Referral Pathway Fragmentation and Emergency Obstetric Delays in Malawi: A Multilevel Analysis of Health System Bypassing and Interfacility Transfer Times

Emergency obstetric referral in Malawi is often described as a single transfer from a peripheral facility to a district or central hospital, yet the pathway that women actually traverse is frequently fragmented by bypassing, informal re-routing and repeated interfacility moves. The indicator is treated as a system-level marker of reproductive-health service exposure rather than as a direct measure of obstetric delay. Across the 105 observations the mean was 27.32 and the standard deviation was 16.748, with country values ranging from 3.65 in Chad to 62.90 in South Africa. The framework specifies three delay-generating mechanisms: bypassing at the point of first contact, transfer-time inflation between facilities, and pathway truncation when women are absorbed into facilities outside the formal referral hierarchy. It proposes a two-level model in which interfacility transfer times are nested within bypassing episodes, and it argues that fragmentation should be measured as a property of the pathway rather than of any single facility. The contribution is a transferable analytic architecture for studying referral fragmentation in low-resource obstetric systems, together with a demonstration of how existing survey indicators can be used to characterise the system-level context in which fragmentation occurs.
