systems and not focused on disease

specific approaches to health

Three reasons

 

1. Ownership, intent, of SDGs

2. Epidemiology and temporal trends

3. Sustainability

1. Ownership, intent, of SDGs

2. Epidemiology and temporal trends

3. Sustainability

SDGs must be…universally applicable to all countries while taking into account different national realities, capacities and levels of development and respecting national policies and priorities

§  Definitionally focused on building approaches that are sustainable §  We cannot do this without building a foundation §  We cannot replicate vertical programs forever

decomposition is a method with a game theory foundation that allows for decomposition of changes in a variable because of diff erent contributory factors. Specifi cally, to assess the eff ect of these six factors on changes in under-5 deaths from 1990 to 2013, we constructed 64 scenarios in which all six factors took on values from either 1990 or 2013 in each specifi c scenario.

To compute the eff ect of any one factor, we assessed 32 pairs of scenarios in which all fi ve remaining factors had the same values. For each pair, we then calculated the change in under-5 deaths, for which only the factor of interest changed value, and used this as a measure of the contribution of this specifi c factor to the change in under-5 deaths. The average of the changes in all 32 pairs of scenarios was the contribution of one factor. We repeated the same process for all six factors.

We used the above equation to predict annualised rates of change for each country from 2000 to 2013 with recorded changes in income per person and maternal education and counterfactual levels of HIV in the absence of inter vention. We generated counterfactual

HIV death rates with the improved EPP-Spectrum models for GBD 201339,40 by setting prevention of mother-to-child transmission, co-trimoxazole prophylaxis, and antiretroviral therapy (ART) to zero for all years. These predicted rates provided an estimate of the eff ect of changes in income per person, education, and the long-term secular trend by GBD super-region on the basis of a comparison with observed rates of change.

Scenarios for under-5 mortality in 2030We developed four scenarios to predict the under-5 mortality rate in 2030 on the basis of the distribution of observed annualised rates of change from 2000 to 2013. Scenario one used the observed rate of change from 2000 to 2013 for each country to project to 2030. We assumed child mortality rates in any country with an increase in mortality in this time stayed at a constant level during the projection period. In scenario two, we applied the best 75th percentile rate of change in all countries from 2000 to 2013. In scenario three, all countries had a rate of change corresponding to the best 90th percentile, and in scenario four, to the best 95th percentile rate of change. We used observed rates of change for all-cause mortality by detailed age groups (early neonatal, late neonatal, postneonatal, and childhood deaths at age 1–4 years) to generate scenarios for the age composition of under-5 deaths. Our predictions of the number of deaths were based on these predicted rates and UN Population Division fertility forecasts.46 We then rescaled predicted age-specifi c and sex-specifi c mortality to match the predicted all-cause under-5 mortality rate in 2030. For analyses, we used Stata (version 13.1), R (versions 2.15.2, 3.0.1, and 3.0.2), and Python (version 2.7.3).

cause-specifi c death rate are necessary to sum to all-cause mortality using the CoDCorrect algorithm.16 To ensure they do sum to all-cause mortality, at the level of each draw from the posterior distribution of each cause of death for a specifi c country, year, and age group, the sum of all causes was rescaled to equal a draw taken from the uncertainty distribution of all-cause mortality for that country, year, and age group.

Causes of maternal deathWe disaggregated maternal deaths into nine causes: maternal haemorrhage, maternal sepsis and other pregnancy-related infections, hypertensive disorders of pregnancy, obstructed labour, abortion, other direct maternal disorders, indirect maternal disorders, HIV, and late maternal deaths. To estimate the diff erent causes of maternal death, we completed a systematic review (appendix) to identify data to inform which proportion of total maternal deaths is due to each cause. Additionally, we incorporated all vital registration and

sample registration data that provided ICD-coded detail for maternal causes (appendix). We identifi ed 61 studies and, after processing, included 943 site-years of vital registration, sample registration, and maternal mortality surveillance data.

We modelled the proportion of maternal deaths for all causes except HIV using DisMod-MR (version 2.0), which is a Bayesian meta-regression tool developed for the GBD (appendix). This version of DisMod-MR allows for two types of fi xed eff ects (study attributes and country covariates) and includes nested random eff ects for super-region, region, and country. A key advantage of DisMod-MR is that it can handle data reported for any age interval. Predictions from DisMod-MR for each group divided by country, year, and age are based on the country covariates, reference values of the study level covariates, and hierarchical random eff ects. Point estimates with uncertainty were produced for six discrete points: 1990, 1995, 2000, 2005, 2010, and 2013. Each cause was modelled independently. Predicted cause fractions for each group were rescaled to equal 100% of the deaths not related to HIV. The rescaled cause fractions were then multiplied by the number of maternal deaths in each group (divided by country, year, and age) to obtain the number of deaths for each maternal cause, a sum to which the HIV deaths were added. The fi nal result includes cause fraction and number of maternal deaths due to each cause, country, age group, and year.

Timing of maternal deathsAn important issue for planning of interventions is an understanding of the timing of maternal deaths with respect to labour and delivery.47 We completed a systematic review to identify studies of the timing of maternal deaths (appendix). We identifi ed 142 studies and used vital registration, sample registration, and surveillance data for late maternal death. Many studies combined the fi rst 24 h postpartum (immediate or early postpartum) with the intrapartum period, because events of the immediate postpartum period are clinically related to events occurring during labour and delivery. Therefore, we also combined intrapartum and immediate postpartum periods. We followed this format to construct a dataset that included four diff erent time windows: deaths occurring antepartum (before onset of labour), deaths occurring intrapartum or during the immediate postpartum period (up to 24 h after delivery), deaths occurring during the subacute and delayed postpartum periods (24 h to 42 days after delivery),47 and late maternal deaths (43 days to 1 year after delivery). We modelled the proportion of maternal deaths in each of the four periods with DisMod-MR (version 2.0). The predicted proportions were scaled to 100% for each group.

2030 scenario and rate-of-change calculationsWe developed a straightforward forecast scenario for the MMR for every country in 2030 by using the estimated

Cause patterns vary by regions. The two most important causes of maternal death in high-income regions in 2013 were indirect and other direct causes (fi gure 6B), owing largely to a decrease in abortion-related deaths, which was the most important cause of maternal mortality in high-income regions in 1990. The number of deaths due to haemorrhage, hypertension, and maternal sepsis have also decreased signifi cantly, whereas the numbers of deaths due to indirect and late maternal causes have increased since 1990 (fi gure 6B, appendix). By contrast, the most important causes in low-income countries—other direct, abortion, and haemorrhage—have not changed between 1990 and 2013, although diff erent trends are apparent in diff erent

regions. For example, east Asia had signifi cant decreases in all causes except HIV (which was estimated to be the cause of 0·003% of all maternal deaths in 2013; appendix). The total global number of HIV-related maternal deaths in 2013 was 2070 (95% UI 1290–2866), reduced from a peak of 3280 (2041–4403) in 2004. The increase in proportion of deaths due to indirect maternal causes was most notable in Latin America and the Caribbean, where the proportion increased from 9·2% (95% UI 8·8–9·8) in 1990, to 11·5% (10·9–12·2) in 2013.

In 2013, on average, nearly a quarter of deaths occurred antepartum (24·6%, 24·1–25·2), a quarter intrapartum and immediately postpartum (27·7%, 27·1–28·2), a third
