Introduction: Since breast imaging requires very close contact with patients, a protocol is needed to perform safe daily screening activities during the COVID-19 pandemic. Materials and methods: Patients were triaged and separated into three different clinical scenarios by performing a telephone questionnaire before each diagnostic exam or a nasopharyngeal swab before every recovery. Specific procedures for each scenario are described. Results: From July to October 2020, 994 exams were performed. A total of 16 cancers and 7 suspected COVID-19 patients were identified. No medical staff were infected. Conclusion: This protocol is an example of the practical use of guidelines applied to a breast unit to assist specialists in preventing COVID-19 infection and optimizing resources for breast cancer diagnosis.

Lay abstract On March 11th, 2020, the WHO officially declared the COVID-19 infection pandemic. Since breast cancer represents the most frequent cancer in women of all ages, and breast imaging examinations require very close contact with patients, a protocol was designed to optimize the management of patients and healthcare workers, performing strict COVID-19 screening and avoiding any impairment of survival of patients with breast cancer. Patients were separated into three different clinical scenarios (non-COVID-19 patients, suspected COVID-19 patients and confirmed COVID-19 patients) by performing a telephone questionnaire before each diagnostic exam or a nasopharyngeal swab before every recovery. Specific procedures for each scenario are described. Confirmed or suspected patients are rescheduled if not urgent. From July to October 2020, 994 exams were performed. A total of 16 cancers and 7 suspected COVID-19 patients were identified. No medical staff were infected. This study demonstrates efficacy in terms of continuity in the provision of an essential level of care in a breast cancer screening and ambulatory setting, providing an example of the practical use of guidelines applied to a breast unit, to assist specialists in preventing COVID-19 infection and optimizing resources for breast cancer diagnosis.
