RESUMEN

Importance: Fever is associated with worse outcomes in patients with stroke, but whether preventing fever improves outcomes is unclear. Objective: To determine whether fever prevention after acute vascular brain injury is achievable and impacts functional outcome. Design, Setting, and Participants: Open-label randomized clinical trial with blinded outcome assessment that enrolled 686 of 1176 planned critically ill patients with stroke at 43 intensive care units in 7 countries from March 2017 to April 2021 (last date of follow-up was May 12, 2022). Intervention: Patients randomized to fever prevention (n = 339) were targeted to 37.0 °C for 14 days or intensive care unit discharge using an automated surface temperature management device. Standard care patients (n = 338) received standardized tiered fever treatment on occurrence of temperature of 38 °C or greater. Main Outcomes and Measures: Primary outcome was daily mean fever burden: the area under the temperature curve above 37.9 °C (total fever burden) divided by the total number of hours in the acute phase, multiplied by 24 hours (°C-hour). The principal secondary outcome was 3-month functional recovery by shift analysis of the 6-category modified Rankin Scale, which is scored from 0 (no symptoms) to 6 (death). Major adverse events included death, pneumonia, sepsis, and malignant cerebral edema. Results: Enrollment was stopped after a planned interim analysis demonstrated futility of the principal secondary end point. In total, 686 patients were enrolled, and 9 were consented but not randomized, leaving a primary analysis population of 677 patients (254 ischemic stroke, 223 intracerebral hemorrhage, 200 subarachnoid hemorrhage; 345 were female [51%]; median age, 62 years) with 433 (64%) completing the study through 12 months. Daily mean (SD) fever burden was significantly lower in the fever prevention group (0.37 [1.0] °C-hour; range, 0.0-8.0 °C-hour) compared with the standard care group (0.73 [1.1] °C-hour; range, 0.0-10.3 °C-hour) (difference, -0.35 [95% CI, -0.51 to -0.20]; P < .001). Between-group differences for the primary outcome by stroke subtype were -0.10 (95% CI, -0.35 to 0.15) for ischemic stroke, -0.50 (95% CI, -0.78 to -0.22) for intracerebral hemorrhage, and -0.52 (95% CI, -0.81 to -0.23) for subarachnoid hemorrhage (all P < .001 by Wilcoxon rank-sum test). There was no significant difference in functional recovery at 3 months (median modified Rankin Scale score, 4.0 vs 4.0, respectively; odds ratio for a favorable shift in functional outcome, 1.09 [95% CI, 0.81 to 1.46]; P = .54). Major adverse events occurred in 82.2% of participants in the fever prevention group vs 75.9% in the standard care group, including 33.8% vs 34.5% for infections, 14.5% vs 14.0% for cardiac disorders, and 24.5% vs 20.5% for respiratory disorders. Conclusions and Relevance: In patients with acute vascular brain injury, preventive normothermia using an automated surface temperature management device effectively reduced fever burden but did not improve functional outcomes.

RESUMEN

BACKGROUND: To facilitate comparative research, it is essential for the fields of neurocritical care and rehabilitation to establish common data elements (CDEs) for disorders of consciousness (DoC). Our objective was to identify CDEs related to goals-of-care decisions and family/surrogate decision-making for patients with DoC. METHODS: To achieve this, we formed nine CDE working groups as part of the Neurocritical Care Society's Curing Coma Campaign. Our working group focused on goals-of-care decisions and family/surrogate decision-makers created five subgroups: (1) clinical variables of surrogates, (2) psychological distress of surrogates, (3) decision-making quality, (4) quality of communication, and (5) quality of end-of-life care. Each subgroup searched for existing relevant CDEs in the National Institutes of Health/CDE catalog and conducted an extensive literature search for additional relevant study instruments to be recommended. We classified each CDE according to the standard definitions of "core", "basic", "exploratory", or "supplemental", as well as their use for studying the acute or chronic phase of DoC, or both. RESULTS: We identified 32 relevant preexisting National Institutes of Health CDEs across all subgroups. A total of 34 new instruments were added across all subgroups. Only one CDE was recommended as disease core, the "mode of death" of the patient from the clinical variables subgroup. CONCLUSIONS: Our findings provide valuable CDEs specific to goals-of-care decisions and family/surrogate decision-making for patients with DoC that can be used to standardize studies to generate high-quality and reproducible research in this area.

RESUMEN

BACKGROUND: Multiple studies demonstrate that fever/elevated temperature is associated with poor outcomes in patients with vascular brain injury; however, there are no conclusive studies that demonstrate that fever prevention/controlled normothermia is associated with better outcomes. The primary objective of the INTREPID (Impact of Fever Prevention in Brain-Injured Patients) trial is to test the hypothesis that fever prevention is superior to standard temperature management in patients with acute vascular brain injury. METHODS: INTREPID is a prospective randomized open blinded endpoint study of fever prevention versus usual care in patients with ischemic or hemorrhagic stroke. The fever prevention intervention utilizes the Arctic Sun System and will be compared to standard care patients in whom fever may spontaneously develop. Ischemic stroke, intracerebral hemorrhage or subarachnoid hemorrhage patients will be included within disease-specific time-windows. Both awake and sedated patients will be included, and treatment is initiated immediately upon enrollment. Eligible patients are expected to require intensive care for at least 72 h post-injury, will not be deemed unlikely to survive without severe disability, and will be treated for up to 14 days, or until deemed ready for discharge from the ICU, whichever comes first. Fifty sites in the USA and worldwide will participate, with a target enrollment of 1176 patients (1000 evaluable). The target temperature is 37.0 °C. The primary efficacy outcome is the total fever burden by °C-h, defined as the area under the temperature curve above 37.9 °C. The primary secondary outcome, on which the sample size is based, is the modified Rankin Scale Score at 3 months. All efficacy analyses including the primary and key secondary endpoints will be primarily based on an intention-to-treat population. Analysis of the as-treated and per protocol populations will also be performed on the primary and key secondary endpoints as sensitivity analyses. DISCUSSION: The INTREPID trial will provide the first results of the impact of a pivotal fever prevention intervention in patients with acute stroke ( www.clinicaltrials.gov ; NCT02996266; registered prospectively 05DEC2016).

RESUMEN

BACKGROUND/OBJECTIVE: Informal caregivers (e.g., family and friends) are at risk for developing depression, which can be detrimental to both caregiver and patient functioning. Initial evidence suggests that resiliency may reduce the risk of depression. However, gender differences in associations between multiple psychosocial resiliency factors and depression have not been examined among neuroscience intensive care unit (neuro-ICU) caregivers. We explored interactions between caregiver gender and baseline resiliency factors on depression symptom severity at baseline through 3 and 6 months post-discharge. METHODS: Caregivers (N = 96) of neuro-ICU patients able to provide informed consent to participate in research were enrolled as part of a prospective, longitudinal study in the neuro-ICU of a major academic medical center. Caregiver sociodemographics and resiliency factors (coping, mindfulness, self-efficacy, intimate care, and preparedness for caregiving) were assessed during the patient's hospitalization (i.e., baseline). Levels of depressive symptoms were measured using the Hospital Anxiety and Depression Scale at baseline, 3 months, and 6 months post-discharge. RESULTS: Baseline depressive symptoms predicted depressive symptoms at both 3- and 6-month follow-ups, with no difference at any time point in rates of depression by gender. At baseline, greater levels of coping, mindfulness, and preparedness for caregiving were individually associated with lower levels of concurrent depression regardless of gender (ps < 0.006). The main effect of baseline coping remained significant at 3-month follow-up (p = 0.045). We observed a trend-level interaction between gender and baseline intimate care, such that among male caregivers only, high baseline intimate care was associated with lower depression at 3-month follow-up (p = 0.055). At 6-month follow-up, we observed a significant interaction between caregiver gender and baseline intimate care, such that male caregivers reporting high intimate care reported lower symptoms of depression than females reporting high intimate care (p = 0.037). CONCLUSIONS: Results support implementation of psychosocial resiliency interventions for caregivers of patients admitted to the neuro-ICU early in the recovery process. Male caregivers may particularly benefit from strategies focused on increasing intimate care (e.g., physical and emotional affection with their loved one) and quality of the patient-caregiver dyadic relationship.

RESUMEN

BACKGROUND: Targeted temperature management (TTM) is often used in neurocritical care to minimize secondary neurologic injury and improve outcomes. TTM encompasses therapeutic hypothermia, controlled normothermia, and treatment of fever. TTM is best supported by evidence from neonatal hypoxic-ischemic encephalopathy and out-of-hospital cardiac arrest, although it has also been explored in ischemic stroke, traumatic brain injury, and intracranial hemorrhage patients. Critical care clinicians using TTM must select appropriate cooling techniques, provide a reasonable rate of cooling, manage shivering, and ensure adequate patient monitoring among other challenges. METHODS: The Neurocritical Care Society recruited experts in neurocritical care, nursing, and pharmacotherapy to form a writing Committee in 2015. The group generated a set of 16 clinical questions relevant to TTM using the PICO format. With the assistance of a research librarian, the Committee undertook a comprehensive literature search with no back date through November 2016 with additional references up to March 2017. RESULTS: The Committee utilized GRADE methodology to adjudicate the quality of evidence as high, moderate, low, or very low based on their confidence that the estimate of effect approximated the true effect. They generated recommendations regarding the implementation of TTM based on this systematic review only after considering the quality of evidence, relative risks and benefits, patient values and preferences, and resource allocation. CONCLUSION: This guideline is intended for neurocritical care clinicians who have chosen to use TTM in patient care; it is not meant to provide guidance regarding the clinical indications for TTM itself. While there are areas of TTM practice where clear evidence guides strong recommendations, many of the recommendations are conditional, and must be contextualized to individual patient and system needs.

RESUMEN

External ventricular drains (EVDs) are commonly placed to monitor intracranial pressure and manage acute hydrocephalus in patients with a variety of intracranial pathologies. The indications for EVD insertion and their efficacy in the management of these various conditions have been previously addressed in guidelines published by the Brain Trauma Foundation, American Heart Association and combined committees of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons. While it is well recognized that placement of an EVD may be a lifesaving intervention, the benefits can be offset by procedural and catheter-related complications, such as hemorrhage along the catheter tract, catheter malposition, and CSF infection. Despite their widespread use, there are a lack of high-quality data regarding the best methods for placement and management of EVDs to minimize these risks. Existing recommendations are frequently based on observational data from a single center and may be biased to the authors' view. To address the need for a comprehensive set of evidence-based guidelines for EVD management, the Neurocritical Care Society organized a committee of experts in the fields of neurosurgery, neurology, neuroinfectious disease, critical care, pharmacotherapy, and nursing. The Committee generated clinical questions relevant to EVD placement and management. They developed recommendations based on a thorough literature review using the Grading of Recommendations Assessment, Development, and Evaluation system, with emphasis placed not only on the quality of the evidence, but also on the balance of benefits versus risks, patient values and preferences, and resource considerations.

RESUMEN

ABSTRACT: BACKGROUND: The essential components of an effective neuroscience nurse orientation program for those caring for the adult general care population have not been well defined or standardized. METHODS : Using a 2-round, modified Delphi methodology, electronic surveys were distributed to 53 experts in neuroscience nursing orientation to gain consensus on the essential components of orientation for the neuroscience nurse. Survey data included demographics of the expert, literature-based components of neuroscience nurse orientation, and an opportunity to agree/disagree or write in additional components. RESULTS : Round 1 of the consensus survey elicited a response rate of 55% (29/53), and round 2 had a 51% (27/53) response rate. On the basis of round 1 expert responses, 4 new orientation components were added, and 36 components of a neuroscience nursing orientation were revised to include only the elements with ≥75% agreement. Twenty-two elements in round 2 met the criteria of ≥75% very important and important to include as components of a neuroscience nursing orientation. CONCLUSION : An expert consensus was reached on the necessary components of a neuroscience nursing orientation. The identified neuroscience nursing orientation components concentrated on improving nursing practice and provision of care to adult neuroscience patients. This study demonstrates priority components within a standardized orientation program for neuroscience nurses based on literature and expert consensus. A comprehensive neuroscience nursing orientation is a vital step in sustaining high-quality care for patients and improving neurological outcomes.

RESUMEN

BACKGROUND: Extubation failure in the neurocritical care unit (NCCU) is difficult to predict, and is an important source of prolonged intensive care, exposure to morbidity, and increased cost. METHODS: In this observational cohort study in the NCCU of a tertiary care hospital, we examined patients undergoing extubation or tracheostomy with >6 h of intubation. Observational data were collected at the time of the decision to extubate or pursue tracheostomy. The primary end-point was extubation failure within 72 h. RESULTS: A total of 378 tracheostomy versus extubation decisions were made on 339 individuals, resulting in 93 tracheostomies and 285 extubations. The extubation failure rate was 48/285 (16.8%). Individuals who underwent extubation had similar GCS scores [median 10T (IQR 10-11), P = 0.21]. Extubation failures had similar rates of pneumonia and fever, chest X-ray (CXR) findings, and admission diagnoses (P = NS). Factors associated with success in univariate analysis included intact gag reflex, normal eye movements, ability to close eyes to command, and ability to cough to command (all P < 0.05). In multivariate analysis, the ability to follow four commands (close eyes, show two fingers, wiggle toes, cough to command) was associated with success (P = 0.01). ROC analysis identified a significant difference in favor of a multivariate model incorporating four commands over GCS alone (P = 0.007). CONCLUSION: The ability to follow four commands and other examination criteria were strongly associated with extubation success in this observational study. Modeling suggests that specific neurologic examination parameters provide additional predictive information over GCS alone. A prospective, protocol-driven trial is needed to test and expand these findings.

RESUMEN

Malignant hemispheric stroke occurs in 10% of ischemic strokes and has one of the highest mortality and morbidity rates. This stroke, also known as malignant middle cerebral artery stroke, may cause ischemia to an entire hemisphere causing edema, herniation, and death. A collaborative interdisciplinary team approach is needed to manage these complex stroke patients. The nurse plays a vital role in bedside management and support of the patient and family through this complex course of care. This article discusses malignant middle cerebral artery stroke pathophysiology, techniques to predict patients at risk for herniation, collaborative care strategies, and nursing care.

RESUMEN

OBJECTIVE: There is variability and uncertainty about the optimal approach to the management and discontinuation of an external ventricular drain (EVD) after subarachnoid hemorrhage (SAH). Evidence from single-center randomized trials suggests that intermittent CSF drainage and rapid EVD weans are safe and associated with shorter ICU length of stay (LOS) and fewer EVD complications. However, a recent survey revealed that most neurocritical care units across the United States employ continuous CSF drainage with a gradual wean strategy. Therefore, the authors sought to determine the optimal EVD management approach at their institution. METHODS: The authors reviewed records of 200 patients admitted to their institution from 2010 to 2016 with aneurysmal SAH requiring an EVD. In 2014, the neurocritical care unit of the authors' institution revised the internal EVD management guidelines from a continuous CSF drainage with gradual wean approach (continuous/gradual) to an intermittent CSF drainage with rapid EVD wean approach (intermittent/rapid). The authors performed a retrospective multivariable analysis to compare outcomes before and after the guideline change. RESULTS: The authors observed a significant reduction in ventriculoperitoneal (VP) shunt rates after changing to an intermittent CSF drainage with rapid EVD wean approach (13% intermittent/rapid vs 35% continuous/gradual, OR 0.21, p = 0.001). There was no increase in delayed VP shunt placement at 3 months (9.3% vs 8.6%, univariate p = 0.41). The intermittent/rapid EVD approach was also associated with a shorter mean EVD duration (10.2 vs 15.6 days, p < 0.001), shorter ICU LOS (14.2 vs 16.9 days, p = 0.001), shorter hospital LOS (18.2 vs 23.7 days, p < 0.0001), and lower incidence of a nonfunctioning EVD (15% vs 30%, OR 0.29, p = 0.006). The authors found no significant differences in the rates of symptomatic vasospasm (24.6% vs 20.2%, p = 0.52) or ventriculostomy-associated infections (1.3% vs 8.8%, OR 0.30, p = 0.315) between the 2 groups. CONCLUSIONS: An intermittent CSF drainage with rapid EVD wean approach is associated with fewer VP shunt placements, fewer complications, and shorter LOS compared to a continuous CSF drainage with gradual EVD wean approach. There is a critical need for prospective multicenter studies to determine if the authors' experience is generalizable to other centers.

RESUMEN

More than 700,000 people have a stroke each year in the United States. A diagnosis of stroke formerly elicited a nihilistic approach, but this has substantially changed in the last decade. Currently, time is brain, and it is important for all disciplines to work together to initiate acute stroke protocols in the emergency department and identify patients within the therapeutic time window for thrombolytic and neuroprotective therapies. Evolving protocols, management, and nursing care all have important implications during the acute phase of ischemic stroke. Patient and family education on risk reduction must also be addressed by the entire healthcare team.

RESUMEN

PURPOSE: Continuous EEG screening using spectrograms or compressed spectral arrays (CSAs) by neurophysiologists has shorter review times with minimal loss of sensitivity for seizure detection when compared with visual analysis of raw EEG. Limited data are available on the performance characteristics of CSA-based seizure detection by neurocritical care nurses. METHODS: This is a prospective cross-sectional study that was conducted in two academic neurocritical care units and involved 33 neurointensive care unit nurses and four neurophysiologists. RESULTS: All nurses underwent a brief training session before testing. Forty two-hour CSA segments of continuous EEG were reviewed and rated for the presence of seizures. Two experienced clinical neurophysiologists masked to the CSA data performed conventional visual analysis of the raw EEG and served as the gold standard. The overall accuracy was 55.7% among nurses and 67.5% among neurophysiologists. Nurse seizure detection sensitivity was 73.8%, and the false-positive rate was 1-per-3.2 hours. Sensitivity and false-alarm rate for the neurophysiologists was 66.3% and 1-per-6.4 hours, respectively. Interrater agreement for seizure screening was fair for nurses (Gwet AC1 statistic: 43.4%) and neurophysiologists (AC1: 46.3%). CONCLUSIONS: Training nurses to perform seizure screening utilizing continuous EEG CSA displays is feasible and associated with moderate sensitivity. Nurses and neurophysiologists had comparable sensitivities, but nurses had a higher false-positive rate. Further work is needed to improve sensitivity and reduce false-alarm rates.

RESUMEN

BACKGROUND: Pressure ulcers resulting from continuous EEG (cEEG) monitoring in hospitalized patients have gained attention as a preventable medical complication. We measured their incidence and risk factors. METHODS: We performed an observational investigation of cEEG-electrode-related pressure ulcers (EERPU) among acutely ill patients over a 22-month period. Variables analyzed included age, sex, monitoring duration, hospital location, application methods, vasopressor usage, nutritional status, skin allergies, fever, and presence/severity of EERPU. We examined risk for pressure ulcers vs monitoring duration using Kaplan-Meyer survival analysis, and performed multivariate risk assessment using Cox proportional hazard model. RESULTS: Among 1,519 patients, EERPU occurred in 118 (7.8%). Most (n = 109, 92.3%) consisted of hyperemia only without skin breakdown. A major predictor was monitoring duration, with 3-, 5-, and 10-day risks of 16%, 32%, and 60%, respectively. Risk factors included older age (mean age 60.65 vs 50.3, p < 0.01), care in an intensive care unit (9.37% vs 5.32%, p < 0.01), lack of a head wrap (8.31% vs 27.3%, p = 0.02), use of vasopressors (16.7% vs 9.64%, p < 0.01), enteral feeding (11.7% vs 5.45%, p = 0.04), and fever (18.4% vs 9.3%, p < 0.01). Elderly patients (71-80 years) were at higher risk (hazard ratio 6.84 [1.95-24], p < 0.01), even after accounting for monitoring time and other pertinent variables in multivariate analysis. CONCLUSIONS: EERPU are uncommon and generally mild. Elderly patients and those with more severe illness have higher risk of developing EERPU, and the risk increases as a function of monitoring duration.

RESUMEN

Delayed cerebral ischemia (DCI) is the most common and disabling complication among patients admitted to the hospital for subarachnoid hemorrhage (SAH). Clinical and radiographic methods often fail to detect DCI early enough to avert irreversible injury. We assessed the clinical feasibility of implementing a continuous EEG (cEEG) ischemia monitoring service for early DCI detection as part of an institutional guideline. An institutional neuromonitoring guideline was designed by an interdisciplinary team of neurocritical care, clinical neurophysiology, and neurosurgery physicians and nursing staff and cEEG technologists. The interdisciplinary team focused on (1) selection criteria of high-risk patients, (2) minimization of safety concerns related to prolonged monitoring, (3) technical selection of quantitative and qualitative neurophysiologic parameters based on expert consensus and review of the literature, (4) a structured interpretation and reporting methodology, prompting direct patient evaluation and iterative neurocritical care, and (5) a two-layered quality assurance process including structured clinician interviews assessing events of neurologic worsening and an adjudicated consensus review of neuroimaging and medical records. The resulting guideline's clinical feasibility was then prospectively evaluated. The institutional SAH monitoring guideline used transcranial Doppler ultrasound and cEEG monitoring for vasospasm and ischemia monitoring in patients with either Fisher group 3 or Hunt-Hess grade IV or V SAH. Safety criteria focused on prevention of skin breakdown and agitation. Technical components included monitoring of transcranial Doppler ultrasound velocities and cEEG features, including quantitative alpha:delta ratio and percent alpha variability, qualitative evidence of new focal slowing, late-onset epileptiform activity, or overall worsening of background. Structured cEEG reports were introduced including verbal communication for findings concerning neurologic decline. The guideline was successfully implemented over 27 months, during which neurocritical care physicians referred 71 SAH patients for combined transcranial Doppler ultrasound and cEEG monitoring. The quality assurance process determined a DCI rate of 48% among the monitored population, more than 90% of which occurred during the duration of cEEG monitoring (mean 6.9 days) beginning 2.7 days after symptom onset. An institutional guideline implementing cEEG for SAH ischemia monitoring and reporting is feasible to implement and efficiently identify patients at high baseline risk of DCI during the period of monitoring.

RESUMEN

Many prior nursing studies regarding family members specifically of neuroscience intensive care unit (neuro-ICU) patients have focused on identifying their primary needs. A concept related to identifying these needs and assessing whether they have been met is determining whether families explicitly report satisfaction with the care that both they and their loved ones have received. The objective of this study was to explore family satisfaction with care in an academic neuro-ICU and compare results with concurrent data from the same hospital's medical ICU (MICU). Over 38 days, we administered the Family Satisfaction-ICU instrument to neuro-ICU and MICU patients' families at the time of ICU discharge. Those whose loved ones passed away during ICU admission were excluded. When asked about the respect and compassion that they received from staff, 76.3% (95% CI [66.5, 86.1]) of neuro-ICU families were completely satisfied, as opposed to 92.7% in the MICU (95% CI [84.4, 101.0], p = .04). Respondents were less likely to be completely satisfied with the courtesy of staff if they reported participation in zero formal family meeting. Less than 60% of neuro-ICU families were completely satisfied by (1) frequency of physician communication, (2) inclusion and (3) support during decision making, and (4) control over the care of their loved ones. Parents of patients were more likely than other relatives to feel very included and supported in the decision-making process. Future studies may focus on evaluating strategies for neuro-ICU nurses and physicians to provide better decision-making support and to implement more frequent family meetings even for those patients who may not seem medically or socially complicated to the team. Determining satisfaction with care for those families whose loved ones passed away during their neuro-ICU admission is another potential avenue for future investigation.

RESUMEN

PURPOSE: Prior studies of anxiety and depression among families of intensive care unit patients excluded those admitted for less than 2 days. We hypothesized that families of surviving patients with length of stay less than 2 days would have similar prevalence of anxiety and depression compared with those admitted for longer. MATERIALS AND METHODS: One hundred six family members in the neurosciences and medical intensive care units at a university hospital completed the Hospital Anxiety and Depression Scale at discharge. RESULTS: The 106 participants represented a response rate of 63.9% among those who received surveys. Fifty-eight surveys (54.7%) were from relatives of patients who were discharged within 2 days of admission, whereas 48 (45.3%) were from those admitted for longer. No difference in anxiety was detected; prevalence was 20.7% (95% confidence interval, 10.4) among shorter stay families and 8.3% (7.8) among longer stay families (P = .10). No difference was also seen with depression; prevalence was 8.6% (7.2) among shorter stay families and 4.2% (5.7) among longer stay families (P = .45). CONCLUSIONS: Families of surviving patients with brief length of stay may have similar prevalence of anxiety and depression at discharge to those with longer length of stay.

RESUMEN

PURPOSE: We hypothesize that intensive care unit (ICU) families frequently perceive that they have received inconsistent information from staff about their relatives and that these inconsistencies influence abilities to make medical decisions, as well as satisfaction. MATERIALS AND METHODS: We performed a prospective cohort study in the neurosciences and medical ICU at a university hospital. One hundred twenty-four family members of adult patients surviving to ICU discharge completed a questionnaire regarding perceptions of inconsistent information. RESULTS: Of 193 eligible patients, 64.2% had family complete the survey. Thirty-one respondents (25.0%; 95% confidence interval, 7.7) reported at least 1 instance of inconsistent information during their family member's admission, with no difference between the neurosciences ICU (21.5%; 9.3) and the medical ICU (31.1%; 14.1; P = .28). Of those who did receive inconsistent information, 38.7% (95% confidence interval, 18.2) reported multiple episodes and 74.2% (16.3) indicated that episodes occurred within the first 48 hours of admission. These episodes had an adverse effect, with 19.4% (14.7) indicating that they affected satisfaction and 9.7% (11.0) indicating that they made decision making difficult. CONCLUSIONS: Episodes involving inconsistent information from staff as perceived by families may be quite prevalent and may influence decision-making abilities and satisfaction.
