UNOS organ matching runs on fragile legacy software that crashed 17 days total

The computer system that matches every donated organ in the US to a waiting recipient was built decades ago and has accumulated 17 days of total downtime since 1999. A 2021 US Digital Service report titled 'Lives Are at Stake' found that the OPTN contractor (UNOS) 'lacks sufficient technical capabilities to modernize their systems,' that 'core systems are fragile,' and that 'system uptime is insufficient for a life-saving system that depends on consistent operation.' The system relies on manual data entry, has had programming errors that required reprioritizing patients, and sometimes takes up to a year to reflect policy updates in code. When the system goes down, organ matching reverts to phone calls and manual coordination, extending cold ischemia time and increasing the risk of organ discard. A 2022 HHS OIG audit found 'multiple, basic cybersecurity failures,' and UNOS refused government requests to audit their code. This matters because every hour of delay in matching reduces organ viability—hearts survive only 4-6 hours outside the body. The system persists in this state because UNOS held a monopoly federal contract for 40+ years with no competitive pressure, and the 2023 law allowing multi-contractor OPTN operations is only beginning implementation.
