title: The importance of quality control in the implementation of breast cancer screening program in the Health Center Zemun.
abstract: OBJECTIVE
  To investigate whether the differences in implementation between opportunistic and organized breast cancer screening affect the results, as well as the significance of quality control during the implementation of organized breast cancer screening.
  
  
  METHODS
  Testing was performed in 2013 (opportunistic screening) and 2014 (organized screening) in the Health Centre Zemun. This included female population aged 50-69 years, belonging to the target population according to the national breast cancer screening programs. The Health Centre Zemun database of insured patients from the National Health Insurance Fund of the municipality of Zemun and Surcin was used for the evaluation of the screening performance. Statistical data processing was done with the statistical package SPSS-20.0.
  
  
  RESULTS
  There was a highly significant difference (p=0.000) in the implementation of opportunistic and organized screening, whereby the response of women in organized screening was much greater (11.48%) than of the women responding to opportunistic screening (0.27%). The low response of women noticed in the summer in organized screening was attributed to the fact that the majority of women in Serbia take their holidays in that period.
  
  
  CONCLUSIONS
  Performance and quality of screening depends on the control of all segments of the activities carried out in the screening process. Previous experience in organizing and controlling the quality of the implementation of screening can serve as a proven model, which by a multidisciplinary approach in practice can provide a better and safer healthcare.
