[The actual issues of improvement of organization of screening of skin neoplasms in out-patient conditions].

The skin malignant neoplasms constitute one of significant problems of public health. The increasing of morbidity and mortality of melanoma and other types of skin cancers is registered. The early detection of disease assures mortality decreasing and increases survival of patients. The purpose of the study is to develop optimal model of organizational and preventive measures of early diagnostic of malignant skin tumors. The comprehensive study was carried out, which included assessment of survey of patients using questionnaire "Melanoma Diagnosis Day". Also it included identification of level of awareness of physicians about screening, medical records of patients during COVID-19 pandemic, risk groups identification and effectiveness of selecting patient for screening. The total number of observations is 21 581. The selective and continuous observation method was applied and parametric and non-parametric methods as well. The study determined that during COVID-19 pandemic in 2020, there was significant reliable uncompensated decrease in the number of patients with diagnosis of ICD D23, L82, C44 and decrease in the number of detected diseases. The melanoma, basalioma and other skin malignant neoplasms are reliably more common in patients of medium-high risk group, aged 60 years and older and in persons sunburned at the age of 18 years. The assignation of separate specialist to diagnose skin neoplasms allows statistically reliably increase rate of morphological confirmation of malignant neoplasms as compared to common reception by dermatologist. The sociological survey of physicians revealed statistically reliable difference in knowledge between dermatovenereologists, oncologists and physicians of other specialties concerning screening issues. The results of the study permitted to develop complex of organizational measures to improve screening. The model of organizational and preventive measures for early diagnostic of skin malignant tumors in outpatient conditions was proposed.
