Knowledge on postnatal care among postpartum mothers during discharge in maternity hospitals in Asmara: a cross-sectional study

The early postnatal period is a dangerous time for both mother and baby where morbidity and mortality are highly prevalent if proper care is not done. Post natal care (PNC) knowledge has significant role in reducing such complications. In this study, the knowledge of postpartum mothers on PNC and its determinants were determined.

A cross-sectional quantitative study was conducted in postpartum mothers (PpM) who attended all maternal delivery services in Asmara. Data was collected by a structured questionnaire. All (n = 250) PpM who gave birth in December, 2017 were included in the study. Independent samples t-test and one way ANOVA were used to compare the scores in knowledge across categories of background characteristics using SPSS. Bonferroni post-hoc test was performed for variables that were found to be significant while using ANOVA tool. P-values less than 0.05 were considered as significant.

The percentage of PpM who cited vaginal bleeding, as a maternal danger sign, and fever, as a baby danger sign, were 83.2 and 58.8%, respectively. The majority (96%) of PpM responded the correct answer on where to go if they note any danger signs. In addition, more than nine tenth of PpM correctly identified injectable contraceptives (92.7%) and oral contraceptive (91.5%). The percentages of knowledge in recognizing the necessary nutrients ranged from 87.6% for carbohydrates to 46% for minerals. The percentages of correct knowledge regarding first baby bath, frequency of breast feeding, umbilical care, duration of exclusive breast feeding, need and purpose of vaccine were 40.1, 81.9, 77.4, 94.8, and 99.2% respectively. The mean PNC knowledge score was 24.89/60. The score of knowledge on postnatal care was found to significantly differ across the categories of residence (p < 0.001) and ethnicity (p = 0.015). An increasing trend of knowledge score was observed with increase in age group (p < 0.001), educational level (p = 0.021), gravida (p < 0.001) and para (p < 0.001).

Considerable gaps in knowledge regarding postnatal care among postpartum mothers were evident. Special attention should be laid on rural residents, single/living together, junior/below in educational level, primigravida/para, non-Tigrigna ethnicity, and 17 to 25 years old mothers.
