Short-term postoperative mortality events in patients over 80 years of age with hip fracture: analysis at a single institution with limited medical resources.
BACKGROUND
Lethal events represent the most important complication in the treatment of hip fracture in elderly patients. Despite the increasing chance for treatment of such conditions, few data regarding risk factors associated with lethal events have been determined for ordinary hospitals with limited medical and human resources, particularly in Japan.


METHODS
The incidence of postoperative lethal events and related preoperative risk factors in extremely elderly patients (>80 years) with hip fracture were retrospectively analyzed in our hospital for the past 2 years.


RESULTS
Lethal events occurred in 11 (10.7%) of 103 patients within 3 months postoperatively. In both univariate and multivariate analyses, an elevated number of co-morbidities and preoperative respiratory dysfunction were identified as significant risk factors. Delay in surgery was not a risk factor for lethal events.


CONCLUSIONS
A valid reason for delay is the need to stabilize concurrent medical conditions due to multiple co-morbidities in extremely elderly patients with hip fracture. Considering the limited resources and extreme age of the subjects, the mortality rate in the present study was quite acceptable. Patients, families of patients, and physicians should recognize the increased risk of mortality for patients with significant risk factors in the surgical treatment of hip fracture.
