This case is about bacteria being transferred from patient to patient in a hospital. It seemed like this could happen because they got left behind in a medical device, even though the device was cleaned and disinfected after each use. It took a thorough Forensic Engineering Investigation to discover what happened. Later, it appeared that this problem occurred not only in this hospital, but in hospitals all over the world. In this video, you will learn how the infections were discovered and what instrument seemed to cause them.

(This Module has been put together using elements of several cases that we had to investigate in the past and that had the same outbreak pattern and similar cause. In these cases the involved hospitals and manufacturers all cooperated really well to find the cause and fix it. So in order to avoid unnecessary shaming of these well-willing parties, we only use fictive names, locations, numbers and years… but still, it’s all based on real cases.)
