Background:
Acetabular fractures are highly complex injuries often resulting from high-energy trauma that orthopedic surgeons commonly address and treat. The use of open reduction internal fixation (ORIF) has increased in recent years and is highly technical, in that the quality of ORIF directly affects patient outcome. Studies have characterized multiple factors that contribute to post- operative quality of life. The purpose of this study is to further this understanding and investigate how (1) patient demographics and (2) patient-specific risk factors affect 90-day readmissions in patients.
Methods:
A retrospective, nationwide query of private insurance database from January 1st, 2010 to October 31st, 2020 was performed using ICD-9, ICD-10, and CPT codes. Patients who underwent acetabular fracture ORIF for acetabular fractures and were readmitted within 90 days following index procedure were included, while those patients who were not readmitted served as comparison controls, yielding a total of 3942 patients. Patients were divided by demographics (age and sex) and specific risk factors associated with readmission. A logistic regression model was used to identify the odds ratio (OR) and 95% confidence interval. Alpha-value of less than 0.002 was considered statistically significant.
Results:
The query yielded a total of 3,942 patients. Age and sex were found to be non-significant contributing risk factors to 90-day readmissions (p = 0.251 and p = 0.531, respectively). Data also showed that statistically significant co-morbidities included arrhythmia (OR:1.32, 1.16-1.78, p< 0.0001), cerebrovascular disease (OR: 1.43, OR: 1.43, CI: 1.16-1.78, p< 0.0001), coagulopathy (OR: 1.62, 1.30-2.02, p < 0.0001), fluid and electrolyte abnormalities (OR: 1.52, CI: 1.25-1.84, p< 0.0001), and pathologic weight loss (OR: 1.37, CI: 1.10-1.70, p< 0.0001). 
Conclusion:
This study illustrated how several patient-specific risk factors may contribute to increased 90-day readmission risk following acetabular ORIF. A heightened awareness of these comorbidities in patients requiring acetabular ORIF is required to improve patient outcomes and minimize rates of readmission. Further investigation is needed to optimize quality of ORIF in these patient populations, improve patient outcomes, and increase awareness of potential postoperative complications in these higher-risk patient populations.
