RESUMO
OBJECTIVE: This study explored factors which predict stroke survivors who could achieve "clinically significant functional gain" and return home when being discharged from a local hospital after in-patient stroke rehabilitation programme. METHODS: This study included 562 inpatients with stroke who were residing at community dwellings before onset of stroke, and transferred to a convalescent hospital for rehabilitation from four acute hospitals over one year. The main outcome variables of prediction were (a) achieving "clinically significant functional gain" as measured by (a1) achievement of "minimal clinically important difference" (MCID) of improvement in Functional Independence Measure Motor Measure (FIM-MM)", (a2) one or more level(s) of improvement in function group according to the patients' FIM-MM, and (b) discharge to home. Sixteen predictor variables were identified and studied firstly with univariate binary logistic regression and those significant variables were then put into multivariate binary logistic regression. RESULTS: Based on multivariate regression, the significant predictors for "clinically significant functional gain" were: younger age <75 years old, higher Glasgow Coma Scale score at admission, with haemorrhagic stroke, intermediate FIM-MM function group. Those significant predictors for "discharge to home" were: living with family/caregivers before stroke, higher FIM score at admission, and one or more level(s) of improvement in FIM-MM function group. CONCLUSIONS: This study identified findings consistent with overseas studies in additional to some new interesting findings. Early prediction of stroke discharge outcomes helps rehabilitation professionals and occupational therapists to focus on the use of appropriate intervention strategies and pre-discharge preparation.
RESUMO
BACKGROUND: Stroke, a common cerebrovascular accident, usually results in various extents of functional disability. Extensive studies have shown that ocular and visual problems are common in patients with stroke. Unfortunately, current stroke rehabilitation programs rarely address stroke-related ocular and visual problems in Hong Kong. METHODS: To examine how visual impairment (for example, deterioration in visual acuity and restriction in visual field) affects the stroke population in Hong Kong, vision screening was conducted for post-stroke patients attending in-patient and out-patient stroke clinics at two hospitals. RESULTS: One hundred and thirteen stroke patients were recruited. The percentage of various aspects of visual problems in Hong Kong post-stroke patients was generally lower than that reported in Western countries; however, a high percentage of patients had deficits in oculomotor (53.1 per cent) and vergence functions (11.5 per cent), restrictions in binocular visual field (11.5 per cent) and impairment in visual acuity (worse than 0.30 logMAR, 29.8 per cent). Conversely, only a small proportion of patients noticed problems with their vision (for example, diplopia and blurry vision) through subjective reports. This revealed that many post-stroke patients had undetected or undiagnosed ocular and visual problems. Appropriate referral was given to patients with visual problems for further evaluation and treatment. CONCLUSION: Neglecting visual problems may impose deteriorating effect on patients' stroke rehabilitation and functional independence and lead to increased incidents of injury. To address this potential hindrance in rehabilitation, formal screening for visual problems in stroke patients in a rehabilitation setting is essential.
