Determinants of maternal transportation mode and travel time for timely emergency obstetric care in selected public hospitals, Addis Ababa, Ethiopia, 2025

• Only 35.7% of mothers used ambulances during obstetric emergencies. • Average travel time to hospitals was approximately 51 minutes. • Urban residence and referral coordination increased ambulance use. • Prior knowledge of emergency transportation service contact numbers boosted ambulance utilization. • Second delay affected 27% of mothers due to transport inefficiencies. Inadequate transportation infrastructure and ineffective emergency transport services remain critical barriers to timely obstetric care in low- and middle-income countries, particularly in Sub-Saharan Africa. In Ethiopia, despite efforts to expand ambulance coverage, many pregnant women still face delays in accessing emergency obstetric services, contributing to preventable maternal morbidity and mortality. This study aimed to assess determinants of maternal transportation mode and travel time for emergency obstetric care among pregnant women attending selected public hospitals in Addis Ababa, Ethiopia. An institutional-based cross-sectional study was conducted from June to July 2025 across three public referral hospitals in Addis Ababa. Data were collected through a pre-tested structured questionnaire. Of the 319 mothers selected, 311 provided complete responses, yielding a response rate of 97.2%. Analysis was conducted exclusively on these respondents. Descriptive statistics summarized participant characteristics, and logistic regression was employed to identify associations between transportation mode and influencing factors. Statistical significance was set at p
