Background: Alcohol use disorder (AUD) is the most prevalent substance use disorder in the United States. However, the current literature on AUD as a preoperative risk factor for Total Shoulder Arthroplasty (TSA) outcomes is limited. The purpose of this study was to identify the association of AUD with revision rates and 90-day postoperative complications in TSA., Methods: A retrospective study was conducted using the PearlDiver database. Patients diagnosed with AUD were identified. Patients in remission or with underlying cirrhosis were excluded. Outcomes included 2-year revision, 90-day readmission, 90-day emergency, and 90-day post-operative medical complications. Analysis was performed with univariate chi-squared tests followed by multivariable logistic regression., Results: A total of 59,261 patients who underwent TSA for osteoarthritis were identified, with 1522 patients having a diagnosis of AUD. Multivariable logistic regression showed that patients with AUD were more likely to undergo 2-year all-cause revision (OR = 1.49, p   =  0.007), 2-year aseptic revision (OR = 1.47, p   =  0.014), 90-day hospital readmission (OR = 1.57, p   =  0.015), and 90-day transient mental disorder (OR = 2.13, p   =  0.026)., Conclusions: AUD is associated with increased rates of 2-year revision surgery, as well as 90-day readmission and 90-day transient mental disorder following primary TSA for osteoarthritis. These findings may assist orthopedic surgeons in counseling patients with AUD during the pre-operative course., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Introduction: Understanding the trends among patients undergoing same-day discharge (SDD) total hip arthroplasty (THA) is imperative to highlight the progression of outpatient surgery and the criteria used for enrollment. The purpose of this study was to identify trends in demographic characteristics and outcomes among patients who participated in an academic hospital SDD THA program over 6 years., Methods: We retrospectively reviewed all patients who enrolled in our institution's SDD THA program from January 2015 to October 2020. Patient demographics, failure-to-launch rate, as well as readmission and revision rates were evaluated. Trends for continuous variables were analyzed using analysis of variance, and categorical variables were analyzed using chi-square tests., Results: In total, 1,334 patients participated in our SDD THA program between 2015 and 2020. Age (54.82 to 57.94 years; P < 0.001) and mean Charlson Comorbidity Index (2.15 to 2.90; P < 0.001) significantly differed over the 6-year period. More African Americans (4.3 to 12.3%; P = 0.003) and American Society of Anesthesiology class III (3.2% to 5.8%; P < 0.001) patients enrolled in the program over time. Sex ( P = 0.069), BMI ( P = 0.081), marital status ( P = 0.069), and smoking status ( P = 0.186) did not statistically differ. Although the failure-to-launch rate (0.0% to 12.0%; P < 0.001) increased over time, the 90-day readmissions ( P = 0.204) and 90-day revisions ( P = 0.110) did not statistically differ., Conclusion: More African Americans, older aged individuals, and patients with higher preexisting comorbidity burden enrolled in the program over this period. Our findings are a reflection of a more inclusive selection criterion for participation in the SDD THA program. These results highlight the potential increase in the number of patients and surgeons interested in SDD THA, which is paramount in the current incentivized and value-based healthcare environment., Level Evidence: III, Retrospective Review., (Copyright © 2024 by the American Academy of Orthopaedic Surgeons.)

Introduction: As the utilization of total shoulder arthroplasty (TSA) increases, it is essential to identify risk factors associated with postoperative complications. Urinary tract infection (UTI) is one such example. Our objective is to identify whether UTI is associated with increased rates of prosthetic joint infection (PJI) and determine whether its treatment reduces PJI rates., Methods: Patients who underwent primary TSA for glenohumeral osteoarthritis between 2010 and 2019 with minimum two-year follow-up were identified in a national database (PearlDiver Technologies) using Current Procedural Terminology and International Classification of Diseases codes. These patients were stratified into two cohorts: those with preoperative UTI within two weeks of TSA and those without. The preoperative UTI cohort was stratified into those treated and those untreated prior to TSA. Univariate and multivariable analyses were performed., Results: Following multivariable analysis, there were significantly higher odds of postoperative anemia, pulmonary embolism, and death in the UTI cohort. Comparing treated to untreated UTI, there were no significant differences in multivariable analysis for any 90-day medical or two-year surgical complications., Discussion: This study showed that UTI was not associated with increased rates of PJI. UTI was, however, associated with postoperative medical complications that surgeons should be aware of., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)
