ORIENTATION IN THE ACUTE AND CHRONIC STROKE PATIENT - IMPACT ON ADL AND SOCIAL ACTIVITIES - THE COPENHAGEN STROKE STUDY

Objectives: To determine the influence of initially lowered orientatio n on rehabilitation outcome in stroke patients, and how decreased orie ntation 6 months after stroke influences ADL and social activities. De sign: Prospective, consecutive, and community based. Setting: A stroke unit receiving all acute stroke patients from a well-defined catchmen t area. All stages of rehabilitation were completed within the unit. P atients: 524 patients with acute stroke. Main Outcome Measures: Basic ADL assessed by the Barthel Index (BI) at discharge; discharge placeme nt; higher level ADL and social functions assessed by the Frenchay Act ivity Index (FAI) at a B-month follow-up. Results: The independent inf luence of orientation in acute stroke on rehabilitation outcome was an alyzed with multiple linear and logistic regression models, using init ial stroke severity (Scandinavian Neurologic Stroke Scale), initial BI , age, sex, comorbidity, prior stroke, and marital status as covariate s. A one-point decrease in orientation decreased BI with 9 points (coe fficient b = 8.66, SE(b) = 1.02, p < .0001) and reduced the likelihood (1.49, 95% CI: 1.05 to 2.11) of discharge to independent living (b = .40, SE(b)= .18, p = .026). Followup examinations 6 month poststroke s howed that decreased orientation at this point still exerted a marked, negative influence on ADL and social functions (BI: coefficient b = 1 2.06, SE(b) = 1.95, p < .0001; FAI: coefficient b = 6.28, SE(b) = 1.42 , p < .0001). Conclusion: The level of orientation influences basic AD L and higher level ADL and social activities in acute as well as chron ic stroke. This finding suggests that rehabilitation of memory and att ention might be relevant in stroke patients with impaired orientation.
