The chatbot, Legion, can renew 15 lower-risk maintenance medications that have already been prescribed by a clinician and can prescribe them. The program is limited in terms of the medications it covers and the conditions patients must meet to qualify. To use the system, patients must opt-in, verify their identity, and prove they already have a prescription. They are asked about their symptoms, side effects, and efficacy of the medication, along with questions about suicidal thoughts, self-harm, severe reactions, and pregnancy. The chatbot can renew these medications once or after 10 refills or after six months. However, there are concerns that the system may not be able to accurately automate even routine aspects of psychiatric care. Some experts believe this could lead to an "epidemic of over-treatment" in psychiatry, with some patients staying on medication longer than they need to. They also question whether any AI system can understand the unique context and factors that go into a person's medication plan.
