Care utilization
Ada intercepts before patients call anyone, search anything or head to the emergency department.
Before the PCP visit. Before the search. Before the decision. A patient notices something is wrong and opens Ada. Here’s how it works:
1. Patient describes symptoms to Ada
2. Ada’s clinical AI identifies a probable condition
3. Patients are presented with appropriate next steps
38.5%
of patients who planned an emergency department visit chose lower-acuity care after a single Ada assessment.
