Factors affecting length of stay after isolated femoral shaft fractures.

BACKGROUND

Controlling escalating health care costs is important for hospitals and has far reaching implications for society. Hospital length of stay (LOS) is one of the most reliable predictors of cost after trauma. Our purpose was to establish LOS after isolated femur fractures treated by intramedullary (IM) nail.

METHODS

The trauma registry was queried to identify patients. Patients were excluded if they required assistive ambulatory devices before injury, had chronic/terminal illness or compromised brain function. There were 102 patients with an average age of 27 years. Statistical analysis was completed.

RESULTS

The average LOS was 3.9 days. In all, 27 patients stayed longer than 4 days. Reasons included social (7), medical (10), and hospital delays (10). The average time from arrival to surgery was 17 hours. The average time from surgery to physical therapy was 1.3 days. Patients who had surgery more than 24 hours after arrival stayed longer. Patients requiring placement stayed 2.4 days longer until placement was found.

CONCLUSIONS

Factors the hospital can control to reduce LOS include time to surgery, time for physical therapy evaluation, and radiology delays (for spine clearance radiographs). Physical therapy availability within 24 hours of surgery is important and should include weekends and holidays. Early evaluation of social factors including homelessness or obstacles to independent living may reduce time to find placement. LOS reduction after femur fractures will decrease the cost of trauma to the hospital. In addition, LOS reduction will possibly increase bed availability and minimize the time spent on diversion yielding greater revenues and increasing patient satisfaction.
