We can expect to live at least 26 years longer
today than our grandparents did 90 years ago. A number of factors have contributed
to our longer life expectancy, among them medical innovation, nutritional
improvements, and sociocultural changes. The effects of increased sanitation
and the role of disinfection have also been very important.
Hospital Sterilants and Disinfectants
Infection control in the modern hospital environment
depends heavily upon the use of a variety of specialized antimicrobial
formulations. In addition to the cleaning and disinfectant solutions used
in general housekeeping, there are various formulations used for especially
demanding tasks such as operating room protection and sterilization or
high-level disinfection of delicate and heat-sensitive medical devices.
The appropriate and careful use of these products is a major factor in
infection control.
Since bacteria, viruses and fungi cannot be
seen with the naked eye, extensive testing requirements and government
review assure the validity of product claims. Depending on their use,
antimicrobial products are regulated by one or more federal agencies (see
government controls). The regulatory process also provides the added benefit
of uniformly documented use instructions and well-characterized toxicology.
The increased use of non-invasive surgery made
possible by flexible endoscopy and other instruments with sophisticated
optics and computers has placed increased demands on high-level disinfectants
or sterilants. Hospital infection control personnel must be aware of the
capabilities of the formulations used in their infection control programs.
Label information from manufacturers’ and Centers for Disease Control
and Prevention guidelines and publications assist health-care workers
in the selection and proper use of antimicrobial products.
Nursing Homes Protection
As the average lifespan
increases, and baby boomers age, there will be a dramatic increase in
the number of older citizens and nursing home occupancy.
Communal living, coupled
with decreased resistance and general failing health, puts great demands
on sanitation and disinfection practices. Not only may the individuals
have compromised immunity, sanitation challenges frequently occur with
the problem of incontinence. Disinfection of surfaces is essential. To
be effective, a disinfectant must remain in contact with a surface to
be disinfected for the prescribed amount of time. A disinfectant cannot
kill organisms that it does not contact.
While the situation is
not as serious as that in a hospital setting, nursing home caregivers
may not have the same degree of infection control support that is available
in the modern hospital. Health-care providers in these institutions must
be trained in the use of appropriate disinfection of inanimate surfaces
and use of antimicrobial soaps against transmission of disease organisms
through contact with unwashed hands.
