Question In patients with bipolar disorder receiving routine care, is an education programme that trains patients to identify early symptoms of relapse effective in reducing manic and depressive relapses and improving social functioning?
Randomised, single blind, controlled trial with 18 months of follow up.
3 NHS trusts in north west England.
69 patients who had a lifetime diagnosis of bipolar disorder, had had ≥2 relapses with 1 in the previous 12 months, and were between 18 and 75 years of age (mean age 45 y, 69% women). Exclusion criteria were inability to communicate in English, drug or alcohol abuse as a primary problem, or organic cerebral cause for bipolar disorder. Follow up was 99% for relapse and 86% for social functioning.
Patients were allocated to training plus routine care (n=34) or routine care alone (n=35). Patients in the training group collaborated with a research psychologist to learn to identify prodromal symptoms of manic or depressive relapse and to produce and rehearse an action plan once prodromes were recognised. Routine care consisted of drug treatment; monitoring of mood and adherence to treatment; support; education about bipolar disorder; and, if necessary, inpatient care.
Main outcome measures
Relapse (≥5 d of symptoms of mania, hypomania, mixed affective disorder, or depression), time to relapse, and overall social functioning by summing the scores on 8 areas measured using a 4 point scale.
Patients who received training plus routine care had a longer time to first manic relapse than those patients who received routine care alone (25th centile time to first relapse 65 v 17 wks, p=0.008) but the groups did not differ for time to first depressive relapse (25th centile time to first depressive relapse 21 v 26 wks, p=0.19). At 18 months, fewer patients in the training group had manic relapses than the control group patients (p=0.013); the groups did not differ for depressive relapses (p=0.15) (table⇓). Greater improvement in social functioning from baseline occurred in the training group than in the control group: the mean difference in change in social function score was 1.97 (95% CI 0.7 to 3.23) and in employment score was 0.70 (CI 0.07 to 1.33).
Training patients with bipolar disorder to recognise early symptoms of relapse reduced manic but not depressive relapses and improved social functioning.
This study by Perry et al shows that the addition of a training programme to teach patients to identify early symptoms of manic or depressive relapse in combination with an action plan once early symptoms had been recognised, increases time to a manic relapse. In contrast, it decreases time to a depressive relapse, although not significantly. As a result of this study, training can be considered an important element of a psycho-educational programme that should be offered to patients with bipolar disorder. A psycho-educational programme consists of several sessions in which patients (and sometimes their relatives) learn about the symptoms, causes, and treatment of the disorder; and may include written materials and video tapes. It has been shown that such programmes can result in better knowledge about the treatment and a decrease in level of expressed emotion.1, 2 It should be noted, however, that without participating in a psycho-educational programme, many patients can learn about their disorder (and the early symptoms of relapses) from individual contact with their treating physician or from health consumer resources.3 It is possible therefore that the effect of a training and psycho-education programme depends on what patients already know of their disorder. As regards applicability, not all patients who might be eligible for a training and psycho-educational programme actually want to follow it (in this study, 69 of 179 eligible patients participated in the study).
