Objective:
To determine the efficacy of teaching
patients with bipolar disorder (manic-depressive psychosis) to identify early symptoms of relapse and seek prompt treatment from health services.
Design:
Single blind randomised controlled trial with matching on four baseline variables using a minimisation algorithm.
Setting:
Mental health services in four NHS trusts (one teaching, three non-teaching).
Subjects:
69 patients with bipolar disorder who had had a relapse in the previous 12 months.
Interventions:
Seven to 12 individual treatment
sessions from a research psychologist plus routine care or routine care alone.
Main outcome measures:
Time to first manic or
depressive relapse, number of manic or depressive relapses, and social
functioning examined by standardised interviews every six months for 18 months.
Results:
25th centile time to first manic relapse in experimental group was 65 weeks compared with 17 weeks in the control
group. Event curves of time to first manic relapse significantly differed between experimental and control groups (log rank 7.04, df=1,
P=0.008), with significant reductions in the number of manic relapses
over 18 months (median difference 30% (95% confidence interval 8% to
52%), P=0.013). The experimental treatment had no effect on time to
first relapse or number of relapses with depression, but it
significantly improved overall social functioning (mean difference 2.0 (0.7 to 3.2), P=0.003) and employment (mean difference 0.7 (0.1 to
1.3), P=0.030) by 18 months.
Conclusion:
Teaching patients to recognise early
symptoms of manic relapse and seek early treatment is associated with
important clinical improvements in time to first manic relapse, social
functioning, and employment.
