ArticlePublication 2020Conspiracy Theories as Barriers to Controlling the Spread of COVID-19 in the U.S.
This article uses national probability survey data of U.S. adults to assess the relationship between …
This article uses national probability survey data of U.S. adults to assess the relationship between belief in three COVID-19-related conspiracy theories to adoption of preventive measures recommended by public health authorities, vaccination intentions, conspiracy beliefs, perceptions of threat, belief about the safety of vaccines, political ideology, and media exposure patterns. Authors found that conspiracy theory beliefs were highly stable across two periods of the survey and inversely related to the (1) perceived threat of the…

ArticlePublication 2018Addressing Health-Related Misinformation on Social Media
Policy makers and the social media industry grapple with the challenge of curbing fake news, …
Policy makers and the social media industry grapple with the challenge of curbing fake news, disinformation, and hate speech; and the field of medicine is similarly confronted with the spread of false, inaccurate, or incomplete health information. This viewpoint argues that medical, public health, social science, and computer science experts must begin working together via interdisciplinary research to address health misinformation on social media, with a focus on the following four themes: (1) defining the…

ArticlePublication 2021Distributional Health and Financial Consequences of Increased Cigarette Tax in Iran: An ECEA
This study examines the potential impact of a tax-induced cigarette price increase on financial and …
This study examines the potential impact of a tax-induced cigarette price increase on financial and health outcomes across different socioeconomic groups in Iran. Using pooled cross-sectional data from Household Income and Expenditure Surveys (2002–2017) and population data from Iran in 2019, an extended cost-effectiveness analysis (ECEA) methodology is employed to model the effects of a hypothetical increase in cigarette tax. The analysis evaluates health benefits, health expenditures averted, additional tax revenues generated, changes in household…

ArticlePublication 2021Alleviating the Burden of Diabetes with Health Equity Funds: Economic Evaluation of the Health & Financial Risk Protection Benefits in Cambodia
This study examines the potential distributional health and financial impacts of implementing strategies to provide …
This study examines the potential distributional health and financial impacts of implementing strategies to provide financial coverage for diabetes services through Health Equity Funds (HEF) in Cambodia. Utilizing a Markov model, the trajectory of diabetes is projected over a 45-year period to estimate societal costs, health outcomes, and individual out-of-pocket expenditures associated with six HEF coverage strategies. Input parameters are derived from published literature and household survey data. Strategies covered different combinations of types of…

ArticlePublication 2020Testing for SARS-CoV-2 Antibodies
Antibody testing can determine previous exposure to SARS-CoV-2 virus. Recently, the UK government has made …
Antibody testing can determine previous exposure to SARS-CoV-2 virus. Recently, the UK government has made antibody testing available to anyone wanting it, even if there is no clinical indication. The purpose of this article is to provide guidance for when to consider antibody testing in individuals with and without symptoms suggestive of current or past SARS-CoV-2 infection. Key points made by the authors include: (1) antibody testing is likely to be most useful 2 weeks…

ArticlePublication 2020New Fronts in the War on Misinformation
The countless false claims that have spread alongside the novel coronavirus – inaccurate advice about …
The countless false claims that have spread alongside the novel coronavirus – inaccurate advice about how to prevent the virus, for example, and conspiracy theories about its origins – are just the latest manifestation of an ongoing problem: the online proliferation of misinformation about science and health. The National Academies hosted and helped organize three events focused on countering misinformation: The MisinfoCon conference, a Wikipedia Edit-a-thon, and a meeting to explore ways to expand successful…

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…

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 2020Incorporating Perspective into Clinical Decisions
Part of a six-part series of articles on clinical decision making, in this article, the …
Part of a six-part series of articles on clinical decision making, in this article, the authors discuss how to incorporate perspective into clinical decisions, explicitly acknowledging that the treating physician is not the only stakeholder in these decisions. The authors use 2 case studies to demonstrate how changes in perspective can alter the clinical decision as well lead to both intended and unintended consequences to the outcomes.
