Standardized nutritional supply versus individual nutritional assessment: Impact on weight changes, complications and functional outcome from neurological early rehabilitation.

BACKGROUND & AIMS: Approximately 55% of neurological and neurosurgical early rehabilitation (NNER) patients are in need of enteral nutrition, but long-term nutritional assessment of these critically ill patients is suboptimal. Therefore, this study analyzed the effect of an individual nutritional assessment on weight changes during rehabilitation and impact on complications and functional outcome. METHODS: 170 NNER patients on enteral nutrition were enrolled in the study. According to the initial ward, patients were assigned to receive standardized enteral nutrition (n = 107, control group) or an individual nutritional assessment (n = 63, intervention group). Weight changes, complications, assessment of the functional outcome (Early Rehabilitation Index, Barthel Index, Early Rehabilitation Barthel Index) and the length of stay were recorded and compared between groups using non-parametric tests for non-paired samples (Mann-Whitney U test for metric data or the χ2 test for categorical data) or paired samples (Wilcoxon test). In addition, daily energy requirement was calculated and compared with daily intake. Correlation analysis by Spearman was performed to investigate linear relationship between weight changes and the difference of administered and calculated calories in both study groups. RESULTS: A weight loss was observed in the control group, whereas the weight of the intervention group remained stable over time. The difference between calculated and administered calories correlated with weight changes in the control group. Regarding complications during rehabilitation, control patients showed more frequently impaired diuresis. In addition, control patients were suffering longer from diarrhea than patients of the intervention group. Both groups improved in functional status to a comparable degree. Relationships between these improvements and weight changes or administered calories could not be found. CONCLUSIONS: Individual nutritional assessment had not an additional affect for the improvement of functional outcome or the prevention of complications. However, weight turned out to be more stable and signs of nutritional incompatibilities are less frequent among patients being treated with an individualized nutritional assessment.

Nutritional situation of enterally fed patients in neurological early rehabilitation and impact of nutritional status on functional outcome.

BACKGROUND & AIMS: Studies focusing on the nutritional status of neurological and neurosurgical early rehabilitation (NNER) patients are limited. The aim of the current study was to determine the nutritional status of NNER patients upon admission, to observe weight changes and to investigate the influence of nutritional status on complications and outcome. METHODS: 109 enterally fed NNER patients were included in this prospective observational study. Weight changes, complications, neurological outcome scores (Early Rehabilitation Index [ERI], Barthel-Index [BI]) and the length of stay (LOS) were recorded. In addition, daily energy requirement was calculated and compared with daily intake to identify under-/optimally- and oversupplied patients. RESULTS: A general weight loss was observed in the study group. Weight changes during rehabilitation differed between men and women as well as between under- and oversupplied patients. Nutritional supply during rehabilitation had no influence on the LOS and the change of neurological outcome scores, but significant differences in the frequency of nosocomial infections was observed between under-/optimally- and oversupplied patients. The nutritional status (weight group on admission) had a crucial impact on neurological outcome scores, indicated by lower BI at discharge in normal-compared to underweight patients. In addition, underweight + undersupplied patients showed a significantly lower improvement of the BI than underweight + oversupplied patients. To the contrary, underweight + oversupplied patients had a higher BI improvement than underweight + optimally supplied patients. CONCLUSIONS: The nutritional status upon admission in combination with the nutritional supply during rehabilitation appears to have an impact on changes of neurological outcome scores.

[5-Year-Follow-up of the MEmbeR Multicenter Study on Medical-Occupational Rehabilitation]. / 5-Jahres-Follow-Up der multizentrischen Evaluationsstudie zur medizinisch-beruflichen Rehabilitation (MEmbeR).

In Germany, medical-occupational rehabilitation represents an essential link between rehabilitation programs focusing either on medical or occupational rehabilitation. Its main objective is return to work. The current study presents the vocational integration 5 years after medical-occupational rehabilitation and determines possible prognostic factors for long-term occupational integration. To evaluate the effectiveness of medical-occupational rehabilitation, a 5-year-follow-up interview was conducted with participants (n=105) of the multicenter study on medical-occupational rehabilitation (MEmbeR). As a main result, 76% of the participants were still employed 5 years after medical-occupational rehabilitation and the return to work rate was 57%. Prognostic factors for long-term occupational integration could not be identified. However, a low degree of disability, an unrestricted capacity for teamwork as well as an unrestricted ability to judge might be beneficial factors for a successful reintegration. The high amount of participants who returned to work 5 years after medical-occupational rehabilitation, supports the concept of medical-occupational rehabilitation. However, more studies are needed to identify further factors influencing the outcome.

[Assessment of Occupational Problems in Neurological Rehabilitation]. / Assessment beruflicher Problemlagen in der Neurorehabilitation.

Introduction: The so-called Würzburg Screening (WS) is recommended for assessing occupational problems among rehabilitation patients. However, it is unclear whether it can be used in neurological rehabilitation. Data of the WS as well as of a medical opinion of occupational problems (both assessed at the beginning of rehabilitation) was compared with prognoses of occupation at the end of rehabilitation. Methods: Data of 347 neurological post-acute rehabilitation patients were analyzed. Data of the WS as well as of a medical opinion of occupational problems (both assessed at the beginning of rehabilitation) was compared with prognoses of occupation at the end of rehabilitation. Results: The sensitivity of the WS to predict poor occupational outcome was 61.5 % while its specificity was 59.4 %. When combined with medical opinion, its sensitivity was higher (75 %) with a specificity of only 50.9 %. Regarding the prediction of further need for rehabilitation, the WS had a sensitivity of 56.3 % and specificity 76.4 %. Combined with the medical assessment, the sensitivity increased to 76.5 %, whereas the specificity was slightly lower with 76,1 %. Conclusion: Neither the WS alone nor the combination with a medical assessment allows valid prognoses of occupational problems and further rehabilitation needs at the beginning of rehabilitation. This suggests that the validity of the WS, which has been demonstrated for other indications, does not simply apply to neurological rehabilitation. Further studies are necessary to determine the validity of this scale.
