Abstract

Background: Only few studies investigated the relation between concordance with treatment guidelines and treatment outcome in everyday treatment of bipolar disorder (BD). Prospective studies are scarce.

Methods: A nationwide, naturalistic, prospective study on the relation between guideline concordance and treatment outcome in the long-term outpatient treatment of patients with BD. Participants completed a survey on treatments received and various outcome measures at baseline and after one year.

Results: Of 839 patients who completed the baseline survey, 615 (73.3%) also completed the follow-up survey. Consistent with our a priori hypothesis, cross-sectional analyses at baseline showed correlations between guideline concordance with quality of life (r = .17, p < .001), treatment satisfaction (r = .17, p

Conclusions: Although guideline concordance was high throughout the study, change in guideline concordance was positively associated with change in quality of life, suggesting that especially in long-term treatment, continuous efforts to optimize ongoing treatment is essential.
