Conditions
Summary
This research will explore the effect of arm dominance on vein diameter and whether vein occupation ratio is predictive of DVT. This will inform current practice and assist in the development of an evidence based protocol for vein assessment and choice to enhance patient safety.
Eligibility
Inclusion Criteria1
- All adult patients who are to have a single, double or triple lumen PICC inserted above the ante-cubital fossa region (as per normal practice) by the PICC nurse inserter in the Radiology Department
Exclusion Criteria3
- Inability to provide informed consent due to neurological or language barriers (diagnosis of dementia; uncontrolled mental illness or deficits; inability to read, write or understand English).
- Participants with factors that prevent the consideration of one arm for PICC insertion (lymphoedema, amputation, thrombosis, neck surgery, lymph clearance).
- Participants who are ambidextrous.

Interventions
The diameter of the basilic, brachial and cephalic veins of both arms will be measured using ultrasound prior to PICC insertion. After vein measurement is complete the researcher will ask the participant to indicate their dominant arm. At this point the PICC inserter will chose the largest vein identified on ultrasound to insert the device and the vein used will be measured at the insertion site. PICC diameter will be obtained from manufacturer information to determine the vein occupation ratio. At approximately nine weeks post insertion, the unit record number of each patient will be used to gain access to medical records to gather treatment management information as well as be matched to DVT reports generated by the Radiology Department.
