Acute cardiac care & resuscitationCohort study
Pulmonary Artery Catheter Use and Mortality in the Cardiac Intensive Care Unit
- Multicentre registry cohort study
- annual 2-month snapshots of consecutive CICU admissions
- adjusted analysis
Authors' conclusion
There is wide variation in the use of PACs that is not fully explained by patient level-factors and appears driven in part by institutional tendency. PAC use was associated with higher survival in cardiac patients with shock presenting to CICUs.
