In academic trauma units, senior physicians (secondary operators) placing central venous catheters showed lower adherence to maximum barrier precautions (MBP) than trainees. This highlights a need for improved sterile technique education for experienced clinicians to enhance patient safety.

Area of Science:

  • Medical Procedures
  • Infection Control
  • Surgical Safety

Background:

  • Central venous catheters are frequently placed by multiple operators in academic trauma units.
  • Limited data exist on adherence to sterile practices during these procedures.

Purpose of the Study:

  • To evaluate physician adherence to maximum barrier precautions (MBP) during central venous catheterizations in a trauma resuscitation unit.
  • To compare MBP compliance between primary (trainees) and secondary (mentors) operators.

Main Methods:

  • Prospective video analysis of 144 central venous catheterizations in a trauma unit.
  • Recorded primary and secondary operator numbers and adherence to MBP (sterile gown, gloves, drape, cap, mask).
  • Procedures stratified by urgency: emergent, semi-emergent, and elective.

Main Results:

  • For elective central venous catheter placements, 88% of primary operators used MBP compared to 69% of secondary operators (p < 0.01).
  • Frank contamination occurred in 9% of elective cases involving a secondary operator.
  • The subclavian vein was the most common site for elective placements (73%).

Conclusions:

  • Experienced clinicians (secondary operators) demonstrated lower adherence to MBP than trainees during central venous catheter placement.
  • There is a need to reinforce and educate senior clinicians on consistent use of sterile practices.
  • Improving MBP compliance among all operators is crucial for reducing infection risk in trauma patients.
