Figure 6. Impact of infection control measures on the prevalence of CPKP colonization in an hyperendemic setting.

Figure 6

Infection control measures start on day 0 where a high colonization prevalence of 21% was assumed. The evaluated scenarios include: 1. Hand hygiene compliance p = 60%, 2. p = 80%, 3. p = 60% and reduce colonization prevalence on admission of CPKP by 60% (through active surveillance and subsequent isolation or strict contact precautions for positive patients), 4. p = 60% and reduce colonization prevalence on admission of CPKP by 90%, 5. p = 80% and reduce colonization prevalence on admission of CPKP by 90%. Dashed lines (- - -) correspond to the above scenarios with the addition of 50% reduction in the duration of antibiotic usage during patients' stay in the unit (assuming a relative risk associated with antibiotic use equal to 3).
