Project CLEAR trial summary: Huang et al. randomized 2,141 patients colonized with MRSA to hygiene education or hygiene education + decontamination. Decolonization involved chlorhexidine mouthwash, baths or showers with chlorhexidine, and nasal mupirocin for 5 days twice per month for 6 months. The primary objective was to assess the efficacy of postdischarge hygiene education, as compared with education plus decolonization, in patients colonized with MRSA (carriers). The results showed a significant decrease in MRSA infections in the decontamination group (P=0.03, NNT=30). The authors of the Project CLEAR trial concluded that postdischarge MRSA decolonization with chlorhexidine and mupirocin led to a 30% lower risk of MRSA infection than education alone.
