A randomised controlled comparison of alternative strategies in stroke care

Objectives: To compare outcomes between stroke patients managed on the stroke unit, on general wards with stroke team support or at home by specialist domiciliary team and to derive prognostic variables that will identify patients most suitable for management by each strategy. To describe organisational aspects of individual strategies of stroke care and to evaluate cost-effectiveness of each strategy and its acceptability to patients, carers and professionals. Design: Prospective single-blind randomised controlled trial undertaken in patients recruited from a community-based stroke register. Setting: Suburban district in south-east England. Participants: Patients with disabling stroke who could be supported at home. Interventions: The stroke unit gave 24-hour care provided by specialist multidisciplinary team based on clear guidelines for acute care, prevention of complications, rehabilitation and secondary prevention. The stroke team provided management on general wards with specialist team support. The team undertook stroke assessments and advised ward-based nursing and therapy staff on acute care, secondary prevention and rehabilitation aspects. Domiciliary care involved management at home under the supervision of a GP and stroke specialist with support from specialist team and community services. Support was provided for a maximum of 3 months. Main outcome measures: The primary measure was death or institutionalisation at 1 year. Secondary measures were dependence, functional abilities, mood, quality of life, resource use, length of hospital stay, and patient, carer and professional satisfaction. Results: Of the 457 patients randomised, 152 patients were allocated to the stroke unit; 152 patients to stroke team and 153 patients to domiciliary stroke care (average age 76 years, 48% women). The groups were well matched for baseline characteristics, stroke type and severity, level of impairment and initial disability. Fifty-one (34%) patients in the domiciliary group were admitted to hospital after randomisation. Mortality and institutionalisation at 1 year were lower on stroke unit compared with stroke team or domiciliary care. Significantly fewer patients on the stroke unit died compared with those managed by the stroke team. The proportion of patients alive without severe disability at 1 year was also significantly higher on the stroke unit compared with stroke team or domiciliary care. These differences were present at 3 and 6 months after stroke. Stroke survivors managed on the stroke unit showed greater improvement on basic activities of daily living compared with other strategies. Achievement of higher levels of function was not influenced by strategy of care. Quality of life at 3 months was significantly better in stroke unit and domiciliary care patients. There was greater dissatisfaction with care on general wards compared with stroke unit or domiciliary care. Poor outcome with domiciliary care and on general wards was associated with Barthel Index
