[Risk Analysis of Catheter-related Bloodstream Infection and Thrombosis in Patients with Blood Diseases Undergoing Peripheral Introvascular Central Catheter (PICC)].

OBJECTIVE: To evaluate the effects of peripheral introvascular central catheters (PICC) on the catheter-associated bloodstream infections (CRBSI) and the formations of catheter-related bloodstream infections.

METHODS: Total of 483 patients with hematologic malignancies admitted in our hospital from January 2013 to December 2016 were enrolled in this study, and 612 PICC catheterization were conducted. The median time of catheterization was 101 d (48 ∼ 184 d) . The incidence rates of CRBSI and CRTC were observed, and the CRBSI and CRTC associated variables were also analyzed.

RESULTS: There were 47 cases of CRBSI (7.7%), and the incidence was 0.59‰ PICC days, and there were 16 cases of CRTC (2.6%), with the incidence of 0.20‰ PICC days. Meanwhile, no other related serious complications found. The Cox regression analysis of CRBSI and CRTC-associated variables showed that the acute leukemia was significantly related with a higher incidence of CRBSI as compared with the other type of disease, however, which was not significantly related with the CRTC.

CONCLUSION: Compared with the traditional CVAD catheterization, the PICC is more safe and effective for the patients with malignant tumors, thus which may become a alternative method for CVAD.
