This retrospective query-log study describes what Latin American physicians ask a semantic clinical search platform developed by Arkangel AI. Over 13 months, from May 2025 to June 2026, the analysis covered 235,803 queries from 9,443 physicians in 20 countries, classified into a 10-category clinical taxonomy and reported following STROBE.
The activation rate was 84.4%, and each physician submitted a mean of 29.6 queries, with broadly similar volume across countries. Management plan (35.6%), differential diagnosis (20.6%), and work-up and test selection (11.4%) together accounted for 67.6% of queries, and this hierarchy held in all 17 countries with enough volume for country-level analysis. The study is descriptive and does not measure clinical accuracy or patient outcomes; it is a preprint not yet peer reviewed.
