State of the World's Midwifery 2014 - Nigeria: Achieving MDG 5
Publication date: 2014
Nigeria Achieving MDG 5 Maternal Mortality With a population of over 171 million in 2013i, Nigeria is the most populous country in Africa. It is also among the top ten countries in the world when it comes to maternal mortality. With an estimated 36,000 women dying in pregnancy or childbirth each year, Nigeria accounts for almost 13% of the global maternal death burdenii. Over the last twenty years, Nigeria has made significant progress in reducing the maternal mortality ratio. According to the NDHS 2008, the country that year had a MMR of 545 per 100,000 live birthsiii. A concerted effort is required to reach the MDG goal of an MMR of 300 (or just under 20,000 annual deaths) by 2015. More than 70% of all maternal deaths in Nigeria are due to just four conditions - hemorrhage, eclampsia, sepsis and abortion complicationsiv. An estimated 5,500 of these deaths are among adolescentsv. Family Planning and Maternal Health vi,vii,viii,ix In addition to a 75% reduction in the MMR, MDG5 also calls for universal access to reproductive health care by 2015. The following shows current coverage with key reproductive services in Nigeria. Family Planning Only 9.8% of Nigerian women use modern family planning methods, 16.1% have an expressed unmet need for family planning (DHS 2013). Antenatal Care 51% of pregnant women had at least 4 antenatal care visits. Skilled Delivery Care As measured by the latest MICS survey, only 38% of the annual 6.6 million births in Nigeria were assisted by a skilled attendant. Estimated Impact of Universal Access to Reproductive Health Family Planning Providing women with access to family planning and making it possible for them to decide how many children they want and when to have them, reduces the overall number of deaths by reducing the number of women dying due to pregnancies they never intended to have. Meeting only 25% of the unmet demand for family planning in Nigeria, i.e., supplying 1.0 million additional women with access to family planning would reduce the number of unintended pregnancies by 370,000 and deaths related to unintended births and abortions by about 1,300. Maternal Health Most maternal deaths are preventable, as the health-care solutions to prevent or manage complications are well known. The following interventions and drugs tackle the four top causes of maternal deaths in Nigeria: Prevention and management of hemorrhage - Oxytocin/Misoprostol Prevention and management of eclampsia with Magnesium sulfate Prevention and treatment of sepsis with Clean delivery kits and antibiotics Number of Maternal Deaths that Could be Prevented Providing all women with the required maternal health medicines and supplies would prevent an additional 19,000 deaths, reducing the annual number of deaths to about 16,600 and the MMR to 260, enabling Nigeria to not only reach but significantly exceed its MDG goal of 300. In addition, these interventions would have a significant impact on child, and in particular, newborn mortality. Currently Nigeria has about 260,000 neonatal deaths a year. About 13% of those, or 34,000, could be prevented by providing women with the above life-saving interventionsx. Essential Drug Requirements and Costs Maternal Health Drugs For Universal Coverage Drug and commodity requirements to provide the care detailed above would cost about $19 million, $3 million for additional FP supplies and $16 million for maternal health (detailed calculations are available in Annex 1). Required health system investments Additional investments will be necessary to strengthen countries’ logistics systems and to ensure that health providers (both at facility and community level) know how to administer these drugs. Annex 1. Methodology The following describes the methodology used to arrive at the impact and cost estimates in the factsheet. Maternal Mortality The number of current annual maternal deaths was calculated using the 2008 maternal mortality ratio from the Nigerian 2008 DHS survey applied to the estimated number of births in 2013 (based on population data from the UN Population Division). Deaths Prevented through Family Planning The number of unintended pregnancies averted was calculated by comparing the number of pregnancies that would have happened if the 1 million (25% of the 4 million women with currently unmet need in Nigeria) had not been able to access contraception to the number of pregnancies that would occur if these women used contraception (i.e. only experienced pregnancies due to failure of their chosen method). It was assumed that 40% of all women would have gotten pregnant if not using contraception. The average failure rate of contraceptives was estimated to be 3%. Based on regional data collected by the Guttmacher Institute for its 2014 update of “Adding It Up” it was estimated that only about 49% of unintended pregnancies would be carried to term, 38% would be aborted and 14% would end in a miscarriage. Note: Family planning reduces the absolute number of maternal deaths in a country but since it reduces both numerator AND denominator of the Maternal Mortality Ratio (defined as deaths per 100,000 live births) the reduction in maternal deaths caused by family planning is not reflected in the MMR. The estimated reduction in number of deaths required to achieve the country’s MMR goal differs therefore slightly depending on the assumption made about the number of births. The estimate in the first paragraph uses the current number of births, while the estimate in the Estimated Impact paragraph is based on a lower number of births (originally projected number of births minus unintended births averted through the provision of contraception to women with unmet need). Deaths Prevented through Maternal Health Interventions It was assumed that half of the women currently covered by skilled birth attendance, i.e. 25%, had access to the three live- saving drugs. This coverage was then scaled up to 100%. The following effectiveness data were used in estimating the expected reduction in maternal deaths: Intervention Effectiveness Source 1.

PAC management - Misoprostol 50% The MMR after FP and MH scale-up was calculated by dividing the remaining number of maternal deaths by the number of births expected at the new contraceptive prevalence level (current 6.6 million births annually minus 180,000 averted through increased use of family planning. Cost Estimates Family Planning Unit costs for the different supply methods were taken from UNFPA’s RH Interchange database and multiplied by the amount required to provide one couple-year of protection (CYP). It was assumed that 15 cycles of the pill, 120 condoms and 4 injectables would provide one CYP. IUDs and Implant were assumed to provide 3.5 years of protection or CYPs. Their cost was thus divided by 3.5. The RH Interchange price for implants ($18.80) was replaced with a cost estimate per implant of $8.50 to reflect the recent price reduction seen, but not yet reflected in the database, due to the introduction of Sino- Implants. Drug and supply cost for male and female sterilization came from calculations carried out by the Guttmacher Institute for its Adding It Up 3 publication using UNFPA’s RHCT costing tool with updated 2013 prices. It was assumed that new users would adopt methods based on the current modern method mix. Cost Estimates Maternal Health Interventions Based on WHO treatment guidelines the following drugs and supplies were costed using drug prices from both the MH International Drug Price Indicator and the UNICEF Supply Catalogue.
