Pre-eclampsia Educational Tool Impact on Knowledge, Anxiety, and Satisfaction in Pregnant Women: A Randomized Trial

This study aimed to evaluate the impact of educational tools concerning pre-eclampsia on knowledge, anxiety, and women's satisfaction.

The investigators conducted a randomized controlled trial from March to July 2014 at the Centre Hospitalier Universitaire de Sherbrooke (Sherbrooke, QC) by comparing ambulatory pregnant women (20-32 weeks of gestation) who were receiving educational tools on pre-eclampsia with control patients who received routine care. Tools consisted of an informative pamphlet, a video, and a pictographic magnet, all validated by a multidisciplinary team. The primary outcome was global knowledge (number of correct answers on 35 items) about the disease after 1 month, as assessed by questionnaire. Secondary outcomes included anxiety regarding pre-eclampsia and satisfaction concerning the different tools (a 1-6 Likert scale was used).

Among 362 pregnant women approached for the research, 269 were randomized. After 1 month, 247 questionnaires (92%) were filled and analyzed: 122 from the control group and 125 from the intervention group. Baseline characteristics were similar between the groups. Patients who received the tools scored significantly higher on global knowledge (70.1% ± 19.2% compared with 51.1% ± 23.4%; mean difference of 19.0%; P < 0.001). Anxiety scores regarding pre-eclampsia were similar between the groups, with a mean of 2.40 out of 6 for the control group and 2.53 out of 6 for the intervention group (equivalence test, P < 0.001). High score levels of satisfaction for the pamphlet and video were found: 5.1 out of 6 and 5.2 out of 6, respectively.

These well-received educational tools for pregnant women increased their knowledge about pre-eclampsia without increasing their anxiety about it. Women reported the highest satisfaction for the tools.
