Resistant infection is a serious nosocomial problem. There are few antibiotics that are effective in
treating these infections, and the patient consequences can be significant, including amputation and death.
Moreover, these infections add significantly to the cost of patient care and add to the patient length of
stay. Medicare has just recently announced that they will no longer reimburse healthcare providers for
the added cost of nosocomial infection, meaning that the provider will have to shoulder the complete
cost of treating the infection.(Pear, 2007) One of the most difficult of the resistant infections is MRSA
(Methicillin Resistant Staph), and we will use the term, MRSA, to represent the general category of
resistant infections.
In the past, focus has been on general infection control procedures (Coia et al., 2006; Henderson,
2006), assuming a uniform patient risk, or on targeting patients using specific demographic and health
parameters.(Roghmann, 2000; Lodise, McKinnon, & Rybak, 2003) In these studies, one patient location
(for example, ICU)(Gerber et al., 2006; McBryde, Pettit, & McElwain, 2007) or one patient treatment
