title: Role of Sociodemographic, Co-morbid and Intraoperative Factors in Length of Stay Following Primary Total Hip Arthroplasty.
abstract: We aimed to examine and quantify the combined association of patient sociodemographic, preoperative comorbidities and intraoperative factors with extended and prolonged length of stay (LOS) following primary total hip arthroplasty. Longer LOS was associated with Age (≥65 years), BMI ≥30 kg/m(2), ASA score >2, minority race/ethnicity, low SES, general anesthesia, comorbidities of the Circulatory, Genitourinary and Respiratory systems, and operating time. Collectively, being of low SES, advanced age (≥65 years) and minority race/ethnicity was most significantly associated with prolonged LOS (>7 days). The combined associations of lower SES, female gender, advanced age, non-Caucasian race/ethnicity and certain comorbidities presented a synergistically elevated risk for longer LOS and may warrant the need to consider sociodemographic status when allocating resources to hospitals serving such patients.
