Blood transfusion demands in a tertiary otolaryngology, head and neck centre: A 5-year retrospective cohort study.

Objectives: To retrospectively analyse and report the utilisation of red blood cell (RBC) transfusion in a tertiary otolaryngology, head and neck centre in the United Kingdom.

Background: Twenty-seven per cent of RBC transfusions were for surgical indications in a 2014 England and North Wales survey. Currently, there is limited literature on RBC transfusions in Otolaryngology.

Methods/materials: All inpatients admitted primarily under the care of the Otolaryngology, Head and Neck service between January 2015 and December 2019 were analysed. The primary outcomes of interest were number of units of RBC transfused over 5 years and distribution across clinical indications. Secondary outcome measure was cost of RBC transfusions over the same time period.

Results: Most patients receiving transfusions are aged in their sixth and seventh decades. Epistaxis patients utilised 105 RBC units over the 5 years (56% of total RBC units) with emergency epistaxis accounting for 78% of use. Post-operative Head & Neck Cancer surgery with and without reconstruction required 47 RBC units over 5 years (25% of total RBC units). The mean cost incurred by the department over the 5-year period was £6171.49 (SD 1460.25). The cost has fallen by over £2000 over the 5-year period.

Conclusion: Blood transfusion use has fluctuated over the last 5 years. Epistaxis and post-operative Head and Neck cancer cases account for significant use compared with other patient groups. Prehabilitation strategies will add value towards mitigating future consumption of RBC.
