By simply following 5 simple steps, Michigan hospitals have been able to virtually eliminate infections related to central line catheters, according to research published in the British Medical Journal.
Here is some information about hospital-acquired infections:
. They are a major problem in both the developing and developed world, affecting an estimated 8.7% of hospitalized patients, overall.
. They are a major cause of death among hospitalized patients worldwide
. At any given time, about 1.4 million people worldwide are suffering from problems related to infections they acquired while in hospital
Researchers from Johns Hopkins University in Baltimore followed the infection rates of more than 100 Michigan-based intensive care units (ICUs) after they instituted a 5-item checklist system developed at Hopkins for the placement of a central line catheter, which threads through a vein to reach in or near the heart. The five steps are: wash hands; wash patient's skin with an antimicrobial solution; wear a mask, hat, gown, and gloves; cover the patient in sterile drapes; avoid placing the catheter in the groin area; and remove it as soon as possible, even if it may need to be replaced in the future.
Before instituting this simple checklist, about three central line infections occurred for every 1,000 hours that patients were attached to one of these catheters. Eighteen months after instituting the checklist system, infection rates were virtually zero, and they remained virtually zero for up to three years in all participating institutions.
We spoke with Dr. Peter Pronovost, the principal investigator of this study, who offered some further insight.
Today's research demonstrates how carefully-followed infection-control steps, which are simple and inexpensive, can drastically reduce hospital infection rates. |
