RESUMO
BACKGROUND: The method of documentation during a clinical encounter may affect the patient-physician relationship. OBJECTIVES: Evaluate how the use of ambient voice recognition, coupled with natural language processing and artificial intelligence (DAX), affects the patient-physician relationship. METHODS: This was a prospective observational study with a primary aim of evaluating any difference in patient satisfaction on the Patient-Doctor Relationship Questionnaire-9 (PDRQ-9) scale between primary care encounters in which DAX was utilized for documentation as compared to another method. A single-arm open-label phase was also performed to query direct feedback from patients. RESULTS: A total of 288 patients were include in the open-label arm and 304 patients were included in the masked phase of the study comparing encounters with and without DAX use. In the open-label phase, patients strongly agreed that the provider was more focused on them, spent less time typing, and made the encounter feel more personable. In the masked phase of the study, no difference was seen in the total PDRQ-9 score between patients whose encounters used DAX (median: 45, interquartile range [IQR]: 8) and those who did not (median: 45 [IQR: 3.5]; p = 0.31). The adjusted odds ratio for DAX use was 0.8 (95% confidence interval: 0.48-1.34) for the patient reporting complete satisfaction on how well their clinician listened to them during their encounter. CONCLUSION: Patients strongly agreed with the use of ambient voice recognition, coupled with natural language processing and artificial intelligence (DAX) for documentation in primary care. However, no difference was detected in the patient-physician relationship on the PDRQ-9 scale.

BACKGROUND: The burden of documentation in the electronic medical record has been cited as a major factor in provider burnout. The aim of this study was to evaluate the association between ambient voice technology, coupled with natural language processing and artificial intelligence (DAX™), on primary care provider documentation burden and burnout. METHODS: An observational study of 110 primary care providers within a community teaching health system. The primary objectives were to determine the association between DAX™ usage and provider burnout scores on the Oldenburg Burnout Inventory (OLBI) as well as the effect on documentation time per patient encounter (minutes). RESULTS: The completion rate for the survey was 75% (83/110) and high DAX™ use (>60% of encounters) was seen in 28% of providers (23/83). High DAX™ use was associated with significantly less burnout on the OLBI disengagement sub-score (MD [Mean Difference] -2.1; 95% confidence interval [CI] -3.8 to -0.4) but not the OLBI disengagement sub-score (-1.0; 95% CI -2.9 to 1.0) or total score (MD -3.0; 95% CI -6.4 to 0.3). Nineteen providers with high implementation of DAX™ had pre and postimplementation data on documentation time per encounter. After DAX™ implementation average documentation time in notes per encounter was significantly reduced by 28.8% (1.8 min; 95% CI 1.4-2.2). CONCLUSIONS: The use of ambient voice technology during patient encounters was associated with significantly reduced documentation burden and primary care provider disengagement but not total provider burnout scores.

OBJECTIVE: To determine the incidence and significance of ventilator avoidance in patients with critical coronavirus disease 2019 (COVID-19). METHODS: This prospective observational cohort study evaluated hospital mortality and 1-year functional outcome among critically ill patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated acute respiratory distress syndrome (ARDS). The explanatory variable was ventilator avoidance, modeled as 'initial refusal' of intubation (yes/no). Modified Rankin Scale (mRS) scores were obtained from surviving patients (or their surrogates) via phone or email questionnaire. RESULTS: Among patients for whom intubation was recommended (n = 102), 40 (39%) initially refused (95% confidence interval [CI] 30%, 49%). The risk of death was 79.3% (49/62) in those who did not initially refuse intubation compared with 77.5% (31/40) in those who initially refused, with an adjusted odds ratio for death of 1.27 (95% CI 0.47, 3.48). The distribution of 1-year mRS scores was not significantly different between groups. CONCLUSION: Among critically ill patients with COVID-19-associated ARDS, ventilator avoidance was common, but was not associated with increased in-hospital mortality or 1-year functional outcome.

BACKGROUND AND OBJECTIVES: To review treatments for reducing the risk of recurrent stroke or death in patients with symptomatic intracranial atherosclerotic arterial stenosis (sICAS). METHODS: The development of this practice advisory followed the process outlined in the American Academy of Neurology Clinical Practice Guideline Process Manual, 2011 Edition, as amended. The systematic review included studies through November 2020. Recommendations were based on evidence, related evidence, principles of care, and inferences. MAJOR RECOMMENDATIONS: Clinicians should recommend aspirin 325 mg/d for long-term prevention of stroke and death and should recommend adding clopidogrel 75 mg/d to aspirin for up to 90 days to further reduce stroke risk in patients with severe (70%-99%) sICAS who have low risk of hemorrhagic transformation. Clinicians should recommend high-intensity statin therapy to achieve a goal low-density lipoprotein cholesterol level <70 mg/dL, a long-term blood pressure target of <140/90 mm Hg, at least moderate physical activity, and treatment of other modifiable vascular risk factors for patients with sICAS. Clinicians should not recommend percutaneous transluminal angioplasty and stenting for stroke prevention in patients with moderate (50%-69%) sICAS or as the initial treatment for stroke prevention in patients with severe sICAS. Clinicians should not routinely recommend angioplasty alone or indirect bypass for stroke prevention in patients with sICAS outside clinical trials. Clinicians should not recommend direct bypass for stroke prevention in patients with sICAS. Clinicians should counsel patients about the risks of percutaneous transluminal angioplasty and stenting and alternative treatments if one of these procedures is being contemplated.

OBJECTIVE: We hypothesized that healthcare workers (HCWs) with high-risk exposures outside the healthcare system would have less asymptomatic coronavirus 2019 (COVID-19) disease and more symptoms than those without such exposures. DESIGN: A longitudinal point prevalence study was conducted during August 17-September 4, 2020 (period 1) and during December 2-23, 2020 (period 2). SETTING: Community based teaching health system. PARTICIPANTS: All HCWs were invited to participate. Among HCWs who acquired COVID-19, logistic regression models were used to evaluate the adjusted odds of asymptomatic disease using high-risk exposure outside the healthcare system as the explanatory variable. The number of symptoms between exposure groups was evaluated with the Wilcoxon rank-sum test. The risk of seropositivity among all HCS by work exposure was evaluated during both periods. INTERVENTIONS: Survey and serological testing. RESULT: Seroprevalence increased from 1.9% (95% confidence interval [CI], 1.2%-2.6%) to 13.7% (95% CI, 11.9%-15.5%) during the study. Only during period 2 did HCWs with the highest work exposure (versus low exposure) have an increased risk of seropositivity (risk difference [RD], 7%; 95% CI, 1%-13%). Participants who had a high-risk exposure outside of work (compared to those without) had a decreased probability of asymptomatic disease (odds ratio [OR], 0.38; 95% CI, 0.16-0.86) and demonstrated more symptoms (median 3 [IQR, 2-6] vs 1 [IQR, 0-4]; P = .001). CONCLUSIONS: Healthcare-acquired COVID-19 increases the probability of asymptomatic or mild COVID-19 disease compared to community-acquired disease. This finding suggests that infection prevention strategies (including masks and eye protection) may be mitigating inoculum and supports the variolation theory in COVID-19.

Antiplatelet therapy at the time of spontaneous intracerebral hemorrhage (sICH) may increase risk for hemorrhage expansion and mortality. Current guidelines recommend considering a single dose of desmopressin in sICH associated with cyclooxygenase-1 inhibitors or adenosine diphosphate receptor inhibitors. Adult subjects with sICH and concomitant antiplatelet therapy admitted to a large, tertiary care center were included. We sought to compare the risk of hematoma expansion in patients that received desmopressin for antiplatelet reversal in the setting of sICH to similar patients that did not receive desmopressin. The primary outcomes were the incidence of relative and absolute hematoma expansion. In total, 71 patients (29 received desmopressin, 42 did not receive desmopressin) were analyzed. All patients in the desmopressin group received a 0.3 mcg/kg intravenous dose prior to hematoma expansion assessment. Relative hematoma expansion occurred in 5/29 (17%) with desmopressin compared to 11/42 (26%) without desmopressin (OR 0.59 [95% CI 0.18-1.92]). Absolute hematoma expansion occurred in 9/29 (30%) with desmopressin compared to 12/42 (28%) without desmopressin (OR 1.13 [95% CI 0.40-3.16]). Multiple logistic regression controlling for significant covariates did not reveal a significant effect of desmopressin on relative or absolute hematoma expansion (OR 0.65 [95% CI 0.18-2.43] and OR 1.55 [0.48-4.99], respectively). We failed to find evidence that desmopressin administration for antiplatelet reversal in sICH reduces the incidence of hematoma expansion. Larger studies, focusing on the early phase of sICH, are needed to characterize the clinical efficacy and safety of desmopressin for antiplatelet reversal before widespread implementation.

PURPOSE: Airway pressure release ventilation (APRV) utilizes high levels of airway pressure coupled with brief expiratory release to facilitate open lung ventilation. The aim of our study was to evaluate the effects of APRV-induced elevated airway pressure mean in patients with severe traumatic brain injury. MATERIALS AND METHODS: This was a retrospective cohort study at a 424-bed Level I trauma center. Linear mixed effects models were developed to assess the difference in therapeutic intensity level (TIL), intracranial pressure (ICP), and cerebral perfusion pressure (CPP) over time following the application of APRV. RESULTS: The study included 21 epochs of APRV in 21 patients. In the 6-hour epoch following the application of APRV, the TIL was significantly increased ( P = .002) and the ICP significantly decreased ( P = .041) compared to that before 6 hours. There was no significant change in CPP ( P = .42) over time. The baseline static compliance and time interaction was not significant for TIL (χ2 = 0.2 [ df 1], P = .655), CPP (χ2 = 0 [ df 1], P = 1), or ICP (χ2 = 0.1 [ df 1], P = .752). CONCLUSIONS: Application of APRV in patients with severe traumatic brain injury was associated with significantly, but not clinically meaningful, increased TIL and decreased ICP. No significant change in CPP was observed. No difference was observed based on the baseline pulmonary static compliance.

OBJECTIVE: An inflammatory response occurs after aneurysmal subarachnoid hemorrhage (aSAH) and predicts poor outcomes. Glucocorticoids suppress inflammation and promote fluid retention. Dexamethasone is often administered after aSAH for postoperative cerebral edema and refractory headache. Our objective was to examine the impact of dexamethasone use on functional outcomes and delayed cerebral ischemia (DCI) after aSAH. METHODS: Patients with aSAH admitted between 2010 and 2015 were included; the data source was a single-center subarachnoid hemorrhage registry. The intervention of interest was a dexamethasone taper used <7 days from ictus. The primary outcome was poor discharge functional outcome, with a modified Rankin Scale score >3. Other outcomes included DCI and infection. A propensity score for use of dexamethasone was calculated using a logistic regression model that included potential predictors of dexamethasone use and outcome. The impact of dexamethasone on outcomes of interest was calculated and the propensity score was controlled for. RESULTS: A total of 440 patients with subarachnoid hemorrhage were admitted during the study period and 309 met eligibility criteria. Dexamethasone was administered in 101 patients (33%). A total of 127 patients (41%) had a discharge modified Rankin Scale score >3, 105 (34%) developed DCI, and 94 (30%) developed an infection. After propensity score analysis, dexamethasone use was associated with a significant reduction in poor functional outcomes (odds ratio [OR], 0.35; 95% confidence interval [CI], 0.19-0.66) but showed no significant association with DCI (OR, 0.93; 95% CI, 0.53-1.64) or infection (OR, 0.60; 95% CI, 0.34-1.06). CONCLUSIONS: Dexamethasone use after aSAH was associated with a reduction in poor functional outcomes at discharge but not DCI, controlling for predictors of dexamethasone use.

BACKGROUND: Observational studies suggest peripherally inserted central venous catheters (PICCs) are associated with a high risk of catheter-related large vein thrombosis (CRLVT) in critically ill neurologic patients. We evaluated the difference in thrombosis risk between PICCs and centrally inserted central venous catheters (CICVCs). METHODS: We conducted a pragmatic, randomized controlled trial of critically ill adult neurologic patients admitted to neurological and trauma critical care units at two level I trauma centers. Patients were randomized to receive either a PICC or CICVC and undergo active surveillance for CRLVT or death within 15 days of catheter placement. RESULTS: In total, 39 subjects received a PICC and 41 received a CICVC between February 2012 and July 2015. The trial was stopped after enrollment of 80 subjects due to feasibility affected by slow enrollment and funding. In the primary intention-to-treat analysis, 17 (43.6 %) subjects that received a PICC compared to 9 (22.0 %) that received a CICVC experienced the composite of CRLVT or death, with a risk difference of 21.6 % (95 % CI 1.57-41.71 %). Adjusted common odds ratio of CRLVT/death was significantly higher among subjects randomized to receive a PICC (adjusted OR 3.08; 95 % CI 1.1-8.65). The higher adjusted odds ratio was driven by risk of CRLVT, which was higher in those randomized to PICC compared to CICVC (adjusted OR 4.66; 95 % CI 1.3-16.76) due to increased large vein thrombosis without a reduction in proximal deep venous thrombosis. CONCLUSIONS: Our trial demonstrates that critically ill neurologic patients who require a central venous catheter have significantly lower odds of ultrasound-diagnosed CRLVT with placement of a CICVC as compared to a PICC.

The Japanese translation of moyamoya means "puff of smoke" and refers to the angiographic appearance of dilated collateral vessels seen during chronic progressive narrowing of the intracranial supraclinoid portions of the internal carotid arteries. Despite cerebral ischemia being the most common presenting symptom, 20% to 40% of adults suffer a hemorrhagic stroke. Due to the lack of evidence and histopathologic findings, intravenous and endovascular reperfusion therapy is typically avoided. This case study presents a patient with moyamoya disease in the hyperacute phase of ischemic stroke. The patient received full dose (0.9mg/kg) tissue plasminogen activator and subsequently underwent a mechanical clot extraction and Wingspan stent (Stryker, Kalamazoo, MI, USA) placement. The use of these options in the setting of moyamoya disease is novel. This demonstrates that moyamoya disease may not be an absolute contraindication to revascularization in hyperacute ischemic stroke and underscores that many perceived contraindications to thrombolytic and mechanical revascularization therapies are relative.

OBJECTIVES: The objective of our study was to examine patients with aneurysmal subarachnoid hemorrhage transferred and directly admitted to our institution in order to determine how transfer time affects outcomes. METHODS: A retrospective cohort study was performed of all patients undergoing treatment for aneurysmal subarachnoid hemorrhage between 2005 and 2012 at the University of Michigan. Variables, including transfer time, were tested for their independent association with the primary outcomes of symptomatic vasospasm and 12-month outcome as well as secondary outcomes of aneurysm rebleeding and 12-month mortality. RESULTS: During the study period, 263 (87.4%) patients were transferred to our institution and 38 (12.6%) were directly admitted for treatment of aneurysmal subarachnoid hemorrhage. Transfer time was not associated with the occurrence of symptomatic vasospasm, 12-month outcome, rebleeding, or 12-month mortality. Higher Hunt-Hess grade was associated with the occurrence of symptomatic vasospasm as well as with poorer 12-month outcome. CONCLUSIONS: Transfer time was not associated with the occurrence of symptomatic vasospasm, 12-month outcome, rebleeding, or 12-month mortality. We believe our data argue that protocols should emphasize early resuscitation and stabilization followed by safe transfer rather than a hyperacute transfer paradigm. However, transfer time should be minimized as much as possible so as not to delay time to definitive treatment.

BACKGROUND AND PURPOSE: Our aim was to estimate the cost-effectiveness of transferring patients with intracerebral hemorrhage from centers without specialized neurological intensive care units (neuro-ICUs) to centers with neuro-ICUs. METHODS: Decision analytic models were developed for the lifetime horizons. Model inputs were derived from the best available data, informed by a variety of previous cost-effectiveness models of stroke. The effect of neuro-ICU care on functional outcomes was modeled in 3 scenarios. A favorable outcomes scenario was modeled based on the best observational data and compared with moderately favorable and least-favorable outcomes scenarios. Health benefits were measured in quality-adjusted life years (QALYs), and costs were estimated from a societal perspective. Costs were combined with QALYs gained to generate incremental cost-effectiveness ratios. One-way sensitivity analysis and Monte Carlo simulations were performed to test robustness of the model assumptions. RESULTS: Transferring patients to centers with neuro-ICUs yielded an incremental cost-effectiveness ratio for the lifetime horizon of $47,431 per QALY, $91,674 per QALY, and $380,358 per QALY for favorable, moderately favorable, and least-favorable scenarios, respectively. Models were robust at a willingness-to-pay threshold of $100,000 per QALY, with 95.5%, 75.0%, and 2.1% of simulations below the threshold for favorable, moderately favorable, and least-favorable scenarios, respectively. CONCLUSIONS: Transferring patients with intracerebral hemorrhage to centers with specialized neuro-ICUs is cost-effective if observational estimates of the neuro-ICU-based functional outcome distribution are accurate. If future work confirms these functional outcome distributions, then a strong societal rationale exists to build systems of care designed to transfer intracerebral hemorrhage patients to specialized neuro-ICUs.

Mannitol has been shown to damage endothelial cells and activate coagulation pathways leading to intravascular thrombosis. Dehydration and hemagglutination have also been associated with mannitol use, although the risk of clinically evident venous thromboembolism (VTE) disease is not well-defined. The aim of this study was to compare the risk of VTE in critically ill neurological patients who received mannitol compared to only hypertonic saline. A case-cohort study design with propensity score matching was used to evaluate the risk of VTE among patients who received mannitol compared to those who received hypertonic saline alone. The odds of thrombosis were evaluated by the Cochran-Mantel-Haenszel method and conditional logistic regression was used to adjust for year of treatment. Ninety-one of 330 patients (27.6%; 95% confidence interval [CI] 23-33%) developed a VTE; however, the yearly proportion remained unchanged over the 8 year study period. Cumulative use of mannitol declined and use of hypertonic saline increased significantly. The odds of thrombosis for those exposed to mannitol compared to hypertonic saline alone was 1.11 (95% CI 0.65-1.73; p=0.75). This remained insignificant after adjusting for year of injury. In conclusion, despite a significant change in the pattern of osmotic therapy used at our institution, the proportion of patients with VTE remained unchanged. We found no evidence that mannitol use was associated with VTE compared to hypertonic saline alone.

BACKGROUND: Neurocardiogenic injury results from increased sympathetic nervous system activation following acute brain injury. No diagnostic criteria for neurocardiogenic injury exist, and agreement has not been tested. We investigated the agreement by neurointensivists for the presence of neurocardiogenic injury on routine cardiac studies. METHODS: Six neurointensivists rated 100 consecutive cases of aneurysmal subarachnoid hemorrhage (aSAH) for the presence of neurocardiogenic injury. A fixed-panel design was employed for the agreement among the whole cohort, as well as stratified by modified Fisher Scale (mFs), Hunt and Hess grade, gender, and the presence of elevated cardiac enzymes. Overall percent agreement, paired agreement, and agreement above change (Fleiss' Kappa) were calculated. Overall percent agreement between groups was compared using Chi square tests. RESULTS: Six raters completed the survey for a total 600 responses. Overall percent agreement was 79.3 %, and agreement among cases at least one rater thought had neurocardiogenic injury was 66.5 % (paired agreement). Fleiss' Kappa was 0.66 (95 % CI, 0.1-0.71; p < 0.0001), indicating substantial agreement above chance. Similarly, on subgroup analysis, significant agreement beyond chance was seen in all groups (p < 0.001). Overall percent agreement was significantly better among mFs 3-4 compared to mFs ≤ 2 (81.3 vs. 63.6 %; p = 0.018) and among cases with positive cTI (96.9 vs. 70.1 %; p ≤ 0.001). CONCLUSIONS: Overall, we demonstrated substantial agreement for the presence of neurocardiogenic injury on early cardiac studies following aSAH. However, inter-observer variability increased when evaluating patients without the objective finding of elevated cTI and among those with lower clinical and radiographic grades.

BACKGROUND: Autonomic shift (AS), characterized by increased sympathetic nervous system activation, has been implicated in neurologically mediated cardiopulmonary dysfunction and immunodepression after stroke. We investigated the prevalence of AS defined by readily available clinical parameters and determined the association of AS with subsequent infection in a cohort of patients with aneurysmal subarachnoid hemorrhage (aSAH). METHODS: Data were obtained from a single-center cohort study of aSAH patients admitted from January 1, 2007, through April 1, 2012. AS was defined as at least 1 early (<72 hours) routine clinical marker of neurologically mediated cardiopulmonary dysfunction based on electrocardiogram, echocardiogram, cardiac enzymes, or neurogenic pulmonary edema. Multivariable logistic regression models were developed to evaluate the association between AS and subsequent infection after adjusting for other covariates. RESULTS: A total of 167 patients were included in the analysis (mean age 56, 27% men). AS was seen in 66 of 167 patients (40%; 95% confidence interval [CI], 32%-47%), and infection was seen in 80 of 167 patients (48%; 95% CI, 40%-55%). AS was associated with subsequent infection on unadjusted analysis (odds ratio [OR] 2.11; 95% CI, 1.12-3.97); however, this association was no longer significant when adjusting for other predictors of infection (OR 1.36; 95% CI, .67-2.76). Age, clinical grade, and aneurysm location were all independent predictors of infection after aSAH. CONCLUSIONS: We identified AS based on readily available clinical markers in 40% of patients with aSAH, though AS defined by these clinical criteria was not an independent predictor of infection. Additional studies may be warranted to determine the optimal definition of AS and the clinical significance of this finding.

OBJECT: The authors conducted a study to review outcomes and management in patients in whom intracranial hemorrhage (ICH) develops during left ventricular assist device (LVAD) therapy. METHODS: This retrospective cohort study included all adult patients (18 years of age or older) at a single institution who underwent placement of an LVAD between January 1, 2003, and March 1, 2012. The authors conducted a detailed medical chart review, and data were abstracted to assess outcomes in patients in whom ICH developed compared to those in patients in whom ICH did not develop; to compare management of antiplatelet agents and anticoagulation with outcomes; to describe surgical management employed and outcomes achieved; to compare subtypes of ICH (intraparenchymal, subdural, and subarachnoid hemorrhage) and their outcomes; and to determine any predictors of outcome. RESULTS: During the study period, 330 LVADs were placed and 36 patients developed an ICH (traumatic subarachnoid hemorrhage in 10, traumatic subdural hematoma in 8, spontaneous intraventricular hemorrhage in 1, and spontaneous intraparenchymal hemorrhage in 17). All patients were treated with aspirin and warfarin at the time of presentation. With suspension of these agents, no thromboembolic events or pump failures were seen and no delayed rehemorrhages occurred after resuming these medications. Intraparenchymal hemorrhages had the worst outcomes, with a 30-day mortality rate in 59% compared with a 30-day mortality rate of 0% in patients with traumatic subarachnoid hemorrhages and 13% in those with traumatic subdural hematomas. Five patients with intraparenchymal hemorrhages were managed with surgical intervention, 4 of whom died within 60 days. The only factor found to be predictive of outcome was initial Glasgow Coma Scale score. No patients with a Glasgow Coma Scale score less than 11 survived beyond 30 days. Overall, the development of an ICH significantly reduced survival compared with the natural history of patients on LVAD therapy. CONCLUSIONS: The authors' data suggest that withholding aspirin for 1 week and warfarin for 10 days is sufficient to reduce the risk of hemorrhage expansion or rehemorrhage while minimizing the risk of thromboembolic events and pump failure. Patients with intraparenchymal hemorrhage have poor outcomes, whereas patients with traumatic subarachnoid hemorrhage or subdural hematoma have better outcomes.

OBJECTIVE: To compare cumulative complication rates of peripherally (PICC) and centrally (CICVC) inserted central venous catheters, including catheter-related large vein thrombosis (CRLVT), central line-associated bloodstream infection (CLABSI), and line insertion-related complications in neurological intensive care patients. METHODS: Retrospective cohort study and detailed chart review for 431 consecutive PICCs and 141 CICVCs placed in patients under neurological intensive care from March 2008 through February 2010. Cumulative incidence of CRLVT, CLABSI, and line insertion-related complications were compared between PICC and CICVC groups. Risk factors for CRLVT including mannitol therapy during dwell time, previous history of venous thromboembolism, surgery longer than 1h during dwell time, and line placement in a paretic arm were also compared between groups. RESULTS: During the study period, 431 unique PICCs were placed with cumulative incidence of symptomatic thrombosis of 8.4%, CLABSI 2.8%, and line insertion-related complications 0.0%. During the same period, 141 unique CICVCs were placed with cumulative incidence of symptomatic thrombosis of 1.4%, CLABSI 1.4%, and line insertion-related complications 0.7%. There was a statistically significant difference in CRLVT with no difference in CLABSI or line insertion-related complications. CONCLUSIONS: In neurological critical care patients, CICVCs appear to have a better risk profile compared to PICCs, with a decreased risk of CRLVT. As use of PICCs in critical care patients increases, a prospective randomized trial comparing PICCs and CICVCs in neurological critical care patients is necessary to assist in choosing the appropriate catheter and to minimize risks of morbidity and mortality associated with central venous access.
