Notes: **P<0.01; *P<0.05. The independent variables in the generalized liner model were coadded as the following: Years of nursing experience (1–3=1, 4–5=2, 6–10=3, >10=4), Professional titles (Nurse=1, Senior nurse=2, Supervisor nurse=3, Co-chief nurse=4), Education levels (Technical secondary school=1, Junior college=2, Undergraduate=3), Work settings (Community hospital=1, Township hospital=2), Departments (Oncology department=1, Internal medicine department=2, Surgery department=3, Gynecology and obstetrics department=4, Orthopedics department=5), Whether PICC maintenance training was obtained before?(No=0, Yes=1), Whether PICC catheterization certification had been gained?(No=0, Yes=1).

Abbreviation: PICC, peripherally inserted central catheter.
