Knowledge, Use, and Perceptions of Artificial Intelligence Among Health Sciences Students: Evidence from Costa Rican Universities

Background: Artificial intelligence (AI) is reshaping health sciences education worldwide, yet regional data from Latin America remain scarce. Understanding students’ AI literacy and perceptions is essential for developing informed curricular strategies. Methods: A cross-sectional online survey was conducted among 270 students from four Costa Rican universities across five health sciences programs. Descriptive and inferential analyses (ANOVA, Chi-square) examined AI knowledge, usage frequency, and perceptions of ethical integration in academic contexts. Results: Over 80% of respondents reported moderate or higher AI knowledge and frequent use of tools such as ChatGPT, mostly for academic support tasks. However, more than 90% had not received formal institutional training, and ethical awareness—particularly regarding misinformation and bias—was limited. Conclusions: Students demonstrate active engagement with AI despite minimal curricular exposure. These findings emphasize the need for structured AI training, faculty development, and equitable access policies aligned with global digital ethics frameworks to ensure responsible adoption within Costa Rican health sciences education.
