Abstract

OBJECTIVE

We conducted an analysis of online information on noninvasive prenatal testing (NIPT) provided by Japanese medical institutions recognized by the certification system (certified institutions) and other institutions (non-certified institutions).

METHODS

We identify institutional websites from google Japan that used three keywords related to prenatal testing (N = 37). Comprehensiveness was assessed using domestic and international guidelines. Quality was measured using the DISCERN instrument, and readability was evaluated using jReadability.

RESULTS

Among certified institutions, the mean comprehensiveness score was 7.36 out of 20, and the mean DISCERN score was 42.6 out of 80, categorized as "fair," although nearly half were rated "poor" or "very poor." Most websites required "lower advanced" reading proficiency. Websites from non-certified institutions showed higher comprehensiveness and readability than certified institutions.

CONCLUSION

NIPT-related information on certified institution in Japan is often insufficient in terms of quality. By contrast, non-certified institution, although ethically problematic, may provide more comprehensive and higher-quality information. Certified institutions should improve the quality and clarity of web-based communication to support patient's decision making.

INNOVATION

This is the first study to assess the NIPT-related websites in Japanese medical institutions. Critical informational gaps were identified, highlighting the need for trustworthy and readable online resources.
