Why should they die because they are pregnant? A critical review of the Lagos response to maternal mortality



Maternal mortality is defined as "the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental causes"[1]Of the approximately 328,000 females who died from pregnancy related causes in 2008, 99% were from developing countries [2] Haemorrhage, infections, pre-eclampsia/eclampsia, obstructed labour and unsafe abortion constitute almost 80% of all these maternal losses [2], while the remainder of the mortalities occur indirectly when pregnant women have existing co-morbidities like malaria, anaemia and HIV/AIDS during pregnancy [2].

This paper will critically analyse the actions and outcomes of the maternal mortality response in Lagos State [3] and compare with best practices and evidence based interventions from other developing countries.  The state is situated in the South-western part of the country, bordered by the Atlantic Ocean to the south, an international corridor to Benin Republic on the west, Ogun state to the north and east [4] (See Appendix).  The 2006 national population census puts the population of Lagos at 9, 013,534 [5], but this value has been widely disputed [6],as the State Government claims that a more reliable figure is 17,553,924, with women making up 8,437,901 [7].  85% of the population live in metropolitan Lagos, which makes up only 37% of the land mass [7].  This large population may pose a big challenge in coping with the maternal health needs. 

The maternal mortality rate of Lagos state was 400/100,000 live births, as estimated by UNFPA in 2009 [8] , while the State Ministry of Health (SMOH), provides a higher estimate of 650/100,000 live births [9].  This disparity in baseline data in itself poses a big challenge in benchmarking progress, even though both estimations are lower compared to the national average of 840/100,000 live births [10].  This essay argues that efforts of the government are not concerted, not encompassing and are not “need focused”.

To delve into this issue profoundly, the conceptual model designed by McCarthy and Maine (1992) to classify determinants of maternal mortality will be used.  They grouped these determinants as: distant factors such as socio-economic status including the women’s status in the family and community (education, occupation, wealth, social and legal autonomy); intermediate factors such as reproductive status (age, parity, family planning), health care behaviour (belief in and use of modern health practices), health status of the woman, access to health services and unknown and unpredicted factors; and outcomes, for example pregnancy, complications, death or disability have proved essential over the years in analysing policies geared towards tackling the problem [11].  This framework has since been modified by UNICEF as a basis to design more recent programme strategies [12].

As regards the women in Lagos, they have very high literacy rates of 90% compared with a national average of 54%, most living in the urban areas while 6% who have no formal education live in the rural areas [8,13].  This high figure means that Lagos women are more inclined to making informed choices, but not in the rural areas, where women may not be adequately educated.  This high literacy rate may however be the reason for the state having the lowest fertility rate in Nigeria of 4 births/woman, with only 18% having been pregnant twice within 2 years prior to a 2008 survey [13].  28% of women within the reproductive age group use modern family planning methods.  Teenage pregnancy is also relatively low at 5.3% compared to the national average of 23% [13].   38% of women have comprehensive knowledge of prevention of HIV/AIDS [13], which is decision making on high sex risk behaviours, that predisposes them to the disease, which may affect pregnancy outcomes.

Pregnant women subsequently need to be able to access services, but some factors may prevent them.  Maine and Thaddeus (1994) previously identified three phases of delay for women who need to utilize maternal health services.  Phase I is delay in deciding to seek care, phase II is delay in identifying and getting to health facility and phase III is delay in receiving satisfactory and suitable treatment [14].  SOGON reported in a 2004 health needs assessment that women who did not access services because of delay in deciding to seek care was 41.6%, while those who did not because of difficulty in transportation was 18.6% [15], though this may be attributed to the riverine nature of most of Lagos.  Delay from receiving satisfactory and suitable treatment on reaching the health facility was seen in 14% of cases [15], which shows that there is still a gap service provision in existing facilities.  In Lagos, 88% of women received ante-natal services from skilled attendants in the five years prior to the NDHS, which is a significant increase from the 43% that received professional care in 2004 [13].  This improvement may be attributed to the free ante-natal care instituted by the government, even though spontaneous vaginal delivery and operative delivery have service charges of N12,000 (£47.24) and N50,000 (£196.85) attached to them, which I reckon is still relatively expensive, as  39.7% of Lagos women could not access care because they lacked funds [13].  83% of women, who accessed care, were subsequently delivered by skilled providers [13].  The major cause of maternal deaths amongst Lagos women over recent years has switched from pre-eclampsia/eclampsia to haemorrhage probably because Magnesium sulphate gained grounds in the Lagos urban health facilities [8,15].

This essay argues that government response is not adequate, as it is not based on any defined policy document focused on strategies to reducing maternal mortality, short of the government providing free ante-natal services in public hospitals [8], and this in itself does not aid strategic planning.  The State tailored her response to training skilled health workers, provision of proper equipment and construction of referral centres in case of complications.  Capacity building for health staff working in the various obstetrics and gynaecology departments across the state were carried out with a focus on emergency obstetric care [16].  Topics covered epidemiologically significant causes of death in obstetrics and by May 2011, 1,103 medical personnel had been trained, including 319 doctors and 784 nurses [17].  For referral centres, six 110 bed capacity maternal and child centres (MCC) were constructed to collectively provide an additional 66% capacity to the available state maternal health specialist facilities [16].  Training on community engagement to bolster staff relationship with pregnant women and to improve reaching out to women not accessing care in the rural community has not been done, even though this cohort are the most deprived. 

The 1992 McCarthy and Maine approach is proposed as baseline in this essay.  They argue that interventions to tackle maternal mortality must focus on achieving three intermediate outcomes, which are: reducing chances that a woman gets pregnant; reducing the tendency of a pregnant woman experiencing any serious pregnancy or delivery complication; and improving outcomes for women with complications [11].  Furthermore, the 1994 mother-baby package identified four crucial safe motherhood strategies as pillars which mould program design - family planning; antenatal care; clean/safe delivery and essential obstetric care, all resting on foundations of equity for women, primary health care and basic maternity care [18]. Whilst these packages seem well grounded and all of their components are crucial in improving maternal health, they do not consider cross-cutting issues such as HIV/AIDS that may occur in pregnant women, poverty, gender based violence and so on.  More recently, the WHO in 2009 recommended the Integrated Management of pregnancy and childbirth as the complete package for dealing with maternal mortality.  This package has three core focuses: the health workers, health systems and health promotions [19].  The framework details routine, additional and specialised care for pregnant women at pregnancy, childbirth and postpartum; outlines place of care, providers, interventions and commodities that should be available for each type of care; home care, family, community and workplace support for the woman during pregnancy and childbirth; care for the woman before and between pregnancies, especially in adolescent period; and suggests policies for pregnant women who do not want the child (safe abortion and post-abortion care) [19].   I reckon that this is the way forward.

Some evidence based interventions that may prove useful in Lagos would now be discussed.  Focused ante-natal care, as evidenced in a multinational study, recommends that four visits is satisfactory for low-risk pregnancy and may reduce number of attendees [20].  This would ensure that women who need attention the most receive it and reduce cost of intervention, especially in a low resource setting like Lagos.  Post-delivery care is crucial, yet often neglected, even though a sizeable proportion of maternal deaths happen at this stage [21].  The advent of the abortifacient, misoprostol has however improved abortion outcomes in many developing countries [22], and needs to be scaled up to reach rural health facilities of Lagos.  “Task shifting - a process of delegation, whereby tasks are moved where appropriate, to less specialized health worker” [23] - may also be useful in Lagos, as it has worked in districts in Senegal [24] to tackle the problem of dearth and mal-distribution of Lagos medically trained skilled health care professionals [25], who prefer the luxury of urban life to the simplicity of rural living.  This would reduce the dependence on the expensively trained medical doctors, and allow wider coverage of services.  For interventions focused on maternal nutrition, vitamin A and iron supplementation have been shown to reduce incidence of anaemia.  This is evidenced by results in Nepal where there was a 40 % reduction of MMR with the intervention [26].  Iron supplementation is also important in reducing maternal anaemia [27].  Less anaemia means lowered risk of death from post-partum haemorrhage, which was previously acknowledged as a major cause of maternal deaths.  Preventing haemorrhage rather than treating it may reduce the proportions of women dying from the condition.  Malaria also predisposes a pregnant woman to anaemia, therefore prevention, with long lasting insecticide treated nets and sulphadoxine-pyrimethamine twice during pregnancy [28] - which is only given free to Lagos women who deliver in public facilities - [8] should be scaled up to include private hospitals, thereby expanding coverage, and reducing the impact of the disease.  As regards the cross-cutting issue of HIV/AIDS, collaboration between existing HIV/AIDS and maternal mortality rate (MMR) reduction strategies will be crucial in ensuring that specialised care required by pregnant women living with HIV/AIDS is provided for [29].  Furthermore, laws protecting women against gender based violence also need to be instituted, as violence during pregnancy usual perpetuated by male partners may lead to sepsis, suicide, homicide spontaneous and induced abortions [30].  Government subsidy on normal and operational delivery may also encourage service uptake.  Access may also be improved, especially in riverine areas, by establishing functional transport networks to commute pregnant women to facilities when needed.

In this “New Public Health” era in which the field operates now, the Ottawa charter (1986) forms the action framework on which the paradigm is structured, building healthy public health policy, creating supporting environment, developing personal skills, reorienting health services and strengthening community action are crucial in health promotion [31,32], in this case targeted at pregnant mothers.  Based on this, Lagos has made progress in reorienting health services and creating enabling environment, but without developing personal skills and strengthening community action through education, empowerment and engagement of the pregnant mothers themselves; and developing sustainable health policy focused on tackling maternal mortality and a framework on which to mark progress - especially towards targets set locally and towards global targets as set in the Millennium Development goals, which targets reducing maternal mortality ratio by three-quarters between 1990 and 2015 [33] -, the maternal mortality problem will not be solved.  Nigeria, as a whole reduced maternal mortality from 1,000 to 545 deaths/100,000 live births from 1990 to 2008, but is presently unlikely to meet its target of 250 deaths/100,000 live births [34].  Lagos with all the resources available at her disposal and as the centre for excellence in the country can make a valiant effort towards meeting this audacious target.  Attention should not only be given to the women who are attending and receiving maternal health services, but also to those women who are not accessing care and the socio-cultural factors limiting their access.  Cross-cutting issues including poverty, gender inequality and HIV/AIDS stigma still need to be addressed.  Reducing maternal mortality in Lagos would require a plethora of highly interconnected measures managed by different ministries, departments, agencies and development partners that would include periods long before the woman gets pregnant, during and after the pregnancy; and would also involve community engagement and unflinching government commitment. 

In conclusion, based on the above discussion, the response of Lagos state to maternal mortality is not adequate for the problem at hand.  No policy for baseline, no dependable data, no dedicated monitoring of programs, no analysis of impact and no dedicated attention to the root cause of the problem.   Indeed, no woman deserves to die because she is carrying out her sociological role as a wife and her physiological responsibility as a mother.
