Question
**Clinical Scenario: Indwelling Medical Device Infection**

A patient in the ICU with an indwelling medical device is presenting with symptoms of invasive infection, specifically fever and chills. Despite being on a course of antibiotics, the condition has not improved.

**Question:**

a) What type of organism do you suspect is causing the infection and why?

**Discussion:**

When considering infections associated with indwelling medical devices, it is important to evaluate the type of organisms that are commonly resistant to antibiotics and capable of forming biofilms. Bacteria such as *Staphylococcus epidermidis* or *Staphylococcus aureus* are frequently implicated due to their ability to adhere to the surfaces of medical devices and resist antibiotic treatment. The persistence of symptoms despite antibiotic therapy may suggest the involvement of a resistant bacterial strain or a biofilm-forming organism. Further laboratory tests, such as cultures and sensitivity testing, are essential for accurate diagnosis and treatment planning.
