Background: The third Sustainable Development Goal aims to reduce maternal and newborn deaths. Pregnant women’s understanding of danger signs is an important factor in seeking timely care during emergencies. We assessed knowledge of obstetric danger signs using both recall and understanding of appropriate action required during obstetric emergencies.Methods: This was a cross-sectional study among pregnant women attending antenatal clinic at Bhutan’s largest hospital in Thimphu. Recall was assessed against seven obstetric danger signs outlined in the Mother and Child Health Handbook (7 points). Understanding of danger signs was tested using 13 multiple choice questions (13 points). Knowledge was scored out of 20 points and reported as “good” (≥80%), “satisfactory” (60 – 79%) and “poor” (<60%). Association between knowledge score and participant characteristics were tested using Chi-square, Fisher’s Exact and t-tests. Corresponding non-parametric tests were performed where appropriate. Correlation between participant characteristics and knowledge score as well as number of danger signs recalled was tested using Pearson’s correlation coefficient. Results with p<0.05 were considered significant.Results: Four hundred and twenty-two women responded to the survey (response rate = 96.0%). Mean (±SD) knowledge score was 12 (±2.5). Twenty women (4.7%) had “good knowledge”, 245 (58.1%) had “satisfactory knowledge” and 157 (37.2%) had “poor knowledge”. The median number of danger signs recalled was 2 (IQR 1, 3) while 68 (20.3%) women could not recall any danger signs. Women were most knowledgeable about pre-labour rupture of membranes (96.0%) and least knowledgeable about spotting during pregnancy (19.9%). Knowledge level was significantly associated with reading Mother and Child Health Handbook, mother’s education level, husband’s education level, number of antenatal care visits, gestational age and past surgery on reproductive tract. Both knowledge score and number of danger signs recalled significantly correlated with the period of gestation. Conclusions: Most pregnant women had satisfactory knowledge score but recognized the appropriate actions warranted during obstetric emergencies. The MCH Handbook has played a significant role in improving knowledge and understanding of danger signs.
