Risk-adjusted survival in liver transplant patients assessed and managed by a non-transplanting centre: South West Liver Unit experience

Background: Liver transplant services remain a scarce resource not reflective of geography or burden of liver disease within the UK. To address geographical concerns in the South West (SW), a devolved network model of care for liver transplantation was established in 2004 between the SW Liver Unit (SWLU) at Derriford Hospital, Plymouth and King's College Hospital, London. The SWLU has evolved to deliver both pre-transplant and post-transplant care for patients across the SW Peninsula. We determined whether risk-adjusted survival in patients assessed and managed at the SWLU compared with existing UK transplant centres.

Design: Retrospective analysis of records at National Health Service Blood and Transplant (NHSBT) for patients ≥18 years listed or undergoing first liver only deceased donor transplantation from 1 January 2006 to 31 December 2017. Data collected and used were in accordance with standard NHSBT outcome measures.

Results: We identified 8492 patients registered for first liver only transplant and 6140 patients who subsequently underwent transplantation. Of these, 215 patients listed and 172 patients transplanted were registered at the SWLU. The 1-year, 5-year and 10-year risk-adjusted post-listing survival for patients registered at the SWLU were 86%, 75% and 67%, respectively, with 1-year and 5-year risk-adjusted post-transplant survival 94.9% and 84.4%, respectively.

Conclusions: Risk-adjusted post-listing 1-year, 5-year and 10-year survival outcomes and risk-adjusted 1-year and 5-year post-transplant survival outcomes at the SWLU are good and comparable with the seven UK transplant centres. These outcomes provide assurance that care delivered by our regional programme is equivalent to well-established liver transplant programmes.
