 A hip fracture adjudication committee, blinded to the side of the fracture, will review all information including hospital records and radiologists reports or hip radiographs and issue a decision on whether a fracture has occurred. Primary analyses will be performed using an intention to treat approach. Secondary analyses will investigate resident and nursing home factors associated with hip protection compliance and effectiveness. An independent Data and Safety Monitoring Board DSMB has been convened and will review hip fracture rates and adverse event data at regular intervals.
