The vital registration system in Mexico relies on information collected from death certificates to generate official mortality figures. A study by researchers at IHME and the National Institute of Public Health in Mexico set out to test the validity of this system.
An innovative method of computer-coded verbal autopsy, the Random Forest (RF) Method from machine learning, was found to outperform physician-certified verbal autopsy (PCVA) in almost all settings, according to a study by researchers from IHME and the Bill & Melinda Gates Foundation as part of the Population Health Metrics Research Consortium (PHMRC).
InterVA, an automated and widely available tool for assigning cause of death using verbal autopsies (VAs), does not perform as well as other methods, such as physician-certified verbal autopsy (PCVA) and the Simplified Symptom Pattern (SSP) method, according to a study published by researchers at IHME and the University of Queensland, as part of the Population Health Metrics Research Consortium (PHMRC).
The King and Lu (KL) method for directly estimating the fraction of all deaths in a population due to a given cause has been used to interpret verbal autopsies (VAs) in areas with incomplete vital registration systems.
Physician certification is the most widely used method for interpreting verbal autopsy (VA), yet physicians correctly determine cause of death less than half of the time, according to new research by IHME and the University of Queensland as part of the Population Health Metrics Research Consortium (PHMRC).
For the past three decades, Japan has had the highest life expectancy in the world. This has been achieved while keeping health expenditures as a fraction of gross domestic product (GDP) under 8.5% in 2008, by contrast with 16·4% in the USA or 10.7% in Germany.
“Verbal autopsy: innovations, applications, opportunities” is a collection of the most up-to-date research to help decision-makers choose the best and most cost-effective techniques to identify causes of death in their populations.
Between 2000 and 2007, life expectancies in more than 80% of United States counties fell in standing against the average of the 10 nations with the best life expectancies in the world, according to new research by IHME, in collaboration with researchers from Imperial College London.
The global economic crisis that unfolded in 2008 raised serious concerns about developing countries ability to meet global health targets and commitments to fund health programs. The commentary points out how the uncertainty underscores the importance of tracking spending on global health to ensure resources are directed efficiently to the world's most pressing health issues.
In South Africa, deaths from HIV/AIDS are often misclassified as being caused by another condition, according to a study by IHME researchers. The study found that more than 90% of HIV/AIDS deaths from 1996 to 2006 were incorrectly attributed to other causes.
New research by IHME demonstrates how the quality of mortality data can be improved by redistributing deaths attributed to heart failure to their underlying causes of death according to statistically derived redistribution proportions.
A substantial proportion of individuals with diabetes remain undiagnosed and untreated, in both developed and developing countries, according to a study by IHME researchers and collaborators.
New research shows that global systolic blood pressure (SBP) has decreased slightly since 1980, but trends varied significantly across regions and countries.
Researchers have found wide variability among countries’ efforts to control high cholesterol with medication. Many people in these countries are not aware of their high cholesterol, which significantly increases the risk of heart attack and stroke.
Researchers at IHME have created a new approach for generating estimates of health trends in counties and other small population areas. They used this new small area estimation methodology to estimate the prevalence of diagnosed diabetes in all counties in the United States for 2008, in this study.
In addition to the inherent importance of education and its essential role in economic growth, education and health are strongly related. We updated previous systematic assessments of educational attainment, and estimated the contribution of improvements in women’s education to reductions in child mortality in the past 40 years.
Bed net distribution and use has expanded rapidly across Africa, especially in countries that have received significant health aid for malaria prevention efforts, research shows. The study makes use of an innovative statistical tool that could have broader application in other public health settings.
A program in India that pays women to give birth in a health facility appears to be saving newborns’ lives and lowering the number of stillbirths, as demonstrated by research conducted by IHME.
Mortality in children younger than 5 years is falling in every region of the world, dropping from 11.9 million deaths in 1990 to 7.7 million deaths in 2010, according to research by IHME. These figures represent a 35% reduction in under-5 mortality within 10 years, a rate of decline that was faster than expected.
Valid, reliable, and comparable assessments of trends in causes of death are limited by a number of factors.
The most comprehensive assessment to date of global adult mortality shows how health disparities among countries and between men and women are widening around the world.
Public financing of health by domestic governments nearly doubled between 1995 and 2006, according to IHME research. The study also analyzes the effect of development assistance for health, gross domestic product, government size, debt relief, and HIV prevalence on government health spending from domestic sources.
A novel analytical technique shows that more adults are dying between the ages of 15 and 60 in developing countries than previously thought, according to new research. Additionally, the new techniques provide a tool for directly measuring the impact of HIV instead of relying solely on theoretical models.
Research shows that new analytical methods can measure child mortality more accurately and less expensively, enabling policymakers to respond more quickly to pressing public health concerns. The study shows how these new methods can be used to evaluate mortality trends in specific regions, revealing health disparities.
Novel techniques can make better use of incomplete vital registration systems for population health studies, according to new research. The study describes an approach to check the completeness and accuracy of databases that compile information from death certificates.
