title: [A systemic concept of individual health status from the standpoint of practical medicine. Part I. Theoretical aspects].
abstract: The paper presents the system concept of individual health in the context of practical medicine, which includes the definition of this widely use, the system forming of its understanding in the physician-patient system, the phasic pattern of individual health as transient prenosological and postnosological entities, the traditional quantitatively diagnostic and integrally quantitative principles in the evaluation of the level of individual health. By using these principles and taking into account specialization in the state public health care, the authors provide evidence for that it is expedient to identify the mental, physical, physiological, biochemical, clinical, and somatic status of a patient. The phasic pattern of individual health substantiates the concept of prenosological staging of the development of chronic diseases of specific and nonspecific genesis and the expediency of identifying primary and secondary chronic diseases of any etiology. In the authors' opinion, it is expedient to consider prenosological diagnosis, its categorical and terminological aspects, differential diagnosis, treatment, prevention, and rehabilitation of patients with prenosological conditions to be the general trend of scientific-and-practical developments in the area of individual health. Methodologically, it is necessary to use of the entire store of methods of integrative and occupational medicine, particularly in the field of etiological diagnosis by risk and anti-risk factors, of those of functional diagnosis using exercise tests and of clinical diagnosis of prenosological entities.
