Notes: PPH: postpartum hemorrhage; CEmONC facilities: facilities with comprehensive emergency obstetric and newborn care; BEmONC facilities: facilities with basic emergency obstetric and newborn care; QALY: quality-adjusted life years†Incremental cost of Uniject relative to the traditional use of oxytocin in ampulesΩExpressed as the proportion of the gap (between the ideal of 100% of women receiving oxytocin and the proportion currently receiving it) which could potentially be reduced by using Uniject instead of oxytocin in ampules.For the probabilistic sensitivity analysis (PSA) the “probability of PPH without oxytocin”, the “conditional probability of severe PPH (given PPH)”, the “Risk of hysterectomy due to severe PPH”, the “Relative risk of PPH when receiving oxytocin” and the “Oxytocin effectiveness (% gap reduction)” were assumed to follow a Beta distribution. Alpha and beta parameters were approximated considering the mean the main estimate and as standard deviation the 10% of the mean value. The “incremental cost of Uniject” was assumed to follow a Gamma distribution. Alpha and beta parameters were approximated in these cases considering the mean as the main estimate and as standard deviation the 25% of the mean value.Global parameters: Base case values, ranges used in the sensitivity analysis and data sources.
