Transfer of methicillin-resistant Staphylococcus aureus by fist bump versus elbow bump.

For 40 patients with methicillin-resistant (MRSA) colonization, fist bump and elbow bump greetings resulted in frequent transfer of MRSA (25% vs 15%, respectively), but significantly fewer colonies were transferred via the elbow bump. Noncontact greetings should be encouraged to reduce the risk of transfer of healthcare-associated pathogens.
