Hierarchical multiple logistic regression analysis was performed. Model 1 included age, sex, BMI, and care bundle intervention. Model 2 included Model 1 and hyperosmolar solutions, C-reactive protein, total un-used time, and insertion anatomical site (compared with another site). Model 3 included Model 1 and C-reactive protein, total unused time, and insertion anatomical site (compared with another site) and number of catheterizations.
OR: odds ratio. Model 3: Hosmer-Lemeshow test, p = 0.603.
