Table 5 shows the level of cost variation and suggests that there is a clear inverse relationship between Barthel ADL score and costs, with the most dependent patients (Barthel 0-8) being the most expensive.
Weights were derived for each patient to reflect relative physical dependency, which was measured by the average of 7-day and discharge Barthel ADL scores. For example, a patient with a score twice that of the mean for all patients would have a weight of 0.5.
In addition, three-band sub-group analysis (grouped by Barthel ADL scores measured at 7 days post-stroke) on costs was carried but.
To gain further insight into whether the level of physical dependency influenced costs, patients were divided into three sub-groups based on 7-day Barthel ADL scores. These cut-off scores were chosen following Granger et al.
These analyses showed that there was little to choose in terms of efficacy between hospital-based and home-based [TABULAR DATA FOR TABLE I OMITTED] [TABULAR DATA FOR TABLE II OMITTED] therapy provided at similar levels of intensity, but a slight advantage of home therapy was noted in terms of improving the Barthel ADL score between discharge and 6 months.
An analysis comparing the outcomes of hospital-based and home-based rehabilitation was made for all patients in the two trials (thus comparing home therapy against hospital-based therapy) and a similar analysis was undertaken excluding the DOMINO patients under 60 or who had Barthel ADL scores of 20/20 at trial entry (thus matching for protocol differences).
Extended ADL scores at 6 months after discharge from hospital were independently predicted by the Barthel ADL score at discharge from hospital, the age of the patient, previous mobility, time spent in hospital for the stroke, the abbreviated mental test score at discharge and whether the patient was living alone or not.
After the Extended ADL was returned, or 2 weeks after sending for those who had not returned their forms by this time, patients were interviewed to find out what sort of accommodation they were living in, their Barthel ADL score [5, 6] and whether they received social services or were visited by a district nurse.
Relationship between Extended ADL and Barthel ADL scores: Barthel scores were obtained on all 303 patients.
