RESUMEN
In rural sub-Saharan Africa, preventable delays in accessing emergency care remain a dominant factor in maternal and neonatal deaths. The MOMENTUM study is a pragmatic cohort investigation designed to measure the "Three Delays", i.e. delays in recognizing need for care (Type 1), reaching care (Type 2), and receiving care (Type 3) within a remote island health system on Lake Victoria, Kenya. The study utilizes an adaptive methodology to provide actionable data for a locally-directed "Health Navigation" intervention. We present analysis of 56 maternal and neonatal emergency cases occurring between January 2019 and February 2020. The mean Total Delay Interval (Type 1-3) reported was 39.3 ± 32.3hours. Notably, 18 cases in this cohort resulted in a neonatal (n = 16) or maternal death (n = 2). Sub-analysis indicates significant delay interval reductions associated with involvement of a "Health Navigator" in emergency care coordination for Type 2 Delay Intervals (0.5 ± 0.3 vs. 1.2 ± 1.1 hrs., p = 0.002) and Type 3 Delay Intervals (17.9 ± 14.1 vs. 32.9 ± 33.7 hrs., p = 0.030). Prolonged delays, complex barriers, and high mortality highlight the fraught nature of maternal emergencies in this remote setting. We discuss practical considerations for application of the Three Delays model, and avenues for further investigation.
