With the current obesity epidemic in the United States, nurses and others who are routinely required to move patients may be at risk for injury in the normal course of their duties. In the past the practice was to collect six nurses who were the strongest on that floor and let them all work together to move an obese patient. Recently however, hospitals have brought in new ways of moving patients, such as ceiling lifts and different types of slings. These reduce the amount of weight a nurse actually has to lift at one time, and also help move the patient safely so that individual isn't harmed during the process. The goal is to reduce everyone's risk as much as possible.
