Patient selection: cancer patient with intravascular catheter
Risk factors for thrombosis:
(1) peripherally implanted central venous catheter (PICC) line (versus implanted port)
(2) past history of deep vein thrombosis (DVT)
(3) subclavian venipuncture insertion technique
(4) catheter tip not in right atrium or at junction of superior vena cava and right atrium
where:
• A history of catheter-related thrombosis might be an additional risk factor.
• A history of thrombophhilia might be added to the history of DVT.
• Missing data seemed significant for several of the variables.
• Subclavian venipuncture and PICC line are mutually exclusive.
Factors not reaching statistical significance:
(1) triple lumen catheter (odds ratio 3.8, p value 0.10)
(2) technical difficulties (odds ratio 1.8,p value 0.16)
