title: Rates of detection of mood and anxiety disorders in primary care: a descriptive, cross-sectional study.
abstract: OBJECTIVE
  To determine the incidence of major depressive disorder, bipolar disorder, panic disorder, social anxiety disorder, and generalized anxiety disorder and to assess their detection rates in the Canadian primary care setting.
  
  
  METHODS
  The descriptive, cross-sectional study was conducted in 7 primary care clinics in 3 Canadian provinces, Ontario, British Columbia, and Nova Scotia, from December 6, 2005, to May 5, 2006. Patients in clinic waiting rooms who consented to participate in the study were administered the Mini International Neuropsychiatric Interview (MINI) (N = 840). These patients' medical charts were then reviewed for evidence of previous diagnosis of a mood or anxiety disorder. Misdiagnosis was defined as cases for which a diagnosis was reached on the MINI but not in the patient's chart.
  
  
  RESULTS
  Of the 840 primary care patients assessed, 27.2%, 11.4%, 12.6%, 31.2%, and 16.5% of patients met criteria for major depressive disorder, bipolar disorder, panic disorder, generalized anxiety disorder, and social anxiety disorder, respectively. Misdiagnosis rates reached 65.9% for major depressive disorder, 92.7% for bipolar disorder, 85.8% for panic disorder, 71.0% for generalized anxiety disorder, and 97.8% for social anxiety disorder.
  
  
  CONCLUSIONS
  With high prevalence rates and poor detection, there is an obvious need to enhance diagnostic screening in the primary care setting.
