AHTs were calculated using linear models, with each value demonstrating annual trend of mean number of patients in different conditions.
AHT, annual historical trend; BSI, bloodstream infection; CI, confidence interval; OR, odds ratio; PICC, peripherally inserted central catheter.

Uncorrected bilateral chi-square tests, ORs, CIs and AHTs were calculated by R software (https://www.r-project.org/); p ≤ 0.05 was considered statistically significant.
