title: Agreement between physicians and liaison psychiatrists on depression in old age patients of a general hospital: influence of symptom severity, age and personality.
abstract: Comorbid depressive episodes are common among general hospital inpatients. However, existing evidence shows that depression is often poorly recognized in patients aged over 60 years. The aim of the study was first to determine the degree of agreement between primary care physicians' and liaison psychiatrists' evaluation of depression, and second, to analyze how patients' clinical presentation and personality traits influence this degree of agreement.
  
  
  
  Agreement was defined as the matching of the physicians' initial referral for depressive mood and the actual diagnosis of a major depressive disorder evaluated by the consultation-liaison service in 148 inpatients aged 60+ years. Nature and severity of psychiatric symptoms were rated on the HoNOS65+ scale and patients' personality traits were assessed with the Big Five Inventory.
  
  
  
  Forty percent of the patients referred for depressive mood were indeed diagnosed with major depression. Agreement between physicians and psychiatrists was most likely in patients with more severe depressive symptoms and younger age. In contrast, risk for non-agreement was increased for patients with more open personalities, yet lower levels of neuroticism, who were referred for depressive mood even though they presented another or even no psychiatric disorder.
  
  
  
  These data reveal that the detection of late-life depression in general hospitals may be critically influenced by age, symptoms severity and personality traits.
