Objectives: Traditionally, business-related projects are either executed by employees within an organization or outsourced to external vendors. Crowdsourcing, on the other hand, allows sponsors to leverage the Internet to draw upon the skills and experiences of the public in open forums to generate new ideas or deliverables. Crowdsourcing for healthcare technology innovation has become increasingly popular; however, the type of stakeholders involved and healthcare technologies sought are not well understood. The aim of this study is to characterize crowdsourcing competitions focused on healthcare technology innovation. Methods: Information was gathered from the Health 2.0 Developer Challenge website, a leading online competition platform where complex healthcare challenges are crowdsourced by sponsoring agencies to teams of developers. Completed challenges listed on the platform from January 2007-October 2014 were identified. For each challenge, total prize money, stakeholder type, and challenge theme were examined. Results: A total of 57 challenges were identified with $3.31 million awarded as total prize money (mean=$75,250; median=$40,000; max=$750,000). Government agencies sponsored the majority of challenges (46%), followed by non-profit (37%) and for-profit (25%) organizations. Four (7%) challenges were sponsored by pharmaceutical companies and accounted for 14% of total prize money (mean=$117,500; median=$150,000; max=$160,000). The five most common challenge themes identified were data management (25%), enhanced decision making (16%), communication barrier (14%), health education (14%), wellness/tracking (11%), and disease prevention/screening (11%).   Conclusions:  Although government agencies were the most common sponsors of crowdsourced healthcare technology challenges, pharmaceutical companies offered the highest mean monetary awards.  Data management solutions (e.g. electronic health record applications) were the most frequently solicited theme among all challenges. Crowdsourcing shows promise as a source of innovative healthcare technology solutions; however, more research is needed to explore the viability of such solutions.
