Evaluation of cognitive assessment in stroke rehabilitation

OBJECTIVE: To assess the effect of cognitive assessment on the functional outcome of stroke patients and quality of life for both patients and their carers. DESIGN: A multicentre, single-blind, randomized controlled trial. SETTING AND PARTICIPANTS: Two hundred and twenty-eight stroke patients were recruited from hospital wards in three UK centres. INTERVENTIONS: Patients were screened for cognitive impairment and randomly allocated to either routine care (116 patients) or routine care plus a detailed cognitive assessment (112 patients). MAIN OUTCOME MEASURES: Outcome was assessed three and six months after recruitment by an independent assessor blind to the intervention on Extended ADL, Cognitive Failures Questionnaire, General Health Questionnaire-28 for patients and carers and Carer Strain Index. RESULTS: There was no significant difference between the two groups in patients' functional outcome, perceived cognitive ability, level of psychological distress or satisfaction with care. There was a trend for the assessment group to have lower levels of carer strain (p = 0.06). CONCLUSIONS: The provision of information about cognitive assessment in stroke rehabilitation may decrease carer strain.
