Importance: Surgery within 24 hours after a hip fracture improves patient morbidity and mortality, which has led some hospitals to launch quality improvement programs (eg, targeted resource management, documented protocols) to address delays. However, these programs have had mixed results in terms of decreased time to surgery (TTS), identifying an opportunity to improve the effectiveness of interventions., Objective: To identify the contextual determinants (site-specific barriers and facilitators) of TTS for patients with hip fracture across diverse hospitals., Design, Setting, and Participants: This qualitative mixed-methods study used an exploratory sequential design that comprised 2 phases. In phase 1, qualitative semistructured interviews were conducted with stakeholders involved in hip fracture care (orthopedic surgeons or residents, emergency medicine physicians, hospitalists, anesthesiologists, nurses, and clinical or support staff) at 4 hospitals with differing financial, operational, and educational structures. Interviews were completed between May and July 2021. In phase 2, a quantitative survey assessing contextual determinants of TTS within 24 hours for adult patients with hip fracture was completed by orthopedic surgeon leaders representing 23 diverse hospitals across the US between May and July 2022. Data analysis was performed in August 2022., Main Outcomes and Measures: Thematic analysis of the interviews identified themes of contextual determinants of TTS within 24 hours for patients with hip fracture. The emergent contextual determinants were then measured across multiple hospitals, and frequency and distribution were used to assess associations between determinants and various hospital characteristics (eg, setting, number of beds)., Results: A total of 34 stakeholders were interviewed in phase 1, and 23 surveys were completed in phase 2. More than half of respondents in both phases were men (19 [56%] and 18 [78%], respectively). The following 4 themes of contextual determinants of TTS within 24 hours were identified: availability, care coordination, improvement climate, and incentive structure. Within these themes, the most commonly identified determinants across the various hospitals involved operating room availability, a formal comanagement system between orthopedics and medicine or geriatrics, the presence of a physician champion focused on timely surgery, and a program that facilitates improvement work., Conclusions and Relevance: In this study, contextual determinants of TTS within 24 hours for patients with hip fracture varied across hospital sites and could not be generalized across various hospital contexts because no 2 sites had identical profiles. As such, these findings suggest that guidance on strategies for improving TTS should be based on the contextual determinants unique to each hospital.

Purpose: Tranexamic acid (TXA) reduces need for transfusion in total joint arthroplasty, though findings in acetabular surgery are conflicting. We compared outcomes after acetabular fracture surgery with or without perioperative intravenous (IV) TXA administration., Methods: We performed a retrospective review of 305 patients with acetabular fractures that underwent open reduction and internal fixation (ORIF). Eighty-nine patients received TXA, and 216 did not. The primary outcome was rates of intraoperative and postoperative allogeneic blood transfusion., Results: Baseline demographics and characteristics were similar. Time from injury to surgery and estimated blood loss were comparable. Operative time (p < 0.01) and intraoperative IV fluids (p < 0.01) were greater in the non-TXA group. The proportion of patients who received blood transfusion and mean units transfused intraoperatively and postoperatively did not differ. Mean differences in preoperative and postoperative hemoglobin and hematocrit, hospital length of stay, and perioperative complications also did not differ. In a multivariable regression model, age 60-70 years, Charlson Comorbidity Index, Injury Severity Score, and fracture patterns likely to bleed were independently associated with intraoperative transfusion. Anterior surgical approaches and intraoperative transfusion requirement were independently associated with postoperative transfusion., Conclusion: In this study, perioperative IV TXA did not decrease blood loss, need for transfusion, or improve in-hospital outcomes of acetabular fracture surgery. Age 60-70, CCI, ISS, and fracture patterns likely to bleed were independently associated with intraoperative transfusion. Anterior surgical approach and need for intraoperative transfusion were independently associated with postoperative transfusion. Further prospective trials are warranted to confirm these findings., (© 2021. The Author(s), under exclusive licence to Springer-Verlag France SAS, part of Springer Nature.)
