To assess the trends concerning utilisation of maternal and child health (MCH) services before, during and after the Ebola outbreak, quantifying the contribution of a reorganised referral system (RS).

A prospective observational study of MCH services.

Pujehun district in Sierra Leone, 77 community health facilities and 1 hospital from 2012 to 2017.

MCH utililization was evaluated by assessing: (1) institutional deliveries, Cesarean-sections, paediatric and maternity admissions and deaths, and major direct obstetric complications (MDOCs), at hospital level; (2) antenatal care (ANC) 1 and 4, institutional delivery and family planning, at community level. Contribution of a strengthened RS was also measured.

At hospital level, there is a significant difference between trends Ebola versus pre-Ebola for maternal admissions (7, 95% CI 4 to 11, p<0.001), MDOCs (4, 95% CI 1 to 7, p=0.006) and institutional deliveries (4, 95% CI 2 to 6, p=0.001). There is also a negative trend in the transition from Ebola to post-Ebola for maternal admissions (−7, 95% CI −10 to −4, p<0.001), MDOCs (−4, 95% CI −7 to −1, p=0.009) and institutional deliveries (−3, 95% CI −5 to −1, p=0.001). The differences between trends pre-Ebola versus post-Ebola are only significant for paediatric admissions (3, 95% CI 0 to 5, p=0.035). At community level, the difference between trends Ebola versus pre-Ebola and Ebola versus post-Ebola are not significant for any indicators. The differences between trends pre-Ebola versus post-Ebola show a negative difference for institutional deliveries (−7, 95% CI −10 to −4, p<0.001), ANC 1 (−6, 95% CI −10 to −3, p<0.001), ANC 4 (−8, 95% CI −11 to −5, p<0.001) and family planning (−85, 95% CI −119 to −51, p<0.001).

A stronger health system compared with other districts in Sierra Leone and a strengthened RS enabled health facilities in Pujehun to maintain service provision and uptake during and after the Ebola epidemic.
