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

The structure of the Early Rehabilitation Barthel Index (ERBI) should be modified: evidence from a Rasch analysis study

BACKGROUND

The Early Rehabilitation Barthel Index (ERBI) comprises seven items of the Early Rehabilitation Index and ten items of the Barthel Index. The ERBI is usually used to measure functional changes in patients with severe acquired brain injury (sABI), but its measurement properties have yet to be extensively assessed.

AIM

To study the unidimensionality and internal construct validity (ICV) of the ERBI through Confirmatory Factor Analysis (CFA), Mokken Analysis (MA), and Rasch Analysis (RA).

DESIGN

Multicenter prospective study.

SETTING

Inpatients from five intensive rehabilitation centers.

POPULATION

Two hundred and forty-seven subjects with sABI.

METHODS

ERBI was administered on admission and discharge to study its unidimensionality through CFA and MA and its ICV, reliability, and targeting through RA.

RESULTS

The preliminary analyses showed a lack of unidimensionality (RMSEA=0.460 >0.06; SRMR=0.176 >0.06; CFI=1.000 >0.950; TLI=1.000 >0.950). According to CFA, "Confusional state" and "Behavioral disturbance" items showed low factor loadings (<0.40), whereas these two items composed a separate scale within the MA. Furthermore, the baseline RA showed that three items misfitted ("Mechanical ventilation," "Confusional state," "Behavioral disturbances") and a lack of conformity of several ICV requirements. After deletion of three misfitting items and further non-structural modifications (i.e., testlets creation to absorb local dependence between items and item misfit), the solution obtained showed adequate ICV, adequate reliability for measurements at the individual level (PSI>0.85), although with a frank floor effect. This final solution was successfully replicated in a total sample of the subjects. After post-hoc modifications of the score structure of two out of three misfitting items, the subsequent CFA (RMSEA=0.044 <0.06; SRMR=0.056 <0.06; CFI=1.000 >0.950 TLI=1.000 >0.950) and MA showed the resolution of the unidimensional issues.

CONCLUSIONS

Although the ERBI is a potentially valuable tool for measuring functioning in the coma-to-community continuum, our analyses suggested its lack of ICV, partly due to an incorrect scoring design of some items. A new perspective multicenter study is proposed to validate a modified version of the ERBI that overcomes the problems highlighted in this analysis.

CLINICAL REHABILITATION IMPACT

Our results do not support the use of the original structure of the ERBI in clinical practice and research, as a lack of ICV was highlighted.

Early Rehabilitation Index: translation and cross-cultural adaptation to Brazilian Portuguese; and Early Rehabilitation Barthel Index: validation for use in the intensive care unit

Objetivo

Traduzir, adaptar transculturalmente para o português do Brasil o instrumento Early Rehabilitation Index e validar para uso na unidade de terapia intensiva o instrumento Early Rehabilitation Barthel Index, para avaliação do estado funcional.

Métodos

Foram executadas as seguintes etapas: preparação, tradução, reconciliação, tradução reversa, revisão, harmonização, pré-teste e avaliação psicométrica. Após esse processo inicial, a versão em português foi aplicada por dois avaliadores em pacientes que permaneciam pelo menos 48 horas internados na unidade de terapia intensiva. Verificou-se a confiabilidade da escala por meio da consistência interna, da confiabilidade entre avaliadores e do efeito piso e teto. Para a validade de constructo, correlacionou-se o Early Rehabilitation Barthel Index com instrumentos que usualmente são utilizados para avaliação do estado funcional na unidade de terapia intensiva.

Resultados

Participaram 122 pacientes com mediana de idade de 56 [46,8 - 66] anos. O Early Rehabilitation Barthel Index teve confiabilidade adequada com coeficiente alfa de Cronbach de 0,65. A confiabilidade entre avaliadores foi excelente, com coeficiente de correlação intraclasse de 0,94 (IC95% 0,92 - 0,96) e moderado a excelente com índice de concordância de kappa de 0,54 a 1,0. Os efeitos piso e teto foram mínimos. Observou-se a validade do Early Rehabilitation Barthel Index por meio das correlações com o escore total do Perme Escore (rô = 0,72), da Escala de Estado Funcional em UTI (rô = 0,77), do Physical Function in Intensive Care Test-score (rô = 0,69), do Medical Research Council sum score (rô = 0,58), além das dinamometrias de preensão palmar (rô = 0,58) e manual de coxa (rô = 0,55), todos com p < 0,001.

Conclusão

A versão adaptada do Early Rehabilitation Index para o português brasileiro e na sua totalidade, Early Rehabilitation Barthel Index é confiável e válida para avaliação do estado funcional dos pacientes na alta da unidade de terapia intensiva.

Validation of the munich swallowing score (mucss) in patients with neurogenic dysphagia: A preliminary study

BACKGROUND

The Munich Swallowing Score (MUCSS) is a clinician rated scale for the assessment of the functional level of swallowing saliva/secretions, food and liquids. The MUCSS consists of two eight-point subscales, MUCSS-Saliva and MUCSS-Nutrition. In a previous article, content validity and interrater reliability were described.

OBJECTIVE

The aim of the present study was to investigate criterion validity and sensitivity to change of the MUCSS.

METHODS

The research was conducted at a tertiary care academic hospital. Data were collected retrospectively in a cohort of 100 acute and subacute neurologic patients. Criterion validity was judged by comparison to the Gugging Swallowing Screen (GUSS), the Barthel Index (BI), Early Rehabilitation Barthel Index (ERI), Extended Barthel Index (EBI) and also by comparison to three physiological scales drawn from FEES videos: The Penetration - Aspiration Scale (PAS), the Yale Pharyngeal Residue Severity Rating Scale (YPR) and the Murray Secretion Scale (MSS). Changes in oral intake and saliva swallowing were followed up for three months.

RESULTS

Between MUCSS and scores directly reflecting dysphagic symptoms (GUSS, PAS, YPR, MSS, ERI), strong to moderate correlations were found, weaker but statistically significant associations were seen with global measures of disability (BI isolated, EBI-subscale cognitive functions). MUCSS was sensitive to positive change of saliva swallowing and oral intake during the recovery period.

CONCLUSIONS

These preliminary data suggest that the MUCCS is a valid scale and may be appropriate for documenting clinical change in swallowing abilities of patients with neurogenic dysphagia.

Discharge Destination from a Rehabilitation Unit After Acute Ischemic Stroke

Background: We reviewed numerous variables for ischemic stroke patients admitted to a rehabilitation unit to determine those that were statistically associated with discharge destination. Methods: A retrospective chart review of patients with ischemic stroke discharged from the rehabilitation unit between January 1, 2005 and December 31, 2015. Variables were examined for their association with discharge destination (home versus long-term care (LTC)). Univariable relationships with discharge destination were assessed, and a multivariable logistic regression model was built. Results: Univariate predictors of discharge to LTC: advanced age, decreasing admission and discharge functional independence measure (FIM) scores, increasing change in FIM score from admission to discharge, dependency, residence outside of home before the stroke, absence of a caregiver, urinary and bowel incontinence, low Berg balance score at admission and discharge, low Montreal Cognitive Assessment scores, smoking, chronic heart failure, and an inability to transfer. Multivariable logistic regression: five factors remained significant predictors with LTC disposition: advanced age, bowel incontinence, residence outside of the home prior to stroke, right hemisphere site of the stroke, and absence of a caregiver. Conclusions: Several easily measured variables were significantly associated with discharge to LTC versus home following stroke rehabilitation.

Factors influencing weaning from mechanical ventilation in neurological and neurosurgical early rehabilitation patients

BACKGROUND

Studies analyzing risk factors of weaning failure in neurological and neurosurgical early rehabilitation (NNER) patients are rare.

AIM

The aim of this study was to identify clinical factors influencing the weaning of NNER patients.

DESIGN

An observational, retrospective data analysis of a German multicenter study was performed.

SETTING

German neurological early rehabilitation centers.

POPULATION

Inpatient ventilated NNER patients (N.=192) were enrolled in the study.

METHODS

Demographical data, main diagnosis, medical devices, special medical care and assessment instruments of functional abilities, consciousness and independence in activities of daily living were accrued and compared between patients with and without successful weaning. The prognostic power of factors associated with weaning success/failure was analyzed using binary logistic regression.

RESULTS

In total, 75% of the patients were successfully weaned. Colonization with multi-drug resistant bacteria and the need for dialysis were independent predictors of weaning failure. Successfully weaned patients had a shorter length of stay, better functional outcome, and lower mortality than non-successfully weaned patients.

CONCLUSIONS

Successfully weaned patients differ from patients with weaning failure in several clinical variables. All these variables are associated with the morbidity of the patient, indicating that the weaning process is strongly influenced by disease burden.

CLINICAL REHABILITATION IMPACT

Functional abilities, level of consciousness, independence in activities of daily living, colonization with multi-drug resistant bacteria, need for dialysis and disease duration might help to predict the weaning process of NNER.

Early intensive rehabilitation after oral cancer treatment

PURPOSE

The treatment of oral cancer requires an effective rehabilitation strategy such as an early intensive rehabilitation (EIR) program.

MATERIALS AND METHODS

The medical records and data of 41 patients who participated in an EIR program and 20 control group patients were analyzed. These patients all underwent surgical resection of the primary tumor followed by microsurgical reconstruction using free flaps. The length of stay (LOS) at the acute care hospital was compared between the two groups. Four indexes were used to evaluate the effectiveness of the EIR program.

RESULTS

EIR patients stayed an average of 11.6 fewer days at the acute care hospital. All indexes showed significant improvements (p < 0.001). The Barthel Index (BI) and the Early Intensive Rehabilitation Barthel Index (EIR-BI) improved by 36.0 and 103.6 points, respectively. At discharge, the Bogenhausener Dysphagia Score (BODS) had improved to a score of 11.0 compared to the 13.9 at admission. EIR patients had a Work Ability Index (WAI) score of 25.7.

CONCLUSION

Length of stay at the acute care hospital can be reduced using early intensive rehabilitation if patients are transferred to an intensive rehabilitation clinic early.

Impact of Thyroid Hormone Levels on Functional Outcome in Neurological and Neurosurgical Early Rehabilitation Patients

Background

Neurological and neurosurgical early rehabilitation (NNER) is a specialized treatment option for patients with severe neurological disorders. The present study investigated whether thyroid hormone levels on admission have an impact on the outcome of NNER patients.

Method

The study included 500 NNER patients who were admitted to the BDH-Clinic Hessisch Oldendorf between 2009 and 2010. Data such as age, sex, diagnoses, comorbidities, Glasgow Coma Scale score, length of stay, and thyroid hormone levels (obtained as part of clinical routine care) were analyzed retrospectively. Improvement in the Early Rehabilitation Barthel Index (ERBI) at the end of the NNER treatment was defined as outcome parameter.

Results

Most patients made functional progress during treatment, as reflected in significant enhancements of the ERBI. Approximately half of the patients were transferred to further rehabilitation treatment. Young age, early onset of NNER treatment, low functional impairment on admission, and, in particular, low total T3 levels were independently associated with a good outcome.

Conclusion

Age, severity of disease, and time between injury and admission are known to predict outcome. The present study confirms the influence of these general factors. In addition, an association between thyroid hormones and functional outcome was demonstrated for NNER patients.
