ArticlePublication 2021COVID-19 Infodemic: Twitter vs. Facebook
The global spread of COVID-19 is affected by the spread of related misinformation – the …
The global spread of COVID-19 is affected by the spread of related misinformation – the so-called COVID-19 infodemic – that makes populations more vulnerable to the disease through resistance to mitigation efforts. This article analyzes the prevalence and diffusion of links to low-credibility content about the COVID-19 pandemic across Twitter and Facebook. They characterize cross-platform similarities and differences in popular sources, diffusion patterns, influencers, coordination, and automation. Comparing the two platforms, authors found divergence among…

ArticlePublication 2021COVID-19 Infodemic: Applying the Epidemiologic Model to Counter Misinformation
Throughout the world, including the U.S., medical professionals and patients are facing both a pandemic …
Throughout the world, including the U.S., medical professionals and patients are facing both a pandemic and an infodemic – the first caused by SARS-CoV-2 and the second by misinformation and disinformation. The Annenberg Public Policy Center’s tracking of social and legacy media has found that millions of people have been exposed to deceptive material alleging that SARS-CoV-2 is a hoax or that experts are exaggerating its severity and the extent of its spread, that masks…

ArticlePublication 2019Countering Misinformation with Lessons from Public Health
The internet is often praised as a tool for freedom of speech, democracy, and truth. …
The internet is often praised as a tool for freedom of speech, democracy, and truth. However, the internet increasingly has become polluted by misinformation – the inadvertent spread of misleading and false information – and disinformation – the deliberate and coordinated spread of misleading and false information. Individuals online knowingly and unknowingly spread dangerous rumors and propaganda at an alarming rate, which can mislead or manipulate the worldview of those who encounter it. False information…

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 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 2015Cancer Models and Real-World Data: Better Together
Decision-analytic models synthesize available data on disease burden and intervention effectiveness to project estimates of …
Decision-analytic models synthesize available data on disease burden and intervention effectiveness to project estimates of the long-term consequences of care. While models have been influential in informing US cancer screening guidelines under ideal conditions, incorporating detailed data on real-world screening practice has been limited given the complexity of screening processes and behaviors throughout diverse health delivery systems in the United States. The authors describe the synergies that exist between decision-analytic models and health care utilization…

ArticlePublication 2015Population Health Model (POHEM): An Overview
This paper provides an overview of the rationale, methodology and applications of the Population Health …
This paper provides an overview of the rationale, methodology and applications of the Population Health Model (POHEM). POHEM is a health microsimulation model, developed at Statistics Canada in the early 1990s. The authors describe that POHEM draws together rich multivariate data from a wide range of sources to simulate the lifecycle of the Canadian population, specifically focusing on aspects of health. The model dynamically simulates individuals’ disease states, risk factors, and health determinants, in order…

ArticlePublication 2013Contribution of H. Pylori and Smoking to US Incidence of Gastric Adenocarcinoma: A Microsimulation Model
Although gastric cancer has declined dramatically in the US, the disease remains the second leading …
Although gastric cancer has declined dramatically in the US, the disease remains the second leading cause of cancer mortality worldwide. This analysis estimates the contribution of risk factor trends on past and future intestinal-type non-cardia gastric adenocarcinoma (NCGA) incidence. The authors developed a population-based microsimulation model of intestinal-type NCGA and calibrated it to U.S. epidemiologic data on precancerous lesions and cancer. The model explicitly incorporated the impact of Helicobacter pylori and smoking on disease natural history, for which…
