It ended the contract about a year before February 2026, around early 2025, saying the cost did not justify how little the robots were used. A regional newspaper reported the story on 17 February 2026, and the hospital's nurses' union added its own account on 13 March 2026. The union, the Washington State Nurses Association, said the robots needed escorts between floors and never delivered meaningful time savings. It also said nurses had no voice in the original purchasing decision. Diligent Robotics still reports nearly 100 robots operating in more than 25 hospital facilities, using its own activity counts; no independent outcome evaluation was located.
Measuring this evidence against Diligent Robotics' published, never-individually-checked score of 83.0 produces 79.8 — enough to cross out of the Exemplary band into Established. That finding was set aside for two reasons. This benchmark requires at least two independent sources before publishing a band-change finding, with one of them top-tier. The evidence located here — a regional news report and a nurses' union statement — does not include a top-tier source. The crossing also depends on a scoring bonus that disappears once enough categories fall below an exact threshold, in a score that had never been checked against evidence before. Diligent Robotics' published score of 83.0 is unchanged.
Separately, the AI lab Imbue confirmed its own published score of 81.4 this cycle, measured at 81.1, with no independent evidence located in either direction. Its Exemplary rating rests on seven of eight categories sitting at exactly the scoring formula's bonus threshold — the same structural pattern now visible in Diligent Robotics' case. Both are referred to a joint review of every organization whose top-tier score depends on that threshold.
