The availability of service-use data at each follow-up point is detailed in Table 9. Full data
were available for almost all randomised cases at BSL (95%). At the 12-month interview, full
service-use data were available for around 80% of the sample and at the 24-month interview for
around 75% of the sample. Full service-use data for the entire 2-year follow-up were available for
69% of the sample and it is these 286 cases that are included in the base-case analysis. The BSL
characteristics of the 286 participants included in the primary analysis and the 131 excluded were
very similar and are detailed in Table 10.
The mean number of contacts with each service is detailed by randomised group in Table 11.
Participants in all groups used staffed accommodation; the mean number of weeks over the
24-month follow-up period was between 33 and 36. Use of hospital services, particularly
inpatient care, is high in all groups, although those randomised to the activity group had a higher
mean number of nights in hospital than those in the art and standard treatment groups. This
difference was a result of more participants in the activity group spending the entire follow-up
as inpatients. Use of community services was comparable across the randomised groups, with
community mental health services such as community psychiatric nurses (CPNs), hometreatment
teams and day and drop-in centres being the most frequently used.
The total cost of services used is detailed in Table 12. At BSL, average costs per participant are
highest in those randomised to activity groups; the higher costs are owing to higher rates of
inpatient stays in this group and lowest in those randomised to art therapy.
