Infection Rates
in Hospitals
Although public reporting
of infection rates is still not very widespread among
U.S. hospitals, reports do suggest it is a significant
health problem. A report published from Pennsylvania(1)
found that, on average, 12.2 patients per 1,000 acquired
an infection from the hospital at which they were treated.
The average cost to private insurers was $59,915 for
hospitalized patient with an acquired (also called nosocomial)
infection, compared with $8,311 for those who did not.
Obviously this is a public health problem of significant
proportions, and for patients in intensive care and
other critical units the additional burden on the healthcare
system could be astronomical. Conservative estimates
over the last decades have suggested that 5-10% of hospitalized
patients in developed countries acquire nosocomial infections.
However, the actual number could be much higher.
The two most common
microbial agents involved in nosocomial infections are
Methicillin Resistant Staph aureus (MRSA) and Clostridium
difficile, which can be fatal in high risk patients
with compromised immunity. Fortunately, as these infections
get almost exclusively transmitted through contact,
prevention programs that stress barrier methods and
sterile surgical techniques can be highly effective.
Surgical site infections
represent a significant proportion of these infections,
22% according to CDC estimates(2), and as critically
ill patients often have intravenous lines inserted outside
a perfectly sterile operating department atmosphere,
they stand a correspondingly higher chance to acquire
such infections. If not treated aggressively, an additional
14% can get bloodstream infections, which can have higher
case fatality rates.
