Crowdsourcing healthcare costs: Opportunities and challenges for patient centered price transparency

Efforts to improve health care price transparency have garnered significant attention from patients, policy makers, and health insurers.

However, such data often do not provide consumers with the most salient information: their own actual out-of-pocket cost for medical care.  This article explores the challenges and potential opportunities for crowdsourcing out-of-pocket costs for health care consumers.

#Zika

Public sentiment and discourse about Zika virus on Instagram

Social media have strongly influenced awareness and perceptions of public health emergencies, and a considerable amount of social media content is now shared through images, rather than text alone. This content can impact preparedness and response due to the popularity and real-time nature of social media platforms. We sought to explore how the image-sharing platform Instagram is used for information dissemination and conversation during the current Zika outbreak.
