Abstract Introduction The Cord Support Programme (CSP) has been run for UK Transplant Centres (TCs) by Anthony Nolan (AN) and NHS Blood and Transplant (NHSBT) for 5 years. CSP supports TCs in Cord Blood Unit (CBU) selection and quality assessment as well as providing training and on-site assistance. To maintain and grow utilisation, further development of CSP services was needed to support and improve TC experience and confidence with cord. Objectives To develop and implement a new service to help TCs with assessing complicated post-thaw data as an enhancement of CSP’s existing suite of offers. Methods The Post-Thaw Clinic (PTC) worked via a dedicated inbox manned by AN Registry operational staff; TCs submitted post-thaw data and quality queries to a panel of 5 experts from AN and NHSBT Cord Blood Banks (CBBs) for next-day holistic assessment of data to determine CBU suitability. The final decision remained with the Clinical Teams at the TCs. Customer feedback, national usage of CBUs and AN CBB utilisation rate were monitored. Results 100 queries for 79 patients were received by the PTC panel between April 2022 and May 2024. In 89% of cases progressing to workup, TCs took onboard the panel’s advice proceeding with their initial CBU or an alternative graft. CBU usage in the UK remained stable 2022-2024, providing an average of 9.8% of all stem cell products received. AN CBB’s utilisation rate saw a 33% increase from 0.46% in April 2022 to 0.61% in May 2024. It's domestic market share increased from 11.3% in FY21/22 to 25.2% in FY23/24 (figure 1). Discussion The PTC has been well received by UK TCs. Through providing comprehensive support with CBU quality evaluation, banks make a difference by building confidence and relationships with domestic TCs. This collective effort between registry and banks has resulted in stable CBU usage in the UK despite international trends of decline, supported national bank utilisation and played a vital role in supporting increased interest alongside recently published striking data (Horgan et al, 2023). In further development, “ask the expert transplanter” was launched in April 2024, facilitating TCs sending clinical queries to clinicians who transplant high volumes of CBUs.
