[Comment] The case for stepped-wedge studies: a trial of falls prevention
To do no harm is a fundamental tenet of clinical practice. Falls are harmful, especially for elderly people, because they can result in loss of confidence and permanent restriction of mobility. This is particularly the case in hospital settings, where hard flooring, sharp-edged furniture, and moveable bed furniture all increase the potential for serious injury. Patients are, by being in hospital, in a state of vulnerability. Disorientation, delirium, and weakness can increase the risk of falls.
