Purpose: The goal of this article is to explore what online education and decision support tools are freely available to patients about prenatal screening. Methods: We (1) conducted an environmental scan using Google Trends to identify and evaluate prenatal screening search terms, (2) created a list of websites and YouTube videos that would be easily accessed by a searcher, and (3) characterized the information within those websites and videos, including an examination of their qualities as a decision support tool and a readability analysis. Results: Fifty websites, containing 62 unique educational resources, and 39 YouTube videos were analyzed. The websites were primarily educational, although the education was provided by a range of sources, including non-profit and for-profit organizations, universities, and governments (ie, public health departments). Readability scores of Patient Education Materials Assessment Tool for Printable Materials for the sites ranged from 50% to 92%, with a median score of 74%. Two of the websites we evaluated met all of the limited decision support standards we applied; 4 of the websites included patient stories or experiences, and 8 included some element of values clarification. Videos were more likely to include values clarification. Conclusion: The information available to patients online is variable. Although most is balanced and informative, much is difficult to read and missing key decision-making factors. Health care providers should work with patients to ensure they have basic comprehension of the prenatal genetic screening materials, possible result outcomes, and expected steps following a positive screening result.
