Preoperative Chronic Opioid Use and Its Effects on Total Knee Arthroplasty Outcomes

J Knee Surg DOI: 10.1055/s-0039-1678538Unsafe opioid distribution remains a major concern among the total knee arthroplasty (TKA) population. Perioperative opioid use has been shown to be associated with poorer outcomes in patients undergoing TKA including longer length of stay (LOS) and discharges to extended care facilities. The current study aims to detail perioperative opioid use patterns and investigate the effects of preoperative chronic opioid use on perioperative quality outcomes in TKA patients. A retrospective analysis was performed on 338 consecutive TKAs conducted at our institution. Two cohorts were compared in this study—preoperative chronic opioid users and nonchronic opioid users. Opioid usage patterns and quality metrics were collected and analyzed over a 3-month preoperative and a 6-month postoperative period. Fifty-four (16.0%) preoperative chronic opioid users were identified out of the total 338 patients included in the study. Preoperative chronic opioid users experienced significantly longer LOS (2.9 vs 2.6 days; p = 0.026). Patients who remained persistent chronic users throughout the preoperative and postoperative stages demonstrated a significantly longer LOS (3.4 days vs 2.5 days; p = 0.017) compared with those who were no longer chronically using opioids by the 6 months postoperative period. By the 6 months postoperative time point, preoperative chronic users were consuming eight times the morphine-equivalents (mg/d...

We investigated the development of three different types of contextual control recruitment in children (9- and 12-year-olds) and young adults. First, we implemented a list-wide proportion congruence manipulation in which conflict trials were frequently/infrequently presented within a list of trials. S...

ConclusionsFindings suggest that self-harm behavior and psychiatric disorders are associated with increased ED utilization for subsequent chronic disease-related ED utilization. Chronic disease among adolescent psychiatric patients should be attended to, potentially involving new models of clinical follow-up care.

Comparing findings from four different regions, we scrutinize whether and how educational institutions empower Ugandan youth to participate in society as active, informed, critical and responsible citizens. Theoretically, we focus on four different aspects of individual political agency that education can foster, namely: understanding of...

KerryAbstractThe study objectives were to determine assessors' (n = 256) preference for corned beef, produced with sequential reductions in NaCl concentrations and to determine if preference was affected by assessor age. The use of a salt replacer such as potassium lactate was also assessed. The youngest age cohort disliked samples containing the highest level of NaCl, whereas the oldest age cohort did not detect differences between samples. The most negatively perceived sampl...

Conclusion: Acute TBI may suppress E2 and increase CORT in young women. OCs appeared to independently affect CORT and FSH responses. Future work is needed with a larger sample to characterize TBI effects on women's endogenous hormone response to injury and OC use's effects on post-TBI stress response and gonadal function, as well as secondary injury.
