Analysis of the incidence and risk factors of blood transfusion in robot-assisted laparoscopic total hysterectomy: a retrospective nationwide inpatient sample database study

In conclusion, this study reports a 3.47% incidence of transfusion in RA-TLH and identifies high-risk patient profiles based on race, insurance status, and specific comorbidities. Furthermore, transfusion was independently associated with significantly poorer outcomes, including longer LOS, increased inpatient charges, and higher hospital mortality. These findings provide critical data for preoperative optimization, enhancing risk stratification, patient counseling, and the development of targeted blood management strategies to prevent adverse events.
