OBJECTIVE: To determine whether a communityinformed, language-concordant postpartum video education campaign, developed with community input, improves patients' knowledge of warning signs for postpartum maternal mortality (infection, hemorrhage, hypertensive disorders, and postpartum depression) compared with routine discharge procedures. METHODS: A single-center, investigator-blinded, parallelgroup randomized controlled trial of postpartum individuals who delivered at a large, urban, tertiary care hospital. Eligible participants were enrolled and completed a baseline knowledge questionnaire. After delivery, they were randomized to routine discharge education (control) or routine education plus video education (intervention). After discharge education, patient knowledge was again assessed in both groups before participants left the hospital. The primary outcome was the percentage of participants who showed improvement in their knowledge, measured by the number of correct questionnaire responses after education compared with their baseline, assessed as a binary outcome. A sample size of 150 (75 per group) was planned to detect a 25% absolute increase in the frequency of the primary outcome. RESULTS: From July to August 2022, 296 participants were screened and 200 were randomized (100 per group). Eightytwo percent of participants had college or graduate education, and 71.5% had commercial insurance. There was no significant difference in baseline characteristics. There was no statistically significant difference in the percentage of participants who improved their scores between the baseline and posteducation questionnaires (64.5% vs 50.0%, P5.09). However, the median posteducation questionnaire total score was significantly higher in the video education group (14 [interquartile range 12-15] vs 13 [interquartile range 12-14], P5.003). In addition, they more frequently reported that video education was "very helpful" (83.9% vs 72.5%, P5.23) and that they were "very satisfied" with their education (86.1% vs 75.5%, P5.29). CONCLUSION: Enhanced postpartum education through a novel video did not result in a statistically significant difference in frequency of improved score on the posteducation questionnaires but was associated with increased satisfaction with care.
