  • The independent variables in the generalised linear model were coadded as follows: gender (female=0, male=1), age (<25=1,25–34=2,35–44=3,≥45=4), professional title (nurse=1, senior nurse=2, supervisor nurse=3, cochief nurse=4), education level (technical secondary school=1, junior college=2, undergraduate=3, postgraduate=4), work setting (county hospital=1, municipal hospital=2, provincial hospital=3), whether PICC maintenance training was obtained before? (no=0, yes=1)
