New articles in the GANM Library - COVID 19 and Access to Care/Knowledge

Jan 09, 2021

Dear GANM Community, 


In this week’s edition of the GANM Library Research Brief we would like to focus on access to healthcare and health knowledge. With the persistence of COVID-19 and cases continuing to rise in the United States as well as other areas of the world, we need to focus on this important concept in order to increase health overall.



Thorpe, A., Scherer, A. M., Han, P. K. J., & Fagerlin, A. (2021). Exposure to common geographic COVID-19 prevalence maps and public knowledge, risk perceptions, and behavioral intentions. JAMA Network Open, 4(1):e2033538. doi:10.1001/jamanetworkopen.2020.33538


In a recent article published in JAMA, researchers assessed the association of 6 different COVID-19 maps with knowledge, risk perceptions and behavioral intentions in. According to the investigators multiple maps by various organizations have been produced but lack data on what the map entails in terms of important information. Through a survey results showed that not viewing a map was associated with higher levels of knowledge regarding total cases. The researchers believe that this is a call to action for organizations producing visual aids (maps) to alter the manner in which they disseminated their information in order to improve access to health knowledge and improve understanding of information.



Angulo, F. J., Finelli, L., Swerdlow, D. L. (2021). Estimation of US SARS-CoV-2 Infections, symptomatic infections, hospitalizations, and deaths using seroprevalence surveys. JAMA Network Open, 4(1):e2033706. doi:10.1001/jamanetworkopen.2020.33706


What has the burden of disease been for the SARA-CoV-2 virus (COVID-19) in the United States? This is the question many across the nation and world are asking. In this cross-sectional study using surveys there were an estimated 47 million with approximately 28 million being symptomatic. In addition, there were about 956,000 hospitalizations and 305,000 deaths (as of November 15, 2020). Although 14% of the U.S. population was infected with the virus, there is still a substantial gap before the concept of herd immunity may begin to provide protection.

These findings are absolutely necessary in developing future interventions and improving access to health care.
