Multivariate/Adjusted Analysis for Effect of Line Type on Thrombosis Events.
| MC Adjusteda | PICC Adjusteda | AOR (95% CI)b | P Value | |
|---|---|---|---|---|
| Catheter-related events | ||||
| Thrombosis (DVT or SVT) | 22.30% | 12.34% | 2.04 (1.46-2.86) | <.0001 |
| DVT | 12.53% | 6.85% | 1.95 (1.28-2.97) | .0019 |
| SVT | 5.56% | 2.91% | 1.96 (1.18-3.25) | .0090 |
| Contralateral events | ||||
| Thrombosis (DVT or SVT) | 4.04% | 4.40% | 0.91 (0.50-1.66) | .7706 |
| DVT | 1.46% | 1.59% | 0.91 (0.39-2.13) | .8360 |
| SVT | 3.66% | 4.05% | 0.90 (0.43-1.90) | .7814 |
| PE events | ||||
| PE | 7.19% | 4.88% | 1.51 (0.74-3.09) | .2606 |
Abbreviation: AOR, adjusted odds ratio; CI, confidence interval; DVT, deep vein thrombosis; MC, midline catheter; PE, pulmonary embolism; PICC, peripherally inserted central catheter; SVT, superficial venous thrombophlebitis.
aThe percentages refer to the model-adjusted predicted probabilities of developing a thrombosis event.
bAOR refers to the model-adjusted odds of developing a thrombolytic event in MCs relative to the odds of developing a thrombosis event in PICCs. The model is adjusted for the effect of age, sex, lumen/size, location, DVT/PE history, number of attempts, line side, and indication.
