Abstract

Objectives: This systematic review aimed at providing a critical, comprehensive synthesis of international guidelines' recommendations on the long-term treatment of bipolar disorder type I (BD-I).

Methods: MEDLINE/PubMed and EMBASE databases were searched from inception to January 15th, 2019 following PRISMA and PICAR rules. International guidelines providing recommendations for the long-term treatment of BD-I were included. A methodological quality assessment was conducted with the Appraisal of Guidelines for Research and Evaluation-AGREE II.

Results: The final selection yielded five international guidelines, with overall good quality. The evaluation of applicability was the weakest aspect across the guidelines. Differences in their updating strategies and the rating of the evidence, particularly for meta-analyses, randomized clinical trials (RCTs) and observational studies, could be responsible of some level of heterogeneity among recommendations. Nonetheless, the guidelines recommended lithium as the 'gold standard' in the long-term treatment of BD-I. Quetiapine was another possible first-line option as well as aripiprazole (for the prevention of mania). Long-term treatment should contemplate monotherapy, at least initially. Clinicians should check regularly for efficacy and side effects and if necessary, switch to first-line alternatives (i.e. Valproate), combine first-line compounds with different mechanisms of action or switch to second-line options or combinations.

Conclusions: The possibility to monitor improvements in long-term outcomes, namely relapse prevention and inter-episode subthreshold depressive symptoms, based on the application of their recommendations is an unmet need of clinical guidelines. In terms of evidence of clinical guidelines, there is a need for more efficacious treatment strategies for the prevention of bipolar depression.

Keywords: bipolar disorder type I; clinical guidelines; long-term treatment; maintenance; practice algorithms.
