Abstract

Implantation of medical devices is becoming more prevalent, and as a result, a greater number of patients who fall accidentally are expected to have a medical implant. The Nationwide Inpatient Sample (NIS) was used to evaluate hospital admissions following accidental falls involving re-operation of existing medical implants (hip, knee, spine, and fracture fixation) from 1990 to 2005. From 1990 to 2005, hospitalisations due to accidental falls on level surfaces increased by 306%, and hospitalisations due to falls from stairs increased by 310%. Falls involving orthopaedic revision surgery (re-operation) are relatively rare, but the incidence has increased by approximately 35%. Hospital stays after falls on level surfaces involving re-operation were 1.0 day (median) longer and cost 50% (median) more than those that did not involve re-operation in 2005. After staircase falls, hospital stays for patients undergoing re-operations were 2.0 days (median) longer and cost 108% (median) more. The greater hospital costs and hospital stay for patients needing re-operations indicate that additional medical treatment was required.
