LA County Public Health will show alerts to doctors inside OpenEvidence searches

What was announced

The Los Angeles County Department of Public Health (DPH) and OpenEvidence announced a collaboration on July 23, 2026. OpenEvidence is an AI-powered clinical decision support platform, meaning a tool that helps doctors look up medical evidence while they work. According to the announcement on openevidence.com, the goal is to help physicians quickly find official county public health resources when they search for clinical information.

In practice, when a physician in LA County searches the platform for certain public health topics, OpenEvidence will show related messages written by LA County Public Health. The announcement does not list which topics are included.

What doctors will see

The messages link clinicians to local public health resources and health alerts. The announcement names three areas: reportable diseases (illnesses that health officials track closely), outbreaks, and other issues where timing matters.

Barbara Ferrer, the department's director, gave measles and TB as examples. Her point was that a search on such a condition should not stop at general information. It should lead to a next step, and she said she wants that step to be "easy to find and easy to take."

The announcement does not describe how the messages will look on screen or how often they will appear.

Why local guidance needs a delivery route

National medical advice is useful, but a county health department knows what is happening in its own area. Ferrer said physicians often need local guidance at the same moment they are working through a clinical problem. A general search tool, left alone, may not surface it.

Travis Zack, OpenEvidence's chief medical officer, described the problem from the other side. Local health departments put a great deal of effort into guidance that is actually useful. Then they often must spend more effort getting clinicians to notice it. His argument is that this partnership adds practical help without making the doctor search any further.

The idea is simple. Instead of asking busy doctors to visit a health department website, the health department's message meets them inside a tool they already use.

Building on New York City

This is not the first time OpenEvidence has tried this. The announcement says the effort builds on the company's experience reaching physicians with public health messages in New York City, in partnership with that city's health department. It gives no results from that work.

The release also frames the LA project as part of a broader push by the county to strengthen routine and emergency public health readiness. The department describes itself as one of the largest public health departments in the United States, serving more than 10 million residents. Its work includes infectious disease surveillance, vaccination campaigns, environmental health rules and community health promotion.

What to keep in mind

This is an announcement, not a report of results. The two organizations say they plan to evaluate the effort so they can refine future messages and find other areas where local guidance can be made easier for physicians to find. Until that evaluation exists, how well it works is unknown.

Readers should also note who wrote the announcement. It was issued jointly by the two partners, and the company describes itself as the most popular AI for doctors in the United States and says independent studies back that up. Those are the company's claims, and the release does not name the studies. OpenEvidence says it is free for verified U.S. clinicians, so the partnership does not appear to add a cost for doctors.

For patients, the likely benefit is indirect. You will not see these messages yourself. If it works, your doctor may simply have local advice at hand sooner. An AI tool's answer is still a starting point, and a clinician should confirm it.
