The client was a double amputee and required the use of a wheelchair for mobility. He called a local ambulance company for assistance so that he could be carried into his house. Instead of using a proper stair carrier to get him into his house, ambulance personnel attempted to carry the client in his own wheelchair up the front stairs. The ambulance personnel lost control of the wheelchair and dropped him down the stairs. The client hit his head and suffered brief loss of consciousness and also sustained a collarbone injury.
