Objective: To evaluate the effect of a national referral system that aims to reduce maternal mortality rates through improving access to and the quality of emergency obstetric care in rural Mali (sub-Saharan Africa).
Methods: A maternity referral system that included basic and comprehensive emergency obstetric care, transportation to obstetric health services and community cost-sharing schemes was implemented in six rural health districts in Kayes region between December 2002 and November 2005. In an uncontrolled 'before and after' study, we recorded all obstetric emergencies, major obstetric interventions and maternal deaths during a 4-year observation period (1 January 2003 to 30 November 2006): the year prior to the intervention (P-1); the year of the intervention (P0), and 1 and 2 years after the intervention (P1 and P2, respectively).
