Well-powered studies analyzing the relationship and nature of emergency department (ED) visits following primary total hip arthroplasties (THAs) are limited. 

The aim of this study was to: 1) compare baseline demographics of patients with/without an ED visit; 2) determine leading causes of ED visits; 3) identify patient-related risk factors; and 4) quantify 90-day episode-of-care healthcare costs divided by final diagnosis.

Patients undergoing primary THA between January 1, 2010 and October 1, 2020 who presented to the ED within 90-days post-operatively were identified using the Mariner dataset of PearlDiver, yielding 1,018,772 patients.

This included 3.9% (n=39,439) patients who did and 96.1% (n=979,333) who did not have an ED visit. Baseline demographics between the control/study cohorts, ED visit causes, risk-factors, and subsequent costs-of-care were analyzed. Using Bonferroni-correction, a p-value less than 0.002 was considered statistically significant.
