Relation of tranexamic acid therapy to length of stay in the hip fracture population

Abstract

Tranexamic acid (TXA) is a medication that is routinely used to minimize blood loss during surgery. There is minimal literature evaluating the effects of TXA in hip fractures in regards to length of stay, readmission rates, and location of discharge. This study included adult patients who were admitted for hip fracture that required surgery over a 22-month period (May 2017–February 2019). A total of 525 hip fractures were operated on during this time period. Retrospective analysis was performed on patients treated with TXA (n = 27) vs those who were not (n = 498). Primary outcomes were length of stay, disposition after discharge, need for transfusion, mobilization with therapy, and readmission rates. TXA during hip fractures reduced median length of stay in the hip fracture cohort to 3 vs 5 days (P < 0.01). Patients were more likely to be discharged home as opposed to a nursing facility. Patients who received TXA during their hip fracture surgery were less likely to need transfusions while admitted (P < 0.01). No increased readmission rates were seen within 30 days after discharge (P = 0.59). In conclusion, when indicated, TXA appears to be safe for utilization in hip fracture surgery, resulting in decreased length of stay, less transfusions, and no increase in readmission rates.
