Geographic Distribution of Maternal and Neonatal Mortality and Inequalities in Obstetric Emergency Care Supply in Ecuador, 2006–2024
This ecological study of Ecuador (2006–2024) reveals that while maternal and neonatal mortality lack significant provincial-level spatial clustering due to a modifiable areal unit effect, a cantonal-level analysis uncovers critical geographic disparities where over 16% of cantons face simultaneous shortages of obstetric beds and workforce, highlighting specific infrastructure gaps distinct from workforce deployment as actionable targets for intervention.

Every year, thousands of women and newborns die from complications that should be preventable. These tragedies are not just random misfortunes; they are often the result of a health system that fails to reach people when they need it most. When a pregnancy becomes dangerous, the difference between life and death frequently comes down to two things: whether a skilled doctor or midwife is available, and whether there is a hospital bed with the right equipment nearby. For decades, health experts have tried to map these gaps, looking for patterns in where deaths happen and where care is missing. The goal is simple but urgent: to find the places where the system is broken so that resources can be sent exactly where they are needed. In many parts of the world, these patterns are obvious, with clusters of high death rates appearing in specific regions. But in some places, the map looks confusingly empty, leaving researchers to wonder if the danger is truly everywhere, or if the way they are looking at the map is simply too broad to see the cracks.
A new study from Ecuador, covering the years 2019 through 2024, set out to solve this puzzle. The researchers wanted to know if maternal and newborn deaths were clustered in specific provinces, or if they were scattered randomly across the country. They also wanted to measure the supply of emergency care—counting hospital beds for childbirth and the number of doctors and midwives—to see if the places with the most deaths were the same places with the least care. To do this, they gathered data on over 1,000 maternal deaths and more than 10,000 newborn deaths. They cross-referenced these numbers with a detailed history of hospital beds and workforce counts, looking at data from as far back as 2006. They also looked at a broader category of "near-miss" cases, where women survived life-threatening complications, to get a clearer picture of the severity of obstetric emergencies beyond just the deaths. A critical constraint of this study was that a live-birth registry was unavailable; consequently, all rates were calculated using the total population as the denominator rather than the number of live births. This means the results cannot be directly compared to international Maternal Mortality Ratio or Neonatal Mortality Rate statistics, a significant limitation the researchers treated as a primary caveat throughout their analysis.
When the researchers first looked at the data by province, the results were surprising. Unlike other health issues in Ecuador, such as kidney disease or suicide, which show clear geographic clusters, the deaths of mothers and newborns did not seem to group together in any specific province. Statistically, the map looked flat. There was no single region that stood out as a hot spot for these tragedies when viewed from this distance. This lack of a pattern led some to wonder if the problem was truly uniform across the country, or if the way the data was being grouped was hiding the truth. The researchers suspected that the answer lay in the size of the map they were using. Just as a satellite photo might show a forest as a solid green block, missing the individual trees and clearings, looking at the country in large chunks might be blurring the specific, dangerous spots where care is missing.
To test this, the team zoomed in. Instead of looking at the 24 large provinces, they broke the country down into its 208 smaller cantons, which are like counties or municipalities. This finer view changed everything. While the maternal deaths still did not show a strong pattern, the deaths of newborns suddenly revealed a clear cluster. One specific area, the canton of Santa Rosa in the province of El Oro, emerged as a distinct hotspot where newborn deaths were concentrated. This finding proved that the earlier "flat" map was an illusion caused by the scale of the analysis. The danger was not spread evenly; it was concentrated in specific, smaller communities that were being averaged out when viewed from the provincial level.
The study also uncovered a stark reality about the health system's infrastructure that was hidden by the provincial averages. When looking at the country as a whole, it appeared that every province had at least some doctors or midwives. However, when the researchers looked at the canton level, they found that 37 of the 221 cantons had absolutely no obstetric beds and no doctors or midwives at all. These were "double deserts" of care. In some provinces, like Morona Santiago, the situation was particularly dire: the province had the highest combined burden of maternal and newborn deaths, yet it had zero obstetric beds. The doctors and midwives were there, but the physical infrastructure to save lives was missing. Similarly, in the canton of Río Verde, the researchers found the worst mismatch in the entire country, where the need for care was highest but the supply of both beds and staff was zero.
The researchers also tracked how the number of hospital beds had changed over time. They found that the total number of beds for gynecology and obstetrics had grown significantly between 2006 and 2019. However, a change in how the government counted these beds in 2022 made it difficult to compare the most recent numbers directly with the past. Despite this, the data showed a worrying trend in the severity of complications. The number of women hospitalized for severe, life-threatening pregnancy complications had roughly doubled between the early 2000s and the early 2020s. This increase could mean that more women are surviving dangerous situations because they are reaching hospitals, or it could mean that the complications themselves are becoming more common. Either way, it signals that the pressure on the emergency system is growing.
The most important takeaway from this work is that the solution to these deaths requires a very specific kind of targeting. The study shows that simply sending more doctors to a province is not enough if there are no beds for them to work in. In places like Morona Santiago, the bottleneck is not a lack of trained people, but a lack of hospital infrastructure. Conversely, in other areas, the problem might be the opposite. The study also highlights that looking at the country in broad strokes can be dangerous. By zooming in to the canton level, the researchers identified specific communities that are invisible in national statistics but are suffering the most. These findings provide a clear roadmap for policymakers: they need to build beds in the provinces that have none, and they need to send resources to the specific cantons where both beds and staff are missing. The map of danger is not a blur; it is a set of precise locations waiting to be fixed.
