Abstract
Purpose
Describe the experience of one institution in modifying allogeneic blood transfusion protocols for AIS surgery in response to the results of ACS-NSQIP-PEDS comparative data in a retrospective cohort study.
Methods
NSQIP data demonstrated that AIS patients at our hospital had a significantly greater risk of ALBT compared to similar institutions (OR 4.1). The ALBT protocol was then revised to initiate transfusion based on Hb/Hct level, clinical hypotension and/or discussion between surgeon and anesthesiologist. A retrospective analysis of perioperative ALBT and autologous cell salvage blood transfusion (CSBT) rates was performed for patients undergoing surgery before (Group A) and after (Group B) the implementation of the revised protocol.
Results
Two hundred and ninety patients constituted the study cohort, with 92 patients in Group A and 198 in Group B. Average total blood transfusion (ALBT + CSBT) per patient was significantly lower for Group B than Group A (313 ml vs. 650 ml, p < 0.01). ALBT per patient of Group B was significantly lower than Group A (85 ml vs. 324 ml, p < 0.01). 48% of patients received ALBT in Group A compared to only 18% in Group B.
Conclusion
Recognition of excessive allogeneic transfusion rates in our institution through comparative data from the ACS-NSQIP-PEDS database resulted in the modification of transfusion parameters that led to a decrease in allogeneic transfusion rates for AIS patients. The current study highlights the value of a large, well-curated surgical database in optimizing clinical protocols and potentially improving overall surgical morbidity.
