Difficulty: MediumInfection Control and Hospital-Acquired Conditions

A 62-year-old woman is evaluated in the surgical intensive care unit for a new-onset fever. She underwent a complex exploratory laparotomy for a perforated viscus 6 days ago. Postoperatively, she required significant fluid resuscitation and vasopressor support, prompting the placement of a central venous catheter in the right internal jugular vein. She has been weaning off support, but today her temperature is 38.9°C (102°F), blood pressure is 94/62 mmHg, and heart rate is 114/min. The catheter insertion site shows no erythema or purulent drainage. Leukocyte count is 16,500/mm³. Paired blood cultures drawn from the central line and a peripheral vein are pending. The medical director of the ICU is currently implementing a quality improvement initiative to decrease the incidence of this patient's suspected hospital-acquired condition. Which of the following practices should be strictly enforced as part of the evidence-based insertion bundle to most effectively prevent this complication?

  1. Application of maximum sterile barrier precautions during catheter insertionAnswer
  2. B
    Administration of systemic prophylactic antibiotics 30 minutes prior to insertion
  3. C
    Routine replacement of the central venous catheter over a guidewire every 7 days
  4. D
    Preferential utilization of the femoral vein instead of the subclavian vein for venous access
  5. E
    Routine culturing of the catheter tip upon discontinuation in all patients

Answer

The correct practice is the application of maximum sterile barrier precautions during catheter insertion.
The application of maximum sterile barrier precautions (including a sterile gown, sterile gloves, a surgical cap, a mask, and a large full-body sterile drape) is a strictly enforced, highly effective component of the central line insertion bundle. Combined with strict hand hygiene, chlorhexidine skin antisepsis, optimal site selection (subclavian preferred), and daily evaluation for line removal, this bundle has been proven to significantly reduce the incidence of Central Line-Associated Bloodstream Infections (CLABSI).

Step-by-Step Solution

1
Identify the patient's likely diagnosis based on the clinical presentation.
The patient has a new fever and leukocytosis 6 days after placement of a central venous catheter, which is highly suspicious for a central line-associated bloodstream infection (CLABSI).
Recognizing the hospital-acquired condition is necessary to determine the appropriate preventive quality improvement measures.
2
Review the components of the standard evidence-based CLABSI prevention bundle.
The core components are hand hygiene, maximum sterile barrier precautions, chlorhexidine skin antisepsis, optimal catheter site selection, and daily review of line necessity.
The question asks specifically for a practice that is part of the evidence-based insertion bundle.
3
Evaluate the given options against the established CDC/IDSA guidelines.
Maximum sterile barrier precautions is the only option that represents a correct, proven bundle component.
Distinguishing proven preventive measures from outdated or harmful practices is critical for patient safety.
