特朗普政府WISeR试点用AI审批老年人Medicare诊疗并引发拒付争议
Trump admin using AI to deny medical care for seniors in disastrous experiment
特朗普政府1月推出名为WISeR的试点，用人工智能对Medicare老年人的部分诊疗做事前授权或拒绝。该联邦医保此前不要求医生获得此类预先批准，媒体随后报道技术故障、决策与治疗延误、费解拒付，以及医生受挫和患者疼痛。电子前沿基金会本月早些时候经诉讼取得的联邦文件基本印证这些情况，有医疗服务提供者称项目是对人类的耻辱；政府问责局5月认定设立未遵循正当程序，但项目仍在推进并计划未来数年扩大。
In January, the Trump administration rolled out a pilot program that uses artificial intelligence to authorize or deny certain types of care for patients with Medicare—a federal healthcare program for seniors that previously hasn't required doctors to get any such pre-approval, called prior authorization.
Not long after, media outlets began relaying the disastrous outcomes: technical difficulties, long delays in decisions and care, puzzling denials, frustrated doctors, and patients suffering in pain. Those reports were largely confirmed earlier this month when the Electronic Frontier Foundation released a tranche of federal documents about the program, called WISeR, that the group obtained amid litigation. The documents included feedback from healthcare providers, including one who called the program "a disgrace to the human race" and reported seeing patients crying in pain as they waited for care.
Amid the worrying reports, lawmakers have been trying to get answers and shut the program down. Meanwhile, the Government Accountability Office determined in May that Trump officials did not follow proper procedure in setting up the program, calling its legality into question. Still, it appears to be moving ahead unabated, with plans to expand in the years to come.
