Abstract

BACKGROUND:

The Bipolar Comprehensive Outcomes Study (BCOS) is a 2-year, observational study of participants with bipolar I or schizoaffective disorder examining clinical, functional, and economic outcomes associated with naturalistic treatment.

METHODS:

Participants prescribed mood stabilisers were assessed using various measures, including the Young Mania Rating Scale (YMRS), 21-item Hamilton Depression Rating scale (HAMD21), Clinical Global Impressions-Bipolar Version Severity of Illness scale (CGI-BP), and the EuroQol instrument (EQ-5D).

RESULTS:

240 participants were recruited from two sites. On average, participants were 41.8+/-12.7 years of age (mean+/-SD), 58.3% were female, and 73.3% had a diagnosis of bipolar I disorder at study entry. The majority of participants were moderately ill, with an average CGI-BP Overall score of 3.8+/-1.3. Most participants had subthreshold mania and depression symptoms, indicated by HAMD21 Total 13.4+/-8.6, CGI-BP Depression 3.2+/-1.3, YMRS Total 8.2+/-8.5 and CGI-BP Mania 3.0+/-1.6 average scores. For bipolar participants, 94.6% of hospitalisations for psychiatric treatment in the past 3 months were single admissions (vs. 65.2% for schizoaffective participants, p=.002). Bipolar participants rated their overall health state higher (EQ-5D scores: 68.2+/-18.8 vs. 61.6+/-22.7, p=.023), had a higher mean weekly wage ($500-$999, 21.3% vs. 6.3%), lower unemployment (22.2% vs. 48.4%), and higher romantic relationship status (47.1% vs. 26.6%).

LIMITATIONS:

The observational design and small sample size may have limited the causal relationships and generalisability within the current findings.

CONCLUSIONS:

Participants were characterised by social and occupational dysfunction at entry, but schizoaffective participants appeared to be more severely affected. Effective treatment is required to address both clinical and functional impairment.
