Background: traditional 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. objective: we 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. methods: we retrospectively collected 977,303 aca-related tweets in march 2014 and then tested a correlation of twitter sentiment with marketplace enrollment by state. results: a 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). conclusions: this 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. ©charlene a wong,maarten sap,andrew schwartz,robert town,tom baker,lyle ungar,raina m merchant.
