Description of intervention(s) / exposure
This is a study review ulilitsing a PICC line with tapper that is larger proximally. Usually the line is inserted and it is decided by the inserter whether to use the larger proximal part of the line or not. This study is going to compare pateints that have had the larger part of the line inserted into the vessels with patients who have not had the tapper inserted. Both patient groups are going to be followed up 7 days post insertion with ultrasound. This study is a pilot comparative study.
Intervention code [1] 284864 0
Not applicable
Comparator / control treatment
Adult patients not receiving reverse tapered device, no tapper will be inserted into this patient population.
Control group

Primary outcome [1] 287131 0
To determine whether utilising reverse taper catheter increase patients risk of thrombosis. The outcome will be assessed using ultrasound to scan the patients and record outcomes
Timepoint [1] 287131 0
7 days post insertion
Secondary outcome [1] 297453 0
To determine whether there is a reduction in catheter migration. Seven days post insertion the catheter will be observed for migration at the follow up ultrasound scan.
Timepoint [1] 297453 0
7 days post insertion
