Feasibility of Hip Fracture Surgery Using a No Transfusion Protocol in Elderly Patients: A Propensity Score-Matched Cohort Study.

OBJECTIVES: To determine whether hip fracture surgery (HFS) without transfusion affects postoperative mortality and complications in elderly patients.

DESIGN: Retrospective comparative study.

PATIENTS: Three hundred fourteen patients ≥65 years of age who underwent HFS between May 2003 and December 2014. Patients were divided into 2 groups: those who consented to blood transfusion if needed and those who did not. One-to-one propensity score matching generated 50 matched pairs of patients.

INTERVENTION: Patients underwent HFS with or without blood transfusion. In the no transfusion group, simultaneous administration of erythropoietin and iron was used as an alternative.

MAIN OUTCOME MEASUREMENTS: The primary outcome was postoperative mortality (90-day, 1-year, overall). The secondary outcomes were hemoglobin change and the incidence of postoperative complications.

RESULTS: HFS using a no transfusion protocol was not associated with increased mortality at any time point. Mean hemoglobin levels were significantly different between the 2 groups on postoperative day 1 (11.0 ± 1.3 vs. 10.5 ± 1.6, P = 0.002) but levels completely recovered within 2 weeks in both groups. There was also no difference in postoperative complication rates between the 2 groups, and overall hospital stays and charges were similar.

CONCLUSIONS: An HFS protocol without blood transfusion was not associated with increased mortality or complications in elderly patients.

LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
