This confronted all clinics with completely new and difficult challenges. In accordance with the official requirements, pandemic officers were appointed at the Kempten Clinic and a clinical management team was established. It was important to keep a relevant proportion of employees off duty at all times, and thus to have a constant reserve available in the event of expected infection-related absences of physicians and nurses. These structural changes were complemented by staff briefings and the creation of a training program on the subject of COVID-19. Within a very short time, algorithms were designed and defined how to manage patients presenting in the hospital or in the emergency room. The surgical program was limited to operations that could not be postponed, such as extrauterine pregnancy or adnexal torsion, and oncological diagnoses without the possibility of primary systemic therapy. In the case of breast cancer, however, therapy was started in all cases in which primary systemic therapy (PST), whether cytotoxic or endocrinological, appeared possible and indicated. As of 1 April 2020, more than 50% of the usable beds in the Kempten Clinic were empty.
