초록
The purpose of this study is to investigate bacterial contamination on mammography equipment(face shields, compression Paddles and detectors, handles) due to physical contact. Given the high infection risk from skin surface bacteria during breast cancer screenings, we measured contamination levels before and after disinfection, identifying detected bacterial strains. Equipment from two medical facilities was examined, focusing on specified parts. Samples were collected pre-disinfection, post-disinfection(before and after daily examinations), and analyzed via plate culture. Results highlighted significant bacterial presence, especially pre-disinfection and from airborne bac- teria on equipment surfaces. compression Paddles and Detectors areas showed higher contamination, emphasizing the need for focused disinfection. Disinfection is crucial before mammography to prevent infections from airborne bacteria. Harmful bacteria were notably detected in the compression Paddles and Detectors area, necessitating focused disinfection of the compression Paddles and Detectors part. Additionally, the face shields and handles area, being at high risk for infections, also showed the presence of harmful bacteria, indicating the need for disinfection in that area as well. Alcohol swabs proved more effective than sprays for airborne bacteria removal, with the most bacteria detected post-examination without disinfection. This supports alcohol-based disinfection's critical role. We propose that removing airborne bacteria is essential, mammography equipment should be disinfected focusing on cer- tain areas, and disinfection should be performed with alcohol swabs before, during, and after examinations.
