Abstract

Background: Total joint arthroplasty still causes a lot of blood loss, and many patients require blood transfusions thereafter. Blood transfusions can increase the risk of surgical site infection and periprosthetic joint infection, which can lengthen hospital stays and have a negative impact on patient outcomes.
Objective: This study aimed to examine if relative blood loss and operative time could predict the postoperative increased length of stay following total joint arthroplasty.
Patients and methods: A total of 187 procedures done during 2018–2021 were collected. Any revision case or any patient with hematological disorders was excluded. This led to a cohort of 181 procedures. The following data were collected: age, height, weight, body mass index (BMI), sex, procedure, surgery start time, surgery end time, preoperative hemoglobin and hematocrit levels, postoperative hemoglobin and hematocrit levels, number of packed red blood cells (PRBCs) transfused and the volume of each unit, and the length of stay (LOS).
Results: In our study, age (p < /em> = 0.027, odds ratio = 1.076) and relative blood loss (p < /em> = 0.038, odds ratio = 1.036) were predictors of prolonged LOS. Similarly, there was a significant association between age, operative time (p < /em> < 0.01), and blood loss (p < /em> < 0.001) and LOS.
Conclusion: The operative time, relative blood loss, and age were found to significantly affect the LOS. However, no significant association was found between LOS and gender or BMI.
