Abstract Background Pre-operative anemia is a common, but treatable, condition encountered by surgical patients. It has been associated with increased perioperative complications, length of stay, and blood transfusions. The aim of this project was to increase the treatment rate of pre-operative anemia to 75% of patients consented for major hepato-pancreato-biliary (HPB) surgery. Methods This was an interrupted time series study and a spread initiative from a similar project in a colorectal surgery population. Interventions included an anemia screening and treatment algorithm, standardized blood work, referral to a patient blood management program, and standardized oral iron prescriptions. The primary outcome measure was the change in pre-operative anemia treatment rate and the secondary outcome measure was the post treatment increase in hemoglobin. Results A total of 208 patients were included (n = 124 pre-intervention and n = 84 post-intervention). Anemia was present in 39.9% of patients. The treatment rate of pre-operative anemia increased to 44.1% from 28.6%. The mean hemoglobin increased from 110 g/L to 119 g/L in patients who were treated (p = 0.03). There was no significant increase or decrease in blood transfusions or mean number of red cell units transfused per patient. Screening rates for pre-operative anemia increased from 41.1 to 64.3% and appropriate referrals to the patient blood management program increased from 14.3 to 67.6%. Conclusions This study demonstrates a small scale spread initiative focused on the treatment of pre-operative anemia. Although the goal to treat 75% of anemic patients was not reached, an effective referral pathway to an existing patient blood management program was developed, and a significant increase in the mean hemoglobin in anemic patients who have been treated pre-operatively was demonstrated.
