deviceassociated

Device-associated refers to health care–associated conditions that arise in relation to the use of medical devices. In medicine, the term is commonly used to describe infections or complications linked to implanted or indwelling devices, such as catheters, endotracheal tubes, or prosthetic implants.

Device-associated infections occur when microorganisms colonize a device surface, frequently forming biofilms that resist antibiotics and immune clearance. The risk is influenced by device type, duration of use, patient health status, and adherence to aseptic technique during insertion and maintenance.

Common examples include catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP), prosthetic joint infections, and other implant-associated infections.

Diagnosis typically combines clinical assessment with microbiological testing and device evaluation. Management often requires removal or replacement of the device when feasible, along with targeted antimicrobial therapy. In prosthetic infections, surgery and biofilm-active antibiotics may be necessary.

Prevention focuses on minimizing device use, ensuring timely removal when no longer needed, strict sterile technique, and care bundles for insertion and maintenance. Device-associated infections pose significant risks to patients, increase hospital stays and costs, and contribute to antimicrobial resistance concerns.
