Abstract BACKGROUND: Peripherally inserted central catheters (PICC) are increasingly used in hospitalized patients. The benefit can be offset by complications such as upper extremity deep vein thrombosis (UEDVT). METHODS: Retrospective study of patients who received a PICC while hospitalized at the Methodist University Hospital (MUH) in Memphis, TN. All adult consecutive patients who had PICCs inserted during the study period and who did not have a UEDVT at the time of PICC insertion were included in the study. A UEDVT was defined as a symptomatic event in the ipsilateral extremity, leading to the performance of duplex ultrasonography, which confirmed the diagnosis of UEDVT. Pulmonary embolism (PE) was defined as a symptomatic event prompting the performance of ventilation-perfusion lung scan or spiral computed tomography (CT). RESULTS: Among 777 patients, 38 patients experienced 1 or more venous thromboembolisms (VTEs), yielding an incidence of 4.89\%. A total of 7444 PICC-days were recorded for 777 patients. This yields a rate of 5.10 VTEs/1000 PICC-days. Compared to patients whose PICC was inserted in the SVC, patients whose PICC was in another location had an increased risk (odds ratio = 2.61 [95\% CI = 1.28-5.35]) of VTE. PICC related VTE was significantly more common among patients with a past history of VTE (odds ratio = 10.83 [95\% CI = 4.89-23.95]). CONCLUSIONS: About 5\% of patients undergoing PICC placement in acute care hospitals will develop thromboembolic complications. Thromboembolic complications were especially common among persons with a past history of VTE. Catheter tip location at the time of insertion may be an important modifiable risk factor.
