Types of Healthcare-Associated Infections
-
Surgical site infections (SSIs)
Surgical site infections (SSIs) initiated during invasive procedures can require additional and/or extended treatment. Despite the best efforts of healthcare facilities to maintain safe surgical environments, surgical site infections result in up to $10 billion in treatment costs every year in the U.S. alone.
* 780,000 out of 30 million surgical procedures performed annually in the U.S. result in SSI.1
* In the United Kingdom, the estimated direct costs for a patient who has developed a surgical site infection are between €2,265 and €2,518.2
* According to a study in the Netherlands, SSIs result in 5.8 to 17 extra days of hospitalization.3
* In France, approximately 11% of surgical patients acquire a surgical site infection.4Some common causes of SSI are:
* Complications from surgical hypothermia
* Contamination of the incision area by skin flora
* Bacterial cross–contamination
* Surgical instrument contamination1 Cook, R. “Hospitals learn simple, cheap steps can prevent infections,” San Francisco Chronicle, May 18, 2004; F1.

Cross Contamination
Unfortunately even with the best of intentions, healthcare workers do not always wash and disinfect their hands as often as they should. This less than perfect hand hygiene performance can pose a serious risk to patients because as stated by Dr. Julie Gerberding, director of the Centers for Disease Control (CDC), “Clean hands are the single most important factor in preventing the spread of dangerous germs and antibiotic resistance in healthcare settings.”1
While the use of gloves does not eliminate the need for hand hygiene, likewise, the use of hand hygiene does not eliminate the need for gloves. Gloves reduce hand contamination by 70 percent to 80 percent, prevent cross–contamination and protect patients and healthcare personnel from infection.
The importance of gloves, masks, and other personal protective apparel cannot be overestimated in preventing infection in healthcare settings. They, along with hand hygiene, are the first line of defense in preventing the spread of infection from person to person within healthcare settings.

Ventilator–associated pneumonia (VAP)
Ventilator–associated pneumonia (VAP) is one of the top three infection concerns of clinicians today; it may account for up to 60% of all deaths from healthcare-associated infections (HAIs) in the U.S.1 Other key U.S. statistics include:
* Approximately 8–28% of critical care patients develop VAP2
* Healthcare–associated pneumonia patients have a mortality rate of 20% to 33%1
* VAP increases patient time in the ICU by 4 to 6 days1
* Each incidence of VAP is estimated to generate an increased cost of $20,000 to $40,0001VAP is a global issue. In Germany, between 2001 and 2005, 5.72% of ICU patients developed VAP.3 According to recent statistics, 9.2% of ICU patients in France develop ICU–acquired pneumonia.4 And in the UK, hospital–acquired lower respiratory tract infection adds an average of 12 days to hospital stays, at an average additional cost of $4,149 per patient.5
The CDC’s National Nosocomial Infection Surveillance System (NNIS) reported that in 2002, patients receiving continuous mechanical ventilation had 6–21 times the risk of developing healthcare–associated pneumonia compared with patients who were not receiving mechanical ventilation. Because of this tremendous risk, in the last two decades, most of the research on healthcare–associated pneumonia has been focused on VAP.6
