Shaw JH, Wesemann LD, Ayoola AS, et al. - Experts aspired to explore whether socioeconomic (SE) parameters, primarily area deprivation index (ADI), relate to postoperative emergency department (ED) visits after total knee arthroplasty (TKA). They retrospectively reviewed 2,655 patients who had TKA in a health system of 4 hospitals. Four hundred thirty-six patients (16.4%) presented to the ED within 90 days. The study found that ADI was not a predictor of 90-day postoperative ED visits and that the percentage of early ED returns after TKA was high. The only SE factor that could have contributed to this phenomenon was the type of insurance. Once in the ED, race, preoperative ED visits, preoperative anticoagulation, BMI, gender, and preoperative American Society of Anesthesiologists score all increased the risk of readmission. The study contributes to hospitals' mission of providing equal access to healthcare.
