Abstract
OBJECTIVE
This study aimed to assess the use of a standardized prenatal genetic testing educational video and its effects on patient uptake of prenatal testing, patient knowledge, decisional conflict, and decisional regret.
STUDY DESIGN
This was an Institutional Review Board-approved randomized controlled trial. Patients were randomized to intervention (standardized video education) or control (no video education). The video education group viewed a 5-minute educational video on genetic testing options, and the control group did not review the video. Both groups answered validated questionnaires to assess maternal knowledge (Maternal Serum Screening Knowledge Questionnaire [MSSK]), conflict (Decisional Conflict Scale [DCS]), and regret (Decisional Regret Scale [DRS]). The primary outcome was genetic testing uptake; secondary outcomes were knowledge-based test score, and level of decisional conflict and regret.
RESULTS
We enrolled 210 patients between 2016 and 2020, with 208 patients randomized, 103 patients in the video education group and 105 patients in the control group. Four patients were excluded from the video education group for missing data. Video education was associated with a 39% lower chance of prenatal testing compared with patients who did not receive video education, (odds ratio 0.39, 95% confidence interval 0.16-0.92). Patients in the video education group had higher mean MSSKQ scores by 2.9 points (8.5 vs. 5.7, p < 0.001), lower Decisional Conflict Scores by 7.3 points (31.5 vs. 38.8, p < 0.001), lower Decisional Regret Scores by 5.4 points (23.8 vs. 29.2, p < 0.001).
CONCLUSION
We found that video education on prenatal genetic testing improved patients' knowledge, decreased testing and decisional conflict and regret regarding testing. This may indicate improved understanding of testing options and more informed decisions that align with their personal values and beliefs. This standardized video can be easily implemented in clinical practice to increase patient understanding and support decisions that align with patient's values.
KEY POINTS
· A standardized educational video improves patient knowledge about prenatal testing options in pregnancy.. · Video education decreases testing and decisional conflict and decisional regret in pregnancy.. · A standardized educational video may be used in the clinical setting to educate patients on testing options and help them make informed decisions about testing..
