RESUMO
BACKGROUND: Delirium has conventionally been considered a disorder of consciousness. Alertness and arousal are used as surrogates in clinical practice but are insufficient for the purposes of a more dimensional assessment of consciousness. We present a process of development and validation of candidate measures of phenomenal consciousness that could be applied to the diagnosis of delirium. METHODS: First, a narrative review of available instruments in the fields of phenomenal consciousness, including prereflective consciousness, the phenomenal-sensed experience and reflective thought, was undertaken. Eligibility of tools in the context of applicability to delirium was based upon objectivity in test interpretation and the requirement for tester administration. Second, where there was a gap in suitable cognitive tools, new items were derived using the silent generation technique. A process of face and construct validity using a diverse panel of experts was performed, and readability was evaluated. RESULTS: 814 articles were screened from the literature review. Fourteen candidate tools were reported from the three domains of phenomenal consciousness. One of these met the eligibility criteria for a delirium assessment. Fifty-seven new tests of phenomenal consciousness were identified. After a process of item reduction, a total of 26 individual tests were identified. After content validity, 22 of the 26 items were retained. The scale average content validity index was 0.89. The agreement between raters was between 80% and 97%. 100% of responses for face validity were rated as positive. Flesch Reading Ease Score was 91.6 (very easy to read). CONCLUSIONS: Candidate measures of phenomenal consciousness are described, and early validity studies are promising.

OBJECTIVE: To examine the utility of head and trunk control, assessed using the Physical Abilities and Mobility Scale, for predicting emergence from a minimally conscious state (eMCS) among children with acquired brain injury admitted to inpatient rehabilitation in a disorder of consciousness (DoC). DESIGN: Retrospective study. SETTING: Pediatric inpatient rehabilitation hospital. PARTICIPANTS: Forty patients (2-21 years-old) directly admitted from acute care to pediatric inpatient brain injury rehabilitation in a DoC (average length of stay=85 days; N=40). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: State of consciousness (eMCS vs not) at discharge from inpatient rehabilitation. RESULTS: Forty-five percent of patients emerged from a minimally conscious state during inpatient rehabilitation. Admission state of consciousness and head control (but not trunk control) were significantly associated with eMCS and provided complementary prognostic information. Admission state of consciousness (ie, admitting in a vegetative state/unresponsive wakefulness syndrome) afforded the greatest negative predictive value (93.8%), whereas admission head control ability afforded the greatest positive predictive value (81.8% for any independent head control; 100% for maintaining head-up position for >30 seconds). Fifty percent of patients who emerged during the inpatient stay did not have independent head control at admission, highlighting the importance of exploring head control as a prognostic marker in conjunction with indicators with greater sensitivity (eg, state of consciousness at admission). CONCLUSIONS: A brief measure of head control at admission may contribute to identification of a subgroup of patients who are likely to emerge.

OBJECTIVE: To prospectively investigate the evolution of the consciousness state and the cannula-weaning progression in patients with prolonged disorders of consciousness. DESIGN: Nonconcurrent cohort study. SETTING: A rehabilitation unit. PARTICIPANTS: Adult patients (N=144) with prolonged disorders of consciousness after a severe acquired brain injury admitted between June 2020 and September 2022. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Consciousness state was assessed by repeated Coma Recovery Scale-Revised (CRS-R) questionnaire administration at admission and weekly afterward. The dates of the first improvement of consciousness state and the achievement of decannulation were recorded. Decannulation followed an internal protocol of multiprofessional rehabilitation. RESULTS: One hundred forty-four patients were included: age, 69 years; 64 (44.4%) with hemorrhagic etiology; time post onset, 40 days, CRS-R score at admission, 9, median length of stay, 90 days. Seventy-three (50.7%) patients were decannulated. They showed a significantly higher CRS-R (P<.001) and states of consciousness (P<.001) at admission, at the first improvement of the consciousness state (P=.003), and at discharge (P<.001); a lower severity in the Cumulative Illness Rating Scale at admission (P=.01); and a lower rate of pulmonary infections with recurrence (P=.021), compared with nondecannulated patients. Almost all decannulated patients (97.3%) improved their consciousness before decannulation. Consciousness states at decannulation were as follows: unresponsive wakefulness syndrome, 0 (0%); minimally conscious state (MCS) minus, 4 (5.5%); MCS plus, 7 (9.6%); and emergence from MCS, 62 (84.9%). Kaplan-Meier analysis showed a significant divergence between the curves with a higher probability of decannulation in patients who improved consciousness (P<.001). CONCLUSIONS: This study showed that the presence of signs of consciousness, even subtle, is a necessary condition for decannulation, suggesting that consciousness may influence some of the components implied in the decannulation process.
RESUMO
OBJECTIVE: To describe the safety, feasibility, and tolerability of overground exoskeleton gait training (OEGT) integrated into clinical practice for patients after severe acquired brain injury (ABI). SETTING: Inpatient rehabilitation hospital. PARTICIPANTS: Eligible patients with severe ABI met the following criteria: age > 18, medically stable, met exoskeleton frame limitations, and a score of ≤ 3 on the motor function portion of the Coma Recovery Scale - Revised (CRS-R). Presence of consciousness disorder was not exclusionary. DESIGN: Prospective observational study. MAIN MEASURES: Outcomes examined safety (adverse events), feasibility (session count and barriers to session completion), and tolerability of OEGT (session metrics and heart rate). RESULTS: Ten patients with ABI completed 10.4 ± 4.8 OEGT sessions with no adverse events. Barriers to session completion included clinical focus on prioritized interventions. Sessions [median up time = 17 minutes, (IQR: 7); walk time = 13 minutes, (IQR: 9); step count = 243, (IQR: 161); device assist = 74, (IQR: 28.0)] were primarily spent in Very Light to Light heart rate intensities [89%, (IQR: 42%) and 9%, (IQR: 33%), respectively]. CONCLUSION: OEGT incorporated into the rehabilitation plan of care during inpatient rehabilitation after severe ABI was observed to be safe, feasible, and tolerable. However, intentional steps must be taken to facilitate patient safety.

BACKGROUND: The objective of this study was to investigate the value of mismatch negativity (MMN) and P300 event-related potentials for discriminating the consciousness state and predicting improvement of consciousness at 6 months in patients with coma and other disorders of consciousness (DOC). METHODS: We performed MMN and P300 on 42 patients with DOC with a mean onset time of 40.21 ± 19.43 days. These patients with DOC were categorized into coma, unresponsive wakefulness syndrome (UWS), minimal consciousness minus (MCS-), and minimal consciousness plus (MCS +) groups according to neurobehavioral assessment and the Coma Recovery Scale-Revised score. The primary outcome was the improvement of consciousness at 6 months in patients with DOC. We assessed the efficacy of MMN and P300 in quantitatively predicting the prognosis at 6 months and the capability of MMN and P300 parameters to differentiate between DOC. RESULTS: At least one significant difference in either MMN or P300 parameters was displayed among the DOC groups, but not between the MCS- and MCS+ groups (significance level: 0.05). Both MMN and P300 amplitudes showed desirable predictive accuracy at 6 months, with areas under the curve (AUCs) of 0.859 and 0.856, respectively. The optimal thresholds for MMN and P300 amplitudes were 2.044 and 1.095 µV. However, the combined MMN-P300 amplitude showed better 6-month predictive accuracy (AUC 0.934, 95% confidence interval 0.860-1.000), with a sensitivity of 85% and a specificity of 90.9%. CONCLUSIONS: MMN and P300 may help discriminate among coma, UWS, and MCS, but not between patients with MCS- and patients with MCS+ . The MMN amplitude, P300 amplitude, and especially combined MMN-P300 amplitude at 6 months may be interesting predictors of consciousness improvement at 6 months in patients with DOC. TRIAL REGISTRATION: Chinese Clinical Trial Registry identifier ChiCTR2400083798.
RESUMO
BACKGROUND AND PURPOSE: The prognosis of prolonged (28 days to 3 months post-onset) disorders of consciousness (pDoC) due to anoxic brain injury is uncertain. The present study aimed to evaluate the long-term outcome of post-anoxic pDoC and identify the possible predictive value of demographic and clinical information. METHOD: This is a systematic review and meta-analysis. The rates of mortality, any improvement in clinical diagnosis, and recovery of full consciousness at least 6 months after severe anoxic brain injury were evaluated. A cross-sectional approach searched for differences in baseline demographic and clinical characteristics between survivors and non-survivors, patients improved versus not improved, and patients who recovered full consciousness versus not recovered. RESULTS: Twenty-seven studies were identified. The pooled rates of mortality, any clinical improvement and recovery of full consciousness were 26%, 26% and 17%, respectively. Younger age, baseline diagnosis of minimally conscious state versus vegetative state/unresponsive wakefulness syndrome, higher Coma Recovery Scale Revised total score, and earlier admission to intensive rehabilitation units were associated with a significantly higher likelihood of survival and clinical improvement. These same variables, except time of admission to rehabilitation, were also associated with recovery of full consciousness. CONCLUSIONS: Patients with anoxic pDoC might improve over time up to full recovery of consciousness and some clinical characteristics can help predict clinical improvement. These new insights could support clinicians and caregivers in the decision-making on patient management.

OBJECTIVE: To examine (1) the concurrent validity of the Music Therapy Assessment Tool for Awareness in Disorders of Consciousness (MATADOC) with the criterion standard Coma Recovery Scale-Revised (CRS-R) for outcomes of awareness in patients with prolonged disorders of consciousness (PDoC), (2) the relationship between MATADOC items and CRS-R function subscales in similar domains, and (3) determine if items/function subscales measure different constructs. DESIGN: A prospective multicentric blinded study with repeated concurrent measures. SETTING: Three inpatient rehabilitation units. PARTICIPANTS: Convenience sample of 74 adults with PDoC (N=74). MAIN OUTCOME MEASURES: The MATADOC protocol elicits behavioral responsiveness using live music in 5 tasks. A total score ranges 0-10 scoring behaviors across 14-items. The CRS-R uses a language-based protocol and scores observed responses ranging from 0-23 in 6 function subscales. Both measures were delivered at 4 concurrent time points over 2 weeks. RESULTS: Fair (κ=0.238, P=.006) ranging to moderate (κ=0.419, P<.001) significant agreement was found between CRS-R and MATADOC diagnostic outcomes. Fair-borderline moderate significant agreement was found for overall diagnostic outcomes across all diagnostic categories (κ=0.397, P=.001). There was moderate significant agreement between measures for motor scores (0.551≤κ≤0.571, P<.001) and visual outcomes (0.192≤κ≤0.415, .001≤P<.005) but no agreement for item/function subscale outcomes assessing auditory responsiveness. Exploratory factor analysis of all items showed 2 factors, suggesting that MATADOC and CRS-R measure the same underlying latent variable (awareness) in different ways and could complement each other for diagnosis and intervention purposes. This was supported by scale analysis, which showed increased reliability when the 2 scales are used together rather than separately. CONCLUSIONS: Unlike the CRS-R, the music-based MATADOC scores auditory localization for complexity of response and categorizes these behaviors as conscious rather than reflexive. The MATADOC may supplement the CRS-R, having a particular role in interdisciplinary programming for providing a more robust assessment of auditory responsiveness because of using nonverbal musical stimuli.

OBJECTIVE: To characterize demographic, pre-injury, and outcome data within the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) and Veterans Affairs (VA) Traumatic Brain Injury Model Systems (TBIMS) cohorts with severe traumatic brain injury (TBI) with no command-following ability at time of admission to acute rehabilitation. DESIGN: Retrospective cohort. SETTING: NIDILRR and VA TBI Model Systems (TBIMS) centers. PARTICIPANTS: 396 NIDILRR and 72 VA participants without command-following ability who experienced TBI with subsequent Disorder of Consciousness (DoC). MAIN OUTCOME MEASURE: Pre-injury and injury characteristics, rehabilitation outcomes, and 1-year self-reported outcomes. RESULTS: VA TBIMS cohort included individuals who were active duty or had military service before their injury. The VA cohort were more likely to be re-hospitalized at 1-year follow-up or residing in a long-term care or rehab setting. The NIDILRR TBIMS cohort had higher FIM and DRS scores at rehabilitation discharge, while the VA participants saw longer lengths of stay and higher numbers of "violent" injury types. CONCLUSIONS: This study allows for a better understanding of the comparability between VA and NIDILRR DoC cohorts providing guidance on how veteran and civilian samples might be merged in future TBIMS studies to explore predictors of recovery from a DoC.

Determining the state of consciousness in patients with disorders of consciousness is a challenging task because for someone to be deemed conscious, both wakefulness and awareness are required. Awareness has traditionally been assessed by examining physical responsiveness but in 2010, Monti et al. explored how using fMRI to measure brain activity in humans could help reclassify the state of consciousness in these patients. The findings, published in The New England Journal of Medicine, show that some brain regions are active when patients respond to an imagery or communication task. This is a seminal study because it demonstrates that patients who behaviourally appear to be in a vegetative or minimally conscious state may still have residual brain functions that would not be apparent from a clinical examination alone. Notably, it exemplified how fMRI can be repurposed as a communication tool for this subset of aware, but 'locked in', patients who appear unresponsive. From an educator's perspective, this paper is valuable because it is relevant to a broad audience, both introductory and advanced level undergraduate students. It introduces key concepts in cognitive and clinical neuroscience and encourages students to consider the connections between social issues and technology development in neuroscience. Finally, educators may use this paper to discuss and debate the nature of consciousness and the ethical implications that the use of fMRI for determining consciousness may have on medical ethics.
RESUMO
BACKGROUND: The purpose of this study was to describe and analyze clinical characteristics and outcomes in children with acute catastrophic brain injury (CBI). METHODS: This was a single-center, 13-year (2008-2020) retrospective cohort study of children in the pediatric and cardiac intensive care units with CBI, defined as (1) acute neurologic injury based on clinical and/or imaging findings, (2) the need for life-sustaining intensive care unit therapies, and (3) death or survival with a Glasgow Coma Scale score < 13 at discharge. Patients were excluded if they were discharged directly to home < 14 days from admission or had a chronic neurologic condition with a baseline Glasgow Coma Scale score < 13. The association between the primary outcome of death and clinical variables was analyzed by using Kaplan-Meier estimates and multivariable Cox proportional hazard models. Outcomes assessed after discharge were technology dependence, neurologic deficits, and Functional Status Score. Improved functional status was defined as a change in total Functional Status Score [Formula: see text] 2. RESULTS: Of 106 patients (58% boys, median age 3.9 years) with CBI, 86 (81%) died. Withdrawal of life-sustaining therapies was the most common cause of death (60 of 86, 70%). In our multivariable analysis, each unit increase in admission pediatric sequential organ failure assessment score was associated with 10% greater hazard of death (hazard ratio 1.10, 95% confidence interval 1.04-1.17, p < .01). After controlling for admission pediatric sequential organ failure assessment scores, compared with those of patients with traumatic brain injury, all other etiologies of CBI were associated with a greater hazard of death (p = .02; hazard ratio 3.76-10). The median survival time for the cohort was 22 days (95% confidence interval 14-37 days). Of 23 survivors to hospital discharge, 20 were still alive after a median of 2 years (interquartile range 1-3 years), 6 of 20 (30%) did not have any technology dependence, 12 of 20 (60%) regained normal levels of alertness and responsiveness, and 15 of 20 (75%) had improved functional status. CONCLUSIONS: Most children with acute CBI died within 1 month of hospitalization. Having traumatic brain injury as the etiology of CBI was associated with greater survival, whereas increased organ dysfunction score on admission was associated with a higher hazard of mortality. Of the survivors, some recovered consciousness and functional status and did not require permanent technology dependence. Larger prospective studies are needed to improve prediction of CBI among critically ill children, understand factors guiding clinician and family decisions on the continuation or withdrawal of life-sustaining treatments, and characterize the natural history and long-term outcomes among CBI survivors.

Our aim was to evaluate the impact of OSF on psychological stress. Ninety OSF cases and age and sex-matched controls, enrolled from relatives or accompanying person were included in the study. Psychological stress was evaluated by the Psychological General Well Being Index short version (PGWBI-S). Sets of the psychological component were generated by principal component analysis (PCA). Association between components was accommodated for confounder and interaction was evaluated by conditional stepwise logistic regression analysis. Psychological component generated was component 1 (depressed mood, lack of positive well being, low vitality, anxiety, low vitality, and low self-control). The odds ratio (OR) of low score of component 1 for OSF was 3.66. Depressed mood, lack of positive well being, low vitality, anxiety, low vitality, and low self-control were associated with OSF. Psychological intervention should, therefore, be included in the management of OSF.

OBJECTIVES: To examine the construct validity and measurement precision of the Coma Near-Coma scale (CNC) in measuring neurobehavioral function (NBF) in patients with disorders of consciousness receiving postacute care rehabilitation. DESIGN: Rasch analysis of retrospective data. PARTICIPANTS: Participants (N=48) with disordered consciousness who were admitted to postacute care rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: CNC. RESULTS: Assessment with CNC repeated weekly until the participant was conscious or discharged from the postacute care facility (451 participant records). Rating scale steps were ordered for all items. Eight of the 10 CNC items evaluated in this study fit the measurement model (χ2=5332.58; df=11; P=.17); pain items formed a distinct construct. The ordering of the 8 items from most to least challenging makes clinical sense and compares favorably with other published hierarchies of NBF. Tactile items are more easily responded to. Visual and auditory items requiring higher cognitive processing were more challenging. In the full sample, the CNC achieved good measurement precision, with a person separation reliability of 0.87. CONCLUSIONS: The items of the CNC reflect good construct validity and acceptable interrater reliability. The measurement precision achieved indicates that the CNC may be used to make decisions about groups of individuals but that these items may not be sufficiently precise for individual patient treatment decision-making.

OBJECTIVES: To investigate functional outcomes and state of consciousness at 1 year and ≥2 years postinjury in children who sustained a traumatic brain injury and were in a disorder of consciousness (DOC), either vegetative state (VS) or minimally conscious state (MCS), upon admission to inpatient rehabilitation. DESIGN: Retrospective chart review. SETTING: Pediatric inpatient rehabilitation unit. PARTICIPANTS: Children aged 2-18 years (N=37) who were admitted to inpatient rehabilitation with admission scores <30 on the Cognitive and Linguistic Scale (CALS). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Glasgow Outcome Scale- Extended, Pediatric Revision (GOS-E Peds), and state of consciousness based on previously established guidelines. RESULTS: At admission, 16 children were in VS (43.2%) and 21 (56.8%) were in MCS. Children admitted in VS had a significantly longer time from injury to inpatient rehabilitation admission, lower CALS admission scores, were more likely to be in a DOC ≥28 days, and had greater disability at both follow-up time points. At the 1-year follow-up, 3 patients were in VS, 7 were in MCS, and 27 had emerged from MCS. By the time of the most recent follow-up (≥2y), 2 more patients had emerged from MCS. Across the cohort, GOS-E Peds scores at 1 year ranged from VS (GOS-E Peds, 7) to upper moderate disability (GOS-E Peds, 3). Most patients were functioning in the lower severe disability category (GOS-E Peds, 6) at 1 year (43.2%) and at the time of the most recent follow-up (43.2%). Twenty-seven patients (73.0%) showed stable GOS-E Peds scores between the 2 time points, 6 (16.2%) improved, and 4 (10.8%) were deceased. CONCLUSIONS: Although a majority of patients emerged from a DOC by 1 year postinjury, most continued to demonstrate notable functional impairment at the 1-year follow-up that persisted to the most recent follow-up. A small subset demonstrated important improvements between 1 year and the most recent follow-up (2 patients emerged, 6 patients showed improvement in GOS-E Peds scores).

BACKGROUND: We investigated the clinical course of patients with prolonged disorders of consciousness (PDoC), predictors of emergence from PDoC (EDoC), and the temporal dynamics of six neurobehavior domains based on the JFK Coma Recovery Scale-Revised (CRS-R) during the recovery. METHODS: A total of 50 traumatic and non-traumatic patients with PDoC were enrolled between October 2014 and February 2017. A retrospective analysis of the clinical findings and neurobehavioral signs was conducted using standardized methodology such as CRS-R. The findings were used to investigate the incidence and predictors of EDoC and determine the cumulative pattern of neurobehavioral recovery at 6 months, 1 year, and 2 years post-injury. RESULTS: The results showed that 46% of the subjects emerged from PDoC after 200 median days (64-1197 days) of injury onset. The significant predictors of EDoC included minimally conscious state (MCS) (vs. vegetative state), higher auditory, communication, arousal, total CRS-R scores, shorter lag time post-injury, and the absence of intra-axial lesions. In terms of cumulative recovery of motor and communication signs in patients who emerged from PDoC, 39 and 32% showed EDoC at 6 months post-injury, and 88 and 93% exhibited EDoC at 2 years post-injury, respectively. CONCLUSIONS: Nearly half of the patients with PDoC recovered consciousness during inpatient rehabilitation. MCS, shorter lag time, the absence of intra-axial lesions, higher auditory, communication, arousal, and total CRS-R scores were important predictors for EDoC. Motor scores in the early stage of recovery and communication scores after prolonged intervals contributed to the higher levels of cumulative EDoC.

OBJECTIVE: To identify the effect of some clinical characteristics of severe acquired brain injury (sABI) patients on decannulation success during their intensive rehabilitation unit (IRU) stay. DESIGN: Nonconcurrent cohort study. SETTING: Don Gnocchi Foundation Institute. PARTICIPANTS: Patients (N=351) with sABI and tracheostomy were retrospectively selected from the database of the IRU of the Don Gnocchi Foundation Institute. MAIN OUTCOME MEASURES: Potential predictors of decannulation were screened from variables collected at admission during clinical examination, conducted by trained and experienced examiners. The association between clinical characteristics and decannulation status was investigated through a Cox regression model. Kaplan-Meier curves were then created for time-event analysis. RESULTS: Among the patients (mean age, 64.1±15.5y), 54.1% were decannulated during their IRU stay. Absence of pulmonary infections (P<.001), sepsis (P=.001), tracheal alteration at the fibrobronchoscopy examination (P=.004) and a higher Coma Recovery Scale-Revised (CRS-R) score (P<.001) or a better state of consciousness at admission (P=.001) were associated with a higher probability of decannulation. CONCLUSIONS: Fibrobronchoscopy assessment of patency of airways and accurate evaluation of the state of consciousness using the CRS-R are relevant in this setting of care to better identify patients who are more likely to have the tracheostomy tube removed. These results may help clinicians choose the appropriate timing and intensity of rehabilitation interventions and plan for discharge.

OBJECTIVE: Characterize the temporal profile of recovery of communication after severe brain injury. DESIGN: Retrospective cohort study. SETTING: Inpatient rehabilitation hospital. PARTICIPANTS: Patients with severe acquired brain injury and no evidence of communication on the Coma Recovery Scale-Revised (CRS-R) (N=175). MAIN OUTCOME MEASURES: Time from injury to recovery of intentional communication (IC, inconsistent yes/no responses) and functional communication (FC, consistent and accurate yes/no responses) on the CRS-R Communication subscale. RESULTS: Patients (N=175) were included in the primary observation period of the first 8 weeks of inpatient rehabilitation (median [interquartile range, IQR]: 48 [27-61] years old, 105 men, 28 [21-38] days postinjury, 100 traumatic etiology). Fifty-four patients (31%) did not recover IC or FC. Thirty patients (17%) recovered IC only (median [IQR] days from injury to IC= 40 [34-54]), 72 patients (41%) recovered IC followed by FC (days from injury to FC=50 [42-61]), and 19 patients (11%) recovered FC without first recovering IC (43 [32-63]). The patients who recovered neither IC nor FC within 8 weeks of admission were admitted to rehabilitation later than those who recovered IC and/or FC (P<.01). Sixteen patients who did not recover communication within 8 weeks of admission to rehabilitation subsequently recovered FC prior to discharge. CONCLUSIONS: In patients with severe brain injury receiving inpatient rehabilitation, discernible yes-no responses emerged approximately 6 weeks postinjury and became reliable 1 week later. Approximately 1 in 3 patients did not demonstrate IC or FC within 8 weeks of admission to rehabilitation, although 33% of these individuals recovered communication prior to discharge. In total, 61% of patients recovered FC prior to discharge from rehabilitation.

Aims: To develop a structured goal-set for use in programs for the assessment and management of prolonged disorders of consciousness (PDOC).Methods: A retrospective analysis of goals from a consecutive cohort of patients (n = 162) admitted to a specialist in-patient PDOC program in the UK from 2007 to 2018. Overall goal attainment was examined with Goal Attainment Scaling (GAS) using the GAS-Light method. Rates of individual goal-setting and achievement were examined for both standardized objectives (n = 2959) and personalized goals (n = 661). Goal statements from the personalized goals were independently reviewed and mapped to the domains of the existing structured objective set to identify any missing goal areas.Results: Mean outcome GAS T-scores were 47.2 (95% CI: 46.7, 47.6) and 47.7 (95% CI: 46.7, 48.8), respectively, for the standardized and personally set goals. These were closely correlated (r = 0.482, p < .001) with no significant difference between them. Analysis of goal achievement within each domain identified goals that were/were not likely to be achieved. An initial structured set of 20 standardized objectives in 12 domains was expanded and re-organized to produce a final-structured goal-set of 36 objectives in 18 domains.Conclusions: Developed through real-life clinical practice, this first published structured goal-set for PDOC programs now requires testing in other services/settings.

OBJECTIVES: To investigate behavioral and demographic features of levels of consciousness in young children with brain injury, including the classifications of consciousness: conscious state (CS), minimally conscious state (MCS), and vegetative state (VS), and to investigate the course of recovery in children with disorders of consciousness (DOC). DESIGN: Retrospective chart review and post hoc analysis. SETTING: Pediatric inpatient rehabilitation unit. PARTICIPANTS: Children aged 6 months to 5 years (N=54) admitted for inpatient rehabilitation directly from an acute care hospital following new neurologic injury from 2011 to 2016. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Clinically abstracted behavioral features of DOC and levels of consciousness at admission and discharge, based on established guidelines from the Aspen Neurobehavioral Conference Workgroup. RESULTS: Children in MCS were younger than children in CS. Commonly observed behaviors in children in VS were mouth movements or vocalizations, flexion withdrawal or motor posturing, visual or auditory startle, and localization to sound. Common features of MCS were contingent affect, visual fixation or pursuit, automatic motor behavior, and contingent communicative intent. No children in MCS showed command following or intelligible verbalizations. All children in CS showed functional object use, while functional communication was observed in a subset. By discharge, more than half of children in VS emerged to MCS, and a third emerged from MCS to CS. No child emerged from VS to CS. CONCLUSIONS: Visual and motor skills may be most applicable, and language-based skills may be least applicable for the assessment of DOC in very young children. Accurate classifications of consciousness may have important prognostic implications, and additional research is needed to develop clear guidelines for assessment of DOC in this population.

OBJECTIVES: To investigate the relation between consciousness and nociceptive responsiveness (ie, Nociception Coma Scale-Revised [NCS-R]), to examine the suitability of the NCS-R for assessing nociception in participants with disorders of consciousness (DOC), and to replicate previous findings on psychometric properties of the scale. DESIGN: Specialized DOC program. SETTING: Specialized DOC program and university hospitals. PARTICIPANTS: Participants (N=85) diagnosed with DOC. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: We prospectively assessed consciousness with the Coma Recovery Scale-Revised (CRS-R). Responses during baseline, non-noxious, and noxious stimulations were scored with the NCS-R and CRS-R oromotor and motor subscales. RESULTS: CRS-R total scores correlated with NCS-R total scores and subscores. CRS-R motor subscores correlated with NCS-R total scores and motor subscores, and CRS-R oromotor subscores correlated with NCS-R total scores as well as verbal and facial expression subscores. There was a difference between unresponsive wakefulness syndrome and minimally conscious state in the proportion of grimacing and/or crying participants during noxious conditions. We replicated previous findings on psychometric properties of the scale but found a different score as the best threshold for nociception. CONCLUSIONS: We report a strong relation between the responsiveness to nociception and the level of consciousness. The NCS-R seems to be a valuable tool for assessing nociception in an efficient manner, but additional studies are needed to allow recommendations for clinical assessment of subjective pain experience.

BACKGROUND: In palliative care, administration of opioids is often indispensable for pain treatment. Pain assessment may help recognize pain and guide treatment in non-communicative patients. In the Netherlands the Rotterdam Elderly Pain Observation Scale (REPOS) is recommended to this aim, but not yet validated. Therefore the objective of this study was to validate the REPOS in non-communicative or unconscious end-of-life patients. METHODS: In this observational study, the primary researcher applied the REPOS, while both the researcher and a nurse applied the Numeric Rating Scale (NRS). If possible, the patient in question applied the NRS as well. The NRS scores were compared with the REPOS scores to determine concurrent validity. REPOS scores obtained before and after a pain-reducing intervention were analysed to establish the scale's sensitivity to change. RESULTS: A total of 183 REPOS observations in 100 patients were analysed. Almost 90% of patients had an advanced malignancy; observations were done a median of 3 days (IQR 1 to 13) before death. Internal consistency of the REPOS was 0.73. The Pearson product moment correlation coefficient ranged from 0.64 to 0.80 between REPOS and NRS scores. REPOS scores declined with median 2 points (IQR 1 to 4) after a pain-reducing intervention (p < 0.001). Optimal sensitivity (0.81) and specificity (0.62) were found at cut-off score 3. CONCLUSIONS: This study demonstrates that the REPOS has promising psychometric properties for pain assessment in non-communicative end-of-life patients. Its application may be of additional value to relieve suffering, including pain, in palliative care.
