The evolution of simulation from an educational tool to an emerging evaluative tool has been rapid. Physician certification has a long history and serves an important role in assuring that practicing physicians are competent and capable of providing a high level of safe care to patients. Traditional assessment methods have relied mostly on multiple-choice exams or continuing medical education exercises. These methods may not be adequate to assess all competencies necessary for excellence in medical practice.
BackgroundTraditional metrics of the impact of the Affordable Care Act (ACA) and health insurance marketplaces in the United States include public opinion polls and marketplace enrollment, which are published with a lag of weeks to months. In this rapidly changing environment, a real-time barometer of public opinion with a mechanism to identify emerging issues would be valuable.ObjectiveWe sought to evaluate Twitter’s role as a real-time barometer of public sentiment on the ACA and to determine if Twitter sentiment (the positivity or negativity of tweets) could be predictive of state-level marketplace enrollment.MethodsWe retrospectively collected 977,303 ACA-related tweets in March 2014 and then tested a correlation of Twitter sentiment with marketplace enrollment by state.ResultsA 0.10 increase in the sentiment score was associated with an 8.7% increase in enrollment at the state level (95% CI 1.32-16.13; P=.02), a correlation that remained significant when adjusting for state Medicaid expansion (P=.02) or use of a state-based marketplace (P=.03).ConclusionsThis correlation indicates Twitter’s potential as a real-time monitoring strategy for future marketplace enrollment periods; marketplaces could systematically track Twitter sentiment to more rapidly identify enrollment changes and potentially emerging issues. As a repository of free and accessible consumer-generated opinions, this study reveals a novel role for Twitter in the health policy landscape.
A simulated transesophageal examination of normal cardiac anatomy in concert with a standardized assessment tool permits ample discrimination between expert and novice echocardiographers as defined for this investigation. Future research will examine in detail the role echocardiography simulators should play during echocardiography training including assessment of training level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
