Medical Comorbidity and Male Sex Are Associated With Higher In-hospital Mortality for 90-Day Readmissions and Higher Readmission Rates After Nonelective Primary Total Hip Arthroplasty for Hip Fracture

In contemporary U.S. national data from 2016 to 2019, medical comorbidity and male sex were each associated with a higher risk of 90-day readmission and in-hospital mortality following primary nonelective THA for hip fracture. Further investigation into mechanisms and pathways of increased risk in men and those with higher medical comorbidity undergoing primary THA for hip fracture is needed, which can lead to the development of pathways for risk reduction and improved outcomes.
