Abstract

Objective To describe the prevalence of patients who screen positive for symptoms of bipolar disorder in primary care practice using the validated Mood Disorders Questionnaire (MDQ). Design Prevalence survey. Setting Fifty-four primary care practices across Canada. Participants Adult patients presenting to their primary care practitioners for any cause and reporting, during the course of their visits, current or previous symptoms of depression, anxiety, substance use disorders, or attention deficit hyperactivity disorder. Main outcome measures Subjects were screened for symptoms suggestive of bipolar disorder using the MDQ. Health-related quality of life, functional impairment, and work productivity were evaluated using the 12-Item Short-Form Health Survey and Sheehan Disability Scale. Results A total of 1416 patients were approached to participate in this study, and 1304 completed the survey. Of these, 27.9% screened positive for symptoms of bipolar disorder. All 13 items of the MDQ were significantly associated with screening positive for bipolar disorder (P < .05). Patients screening positive were significantly more likely to report depression, anxiety, substance use, attention deficit hyperactivity disorder, family history of bipolar disorder, or suicide attempts than patients screening negative were (P < .001). Health-related quality of life, work or school productivity, and social and family functioning were all significantly worse in patients who screened positive (P < .001). Conclusion This prevalence survey suggests that more than a quarter of patients presenting to primary care with past or current psychiatric indices are at risk of bipolar disorder. Patients exhibiting a cluster of these symptoms should be further questioned on family history of bipolar disorder and suicide attempts, and selectively screened for symptoms suggestive of bipolar disorder using the quick and high-yielding MDQ.
