[Guideline "Legal evaluation after closed brain injury in adulthood"]

In 2005 and 2013, the "Deutsche Gesellschaft für Neurowissenschaftliche Begutachtung" (German Society for Neuroscientific Evaluation) together with other societies developed and consented guidelines fort the legal evaluation of patients with closed head injuries and published them trough the National Working Group of Scientific Medical Societies and in this journal. Five years later, a revision was necessary, this was developed on the higher S2 k level of consent through a Delphi conference.

Criterion validity and sensitivity to change of the Early Rehabilitation Index (ERI): results from a German multi-center study

Background

Evaluation of functional status is difficult in neurological and neurosurgical early rehabilitation patients. The Early Rehabilitation Index (ERI) was introduced in Germany over 20 years ago, but since then validation studies are lacking. The ERI (range −325 to 0 points) includes highly relevant items including the necessity of intermittent mechanical ventilation or tracheostomy.

Methods

The present paper analyzed data from a German multi-center study, enrolling 754 neurological early rehabilitation patients. Together with ERI, Barthel Index (BI), Glasgow Coma Scale (GCS), Glasgow Outcome Score Extended, Coma Remission Scale (CRS), Functional Ambulation Categories and length of stay were obtained.

Results

ERI showed significant improvements from admission to discharge (p < 0.001). In addition, there were significant correlations of the ERI upon admission and at discharge with BI, CRS and GCS.

Conclusions

Evaluation of our study data suggest that the ERI may be used as a valid assessment instrument for neurological and neurosurgical early rehabilitation patients.

[The Value of Neuropsychological Legal Evaluations]

In the context of neurological assessment, neuropsychological deficits, in particular of attention and memory functions, usually require additional neuropsychological evaluation. Clinical neuropsychology also has at its disposal an inventory of validated and standardized tests for assessing symptom validity. Procedure, test selection, quality criteria and limitations of neuropsychological expert medical evaluations are presented. Independent expert evaluations should be conducted by a qualified clinical neuropsychologist.

[Catalogues of therapeutic nursing activities in neurological early rehabilitation]

Under the German DRG-system, hospital-based rehabilitation of still critically ill patients becomes increasingly important. The code for early neurological rehabilitation in the DRG-system's (Diagnosis Related Groups) list of operations and procedures requires an average daily therapeutic intensity of 300 min, part of which is being contributed by therapeutic nursing. As therapeutic aspects are integrated in other nursing activities, it is difficult to separate its time consumption. This problem is pragmatically resolved by catalogues of therapeutic nursing activities which assign plausible amounts of therapeutic minutes to each activity. The 4 catalogues that are used most often are described and compared. Nursing science has not focused yet on therapeutic nursing.

[The German guideline "legal evaluation after closed head injury"]

In 2005, the "Deutsche Gesellschaft für Neurowissenschaftliche Begutachtung" (German Society for Neuroscientific Legal Evaluation) together with other Societies published a guideline for the legal evaluation of patients with closed head injuries. Meanwhile, not only scientific progress in imaging techniques but also in other fields such as neuropsychology has necessitated a revision, which is presented here. In the mean time, the handling of guidelines has been systematised in Germany so that a registration with the Cooperation of German Medical Learned Societies is applied for and publication in the German Guideline Registry is expected.

Prognosis and prognostic factors in ADL-dependent stroke patients during their first in-patient rehabilitation – a prospective multicentre study

PURPOSE

This prospective longitudinal study aimed at a description of ADL-functioning and at an analysis, which clinical instruments predict independency 6 months after discharge from in-patient rehabilitation following disabling first stroke.

METHOD

A total of 147 patients with disabling first stroke were recruited from three neurological rehabilitation centres. They were assessed during their first in-patient rehabilitation with the NIH Stroke Scale, Hemispheric Stroke Scale (HSS), Activity Index, Barthel Index, Neurobehavioural Rating Scale, Cornell Depression Scale, and the prognostic prediction of the rehabilitation neurologist. The 6 months outcome was established with the Nottingham Extended ADL Scale (NEADL) and by the legal dependency status.

RESULTS

The best prediction of 6 months outcome as measured by the NEADL was obtained by the HSS and a multivariate model that also included the physician's prognostic prediction, both early in rehabilitation and at discharge. The dependency status was best predicted by the HSS and patient's sex.

CONCLUSION

Clinical scales performed during rehabilitation such as the HSS are valid for prediction of ADL-dependency 6 months after discharge.

Physicians' estimates of rehabilitation requirements after stroke and traumatic brain injury - a questionnaire survey in East Germany

PURPOSE

The provision of rehabilitation services is organized differently in Germany than most other countries, with large indication-specific in-patient centres. This study is aimed at the rehabilitative knowledge of physicians who initiate and conduct rehabilitation in Germany.

METHODS

Medical specialists routinely involved in the treatment and rehabilitation of patients with stroke and traumatic brain injury (TBI) from acute hospitals, rehabilitation centres, and the Medical Services of the Workers' Pension Funds of Sachsen-Anhalt and Mecklenburg-Vorpommern were included in a systematic questionnaire survey aiming at the rehabilitation requirements of patients under their care or evaluation. These specialists are crucial for decision-making in rehabilitation ressource allocation.

RESULTS

According to these experts, rehabilitation requirements for stroke and TBI patients are dominated by deficits in motor functions and daily-living. They are aware that TBI rehabilitation includes a greater focus on memory functions, problem-solving and attention, and in stroke on language functions. According to the surveyed specialists, the present system of medical rehabilitation in Germany covers the requirements of stroke and TBI patients only partially. Deficits are identified in out-patient and day clinic rehabilitation.

CONCLUSIONS

Although the knowledge of rehabilitation requirements is adequate in general, its large ranges reflect the necessity for further analysis. The opinions of the surveyed specialists reflect their respective professional setting. Advantages and disadvantages of the German system require further investigation.

[Use of the WHODAS II with stroke patients and their relatives: reliability and inter-rater-reliability]

The WHODAS II (World Health Organization Disability Assessment Schedule II) is a questionnaire derived from the ICF classification system (International Classification of Functioning, Disability and Health) for the evaluation of disabilities and handicaps. Data on its validity and reliability with respect to the consequences of stroke are largely lacking. The present study aimed at measurements of reliability of the WHODAS II in its application to stroke patients and their closest others. Eighty-four patient-relative pairs were assessed six months after stroke with the self- and observer-rating versions. From the patients' and relatives' judgements, Cronbach's alpha was computed as measurement of internal consistency, intra-class correlation coefficients as measurements of the inter-rater reliability of subscales and total scores, and Spearman's rho (rho) for the inter-rater reliability for single items. In addition, the inter-rater correspondence was calculated as the percentage of responses. The internal consistency was found to be good to excellent (alpha=0.81-0.99) both for patients' and relatives' judgements. Inter-rater reliabilities ranged from satisfactory for the subscale Understanding and Communication to excellent for the total score (ICC 0.64-0.94). However, the inter-rater reliability of the items as well as their percental correspondence was hardly satisfactory, with few exceptions in the realms of Life Activities and Self-Care (rho=0.24-0.90 and percental correspondence 29.6%-75.7%). Our results demonstrate that the WHODAS II is a reliable instrument for the assessment of stroke patients, both as a self- and an observer-rating questionnaire. Whereas the correspondence between patient and relative may be disparate with respect to single items - especially those not directly observable -, subscale and total scores seem to allow predictions based on observer judgements. The assessment of stroke patients' disabilities and handicaps through relatives' judgements with the WHODAS II scales is reliable.

[On the reliability of severely brain damaged persons as witnesses of their own injury]

We report a court verdict in the second retrial of a murder case that was based exclusively on the witness account of a severely brain damaged victim, and its reversal by the German Federal Court. The assessment of evidence had to weigh up the probability of the presence of real accounts of the crime versus the possibility of alternative explanations, i. e. trauma related confabulation. The defendant was acquitted.

Diagnostik bei chronisch fortschreitenden Demenzen

This review presents diagnostic criteria for the different dementia syndromes and mild cognitive impairment. It is being claimed that in view of the current pharmacological interventions and after exclusion of symptomatic dementia, a controlled trial with cholinesterase inhibitors or memantine is more efficient than elaborate diagnostics. Efficiency of differential diagnosis will increase when drugs are available that specifically improve the different degenerative dementias and vascular dementia. Clinical pictures of the various dementia syndromes are briefly described.

Release of glial fibrillary acidic protein is related to the neurovascular status in acute ischemic stroke

This study aimed at an analysis of glial fibrillary acidic protein (GFAP) in acute ischemic stroke, its association with the neurovascular status and its potential value as monitoring parameter. In 53 consecutive patients, serial venous blood samples were taken on admission, 6, 12, 18, 24, 48, 72, 96, and 120 h after stroke onset. The neurovascular status was assessed by repetitive extracranial and transcranial duplex sonography. Neurologic deficits were quantified by the National Institutes of Health stroke scale, and functional outcome was assessed with the modified Rankin Scale. Mean GFAP values were elevated from admission on with highest levels 48 h after stroke onset. GFAP release was highly correlated with severity of neurologic deficits and infarct volume. In patients with persistent middle cerebral artery occlusion, GFAP increased significantly compared with patients with normal sonographic findings (P = 0.019) and recanalization after thrombolysis resulted in a significant reduced increase (P = 0.038). GFAP concentrations were associated with the functional outcome after 3 months. Release kinetics of GFAP are associated with patients clinical deficits and infarct volume, depend on the neurovascular status on admission and on early recanalization after thrombolysis, and may be used as an additional predictor of the early course and functional outcome.

A Longitudinal Study of Health-Related Quality of Life of First Stroke Survivors’ Close Relatives

BACKGROUND AND PURPOSE

Mental and social burdens of stroke patients' relatives have been investigated repeatedly, but there is little information about their quality of life (QoL). The purpose of the study was to describe the health-related QoL of stroke patients' relatives at 3 points in time after the stroke.

METHOD

Sixty-four closest relatives of patients suffering from a disabling stroke were questioned at admission to inpatient rehabilitation as well as 6 months and 1 year after discharge with the SF36 (short form 36-item questionnaire) and about probable covariates.

RESULTS

During inpatient rehabilitation relatives' perception of their physical role as well as of all mental health scales was significantly lower than the normative data. We found improvements in all scales except physical functioning between inpatient rehabilitation and 6 months after discharge. Deteriorations between 6 months and 1 year occurred in physical functioning, role physical, social functioning, role emotional and mental health.

CONCLUSIONS

Changes in perceived health-related QoL indicate that relatives go through different stages while coping with the chronic illness of their family member during rehabilitation and in the first year after discharge. These findings may aid support and counseling.
