3 Early intervention in bipolar disorder? A number of randomised trials have investigated the effect of combined pharmacological and psychological interventions and various healthservice interventions in bipolar disorder.but none of the studies have specifically investigated the effect in the early stages of bipolar disorder. 3

4 7 indications from observational studies that early intervention may improve course and outcome 1. Progressive course of illness with increasing risk of recurrence for every new episode (Kessing et al, 1998, 2004) 4

6 7 indications from observational studies that early intervention may improve course and outcome 1. Progressive course of illness with increasing risk of recurrence for every new episode (Kessing et al, 1998, 2004) 2. Delay to first treatment is associated with more time depressed, greater severity of depression, greater number of episodes and more days of ultradian cycling (Post et al, 2010) 6

Progressive course of illness with increasing risk of recurrence for every new episode (Kessing et al, 1998, 2004) 2. Delay to first treatment associated with more time depressed, greater severity of depression, greater number of episodes, more days of ultradian cycling (Post et al, 2010) 3. Response to lithium monotherapy decreases with the occurrence of multiple prior episodes (Kessing et al, 2011) 7

Progressive course of illness with increasing risk of recurrence for every new episode (Kessing et al, 1998, 2004) 2. Delay to first treatment associated with more time depressed, greater severity of depression, greater number of episodes, more days of ultradian cycling (Post et al, 2010) 3. Response to lithium monotherapy decreases with the occurrence of multiple prior episodes (Kessing et al, 2011) 4. The rate of response to lithium is increased when started at first psychatric contact rather than at later contacts (Kessing et al, 2014) 8

10 7 indications from observational studies that early intervention may improve course and outcome (con t) 5. Mood stabilizers prescribed for bipolar disorder may have neuroprotective abilities (Manji et al, 2000; Fountoulakis et al, 2008) 10

11 7 indications from observational studies that early intervention may improve course and outcome (con t) 5. Mood stabilizers prescribed for bipolar disorder may have neuroprotective abilities (Manji et al, 2000; Fountoulakis et al, 2008) 6. The prevalence of cognitive dysfunction may increase with affective episodes and the risk of dementia seems increased for patients with bipolar disorder (Silva et al, 2013) 11

13 7 indications from observational studies that early intervention may improve course and outcome (con t) 5. Mood stabilizers prescribed for bipolar disorder may have neuroprotective abilities (Manji et al, 2000; Fountoulakis et al, 2008) 6. The prevalence of cognitive dysfunction may increase with affective episodes and the risk of dementia seems increased for patients with bipolar disorder (Silva et al, 2013) 7. Patients may profit from psychoeducation before potential cognitive disturbances may occur during the long-term course of illness (Berk et al, 2007). 13

14 Specialized mood disorder clinics? It has been claimed that specialized bipolar units and programs such as, e.g., the Bipolar Disorders Programme at the Barcelona Hospital Clinic are needed to improve outcome and advance research in bipolar disorder (Vieta, 2012)..but there is no randomised trial on the effects of such specialized units. 14

15 Treatment in a specialised outpatient mood disorder clinic versus standard treatment in the early course of bipolar disorder: a randomised multicenter clinical trial within The Mental Health Services in the Capital Region of Danmark Lars Vedel Kessing, Hanne Vibe Hansen, Ellen Margrethe Christensen, Henrik Dam, Christian Gluud, Jørn Wetterslev, and The Early Intervention Affective Disorders (EIA) Trial Group* * Members of the EIA Trial Group also encompass Klaus Damgård Jakobsen, Ejnar Bundgaard Larsen, Martin Balslev Jørgensen, Maj Vinberg, Rikke Engel, Flemming Mørkeberg Nilsson, Nana Hengstenberg, Birgitte Bjerg Bendsen, Hans Mørch Jensen, Rie Lambæk Mikkelsen, Birgit Straasø, Jens Abraham. 15

16 Early intervention in bipolar disorder Aim: In a RCT to investigate whether treatment in a specialized bipolar unit program, combining optimised pharmacological treatment with group psychoeducation, early in the course of illness among patients discharged from their first hospitalisations for bipolar disorder improve long-term outcome compared with standard psychiatric outpatient treatment. 16

17 Early intervention in bipolar disorder Specialized bipolar unit 2-year program: Optimised pharmacological treatment: evidence focused treatment in accordance with the guidelines from the British Association for Psychopharmacology, 2009 with focus on mood stabilising agents (lithium, valproate, lamictal and atypical antipsychotics) 3 sequential groups A) settling-in group: focus on the current clinical status and beliefs and experiences in relation to the recent hospitalisation. B) following remission: psychoeducation once a week for 15 weeks (shortened version ad modus F Colom) C) discharge group: learn to live and identify early warning signals 17

18 Early intervention in bipolar disorder Inclusion: Patients discharged from their first, second, or third hospitalisation from an inpatient psychiatric ward with an ICD- 10 diagnosis of single manic episode or bipolar disorder as the primary diagnosis. Comorbidity with alcohol or substance abuse and other psychiatric disorders were allowed. Age between 18 and 70 year old. Exclusion: moderate or severe dementia poor understanding of Danish any kind of commitment 18

19 Early intervention in bipolar disorder Primary outcome Re-admission to psychiatric ward after discharge from the index hospitalisation. Data on re-hospitalisation were obtained from the Danish Psychiatric Central Register Secondary outcomes Use of mood stabilizers (lithium or anticonvulsants), atypical antipsychotics and/or antidepressants. Tertiary outcome Satisfaction with care (Verona Service Satisfaction Scale- Affective Disorder (VSSS-A)) 19

28 Two-year treatment mean costs per patient in the Mood disorder clinic versus standard care (euro). Total direct net costs when including saved hospitals beds: Treatment in the mood disorder clinic was 3,194 euro less per patient than for standard care, corresponding to 11 % of the costs for standard care. 28

29 29 patients between 18 and 25 years of age Patients between 18 and 25 years (HR 0.33, 95% CI 0.10 to1.07; p=0.064) Patients 26 years or older (HR 0.68, 95% CI 0.40 to1.14, p=0.14). 1 Kessing et al, K Journal Affective Disorders, 2014 Jan; :

30 29 patients between 18 and 25 years of age Patients between 18 and 25 years (HR 0.33, 95% CI 0.10 to1.07; p=0.064) Patients 26 years or older (HR 0.68, 95% CI 0.40 to1.14, p=0.14). 2 Younger adults treated in the mood disorder clinic used mood stabilizers and antipsychotics more than those treated in standard care.

31 Early intervention in young patients with bipolar disorder Young adults with bipolar disorder may benefit even more than older adults from early intervention combining pharmacological treatment and group psychoeducation. Kessing et al, J Affect Disorders, 2014 Jan; :

32 Limitations Early intervention? - Half of the patients had had their first hospitalisation ever. - High median age of 35.6 years at inclusion in the study (although 25% were below 28 years and 25% above 47 years). Generalisation? - To bipolar I patients with the more severe disorders leading to hospitalisation 32

33 The first randomised trial on Early intervention in bipolar disorder Conclusion Treatment in a specialised mood disorder clinic early in the course of bipolar disorder substantially reduces psychiatric re-hospitalisations and increases satisfaction with care. And more so among young patients. and save total net costs. 33
