OR workers have to mentally multitask when sharps are in use, focusing simultaneously on patient and worker safety. The human tendency is to devise a pecking order, and most often, patient safety comes first. Even if there is unexpected bleeding during a procedure, and speed becomes a factor, patient safety is still at the fore, right? This is by no means wrong - it's just that you must give worker safety nearly as much attention.
Taking steps to reduce patient falls is always prudent. It might also be timely, as one of JCAHO's 2005 National Patient Safety Goals calls for facilities to "assess and periodically reassess each patient's risk for falling."
