ArticlePublication 2020Distributional Impact of Supplementary Immunization Activities: Measles
Although evidence shows that inequalities in under-5 mortality in low- and middle-income countries are decreasing, …
Although evidence shows that inequalities in under-5 mortality in low- and middle-income countries are decreasing, disparities persist and highlight the need to prioritize inequality reduction and equity in decision-making at the global and national levels. This article studied the differential coverage impact of routine delivery versus supplementary immunization activities (e.g., campaigns) for the delivery of measles vaccine in defining and comparing an equity impact number across the two distinct vaccine delivery modes. The analysis can…

ArticlePublication 2022COVID-19 Response: The Need for Economic Evaluation
COVID-19-related policies are fraught with trade-offs. Many of these trade-offs involve dimensions that can be …
COVID-19-related policies are fraught with trade-offs. Many of these trade-offs involve dimensions that can be quantitatively weighed using economic evaluation, such as those between health and cost outcomes. Other types of dimensions, such as those involving equity or autonomy, can be harder to quantify but should be considered in a comprehensive health policy decision-making context nonetheless. The authors of this New England Journal of Medicine Perspectives article outline how methods of economic evaluation and decision…

ArticlePublication 2022Spatial-Mechanistic Model to Estimate Sub-National Tuberculosis Burden in Brazilian Municipalities
Reliable subnational estimates of TB incidence are needed to focus disease control resources in areas …
Reliable subnational estimates of TB incidence are needed to focus disease control resources in areas of highest need. This study developed an approach for generating small area estimates of TB incidence, and the fraction of individuals missed by routine case detection, based on available notification and mortality data. The approach is demonstrated by estimating TB outcomes for 5568 municipalities in Brazil, revealing substantial subnational differences in disease burden and other metrics useful for designing high-impact…

ArticlePublication 2022Systematic Review of Patient Preferences, Expectations, and Values for Management and Treatment of Hypertension
This analysis summarized the evidence on the preferences, expectations, and values of hypertension management and …
This analysis summarized the evidence on the preferences, expectations, and values of hypertension management and treatment in hypertensive patients. The authors reviewed 24 studies involving 8,701 participants. Despite varying areas of focus, common themes included (1) patients often obtain hypertension information from their physicians and prefer shared patient-centered decision-making, and (2) side effects, cost, and convenience are important factors for patients when selecting a treatment regimen for hypertension.

ArticlePublication 2021New Microsimulation Models to Inform Cervical Cancer Control
Health decision models consider the lifetime natural history of human papillomavirus (HPV) infection and pathogenesis …
Health decision models consider the lifetime natural history of human papillomavirus (HPV) infection and pathogenesis of cervical cancer, and estimate the long-term impact of preventive interventions. We propose a new health decision modeling framework that de-emphasizes previously used cytologic-colposcopic-histologic diagnoses, which are subjective and lack reproducibility, relying instead on HPV type and duration of infection as the major determinants of model transition probabilities. We posit that new model health states and corollary transitions are universal,…

ArticlePublication 2019Estimating the Total Incidence of Global Childhood Cancer: A Simulation-Based Analysis
This study describes the development of a microsimulation model to simulate childhood cancer incidence for …
This study describes the development of a microsimulation model to simulate childhood cancer incidence for 200 countries/territories, taking into account trends in population growth and urbanicity, geographical variation in cancer incidence, and health system barriers to access and referral that contribute to underdiagnosis. The model was calibrated to publicly available cancer registry data, and the total incidence of childhood cancer (diagnosed and undiagnosed) was estimated for each country in 2015 and projections made to 2030.…

ArticlePublication 2019Projected U.S. State-Level Prevalence of Adult Obesity and Severe Obesity
This analysis estimates state-specific and demographic subgroup-specific trends and projections of the prevalence of categories …
This analysis estimates state-specific and demographic subgroup-specific trends and projections of the prevalence of categories of body-mass index (BMI) in the United States. Self-reported BMI from the Behavioral Risk Factor Surveillance System Survey (1993-1994 and 1999-2016) were obtained and corrected for quantile-specific self-reporting bias. Multinomial regressions were then fitted for each state and subgroup to estimate the prevalence of four BMI categories from 1990 through 2030: underweight or normal weight (BMI <25), overweight (25 to…

ArticlePublication 2022Excess Mortality and Elevated Body Weight in the U.S.
This analysis estimates excess mortality associated with elevated body weight in the United States by …
This analysis estimates excess mortality associated with elevated body weight in the United States by state and demographic subgroup. The authors developed a nationally-representative microsimulation (individual-level) model of US adults between 1999 and 2016, based on risk factor data from the Behavioral Risk Factor Surveillance System and body-mass index (BMI) mortality hazard ratios from a global pooling dataset. The model was calibrated to empirical all-cause mortality rates from CDC WONDER by state and subgroup, and…

ArticlePublication 2021Impact of Treatment and Imaging Modalities on Global Breast Cancer Survival
This analysis used a microsimulation model of global cancer survival to simulate 5-year net survival …
This analysis used a microsimulation model of global cancer survival to simulate 5-year net survival for women with newly diagnosed breast cancer in 200 countries/territories in 2018, accounting for the availability and stage-specific survival impact of specific treatment modalities (chemotherapy, radiotherapy, surgery, and targeted therapy), imaging modalities (ultrasound, x-ray, CT, MRI, PET, and single-photon emission computed tomography [SPECT]), and quality of cancer care. The model was calibrated to empirical data on 5-year net breast cancer…
