Age Alone Does Not Predict Complications, Length of Stay, and Cost for Patients Older Than 90 Years With Hip Fractures.

Abstract

The purpose of this study was to analyze the perioperative complication rate and inpatient hospitalization costs associated with hip fractures in patients older than 90 years compared with patients younger than 90 years. Patients 60 years and older with hip fractures treated operatively at 1 academic medical center between October 2014 and September 2016 were analyzed. Patient demographics, comorbidities, length of stay, procedure performed, and inpatient complications were analyzed. Total cost of admission was obtained from the hospital finance department. Outcomes were compared between patients older than 90 years and patients younger than 90 years. A total of 500 patients with hip fractures were included in this study. There were 109 (21.8%) patients 90 years and older and 391 (78.2%) patients 60 to 89 years. There was no difference in fracture pattern, operation performed, Charlson Comorbidity Index, or length of stay between the 2 groups. The mean length of stay for patients 90 years and older with hip fractures was 7.8±4.3 days vs 7.6±4.2 days for the younger cohort (P=.552). There was no observed difference in perioperative complications. Finally, there was no difference in the total mean cost of admission. Patients 90 years and older are at no greater risk for perioperative complications based on age alone. They are also no more likely to require longer or more costly hospitalizations than patients younger than 90 years. [Orthopedics. 2019; 42(1):e51-e55.].
