Ada Health vs Steer Health
Health systems can shortlist either. Ada's medical-quality page states EU MDR Class IIa with CE mark 0123. Steer's Halo page describes clinical symptom evaluation protocols, red flag detection and acuity-based routing to ER, urgent care or telehealth, without naming the protocol source, and carries one nurse testimonial about oversight. Steer claims 99.2% triage accuracy, 35% ER diversion and zero missed emergencies, and gives no method behind the figures. Ada's evidence is published and mixed. A 2023 JMIR mHealth emergency department study comparing Ada, WebMD, ChatGPT and physicians found Ada's triage advice at 62% agreement, 14% unsafe and 24% too cautious. A quality committee that wants to read a method before accepting a number would pass over Steer on evidence. A health system that wants results written back to its chart has Steer's platform page, which claims real-time bidirectional write-back with Epic, Cerner and 30+ other systems, against Ada's health-systems page, which says only that it integrates with your system.
