Frequency and Treatment Trends for Periprosthetic Fractures About Total Hip Arthroplasty in the United States

Abstract

BackgroundPeriprosthetic hip fractures (PPHFx) are challenging complications that have become increasingly more prevalent. Wide variability exists in the quality and size of prior studies pertaining to hospital stay information. This study used the largest publicly available database in the United States to evaluate perioperative hospital data of PPHFx. MethodsThe Healthcare Cost and Utilization Project–Nationwide Inpatient Sample was used to analyze trends related to the frequency, fracture type, mortality, treatment, patient demographics, time to surgery, length of stay (LOS), and hospital charges associated with PPHFx from 2006-2010. ResultsFrom 2006-2010, average patient age (76.7 years), hospital characteristics, rate of PPHFx, treatment choice, LOS (8.03 days), mortality (2.6%), disposition (78.1% to skilled nursing facility or inpatient rehab), and time to procedure (1.98 days) all remained relatively stable. The southern United States had the highest frequency of PPHFx and females had nearly twice the rate of PPHFx each year at an average of 67%. Despite these consistencies, hospital charges increased by an average of 8.3% per year over the study period ($27,683 over 5 years, P < .0001). ConclusionIn the era of containing cost while improving quality of care, this study demonstrates that despite consistent treatment trends of PPHFx, hospital charges are increasing independently. Regardless, surgeons can work to reduce LOS and charge to post acute care facilities to lessen spending. Refining our understanding of these relationships will be fundamental to further improving quality of care and cutting cost associated with these fractures.
