Association between catheter appropriateness and risk of complications

	Appropriate PICC placement (n=15 128), no. (%)		Inappropriate PICC placement (n=23 464), no. (%)		OR (95% CI)	P value
Occlusion	572	3.78%	2998	12.78%	0.25 (0.21 to 0.29)	<0.001
CLABSI	136	0.90%	490	2.09%	0.61 (0.46 to 0.81)	0.001
VTE	214	1.41%	925	3.94%	0.40 (0.33 to 0.47)	<0.001
All complications	884	5.84%	4130	17.60%	0.29 (0.25 to 0.34)	<0.001

Mixed-effects logistic model including hospital random effects and year fixed effects. All models control for patient characteristics (sex, age, Charlson Comorbidity Score, BMI, history of cancer, indication of current CVC at time of PICC placement, line duration).

BMI, body mass index; CLABSI, central line-associated bloodstream infection; CVC, central venous catheter; PICC, peripherally inserted central catheter; VTE, venous thromboembolism.
