The Swiss Iron System SIS was developed between 1998 and 2005. It is a novel concept for diagnostics, therapy and prevention of iron deficiency. The SIS is also the “operating system” of Health Banking. It is a database for the documentation of therapy courses, therapy control and quality management. The therapy quality is published regularly.
The SIS consists of three phases
Saturation therapy: Iron deficiency patients initially need a certain number of infusions to become healthy. This is the case if they have sufficient iron. Two weeks after the saturation therapy the first therapy control takes place (the average ferritin value is then 200 ng/ml).
Observation phase: In the future, the ferritin level will drop again with each menstruation. Three months after the first therapy check-up, a second ferritin test takes place (the average ferritin level is then 140 ng/ml). As soon as the first iron deficiency symptoms appear again in the course of time, the maintenance therapy begins.
Maintenance therapy: On average, the first relapse symptoms begin as soon as the ferritin level falls below 100 ng/ml again. Then the maintenance therapy begins. In order to stay healthy, a woman usually needs two infusions every 4 to 8 months, depending on the amount of menstrual bleeding.
