[The study of the prevalence of depressive disorders in primary care patients in Poland].
Studies performed in recent years in different countries suggest a considerable prevalence of depressive disorders in primary care patients. The aim of our study was the assessment of depressive disorders among primary care patients in Poland.


METHODS
Three-hundred thirty-three randomly chosen private and public primary care clinics from the whole country took part in the study. In each centre, 20 or 25 patients aged 18-65 years coming for a regular visit were asked to participate in the study. All patients filled in the Beck Depression Inventory (BDI). Additionally, basic demographic data and information on the presence of chronic somatic diseases were collected. Those patients who scored 12 or more points on BDI (cut-offpoint for depression in Poland) were evaluated by a primary care physician for presence of a depressive disorder upon the ICD-10 criteria and subsequently referred for a psychiatric consultation to the nearest psychiatric outpatient clinic for establishing plausible diagnosis of depression.


RESULTS
Out of 7360 patients approached, 7289 (95.5%) agreed to participate. The mean age of the sample was 43.3 +/- 13.2 and 71% were females. Forty one percent of patients (2985) had 12 or more points on the BDI and were referred for a psychiatric evaluation. Only half of them came for a psychiatric consultation. Depressive disorder was recognised in 906 patients. Estimated prevalence of depressive disorders in the whole sample was 23.3%. The patients in whom depressive disorders were confirmed by psychiatric assessment had significantly more often hypertension, ischaemic heart disease, anaemia, stroke and hypothyroidism.


CONCLUSIONS
The results obtained show that depressive disorders' prevalence in primary care patients in Poland is significant. The patients who had depressive disorders significantly more often than patients without depression suffered from some somatic diseases. In light of the results, both recognition and adequate treatment of depressive disorders in primary care patients should be regarded as equally important as the recognition and treatment of cardiovascular diseases or other common somatic illnesses.
