title: Modifying the Barthel Performance Index Score for use in patients with brain tumours.
abstract: Performance status scores are useful tools in the management of patients with malignant disease. No specific performance index score exist, however, for patients with glioma. The Barthel Index, has been used in our department because it has been widely used in patients following stroke and found useful. This study aims to establish whether a modification of the Barthel Index would be more appropriate for patients with glioma and, if so, what modifications should be made. The opinions of multidisciplinary health workers and carers experienced in helping patients with glioma were established by questionnaire. Difficulty with speech and the presence of seizures were statistically ranked the most significant disability in terms of overall performance status. As these are not included in the Barthel Index a modification is justified. However, to include new categories in a performance index but avoid increasing its complexity, existing categories have to be omitted. Therefore, the second aim of this study was to establish which categories within the Barthel contribute least to a change in the total score. Three-hundred-and-thirty-three prospectively recorded Barthel scores were evaluated in 81 patients over 2 years and the individual categories evaluated by multifactor analysis. The sensitivity of the categories 'bowel function' and 'independence in grooming' to a change in the total score was less than 1%. In conclusion, substituting 'speech difficulties' and the presence of seizure in place of 'bowel function' and 'independence in grooming' from the Barthel Index will improve the specificity for patients with glioma without reducing the sensitivity or acceptability for the patients and research nurses who most often complete them.(ABSTRACT TRUNCATED AT 250 WORDS)
