摘要

Background

Understanding the current risk of inpatient mortality following hip fracture in the United States is of significant value to patient families and the health system. Currently, the literature lacks a national representation of the inpatient mortality following hip fracture.

Purpose

The purpose of this study was to investigate the incidence of inpatient mortality following hip fracture using Epic Cosmos—an aggregated, de-identified, multi-institutional data that includes over 280 million patients in the United States.

Methods

A “Cosmos hip fracture cohort” that included all adults (18 years or older) who sustained a femoral neck, intertrochanteric, or subtrochanteric hip fracture (ICD 72.0, S72.1, S72.2) between January 2019 and December 2024 was created. The dataset was queried for demographic data including age, sex, geographic location, incidence of inpatient mortality, and bone health medication use at the time of admission.

Results

The Cosmos database included 284,455,033 patients, of which 1,232,250 hip fracture hospital admissions between January 2019 and December 2024 were identified. Of these patients, 47,773 (3.9%) expired during their hip fracture hospital admission. The most common age bracket was 85 years or older (39.8%), followed by 75–85 (30.0%), and 65–75 (17.8%). Most patients were white (91%) females (55.5%). Most inpatient mortalities occurred in the South (38.4%), followed by the Midwest (31.8%), followed by the Northeast (23.6%), and last by the West (6.2%).

Conclusion

The current inpatient mortality following hip fracture is 3.9%. Most inpatient mortalities occurred in white females above the age of 85 in the South of the country.

Level of Evidence

Level III.
