Vascular Access Devices
Infusion medications are delivered using a vascular (or venous) access device (VAD). In the hospital most medications are administered using short-term catheters that must be frequently "rotated." Advances in technology have led to the introduction of a wide range of VAD options such as PICC catheters.
These long-term VADs are inserted in the hospital prior to discharge to home and provide for greater levels of patient independence in therapy self-management.
Blood samples can also be obtained through the access device. Ongoing lab results are required to monitor the progress of the home infusion therapy.
