Mechanical adverse events associated with central vascular catheters (CVCs)
Centers for Medicare & Medicaid Services (CMS), Medicare Patient Safety Monitoring System (MPSMS).
2.28 Percent of central vascular catheter placement with associated mechanical adverse events, United States, 2002 and 2003.
- CMS, MPSMS, inpatient medical records: for abstracted data related to the index hospital stay.
- CMS Medicare Administrative Data: used for 30-day post-procedure mortality.
All instances in records from the MPSMS sample of placement of at least 1 vascular access device terminating at, or close to, the heart or in 1 of the great vessels. The following are considered great vessels for this measure: aorta, vena cava, brachiocephalic veins, iliac vein, internal jugular veins, and subclavian veins.
Subset of the denominator with CVC-associated mechanical adverse events.
A CVC-associated mechanical adverse event is defined as the presence in the medical record of at least 1 of the following: allergic reaction, tamponade, perforation, pneumothorax, hematoma, shearing off of the catheter, air embolism, misplaced catheter, thrombosis/embolism, knotting of the pulmonary artery catheter, and certain other events.
In order to attain greater consistency between 2002 and 2003 data, the analytic approach used to produce these tables differs from earlier years of the NHQR.
