T19 struggled to maintain sterility while setting up the arm carts.C19 repeatedly walked between the non- sterile table and the bedside to communicate the tilt and dock angles to S19.S19 said it was strange for her to have a guide that C19 had to hold up while she performed the procedure.S19 would want the guide to be posted on the wall or to have her own sterile copy, or otherwise she would write the necessary information on the drapes.Study artifact: setup guide format – The study materials included a non- sterile setup guide printed on 8.5” x 11” paper, though the setup guide would be available to users electronically, thereby enabling them to print it and post it on the wall (T19).
