What's out there for parents? A systematic review of online information about prenatal microarray and exome sequencing.

ABSTRACT

OBJECTIVE: To identify what online patient information (presented in English) is available to parents about prenatal microarray (CMA) and exome sequencing (ES), and evaluate its content, quality, and readability. METHOD: Systematic searches (Google and Bing) were conducted, and websites were categorised according to their purpose. Websites categorised as patient information were included if they were in English, directed at patients, or were a text, video, or online version of an information leaflet. Author-developed content checklists, the DISCERN Genetics tool, and readability tests (the Flesch Reading Ease Score, the Gunning Fog Index, and the Simple Measure of Gobbledygook Index) were then used to assess those sources of patient information. RESULTS: Of the 665 websites screened, 18 met the criteria. A further 8 sources were found through a targeted search of professional organisations, resulting in 26 sources available for further evaluation. In general, this was found to be low in quality, omitted details recommended by national or international guidance, and was written at a level too advanced for average readers. CONCLUSION: Improvements should be made to the content, quality, and readability of online information so that it both reinforces and complements the discussions between parents and clinicians about testing options during pregnancy.
