Implausible algorithm output in UK liver transplantation allocation scheme: importance of transparency

Algorithm-based allocation of resource-limited health-care interventions is growing; however, concerns over transparency and bias have restricted its use.1 Transparent algorithms can be readily explained, allowing patients and clinicians to clearly understand the basis for decision making.2 In 2018, the Transplant Benefit Score (TBS) was introduced to allocate deceased donor livers to patients with chronic liver disease and primary liver cancer (hepatocellular carcinoma) on a national basis. Patients might also undergo transplantation for acute liver failure, although these patients are allocated organs via a different process.
