mTBI with a Glasgow Coma Scale (GCS) of 14 or 15 who had pre-specified head CT findings, and did not meet exclusion criteria. Predictors of need for hospital admission after completing the OU protocol were determined using multivariable logistic regression analysis. RESULTS: The mean age was 49 (SD 23), 58 (33%) were female, and 136 (78%) were Caucasian. No subjects discharged home required a surgical intervention or ICU admission, and there were no deaths in discharged or admitted subjects. 28 subjects (16%) were admitted to the hospital following their OU stay. Subjects admitted were older (mean age: 56 vs. 48, p = 0.1) and had a higher proportion of traumatic bleeds on head CT (85% vs. 76%, p = 0.3). In multivariable logistic regression, GCS of 15 (aOR 4.24), African-American race (aOR 5.84), and no comorbid cardiac disease predicted discharge home after the observation protocol (aOR 0.28). CONCLUSIONS: A period of observation for a pre-defined cohort of patients with mTBI provided a triage plan that could allow appropriate patient management without requiring admission in the majority of subjects.

Use of the Sports Concussion Assessment Tool 3 in Emergency Department Patients With Psychiatric Disease.

OBJECTIVE: The Sports Concussion Assessment Tool 3 (SCAT3) Symptom Evaluation (SE) is used in the emergency department (ED). This study aimed to examine the effects of psychiatric history on the SCAT3 SE symptom severity score (SSS). SETTING: Three US EDs. PARTICIPANTS: A total of 272 ED patients with suspected concussion. DESIGN: Prospective, nonrandomized, nonblinded study. The SCAT3 SE SSS, demographic data, medical information, and self-reported psychiatric history were obtained from patients by clinical research staff when they presented to the ED seeking standard clinical care. Concussion diagnoses were determined following a comprehensive assessment by an ED physician trained in managing concussions and adjudicated by supervising physicians. MAIN MEASURES: The primary outcome measure was SSS. The association between SSS, self-reported psychiatric disease, and concussion diagnosis was analyzed using multivariable linear regression. RESULTS: 68.4% of subjects were diagnosed with a concussion. After controlling for age, sex, race, history of previous concussion, and interval from injury to ED presentation, self-reported psychiatric history (adjusted regression coefficient (ßa): 16.9; confidence interval [CI]: 10.1, 23.6), and concussion diagnosis (ßa: 21.7; CI: 14.2, 29.2) were both independently associated with a significant increase in SSS. Subjects with a history of concussion had a significantly higher SSS (ßa: 9.1; CI: 1.8, 16.5). Interval from injury to ED presentation was also associated with a significant increase in SSS (ßa: 1.6 per 6-hour increase; CI: 0.4, 2.8). CONCLUSION: Our findings demonstrate that a history of preexisting psychiatric disease, as self-reported by patients with a suspected concussion treated in the ED, is independently associated with significantly higher scores on the SCAT3 SE. This suggests that a history of psychiatric illness may need to be accounted for when the SCAT3 SE is used in the ED for the assessment of concussion.

Effect of COVID-19 on Emergent Stroke Care: A Regional Experience.

BACKGROUND AND PURPOSE: Anecdotal evidence suggests that the coronavirus disease 2019 (COVID-19) pandemic mitigation efforts may inadvertently discourage patients from seeking treatment for stroke with resultant increased morbidity and mortality. Analysis of regional data, while hospital capacities for acute stroke care remained fully available, offers an opportunity to assess this. We report regional Stroke Team acute activations and reperfusion treatments during COVID-19 mitigation activities. METHODS: Using case log data prospectively collected by a Stroke Team exclusively serving ≈2 million inhabitants and 30 healthcare facilities, we retrospectively reviewed volumes of consultations and reperfusion treatments for acute ischemic stroke. We compared volumes before and after announcements of COVID-19 mitigation measures and the prior calendar year. RESULTS: Compared with the 10 weeks prior, stroke consultations declined by 39% (95% CI, 32%-46%) in the 5 weeks after announcement of statewide school and restaurant closures in Ohio, Kentucky, and Indiana. Results compared with the prior year and time trend analyses were consistent. Reperfusion treatments also appeared to decline by 31% (95% CI, 3%-51%), and specifically thrombolysis by 33% (95% CI, 4%-55%), but this finding had less precision. CONCLUSIONS: Upon the announcement of measures to mitigate COVID-19, regional acute stroke consultations declined significantly. Reperfusion treatment rates, particularly thrombolysis, also appeared to decline qualitatively, and this finding requires further study. Urgent public education is necessary to mitigate a possible crisis of avoiding essential emergency care due to COVID-19.

Implementation of a Neurotrauma Hotline for post-hospital continuity of care.

BACKGROUND: There are 4.8 million emergency department (ED) visits for traumatic brain injury (TBI) annually in the United States. Many of these patients do not receive educational information or follow-up care. AIMS OF THE STUDY: Our institution implemented a Neurotrauma Hotline for TBI patients. This study describes our implementation and utilization of a Neurotrauma Hotline at a Level I trauma center. METHODS: Callers and outcomes of calls to the hotline over a 12-month period were analyzed. Correlation analysis was done to assess relationship between hotline calls and TBI clinic volumes. RESULTS: There were 1205 calls to the hotline. Calls were most commonly from internal providers or patients, with 338 repeat callers. The call reason was frequently an appointment (36.8%) or advice (32.1%). There were 334 TBI clinic visits, and however, there was no statistically significant correlation between number of hotline calls and number of clinic visits (r = .417; P = .177). CONCLUSIONS: There was widespread utilization of our hotline. Other institutions wishing to adopt similar practices can expect that the majority of calls will be for appointment scheduling or clinical advice. Further work is needed to determine whether implementation of a Neurotrauma Hotline improves resource utilization and patient outcomes.

The Experience of Caregivers Following a Moderate to Severe Traumatic Brain Injury Requiring ICU Admission.

OBJECTIVES: Survivors of moderate and severe traumatic brain injury (TBI) require substantial care, much of which is ultimately provided by friends and family. We sought to describe the unmet needs of informal caregivers. DESIGN: Qualitative, semistructured interviews with informal caregivers of moderate and severe TBI survivors were conducted 72 hours, 1 month, 3 months, and 6 months after injury. SETTING: Intensive care unit of a level 1 trauma center. PARTICIPANTS: Informal caregivers were friends or family who planned to provide care for the patient. Patients were 18 years or older with a moderate to severe TBI, and not expected to imminently die of their injuries. MEASUREMENTS AND MAIN RESULTS: Eighteen patient-caregiver dyads were enrolled. Fifty-three interviews with caregivers were completed and analyzed over the course of 6 months. Three themes were identified in the qualitative analysis: caregiver burden, caregiver health-related quality of life, and caregiver needs for information and support. CONCLUSIONS: This study provides new information about the experience of informal caregivers during the 6 months after their friend or family member survived a moderate to severe TBI. Interventions to promote caregiving may be a substantial opportunity to improve patient-centered outcomes following TBI.

Rehabilitation Practices in Patients With Moderate and Severe Traumatic Brain Injury.

OBJECTIVE: To characterize the indications, timing, barriers, and perceived value of rehabilitation currently provided for individuals with moderate or severe traumatic brain injury (TBI) admitted to the intensive care unit (ICU) based on the perspectives of providers who work in the ICU setting. PARTICIPANTS: Members (n = 66) of the Neurocritical Care Society and the American Congress of Rehabilitation Medicine. DESIGN: An anonymous electronic survey of the timing of rehabilitation for patients with TBI in the ICU. MAIN MEASURES: Questions asked about type and timing of rehabilitation in the ICU, extent of family involvement, participation of physiatrists in patient care, and barriers to early rehabilitation. RESULTS: Sixty-six respondents who reported caring for patients with TBI in the ICU completed the survey; 98% recommended rehabilitative care while patients were in the ICU. Common reasons to wait for the initiation of physical therapy and occupational therapy were normalization of intracranial pressure (86% and 89%) and hemodynamic stability (66% and 69%). CONCLUSIONS: The majority of providers caring for patients with TBI in the ICU support rehabilitation efforts, typically after a patient is extubated, intracranial pressure has normalized, and the patient is hemodynamically stable. Our findings describe current practice; future studies can be designed to determine optimal timing, intensity, and patient selection for early rehabilitation.

The Effect of Antidepressants on Depression After Traumatic Brain Injury: A Meta-analysis.

OBJECTIVE: Following traumatic brain injury (TBI), depressive symptoms are common and may influence recovery. We performed a meta-analysis to estimate the benefit of antidepressants following TBI and compare the estimated effects between antidepressants and placebo. PARTICIPANTS: Multiple databases were searched to find prospective pharmacological treatment studies of major depressive disorder (MDD) in adults following TBI. MAIN MEASURES: Effect sizes for antidepressant medications in patients with TBI were calculated for within-subjects designs that examined change from baseline after receiving medical treatment and treatment/placebo designs that examined the differences between the antidepressants and placebo groups. DESIGN: A random-effects model was used for both analyses. RESULTS: Of 1028 titles screened, 11 were included. Pooled estimates showed nonsignificant difference in reduction of depression scores between medications and placebo (standardized mean difference of 5 trials = -0.3; 95% CI, -0.6 to 0.0; I = 17%), and a significant reduction in depression scores for individuals after pharmacotherapy (mean change = -11.2; 95% CI, -14.7 to -7.6 on the Hamilton Depression Scale; I = 87%). CONCLUSIONS: This meta-analysis found no significant benefit of antidepressant over placebo in the treatment of MDD following TBI. Pooled estimates showed a high degree of bias and heterogeneity. Prospective studies on the impact of antidepressants in well-defined cohorts of TBI patients are warranted.

A Comparison of Satisfaction With Life and the Glasgow Outcome Scale-Extended After Traumatic Brain Injury: An Analysis of the TRACK-TBI Pilot Study.

OBJECTIVE: To evaluate the relationship between satisfaction with life (SWL) and functional outcome after traumatic brain injury (TBI). SETTING AND PARTICIPANTS: The Transforming Research and Clinical Knowledge in Traumatic Brain Injury Pilot study (TRACK-TBI Pilot) enrolled patients at 3 US Level I trauma centers within 24 hours of TBI. DESIGN: Patients were grouped by outcome measure concordance (good-recovery/good-satisfaction, impaired-recovery/impaired-satisfaction) and discordance (good-recovery/impaired-satisfaction, impaired-recovery/good-satisfaction). Logistic regression was utilized to determine predictors of discordance. MAIN MEASURES: Functional outcome: Glasgow Outcome Scale-Extended (GOSE); SWL: Satisfaction with Life Scale (SWLS). RESULTS: Of the 586 enrolled subjects, 298 had completed both outcome measures at 6-month follow-up; the correlation between GOSE and SWLS was 0.380. Patients with impaired-recovery (GOSE < 7)/impaired-satisfaction (SWLS < 20) were more likely to have mild TBI (83% vs 62%, P = .012), baseline depression (42% vs 15%, P < .0001), and 6-month depression (59% vs 21%, P < .0001) when compared with patients with impaired-recovery/good-satisfaction. Patients with good-recovery/impaired-satisfaction were more likely to have baseline depression (31% vs 13%, P < .0001) and 6-month depression (33% vs 6%, P < .0001) compared with good-recovery/good-satisfaction. CONCLUSION: Correlation between SWL and functional outcome was not strong, and depression may modulate the association. Future research should account for functional, mental health, and patient-centered outcomes when assessing TBI recovery.

Systematic Review of Caregiver and Dyad Interventions After Adult Traumatic Brain Injury.

OBJECTIVE: To describe and synthesize the literature on adult traumatic brain injury (TBI) family caregiver and dyad intervention. TBI is a common injury that has a significant long-term impact, and is sometimes even characterized as a chronic condition. Informal (ie, unpaid) family caregivers of adults with TBI experience high rates of burnout, depression, fatigue, anxiety, lower subjective well-being, and poorer levels of physical health compared to noncaregivers. This study addresses the critical gap in the understanding of interventions designed to address the impact of TBI on adult patients and their family caregivers. DATA SOURCES: PubMed and MEDLINE. STUDY SELECTION: Studies selected for review had to be written in English and be quasi-experimental or experimental in design, report on TBI caregivers, survivors with heavy involvement of caregivers, or caregiver dyads, involve moderate and severe TBI, and describe an intervention implemented during some portion of the TBI care continuum. DATA EXTRACTION: The search identified 2171 articles, of which 14 met our criteria for inclusion. Of the identified studies, 10 were randomized clinical trials and 4 were nonrandomized quasi-experimental studies. A secondary search to describe studies that included individuals with other forms of acquired brain injury in addition to TBI resulted in 852 additional titles, of which 5 met our inclusion criteria. DATA SYNTHESIS: Interventions that targeted the caregiver primarily were more likely to provide benefit than those that targeted caregiver/survivor dyad or the survivor only. Many of the studies were limited by poor fidelity, low sample sizes, and high risk for bias based on randomization techniques. CONCLUSIONS: Future studies of TBI caregivers should enroll a more generalizable number of participants and ensure adequate fidelity to properly compare interventions.

Factors associated with adverse outcomes in patients with traumatic intracranial hemorrhage and Glasgow Coma Scale of 15.

Patients with mild traumatic brain injury (mTBI) with associated intracranial injury, or complicated mTBI, are at risk of deterioration. Clinical management differs within and between institutions. We conducted an exploratory analysis to determine which of these patients are unlikely to have an adverse outcome and may be future targets for less resource intensive care. This single center retrospective cohort study included patients presenting to the ED with blunt complicated mTBI between January 2001 and December 2010. Patients with a Glasgow coma score (GCS) of 15, an initial head CT with a traumatic abnormality, and a repeat head CT within 24h were eligible. We defined the composite adverse outcome as death within two weeks, neurosurgical procedure within two weeks, hospitalization >48h, and worsened second head CT. Classification and Regression Tree methodology was used to identify factors associated with adverse outcomes. Of 1011 patients with two head CTs performed in a 24-h period, 240 (24%) had complicated mTBI and GCS 15. Of these, 56 (23%) experienced the composite adverse outcome defined above. Age, headache, and subarachnoid hemorrhage, correctly classified 93% of patients with an adverse outcome. No instance of death or neurosurgical procedure was missed. Our analysis highlighted three factors associated with adverse outcomes in persons who have complicated mTBI but a GCS of 15. Absence of these risk factors suggests low risk of adverse outcomes, and may suggest that a patient is safe for discharge home. Additional research is required before utilizing these findings in clinical practice.

Pre and intrahospital workflow for acute stroke treatment.

PURPOSE OF REVIEW: With the recent demonstration of the effectiveness of rapid recanalization of large vessel occlusions in acute ischemic stroke, it is important to assess the current status of pre and intrahospital workflow for acute stroke. RECENT FINDINGS: We will review trends in the evaluation and treatment of acute stroke and offer suggestions for how best to advance the workflow for acute stroke care in the coming years. SUMMARY: Future research is needed for: field use of clinical scores for predicting large vessel occlusions, telemedicine to facilitate prehospital triage, and pre and intrahospital processes for optimizing stroke care delivery.

Ethical issues in the response to Ebola virus disease in US emergency departments: a position paper of the American College of Emergency Physicians, the Emergency Nurses Association and the Society for Academic Emergency Medicine.

The 2014 outbreak of Ebola Virus Disease (EVD) in West Africa has presented a significant public health crisis to the international health community and challenged US emergency departments to prepare for patients with a disease of exceeding rarity in developed nations. With the presentation of patients with Ebola to US acute care facilities, ethical questions have been raised in both the press and medical literature as to how US emergency departments, emergency physicians, emergency nurses and other stakeholders in the healthcare system should approach the current epidemic and its potential for spread in the domestic environment. To address these concerns, the American College of Emergency Physicians, the Emergency Nurses Association and the Society for Academic Emergency Medicine developed this joint position paper to provide guidance to US emergency physicians, emergency nurses and other stakeholders in the healthcare system on how to approach the ethical dilemmas posed by the outbreak of EVD. This paper will address areas of immediate and potential ethical concern to US emergency departments in how they approach preparation for and management of potential patients with EVD.

Theoretically Based Factors Associated With Stroke Family Caregiver Health.

PURPOSE: Most persons who have had strokes are cared for at home by family members-many of whom experience depressive symptoms and quality of life changes as a result of providing care. The objective of this study is to determine theoretically based factors associated with unhealthy days in stroke family caregivers. RESEARCH DESIGN AND METHODS: Secondary data analysis was conducted using baseline data from a large randomized controlled clinical trial testing the Telephone Assessment and Skill-Building Kit program with 254 family caregivers of persons who have had strokes. Guided by a conceptual model derived from Lazarus' transactional approach to stress, data were analyzed using multiple regression with unhealthy days as the dependent variable and theoretically based factors as independent variables. RESULTS: Caregivers were mostly female (78%), White (71%), spouses (47%), or adult children (29%). Caregivers reported nine unhealthy days on average within the past month. A total of 37.8% of the variance in unhealthy days was explained by caregiver task difficulty, level of optimism, threat appraisal, depressive symptoms, and life changes with depressive symptoms being the strongest individual predictor because of shared variance. CLINICAL RELEVANCE: Unhealthy days is an important part of stroke family caregiver health. Factors associated with unhealthy days in this study provide areas to consider in future intervention development.
