EditorialPublication 2020Waiting for Certainty on COVID-19 Antibody Tests — At What Cost?
This perspective anticipates the availability of serologic antibody testing and considers its potential usefulness in mitigation …
This perspective anticipates the availability of serologic antibody testing and considers its potential usefulness in mitigation policy to reduce COVID-19 transmission. For example: Could we screen for serologic antibodies as a proxy for possible immunity and identify people who could return to the workplace with less severe mitigation measures? The authors acknowledge the uncertainties raised by many policy actors, including the WHO, such as, "Do antibodies confer immunity and, if so, for how long? How accurate is…

ArticlePublication 2020Bayes' Theorem, COVID-19, and Screening Tests
This article reviews the implications of increased testing for COVID-19 using reverse transcriptase polymerase chain …
This article reviews the implications of increased testing for COVID-19 using reverse transcriptase polymerase chain reaction (rRT-PCR) through the application of Bayes’ Theorem for three hypothetical, stylized case scenarios. The scenarios involve three patients with a low, moderate, and high pre-test probability of COVID-19 infection. The category of low probability would include "asymptomatic individuals in a presumed low prevalence environment" and might vary from 10 to 20%. The category of moderate probability would include "individuals…

Tools/ModelsInteractive, Teaching Resource 2020Interactive Graphic: Interpreting a COVID-19 Test Result
Currently, the most common diagnostic test for COVID-19 relies on reverse transcriptase polymerase chain reaction …
Currently, the most common diagnostic test for COVID-19 relies on reverse transcriptase polymerase chain reaction (RT-PCR), and most often uses samples obtained from the respiratory tract by nasopharyngeal swab. This interactive graphic demonstrates the influence of the prior probability of COVID-19, the test sensitivity (i.e., the probability of a positive test conditional on disease presence), and the test specificity (i.e., the probability of a negative test conditional on disease absence) on the post-test probability of…

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…

ToolInteractive, Teaching Resource 2020RAND Critical Care Surge Response Tool
This Excel-based model allows decisionmakers at all levels (i.e., hospitals, health care systems, states, regions) …
This Excel-based model allows decisionmakers at all levels (i.e., hospitals, health care systems, states, regions) to examine the current critical care capacity in the nation’s hospitals and rapidly explore strategies for increasing capacity to provide care for the sickest COVID-19 patients. The tool was developed by the RAND Corporation in response to the 2020 COVID-19 pandemic. Model input parameters to the Excel spreadsheet include baseline number of beds, critical care doctors and nurses, respiratory therapists,…

This data portal is the World Health Organization's (WHO) main health statistics repository. The Global Health Observatory (GHO) provides access to more than 1,000 indicators on priority health topics including mortality and burden of diseases, the Sustainable Development Goals, noncommunicable diseases and risk factors, epidemic-prone diseases, health systems, environmental health, violence and injuries, and health equity. In addition, the GHO provides access to WHO's analytical reports on the current status and trends of priority health…

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…

The authors used a systematic review of the literature to identify economic evaluations of rotavirus …
The authors used a systematic review of the literature to identify economic evaluations of rotavirus vaccine in LMICs and assess the extent to which equity was considered in the objectives, analysis, and results. They used equity-related indicators provided in the Guidance on Priority Setting in Health Care (GPS-Health) checklist criteria resulting in 18 unique indicators tracked. The authors found that some articles incorporated the indicators in their model inputs (20%) while the majority (80%) presented…

The authors examine the complexities of the vaccine enterprise, a fundamental component of preventive medicine and public health, from research and development of new vaccines to financing and reimbursement of immunization services. The current climate, socially, economically and politically, presents challenges and opportunities to the U.S. to strengthen the existing systems of developing, manufacturing, regulating, distributing, funding, and administering safe and effective vaccines for all people. The authors present recommendations for priority actions intended to…
