Scales for assessment of patients with traumatic brain injury

Pages 1631-1633 | Published online: 13 Nov 2015

Dear editor

We read with great interest the paper by Ślusarz et alCitation1 published in the Patient Preference and Adherence. The functional recovery after traumatic brain injury (TBI) is related to the severity of the brain lesion and the time after TBI. The consequences of brain damage remain beyond the acute phase, extending and modifying for a long period after the traumatic event.Citation2 Knowing the functional recovery after TBI is relevant to evaluating the results of new techniques and treatments to minimize the severity of the disability. As a result, the pathophysiology of disability after TBI and the mechanisms involved in functional recovery are the subject of investigations, which provide the foundation to direct rehabilitation programs and guide the development of individualized therapy after TBI.Citation3 Ślusarz et al’sCitation1 article focused on the role of establishing the relationships between measurements by the Glasgow Coma Scale (GCS) and the scales used for the assessment of functional capacity of TBI patients.

Although some studies have described the recovery of patients of TBI after trauma, there are few studies that evaluate the different aspects of functional capacity in the acute phase after brain injury and factors related to outcome. We agree with Ślusarz et alCitation1 that studying the functional capacity and assessing the activities of daily living in patients with TBI facilitate the planning of systematic assistance, implementation of neurological rehabilitation, reintegration of patients in society, and a better warranted quality of life. A strength of the study is to analyze the functional capacity assessed by different scales at admission and at discharge, highlighting the correlation of recovery in both periods with the level of awareness, and the comparison of different scales that assess functional capacity and activities of daily life.

Our group has great interest in the assessment of functional recovery of TBI patients analyzed by different scales, in particular, patients with severe diffuse axonal injury (DAI).Citation3,Citation4 As discussed by Ślusarz et al,Citation1 the evaluation of consciousness is a widely used prognostic parameter in the acute phase of trauma and identifies early the outcome of patients with severe TBI, and it is relevant in the face of the impairment of brain functions caused after TBI and the mechanisms involved in the recovery process. Clinical observations of TBI patients have suggested improvement during the first year, particularly during the first 6 months, with stabilizing of the recovery process thereafter.Citation2,Citation5Citation7 Research to assess the consequences for TBI patients showed that there is an improvement in functionality after trauma; however, how to measure functional recovery after TBI is still a challenge. Analysis of patients with severe TBI showed that advanced age and prolonged hospitalization were independent predictors of poor outcome after trauma.Citation6 The lowest score of the Glasgow Coma Scale on admission is a factor associated with dependence or death of TBI patients, assessed 3 months after the trauma.Citation7

Our researchCitation8 carried out with patients of DAI showed that severe DAI stood out as risk factor for mortality and dependence compared to focal injury. The length of hospitalization was identified as a risk factor related to dependence on outcome. In addition, other important scales can be used to assess functional recovery, mainly in severe trauma. We had used Katz scale and the Extended Glasgow Outcome Scale in patients with severe DAI, and we found similar results when assessing recovery at 6 months after DAI compared with results described by Ślusarz et al,Citation1 using correlation results of the functional capacity scale and the functional index “Repty”.

The results described by Sĺusarz et alCitation1 showed the importance of studying the recovery of patients with TBI after trauma since it identified greater independence of the patients after hospital discharge and a correlation between the level of awareness and functional capacity. The identification of functional recovery and its correlation with the outcome can guarantee the quality of care provided to patients and provide a better quality of life. However, we believe that functional recovery analysis of TBI patients is a complex issue, presents particularities, and maybe should be stratified according to severity of trauma, including the creation of appropriate scales for mild TBI, separated from moderate and severe TBI.

Dear editor

We would like to thank Rita de Cassia Almeida Vieira, Daniel Vieira de Oliveira, Manoel Jacobsen Teixeira, and Wellingson da Silva Paiva of Nursing School and Division of Neurological Surgery, University of Sao Paulo, Sao Paulo, Brazil, for showing interest in our publication and sharing their comment on usage of assessment scales in patients after traumatic brain injury.Citation1

We are glad that this team of experienced researchers has decided to join the discussion on this topic especially that they are experts in nursing management of neurosurgical patients.Citation2Citation4

The comment is very valuable due to its merit and significant results of clinical and nursing practice. The authors’ suggestion that the functional recovery analysis of patients with TBI should depend on the severity of injury (mild, moderate, and severe), which seems very interesting. We believe that this idea will be taken into consideration in the future on a bigger sample of patients. We will be happy to incorporate the experience of the Sao Paulo team into further studies.
