What is the relationship between nosocomial infections and mortality and healthcare cost?  

Nosocomial infections, or hospital acquired infections, are a major cause of mortality and healthcare cost that affect millions of patients each year. These are illnesses contracted while in the hospital setting due to contact with contaminated surfaces and/or equipment, inadequate hand hygiene among staff members, and other factors which can then lead to serious complications such as sepsis or death.

In terms of overall costs associated with this problem it is estimated that nosocomial infections add an additional $9.8 billion dollars annually to US healthcare expenditures – not only resulting in longer lengths of stay but also increased utilization resources as well (e.g., antibiotics used for treatment).

Moreover, studies have shown that these types of infections often result in greater mortality rates too – particularly among those suffering from conditions such as cancer or severe respiratory issues where weakened immune systems make them more vulnerable contracting these illnesses.

Overall then, it is clear to see the devastating impact nosocomial infections have both patients their families alike so it vital that proper protocols be put place ensure optimal prevention efforts taken whenever possible.
