Postnatal care utilization within 48 h after birth and its determinants in northwest Ethiopia: a multilevel logistic regression analysis.

Postnatal care immediately after birth is a crucial component to save lives of mothers and the newborns. A paucity of evidence indicated that women's unwillingness to receive care after birth is a remained challenge in resource-limited settings in general and in Ethiopia in particular. This study aimed to assess the utilization of postnatal care within 48 h after birth and its determinants in northwest Ethiopia. A community-based cross-sectional study was conducted from October to November 2020. A total of 811 women who had birth within the last one year were involved in the study. Both random and fixed effects were reported using an adjusted odds ratio with a 95% confidence interval and p value of 0.05. The study revealed that 13.3% (95% CI 10.9-15.7%) of women attended postnatal care visits within 48 h after birth. Attending secondary and above education (AOR = 2.39; 95% CI 1.18, 4.84); health extension workers home visiting during pregnancy (AOR = 1.74; 95% CI 1.08, 2.82); birth order (AOR = 2.07; 95% CI 1.03, 4.14); place of delivery (AOR = 7.49; 95% CI 3.73, 15.06); and short distance to health facility (AOR = 4.19; 95% CI 1.64, 10.70) were significantly associated with postnatal care utilization within 48 h after birth. Postnatal care utilization within 48 h is low in rural northwest Ethiopia compared to findings from most resource-limited settings. The existing health system should consider multilevel intervention strategies focusing on maternal health education, engaging community health workers in health promotion, and ensuring physical accessibility of healthcare facilities to be more effective in improving postnatal care utilization within 48 h.
