Medical interpreters in St. Louis

Opalite recorded over 90% fewer errors than certified medical interpreters in its blinded validation study. The study compared Spanish, Mandarin, and Cantonese clinical dialogue and also reported over 98% fewer major and critical errors. Those are results from the tested conversations, not a measured error rate for every language or every St. Louis facility.

Providers in St. Louis covered by Title VI or Section 1557 must give patients with limited English proficiency meaningful access to care. When interpretation is needed, a qualified interpreter is required. Opalite is designed to support these obligations.

About 65,532 residents age five and older in the St. Louis metro area speak English less than very well, or 2.5% of that age group. In total, 194,233 residents speak a language other than English at home. These figures come from the 2024 American Community Survey 1-year estimates. Speaking another language at home does not by itself mean someone needs an interpreter.

The three largest non-English language categories in the St. Louis metro area are Spanish (60,413), Chinese (incl. Mandarin, Cantonese) (16,508), and Serbo-Croatian (14,486). These are household language counts for residents age five and older from the 2024 American Community Survey 1-year estimates. Some Census categories combine several languages, so a category total should not be read as a count for just one of them.

Opalite treats patient conversations as protected health information and signs a business associate agreement with every customer. For St. Louis teams reviewing its security practices, the safeguards include SOC 2 Type II audited controls, encryption in transit and at rest, and access logs. Patient health information is never used to train the models.
