Return to theater in the index episode strongly increased the risk of 30-day return to theater readmission (OR 5.35; 95% CI 4.45-6.43; P<.001), alongside behavioral comorbidities and obesity.

Different predictors for surgical/RTT versus all-cause readmission after THA support distinct metrics; leaves open whether targeting them reduces rates.

Patient-related risk factors for surgical and return-to-theater readmissions after THA differ from those for all-cause readmission, highlighting the need for specific metrics in risk reduction strategies.
Ali et al. (2017) conducted a cohort in Primary total hip arthroplasty (n=514,455). Return to theater in the index episode and patient comorbidities vs. Patients without these risk factors was evaluated on 30-day readmission resulting in return to theater (RTT) (OR 5.35, 95% CI 4.45-6.43, p=<.001). Return to theater in the index episode strongly increased the risk of 30-day return to theater readmission (OR 5.35; 95% CI 4.45-6.43; P<.001), alongside behavioral comorbidities and obesity.
