More hospital nurses = fewer patient infections?

The more nurses there are in each hospital, the fewer patient infections will occur, according to a new piece of research. The sheer amount of infection-reducing procedures used by nurses to prevent infections makes this research's conclusion pretty easy to agree with.

Infections caused by ventilator-associated pneumonia (VAP) are serious and are easily caused by bacteria entering the patients lung when a ventilator is used. The more a nurse can attend to the specific needs of each individual patient, the less of an occurrence of these situations is a result.

Do hospitals measure the types of patient needs (statistically speaking) against the budgetary constraints of nursing staff along with many other variables to find the best mix of efficiency and top-flight patient care? I'd hope so, and any good hospital administration professional should also.
