Participation 1.5 years after mild traumatic brain injury in children and adolescents.

This longitudinal prospective cohort study examined participation between 6 months and 1.5 years after pediatric mild Traumatic Brain Injury (mTBI) in 68 children aged 6-18 years. Levels of participation in different settings remain mostly stable between 6 months and 1.5 years after mTBI, with a substantial proportion of children continuing to indicate less than full functioning. Future studies should examine risk factors and opportunities for early identification to prevent long-term negative consequences of pediatric mTBI regarding participation.

Case management for people with acquired brain injury: feasibility and effectiveness of a two-year pragmatic randomized controlled trial.

BACKGROUND: Case management (CM) aims to facilitate access to and integration of health care and social services. We investigated the feasibility and effectiveness of CM. METHODS: Randomized controlled trial with 219 patients and 114 caregivers randomly allocated to CM (109/59) or care as usual (110/55). CM was based on early and continuous online monitoring of problems and needs. Outcomes were assessed every 6 months with the Hospital Anxiety and Depression Scale (HADS). Secondary outcome domains were participant restrictions, life satisfaction, self-efficacy, caregiver burden, and needs. Multilevel modeling was used. Feasibility aspects were protocol delivery, participants' and case managers' satisfaction, and factors affecting implementation. RESULTS: There were no significant differences between groups. Participation restrictions and unmet needs decreased in both groups within 6 months. Monitoring was successful in 38, and 10 participants asked the CM for support. CM consisted mostly of providing information. DISCUSSION: CM based on early and continuous online monitoring does not have benefit in identifying and addressing problems early after relatively mild injury. Unsuccessful monitoring may have hindered access to the case manager and prevented us from evaluating CM as a complex intervention. It remains a challenge to early identify those who could benefit from care coordination.

Long term functioning with poor neurologic outcome after cardiac arrest.

AIM: Around six percent of comatose patients after cardiac arrest have a Cerebral Performance Categories score of three (CPC3) at six months after the arrest, classified as severe neurological disability. There is limited knowledge regarding the likelihood of further recovery in the cognitive, emotional, and quality of life domains. We aimed to estimate the probability of recovery towards independency. METHODS: From a prospective Registry on comatose cardiac arrest patients admitted between 2013 and 2017 in two Dutch hospitals, we included patients with a CPC3 at six months after cardiac arrest. We followed patients up to November 2023. The primary outcome measure was the CPC score at time of follow up. Secondary outcomes were scores on questionnaires on cognition, mood, and quality of life according to the minimal dataset of acquired brain injury. RESULTS: In our cohort of 667 patients, 29 (4.3%) had a CPC3 score at six months (median age 68 years, 83% male). At a median time of eight years after cardiac arrest, sixteen patients had died. Twelve of thirteen alive patients still had a CPC3 score (92%) and one a CPC2 (8%). Seven patients agreed with further interviewing, one showed independency in activities of daily living (14%). Six patients (86%) reported limitations due to physical and one (14%) due to emotional problems. All had severe cognitive impairment. Six (86%) missed cognitive rehabilitation. CONCLUSION: Our study shows that while the probability of recovery towards independence for patients with severe neurological disability at six months after cardiac arrest is limited, most long-term survivors are satisfied with their quality of life.

Prevalence and predictors of persistent cognitive and psychological symptoms in non-hospitalized post-COVID-19 patients seeking care at an outpatient post-COVID-19 clinic.

Introduction: There is still much uncertainty about why some people develop persistent cognitive and mental health problems after SARS-CoV-2 infection and require additional care while others do not. In this study, we investigated the cognitive and psychological outcomes of non-hospitalized post-COVID-19 patients referred to an outpatient post-COVID-19 clinic for persistent symptoms more than 3 months after infection. Additionally, we aimed to explore the influence of demographic, physical, and personal factors on these outcomes. Methods: This cross-sectional study was conducted at an outpatient post-COVID-19 clinic located at a prominent clinical teaching hospital in the Netherlands. Participants included non-hospitalized patients referred between 2020 and 2022, more than 3 months after SARS-CoV-2 infection, experiencing persistent symptoms. Main outcome measures included levels of anxiety and depression (Hospital Anxiety and Depression Scale), post-traumatic stress symptoms (PTSS) (Post-traumatic Stress Symptoms Checklist 14), and cognitive symptoms (Checklist for Cognitive and Emotional Consequences). Data analysis employed Spearman correlation and hierarchical multiple regression analyses. Results: A total of 265 patients (61% female; mean age of 51.7 ± 13.7 years) were included in the study, with an average of 7.6 ± 4.5 months following SARS-CoV-2 infection. Among them, 104 patients (40%) reported high levels of anxiety, 111 patients (43%) showed high levels depressive symptoms, and 71 patients (31%) demonstrated high levels of PTSS. Additionally, 200 patients (79%) reported experiencing more than 2 cognitive symptoms. Bivariate analyses indicated associations between psychiatric history and increased cognitive and psychological symptoms. Multivariate analyses revealed positive associations between physical symptoms and cognitive and psychological symptoms, and catastrophizing thoughts were associated with higher anxiety levels (ß = 0.217, p < 0.001). Conversely, positive refocusing was associated with lower depressive symptoms (ß = -0.325, p < 0.001), PTSS (ß = -0.290, p < 0.001), and cognitive symptoms (ß = -0.220, p < 0.001). Discussion: Among non-hospitalized COVID-19 patients seeking care for persistent symptoms, approximately one-third reported high levels of psychological symptoms, and more than three-quarter experienced cognitive symptoms. Physical symptoms, psychiatric history, and a tendency to catastrophize were identified as potential risk factors for persistent psychological and cognitive symptoms. Conversely, positive refocusing demonstrated a protective effect. These findings contribute to the understanding of long-term COVID-19 outcomes and emphasize the importance of integrating a biopsychosocial perspective into treatment approaches.

The Role of Cognition, Affective Symptoms, and Apathy in Treatment Adherence with Noninvasive Home Mechanical Ventilation in Myotonic Dystrophy.

Background: Chronic respiratory failure often occurs in myotonic dystrophy type 1 (DM1) and can be treated with noninvasive home mechanical ventilation (HMV). Treatment adherence with HMV is often suboptimal in patients with DM1, but the reasons for that are not well understood. Objective: The aim of this exploratory study was to gain insight in the prevalence of mild cognitive impairment, affective symptoms, and apathy and to investigate their role in HMV treatment adherence in DM1. Methods: The Montreal Cognitive Assessment (MoCA), the Hospital Anxiety and Depression Scale (HADS), and the Apathy Evaluation Scale (AES) were used to assess cognition, affective symptoms, and apathy in DM1 patients that use HMV. Patients with low treatment adherence (average daily use HMV <5 h or <80% of the days) were compared with patients with high treatment adherence (average daily use of HMV≥5 h and ≥80% of the days). Results: Sixty patients were included. Abnormal scores were found in 40% of the total group for the MoCA, in 72-77% for the AES, and in 18% for HADS depression. There was no difference between the high treatment adherence group (n = 39) and the low treatment adherence group (n = 21) for the MoCA, AES, and HADS depression. The HADS anxiety was abnormal in 30% of the total group, and was significantly higher in the low treatment adherence group (p = 0.012). Logistic regression analysis revealed that a higher age and a higher BMI were associated with a greater chance of high treatment adherence. Conclusions: This exploratory study showed that cognitive impairment and apathy are frequently present in DM1 patients that use HMV, but they are not associated with treatment adherence. Feelings of anxiety were associated with low treatment adherence. Higher age and higher BMI were associated with high treatment adherence with HMV.

Neuropsychological functioning after COVID-19: minor differences between individuals with and without persistent complaints after SARS-CoV-2 infection.

Objective: It is unclear how self-reported severe fatigue and difficulty concentrating after SARS-CoV-2 infection relate to objective neuropsychological functioning. The study aimed to compare neuropsychological functioning between individuals with and without these persistent subjective complaints. Method: Individuals with and without persistent severe fatigue (Checklist Individual Strength (CIS) fatigue ≥ 35) and difficulty concentrating (CIS concentration ≥ 18) at least 3 months after SARS-CoV-2 infection were included. Neuropsychological assessment was performed on overall cognitive functioning, attention, processing speed, executive functioning, memory, visuo-construction, and language (18 tests). T-scores -1.5 SD below population normative data (T ≤ 35) were classified as "impaired". Results: 230 participants were included in the study, of whom 22 were excluded from the analysis due to invalid performance. Of the participants included in the analysis, 111 reported persistent complaints of severe fatigue and difficulty concentrating and 97 did not. Median age was 54 years, 59% (n = 126) were female, and participants were assessed a median of 23 months after first infection (IQR: 16-28). With bivariate logistic regression, individuals with persistent complaints had an increased likelihood of slower information processing speed performance on the Stroop word reading (OR = 2.45, 95%CI = 1.02-5.84) compared to those without persistent complaints. Demographic or clinical covariates (e.g. hospitalization) did not influence this association. With linear regression techniques, persistent complaints were associated with lower t-scores on the D2 CP, TMT B, and TMT B|A. There were no differences in performance on the other neuropsychological tests. Conclusions: Individuals with subjective severe fatigue and difficulty concentrating after COVID-19 do not typically demonstrate cognitive impairment on extensive neuropsychological testing.

Young children's performance on a design fluency task: longitudinal data on total number of designs, clustering and switching, and regression-based norms.

INTRODUCTION: Design fluency (DF) tasks are commonly used to assess executive functions such as attentional control, cognitive flexibility, self-monitoring and strategy use. Next to the total number of correct designs, the standard outcome of a DF task, clustering and switching can help disentangle the processes underlying DF performance. We present the first longitudinal study of 4-8-year-old children's developmental DF trajectories. METHOD: At initial enrollment, children (n = 228) were aged between 4.05 and 6.88 years (M = 5.18, SD = 0.59) and attended Dutch primary schools. The DF task was administered at three time points, each time point separated by approximately 1 year. Data were analyzed using mixed regression for total number of correct designs and switching, and mixed logistic regression analysis for clustering. RESULTS: The total number of correct designs increased linearly across the three time points. Across all time points, children made very few clusters, and most clusters consisted of only 3 designs. Clustering only increased at the third assessment compared to the two previous assessments. Switching increased up to the second assessment, but not after that. The number of switches was highly correlated with the total number of correct designs at all time points (r = 0.78 to r = 0.85). These developmental trajectories were similar for all children regardless of their baseline age. Normative data are given for the total number of correct designs and switching. CONCLUSIONS: Children as of age 4 onwards can perform a DF task. For children as young as 4-8 years old, computing clustering, and switching measures is of limited value to study cognitive processes underlying DF performance, next to the total number of correct designs. There were no sex differences on any of the DF outcomes. Level of parental education (LPE) was positively associated with the total number of correct designs and switching.

Factors Related to the Quality and Stability of Partner Relationships After Stroke: A Systematic Literature Review.

OBJECTIVE: To provide an overview of the current state of knowledge on factors related to relationship quality and relationship stability after stroke. DATA SOURCES: Cumulative Index to Nursing and Allied Health (CINAHL), Embase, MEDLINE, Psychology and Behavioral Sciences Collection, APA PsycINFO, and PubMed were searched on November 15, 2022, for literature on factors associated with (1) relation quality and (2) relation stability after stroke. STUDY SELECTION: English quantitative and qualitative studies investigating factors associated with relation quality and/or stability after stroke were included. Three reviewers independently assessed eligibility. Consensus meetings were held in case of divergent opinions. A total of 44 studies were included. DATA EXTRACTION: Information regarding study objectives and characteristics, participant demographics, independent and dependent variables, and main findings was extracted. Study quality was rated using the Joanna Briggs Institute Checklist for Analytical Cross-Sectional Studies and/or the Critical Appraisal Skills Programme Checklist for Qualitative Research. Both were administered by the lead reviewer and checked by the second reviewer. Identified factors are described and presented according to the domains of the International Classification of Functioning, Disability, and Health model. DATA SYNTHESIS: Thirty-seven factors related to relationship quality after stroke were identified, covering the domains of body functions and structures (eg, cognitive problems), activities (eg, decrease in physical intimacy), participation (eg, being socially active), environment (eg, medication side effects), and personal factors (eg, hypervigilance). Eight factors related to relationship stability were identified, covering the domains of participation (agreement on reciprocal roles) and personal factors (eg, quality of prestroke relation). CONCLUSIONS: Relationship quality and stability after stroke are related to a multitude of factors. Future research should confirm the relevance of factors found in a few studies of suboptimal quality; explore possible associations between relationship stability and factors falling in the domains of body functions and structure, activity, and environmental factors; and explicitly explore potential positive effects of stroke on relationships.

Psychometric properties of two instruments assessing catastrophizing and fear-avoidance behavior in mild traumatic brain injury.

OBJECTIVE: Psychometrically sound measures of catastrophizing about symptoms and fear avoidance behavior are needed to further applications of the fear-avoidance model in mild traumatic brain injury (mTBI) for research and clinical purposes. To this end, two questionnaires were adapted (minor), the Postconcussion Symptom Catastrophizing Scale (PCS-CS) and the Fear of Mental Activity Scale (FMA). This study aimed to investigate the factor structure, internal consistency, test-retest reliability, and concurrent and construct validity of two adapted questionnaires in a sample of participants with mTBI compared to participants with orthopedic injury and healthy adults. METHOD: One hundred eighty-five mTBI participants (40% female), 180 participants with orthopedic injury (55% female), and 116 healthy adults (55% female) participated in the study. All participants were assessed at two time points (2 weeks postinjury and 3 months) using self-reported questionnaires. Data were collected using online questionnaires. RESULTS: Findings indicated a three-factor model (magnification, rumination, helplessness) with a higher order factor (catastrophizing) for the PCS-CS and a two-factor model (activity avoidance and somatic focus) for the FMA. The results showed strong internal consistency, good test-retest reliability, and good concurrent and convergent validity for the PCS-CS and FMA across all samples. CONCLUSIONS: This study has shown that the PCS-CS and FMA are psychometrically sound instruments and can be considered for valid and reliable assessment of catastrophizing about postconcussion like symptoms and fear-avoidance beliefs about mental activities. These instruments can be used in research and clinical practice applications of the fear-avoidance model and add to explanations of prolonged recovery after mTBI.

Socratic guided feedback therapy after acquired brain injury: A multicenter randomized controlled trial to evaluate effects on self-awareness.

Impaired self-awareness after acquired brain injury (ABI) challenges neuropsychological rehabilitation. The current study aimed to compare the effects of Socratic Guided Feedback therapy to usual care in a multicenter randomized controlled trial with 64 participants with reduced self-awareness after ABI. The objectives were to study the effects on (1) self-awareness and (2) motivation for and participation in therapy, mood, quality of life, and social participation. Patients were recruited from rehabilitation centres in The Netherlands and Belgium. They were 50.8 (±16) years old and 2.7 months (±1.8) post-injury at baseline. Session duration ranged from 20-60 minutes and the number of sessions ranged from 1 to 162 sessions. Self-awareness increased over time in both groups. Between 9 and 12 months after baseline measurement, self-awareness (Patient Competency Rating Scale discrepancy score between patient and significant other) improved in the experimental group and deteriorated in care as usual. No significant differences were found on secondary outcome measures. In conclusion, Socratic Guided Feedback therapy is as effective as care as usual but provides a structure for therapists. We recommend further investigation of the added value of Socratic Guided Feedback therapy in later follow-up measurements, group therapy settings, and on other outcome domains such as caregiver burden.

Development and content validity of the cognition in daily life scale (CDL).

Cognitive impairment can negatively influence daily functioning. Current cognitive measures are essential for diagnosing cognitive impairment, but findings on these tests do not always represent the level of cognitive functioning in daily life. Therefore, this study aimed to design a structured measurement instrument to observe and rate the impact of cognitive impairment in daily life, named the cognition in daily life scale for persons with cognitive problems (CDL). In this paper we describe the development, expected usability, and psychometric properties (content and face validity) of the instrument. The CDL was established through three consecutive development phases: (1) item selection, (2) item categorization and comparison, and (3) item revision and manual construction. Subsequently, a panel of eleven international experts rated the relevance of the selected items and provided comments on the expected usability and face validity. Content validity was estimated with the content validity index, based on which four items were removed. The experts' comments led to minor adjustments of the manual, domains, and formulation of the maintained items. The final instrument consists of 65 items describing behaviour that relies on cognitive functions within six domains. Future research should focus on evaluating the construct validity and reliability of the CDL.

The Montreal Cognitive Assessment detects cognitive deficits that go unnoticed during clinical observation in the acute phase after stroke.

BACKGROUND: Detecting cognitive impairments early after stroke is essential for appropriate referrals. Although recommended in stroke guidelines, early cognitive screening is not always implemented. We assessed whether the Montreal Cognitive Assessment (MoCA) adds diagnostic value compared to clinical observation alone. In addition, discharge destinations for stroke patients with and without cognitive deficits detected with the screening tool or the treatment team were explored. METHODS: Forty-four stroke patients were screened with the MoCA during stroke unit admission. Their charts were studied for cognitive impairments reported by the stroke care team, who were blinded to screening scores. Proportions of detected cognitive deficits were compared between screening (score <26) and patient charts. Discharge destination distribution (home vs. rehabilitation) was explored. RESULTS: The proportion of cognitively impaired patients indicated by the MoCA (84%) and reported in patients' charts (25%) differed significantly (p < 0.001). The distribution of discharge destination did not suggest an association with the detection of cognitive deficits by the treatment team or the cognitive screening. CONCLUSIONS: The MoCA detects more cognitive deficits than clinical impression alone, emphasizing the importance of standard screening for cognitive impairments in acute stroke patients. Ultimately, systematic screening may enhance discharge planning and improve long-term outcomes.

Prevalence and trajectories of neuropsychological post-COVID-19 symptoms in initially hospitalized patients.

OBJECTIVE: To investigate the prevalence and trajectories of post-COVID-19 neuropsychological symptoms. DESIGN: Prospective longitudinal multicentre cohort study. SUBJECTS: A total of 205 patients initially hospitalized with SARS-CoV-2 (COVID-19). METHODS: Validated questionnaires were administered at 9 months (T1) and 15 months (T2) post-hospital discharge to assess fatigue, cognitive complaints, insomnia, anxiety, depression, and post-traumatic stress symptoms. RESULTS: Analyses included 184 out of 205 patients. Approximately 50% experienced high cognitive complaints at T1 and T2, while severe fatigue affected 52.5% at T1 and 55.6% at T2. Clinically relevant insomnia scores were observed in 25% of patients at both time-points. Clinically relevant anxiety scores were present in 18.3% at T1 and 16.7% at T2, depression in 15.0% at T1 and 18.9% at T2, and PTSD in 12.4% at T1 and 11.8% at T2. Most symptoms remained stable, with 59.2% of patients experiencing at least 1 persistent symptom. In addition, 31.5% of patients developed delayed-onset symptoms. CONCLUSION: Post-COVID-19 cognitive complaints and fatigue are highly prevalent and often persist. A subgroup develops delayed symptoms. Emotional distress is limited. Screening can help identify most patients experiencing long-term problems. Future research should determine risk factors for persistent and delayed onset symptoms.

Trajectories of fatigue and related outcomes following mild acquired brain injury: a multivariate latent class growth analysis.

OBJECTIVE: Fatigue is a common symptom following acquired brain injury although the severity and course differs for many individuals. This longitudinal study aimed to identify latent trajectory classes of fatigue and associated outcomes following mild brain injury. METHODS: 204 adults with mild traumatic brain injury (159; 78%) or minor stroke (45; 22%) were assessed 4 times over 1 year. Subjective measures of fatigue, anxiety, depression, cognitive complaints and societal participation were collected. Multivariate Latent Class Growth Analysis identified classes of participants with similar longitudinal patterns. Demographic and injury characteristics were used to predict class membership. RESULTS: Analysis revealed four classes. Class 1 (53%) had mild, decreasing fatigue with no other problems. Class 2 (29%) experienced high persistent fatigue, moderate cognitive complaints and societal participation problems. Class 3 (11%) had high persistent fatigue with anxiety, depression, cognitive complaints and participation problems. Class 4 (7%) experienced decreasing fatigue with anxiety and depression but no cognitive or participation problems. Women and older individuals were more likely to be in class 2. CONCLUSION: Half the participants had a favourable outcome while the remaining classes were characterised by persistent fatigue with cognitive complaints (class 2), decreasing fatigue with mood problems (class 4) or fatigue with both cognitive and mood problems (class 3). Fatigue treatment should target combinations of problems in such individual trajectories after mild brain injury.

Efficacy of an Intensive Exposure Intervention for Individuals With Persistent Concussion Symptoms Following Concussion: A Concurrent Multiple Baseline Single-Case Experimental Design (SCED) Study.

OBJECTIVE: After a concussion, 1 in 3 patients report persistent symptoms and experience long-term consequences interfering with daily functioning, known as persistent concussion symptoms (PCS). Evidence suggests PCS is (partly) maintained by anxious thoughts about brain functioning, recovery, and experienced symptoms, leading to avoidance behaviors, which may prevent patients from meeting life demands. We aimed to investigate the efficacy of a newly developed intensive exposure intervention for individuals with PCS after concussion aimed to tackle avoidance behavior. SETTING: Participants took part in the intervention at the Maastricht University faculty. PARTICIPANTS: Four participants who experienced PCS after concussion partook in the exploratory study. Participants' age ranged between 20 and 32 (mean = 26.5, SD = 5.9) years, with an average length of time after the concussion of 9.8 months. DESIGN: A concurrent multiple-baseline single-case design was conducted. The baseline period (A phase) length was randomly determined across participants (3, 4, 5, or 6 weeks). The exposure intervention (B phase) was conducted by psychologists over a 4-week period and consisted of 3 stages: exploration (2 sessions), active exposure (12 sessions conducted over 1 week), and 2 booster sessions. MAIN MEASURES: Participants answered daily questions on a visual analog scale related to symptom experience, satisfaction with daily functioning, and degree of avoidance of feared activities. Additional outcomes included symptom severity, catastrophizing, fear of mental activity, anxiety, depression, and societal participation. RESULTS: Tau-U yielded significant effects ( P < .05) for all participants on all measures when comparing baseline and intervention phases. The pooled standardized mean difference was high for all measures (symptom experience = 0.93, satisfaction of daily functioning = 1.86, and activity avoidance = -2.05). CONCLUSIONS: The results show efficacy of the newly developed intensive exposure treatment for PCS after concussion, which is based on the fear avoidance model. Replication in a larger heterogeneous sample is warranted and needed.

Feasibility of a novel blended-care intervention for fatigue after acquired brain injury: a pilot study of the Tied by Tiredness intervention.

PURPOSE: Evidence-based treatments for fatigue after brain injury are scarce and often not personalized. An approach to foster personalization is Experience Sampling Methodology (ESM), consisting of repeated daily measurements of fatigue and related factors in daily life. We investigated the feasibility and usability of a novel six-week ESM-based intervention for fatigue after brain injury. MATERIALS AND METHODS: Ten individuals with acquired brain injury (six men; four women) aged between 36-70 years (M = 53.3, SD = 12.9) used a mHealth application for three days each week during six-weeks; seven completed the intervention. Momentary fatigue, activities, mood, worrying, and social context were assessed with ESM and participants received weekly personalized feedback by a therapist.. RESULTS: 56% of ESM-questionnaires (568/1008) were completed, providing detailed insights into individual fatigue patterns. No statistically significant decrease in response rate was found over the course of treatment. Qualitative feedback from participants revealed increased insight into factors underlying fatigue, and no problems with treatment duration or difficulties using the app. Five participants showed a decline in fatigue level during treatment. CONCLUSIONS: This pilot study provides initial support for the feasibility and usability of this novel blended-care intervention, aimed at alleviating fatigue through personalized feedback and treatment strategies.

Does cognitive learning potential measured with the dynamic Wisconsin Card Sorting Test predict rehabilitation outcome in elderly patients post-stroke?

OBJECTIVE: To determine whether cognitive learning potential measured with the dynamic Wisconsin Card Sorting Test has added value in predicting rehabilitation outcome in elderly patients post-stroke after controlling for age, ADL independence at admission, global cognitive functioning and depressive symptoms. METHODS: Participants were patients with stroke admitted to a geriatric rehabilitation unit. ADL independence (Barthel Index) at discharge was used as measure for rehabilitation outcome. Predictor variables included age, ADL independence at admission, global cognitive functioning (Montreal Cognitive Assessment), depressive symptoms (Geriatric Depression Scale) and cognitive learning potential measured with the dWCST. RESULTS: Thirty participants were included. Bivariate analyses showed that rehabilitation outcome was significantly correlated with ADL independence at admission (r = 0.443, p = 0.014) and global cognitive functioning (r = 0.491, p = 0.006). Regression analyses showed that the dWCST was not an independent predictor of rehabilitation outcome. ADL independence at admission was the only significant predictor of rehabilitation outcome (beta = 0.480, p = 0.007). CONCLUSIONS: Cognitive learning potential, measured with the dWCST has no added value in predicting rehabilitation outcome in elderly patients post-stroke. ADL independence at admission was the only significant predictor of rehabilitation outcome. REGISTRATION NUMBER NETHERLANDS TRIAL REGISTER: Trial NL7947.

A Biopsychosocial Approach to Persistent Post-COVID-19 Fatigue and Cognitive Complaints: Results of the Prospective Multicenter NeNeSCo Study.

OBJECTIVE: To evaluate whether psychological and social factors complement biomedical factors in understanding post-COVID-19 fatigue and cognitive complaints. Additionally, to incorporate objective (neuro-cognitive) and subjective (patient-reported) variables in identifying factors related to post-COVID-19 fatigue and cognitive complaints. DESIGN: Prospective, multicenter cohort study. SETTING: Six Dutch hospitals. PARTICIPANTS: 205 initially hospitalized (March-June 2020), confirmed patients with SARS-CoV-2, aged ≥18 years, physically able to visit the hospital, without prior cognitive deficit, magnetic resonance imaging (MRI) contraindication, or severe neurologic damage post-hospital discharge (N=205). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Nine months post-hospital discharge, a 3T MRI scan and cognitive testing were performed and patients completed questionnaires. Medical data were retrieved from medical dossiers. Hierarchical regression analyses were performed on fatigue severity (Fatigue Severity Scale; FSS) and cognitive complaints (Cognitive Consequences after Intensive Care Admission; CLC-IC; dichotomized into CLC-high/low). Variable blocks: (1) Demographic and premorbid factors (sex, age, education, comorbidities), (2) Illness severity (ICU/general ward, PROMIS physical functioning [PROMIS-PF]), (3) Neuro-cognitive factors (self-reported neurological symptoms, MRI abnormalities, cognitive performance), (4) Psychological and social factors (Hospital Anxiety and Depression Scale [HADS], Utrecht Coping List, Social Support List), and (5) Fatigue or cognitive complaints. RESULTS: The final models explained 60% (FSS) and 48% (CLC-IC) variance, with most blocks (except neuro-cognitive factors for FSS) significantly contributing. Psychological and social factors accounted for 5% (FSS) and 11% (CLC-IC) unique variance. Higher FSS scores were associated with younger age (P=.01), lower PROMIS-PF (P<.001), higher HADS-Depression (P=.03), and CLC-high (P=.04). Greater odds of CLC-high were observed in individuals perceiving more social support (OR=1.07, P<.05). CONCLUSIONS: Results show that psychological and social factors add to biomedical factors in explaining persistent post-COVID-19 fatigue and cognitive complaints. Objective neuro-cognitive factors were not associated with symptoms. Findings highlight the importance of multidomain treatment, including psychosocial care, which may not target biologically-rooted symptoms directly but may reduce associated distress.

The Effects of a Blended Care Intervention in Partners of Patients With Acquired Brain Injury - Results of the CARE4Carer Randomized Controlled Trial.

OBJECTIVE: To assess effects of the CARE4Carer blended care intervention on caregiver mastery and psychosocial functioning compared with usual care in partners of patients with acquired brain injury (ABI). DESIGN: Multicenter randomized controlled trial. SETTING: Nine sites for rehabilitation medicine. PARTICIPANTS: 120 partners of outpatients with ABI were randomly allocated to blended care (N=59) or usual care (N=61). INTERVENTION: The blended care intervention (20 weeks) was aimed at improving caregiving skills and consisted of 9 online sessions, combined with 2 face-to-face consultations with a social worker. MAIN OUTCOME MEASURES: Mastery was assessed with the Caregiver Mastery Scale, secondary outcome measures were caregiver strain (Caregiver Strain Index), family functioning (Family Assessment Device), anxiety and depression (Hospital Anxiety and Depression Scale), burden (self-rated), and quality of life (CarerQol). Assessments were performed at baseline, 24, and 40 weeks. RESULTS: The adjusted mean difference in caregiver mastery between intervention and control group at week 24 was 1.31 (SD3.48, 95% confidence interval (CI) -0.12 to 2.74, P=.072) and at week 40 was 1.31 (SD3.69, 95% CI -0.26 to 2.88, P=.100). In the per protocol analysis, the adjusted mean difference in caregiver mastery at week 24 was 1.53 (SD3.38, 95% CI 0.10 to 2.96, P=.036) and at week 40 was 1.57 (SD3.63, 95% CI 0.01 to 3.14, P=.049). Regarding secondary outcomes, caregiver strain was lower in the intervention group in the per protocol analysis at week 40. Family functioning was higher in the intervention group in week 24, whereas anxiety was lower at both timepoints. CONCLUSIONS: In the subset of participants who were able to complete the intervention, caregiver mastery and psychosocial functioning improved. Future work should focus on improving adherence as this will optimize beneficial effects of blended care.

Long-Term Follow-Up of Critically Ill Patients With Traumatic Brain Injury: From Intensive Care Parameters to Patient and Caregiver-Reported Outcome.

Abstract Traumatic brain injury (TBI) is associated with a high social and financial burden due to persisting (severe) disabilities. The consequences of TBI after intensive care unit (ICU) admission are generally measured with global disability screeners such as the Glasgow Outcome Scale-Extended (GOSE), which may lack precision. To improve outcome measurement after brain injury, a comprehensive clinical outcome assessment tool called the Minimal Dataset for Acquired Brain Injury (MDS-ABI) was recently developed. The MDS-ABI covers 12 life domains (demographics, injury characteristics, comorbidity, cognitive functioning, emotional functioning, energy, mobility, self-care, communication, participation, social support, and quality of life), as well as informal caregiver capacity and strain. In this cross-sectional study, we used the MDS-ABI among formerly ICU admitted patients with TBI to explore the relationship between dichotomized severity of TBI and long-term outcome. Our objectives were to: 1) summarize demographics, clinical characteristics, and long-term outcomes of patients and their informal caregivers, and 2) compare differences between long-term outcomes in patients with mild-moderate TBI and severe TBI based on Glasgow Coma Scale (GCS) scores at admission. Participants were former patients of a Dutch university hospital (total n = 52; mild-moderate TBI n = 23; severe TBI n = 29) and their informal caregivers (n = 45). Hospital records were evaluated, and the MDS-ABI was administered during a home visit. On average 3.2 years after their TBI, 62% of the patients were cognitively impaired, 62% reported elevated fatigue, and 69% experienced restrictions in ≥2 participation domains (most frequently work or education and going out). Informal caregivers generally felt competent to provide necessary care (81%), but 31% experienced a disproportionate caregiver burden. All but four patients lived at home independently, often together with their informal caregiver (81%). Although the mild-moderate TBI group and the severe TBI group had significantly different clinical trajectories, there were no persisting differences between the groups for patient or caregiver outcomes at follow-up. As a large proportion of the patients experienced long-lasting consequences beyond global disability or independent living, clinicians should implement a multi-domain outcome set such as the MDS-AB to follow up on their patients.
