Hand hygiene continues to play a critical role in protecting patients from the threats of infection. It is one of the most important ways to prevent the spread of germs both inside a healthcare facility and outside in homes, schools, and the community.

A commonplace greeting in my cultures, the handshake, has the potential to directly transmit germs between individuals. Alternative greetings continue to be explored to minimize the risks involved. In a recent AJIC study, Whitworth and Mela performed trials to determine if alternative greetings, such as the fist bump and high-five, would transmit fewer germs than the traditional handshake.

A greeting donor immersed a sterile-gloved hand into a container of germs and proceeded to exchange a series of greetings with a sterile-gloved recipient. Exchanges randomly varied in duration and intensity of contact. The handshake resulted in a transfer of nearly twice the bacteria (mean 1.24 x 108 CFU) of a high-five, whereas the fist bump consistently experienced the lowest transmission.1

Furthermore, they identified a direct correlation between surface area of contact, strength of grip, and duration of contact to the amount of bacteria transferred. These studies open the door for additional dialogue around the use of limited or non-contact greetings such as the head nod, wave, bow, and fist bump.

Implementing these non-contact greetings, however, would prompt a culture change. Social and professional contexts place great value in the handshake and its quality.2,3 Healthcare professionals are often encouraged to engage in handshakes with patients to establish rapport and meet their expectations.1

Handshakes are unlikely to vanish anytime soon, but making a conscious effort to reduce or eliminate unnecessary hand contact may help further protect the health and safety of patients. No-contact greetings seem ideal, but wide acceptance could prove challenging. The fist bump or other so-called dap greetings seem to be a compelling alternative for consideration. These studies will continue to enable more productive dialogue around this issue and may contribute to policies that further promote hand hygiene and patient safety.

Which form of greeting makes the most sense for the healthcare community?
