Bipolar disorder detection, ascertainment, and treatment: primary care physician knowledge, attitudes, and awareness

To describe knowledge, attitudes, and awareness of bipolar disorder detection, ascertainment, and treatment among primary care physicians in a managed care setting.

Quota sampling was used to obtain 102 completed surveys assessing knowledge, attitudes, and awareness of bipolar disorder from a pool of 350 primary care physicians in a large, vertically integrated Midwestern health system from June 2004 through August 2004. Descriptive statistics were used to characterize the distribution of the study results at the physician level.

Primary care physicians are experiencing challenges in diagnosing and treating bipolar patients, who can be difficult and time-consuming. In answering questions about major depressive episode and manic episode symptoms, at least 15% of respondents assessed most symptoms incorrectly. In analyzing 3 case studies, 9%, 11%, and 28% of respondents, respectively, answered all of the questions correctly. When asked which drugs are U.S. Food and Drug Administration-approved for the maintenance treatment of adults with bipolar I disorder, no survey respondent replied correctly for all drugs listed. Importantly, our survey also indicates that these physicians are very willing to refer bipolar patients to psychiatrists for evaluation and treatment, which may help to ensure optimal care.

Opportunities for improvement exist in diagnosing and treating patients with bipolar disorder in the primary care setting, perhaps aided by guidelines, education, and a collaborative care model with psychiatry.
