Prevalence and rates of recognition of depressive disorders in internal medicine outpatient departments of 23 general hospitals in Shenyang, China

Background: One important approach to increasing recognition and treatment rates for depression in urban China is to identify personswithdepressionwhohavecontact withprimaryhealth careservices,mostofwhichareprovidedintheoutpatientdepartments of general hospitals. We aim to assess the prevalence, risk factors and rates of recognition of depressive disorders in internal medicine outpatient departments of general hospitals. Methods: Outpatients with depression among 5312 consecutive attendees at outpatient internal medicine departments of 23 randomly selected general hospitals in Shenyang are identified by a two-stage screening process using the General Health Questionnaire and the Structured Clinical Interview for DSM-IV-TR Axis I Disorders. Charts of subjects with DSM-IV depressive disorders are reviewed to determine if treating clinicians made a diagnosis of depression or prescribed anti-depressant medications. Results: Thecurrentprevalenceofanytypeofdepressivedisorderwas11.0%(95%CI:10.1%–12.1%);andthoseofmajordepressive disorder, dysthymia, and depression not otherwise specified were 3.6% (3.1%–4.2%), 2.8% (2.4%–3.4%), and 4.1% (3.5%–4.8%) respectively. Only 4.0% (2.5%–6.1%) of the depressed patients were identified by the treating clinician and only 3.0% (1.6%–4.9%) were provided with antidepressant medication. Older age, female gender, reporting religious beliefs, low educational level, low income level and widowhood were independently associated with the occurrence of depression. Conclusions: The prevalence of depression in primary care settings in urban China is lower than that reported in most western countriesbuttheriskfactorsfordepressionaresimilar.Theverylowratesofrecognitionandtreatmentarerelatedbothtothelowrates of care seeking for psychological problems and to the high-volume collective model of hospital-based primary care delivery. Increasing the recognition and treatment of depression in Chinese general hospitals will require changing the attitudes of patients and clinicians and, more importantly, altering the structure of care delivery. © 2008 Elsevier B.V.
