ArticlePublication 2020Interpreting COVID-19 Test Results: A Bayesian Approach
This article considers the following question with respect to interpreting the results of polymerase chain reaction …
This article considers the following question with respect to interpreting the results of polymerase chain reaction (PCR) assays from nasal and pharyngeal swabs for COVID-19 to inform clinical decision making: "While a positive result in an acutely ill patient is straightforward, how should physicians interpret negative tests in patients with suspected COVID-19 infection?" Using an assumption of near-perfect specificity of PCR assays for COVID-19, the authors acknowledge the uncertainty of test sensitivity. They consider two clinical scenarios…

ArticlePublication 2019Systematic Review of Economic Evaluations of Vaccination Strategies Against Tuberculosis
Bacillus Calmette-Guérin (BCG) is the only licensed vaccine for tuberculosis, but its effectiveness is limited …
Bacillus Calmette-Guérin (BCG) is the only licensed vaccine for tuberculosis, but its effectiveness is limited and varies by age, so a valid cost-effectiveness study is needed to assist decision-makers in the implementation of cost-effective strategies for BCG vaccination. Using the Quality of Health Economic Studies (QHES) instrument, the authors assessed the quality of published studies involving economic evaluations of BCG vaccination strategies in a variety of regions, target populations, and vaccine types. Most of the…

ArticlePublication 2019Cost-Effectiveness of Latent TB Screening before Immigration to Low-Incidence Countries
Despite prospective migrants to countries where the incidence of TB is low receiving TB screening …
Despite prospective migrants to countries where the incidence of TB is low receiving TB screening for active infections, screening for latent TB infection before immigration is rare. The authors used discrete event simulation to evaluate the cost-effectiveness preimmigration latent TB infection screening for migrants to low-incidence countries. They calculated cost per quality-adjusted life-year gained for migrants from countries with different TB incidences. Their analysis when combined with research on sustainability, acceptability, and program implementation can…

ArticlePublication 2018Comparing Cost-per-QALYs Gained to Cost-per-DALYs Averted
The authors examined 6,438 cost-per-QALY and 543 cost-per-DALY studies published through 2016 using two databases, …
The authors examined 6,438 cost-per-QALY and 543 cost-per-DALY studies published through 2016 using two databases, the Tufts Medical Center CEA Registry (cost-per-QALY gained studies), and the Global Cost-Effectiveness Analysis (GHCEA) Registry (cost-per-DALY averted studies). Study characteristics that were analyzed included intervention type, sponsor, country, primary disease, and number of CEAs versus disease burden estimates for major conditions. The authors report that cost-per-QALY studies were most often about pharmaceuticals or interventions in high-income countries while cost-per-DALY…

The EuroQol Group first met in 1987 in order to develop a standardized non-disease specific instrument to describe and value health-related quality of life. A process based on shared development, local experimentation and discussion resulted in EQ-5D, a measure that generates a single index value for health status for use in health care evaluation. EQ-5D is a standardized instrument developed as a measure of health-related quality of life that can be used in a wide…

Testing for and treating latent tuberculosis infection (LTBI) is among the main strategies to achieve …
Testing for and treating latent tuberculosis infection (LTBI) is among the main strategies to achieve TB elimination in the United States. This analysis estimated health outcomes, costs, and cost-effectiveness of LTBI testing and treatment among non-US born residents with and without medical comorbidities (e.g., diabetes, HIV infection, and end-stage renal disease). A decision analytic tree and Markov cohort simulation model was used to compare the following strategies: no testing, tuberculin skin test (TST), interferon gamma release assay…

ArticlePublication 2017Making Fair Choices on the Path to UHC: Applying Principles to Difficult Cases

Progress toward universal health coverage (UHC) requires making difficult trade-offs. The World Health Organization (WHO) Consultative Group on Equity and UHC has endorsed the principles for making such decisions. These principles include maximizing population health, priority for the worse off, and shielding people from health-related financial risks. But how should one apply these principles in particular cases, and how should one adjudicate between them when their demands conflict? This article by some members of the…

ArticlePublication 2017Likelihood Approach for Calibration of Stochastic Epidemic Models
Stochastic transmission dynamic models are especially useful for studying the early emergence of novel pathogens …
Stochastic transmission dynamic models are especially useful for studying the early emergence of novel pathogens given the importance of chance events when the number of infectious individuals is small. However, methods for parameter estimation and prediction for these types of stochastic models remain limited. This paper describes a calibration and prediction framework for stochastic compartmental transmission models of epidemics. The proposed method applies a linear noise approximation to describe the size of the fluctuations, and…

The objective of this study was to assess the cost effectiveness of a government policy combining targeted industry agreements and public education to reduce sodium intake in 183 countries worldwide. To account for heterogeneity in efficacy across countries, a range of scenarios were evaluated, including 10%, 30%, 0.5 g/day, and 1.5 g/day sodium reductions achieved over 10 years. Country specific costs of a sodium reduction policy were estimated using the WHO Noncommunicable Disease Costing Tool. Country…
