From: Decolonization of patients and health care workers to control nosocomial spread of methicillin-resistant Staphylococcus aureus:a simulation study

Figure 2

The effects of health care worker decolonization on the patient prevalence level of MRSA. Scenarios I and II, correspond to the relative importance of persistently colonized health care workers (HCW) in the spread of MRSA (being 50% and 10 %, respectively) in the endemic situation. Scenarios A and B correspond to different values for the percentage of persistently colonized HCWs. Results are based on 50 runs of the stochastic simulation model. The lines represent the average hospital-wide MRSA patient prevalence, starting from the baseline scenario of an average patient prevalence of 14% (high endemicity level). The red line represents the patient prevalence with patient decolonization (100% efficacious ) and the other lines represent the patient prevalence with health care worker decolonization (100% efficacious) performed once per year (blue), twice per year (purple) and every month (yellow).
