The sample of 2894 of primary care patients were studied within the Kiev out-patient health care facilities. 816 patients (28,2% ) were diagnosed with psychiatric and behavioral disorders with the prevalence of range of affective symptoms (anxiety, phobic and depressive) in 70% cases. It was drawn up "generalized social and clinical portrait" of primary care patient with psychiatric and behavioral disorders: female patient with age from 41 to 60 years, with high school or college diploma, single, living alone in private apartment, white-collar worker or retired, presenting mostly neurologic (33,8%), cardiologic (28,7%) or gastrointestinal (16,5%) complains. According to the prevalent component of the affective symptoms range were described the following states - anxiety 945%), fatigue (asthenia) (40,0%) and dysphoria (15,0%). According to the prevalent general medical conditions - algetic (62%), dientsefalny (20,0%) and agripnia (18,0%) syndromes were picked out. Correlations between peculiarities of psychiatric disturbances of out-patient primary care patients and specifics of general medical conditions were found. Neurologic patients have comorbid asthenic states, autonomous nervous system disturbances and anxious depression; cardiologic patients differ with obsessive disturbance and phobic anxiety; patients with gastrointestinal complains tend to have hypohondric and fatigue states. It have been scientifically justified the model of "integral aftercare" for primary care patients with the conceptual basis of psychosomatic day care facility incorporated in the structure of general hospital with the various outpatient secondary care departments. There were developed: 1) algorithm for the GP for working with the patients with comorbid psychiatric and behavioral disturbances: 2) questionery for screening the risk of psychiatric disorders in the patients in primary care; 3) algorithm for the arrangement of a ll-round mental health care for primary care patients within the structure of general hospital in team cooperation of internists and psychiatrists; 4) the program of psychoeducation that can be implemented in GPs' practice for work with their patients and relatives. Implementation the system mentioned above may improve the effectiveness and outcome of primary and secondary general care through the reduction of clinical symptoms, preventing relapse, promoting treatment adherence (both psychotropics and somatropics) and improvement of social functioning and interpersonal relations within the family. Key words: psychiatric disorders, primary care, diagnosis, treatment.
