One of the objectives of the Federal Project «Fighting Cancer» is to achieve «The proportion of malignant neoplasms detected at early stages, Percentage.» One method to achieve the set goals is to improve the efficiency of preventive medical examinations and screenings of certain adult population groups. The study aims to provide a methodological rationale for calculating the efficiency indicators of preventive medical examinations and screenings of certain adult population groups in terms of detecting malignant neoplasms. Materials and methods. For conducting the study, we used normative legal documents regulating the procedures for conducting preventive medical examinations and screenings of certain adult population groups, as well as industry-specific statistical report forms № 131/o «Information on conducting preventive medical examinations and screenings of certain adult population groups» from 11 subjects of the Northwestern Federal District for the period 2017–2022. Results. According to the analysis of the indicator «The share of residents of the Russian Federation subjects undergoing PME (Preventive Medical Examination) and SCS (Screening for Certain Groups) compared to the number of residents fitting the criteria for PME and SCS», this indicator has practically not changed over the period from 2017 to 2022, being 0,41 in 2017 and 0,42 in 2022. The coverage by preventive examinations and screenings of certain population groups in the Russian Federation subject in the Northwestern Federal District from 2017 to 2022 decreased from 0,92 to 0,75 of what was due. When calculating the actual coverage by preventive examinations and screenings of certain adult population groups in the Northwestern Federal District, the indicator slightly decreased from 0,37 in 2017 to 0,32 in 2022. The «overall» contribution of preventive medical examinations and screenings of certain adult population groups in the Northwestern Federal District slightly increased from 0,11% in 2017 to 0,14% in 2022. When analysing the «crude» index of the contribution of PME and SCS in detecting malignant neoplasms from 2017 to 2022, an increase from 3,34% to 7,6% is noted. The standardised contribution of preventive examinations and screenings of certain adult population groups to the diagnosis of breast cancer malignant neoplasms increased from 3,7% in 2017 to 8,5%, and the diagnosis of malignant neoplasms of colon, rectum, and anal canal (C18-C20) for the same period increased from 4% to 7,9%. Conclusion. Regardless of which indicator is used to calculate the efficiency of conducted preventive measures, manual data entry and the formation of statistical forms 131/o must be stopped. Manual data entry can lead to data distortion and introduce significant fluctuations in indicators when comparing the same indicator among different subjects of the Russian Federation.
