Risk factors for arterial catheter failure and complications during critical care hospitalisation: a secondary analysis of a multisite, randomised trial
Authors' conclusion
AC failure is common with ultrasound-guided insertion associated with lower failure rates.

- Population
- Adult ICU patients with an arterial catheter (AC)
- Participants
- 664 patients
- Primary endpoint
- All-cause AC failure
Methodological detailsCox proportional hazards and competing-risk models

Primary result
As reported in the abstract
- AC failure
- 173 (26%)
- AC failure incidence rate per 1000 catheter days
- 37
- Ultrasound-assisted insertion, all-cause failure
- adjusted HR 0.43 (0.25, 0.76) (95% CI)
- Age 60-74 years vs 15-59 years, AC failure
- HR 0.63 (0.44 to 0.89) (95% CI)
- Age 75 + years vs 15-59 years, AC failure
- HR 0.36 (0.20, 0.64) (95% CI)
