The Case For Maximal Barrier Precautions
It is estimated that a total of 250,000 cases of Catheter Related-Bloodstream Infection (CRBSI) occur each year with an attributable mortality rate estimated at 12%-25% for each infection.1
According to the Institute for Healthcare Improvement (IHI), institutions can virtually eliminate the chief sources of CLABSI with:
According to the IHI, "… maximal barrier precautions means strict compliance with hand hygiene and wearing a cap, mask, sterile gown, and sterile gloves. The cap should cover all hair and the mask should cover the nose and mouth tightly. These precautions are the same as for any other surgical procedure that carries a risk of infection. For the patient, applying maximal barrier precautions means covering the patient from head to toe with a sterile drape, with a small opening for the site of insertion."2
At least two studies of central line insertions have documented the risk of not applying maximal barrier precautions:
Conversely, the adjacent chart demonstrates how institutions can dramatically reduce their rates of CLABSIs by employing maximal barrier precautions as part of the IHI's "CVC bundle": hand hygiene, maximal barrier precautions, chlorhexidine skin antisepsis, optimal catheter site selection and daily review of line necessity, with prompt removal of unnecessary lines.
